Local Knowledge

Garage conversions built around Gilroy's newer suburban tract housing

Gilroy's more recent residential growth has largely come in the form of newer suburban subdivisions with larger lots and correspondingly larger two- and three-car garages than you'd find closer to the urban core of the South Bay — a real advantage for anyone converting a garage into a full ADU, since there's simply more structure to work with. Some properties on the outer edges of town sit on larger, semi-rural parcels near the city's agricultural surroundings, where well or septic systems can come into play. We confirm your property's utility setup and garage size before finalizing a plan.

FAQ

Questions homeowners ask us

Often, yes — Gilroy's newer subdivisions tend to come with larger two- and three-car garages than denser South Bay cities. We measure your garage's actual dimensions and confirm what fits during the site walk.

A JADU stays within your garage's existing footprint, is capped at 500 square feet, and can share utilities with the main house — usually a simpler, faster permit. An ADU can be larger or detached, requires independent utilities, and has no owner-occupancy requirement.

Some properties toward the outer edges of Gilroy are, given the city's agricultural surroundings, and that changes what's involved in bringing independent utilities to a converted garage. We confirm your property's utility setup during the site walk.

Yes — we prepare the Title 24 energy calculations and CF1R documentation as part of every permit package, and manage plan check correspondence directly with the city so you're not the one interpreting correction letters.
