Bay Area sellers should prepare three different layers before listing: the disclosures required for the property and transaction, any city or utility compliance work triggered by the transfer, and a selective set of pre-listing inspections that will improve the sale plan. They overlap, but they are not interchangeable.
For many covered one-to-four-unit residential sales, the baseline file includes the California Transfer Disclosure Statement and Natural Hazard Disclosure, known material facts and prior reports, the federal lead disclosure for most pre-1978 housing, and HOA resale documents when applicable. Exemptions and additional notices remain property- and transfer-specific.
There is no single “Bay Area disclosure package” and no statewide rule requiring every seller to order a general home inspection before listing. The right checklist depends on the exact address, property type, age, ownership and occupancy, as well as what the seller already knows. Start early enough to verify those facts before marketing or an accepted offer creates a deadline.
This is educational planning guidance, not a legal conclusion or a substitute for qualified property specialists. Current duties, exemptions and condition conclusions must be confirmed for the actual property and transfer.
The short answer: use a three-layer framework
| Layer | What belongs in it | Core question |
|---|---|---|
| 1. Legally required disclosures | California and federal forms, known material facts, prior reports and property-specific records | What information must this buyer receive? |
| 2. Local transfer and compliance requirements | City or utility inspections, reports, repairs, certificates, exemptions and approved extensions | What must this address complete or document because title is transferring? |
| 3. Optional or customary pre-listing inspections | General home, pest, roof, sewer, chimney and other risk-based specialist inspections | Which additional facts would improve pricing, preparation and transaction certainty? |
Keep four terms separate:
- A disclosure communicates facts. It is not a warranty, repair promise or professional opinion about every component.
- An inspection observes or tests only the items within that inspector's defined scope. It does not replace the seller's own disclosure duties.
- A report records findings or government records. A San Francisco 3R report, for example, is a records report—not a physical inspection or a declaration that the building complies with current law.
- A compliance certificate confirms that a specific program's requirements were satisfied or formally deferred. It does not certify the entire property.
That distinction prevents a common mistake: handing buyers an inspection report and assuming the seller no longer needs to explain what the seller personally knows.
Layer 1: build the legally required disclosure file
Start with the California Transfer Disclosure Statement
California's statutory transfer-disclosure rules generally apply to transfers of one-to-four-unit residential property, including many condominium and planned-development resales, subject to stated exemptions. The Real Estate Transfer Disclosure Statement, commonly called the TDS, asks the seller to identify property features and disclose known defects, malfunctions and other conditions.
The TDS is not an inspection and is not a warranty. The seller answers from actual knowledge; a real estate licensee has a separate statutory role that includes a reasonably competent and diligent visual inspection in covered one-to-four-unit transactions. Neither role should be treated as a substitute for an engineer, contractor, environmental professional or other specialist.
Complete the seller's disclosures carefully rather than guessing, diagnosing or using an inspection report as a shortcut. If a question is unclear, identify the underlying facts and ask the appropriate real estate or legal professional how they should be presented.
California requires the TDS to be delivered as soon as practicable before transfer of title. If a disclosure required by the TDS article—or a material amendment to one—is delivered after an offer is executed, Civil Code Section 1102.3 gives the buyer a statutory termination period: three days after personal delivery or five days after delivery by mail or agreed electronic record. Early delivery is therefore more than an organizational preference; timing can affect the buyer's rights and the transaction.
Some transfers—such as specified court-ordered, foreclosure, fiduciary, co-owner, family and governmental transfers—may be exempt from the TDS article. The exemption language is specific, and an exemption from this form does not automatically eliminate every other disclosure duty, federal rule or local transfer requirement. Trust, probate, conservatorship and court-connected sellers should have the applicable exemption and remaining duties confirmed rather than inferred.
Prepare the Natural Hazard Disclosure separately
The Natural Hazard Disclosure Statement, or NHD, addresses whether the property lies within mapped hazard areas. The current statutory statement includes:
- FEMA special flood hazard areas;
- potential dam-failure inundation areas;
- high or very high fire hazard severity zones, with the current form distinguishing high and very high zones in state responsibility areas and very high zones in local responsibility areas;
- designated wildland fire areas;
- earthquake fault zones; and
- seismic hazard zones for landslide or liquefaction.
A third-party natural-hazard report is commonly used to support this disclosure, but the NHD is still only a map-based disclosure. It does not predict whether a specific home will flood, slide, burn or experience earthquake damage, and it does not determine insurance availability or cost. A seller or agent's other known material information is not erased by the report.
