Santa Ana has Orange County's best old housing stock — 1920s Craftsman and Spanish revival in Floral Park and French Park — plus dense postwar blocks with real ADU demand. Historic-district work needs design care and texture matching; that's craft we bring from LA's oldest neighborhoods.
Santa Ana pairs OC's strongest rental demand with lots that can actually hold a unit. In Floral Park and the historic districts we design ADUs to pass design review — matched rooflines, matched stucco — so the approval goes through and the neighborhood stays the reason you bought there.
We run Orange County projects in scheduled blocks from our LA base — no trip charges, same crews, same license.
ZIP codes: 92701–92707 · Serving all of Santa Ana and the surrounding Orange County.
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 the City of Santa Ana's Planning & Building Agency — including extra design review in its historic districts, which we prepare for up front. 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+ — Santa Ana 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.
