How to sell a house in Watsonville with permit issues

1. Find out what is on record. Call the Building Division at 831-768-3050 about the address.
2. Check for open permits. Ask what would be needed to close them.

Watsonville permit fees and contacts

The Building Division sits within the Community Development Department and, according to the city, reviews all construction plans, including new construction fire prevention, for compliance with the Building and Fire Codes. The city’s ADU guide lists the Building Division email as building.permits@watsonville.gov, the Community Development email as cdd@watsonville.gov and the phone as 831-768-3050, with the Planning Division at 250 Main Street.

The city’s fiscal year 2026-27 fee schedule lists plan check for all occupancies at 67% of the building payment, and shows hourly rates for inspections and reinspections.

It also lists a base fee for a new ADU with a per-square-foot charge above 500 square feet, and an hourly charge for investigations of code violations. Fee tables change each year, so confirm the current amount for your project with the division before you rely on a figure.

If you are selling a house with an old permit that was never finaled, the practical question for the counter is what inspections remain and what they would cost.

California disclosure rules when permits are in question

Permit rules are local, but disclosure rules are statewide. Under Civil Code section 1102.1, delivery of the transfer disclosure statement cannot be waived in an as-is sale, and your duty to disclose material facts affecting value or desirability stays in place.

If you know of work done without a required permit, treat it as a material fact and raise it with your agent or escrow officer. Our California as-is and unpermitted work guide explains what as-is changes and what it does not.
