Fallbrook FAQ
What are the building setbacks for my property?
Setbacks depend on your zoning designation. Contact County PDS or check the Zoning Ordinance for your specific zone. Setbacks vary significantly between rural, semi-rural, and village residential zones.
Can I get a reduced setback?
You may apply for a variance, which requires demonstrating a hardship related to your property. Variances are not routinely granted and require a hearing before the Board of Supervisors or Zoning Administrator.
