The short version
File online through San Jose's Permit Center. The city publishes clear checklists for common residential projects — use them as your bible. Simple trade permits clear in days; plan-reviewed projects take weeks. Current forms at sanjoseca.gov.
What needs a permit in San Jose
Standard California Building Code triggers: structural, electrical, plumbing, mechanical, roofing, additions, ADUs, decks, and remodels beyond cosmetic work. San Jose is ADU-friendly under state law, with ministerial review. Verify your project with our free permit checker.
What you'll need to submit
- Permit application — project description, valuation, contacts
- Plans per the city's checklist — San Jose publishes project-specific handouts; match yours exactly
- Structural calculations — where framing or loads change
- Title 24 energy documentation
- Contractor license + workers' comp — current and verifiable
Use the handouts. San Jose's published checklists tell you exactly what each project type needs. Filers who follow them to the letter clear review far faster than those who wing it.
The process, step by step
- Download your project's checklist. Find the handout matching your work and treat it as law.
- Build the package. Every item on the checklist, in the format requested.
- Submit online, pay fees. Track your permit number through review.
- Clear corrections in one pass. Answer everything completely — partial responses restart the clock.
- Issuance and inspections. Schedule inspections as work progresses; final inspection closes the permit.
Common San Jose gotchas
- Checklist drift. The handouts update — download fresh for every project, don't reuse last year's.
- ADU utility planning. Even ministerial ADUs need real thought on sewer, water, and electrical service routing.
- School and impact fees. Additions and ADUs can trigger fees beyond the permit itself — budget for them.
From our permit vault — San Jose
- Permit formats we see: fire permits run FIR##-#### (FIR21-710 … FIR25-0501) and newer FIRE-S3-21-011509; building permits are ##-###### (20-112503).
- What approval looks like: stamped plan sheets — sets come back as "Rev.1 Approved Stamped Drawings." Sheet order and naming (title sheet, FA sheets, calcs, equipment schedules) matter to reviewers.
- The jurisdiction trap: some San Jose addresses don't file with the City at all — they route to Santa Clara County Fire with a separate application. Filing with the wrong AHJ means starting over. We confirm the AHJ by address on every order.
- Submittal-book convention: approved fire sets follow a uniform breakdown — index, approved application, title sheet, plan sheets, calculations, equipment schedules. Build yours the same way.
