Frequently asked questions
Boulder's zoning laws specify types of business uses allowed at specific locations. Each property is in a designated zoning district and each zoning district lists the allowed uses for that district. Some types of business uses or those with certain operating characteristics are only allowed with a public review process such as "use review." Email a Project Specialist in the Planning & Development Services Center or call 303-441-1880 to learn more about zoning districts and to confirm that your proposed business use is allowed before signing a lease or purchasing a property.
Home occupations are allowed in Boulder for businesses that meet the following standards:
- A home occupation is a permitted accessory use if the following conditions are met:
- Such use is conducted entirely within a principal or accessory building and is not carried on by any person other than the inhabitants living there.
- Such use is clearly incidental and secondary to the residential use of the dwelling and does not change the residential character thereof.
- The total area used for such purposes does not exceed one-half the first floor area of the user's dwelling unit.
- There is no change in the outside appearance of the dwelling unit or lot indicating the conduct of such home occupation, including, without limitation, advertising signs or displays.
- There is no on-site sale of materials or supplies except incidental retail sales.
- There is no exterior storage of material or equipment used as a part of the home occupation.
- No equipment or process is used in such home occupation that creates any glare, fumes, odors or other objectionable condition detectable to the normal senses at the boundary of the lot if the occupation is conducted in a detached dwelling unit, or outside the dwelling unit if conducted in an attached dwelling unit.
- No traffic is generated by such home occupation in a volume that would create a need for parking greater than that which can be accommodated on the site or which is inconsistent with the normal parking usage of the district.
