Sylmar has some of the biggest residential lots in Los Angeles — ranch homes, horse property, and hillside parcels along the foothills. Big lots mean real ADU and addition potential, and the slopes mean drainage, retaining, and foundations need to be done by people who build on hills all the time. We do.
Sylmar's oversized lots and horse properties fit full-size detached ADUs — up to 1,200 sq ft — without crowding the yard. The foothill parcels need slope and drainage review before plans, which we do at the free site check so the surprises come before the budget, not after.
We're based in Mission Hills, so Sylmar is home turf — walkthroughs usually happen within a couple of days.
ZIP codes: 91342 · Serving all of Sylmar and the surrounding San Fernando Valley.
A complete small home in your backyard — foundation, framing, systems, and finishes, up to 1,200 sq ft under state law.
The fastest, most affordable path to a rentable unit: foundation checks, insulation, systems, and a finish that doesn't feel like a garage.
Additions and junior units carved from existing space, with the required separate entrance and kitchen done to code.
Not every backyard building needs a full kitchen — we build casitas, studios, and offices to the same standard.
Trenching, sewer connections, panel upgrades, and meters — the part of ADU budgets everyone forgets. We price it up front.
Architectural plans, structural engineering, Title 24, and city plan check — or we build from the plans you already have.
Typical 2026 Los Angeles-area ranges including construction; plans, permits, and utility fees vary by city and site. Many owners see the unit pay for itself in 7–12 years of rent.
Permits here go through LADBS — Sylmar is City of Los Angeles, and most projects run through the Van Nuys LADBS office we visit weekly. We prepare the plans, pull the permits, and meet the inspectors — you never stand in a city line.
Turnkey garage conversions typically run $100k–$180k and detached new-build ADUs $250k–$400k+ — Sylmar sits squarely in those ranges. Utilities and site conditions move the number, which is why we start with a free site check and give you a written, line-item price.
