Within Longmont city limits, traditional livestock (cattle, horses, goats, sheep, swine) are not permitted in residential zoning districts. LMC § 7.04.130 (Prohibited Keeping of Animals) bars keeping animals outside their customary residential context; only 4 hens (no roosters) plus inspected pot-bellied pigs are explicitly allowed as residential 'farm' animals.
Longmont Municipal Code does not authorize hoofstock or commercial-style livestock on standard residential lots. Under LMC § 7.04.130 ('Prohibited Keeping of Animals'), animals not customarily kept as residential pets — or that are kept in a manner that creates a public nuisance — are prohibited. The City of Longmont's Animals page enumerates the only farm-style animals expressly permitted on residential property: up to 4 hens (no roosters) with a backyard chicken hen permit under Ordinance O-2011-02, and Vietnamese pot-bellied pigs (licensed individually with a Colorado Certificate of Veterinary Inspection). Roosters are categorically prohibited. Larger livestock — cattle, horses, sheep, goats, ducks, geese, turkeys, swine — are limited to agriculturally-zoned properties under Longmont's Land Development Code (Title 15) and are not allowed as accessory uses in standard residential districts (R-SF, R-MF, etc.). Properties annexed with prior agricultural rights may retain legal-nonconforming livestock. Persons interested in keeping livestock on a Longmont parcel should confirm zoning with Planning & Development Services at (303) 651-8330 before acquiring animals.
Keeping prohibited livestock on residential property: LMC § 7.04.130 + zoning violation under Title 15. Longmont Code Enforcement / Animal Control may order removal. General penalty up to $999 and/or 180 days jail.
