Garage-to-JADU, garage-to-ADU, home office and in-law suite conversions in Cupertino — permitted, Title 24 compliant, and drawn against the city's strict R-1 design standards.
Cupertino runs one of the more particular plan check and design review processes in the Bay Area — its R-1 single-family zoning comes with detailed standards on setbacks, height and neighborhood compatibility, and reviewers hold exterior changes to them closely, even on a project as contained as a garage conversion. Parts of Cupertino also sit on hillside terrain, which brings grading and drainage into the picture on top of the base R-1 rules. Many Cupertino garages are also on the smaller, older side relative to the size of the homes around them, since additions over the decades often expanded the house without touching the garage. We draw against Cupertino's actual review standards and your garage's real dimensions, not a generic R-1 assumption.

It can, particularly if the exterior of the garage changes — new windows, a different roofline, or visible utility additions. A conversion that keeps the existing exterior largely intact usually faces a lighter review than an addition would, but we confirm what your specific project will trigger before we design it.
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.
It depends on project scope and whether design review is triggered — a straightforward interior conversion generally moves faster than one that changes the garage's exterior appearance. We can't promise the city's timeline, but drawings prepared against Cupertino's actual standards are the biggest lever on how many correction cycles you go through.
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.
