Best Custom Home Builder in Los Angeles: 6 Builders to Know in 2026

The best custom home builder in Los Angeles is the one whose finished homes look like your project and whose license record holds up when you check it yourself. Six builders worth knowing in 2026 are Built to Perfection, Tyler Development, Richard Holz Inc., Corr Contemporary Homes, Patterson Custom Homes, and Arzuman Brothers. Each fits a different kind of project, whether that's a hillside estate in Beverly Hills, a contemporary home drawn by an outside architect, or a coastal build in Newport Beach.


I've been building in Los Angeles since 2001, and my first project was a tear-down and rebuild. Twenty-five years later, Built to Perfection is still family-operated, and we still handle design, 3D design, permits, and construction under one Class B license (CSLB License #837987). That makes us the fit for homeowners building on a lot they own, replacing an existing house, or rebuilding after the January 2025 fires.


Match the builder's track record to your project type, then pull up their full license record on the Contractors State License Board website before you sign anything.


How We Chose These Builders

Every builder on this list cleared three checks:

  • An active Class B General Building license on the full CSLB license detail page, checked in September 2026.

  • Custom homes as a core line of work, shown in the builder's own portfolio and service descriptions.

  • At least one record you can check outside the builder's website, such as a published project credit, a named award, an industry honor, or a BBB record.

Several well-known names didn't make it because the license detail page or the outside record didn't hold up. In September 2026, one builder showed "Expired" on the CSLB search results page, while its full detail page showed it couldn't legally take on work. Always click through.


A disclosure: I founded Built to Perfection, and we're the first entry. The list isn't ranked. Every builder, including us, is described by what it builds, where it works, and facts you can verify.


Six Builders and the Projects Each One Fits

1. Built to Perfection

Best for: Homeowners who want one family-operated firm to design and build a home on a lot they own, including tear-down and rebuild projects and fire rebuilds.

Built to Perfection is a design-build custom home builder based in Canoga Park. We build on lots homeowners already own, on bare land, and on lots where an existing house comes down first. We work from Camarillo and Moorpark east to Monrovia, and from Santa Clarita south to Newport Beach. Recent builds have ranged from Tulum-inspired modern to coastal contemporary to traditional, because the design follows the homeowner's taste. The Rawling Custom Home in Woodland Hills was completed in 2025, and we have active and recent custom builds in Altadena and Pacific Palisades.

How a custom home runs at Built to Perfection:

  • One firm from concept through final walk-through. We handle design, plan check, permits, inspections, and construction.

  • Your architect or ours. We can build from plans your architect or designer already drew, or handle the design in-house.

  • You see the house before the foundation is poured. Our 3D design process lets you walk through the finished home on a screen while changes still cost very little.

  • A dedicated project manager on every custom build. I personally visit the projects close to our office. My son, Tomer Ben-Haim, is a project manager, and co-owner Roi Yehuda leads project management.

Facts you can check:

  • CSLB License #837987, Class B General Building, active, with a $25,000 contractor bond and workers' compensation on file. Our current license record dates to 2004; the business dates to 2001. See our CSLB record.

  • BBB A+ accredited since 2016. See our BBB profile.

  • 8-time Best of Houzz Service winner (2015, 2016, 2017, 2019, 2020, 2023, 2025, and 2026). Houzz bases the Service award on a company's Houzz rating and reviews from the people who hired it.

  • IICRC Certified Firm #70224833 for fire and water damage restoration, and EPA Lead-Safe RRP Firm #LBP-F307833-1 for work on homes built before 1978. Both come up often on fire rebuild lots and older teardowns.

Built to Perfection also does kitchen and bathroom remodeling, ADUs, and fire and water damage restoration, and that's how a lot of homeowners meet us first. The same project managers and crews run our custom homes. If you're comparing custom home builders in Los Angeles, our Custom Homes page shows recent builds and how a project runs with us.



2. Tyler Development

Best for: Architect-led modern estates on difficult hillside lots.

Tyler Development (licensed as Tyler Development Corporation) builds high-end custom homes and describes its work area as running from Beverly Hills north to Montecito. The company names Ron Udall as its founder.

