West Hollywood ADU permits — what plan-check really looks like
Every West Hollywood ADU permit runs through City of West Hollywood Building & Safety. This is the realistic, project-manager view of that process — submittal package, plan-check rounds, the comments that come back most often, fees that hit before construction, and what separates a first-pass approval from a five-month round trip.

City of West Hollywood Building & Safety submittal package
A clean first submittal in West Hollywood includes: site plan with setbacks and FAR calculation, architectural set (floor plans, elevations, sections, roof plan), Title 24 energy compliance, structural calcs and details, MEP plans, and the ADU-specific application packet. Missing any one of these adds two to four weeks of plan-check delay — not because plan-check is slow, but because the package goes back to the design team.
First-pass comments — the predictable ones
West Hollywood plan-checkers consistently flag the same items: setback dimensioning, fire-separation details where the ADU is close to the main house, parking math (or its waiver), egress window sizing, Title 24 documentation gaps, and missing structural connection details. A disciplined design set anticipates these. Most second-pass turnarounds are avoidable.
Fees, school fees, and utility connections
Plan-check fee, building permit, mechanical/electrical/plumbing permits, school district impact fee (if applicable), water capacity fee, and sewer capacity fee. In West Hollywood, these collectively land between $14,000 and $28,000 depending on ADU size and existing utilities. We model this at feasibility so the homeowner sees a real total, not just construction cost.
How long it actually takes in this jurisdiction
City of West Hollywood Building & Safety plan-check averages 3–5 months from submittal to permit issuance in 2026 — assuming a clean package and responsive comments. Hillside, coastal, HPOZ, or special review overlays add 4–10 weeks. We tell the homeowner the realistic window at feasibility, then track it weekly.

Questions West Hollywood homeowners ask about permits
Direct answers, West Hollywood-specific.
Does WeHo allow ADUs on RSO buildings?
Yes — state law overrides local prohibitions. RSO status on the main house is preserved; the new ADU itself is not automatically RSO.Why is WeHo permitting longer than LA City?
Design review and a smaller department add weeks. The trade-off is a more predictable inspection cadence once permits issue.Does West Hollywood have unique requirements that affect permits?
Yes — City of West Hollywood Building & Safety sets the local rules, and West Hollywood has its own plan-check rhythm. The realistic numbers above reflect 2026 West Hollywood conditions, not statewide averages.
