ADU Construction in North Hollywood
ADUs in North Hollywood drawn so an LADBS plan checker finds the bedroom exit, alarms and separation clear, beside an older house kept as built.
The bedroom gets a close read from an LADBS plan checker on a North Hollywood ADU. The sheets have to show an egress window with an opening a grown person can pass through and a sill low enough to reach, along with smoke and carbon monoxide alarms wired to sound together. We draw that room with care, and we let the older house in front keep its porch, its siding and its street-facing windows exactly as they are.
Life safety on the sheets
Beyond the egress window, the reviewer checks that each alarm sits where the code places it, inside the sleeping room and in the hall outside it, and that the alarms are hardwired with battery backup. State ADU law says a unit needs no fire sprinklers when the main house was not required to have them, so we note the main house's status on the plans. A bath fan ducted outdoors, a strapped water heater and a pressure test on any new gas line round out what we mark before submitting.
Where the older house enters the review
The main house shows up on the plans too. Its footprint, its distance from the new unit and the walls that face it are drawn to scale, since a tight gap can call for a rated wall on the ADU side. Its electrical service is listed so the load calculation holds up. None of this asks the original house to change. Its plaster, wood windows and trim remain untouched unless a new circuit or a sewer connection has to pass through, and then we open the smallest patch that does the job.

ADU Construction in North Hollywood: common questions
We read the label inside the main panel, total the loads the unit adds, and show LADWP and the plan checker which path we chose: an upgraded main service feeding both buildings or a dedicated meter for the unit. The sewer lateral is filmed before design, so the drain route on the plans matches what is underground.
Often, if the shell can be brought up to what a dwelling needs. Plan check treats a conversion much like a new unit, so the slab, wall framing and roof are opened and inspected. A garage with sound framing keeps its footprint and walls, and one without it is rebuilt on the same spot.
We read the house before we draw. The unit picks up the slope of its roof, how far its eaves reach and the spacing of its windows at a smaller scale, and the siding on the ADU is cut to the same exposure as the boards on the house. Paint is matched from the existing trim.
