Local Knowledge

Garage conversions built around Los Altos's large lots and older garages

Los Altos has some of the largest single-family lots in the South Bay, but that doesn't always mean large garages — a lot of the city's original homes were built decades before the recent wave of teardown-and-rebuild projects, and their garages are often modest relative to the size of the lot around them. Los Altos also runs a design review process that pays close attention to exterior changes in its established neighborhoods. Between a smaller-than-expected garage footprint and a design review process that notices exterior changes, a Los Altos conversion benefits from being planned around the structure that's actually there rather than the scale of the surrounding lot.

FAQ

Questions homeowners ask us

It can, particularly if the exterior changes visibly. A conversion that keeps the existing footprint and appearance largely intact generally faces a lighter review than a visible 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 the home — many of the city's older properties have more modest garages than the size of the lot might suggest. We measure your garage's actual interior dimensions and confirm what realistically fits 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.
