- Permit timeline · San Jose
- The first round of building plan review typically takes about 20 business days, inside the state's 60-day ministerial clock. Overall project timing still depends on permitting, the one step nobody fully controls.
- Local fees · San Jose
- School and parkland impact fees do not apply to ADUs under 750 sq ft. At 750 sq ft or larger, school district and parkland fees apply, and building permit fees scale with ADU size.

We're local. Actually.
Our family-run team is based right here. Our factory sits in Salinas, 50 minutes from San Jose, and we have built across this region for years. When we say "local," we don't mean a sales rep who covers your area from somewhere else. We mean the people who design, build, and deliver your home are your neighbors.
That matters more than you'd think. When a planning department needs a clarification, we go in person. When an inspector flags something, we are there the same day. No phone tag, no road trips, no "we'll get back to you next week."
