Antioch FAQ
Can I do DIY home projects on Sunday?
Quiet interior work like painting or hand-tool carpentry is generally allowed. Power tools, hammering, and outdoor construction noise audible to neighbors on Sundays may violate Antioch's noise ordinance.
How do I get approval for after-hours construction?
Contact Antioch Community Development to request a special construction permit. Typical reasons for approval include concrete pours that must be continuous, traffic-sensitive roadwork, or emergency repairs.
