Gilroy sits at the southern gateway to Silicon Valley, making it an increasingly popular bedroom community for tech workers priced out of San Jose and Morgan Hill. That commuter demand drives strong rental rates — and a well-built ADU in Gilroy can generate $2,000–$2,800/month in rental income.
Peninsula Construction brings its Central Coast expertise to Gilroy and Santa Clara County. We understand Gilroy's permit process and zoning codes, and our full-process approach means you don't need to coordinate between multiple contractors.
Meet Richard RodriguezGilroy has implemented California's ADU streamlining ordinance. Many Gilroy properties — especially larger lots in newer subdivisions — are excellent candidates for detached ADUs. Peninsula Construction offers a free property evaluation to determine your lot's ADU potential.
Peninsula Construction builds all five ADU types in Gilroy. 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 Gilroy properties with limited yard space.
