ADU Builder in Palisades Highlands

HOA Rules and ADUs in Palisades Highlands

Much of the Highlands is organized into associations, several of them gated. Each has CC&Rs and architectural guidelines that can cover materials, colors, roof forms, landscaping and construction hours. City Planning itself acknowledges that associations here often control design, even though the City has never adopted its own design code for single-family rebuilds.

California law limits how far an HOA can go. Since 2020, CC&Rs that prohibit or unreasonably restrict ADUs and junior ADUs on single-family lots are not enforceable. Associations can still apply reasonable design rules. We read your association's documents early and plan a submittal that respects them, so HOA approval and the City permit move in parallel.

ADUs in Planned Highlands Tract Homes

Because the Highlands was built as a planned community, many homes share similar floor plans, lot sizes and garage placements. That makes some ADU approaches repeatable. An attached garage that converts to a unit, a ground-floor bedroom wing that becomes a junior ADU, or a side yard that holds a compact detached cottage may work on many lots within the same tract.

Interior options are often the easiest to get through both the HOA and the City. Carving a junior unit of 500 square feet or less out of the house changes little on the exterior, perhaps a new door and a landing. Converting an attached garage keeps the building's footprint and roofline the same.

• Junior ADU inside the existing house
• Attached garage converted to a unit
• Compact detached cottage where yards allow
• Exterior changes kept within HOA guidelines

Building Next to Topanga State Park

The Highlands backs onto wildland, with Topanga State Park rising above it. That edge matters for fire. The neighborhood is in a Very High Fire Hazard Severity Zone, and the 2025 fire burned through much of it. Any ADU here is built with ember-resistant vents, a Class A roof, siding and decks that resist ignition, and cleared, maintained ground around the unit.

The layout of the canyon also matters during construction. Palisades Drive is the main route in and out, so deliveries, cranes and debris hauling need scheduling, especially with many neighbors rebuilding at the same time. Gated communities may have their own rules for contractor access and hours.

Who Permits ADUs in Palisades Highlands

The Highlands is within the City of Los Angeles, so LADBS issues the building permit and the City's ADU ordinance applies. Hillside rules, soils reports and grading permits come into play on sloped lots. The Fire Department reviews access and sprinklers where needed, and LADWP handles electrical and water service.

For lots affected by the fire, the City's rebuild orders allow ADUs with or before the replacement home. SB 9 is not available in the burn area, so the ADU is the way to add a second unit.
