Topanga permitting at a glance

Most single-family and many multifamily properties in Topanga can qualify for an ADU, depending on site specifics. Key factors typically include setbacks, height limits, lot coverage, utility connections (including shared septic systems), and parking requirements. Some parcels also fall within Hillside, WUI (Wildland-Urban Interface), or Coastal Zone designations, where additional reviews for grading, tree protection, fire access, drainage, and building materials may apply.

Our feasibility review evaluates parcel data, zoning overlays, utilities or septic capacity, access slope, and site conditions to outline the most straightforward path to approval. (Information provided is general; final eligibility is determined by your parcel details and current local regulations.)
