Fairfax, VA Animal Ordinances: Pet Limits (2026)

Fairfax County's Chapter 41.1 does not set a strict numerical cap on household pets, distinguishing it from many jurisdictions that impose 3-or-4-dog limits. Instead, the county uses a combination of nuisance, sanitation, and kennel-permit thresholds. Households keeping 4 or more dogs that are more than 4 months old typically must obtain a Commercial Kennel Permit (if operating a kennel business) or may face code enforcement if neighbors complain about noise, odor, or waste. The Fairfax County Zoning Ordinance separately regulates kennels as a land use; kennels are only permitted in agricultural zoning districts or as a Special Exception in other districts. Private rescue organizations and foster homes working with licensed 501(c)(3) rescues have specific exemptions but must register. Cats are not subject to a numerical limit. Puppies under 4 months are not counted toward kennel thresholds. Enforcement is complaint-driven; responsible owners of multiple dogs who maintain clean yards, current licenses, and quiet animals typically encounter no issues. HOAs in planned communities often impose stricter limits (2-3 pets) by covenant.
