South San Francisco FAQ
Is it illegal to feed deer or coyotes in unincorporated San Mateo County?
The County Ordinance Code does not contain a specific wildlife-feeding ban that we could confirm. County agencies strongly advise against feeding wildlife because it attracts predators like coyotes and mountain lions and can make animals aggressive. Feeding that creates a nuisance, or feeding protected wildlife under state law, can still trigger enforcement.
Why does the County discourage feeding wildlife?
