City-level ADU regulations for Buena Park, California. This skill should be used when answering ADU questions specific to Buena Park — local ordinance provisions, development standards, permit process, fees, fire (OCFA) requirements, zoning, and anything that differs from or adds to California state ADU law. This skill layers on top of the california-adu state law skill. Load state law first, then use this skill for Buena Park-specific requirements.
This skill contains Buena Park's city-level ADU rules — the local ordinance, development standards, permit process, fees, and fire/zoning requirements that supplement or override California state ADU law.
How this skill relates to state law: The california-adu skill covers the state floor (Gov. Code §§ 66310-66342). This skill covers what Buena Park adds, matches, or potentially conflicts with. Always load state law context first, then layer this skill on top for city-specific questions.
What this covers: Buena Park Municipal Code § 19.348.010, Title 15 building codes, Title 19 zoning, OCFA fire requirements, permit process, fees, and local development standards.
What this does NOT cover: State-level ADU law (use california-adu skill), federal requirements, or project-specific engineering.
