Thousand Oaks limits the percentage of each lot that can be covered by structures and impervious surfaces under TOMC Chapter 9. Typical lot coverage in residential zones ranges from 25% to 40% depending on lot size and zoning district. ADUs may have exceptions under state law.
TOMC Chapter 9 establishes maximum lot coverage by zoning district. In single-family residential zones, lot coverage (defined as the total area of all roofed structures divided by the total lot area) typically ranges from 25% for larger lots to 40% for smaller lots. Impervious surface coverage (including driveways, patios, and walkways) may have separate or combined limits. Covered patios, carports, and accessory structures all count toward lot coverage. Uncovered decks, pergolas without solid roofs, and swimming pools may or may not count depending on the specific zone regulations. ADUs benefit from state law provisions that may allow additional lot coverage above the base zoning limit, up to 800 square feet regardless of lot coverage maximums. The city calculates lot coverage as part of every building permit application review.
Exceeding lot coverage limits without approval is a zoning violation. Building permits will not be issued for projects exceeding coverage limits. Existing violations may require removal of structures to achieve compliance.
