Summary

Howard County lets a single-family home run up to two home occupation signs, but each one is capped at two square feet, has to sit back at least six feet from the property line, and can't rise more than five feet off the ground. The rule sits in the county's sign code, separate from the zoning standards that govern the home business itself.

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.

(b)Residential Districts and Residential Areas.(1)Single-family. Two home occupation signs not exceeding two square feet each in area shall be permitted per single-family dwelling. Such signs shall be set back at least six feet from the nearest property line and shall not be over five feet above the ground, whether freestanding or on a building. Other signs for single-family dwellings shall be subject to the standards set forth in subsection 3.503(g). Illumination shall be in accordance with the restrictions set forth in section 3.508.

Full Breakdown

501(b)(1) of the Howard County Code, part of Subtitle 5, 'Signs,' sets the standard specifically for single-family home occupation signage: two home occupation signs not exceeding two square feet each in area are permitted per single-family dwelling, set back at least six feet from the nearest property line, and no more than five feet above the ground, whether freestanding or on a building. 503(g). 508, so a lit or internally-illuminated sign has its own compliance check beyond the size and setback numbers. 501 apply county-wide to every existing and future zoning district, including the multiuse and planned community districts common in unincorporated communities like Columbia and Ellicott City, with only Downtown Columbia carved out for different commercial sign treatment under the Downtown Columbia Plan. 509 of the same subtitle, alongside the fee schedule the County Council adopts for sign permits generally.

Violations & Fines

A home occupation sign that exceeds two square feet, that a homeowner puts up as a third sign, or that sits closer than six feet to the property line or higher than five feet does not meet Section 3.501(b)(1) and is treated as a nonconforming or prohibited sign subject to removal, the same enforcement path used for other sign violations under this subtitle.

Frequently Asked Questions

How big can my home business sign be in Howard County?
Up to two square feet per sign, and you're limited to two such home occupation signs per single-family dwelling under Section 3.501(b)(1). Each sign also has to sit back at least six feet from your property line and can't be more than five feet above the ground.
Can I light up my home occupation sign?
You can, but illumination has to comply with the separate restrictions in Section 3.508 of the sign code, in addition to meeting the size, setback, and height limits set for home occupation signs under Section 3.501(b)(1).
Does this sign rule apply the same way in Columbia and Ellicott City?
Yes. Since neither is an incorporated municipality, the county's sign standards in Section 3.501 apply the same way there as everywhere else in Howard County, with the one carve-out being Downtown Columbia's separate commercial sign rules under the Downtown Columbia Plan; that carve-out doesn't change the home occupation sign limit.