Disclose known material facts beyond the checkboxes
California's statutory forms are not an exhaustive list of everything that can matter. The current Civil Code preserves duties intended to prevent fraud, misrepresentation or deceit and expressly recognizes material facts affecting value or desirability, including physical condition and previously received inspection reports.
Build a factual property history before answering forms. Useful records can include:
- prior inspection, engineering, pest, roof, sewer, environmental and repair reports;
- permits, final approvals, plans, invoices, warranties and contractor information;
- additions, conversions, repairs or alterations, including work whose permit status is uncertain;
- water intrusion, drainage, flooding, settlement, movement, leaks, backups, fires or other recurring events;
- insurance claims and the work completed after a loss;
- shared driveways, fences, retaining walls, sewer lines or other maintenance arrangements;
- easements, encroachments, boundary questions or notices affecting use;
- tenant, occupant or access arrangements; and
- correspondence from an HOA, insurer, contractor, city, utility or neighbor about a property condition.
Describe what happened, when it happened, what was observed and what records exist. Avoid converting an observation into a technical conclusion outside your expertise. “Water entered at the lower wall during the January storm; invoice and drying report attached” is more useful than an unsupported claim that the issue is permanently solved.
An “as-is” sale does not waive the TDS article where it applies or authorize concealment of known material facts. It may affect who agrees to perform or pay for repairs, but other disclosure duties still must be analyzed under the law that governs the property and transaction.
Add the federal lead-based-paint disclosure for most pre-1978 housing
Federal law applies to most housing built before 1978, with defined exemptions. Before a buyer is obligated under a contract for covered housing, the seller must provide the approved lead-hazard pamphlet, disclose known lead-based paint or lead hazards, provide available records and reports, and include the required warning and acknowledgment language in the contract process.
The buyer must also receive a 10-day opportunity to conduct a lead inspection or risk assessment unless the parties agree in writing to a different period or the buyer waives the opportunity in writing. The federal disclosure rule does not generally require the seller to conduct or pay for a lead inspection. If the seller already has lead-related records or commissions testing, however, the disclosure file should include the resulting information as required.
Lead disclosure is a good example of why the three layers matter: disclosing known lead information is mandatory for covered housing, but the seller's own lead inspection is not automatically mandatory.
Order the HOA resale documents early
For a California common-interest development, the owner must provide the documents listed in Civil Code Section 4525 as soon as practicable before transfer of title or execution of a real property sales contract. The package can include governing documents, current financial and policy disclosures, assessments and unpaid charges, unresolved violation notices, approved assessment changes, rental restrictions and recent board minutes when requested.
Effective January 1, 2026, the Section 4525 statutory list also includes a copy of the report issued from the most recent exterior-elevated-element inspection conducted under Civil Code Section 5551. Section 5551 has its own applicability and inspection rules, so confirm what report the association actually has rather than assuming every HOA must have the same report. An association report is not a substitute for an inspection of the seller's unit, and a unit inspection does not reveal the association's reserves, insurance, litigation or planned capital work.
Ask the HOA or its manager about turnaround time, current fees, open violations, pending assessments and which party maintains any sidewalk or private sewer lateral. Those responsibility boundaries can determine how a local compliance program applies to an individual unit.
Check for additional property- and transaction-specific notices
Other California disclosures may apply because of the property's location, age, recent ownership history, condition, financing, occupancy or use. Examples can include wildfire defensible-space documentation in covered high and very high fire hazard severity zones; notices about water-conserving plumbing fixtures, special taxes or specified nearby uses; specified contractor-work and permit information when a single-family seller accepts an offer within 18 months after acquiring title; and, beginning January 1, 2026, a seller's duty to disclose in writing actual knowledge of residue from smoking tobacco or nicotine products, or a history of occupants smoking those products on the property. For this rule, smoking expressly includes using an electronic cigarette or vape device to inhale an aerosol. The duty applies to single-family residential property subject to the TDS article.
Tenant-occupied property, solar or other financed equipment, affordable-housing restrictions, seismic programs, manufactured housing, new subdivisions, estates and unusual title structures can add their own documents and professional questions. This guide is not a form inventory. The transaction team should build a property-specific checklist from current law rather than assuming last year's package is complete.
Layer 2: identify local transfer and compliance requirements
Local requirements can apply in addition to the statewide and federal disclosures, and more than one can apply to the same sale. The matrix below covers representative programs in Westin's core Bay Area service area; it is not a complete list of every city, utility district, property type or exemption.
