How Long Does It Take to Get a Building Permit in San Jose in 2025?

Quick Answer: Getting a building permit in San Jose in 2025 takes 1 day to 8 weeks depending on project complexity. Simple projects (water heater replacement, electrical panel upgrade, HVAC replacement) are often permitted over-the-counter at the San José Building Division permit counter on the same day. Complex projects (room additions, ADUs, second stories) require plan check review which takes 4-8 weeks for a first review cycle. If the plan checker returns comments requiring revisions, a second review takes another 2-4 weeks. San José Building Division offers express plan check for an additional fee (typically 2x the plan check fee) that can reduce review time to 10-15 business days for eligible projects. Online permit applications via the San José Permit Center portal are accepted for most project types. Note: permit timeline starts when a COMPLETE application is submitted — incomplete submittals are rejected and restart the clock.
