Coastal construction, fire rebuilds, and luxury renovations along 27 miles of Malibu coastline. We navigate Coastal Commission approvals, septic engineering, and fire-hardened building requirements.
Request a Free Project AuditMalibu is one of the most complex building environments in California. Nearly every project requires California Coastal Commission review, many lots rely on septic systems rather than sewer, and wildfire risk means all new construction must meet the latest fire-hardening standards. Hexagon’s design-build model is built for exactly this kind of complexity — one team managing architecture, engineering, permitting, and construction from start to finish.
Malibu has experienced devastating wildfires including the Woolsey Fire and more recent events. We specialize in rebuilding fire-damaged homes with modern fire-hardened materials, improved defensible space, and ember-resistant assemblies — all while coordinating insurance and expedited permitting.
Oceanfront and blufftop custom homes from $450–$750+ per square foot. We manage Coastal Development Permits, geotechnical engineering for bluff-top lots, and salt-air-grade material specifications that protect your investment.
Whole-home remodels and additions for Malibu’s existing homes. Whether you’re updating a Carbon Beach cottage or renovating a Point Dume estate, our team handles design, permitting, and construction as one integrated process.
ADUs in Malibu face unique constraints including Coastal Commission review and septic capacity. We design units that maximize allowable square footage while meeting all coastal and environmental requirements.
New construction in Malibu typically ranges from $450 to $750+ per square foot. Oceanfront properties often exceed $800/sqft due to foundation requirements, salt-air materials, and extended Coastal Commission permitting. Fire rebuilds may cost less if the foundation is reusable.
The California Coastal Commission reviews most construction in Malibu’s Coastal Zone. Projects require a Coastal Development Permit (CDP), which adds 3–12+ months depending on complexity. The Commission evaluates visual impact, public access, habitat protection, and building height. Our team has extensive experience with CDP applications.
Fire rebuilds in Malibu typically take 16–24 months from design start to move-in. Expedited permitting provisions can reduce plan check to 30–90 days for like-for-like rebuilds. Projects that significantly expand or change the footprint follow the standard permitting timeline.
Most of Malibu relies on septic systems rather than municipal sewer. New construction and major remodels typically require a percolation test, septic system design by a licensed engineer, and approval from the LA County Department of Public Health. We coordinate all of this as part of our design-build process.
All new construction in Malibu’s Very High Fire Hazard Severity Zone must meet Chapter 7A fire-hardening standards: ignition-resistant roofing, tempered dual-pane windows, enclosed eaves, fire-rated exterior walls, and ember-resistant vents. We design every rebuild and new home to exceed these minimums.