Confirm the exact parcel, jurisdiction, utility service area, building type, HOA responsibility and transfer type directly with the administering agency. Rules, fees, forms, processing systems and extensions can change.
| Place or program | When it may apply | What to prepare before listing | What the resulting document does—and does not—establish |
|---|---|---|---|
| Oakland sidewalk certification | Oakland title transfers, with enumerated exceptions; certain major renovations are a separate trigger | Check the City's records for a valid certificate. If none exists, arrange the required inspection and any repair, then obtain a standard, exemption or—when work cannot be finished before transfer—provisional certificate through OakDOT. The City states that a final compliance certificate is valid for five years and a provisional certificate must be issued before transfer. | Addresses the abutting sidewalk under Oakland's program. It does not inspect the house, private sewer lateral or every HOA walkway. |
| EBMUD Regional Private Sewer Lateral Program | Title transfers for residential, commercial and industrial properties in Alameda, Albany, Emeryville, Oakland, Piedmont, El Cerrito, Kensington and the Richmond Annex, subject to program rules and exemptions | Search the certificate status and determine whether the owner or HOA is responsible. If triggered, obtain an EBMUD Compliance Certificate after the required verification test, or determine whether a 180-day Time Extension Certificate is available before transfer. | Confirms the tested private sewer lateral met the program's leak-free standard. It is not a general plumbing inspection, and Berkeley uses its own sewer-lateral program. |
| Berkeley private sewer lateral | Transfers or sales of Berkeley buildings, including condominiums and developments with shared laterals, subject to stated exceptions | Check for a current City Sewer Lateral Certificate. Without qualifying evidence of prior compliant work, a contractor may need to test, repair or replace the lateral and obtain City verification. Berkeley may approve a six-month extension through its prescribed process in some cases. | Confirms compliance with Berkeley's private-sewer-lateral standard. It does not establish the condition of all plumbing or satisfy Berkeley's separate BESO requirements. |
| Berkeley BESO—single-family homes and duplexes | Sales beginning January 1, 2026, subject to building and transaction exemptions | Obtain a separate Home Energy Score for each unit before listing, place the score in the MLS Property Notes as directed by the City, and include the report and assessment confirmation in disclosure and transfer documents. Before the sale is finalized, follow one City path: obtain a compliance certificate for qualifying upgrades, obtain an approved exemption or complete the formal buyer-deferral and deposit steps at closing. The City's July 2026 guide describes seller-completed upgrades as a pre-listing path. | Documents the BESO assessment and the selected compliance path. It is not a whole-home condition inspection. Attached condominiums, ADUs and other property types have specific treatment that should be confirmed with BESO staff. |
| Berkeley BESO—three- and four-unit residential buildings | Through 2027, the City's current multifamily/commercial time-of-sale compliance path applies; the small-residential resilience standard is scheduled to begin for these properties in January 2028 | Check BESO status before listing and complete an energy assessment, document a qualifying upgrade or exemption, or obtain the formal buyer deferral under the current program. Confirm the rule for mixed-use and larger buildings by size and use. | Addresses energy-assessment or BESO status only. It does not replace physical-condition, HOA, sewer or other disclosures. |
| San Francisco 3R report | Sale or exchange of a residential building, except the first sale or exchange of a newly constructed residential building within one year of its Certificate of Final Completion | Order the Report of Residential Building Record early and deliver it to the buyer before the sale or exchange is completed. Confirm whether separate reports are needed for multiple buildings or individual condominium or cooperative interests. | Reports authorized use and building-permit information found in City records. DBI states that it is not a physical examination, omits plumbing and electrical permit history, and does not represent that the property complies with law. |
| San Francisco residential energy and water conservation | Covered residential title transfers by sale or exchange, subject to exemptions, prior recorded compliance and the code's prescribed postponement or escrow paths | Search for recorded certificates and confirm current applicability with DBI. Where required, obtain qualified energy and water inspections, complete applicable measures and record compliance, or use the formal process that allows responsibility to pass to the buyer with an escrow arrangement. | Confirms only the measures required by the Residential Energy Conservation Ordinance and Residential Water Conservation Ordinance. It is not a general home inspection or a substitute for the 3R report. |
Use the matrix as an address-screening tool
Before proposing a listing date, answer these questions:
- Which city and county have jurisdiction over the parcel?
- Which water and wastewater agencies serve it?
- Is the property one unit, two-to-four units, a condominium, a cooperative, mixed-use or commercial?