Facts you can check:

A 2022 project tells you what a builder can do. It doesn't tell you what they're building now, so ask which neighborhoods they're working in this year.


3. Richard Holz Inc.

Best for: Architect-designed traditional or contemporary estates on the Westside, including high-end rebuilds in Pacific Palisades.

Richard Holz Inc. builds ultra-high-end new homes and renovations in Beverly Hills, Bel-Air, Holmby Hills, Brentwood, Santa Monica, Malibu, and Pacific Palisades, according to the company. Its portfolio credits projects designed with architecture firms including RIOS and KAA Design Group.

Facts you can check:

  • CSLB License #294504, Class B, active, originally issued in 1974, with a bond and workers' compensation on file. See the CSLB record.

  • Founded in 1974. The Institute of Classical Architecture & Art says Richard Holz became a licensed architect and contractor in 1972 and started the company two years later.

  • ICAA honor. The ICAA's Southern California chapter honored Richard Holz at its 5th Annual Legacy Dinner in October 2019. The honor recognizes the person, not a specific house.


4. Corr Contemporary Homes

Best for: Contemporary homes built with an outside architect.

Corr Contemporary Homes builds high-end contemporary custom homes in Bel Air, Beverly Hills, Brentwood, Pacific Palisades, Santa Monica, and Venice. James Corr founded the company in 2007, according to the company. Its portfolio also includes some remodels.

Facts you can check:

  • CSLB License #913500, Class B, active, first issued in 2008 and reissued in 2019 when the company became an LLC. The record shows a contractor bond, a separate LLC worker bond, workers' compensation, and liability insurance. See the CSLB record.

  • Published profile. Modern Luxury profiled James Corr and the firm in April 2026.

Corr's founding year, first license, and LLC reissue are three different dates. Make sure the entity on the license matches the entity on your contract.


5. Patterson Custom Homes

Best for: Custom homes and estates in coastal Orange County.

Patterson Custom Homes (licensed as Patterson Construction Corporation) builds custom homes and luxury estates in coastal Orange County, especially Newport Beach and Corona del Mar. Andrew Patterson is the company's founder and president.

Facts you can check:

The award-winning home is in Santa Ynez, not Orange County. If you're building on the coast, ask to see comparable homes that went through coastal approvals.


6. Arzuman Brothers

Best for: Buyers who want turnkey luxury design-build or a finished spec home.

Arzuman Brothers (licensed as Arzuman Brothers Inc.) builds luxury design-build and speculative homes and runs a design center in Montrose. The company lists projects in Studio City, Sherman Oaks, Montrose, Venice, and Pacific Palisades, and says it entered the LA luxury home market in 2013.

Facts you can check:

Arzuman also builds homes to sell. Buying a finished spec home and hiring a builder to work on your own lot are two different relationships, so be clear about which one you're shopping for.

How to Choose the Best Custom Home Builder in Los Angeles

These six checks tell you whether a builder fits your project. You can run every one of them yourself, and you should run them on us too.



Check the Full CSLB License Record

Open the builder's license detail page on the CSLB website and read the whole thing. The CSLB licenses about 285,000 contractors across 45 classifications, and the classification matters as much as the license itself.

Look for:

  • Status. "Active" on the detail page, not just on the search results page.

  • Classification. A Class B General Building license covers projects that involve at least two unrelated building trades, which is what a house requires.

  • Name match. The name on the license should match the company name on your contract.

  • Expiration date, bond, and workers' comp. All three appear on the same page.

  • Complaint disclosures. If there's a disclosure link, read it.

California law restricts what the CSLB can publish, and only certain complaints and construction-related judgments reported to the board show up. A clean page doesn't mean a builder has never had a dispute. A Class B license also says nothing about whether a builder has handled a hillside lot, a coastal permit, or a fire rebuild. Permits and references answer that.


Confirm the Bond and Workers' Comp

Every licensed contractor in California must carry a $25,000 license bond, a requirement that took effect January 1, 2023. That's a legal minimum. It won't come close to covering a custom home budget if something goes wrong.

