Summary
Buena Park lets patios, decks, and other non-habitable accessory structures in single-family zones get ministerial approval up to 600 square feet or half the home's floor area; anything larger needs a discretionary conditional use permit under § 19.316.080.
Examples of non-habitable accessory structures may include garages, patios, carports, storage sheds, gazebos, cabanas, pool houses, workshops, and other similar structures.
B. Notwithstanding other provisions of this Division, the floor area of all non-habitable accessory structures shall not exceed 50 percent of the habitable residential floor area of the primary dwelling or 600 square feet, whichever is less. Non-habitable accessory structures shall be approved ministerially if the site plans are in compliance with all applicable development and design standards. Non-habitable accessory structures greater than 50 percent of the habitable residential floor area or 600 square feet shall require a conditional use permit pursuant to Section 19.128.020.
C. A canopy, including support structure, may be installed within the side or rear yard setbacks in single-family residential zones if it complies with the following standards:
1. The canopy may be located within a side yard abutting a street provided it is located behind a solid block wall or fence maintaining a minimum height of five (5) feet.
2. The canopy shall be firmly attached to the ground or the primary structure.
3. The canopy shall be maintained in good condition and structurally sound, and shall be removed, cleaned, or replaced if faded, torn, tattered, dirty, or missing.

Full Breakdown
Buena Park Municipal Code § 19.316.080 treats patios, decks, gazebos, cabanas, carports, and storage sheds in the city's single-family residential zones as non-habitable accessory structures capped at 50 percent of the primary home's habitable floor area or 600 square feet, whichever is smaller. A structure within that cap is approved ministerially once staff confirms the site plan meets applicable development and design standards: no public hearing required. Exceed the cap and the homeowner must instead obtain a conditional use permit under § 19.128.020, triggering discretionary Planning Commission-level review before construction can begin.
Violations & Fines
Building a patio, deck, or other accessory structure over the 600-square-foot/50-percent cap without the required conditional use permit is a zoning code violation: a misdemeanor punishable by up to $1,000 and six months in jail under § 19.148.010.
