Do you qualify for the 60-day state path?
California's Gov't Code §65852.2 forces City of Beverly to approve a compliant ADU within 60 days — no discretionary review. Answer six yes/no questions to see if your project qualifies.
- 01
Is your parcel zoned single-family or multi-family residential?
R-1, R-2, R-3, RD — most LA County residential lots qualify.
- 02
Is there an existing or proposed primary dwelling on the lot?
ADUs are accessory by definition — a primary unit must exist.
- 03
Will the ADU be ≤ 1,200 sq ft and ≤ 16 ft tall (detached)?
State law guarantees ministerial approval within these limits.
- 04
Can you meet 4-ft side and rear setbacks?
State minimum — local zoning cannot require more for state-eligible ADUs.
- 05
Will the owner occupy either the primary or the ADU?
Required only for JADUs after Jan 2025; standard ADUs are exempt.
- 06
Is the property free of HOA restrictions that prohibit ADUs?
AB 670 voids HOA bans on ADUs in SFR zones — but check CC&Rs.
Answer all six to see your path.

How these Beverly Hills numbers are derived.
Every figure on this page falls into one of three confidence tiers. We publish the method so you can pressure-test the math before signing.
- Firm
- Pulled from our last 24 months of executed contracts in the region. Quoted ranges, not single points.
- Market data
- Sourced from third-party market trackers (Zillow, Apartments.com, RentCafe) within the last 90 days.
- Modeled
- Estimated from public records, jurisdictional bulletins, and our pro-forma model. Treat as a planning band.
- a
Permit authority & plan check days
City of Beverly Hills Community Development is the issuing jurisdiction. Plan-check window of 120–180 days reflects our last twelve submittals here for code-compliant ADU sets; complex sites (hillside, historic, coastal) trend longer. Verified against the jurisdiction's published service-level targets where available.
- b
Median lot size
Modeled from LA County Assessor parcel records (APN database) for R-1 and R-2 zoned residential parcels in the Beverly Hills city limits. Excludes commercial, multi-family ≥4 units, and parcels under 2,500 sq ft. Median, not mean — large estate lots do not skew the figure.
- c
1-BR & 2-BR rents
90-day trailing median asking rent for ADU-equivalent units (detached cottages, in-law suites, garage conversions) within the Beverly Hills ZIP codes, blended across Zillow Rent Index, Apartments.com, and RentCafe. Excludes furnished short-term listings.
- d
Starting price & cost / sq ft
Firm. Averaged from our last 24 months of signed contracts for comparable scope (Beverly Hills or adjacent submarket). Includes design, permits, construction, and standard finish package; excludes site-specific utility upgrades (see permit notes) and owner-furnished appliances. Quoted from $165K.
- e
Estimated annual ROI
Modeled as (annual gross rent − operating expenses) ÷ all-in project cost. Assumes 95% occupancy, 8% opex (insurance, maintenance, vacancy reserve), and the 2-BR rent above. Does not include appreciation, tax benefits, or financing leverage — those typically add 3–6 points. Published range of 9–12% reflects floor and ceiling scenarios.

Pulled from our 5,000-answer California reference desk — filtered to permits, costs, ROI, and design calls that actually matter on Beverly Hills lots.
What does a ADU cost in Beverly Hills in 2026?
In Beverly Hills, a turnkey ADU typically starts around $165K and runs $360–$400 per square foot installed, depending on size, finish tier, and site conditions. Permit and impact fees layer $28K–$42K on top of construction, and City of Beverly Hills Community Development runs plan check 120–180 days on a clean submittal.What are the actual permit and impact fees for a ADU in Beverly Hills?
For a permitted construction scope in Beverly Hills, the City of Beverly Hills Community Development fee stack typically lands $28K–$42K all-in: plan check, building permit, school impact (when triggered), sewer capacity, and energy compliance review. The single biggest variable is utility capacity — LADWP service upgrades common on pre-1970 panels — budget 8–12 wks.What is the per-square-foot price for a ADU in Beverly Hills?
