What do Section 1 and Section 2 mean in a California pest report? In a separated structural pest report, Section I identifies visible evidence of infestation, infection or related conditions. Section II identifies conditions likely to lead to infestation or infection without visible evidence of either. Further inspection identifies an area the inspector could not adequately assess.
These are reporting categories, not a ranking of repair costs or a rule about who pays. This reference is educational information, not a pest diagnosis, structural opinion or legal advice.
What is a WDO report?
WDO means wood-destroying pests and organisms. A structural pest report records findings within that inspection's scope, including affected areas, relevant conditions and inaccessible areas. It may include recommendations. It is not a report on every building system. California Business and Professions Code 8516 governs these reports. California BPC 8516.
How do the three report categories differ?
| Report category | Meaning | What it does not establish |
|---|---|---|
| Section I, often written Section 1 | Visible evidence of active infestation or infection, or conditions resulting in or from it. | The category alone does not determine structural severity or repair cost. |
| Section II, often written Section 2 | Conditions considered likely to lead to infestation or infection, without visible evidence of either at the inspection. | It does not mean an active infestation was found. |
| Further inspection | An area could not be adequately accessed during the original inspection and cannot yet be classified as Section I or II. | It does not mean the area was examined and found clear. |
These definitions follow the Structural Pest Control Board's regulation 1991. Structural Pest Control Board: Act and regulations.
Does “dry rot” mean the wood was damaged without moisture?
No. Wood decay involves fungi and moisture. In everyday property language, “dry rot” is often used broadly for decayed wood, although the technical term describes a particular type of decay fungus. The label alone does not identify the organism, current moisture condition or extent of damage. Canadian Wood Council: Wood decay terminology.
Drywood termites are different: they are insects that live in wood and do not need contact with soil. The similarity between the words “dry rot” and “drywood” does not make them the same condition. UC IPM: Drywood termites.
Is an inspection report the same as evidence that work is complete?
No. Findings, a proposal for work and documentation of completed work serve different purposes. A reinspection addresses previously reported items and whether the recommendations were completed; it should not be mistaken for an examination of every concealed part of a building. The scope and wording of the actual document matter. California BPC 8516.
Does Section 1 automatically mean the seller pays?
No. The report's category describes a finding, not an agreement between buyer and seller. Payment and required work depend on the actual contract and any applicable lender, legal or other requirements. The classification alone settles neither question.
Professional boundary
This reference helps East Bay and San Francisco buyers and owners recognize report terminology. It does not diagnose a photograph, select treatment, estimate repairs or recommend a negotiation response. The licensed structural pest professional should explain the report's findings and limitations. Westin can help clarify the transaction vocabulary; structural and legal conclusions require the appropriately qualified professional.
