When a project cannot meet a sign-code limit — too tall, too large, too close to the line — the formal remedy is a variance: permission from the zoning board (often called the Board of Zoning Appeals or Board of Adjustment) to deviate from the rule. A variance is a real legal tool, but it is slow, public, and decided on evidence of hardship, not on what the client wants. Manage expectations before you promise one.
What a variance actually requires
Most jurisdictions require the applicant to prove some version of these elements:
- Hardship unique to the property. A physical condition of the parcel — an odd shape, severe slope, an obstruction, a deep setback line — that makes compliance impractical. General business inconvenience does not count.
- Not self-created. The hardship cannot be something the owner caused.
- No harm to neighbors or public. The variance must not damage surrounding property values, sight lines, or public safety.
- Minimum necessary. Boards grant the smallest deviation that solves the problem, not the largest the applicant requests.
The process and timeline
A variance is not an over-the-counter approval. It typically means an application fee, a site plan and justification narrative, mailed notice to surrounding property owners, a posted public hearing, and a board vote — often weeks to a few months out. Plan the schedule around it, and budget for the possibility of denial.
When to pursue one vs. redesign
Often the cheaper, faster path is to redesign within the code. If a sign is over the area limit, shrinking it beats a hearing. A variance makes sense when a real physical hardship — for example, a deep mandated setback that pushes a sign so far back it cannot be seen — genuinely prevents a reasonable sign. Bring evidence, not just a preference.
Real-municipality example
In Ann Arbor, Michigan, requests to exceed sign limits go before the Zoning Board of Appeals, which weighs whether a practical difficulty or hardship specific to the property justifies the deviation, after public notice and a hearing. A national retailer asking for a sign larger than the ordinance allows simply because that is its brand standard will struggle there — the board is looking for a property-based hardship, not a corporate template. Check whether your municipality’s board uses a “practical difficulty” or stricter “hardship” standard before advising a client to apply.
Overlays raise the bar
Inside a historic district overlay, a variance may also require sign-off from a preservation or design-review board in addition to the zoning board — two approvals, two standards. Account for both when estimating timeline and odds.
Practical takeaway for installers
Treat a variance as a last resort with real cost and real uncertainty. Confirm the board’s standard, the hardship evidence available, the notice and hearing timeline, and whether an overlay adds a second approval. Often a code-compliant redesign is the smarter bid.
