ADU Contractor in Beverly Hills, CA

Convert the garage or build a guest house?

A rear garage conversion is the faster, lower-cost path because the shell exists, though slab and framing must be brought to current code. A detached new build delivers a purpose-designed guest house or suite with better light, layout and separation — usually the right call on the larger lots. We scope both at feasibility.

Matching the architecture

Beverly Hills homes carry strong architectural identities — Spanish Revival, Tudor, Georgian, mid-century. Roof pitch, window proportions and exterior materials that match the primary residence keep the property cohesive and protect its value; we design the ADU as part of the estate, not an addition to it.

Utilities and sewer

The sewer route and depth, the capacity of the main electrical panel and whether the ADU gets its own meter are decided during feasibility, because they shape both the design and the estimate. A detached unit usually needs a new sewer connection or a tie-in to the main house lateral, a subpanel or panel upgrade, and its own water and gas planning.

Family, staff or rental use

State ADU law allows a permitted ADU to be rented long-term; short-term rentals are more restricted. A unit for family or staff differs from a rental in accessibility, sound separation, private entry and metering. We design for the stated use from the start, and we confirm the city’s current rental rules for your parcel.

• Beverly Hills is its own city — permits are issued by the City of Beverly Hills Community Development Department, Building & Safety, not LADBS. The city applies state ADU law through its own municipal code and publishes its ADU standards on its own pages.
• California ADU law applies statewide: qualifying ADUs are approved ministerially — no discretionary hearing — and a complete application must be approved or denied within 60 days. State law guarantees at least an 850-square-foot one-bedroom or 1,000-square-foot two-bedroom ADU with 4-foot side and rear setbacks, and 16-foot height for a detached unit. The California HCD ADU Handbook is the authoritative plain-language reference; local standards still shape design, so we confirm them with the city for every parcel.
• Hillside parcels north of Santa Monica Boulevard can sit in mapped fire hazard severity zones and carry grading, access and ignition-resistant construction requirements. Historic or architecturally significant properties may add design-review considerations. All of this is assessed at feasibility, not discovered at plan check.
• We prepare the drawings, submit to the city, respond to plan-check corrections and schedule every inspection. Requirements change; we confirm them with the city on every project.

Timeline

Feasibility and design take a few weeks; city plan check follows and varies with the design and season. A garage conversion is typically the fastest build; a detached new-construction ADU takes several months of construction. You receive a written schedule and a single point of contact from the first visit to the certificate of occupancy.
