A conviction under Section 26.1 is a misdemeanor punishable by a fine of up to $1,000, with each day the illegal sign remains standing a separate offense; the county may instead pursue a civil citation under Section 26.2.1, capped at $500 per violation and doubling if unpaid within 15 days.

Frequently Asked Questions

Can a new billboard go up along I-81 or US 40 in Washington County, Maryland?
No. Section 22.24(c)(2) bans new outdoor advertising signs within 1,000 feet of the centerline of named corridors including U.S. Route 40/MD 144, MD 68, MD 65, MD 34, MD 63, U.S. 340, MD 60 and MD 67, covering most of the county's interstate and U.S.-route frontage.
How big can a legal billboard be under county zoning?
Section 22.24(c)(4)-(6) caps each face at 300 square feet, cumulative area on one structure at 600 square feet, height at 30 feet from the lowest road grade, and limits the sign to two faces mounted back to back.
Does an existing billboard have to come down if it's nonconforming?
Not automatically, but Section 22.24(b) freezes it: no increase in size or height is allowed, and Section 22.24(c)(3) makes the highway corridors listed in the ordinance priority areas for removing existing nonconforming signs.
