Home-Based Business Rules
Connecticut municipalities regulate home-based businesses through local zoning ordinances, which vary widely. Most towns allow home occupations as an accessory use in residential zones with restrictions on exterior signage, employee visits, and the proportion of the home used for business. Connecticut's dense suburban character means home business regulations are strictly enforced in many communities.
