Home Remodeling Contractor in Los Angeles

Apex Build plans and builds whole-house and multi-room renovations for Los Angeles homeowners, from a phased whole-home refresh to a full gut renovation. If you're renovating a single kitchen or bathroom, our kitchen remodeling and bathroom remodeling pages cover that scope directly. This page is for projects that touch multiple rooms or the whole house at once.

What's included in a whole-home remodel

A whole-home remodel with Apex Build can include any combination of:

• Multi-room and whole-house interior renovation

• Gut renovations down to the studs, including new systems

• Structural work: wall removal, reconfigured floor plans, additions coordinated with our room addition team

• Non-structural updates: flooring, finishes, fixtures, paint, cabinetry

• Electrical, plumbing, and HVAC upgrades tied to the remodel scope

• Design and permit management, including Title 24 energy compliance documentation for permitted work

• Single-room kitchen or bathroom work handled through our dedicated kitchen remodeling and bathroom remodeling pages when that's the full scope

• Ground-up rebuilds handled through our new construction team when a project goes beyond renovation

Our whole-home remodeling process

1. Consultation and walkthrough. We look at the space, talk through your goals and budget, and scope whether the project is cosmetic, mid-range, or a full gut renovation.

2. Design and scope definition. We finalize layout, finishes, and which rooms or systems are in scope, including any structural changes.

3. Permitting. For work in the City of Los Angeles, we prepare and submit the permits your scope requires through LADBS. Cosmetic-only work (paint, fixtures, hardware) typically doesn't need a permit. Structural, electrical, plumbing, or HVAC work does. Projects outside the City of Los Angeles go through that city's own building department, since Santa Monica, Pasadena, Beverly Hills, West Hollywood, Glendale, Long Beach, and Calabasas each run separate permitting offices, not LADBS.

4. Construction. Our crews build to the approved plans, with scheduled check-ins so you know what's happening room by room.

5. Inspections and walkthrough. We coordinate required inspections as work closes out, then walk the finished space with you before sign-off.

What does a whole-house remodel cost in Los Angeles?

Cost scales with how much of the house you're touching and how deep the work goes. Based on NPLine Design's Los Angeles renovation cost data, full home renovations in LA run $200 to $800+ per square foot overall, broken down by scope:

Sweeten's Los Angeles cost-per-square-foot research puts the broader range at $125-$500+ per square foot, and breaks it down by room type: dry rooms like bedrooms and living rooms run closer to $100/sf, while wet rooms like kitchens and bathrooms run closer to $400/sf because of the plumbing and electrical work involved. As a real-world reference point, a 2,000 sqft gut renovation, new kitchen, bathrooms, flooring, and systems, typically lands between $300,000 and $550,000 including permits and design.

These are starting ranges, not quotes. Your actual number depends on the condition of the existing structure, the finishes you choose, and how much of the home is in scope. Get a project-specific number with a Free Estimate.

How long does a whole-house remodel take?

Timeline tracks scope the same way cost does. Per NPLine Design's project data:

• Cosmetic refresh: 2-3 months

• Mid-range renovation: 3-6 months

• Gut renovation: 6-12 months

• Addition combined with structural work: 8-14 months

• Design and permitting (pre-construction): adds 2-4 months before construction starts

Looking at the full arc from first design meeting to move-in, a four-phase timeline breakdown for large-scale LA renovations puts a complete project at 4 to 9 months from permit issuance to completion, or 24 to 60 weeks across four phases: design (5-9 weeks), pre-construction (4-10 weeks), construction (12-37 weeks), and post-construction (3-4 weeks). Larger or more structurally complex projects sit at the longer end of every range.

Do I need a permit for a home remodel in Los Angeles?

It depends on what you're changing, not just how big the project is. This section covers City of Los Angeles rules specifically; if your property sits in another incorporated city, that city's own building department sets the rules, not LADBS.

Generally no permit needed: Cosmetic-only updates, paint, new fixtures, hardware swaps, typically don't require a permit in the City of Los Angeles.

Express Permit (fast, no plan check): LADBS's Express Permit path covers straightforward work that replaces existing equipment without changing the home's structural footprint, a water heater swap or HVAC replacement, for example. These can often get a same-day permit with no plan check.

Full Plan Check required: Anything that changes how the home is supported or laid out, moving or removing a load-bearing wall, adding square footage, reconfiguring the floor plan, requires the full LADBS Plan Check process. Per LADBS's official plan check and building permit page, that process can take anywhere from a few weeks to several months depending on complexity. For structural, electrical, plumbing, or HVAC work specifically, plan check typically runs 4-12 weeks and requires PE-stamped structural engineering plans plus current Title 24 energy compliance documentation.

Non-structural work can still need a permit. Adding outlets for a kitchen island or replacing a water heater doesn't touch structure, but it does touch electrical or plumbing safety systems, which still triggers its own permit.

One more rule worth knowing: under California's Existing Building Code, if renovation work affects 50% or more of a building's work area, current code compliance can be required for the whole structure, not just the section you're renovating. This is worth flagging early if you're planning a large gut renovation.

Apex Build handles permit prep and submittal as part of the project, so you're not tracking LADBS paperwork on top of the build itself.

Can I live in my home during the renovation?

Often, yes, for partial remodels. If the project covers one or two rooms, or spaces you're not using day to day, most homeowners stay in place. Per guidance on living on-site during a renovation, staying safely in the home during construction generally requires sealed dust barriers with locking doors, HEPA filtration, and at least one usable kitchen, bathroom, and bedroom maintained throughout.

Projects that touch most or all of the house are a different story. Full gut renovations typically mean relocating for roughly 4-8 months, or living in completed sections while the rest of the house is finished in phases. We'll talk through what's realistic for your specific scope before construction starts, so there are no surprises mid-project.

Why homeowners choose Apex Build

Design, permitting, and construction run through one team on a whole-home project, so scope and schedule don't get lost between handoffs.

We know the difference between an LADBS Express Permit and a full Plan Check for City of Los Angeles projects, and we scope your project against the right one from the start. For projects in other cities within our service area, we work within that city's own building department process instead.

This is a dedicated team for multi-room and whole-house work, not a kitchen crew stretched to cover a bigger job. If your project is a single kitchen or bath, our kitchen remodeling and bathroom remodeling teams are built for that scope.

You get real cost and timeline ranges tied to your actual project up front, not a placeholder number that changes once demo starts.

Whole-home remodeling in California generally calls for a Class B General Building Contractor license for framing or multi-trade structural work, or the newer B-2 Residential Remodeling classification for multi-trade interior remodel work that doesn't involve a structural addition, per CSLB's official license classification library.

Areas we serve

Apex Build takes on whole-home and multi-room remodeling projects across the City of Los Angeles and surrounding Los Angeles County communities, including areas such as Santa Monica, Pasadena, Encino, Calabasas, Beverly Hills, West Hollywood, Studio City, Glendale, and Long Beach.

A quick note on permits: the LADBS-specific process described above applies to projects inside the City of Los Angeles. Santa Monica, Pasadena, Beverly Hills, West Hollywood, Glendale, Long Beach, and Calabasas are each their own incorporated city with a separate building and planning department. We work within whichever jurisdiction your property falls under.
