Fairfax FAQ
Can I legally keep 5 dogs in Fairfax County?
Yes, as long as they don't create a nuisance, are licensed, and you're not operating a kennel business. A neighbor complaint could trigger scrutiny.
What triggers a kennel permit requirement?
Commercial activity (breeding, boarding for pay, training for pay) with 4+ dogs. Pure household ownership without commercial activity generally doesn't require a kennel permit.
Are foster homes regulated differently?
Yes. Foster homes affiliated with a registered 501(c)(3) rescue have specific exemptions from kennel rules when fostering for adoption.
Vienna FAQ
Can I keep 5 dogs in my Vienna home?
Only with a kennel permit from Fairfax County, which requires facility inspection and may trigger Special Exception zoning review.
Do puppies count toward the limit?
No. Animals under 4 months are not counted, but they begin counting on the day they reach 4 months of age.
