ADU and Garage Conversion Builder in Beverly Hills

California's accessory dwelling unit statute reaches charter cities as well as general law cities. Government Code section 66317 requires that a permit application for an accessory dwelling unit be considered and approved ministerially without discretionary review or a hearing, and that the permitting agency approve or deny a complete application within 60 days.

Beverly Hills applies that frame through Article 50 of its municipal code. Ministerial review of accessory dwelling units and junior accessory dwelling units occurs at building permit plan check. Discretionary review enters only where a project asks for an exception to the objective standards.

The city publishes ADU development guides by area, including guides written for the Central Area, hillside parcels, Trousdale Estates, and multi-family lots. It also runs a preapproved ADU program with plan sets already reviewed against the city's design and safety requirements. Our estimating desk reads those standards against your parcel before anyone draws a line, so the first design conversation starts from what the lot actually allows.

Plans go to the Beverly Hills Community Development Department. Our project lead assembles the whole submittal: boundary and topographic survey, architectural set, structural calculations, Title 24 energy documentation, and utility load letters where the service needs upgrading.

We hold the correction cycle. Every plan check comment comes back to our desk, gets a written response, and goes out with revised sheets attached. You are not the courier between an architect, an engineer, and a plan checker.

Inspections are scheduled against the build calendar so the framing crew is standing on site when the inspector arrives, not called back two days later. You receive a weekly written update carrying three things: permit status, the next scheduled inspection, and the work happening that week. When a review stalls, you hear the reason and the recovery plan in the same message.

Beverly Hills blocks are narrow, watched, and close together. Our crews park where the household tells us to park, stage material inside the property line, and keep the street clear for neighbors and services. Deliveries land in scheduled windows agreed in advance.

Dust control, floor protection, and daily cleanup are standing site rules on every job. The driveway is clear each evening. Debris leaves the property on a schedule instead of accumulating in view.

Our field team works in unmarked vehicles when a household asks for it, posts no lawn boards, and photographs nothing without written permission. Household staff, security details, and property managers receive the same schedule the owner receives, so nobody on the property is surprised by a delivery truck or a saw cut. Quiet, occupied-home work is a practiced discipline here, and it is priced into the schedule rather than borrowed from it.

A detached guest house carries a full kitchen and bath, its own entry, and private outdoor space, sited for sightlines from the main residence and from the neighbors.

Staff quarters sit near service access, laundry, and parking, with acoustic assemblies that separate the unit from the primary living areas. Sound isolation is a framing and insulation decision made early, not a fix applied at the end.

A junior unit is carved from existing square footage inside the house, with a separate entry and an efficiency kitchen, which makes it the lightest structural path on most lots.

Each program changes the plumbing runs, the panel load, the HVAC zoning, and the wall assemblies. Our estimating desk prices those decisions before design locks, so the scope and the investment move together and no one discovers a service upgrade after the drawings are finished.

A standing garage becomes living space once the slab, moisture barrier, headroom, insulation, and egress are handled properly. We cut and infill the vehicle door opening, frame new fenestration to the rhythm of the main elevation, insulate to current energy code, and carry the existing roofline and eave detail across the new work.

Inside, the unit receives the millwork profile, stone, plaster, hardware, and door casing of the main residence. A guest suite that reads as a converted garage is a failed project, and the difference shows up in reveals, transitions, and trim returns.

Our own finish crew handles interior and exterior painting under our Class C-33 painting and decorating classification. Color, sheen, prep standard, and coating system match the house because the same crew that knows the house applies them. Nothing about the finish schedule is handed off to an outside trade.
