Identify the building question before choosing a resource
San Leandro distinguishes older wood-frame-home strengthening from a separate soft-story program. The page identifies workshop and Plan Set A resources and expressly says its contractor list is not an endorsement.
State what is reliably known about the building and retain any existing professional report. Mark uncertain structural features as assessment questions. Do not infer the appropriate program, method or design from an exterior photograph, the building’s general age or the fact that a resource is available online.
Keep guidance and a contractor list separate from design
Ask Building and the appropriate professional which resource fits the actual proposal. Then ask what assessment or design the proposed work would include and what remains outside it. A general repair quote should not silently become a structural retrofit package without those questions being answered.
If a contractor name came from a city resource, keep that origin separate from evidence about the actual offer. Confirm the proposed work directly and retain the basis for any design claim. No contractor qualification, building classification, resource applicability or expected seismic performance was established for this guide.
Does a San Leandro workshop resource establish the retrofit design for my building?
No building or design applicability was assessed. Use the resource to frame an enquiry with Building and an appropriate professional, without treating workshop material as a completed project design.
Does a city-provided retrofit contractor list endorse the contractor?
The city expressly says its list is not an endorsement. Ask about the actual proposed scope and supporting assessment directly; the list does not establish this guide’s verification of credentials or performance.

For a rented home, confirm who can authorize alterations. In a shared building, ask about access and work rules. A citywide construction period does not establish the age, condition or safety requirements of an individual home; check the property records and the specific project.