Honest 2026 pricing for a ADU in Beverly Hills runs $360–$400 installed. Smaller footprints carry a higher $/sqft because fixed costs (kitchen, bath, utility tie-ins) spread over fewer feet. Bids that come in 20% under this band almost always exclude site work, Title 24, or impact fees — ask for a line-item breakdown before you compare.How can I make a ADU in Beverly Hills cheaper without compromising quality?
Four levers actually move the number in Beverly Hills: (1) use pre-approved standard plans where the jurisdiction publishes them — cuts plan check 30–45 days and trims design fees; (2) keep the footprint rectangular — every jog adds $3K–$6K of framing and roof complexity; (3) specify workhorse-tier finishes (LG STUDIO, Bosch 500, KraftMaid) instead of paid-name luxury — same daily UX at 35% lower spend; (4) sequence ladwp service upgrades common on pre-1970 panels — budget 8–12 wks early to avoid schedule penalties.How long does a ADU permit take in Beverly Hills?
City of Beverly Hills Community Development runs plan check 120–180 days on a complete, code-conformant submittal for a ADU. First-cycle approvals depend on three things: a stamped structural set, a Title 24 energy report bound into the package, and a site plan with verified setbacks. Most slippage comes from missing one of those three on first submittal.Why do ADU permits get rejected in Beverly Hills?
In Beverly Hills, the five most common first-cycle corrections are: (1) Title 24 energy compliance not bound to the submittal, (2) site plan setback math off by inches, (3) structural calcs not stamped by a CA-licensed engineer, (4) utility load calculations missing for the panel upgrade, and (5) drainage/grading not addressed for impervious-surface adds. Fixing all five before submittal cuts 120–180 days off the schedule.Does state ADU law override Beverly Hills rules for my ADU?
For qualifying ADU and JADU scopes, California Government Code §65852.2 and §65852.22 preempt most local discretionary review — Beverly Hills cannot impose owner-occupancy requirements (banned by AB 976), most parking minimums near transit, or stylistic design review. Local jurisdictions still control building-code application, Title 24, utility connection, and impact fee schedules. Non-ADU scopes (full additions, remodels, hillside builds) remain fully under local control.Are pre-approved standard plans available in Beverly Hills for a ADU?
Where Beverly Hills has adopted a pre-approved standard ADU plan program, using one cuts plan check by 30–60 days and removes the structural review fee. For programs that exist (LADBS, San Jose, San Diego), the trade-off is that floor-plan changes void the pre-approval. Most owners are better off using a standard plan as a starting point and accepting the layout it ships with.How long does a ADU take in Beverly Hills from start to finish?
End-to-end for a ADU in Beverly Hills: feasibility + design 6–10 weeks, City of Beverly Hills Community Development plan check 120–180 days, construction 16–22 weeks, inspections + closeout 2–3 weeks. Realistic total: 9–14 months with a competent team and clean submittals. Add 6–12 weeks for ladwp service upgrades common on pre-1970 panels — budget 8–12 wks..What is the actual construction schedule for a ADU in Beverly Hills?
Once permits issue in Beverly Hills, a ADU runs roughly: mobilization 1 wk, foundation 2–3 wks, framing + dry-in 3–4 wks, MEP rough 3 wks, drywall + finish 5–7 wks, inspections + punch 2 wks. The largest single source of slippage is inspector scheduling; the second is finish-material lead time (60–90 days on premium tile, 8–12 weeks on imported windows).Is there a fast-track path for a ADU in Beverly Hills?
City of Beverly Hills Community Development doesn't run a paid fast-track for residential work, but submittal quality compresses the timeline the same way: a fully bound set with stamped structural, Title 24, and verified site plan typically clears in 120 days rather than the upper end. Express service exists at LADBS for certain scopes — confirm eligibility before paying the fee.Does weather affect ADU schedules in Beverly Hills?
Most Beverly Hills sites lose 5–10 working days a year to weather — Pacific atmospheric-river storms January–March, and red-flag wind days that pause crane work and roof tear-offs. Plan to dry-in (roof on, windows in) before December if the schedule allows; once the building is weather-tight, the finish trades run year-round.
