ADU Feasibility & Zoning Analysis in Santa Monica
Santa Monica controls residential size by parcel coverage, minimum area per unit, and daylight planes — there is no base FAR. ZoneIQ models those rules for your Santa Monica parcel and stacks the state-law pathways on top.
What ZoneIQ models in Santa Monica
Size & density standards
Santa Monica controls residential size by PARCEL COVERAGE + min-area-per-unit + daylight planes — there is NO base FAR. R1 single-family (SMMC §9.07.030, as amended 1/1/2020): 5,000 sf min parcel, 28 ft/2 stories, max coverage 45% (≈30% ground + 20% second; up to 50% one-story). R2/R3/R4 use 45–50% coverage + min-area-per-unit (2,000/1,500/1,250 sf), with a Tier-2 community-benefits density/height bump.
Local programs
Santa Monica Affordable Housing Production Program (AHPP, SMMC Ch. 9.64) and local Density Bonus (Ch. 9.22) apply on top of state law.
Overlays & constraints
R1 area overlays (North of Montana, Sunset Park, North of Wilshire, Expo/Pico) and the Ocean Park (OP1–OP4) and Coastal zones change coverage/height — confirm the parcel's overlay.
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.
Santa Monica 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 Santa Monica lot in seconds, with the local standards and overlays that bound it, then drafts the permit-application documents.