- Does an HOA or the individual owner maintain the sidewalk, sewer lateral and exterior components?
- Is there an unexpired certificate, a prior recorded compliance document or an open permit?
- Does the exact transfer qualify for an exemption, deferral or extension?
- Must the requirement be complete before listing, before accepting an offer, before title transfer or after an approved deferral?
Do not assume that a certificate from a prior sale remains valid or covers new work. Download the current record and confirm its expiration and scope with the issuing agency.
Layer 3: choose optional pre-listing inspections by risk
A broad inspection package can create useful certainty, but ordering every available inspection is not automatically the best strategy. Each report has a scope, cost, lead time and disclosure consequence. Select inspections because the result could change preparation, pricing, marketing, buyer audience or transaction risk.
| Inspection or review | When it may be useful | Important limit |
|---|---|---|
| General home inspection | Older homes, unknown maintenance history, inherited property or a seller who wants a broad systems overview | Primarily visual and noninvasive; exclusions and access limitations matter, and specialist follow-up may still be needed. |
| Structural pest inspection | Visible wood damage, moisture, older framing or local market practice | Focuses on wood-destroying organisms and related conditions within the operator's licensed scope; it is not a general structural evaluation. |
| Roof inspection | Older roof, prior leaks, patched areas, solar installation or limited visibility from the ground | Condition and remaining-life opinions are estimates, not guarantees; gutters, drainage and concealed decking may require separate review. |
| Sewer-lateral video or testing | Older piping, backups, mature trees, shared lines or a local compliance trigger | A video and a municipal or utility pressure test answer different questions. Neither evaluates all interior plumbing. |
| Chimney and fireplace inspection | Older masonry, regular fireplace use, visible cracking or unknown service history | The inspection level and areas viewed should be explicit; concealed flue or structural conditions may need more investigation. |
| Foundation, structural, geotechnical or drainage review | Cracking, movement, hillside location, retaining walls, drainage history or a general inspector's referral | Use the professional qualified for the actual question. A contractor estimate, engineer opinion and geotechnical investigation are not interchangeable. |
| Electrical, plumbing, HVAC or specialty-system inspection | Older or modified systems, knob-and-tube wiring, panels or equipment with known concerns, nonstandard heating or unexplained performance issues | A system review is limited to that discipline and may require permits, utility coordination or destructive access to answer every question. |
| Environmental or material-specific assessment | Known or suspected lead, asbestos, mold, soil or tank concerns, or planned work that could disturb older materials | Testing and remediation should be scoped by appropriately qualified professionals. A general home inspector may only identify a reason for referral. |
| Pool, spa, well, septic or other site-system inspection | The property contains the relevant feature or relies on a private system | Standards, permits and specialist qualifications vary; one passing test does not establish all future performance. |
| Permit and records review | Additions, conversions, ADUs, changed unit count, uncertain work history or a mismatch between the property and public records | Records research is not a physical inspection. Missing records do not prove work was never done, and an issued permit does not by itself prove final approval. |
For a condominium, the unit inspection is only one half of the condition review. The HOA's reserve study, insurance, meeting minutes, assessment history, litigation, building inspections and major-project records may reveal risks that no unit inspector can see.
How should a seller choose the inspection package?
Use this sequence instead of starting with a generic bundle:
- Profile the property. Record age, construction type, slope, drainage, systems, additions, occupancy, HOA status, repair history and known events.
- Screen legal and local requirements. Separate mandatory inspection or certificate work from optional condition research.
- Ask what decision each optional report will change. Will it define an essential repair, support pricing, reduce buyer uncertainty, identify a safety concern or clarify who should inspect next?
- Start broad only when broad is useful. A general or pest inspection can identify specialist questions; an obvious foundation, sewer or environmental issue may justify going directly to the relevant professional.
- Choose a response to each material finding. Repair it, obtain an estimate, commission specialist follow-up, disclose it and price for it, or explain why no further action is planned. Local law, safety, insurance, lender requirements or the purchase contract may narrow those choices.
- Update the disclosure file. Preserve reports and invoices and amend disclosures when a material fact changes. Do not assume a repair erases the history of the issue.
The goal is not a property with no imperfections. It is a sale plan in which the seller understands the known facts, the buyer can evaluate them, and mandatory local work is not discovered when escrow is already running.
What should a seller gather before completing forms?
