Can You Really Build an ADU in Beverly Hills?
The short answer: yes. The longer answer is more nuanced, but the bottom line is that California's statewide ADU laws apply to Beverly Hills just like every other city in the state. While Beverly Hills has historically been one of the more restrictive cities when it comes to new development, the state legislature has made it clear that ADUs are a right — not a privilege — for California homeowners.
Beverly Hills has had to update its local ordinances to comply with state ADU law, and while the city may still have certain design standards and review processes, they cannot prevent you from building a code-compliant ADU on your property.
Beverly Hills ADU Regulations
Beverly Hills follows the baseline California ADU rules, which include:
- Eligible properties: All single-family residential properties can build at least one ADU and one Junior ADU (JADU).
- Maximum size: Detached ADUs up to 1,200 square feet. Attached ADUs up to 50% of the existing home's floor area or 1,200 square feet, whichever is less.
- Setbacks: State law limits rear and side setbacks to 4 feet. Beverly Hills cannot impose greater setbacks for ADUs.
- Height: Up to 16 feet for detached ADUs under state law. Taller structures may be permitted near transit.
- Lot coverage: State law ensures you can build at least an 800 square foot ADU regardless of local lot coverage limits.
- Parking: No additional parking required for most ADUs, including all garage conversions.
- Ministerial approval: ADU permits must be processed ministerially (no discretionary review, no public hearings, no design review board approval required) as long as the project meets objective standards.
That last point is critical. Beverly Hills has a robust architectural review process for most construction, but for ADUs, the city must approve compliant projects without subjective design review. The city can require objective design standards (matching exterior materials, for example) but cannot use subjective criteria to deny or delay your ADU.
Beverly Hills Lot Sizes
Beverly Hills is known for its large lots, which is excellent news for ADU construction:
- The Flats (south of Sunset): Lots typically range from 7,000 to 12,000+ square feet. These generous lots can easily accommodate large detached ADUs.
- Trousdale Estates: Lots of 10,000–20,000+ square feet with significant elevation changes. Hillside construction adds complexity but the lot sizes are more than adequate.
- North of Sunset (Hillside area): Large, irregularly shaped lots on hillside terrain. Engineering requirements are more extensive but the space is available.
- Southeast Beverly Hills: Slightly smaller lots (6,000–8,000 square feet) but still very workable for ADU construction.
The bottom line: lot size is rarely a constraint in Beverly Hills. Most properties have more than enough room for a detached ADU.
Unique Considerations for Beverly Hills
Design Expectations: While the city cannot subject your ADU to discretionary design review, Beverly Hills does have objective design standards. Your ADU should use exterior materials and colors compatible with the primary residence. This isn't a hardship — a well-designed ADU that complements the main home actually increases property value more.
Construction Quality: Beverly Hills homeowners typically expect (and should invest in) higher-end finishes. A luxury ADU in Beverly Hills with high-quality appliances, premium flooring, designer fixtures, and thoughtful landscaping will command premium rents and maximize property value gains.
Historic Districts: Some Beverly Hills properties may be in or near historic districts. While this doesn't prevent ADU construction, there may be additional objective design standards related to street-facing facades.
Homeowner Associations: Beverly Hills doesn't have typical HOAs, but some neighborhoods have CC&Rs (Covenants, Conditions & Restrictions). Under California law (AB 68, Civil Code Section 4751), HOAs and CC&Rs cannot prohibit or unreasonably restrict ADU construction.
Permit Process
Beverly Hills processes ADU permits through its Community Development Department:
- Pre-application inquiry: Contact the Building & Safety Division to discuss your property and proposed ADU.
- Plan submittal: Submit complete construction documents.
- Plan review: The city must complete review within 60 days per state law.
- Corrections: Address any plan check comments and resubmit.
- Permit issuance: Pay applicable fees and receive your building permit.
Beverly Hills has historically been thorough in its plan review, but state law's 60-day mandate keeps the process on track. Working with an experienced ADU builder who knows Beverly Hills' specific requirements can help avoid unnecessary delays.
Construction Costs
Beverly Hills ADU construction costs are at the higher end of the LA County spectrum due to:
- Higher expectations for design and finish quality
- More complex lots (especially hillside properties)
- Premium material selections
- More stringent (though objective) design standards
Typical cost ranges:
- Garage conversions: a property-specific written estimate
- New construction (detached): a property-specific written estimate
- Junior ADUs: a property-specific written estimate
- Luxury/high-end ADUs: a property-specific written estimate
While these costs are higher than average, Beverly Hills' rental market and property values more than compensate.
Rental Income Potential
Beverly Hills commands some of the highest rents in all of Southern California:
- Studio/guest house (400–600 sq ft): $2,500–$3,500/month
- 1-bedroom (600–800 sq ft): $3,000–$4,500/month
- 2-bedroom (800–1,200 sq ft): $4,000–$6,000/month
A well-designed one-bedroom ADU in Beverly Hills renting for $3,500/month generates $42,000 annually. Compare that income, financing, operating expenses, and the property-specific written estimate to evaluate payback for the property.
Property Value Impact
In Beverly Hills, where median home values exceed $3 million, a permitted ADU can add $300,000–$600,000 in property value. This makes ADU construction one of the highest-ROI home improvements available, particularly since the ADU also generates ongoing rental income.
Who Rents ADUs in Beverly Hills?
The Beverly Hills ADU rental market attracts a unique tenant profile:
- Entertainment industry professionals: Writers, producers, and crew who want to live near studios and agencies
- Personal assistants and household staff: Many Beverly Hills homeowners build ADUs specifically for live-in help
- Graduate students: Near UCLA and other institutions
- Visiting professionals: Short-to-medium-term tenants in the entertainment, legal, and medical fields
- Family members: Many homeowners build ADUs for aging parents or adult children
Common ADU Types in Beverly Hills
Pool house conversions: Many Beverly Hills properties have existing pool houses or cabanas that can be converted to ADUs. These projects leverage existing structures and can be completed relatively quickly.
Detached guest houses: New construction detached ADUs are the most common type, taking advantage of large lot sizes.
Garage conversions: Converting a garage or carriage house into a living unit is efficient and cost-effective. Many Beverly Hills properties have oversized garages with excellent conversion potential.
Above-garage ADUs: Building a new living unit above an existing or new garage is a space-efficient option that preserves the garage function.
