Building in San Jose & Willow Glen

San Jose reviews plans in-house, so the queue can be long, but the city offers fast tracks: one-story additions under 500 sq ft can qualify for same-day Residential Express permits, and ADUs have their own dedicated service. For single-family homes, going above about 45% floor area ratio triggers an extra Single-Family House Permit, so we size additions with that line in mind.

Questions San Jose & Willow Glen homeowners ask

Can I get a fast permit for a small addition in San Jose?

Possibly. San Jose’s Residential Express service can issue same-day permits for one-story additions under 500 sq ft. Larger additions go through regular plan review, which runs in 30-day cycles.

How big can my San Jose addition be?

Single-family homes up to about 45% of the lot area get standard review. Above that, the city requires an additional Single-Family House Permit. Setbacks, height limits and easements also shape the final size.

Can you convert an attic into living space?

Yes. In Willow Glen we turned an attic into a primary suite, bath and art studio, raised a gable for headroom and built a custom enclosed spiral staircase.