Create one working file with:
- the vesting deed and any trust, estate, entity or signing-authority information;
- the year acquired and the seller's occupancy history;
- leases, notices, rent records and information about every current occupant;
- permits, plans, final approvals, invoices, warranties and improvement dates;
- past disclosures and every inspection or specialist report still available;
- insurance-loss information and repair documentation;
- utility, sewer, sidewalk, energy, seismic or other local certificates;
- HOA governing documents, budgets, reserve information, assessments, violations and building reports;
- solar, battery, security, water-treatment or other leased or financed equipment agreements; and
- a chronology of leaks, movement, drainage events, backups, repairs, neighbor issues and government notices.
Missing records should be identified as missing rather than reconstructed from memory as if certain. A careful timeline often produces a clearer disclosure than a stack of unlabeled invoices.
What should happen when an inspection finds a problem?
First, preserve the report and identify exactly what the inspector observed, what was outside the scope and what follow-up was recommended. Then decide whether the finding raises an immediate safety issue, a local compliance requirement, a specialist question or a preparation choice.
If a specialist is needed, use the appropriate discipline and give that professional the earlier report. Compare repair and current-condition sale paths using probable net proceeds, time and uncertainty—not just the highest possible price. If work is completed, keep the contract, permit, invoice, warranty and completion evidence and update the disclosures accurately.
Cosmetic work should never be used to conceal a known condition. A repaired condition may still have a material history, and the right disclosure language for a specific issue is a legal and transaction question rather than a marketing decision.
Frequently asked questions
Is a Bay Area seller required to get a general home inspection before listing?
Not as a universal statewide rule. California requires disclosures in many residential transfers, and some local programs require a particular inspection, test, report or certificate. A general pre-listing home inspection is a separate strategic choice unless the property's facts, contract or another rule make it necessary.
Is an inspection report the same as a disclosure?
No. The report communicates findings within the inspector's scope; the seller must still complete applicable disclosures and disclose other known material facts. The report should be included or referenced when required, but it does not speak for everything the seller knows.
Does the TDS replace the buyer's inspections?
No. The statutory TDS itself explains that it is not a warranty or a substitute for inspections. A buyer should investigate the property under the purchase agreement and with the appropriate professionals.
Does selling “as is” eliminate seller disclosures?
No. “As is” can affect the repair bargain, but it does not waive the TDS article where it applies or authorize concealment of known material facts. Other disclosure duties depend on the governing law and transaction facts, which should be reviewed with the transaction professionals.
Must a seller repair everything disclosed or found in an inspection?
Not automatically. Some local compliance, safety, lender, insurance or contractual requirements can require action, but many condition findings can instead be investigated, disclosed, estimated and reflected in the sale strategy. The seller should compare repair cost and time with buyer impact and probable net proceeds.
Can the buyer take responsibility for local compliance after closing?
Only when the governing program provides an approved path and its steps are followed. Oakland, EBMUD, Berkeley and San Francisco each use different certificates, agreements, deposits, deadlines and eligibility rules. A private agreement between buyer and seller does not by itself satisfy the agency.
Who pays for a sidewalk, sewer lateral or energy upgrade?
The ordinance may place the compliance obligation on an owner or property while allowing the parties to negotiate cost or future work through a prescribed process. The purchase contract, escrow instructions, HOA documents and agency rules need to align. Confirm both legal responsibility and the negotiated economic allocation.
Are probate, trust or family transfers exempt from every disclosure?
No universal exemption applies to everything. A transfer may be exempt from one California disclosure article while remaining subject to other state or federal duties, known-material-fact principles or local programs. Confirm the precise transfer and the transferor's role with a California real estate attorney and the local agency.
Does ordering a pre-listing inspection create more disclosure work?
It can. A seller should expect the report and material findings to become part of the factual record. That is not necessarily a reason to avoid useful information; it is a reason to order inspections deliberately and have a plan for specialist follow-up, repair, disclosure and pricing.
How early should local compliance be checked?
Before the listing calendar and preparation budget are fixed. Testing, repair permits, HOA coordination, agency processing and formal extensions can take time. Early screening preserves more choices even if the seller ultimately uses an approved deferral.
Professional boundary
This guide is educational real estate decision guidance, not legal, property-condition, engineering, environmental, construction, insurance or code-compliance advice. Disclosure obligations and exemptions depend on the property, parties, transfer and current law. Westin can help organize the property history, identify the agencies and specialists to contact, compare preparation paths and coordinate the transaction. A qualified California real estate attorney should confirm legal duties and exemptions; the administering city or utility should confirm local compliance; and appropriately licensed inspectors, engineers, contractors and environmental professionals should make condition conclusions within their disciplines.
