Why LA Homeowners Choose Hexagon

Los Angeles presents unique building challenges — hillside grading, fire-hardened construction requirements, the California Coastal Commission, and some of the longest permitting timelines in the state. Hexagon’s design-build model puts architecture, engineering, and construction under one roof so nothing falls through the cracks on complex LA projects.

Our Los Angeles Design-Build Process

Every LA project follows our five-phase process — adapted for the unique permitting and construction realities of the Los Angeles market.

1

Discovery & Feasibility

Site visit, zoning analysis, hillside ordinance review, and preliminary budget. For fire rebuilds, we also review your insurance scope and identify gaps early.

2

Architecture & Engineering

In-house architectural design, structural engineering, and 3D visualization. For hillside lots, we coordinate geotechnical reports and grading plans from the start.

3

Permitting

We manage LADBS plan check, HOA review, Coastal Commission applications, and all other approvals. LA permitting can take 6–12+ months — our experience helps avoid costly resubmittals.

4

Construction

Full construction management with licensed crews, weekly progress reports, and a dedicated project manager. Fire-hardened materials and ember-resistant assemblies for rebuild zones.

5

Final Walkthrough & Warranty

Comprehensive punch-list, final LADBS inspection, certificate of occupancy, and full builder warranty on all workmanship and materials.

Los Angeles Design-Build FAQ

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

Custom home construction in LA typically ranges from $400 to $650+ per square foot. Hillside lots in Beverly Hills or Bel Air often exceed $700/sqft due to grading, retaining walls, and extended engineering. A 4,000 sq ft luxury home might cost $1.6M to $2.6M+ in construction alone.

How long does the LADBS permitting process take?

Standard LADBS plan check takes 4–8 months for new construction. Fire rebuild permits in designated zones can be expedited to 30–90 days under current emergency provisions. Complex hillside projects or those requiring Coastal Commission review can take 12+ months.

What areas in Los Angeles does Hexagon serve?

We serve LA’s premier Westside and hillside communities including Pacific Palisades, Beverly Hills, Malibu, Brentwood, Bel Air, Santa Monica, and the Hollywood Hills. Each area has unique permitting jurisdictions and building requirements our team knows intimately.

How does the fire rebuild process work in LA?

After a wildfire, the process begins with insurance scope review, debris removal, and soils testing. We then design the new home (often with fire-hardened upgrades), submit for expedited LADBS permits, and begin construction. Most fire rebuilds take 14–20 months from design start to move-in, depending on complexity and insurance coordination.

How much does an ADU cost in Los Angeles?

ADU costs in Los Angeles range from $175,000 to $450,000+ depending on size, type, and finish level. LA’s ADU ordinance allows up to two ADUs per single-family lot in most zones, and permitting has been streamlined under recent state legislation.
