ADU Construction in North Hollywood
North Hollywood ADUs and garage conversions with the roof, gutters and drain lines planned as one system, then drawn, permitted and built to the approved set.
Every drop that hits the roof of a North Hollywood ADU needs an exit we picked on purpose. On a small backyard unit we often pitch a simple gable toward the long walls, hang a gutter on each eave and send both downspouts into a buried pipe that carries the flow clear of the footing. Inland weather can stay dry for months and then dump a heavy storm overnight, so that route is settled before the rooms are.
Where the runoff ends up
A gable splits the runoff between both eaves, so neither gutter has to carry the whole roof. We size the gutters for a hard burst, put outlets at the low ends and connect each downspout to smooth-wall pipe laid with steady fall toward a dispersal point, or to a curb outlet where the city permits one. Water should never pool at the slab edge, so the finished ground around the unit tips away from it. Under the roofing, a peel-and-stick membrane runs along every eave, and a kickout flashing turns water away at each spot where the eave runs past a wall. A pale roof surface also keeps the room below cooler through a hot inland afternoon.
Plan check with the City of Los Angeles
Our drawings for a North Hollywood unit go to the City of Los Angeles building department, which checks the setbacks, the height, the gap to the main house and how sewer, water and power get to the back. We submit the set, reply to each correction in writing and book inspections as the work reaches them, from footings through final. The pitch we choose for drainage has to clear the height limit on the section drawing, so the two are decided together. Before suggesting a spot, we open the sewer cleanout and look inside the panel, then go over what we found with you. Permit charges belong to the city and appear as their own figure in your written quote.
ADU Construction in North Hollywood: questions
We start with a tape and the survey. Side and rear setbacks, plus the space the code wants between the unit and the house, outline what is left. On a North Hollywood parcel we also hold room for the pipe that takes roof water out of the yard. A deep yard can fit a freestanding cottage, and a shallow one may suit an addition or a converted garage.
A City of Los Angeles reviewer looking at a North Hollywood set will trace the setbacks, the sewer route and the drain line from each downspout on our site plan, and we dimension all of it there first. It travels inside a package scoped to a single-story unit whose floor area tops out at 500 square feet.
Yes, when the concrete, the framing and the headroom check out. A conversion keeps the old garage roof, so on a North Hollywood lot we also see where its runoff drops now, whether along the driveway or toward a neighbor. We test the slab for damp, open the wall finish near the base to see the sill plate, and show you each result before pricing the work.
