Summary

Wilmington allows home businesses by right if low-intensity, but caps customers, signage, and staff: anything busier needs a zoning board special exception under City Code § 48-131.

Low-intensity home occupation, limited to one per dwelling unit and provided that it is conducted without: a. The sale or storage of any stock-in-trade on the premises; b. The presence of more than two customers or clients on the premises per hour; c. Any external evidence or effect of such occupation, except that either a nonilluminated interior window sign not exceeding 144 square inches in area...shall be permitted;...g. The assistance of off-site employees, agents, or associates; and h. The interior storage of hazardous materials.

Full Breakdown

In residential districts, a "low-intensity home occupation" run by the resident alone is permitted by right under Sec. 48-131(c)(8), but only one per dwelling unit, no stock-in-trade sold or stored on-site, no more than two customers or clients per hour, no exterior signage beyond a 144-square-inch interior window sign or facade plaque, no off-site employees, and no hazardous materials stored indoors. A "moderate-intensity home occupation", one that brings in a single outside worker, is not permitted by right; it requires Zoning Board of Adjustment approval as a special exception under Sec. 48-131(d)(4), with similar customer and signage caps.

Violations & Fines

Running a home business past these limits (extra staff, walk-in traffic, exterior signage, stored inventory) without Zoning Board approval is a zoning violation enforceable by the Department of Licenses and Inspections, up to denial or revocation of the certificate of occupancy.

Frequently Asked Questions

Do I need a permit for a small home-based business in Wilmington?
Not if it qualifies as a low-intensity home occupation: resident-run, no outside employees, no stock-in-trade on site, and under two customers per hour meets the by-right standard in § 48-131(c)(8).
What if I want to hire an assistant who doesn't live with me?
That makes it a moderate-intensity home occupation, which requires Zoning Board of Adjustment approval as a special exception under § 48-131(d)(4), not automatic permission.
