ADU builders in South Gate

South Gate is dense, hardworking, and family-first: 1920s–50s stucco homes, a rear garage on almost every lot, and households where three generations share one address. Permitted garage conversions and honest repairs protect exactly what these homes are for their families — the wealth.

Why South Gate homes bring this work to us

South Gate's lots are compact but nearly all have a rear garage — and the city checks setbacks and legality closely, which is exactly why conversions here must be permitted. Done right, a South Gate garage becomes housing for family or $1,800+ in monthly rent.

South Gate is a straight run down the freeway from our Valley shop — we schedule South LA work in efficient blocks, with no trip charges.

What's included

ADUs we build in South Gate

Detached new-build ADUs

A complete small home in your backyard — foundation, framing, systems, and finishes, up to 1,200 sq ft under state law.

Garage conversions

The fastest, most affordable path to a rentable unit: foundation checks, insulation, systems, and a finish that doesn't feel like a garage.

Attached ADUs & JADUs

Additions and junior units carved from existing space, with the required separate entrance and kitchen done to code.

Guest houses & casitas

Not every backyard building needs a full kitchen — we build casitas, studios, and offices to the same standard.

Site work & utilities

Trenching, sewer connections, panel upgrades, and meters — the part of ADU budgets everyone forgets. We price it up front.

Plans, engineering & permits

Architectural plans, structural engineering, Title 24, and city plan check — or we build from the plans you already have.
