Converting a Garage Into an ADU in Citrus Heights — A Contractor's Honest Guide
A garage conversion is the ADU most Citrus Heights homeowners should price before anything else — almost always the cheapest, fastest route to a legal second unit. The walls, roof, and footings already exist, so you're finishing a building rather than raising one. But a garage was built to shelter a car, and turning it into a place someone sleeps brings local realities: the old tract slab, ceiling height on the lower 1950s ranches, the SMUD panel question, and the City counter. Here's the version we'd give a neighbor over the fence.
Why the garage is the cheap path
The reason a conversion wins on price is plain arithmetic. A detached ADU makes you pay for a brand-new foundation and a brand-new roof, and those two items alone can run $40K to $65K on a small unit. A garage conversion reuses both. You're buying interior framing, insulation, windows, finishes — not a whole new shell. For a homeowner staring at a 360 to 480 square-foot garage, that's the difference between a project that pencils and one that doesn't, and Citrus Heights is already one of the more affordable ADU markets in the region.
Citrus Heights is unusually well-suited to this. The housing stock is mostly 1950s through 1970s ranch homes and tract subdivisions — Birdcage Heights, Stock Ranch, the Sunrise Mall corridor, Mariposa, Sylvan Old Auburn Road. Those homes came with attached two-car garages on flat, modest lots, and a flat lot is a quiet gift: no stepped footings, no retaining work. Because an attached garage shares a wall and roofline with the house, it's often close to dwelling-grade in ceiling height and slab quality already, which trims the surprises.
