ADU Construction in Los Angeles
Backyard ADUs and garage conversions in Los Angeles, with plaster, trim and roofing picked to take direct sun and hard storms, drawn and permitted by us.
Light-colored cement plaster with an integral color coat, laid over a double layer of grade D building paper, is the wall we reach for on a Los Angeles ADU. It holds its color through hours of direct sun without chalking, and when a hard storm pushes rain sideways, the paper behind it carries water down and out at the weep screed. Once the City of Los Angeles signs off on our drawings, the unit goes up exactly as that set shows.
Choosing the skin, the trim and the roof
Plaster only performs as well as the openings cut into it. Every window gets pan flashing at the sill and lapped paper at the head, so any water that slips behind the finish is turned outward. Trim goes in as fiber cement or painted metal, since wood on a small unit tends to check and split after a few seasons of strong sun. Overhead we favor a light, cool-rated shingle or a reflective membrane on a low pitch, which keeps the room below from heating up through the afternoon. Low-e glass on the sunniest walls does the same work for the windows. Each choice is written onto the drawings, so the reviewer sees them and the build follows them.
From plan check to the final walk
A City of Los Angeles reviewer reading a backyard unit set checks distance from the property lines, roof height, a clear path from the street for fire access, and how the unit ties into sewer and power. We answer every correction sheet in writing, revise the drawings and resubmit until the set is approved. Once work starts, inspections run in sequence, from the footing trench and underground plumbing through framing, insulation and the final walk. We book each one as the job reaches it. If opening a wall or digging a trench turns up something unexpected, we show it to you and explain the options before anything changes.
ADU Construction in Los Angeles: questions
We answer it with a tape on site. Clearances from each property line, the space the house already uses and the route of the sewer lateral set the limits. A deep yard can take a freestanding unit at the back, while a tighter parcel may suit an attached unit or a converted garage. We stake the outline before drawing any rooms.
The package suits a backyard unit on one floor, kept within 500 square feet. On a Los Angeles submittal, the reviewer works through the site plan for each setback and utility route, then reads the energy forms, where the roof, glass and insulation we picked are recorded. Agency fees and any unusual engineering sit outside the package and are quoted on their own.
Often, when the slab and framing prove sound. We drill a small test spot in the concrete for moisture, look for cracks and check the ceiling height, then walk you through what we found before suggesting anything. The car door opening turns into a framed wall carrying a window or entry door, and the room gets insulation, a vapor retarder and new wiring.
