Why Us for Watsonville

We're local. Actually.

Our family-run team is based right here. Our factory sits in Salinas, 25 minutes from Watsonville, 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."

Watsonville ADU FAQ

Questions about building in Watsonville.

The answers below use Watsonville's own published ADU standards, cited to official sources. For the full rulebook with citations, see our ADU Rules Lookup, the Santa Cruz County ADU regulations guide, or the statewide California ADU laws 2026 overview.

How big can an ADU be in Watsonville?
By lot size: up to 850 sq ft (1 bedroom) on lots under 6,000 sq ft; 1,000 sq ft (2 bedrooms) under 10,000 sq ft; 1,200 sq ft (3 bedrooms) over 10,000 sq ft. Lots over 12,000 sq ft may instead build two ADUs of up to 750 sq ft each. Smaller lots may also qualify for a Junior ADU (JADU) up to 500 square feet. Our 14 models range from 405 to 1,200 square feet, and your free property analysis confirms exactly which sizes your lot allows.

What are the setback requirements in Watsonville?
4 ft interior side and rear setbacks; 20 ft front; 10 ft exterior side; 5 ft from an alley. We confirm the exact setbacks for your specific lot during the free site visit (step 3 of our process).

Do I need to add a parking space?
One space per unit or per bedroom, whichever is less; tandem on the driveway counts. Waived for conversions and for lots within a half mile of a public transit bus stop, in a historic district, or near a car-share vehicle. We verify your lot's parking situation as part of the feasibility study.

How much are Watsonville ADU permit fees?
Permit and impact fees vary by city, ADU size, and utility connections. No development impact fees for ADUs under 750 sq ft; larger ADUs pay fees proportionate to the primary home by square footage. Your project price carries a permitting budget built in, and we handle every submission for you. Exact fees are set by your city and county and are itemized in your feasibility study.

How far is your factory from Watsonville?
Our factory is in Salinas, about 25 minutes from Watsonville. We've delivered homes here and know the local conditions well.
