Buena Park, CA Building Setbacks & Zoning: Lot Coverage Limits (2026)

Lot coverage in Buena Park is set by the City's Zoning Code, Title 19, Chapter 19.316 (Building Form), section 19.316.040 (Building Coverage). Subsection A establishes that the maximum building coverage of net lot area for all single-family residential zones shall be 40 percent - this single figure applies across the RS-6, RS-8, RS-10, and RS-16 zones, and is confirmed by the City's Single-Family Residential Development Standards handout ('Total Building Area / Lot Area = 40% Maximum'). Section 19.316.040.B defines what counts toward coverage: all roofed structures over 6 feet in height (measured around the outside bearing walls and support columns), including covered breezeways, recessed entryways, and patio structures whether open-sided, enclosed, trellised, or solid-roofed; plus decks, platforms, porches, or stoops 18 inches or more above the finished grade. Subsection C excludes from coverage: uncovered balconies and eaves, awnings and other cantilevered shading devices, and hardscape such as driveways, parking spaces, walkways, sidewalks, and unenclosed patios and patio covers. A related limit governs rear-yard additions: per the handout and Chapter 19.320, a rear-yard addition may encroach to within 5 feet of the rear property line provided rear-yard coverage (in the rear 25 feet) does not exceed 30 percent. Landscaping is also required: a minimum of 50 percent of each required yard abutting a street must be permanently maintained with landscaping per the City handout (the draft code states 30 percent), and water-efficient landscaping rules apply. The 40-percent lot-coverage cap is a Buena Park zoning standard; it is not set by the California Building Code.
