This guide explains typical limits on customer visits, who enforces the rules in Thornton, how to apply for a home occupation permit, and practical steps to stay compliant.

What is a Home Occupation Permit and customer visit limits

A home occupation permit authorizes low-impact business activities in a residence while protecting neighborhood character. Customer visit limits set how many non-resident clients or customers may come to the home during a day or week, and may distinguish between scheduled appointments and deliveries. Thornton regulates home occupations through its land use/zoning rules and related permit process.

Check zoning before you advertise in-person services from home.
