Fairfield FAQ
Can I build a shed in my Fairfield side yard?
Accessory structures under 120 square feet and 12 feet tall generally don't require a building permit but must still comply with zoning setbacks—typically at least 3 feet from side and rear property lines for small detached structures. Larger sheds require permits and full setback compliance per Section 25.20.
Are ADU setbacks really only 4 feet in Fairfield?
Yes. California Government Code 65852.2 preempts local standards for new detached ADUs, mandating no more than 4-foot side and rear setbacks. Fairfield's zoning ordinance and ADU standards conform. Front setbacks for ADUs typically still follow the underlying zone.
Vallejo FAQ
How do I find my setback requirements?
Check Vallejo zoning map for your parcel’s zoning district, then consult the zoning code for that district’s setbacks.
Can I build closer than the setback?
Only with a variance approved by the zoning board or if your structure qualifies for an exception.