Workers' compensation matters more on a build this size. Under SB 1455, the rule requiring workers' comp from every licensee now starts January 1, 2028. Until then, a contractor with no employees can file an exemption. If a builder has one on file, ask who will actually be working on your site and how they're covered.


Pull Permit History on Homes They've Finished

This is the most useful test on the list. Ask each builder for three addresses of homes they've built from the ground up in your jurisdiction. Then look them up:

  • City of Los Angeles (including Pacific Palisades): LADBS building records and the city's PRISM portal.

  • Unincorporated LA County (including Altadena): EPIC-LA. Altadena permits run through the county, not LADBS.

  • Orange County: OC Development Services covers unincorporated areas. Incorporated cities like Newport Beach run their own permit offices.

Check the scope of work, the contractor named on the permit, the inspection history, and whether the home reached final inspection or a certificate of occupancy. An issued permit only means the work was approved to start.


Look for Homes Built on Lots Like Yours

A builder with a strong record on flat lots in the Valley may never have dealt with a hillside grading plan. A builder who does Westside estates may not know Altadena's rebuild rules. Ask for finished homes on lots like yours: same slope, same jurisdiction, same kind of approvals.


Ask Who Handles Design

Some builders only build from finished plans. Others, like Built to Perfection, can design in-house or build from your architect's plans. Get a clear answer on who draws the plans, who coordinates with the structural engineer, and who owns the changes when plan check sends comments back.


Ask Who Runs the Job Site Day to Day

Ask for the name of the project manager or superintendent who will be on your site, how often they'll be there, and how often the owner of the company visits. With a family-operated firm, you should be able to reach the people whose names are on the license.


Design-Build vs. Hiring an Architect and Builder Separately

With design-build, one company holds a single contract with you for both design and construction. The Design-Build Institute of America describes the main benefits as one point of responsibility and earlier cost feedback. With the traditional route, often called design-bid-build, you hire an architect first, then send the finished drawings out for bids from builders, as the AIA explains.



Neither method guarantees the lowest price. DBIA cites a survey in which 80% of owners said they were satisfied or very satisfied with design-build. DBIA is the industry's trade association, though, and a survey isn't a forecast for one house in LA.


Over 25 years, I've seen that most homeowners building their first house don't have an architect yet, and they're relieved to have one team answer every question from the first sketch to the final inspection. If you already have an architect, you can still hire a design-build firm. Built to Perfection can build from existing plans. Just settle early whether your architect stays your consultant or joins the builder's team, because that changes the contract. You can see how our design-build process works from first meeting to move-in.


LA Lot Rules That Affect Your Custom Home in 2026

Which builder fits depends on your lot as much as your taste. The rules below are current as of 2026.


Hillside Lots

In the City of Los Angeles, homes in designated Hillside Areas fall under the hillside rules in LAMC §12.21 C.10. They cover setbacks, how much floor area your slope allows, height, grading, and street access. There's no single size limit for every hillside lot. It depends on your parcel's zoning and a slope analysis, which is why hillside experience is worth asking about directly.


Flat R1 Lots and the Mansionization Rules

On standard R1 lots outside Hillside Areas and the Coastal Zone, the City of LA caps residential floor area at 45% of lot area under LAMC §12.08 C.5. On a 7,500 sq ft lot, that's about 3,375 sq ft. Some R1 variation zones use different numbers. Residential floor area is a code calculation, so it won't match the square footage on a real estate listing.


Fire Rebuild Lots in Pacific Palisades and Altadena

Pacific Palisades is in the City of Los Angeles. Altadena is unincorporated LA County. They run on different rules and different permit systems. Of the builders above, Richard Holz Inc., Corr, Arzuman Brothers, and Built to Perfection list Pacific Palisades as a work area, and Built to Perfection also builds in Altadena. A work area isn't a rebuild record, so ask for permits on post-fire projects.

  • Pacific Palisades: Like-for-like rebuilds are reviewed against 110% of the previous home's height and footprint, in substantially the same location, according to the City's recovery FAQ. A July 2025 executive order also streamlines zoning-compliant rebuilds in the Coastal Zone that aren't like-for-like.

