Antioch FAQ
What if I adopt a fourth dog?
You would need to apply for a kennel permit through Antioch Community Development, which most residential zones do not allow. Alternatively, rehome one of your existing dogs or verify if a temporary foster exemption applies.
Do service animals count toward the pet limit?
No. Service animals and emotional support animals with proper documentation are not counted against the household pet limit under the federal Fair Housing Act and ADA protections.
Brentwood FAQ
How many dogs can I own in Brentwood?
Generally 3-4 adult dogs (over 4 months) per household without a kennel permit. Additional dogs require application to Brentwood Planning for kennel authorization, which includes zoning review and neighbor notification.
Do foster dogs count toward the limit?
Often yes, unless you're affiliated with a licensed 501(c)(3) rescue that has a kennel or foster-network permit. Confirm your status with Contra Costa Animal Services before fostering multiple animals.
