Richard Rodriguez has been building in Watsonville and Santa Cruz County for over 30 years. He's worked on everything from simple garage conversions in Beach Flats to full two-story detached ADUs in the Ohlone Parkway corridor. That experience means faster permits, fewer surprises, and better outcomes for you.
Meet Richard RodriguezWatsonville's R-1 and R-2 zoning areas are well-suited for ADU construction under California's AB 68 and SB 9 laws. Many lots in Watsonville qualify for both a primary ADU and a Junior ADU (JADU), potentially adding two units to a single-family property. Peninsula Construction helps you maximize your lot's full potential.
Peninsula Construction builds all five ADU types in Watsonville. We'll help you determine which type maximizes your property's potential.
A fully separate structure in your backyard. Maximum privacy and rental value. Custom designed to your lot.
Connected to your main home but with a separate entrance. Cost-effective with shared wall construction.
The most affordable ADU path. We convert your existing garage into a fully permitted living space.
Up to 500 sq ft carved out of your existing home. Lower cost, faster permits, great for in-law suites.
Maximize square footage on smaller lots by building up. Ideal for Watsonville properties with limited yard space.
