ADU Feasibility & Zoning Analysis in Malibu
Malibu controls house size citywide by a Total Development Square Footage (TDSF) sliding scale, and the entire city sits in the Coastal Zone. ZoneIQ models those rules for your Malibu parcel alongside the state-law pathways.
What ZoneIQ models in Malibu
Size & density standards
Malibu controls house size citywide by a Total Development Square Footage (TDSF) sliding scale on NET lot area (slopes ≥1:1 excluded): 17.7%×lot + 1,000 sf for the first ½ acre, +10%/+5%/+2% for higher tiers, capped at 11,172 sf (lots ≥5 ac) and floored-capped at 1,885 sf (lots ≤5,000 sf); beachfront lots are TDSF-exempt (Malibu LCP/LIP §3.6.K). Setbacks and the 18 ft base height (24/28 ft with Site Plan Review, max 2 stories) are uniform citywide formulas, NOT per-zone; the zone code only sets density (RR-1…RR-40 = acres/unit; MF ≈ 6 units/acre).
Local programs
Malibu implements the state Density Bonus (LCP/LIP §3.7, certified text caps it at 25% and applies it most-protective-of-coastal-resources; realistically only parcels allowing ≥5 units).
Overlays & constraints
The ENTIRE city is in the Coastal Zone — a Coastal Development Permit is required and the certified LCP/LIP governs (ESHA, bluff, scenic, grading overlays can further restrict). Nearly all of Malibu is VHFHSZ. Palisades-fire like-for-like rebuilds (EO N-4-25, 2025 Malibu LCP amendment) may rebuild to ~110% of prior height/bulk/area through Dec 30, 2030.
State-law pathways
On top of local zoning, ZoneIQ models the California state-law pathways that often unlock the most buildout: ADU and JADU rights (Gov. Code Ch. 13), SB9 two-unit construction and urban lot splits, the State Density Bonus (§65915), and SB79 transit-oriented development standards — each shown with its statute citation.
Malibu ADU & zoning FAQ
In most cases, yes — California ADU law applies statewide and preempts many local restrictions. ZoneIQ estimates the maximum ADU (and JADU) size on your specific Malibu lot in seconds, with the local standards and overlays that bound it, then drafts the permit-application documents.