  • Altadena: A like-for-like rebuild in the Eaton Fire area can grow by up to 10% or 200 sq ft, whichever is greater, according to LA County Recovers. Like-for-like projects must meet current building, fire, and health and safety codes. Other projects must meet current zoning, including the Altadena Community Standards District. Site clearance must be complete before building permits are issued.


Fire rebuilds also come with contract protections, because California law treats rebuilding a home after a declared disaster as home improvement. Under the CSLB's rebuild payment rules, that means:

  • A fixed-price contract. Time-and-materials and cost-plus contracts aren't allowed.

  • A down payment of no more than $1,000 or 10% of the contract price, whichever is less.

  • Later payments tied to completed work or delivered materials.


If a builder asks for more than that up front on a fire rebuild, walk away.


As of mid-August 2026, about 1,000 homes had started construction in the Palisades, while 35 primary residences had certificates of occupancy, according to community-compiled figures published by the Palisadian-Post. Keep that in mind when a builder tells you how fast they can finish.


Energy Code Requirements for 2026

California's 2025 Energy Code applies to permit applications filed on or after January 1, 2026. For single-family homes built to the code's standard checklist (the prescriptive path), heat pumps are the baseline for both space heating and water heating, according to the California Energy Commission. The code doesn't ban gas. A design that shows it meets the code's overall energy budget (the performance path) can take a different approach.


Fire rebuilds get an exception. Under Executive Order N-29-25, homes destroyed or badly damaged in the January 2025 LA fires can be rebuilt under the 2022 Energy Code, without the solar panel and battery requirements. Those homes still have to be built solar-ready. A builder giving you general new-construction advice on a fire lot may be missing this.


Custom Home Builder FAQs

What license does a custom home builder need in California?

A custom home builder needs a Class B General Building license from the CSLB. Check that it's active on the full license detail page and that the name matches the company on your contract.


Do I need an architect if I hire a design-build firm?

Not separately. A design-build firm provides design and construction under one contract, so you don't have to hire an architect on your own. If you already have one, many design-build firms, including Built to Perfection, can build from those plans.


How do I check a builder's permit history in Los Angeles?

Use LADBS building records or PRISM for the City of Los Angeles, EPIC-LA for unincorporated LA County, and your city's own permit office elsewhere. Ask the builder for addresses of finished homes, then confirm each one reached final inspection.


How long does it take to build a custom home in Los Angeles?

There's no honest single number. The timeline depends on how long design takes, plan check in your jurisdiction, your lot (hillside grading and coastal approvals add time), the home's size and finishes, and whether it's a fire rebuild with streamlined review. The most realistic gauge is the permit issue dates and final inspection dates on homes your builder has finished in your city.


How much does it cost to build a custom home in Los Angeles?

Cost depends on size, lot conditions, design, finishes, and jurisdiction, so any single figure would mislead you. We walk through each of those factors in our guide to the cost to build a house in Los Angeles.


Is a contractor's $25,000 bond enough protection?

No. The $25,000 license bond is the legal minimum for every California contractor, and it's small next to a custom home budget. Your contract terms, payment schedule, insurance, and the builder's track record protect you far more.


Does California's new home warranty law cover a custom home on my own lot?

Not automatically. California's SB 800 framework (Civil Code §896) applies to original construction intended to be sold as an individual home. It sets deadlines by component, from a one-year fit and finish warranty to a ten-year outer limit for most claims. Whether it applies to a home built for you on your own lot is a legal question. Get a written warranty that lists each component and its coverage period, and have an attorney review it.

If you own a lot, you're thinking about tearing down and rebuilding, or you're rebuilding after the fires, we'd like to walk your lot with you. Built to Perfection has been designing and building homes in Los Angeles since 2001, and we'll tell you plainly whether your project is a fit for us.


Schedule a free in-home consultation at (888) 955-0535 or info@builttoperfection.com. Every custom home we build includes a complimentary 3D design consultation, so you'll see the house before we break ground.
