Whole-Home Remodeling in Brentwood, Los Angeles

Whole-home projects span a wide range because a coordinated multi-room update and a full gut renovation with structural and systems work are fundamentally different scopes, and the Brentwood and Westside market runs well above national averages for both. Finish level, the amount of structural change, hillside grading needs and Title 24 energy upgrades all move the number substantially. We build one detailed scope and a fixed written estimate after a full-house survey, so a project this size is grounded in a single number rather than an open-ended per-room guess.

A full gut renovation typically runs four to nine months or more of construction, while a coordinated multi-room remodel can run shorter depending on how much structure moves. Before construction starts, design and LADBS permitting can add several weeks to a few months, and that phase is often the least predictable part of a project this size — especially on a hillside lot that triggers grading review. We lay out the full phased timeline alongside the fixed estimate so nothing about the schedule is a surprise.

Yes. Brentwood is a City of Los Angeles neighborhood, so any substantial whole-home remodel — moving walls, altering systems, adding square footage — goes through LA Department of Building and Safety plan check under the LA Municipal Code and the California Building Standards Code (Title 24). Hillside lots in Mandeville, Sullivan or Kenter Canyon add grading and Very High Fire Hazard Severity Zone review on top of the standard permit. We prepare and carry that full permit package as part of the job.

Title 24 is California's Building Standards Code, and its energy provisions apply to additions and to many alterations, so a substantial whole-home remodel in Brentwood commonly triggers upgrades to insulation, windows and heating and cooling to the current standard. Because a full remodel opens the walls anyway, it's the most cost-effective moment to bring the whole envelope up to code rather than doing it piecemeal later. CALGreen, the state's green building code, applies alongside it on qualifying scopes, and we document both as part of the permit submittal.

Many Brentwood hillside homes up Mandeville, Sullivan and Kenter Canyon sit in a Very High Fire Hazard Severity Zone, which brings Chapter 7A wildland-urban-interface fire-hardening requirements into scope on a substantial remodel — non-combustible roofing, ember-resistant venting and hardened siding details, among others. A whole-house project is often the practical moment to complete this work, since exterior walls and roofing are already being opened up. We confirm your parcel's fire-zone status and scope the fire-hardening detail during design.

Yes, and a full-house project is a natural moment to plan one in, since California's ADU laws (A.B. 2299 and S.B. 1069, and later legislation) preempt local zoning to allow accessory dwelling units on most residential lots. Los Angeles saw ADU permits climb from under 100 in 2016 to more than 7,000 by 2022 as a direct result. We coordinate ADU planning with the main house's systems and permitting so both move through LADBS together rather than as two disconnected projects.

Opening a compartmentalized Brentwood Tudor, Cape Cod or Spanish Revival floor plan into a connected space is the single most common whole-house request, and it's a structural project rather than a cosmetic one. Bearing walls have to be identified, beams sized and engineered to carry the loads those walls held, and the resulting posts and footings detailed to carry weight safely to the ground — especially important on California's high-seismic coast. We work all of this out on paper during design, before any wall comes down.

For a full gut renovation, most homeowners move out, because the house is taken back to the studs and there's no practical way to occupy it safely during that phase. A phased multi-room remodel can sometimes allow staying, by sequencing work zone by zone through the house, though it's genuinely disruptive. We talk through the realistic option for your specific scope honestly at the consultation, since planning for it properly matters more than a comfortable answer.

Design-build means one company handles both the design and the construction under a single contract, instead of you coordinating a separate designer and a separate contractor who then have to reconcile each other's decisions mid-project. On a whole-house remodel, where dozens of trades and decisions have to line up in sequence, that single point of accountability is the difference between one coordinated result and a stack of disconnected jobs. It also keeps design choices grounded in what the fixed estimate can actually deliver.

Hillside lots up Mandeville, Sullivan and Kenter Canyon fall under LA's hillside and grading regulations in addition to the standard building code, which can add engineering review for drainage, retaining structures and foundation work on a full remodel. Access for equipment and material staging is also tighter on a winding canyon street than on a flat lot. We scope these factors into both the design and the schedule from the first consultation, rather than treating them as change orders once construction starts.

Yes, and a full-house project is the ideal point to do it, since the home is already open and features can be designed in rather than retrofitted awkwardly later. Step-free showers, wider hallway and doorway clearances, comfort-height fixtures and solid in-wall blocking for future grab bars are all planned during design. Building these in during a renovation you're already doing is far more economical than adding them room by room down the line.

Yes — we run full-house projects across Bel-Air, Westwood and Pacific Palisades as well as Brentwood. All four are City of Los Angeles neighborhoods permitted through LADBS, though each carries its own overlay: Bel-Air and the Brentwood canyons share hillside and fire-zone rules, Westwood's Holmby Hills estates and Wilshire-corridor condos add HOA layers on stacked-unit buildings, and Pacific Palisades adds Coastal Zone permitting plus its own post-fire rebuild considerations. Wherever your home sits, we scope the project as one coordinated whole — call (424) 369-0310 to start.
