Record the drawing title and version used for the proposal
San Mateo’s forms index lists Brace and Bolt Standard Plan Set A for residential seismic strengthening. The listing identifies a resource; this update did not review the drawing body or select a design.
Ask the assessor to identify the actual drawing title, version or date, and proposal reference used in the assessment. Keep those identifiers together in the project notes. A file saved under a similar name should not silently replace the document the assessor identified.
Track product and proposal changes against that record
When discussing proposed items, retain the exact product or model references used in the assessed proposal. Ask the responsible assessor how those items relate to the recorded drawing version. This is a reference question, rather than a reason to create a hardware list from an index title.
If a product or the proposal changes, identify the change explicitly. Seek updated assessment and scope authorization from the relevant parties before relying on the earlier record. Keep the revised product and proposal references with the corresponding drawing version so the handoff shows what was actually considered.
What drawing reference should stay with a San Mateo retrofit proposal?
Keep the actual drawing title, version or date, and proposal reference identified by the assessor. If only an index link is known, ask which document the assessment uses rather than select it here.
What if the proposed product or scope changes after assessment?
Explain what changed and ask the relevant parties for updated assessment and scope authorization. Keep the revised product and proposal references attached to the corresponding drawing version instead of assuming the earlier record covers the change.

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.
