Longmont permits home occupations as an accessory use in residential zones under the Land Development Code (Title 15), provided the activity stays clearly subordinate to the dwelling, is conducted by at least one resident, has no more than one non-resident employee, and does not adversely affect surrounding properties. A Home Occupation Affidavit is required.
Home occupations are regulated as an accessory use under Longmont's Land Development Code (LMC Title 15), which governs accessory uses and structures in residential districts including Rural Residential (R-RU), Residential-Single Family (R-SF), Residential-Mixed Neighborhood (R-MN), and Residential-Multifamily (R-MF). The activity must be conducted entirely within the principal dwelling or an accessory structure associated with the residential use and must be carried on by at least one resident of the principal dwelling, with no more than one additional non-resident employee on-site. No substantial retailing or wholesaling of stocks, supplies, or products may be conducted on the premises, though delivery of retail products off the premises (such as mail-order business) is permitted. Exterior storage of supplies or materials used in the home occupation is prohibited. Before operating, a resident must submit a completed Home Occupation Affidavit to Longmont Planning & Development Services. Businesses also need a Sales and Use Tax License from the City Finance Department ($25 one-time fee).
General penalty under LMC § 1.16.020: up to $2,650 fine and/or up to 364 days imprisonment per violation, plus possible revocation of the home occupation affidavit and zoning enforcement action.
