How Sterling Heights Handles Sign Regulations: A Practical Guide
Sterling Heights maintains 120 local ordinances across all categories, and 4 of those deal specifically with sign regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Sterling Heights falls on the strict-to-permissive spectrum compared to other cities.
Political Signs
Sterling Heights regulates campaign and political signs the same as any other temporary sign: up to 9 square feet total on single-family residential lots, set back from property lines, and removed once no longer needed.
Key details: Residential sign cap: 9 sq ft total, all temporary signs. Short-term sign cap: 3 sq ft each. Removal deadline: 7 days after no longer needed. Content rule: Size-based, not message-based.
Oversized or improperly placed temporary signs, including campaign signs, may be removed by the city; owners can be billed removal and storage fees, and signs unclaimed after ten days may be disposed of.
Digital Billboards
Billboards, digital or otherwise, are banned in Sterling Heights outright, with only a narrow carve-out for signs controlled by an outside governmental entity, capped at 25 feet tall and 150 square feet.
Key details: Billboards: Banned citywide (off-premises signs). Narrow exception cap: 25 ft height, 150 sq ft. EMB on business signs: Max 1/3 of sign area. EMB brightness cap: 0.3 footcandles over ambient light.
An unauthorized billboard is a prohibited off-premises sign subject to removal by the city; the sign owner or responsible party can be charged removal, storage, and administrative processing fees under Section 28.13's enforcement provisions.
Compared to other cities, Sterling Heights takes a harder line on digital billboards. The enforcement and penalty structure reflects that.
Holiday Displays
Sterling Heights bans flashing or intermittent exterior lighting citywide under its zoning code, but the same section exempts lighting authorized as holiday decorations under the sign ordinance, so seasonal string lights are allowed.
Key details: Flashing/intermittent lighting: Banned unless authorized under §28.13. Holiday-decoration exception: String lights permitted as holiday decor. Shielding exemption: 100-watt incandescent bulbs exempt. Enforcement: Building Official, Zoning Ordinance Art. 29.
Violations are zoning ordinance infractions enforced by the Building Official under Article 29; noncompliant flashing or intermittent fixtures that don't qualify for the holiday exception can be ordered removed or brought into compliance.
If you are coming from a city with tighter rules, you will find Sterling Heights gives residents more flexibility on holiday displays.
Window Signs
Window signs in Sterling Heights cannot exceed 25% of the glass area of the facade they're displayed on, and no window sign may exceed 150 square feet no matter how much glass the building has. Zoning Ordinance § 28.13(O) sets the cap, and the same section's general sign rules on maintenance, obsolete removal and enforcement apply to window signs like every other sign type in the city.
Key details: Size limit: 25% of facade glass area. Absolute cap: 150 square feet. Obsolete-sign removal: within 30 days. Violation cure window: 48 hours after written notice. Unclaimed removed sign: disposed of after 10 days.
A window sign over the 25%-of-glass or 150-square-foot cap is a code violation subject to the same enforcement track as any other sign: written notice of the violation, then 48 hours to cure it before the city can remove the sign. The city can charge a fee to release an impounded sign, and an unclaimed sign is disposed of after ten days. Filing a false affidavit or sign application is a misdemeanor under City Code § 1-9, and owners, lessors, and lessees can all be held responsible for the violation under § 28.13(I)(9).
The Bottom Line
Sterling Heights'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 Sterling Heights is broadly strict or permissive.
