Short answer
Permit drawings often cost less than a full architecture engagement, but cheap drawings become expensive when city comments, engineering gaps, or scope ambiguity are ignored.
| Item | Planning range | Notes |
|---|---|---|
| Small remodel permit set | $2,500-$9,000+ | Depends on structural and MEP scope. |
| Garage conversion permit set | $4,500-$14,000+ | Existing conditions drive complexity. |
| Addition permit set | $8,000-$30,000+ | Engineering and planning review can raise cost. |
How to use these numbers
Treat the ranges as planning context, not a quote. Bay Area homes punish lazy assumptions: existing conditions, utilities, structural scope, planning review, and consultant needs can move the number fast.
