Summary

Howard County's Zoning Regulations let residents run small home-based businesses as accessory uses. Home-based contractors are allowed in the RR and RC rural districts and on residential lots larger than one acre in the R-ED, R-20, R-12, and R-SC districts, subject to specific limits on vehicles, storage, and employees.

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

The Howard County Zoning Regulations have provisions to allow County residents to operate small contracting businesses from their homes in the RR (Rural Residential) and RC (Rural Conservation) districts and from residences on lots greater than one acre in the R-ED, R-20, R-12, and R-SC zoning districts, subject to certain limitations.

Full Breakdown

Because Howard County is charter home-rule and almost entirely unincorporated, the county Zoning Regulations govern home businesses everywhere, including Columbia and Ellicott City. Home occupations must stay clearly incidental to the residential use. The home-based contractor provisions require at least 60 feet of public-road frontage, cap outdoor storage at 2% of lot area (1,000-5,000 sq ft depending on district), limit added commercial vehicles, and bar vehicle/equipment activity between 7:00 p.m. and 6:30 a.m. Storage must meet accessory-structure setbacks, with heavy equipment kept 50 feet from property lines.

Violations & Fines

Operating a nonconforming home business is a zoning violation enforced by Planning and Zoning, with notices, fines, and orders to cease until a permit is obtained.
