Summary

Dorchester County lets residents run a business out of their home only as a Home Occupation under Zoning and Land Development Standards Section 10.4.3(A). The business must stay entirely inside the house or an accessory structure, use no more than 25% of heated and cooled floor space or 500 square feet of accessory space, employ only residents of the home, and carry a County Business License.

These county ordinances apply to unincorporated areas of Dorchester County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

1) Home occupations shall be conducted entirely within the principal residence or within a permitted accessory structure on the premises. 2) Only occupants of the principal residence are permitted to be engaged in such occupation or employed to assist in the operation of this home occupation. 3) The home occupation shall not exceed twenty-five percent (25%) of the total heated and cooled floor space of the dwelling or no more than 500 square feet of permitted accessory structures. ... 7) A County Business License is required for a home occupation.

Full Breakdown

3(A) of the county's Zoning and Land Development Standards (Ordinance 04-13) sets eight conditions a home-based business must meet before the county will treat it as a lawful accessory use. The operation must be conducted entirely within the principal residence or within a permitted accessory structure on the same lot; no offsite work locations count. 3(A)(2). 3(A)(3). 5. 3(A)(8). 3(A)(7) requires every home occupation to hold a County Business License, issued after Planning and Zoning staff confirm the use fits within these standards. 2(c) also bars using an accessory structure for a business except a licensed Cottage Industry, most home occupations are expected to stay inside the residence itself or a small, code-compliant accessory building rather than a large detached shop.

Violations & Fines

A home occupation that grows past the 25%/500-square-foot cap, hires non-resident help, or shows outward signs of commercial activity is out of compliance with 10.4.3(A) and can have its County Business License denied or revoked by Planning and Zoning staff. Continued operation without a valid license or zoning compliance exposes the property owner to county code enforcement action and citation as an illegal use under the zoning ordinance.

Frequently Asked Questions

How much of my house can my home business use in Dorchester County?
Under Zoning and Land Development Standards Section 10.4.3(A)(3), a home occupation is capped at 25% of the home's total heated and cooled floor space, or no more than 500 square feet if it's run out of a permitted accessory structure instead of the house itself.
Do I need a license to run a business from my home in unincorporated Dorchester County?
Yes. Section 10.4.3(A)(7) requires a County Business License for every home occupation, and 10.4.3(A)(8) requires you to disclose on a Restricted Covenants Statement whether a recorded covenant on the property would bar the business before the county will authorize it.
Can I hire an employee for my Dorchester County home business?
No. Section 10.4.3(A)(2) of the Zoning and Land Development Standards limits staffing to people who actually live at the residence, so bringing in an outside employee or assistant disqualifies the operation from being treated as a lawful home occupation.
Can I put up a sign advertising my home business?
Only signage permitted under Section 13.5 of the zoning ordinance is allowed; 10.4.3(A)(4) otherwise bars any exterior alteration or visible evidence that a business is being operated from the residence.
