Mount Vernon's Sign Regulations: The Rules That Matter

Every city handles sign regulations a little differently. In Mount Vernon, New York, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Window Signs

Mount Vernon caps interior window signage at 20 percent of a storefront's aggregate window area, or 10 square feet if that window area is under 100 square feet. Multi-tenant upper-floor buildings get a separate 25 percent cap under City Code Section 267-77.

Key details: Ground-floor cap: 20% of aggregate storefront window area. Small storefront alternative: 10 sq ft if window area under 100 sq ft. Multi-tenant upper-floor cap: 25% of window area. Review body: Commissioner, with Sign Appeals Board input.

A window sign that exceeds the 20 percent ground-floor cap, the 10-square-foot small-storefront alternative, or the 25 percent upper-floor cap under Section 267-77 is classified as a nonconforming sign under Section 267-76.E. Nonconforming signs must be removed, cannot be enlarged or have their message altered, and once removed may only be replaced with a sign meeting the permitted-signs standards.

Political Signs

Mount Vernon caps political and campaign signs at 16 square feet and four feet in height under City Code § 267-77G(9). Candidates or campaign managers must apply to the Commissioner and show owner consent if they don't own the property, and every sign must come down within two weeks after the election.

Key details: Maximum sign size: 16 square feet. Maximum sign height: 4 feet. Roof-mounted political signs: Prohibited. Owner consent: Required if applicant doesn't own property. Public property/right-of-way: Not allowed.

A political sign that exceeds the 16-square-foot/four-foot limit, sits on public property, lacks required owner consent, or remains up past the two-week post-election deadline is immediately subject to a violation from the Building Department under § 267-77G(9)(d), enforced through Chapter 267's general penalty at § 267-56A: up to a $1,000 fine or 15 days imprisonment per conviction, with continuing violations counted daily.

Digital Billboards

Mount Vernon prohibits the construction of any new billboard under City Code § 267-76J, a flat ban that draws no exception for digital or electronic displays. Existing billboards may stay standing if properly maintained, but roof-mounted billboards are excluded from that grandfathering and must come down.

Key details: New billboards: Banned outright, all types. Existing billboards: May remain if properly maintained. Roof-mounted billboards: Not grandfathered, must be removed. Flashing/rotating illumination: Barred for all signs. Enforcing agency: Building Department.

Erecting a new billboard, digital or otherwise, is a zoning violation enforced through Chapter 267's general penalty at § 267-56A: up to a $1,000 fine, up to 15 days imprisonment, or both per conviction, with each day the illegal structure remains treated as a separate violation. The Building Department can also order removal of an unlawfully erected sign.

Compared to other cities, Mount Vernon takes a harder line on digital billboards. The enforcement and penalty structure reflects that.

The Bottom Line

Mount Vernon's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Mount Vernon is broadly strict or permissive.
