ADU Construction in West Hollywood, Drawn for Review
West Hollywood ADUs drawn for city review of shared walls, sound and fire separation, with a compact kitchen and utility routes checked on site.
A shared wall gets close attention when the City of West Hollywood reviews an attached ADU. The drawings must show a fire-rated assembly between the two homes, sealed penetrations where pipes cross it, and an entry for the unit that does not pass through the main house. We settle that wall first, since the kitchen in the unit often backs onto it and its plumbing has to respect the rating.
Fire and sound between two homes
The separating wall is framed with staggered studs or a double wall, packed with insulation and finished with type X gypsum board on both faces. Any outlet box, pipe or duct that passes through gets a listed firestop so the rating holds. The same build quiets voices and cooking noise between neighbors under one roof. If the unit sits over a garage or under living space, the floor between them carries a matching rating. A detached unit avoids the shared wall entirely, though it brings its own clearances to the lot lines.
A kitchen that fits a compact plan
In a West Hollywood unit the kitchen often runs along the wall opposite the shared one, which keeps plumbing out of the rated assembly. A sink, a cooktop over a convection oven, and a counter-depth fridge fit in a single run, with tall cabinets at the end for pantry storage. A ducted hood exhausts through the roof or an exterior wall. We set outlets along the backsplash at a spacing that meets code, and plan task lighting under the upper cabinets so the counter is never in shadow.
ADU Construction in West Hollywood: questions to settle first
Counter length is the real measure. A compact unit can hold a sink, a 24-inch cooktop, a fridge and roughly 6 feet of prep surface, and a roomier detached design might gain a dishwasher plus an eating ledge. We draw your West Hollywood footprint at scale and fit the appliances you choose before anything else is decided.
West Hollywood reviewers study the floor plan with its fire-rated separation on an attached unit, and the site plan for clearances on a detached one. Our office draws the full set, submits it to the city and revises sheets in response to each plan check comment.
Sewer and water for an attached unit can come off the house's own lines through new branches, with a separate shutoff for the unit. A detached one typically reaches the lateral through its own buried drain. Electricity comes either through a feeder from the existing panel or a meter of its own, and the load math picks which.
