ADUs & Room Additions
California's ADU laws changed the math for LA homeowners: an accessory dwelling unit can add rentable square footage, multigenerational space, and long-term value on a lot you already own. But it is a small building, with its own foundation, utilities, and inspections.
How It Actually Goes
Step by step, in plain language.
- 01
Feasibility and zoning check
Setbacks, lot coverage, height limits, fire access, and whether your property sits in a hillside, coastal, or historic overlay. We tell you what your lot allows before you pay for design.
- 02
Design and utility strategy
Water, sewer, gas, and electrical service all have to reach the unit. Sometimes the existing panel has capacity; sometimes it needs an upgrade. That is a budget line, and we identify it early.
- 03
Plans and permits
Stamped plans go through plan check with corrections. Standard-plan and conversion routes are often faster than new detached construction — we recommend the path that fits your goal, not the one that bills the most.
- 04
Foundation and shell
Excavation, footings, slab or raised floor, framing, roof, windows, and weatherproofing, with inspections at each stage.
- 05
Interiors and final sign-off
A full small home: kitchen, bath, HVAC, finishes. Then final inspection and certificate of occupancy so the unit is legal to live in or rent.
