SF DBI Inspections: What Happens During a Building Inspection
By Solid Bay Construction SF | Updated 2026
Your permit is approved and construction is underway — now DBI inspectors verify the work matches approved plans and current code, at specific points throughout the project. Here's what actually happens at each visit.
The Typical Inspection Sequence
- Foundation / rebar inspection — before concrete is poured, verifying rebar placement and forms match approved structural plans
- Rough framing inspection — after framing but before drywall, checking structural connections, hold-downs, and dimensions against plans
- Rough electrical, plumbing, and mechanical — after wiring, pipes, and ductwork are run but before they're covered, verifying code compliance (often scheduled as separate visits)
- Insulation inspection — confirming insulation type and R-value meets Title 24 energy code before drywall closes the walls
- Final inspection — after all work is complete, verifying the finished project matches approved plans and all prior corrections were made
How to Prepare for an Inspection
- Have the approved plan set on site and accessible to the inspector
- Make sure the specific area being inspected is actually accessible — not blocked by materials or other trades' work
- Have your contractor or a knowledgeable representative present to answer questions
- Address any items noted at a prior inspection before scheduling the next one
What Happens If You Fail an Inspection
Failing an inspection isn't unusual and isn't a permit denial — the inspector documents specific corrections needed, and you schedule a re-inspection once they're addressed. The real cost is time: each re-inspection cycle typically adds several days to a week to the schedule, which is why experienced contractors prepare thoroughly rather than treating inspections as a formality.
Same-Day vs. Scheduled Inspections
SF DBI inspections are typically requested online or by phone the day before, with a general morning or afternoon arrival window rather than an exact time — plan for some flexibility in your schedule on inspection days.
