ADU Construction for Beverly Hills Homeowners
ADU construction in Beverly Hills follows state ADU law plus a local ordinance in the city's zoning code, which adds a few rules and one notable opportunity for larger lots. Simply Construction designs, permits and builds backyard ADUs, attached units and guest houses under one contract, from the site survey to final inspection. The city approves ADUs through building permit plan check rather than a public hearing, so a complete, code-checked set of plans is what keeps the project moving, and that is where we put the early effort.
Local Knowledge
Beverly Hills ADU Rules Worth Knowing
On a lot with an existing or proposed single-family house, Beverly Hills allows one ADU and one junior ADU. Single-family lots of 13,000 square feet or more can add a third unit, which the city calls an incentive ADU, of up to 800 square feet. Its floor area does not count against the lot's maximum, a real advantage in the Flats, where large houses often use most of their allowance. The tradeoff is a recorded covenant: one ADU on the property must be rented rather than owner occupied, on leases of at least one year, with no subletting or short-term rental.
Every ADU and JADU also needs an entrance separate from the main house entrance, and the units may be rented for 31 days or longer but cannot be sold apart from the main home. North of Sunset, a detached ADU is new construction in the Very High Fire Hazard Severity Zone, so ignition-resistant materials and fire access shape the design. On the flat lots of the Central Area, the harder questions are usually about utility routing, sewer connection and electrical panel capacity rather than slope.

Planning Considerations
Choosing the Right ADU Setup
Whether the incentive ADU fits your plans
The incentive ADU adds a unit and floor area that does not count against your limit, but it comes with a long-term rental commitment on one unit. That suits an owner who wants steady rental income on one-year leases. It is a poor fit if you want the space for visiting family or occasional guests. We walk through the covenant terms with you before design, so the decision is made with the facts in front of you rather than after the plans are drawn.
State law still sets the floor
The city cannot deny a qualifying ADU of at least 800 square feet with 4-foot side and rear setbacks, and a detached ADU can generally reach 1,200 square feet and 16 feet in height. Units under 750 square feet are exempt from impact fees, and the city must act on a complete application within 60 days. Those protections matter most on smaller lots, where a large main house leaves little room under local floor area limits.
Why Choose Us
Why Beverly Hills Homeowners Choose Simply Construction
Licensed, Bonded and Easy to Verify
Simply Construction inc. is a licensed California general contractor, CSLB [CSLB LICENSE # PLACEHOLDER]. State law requires a license for any job of $1,000 or more in labor and materials, and anyone can check a contractor's license, bond and workers' compensation status on the CSLB website in about a minute. We encourage every Beverly Hills homeowner to do exactly that before signing with anyone, including us.
Permits Handled With the City of Beverly Hills
Most delays on large residential projects start at the permit counter. We prepare the drawing set, coordinate structural and Title 24 energy calculations, answer plan-check comments and schedule inspections with the City of Beverly Hills, so you are not the one chasing corrections. For ADUs, state law requires the agency to act on a complete application within 60 days, and a complete, well-coordinated submittal is what starts that clock.
Built to Current California Energy Code
New homes and ADUs in California are built to the Title 24 energy code, which has required solar PV on most new single-family homes since 2020, and permit applications filed on or after January 1, 2026 fall under the 2025 Energy Code. We plan insulation, windows, mechanical systems and solar into the design from the start instead of treating compliance as a late fix.

FAQ
ADU Construction in Beverly Hills: Common Questions
How many ADUs can I build on my Beverly Hills property?
On a single-family lot, one ADU and one junior ADU are allowed. If the lot is 13,000 square feet or larger, you may add a third unit, the incentive ADU, capped at 800 square feet, as long as one ADU on the property is recorded as a long-term rental. We confirm lot area from the survey before design so the plan starts from the right number.
Can I use an ADU as a short-term rental?
No. Beverly Hills allows ADUs to be rented only for periods of 31 days or longer, and a unit tied to an incentive ADU covenant must be leased for at least a year at a time, without subletting. ADUs also cannot be sold separately from the main house. If flexible guest use matters more to you than income, we can plan around that.
What changes for an ADU on a hillside lot north of Sunset?
The unit sits in the Very High Fire Hazard Severity Zone, so exterior materials, vents and glazing must meet ignition-resistant standards, and fire department access is part of the site plan. Slopes often add retaining walls and a soils report. We gather that information before quoting, so the price reflects the actual site rather than a flat-lot assumption.
