A zoning variance is permission to depart from a specific zoning rule, such as a setback, height limit or lot coverage cap, on one particular property. It is the formal route when a project can’t be redesigned to fit the code. Variances are granted case by case, usually after a public hearing, and they are harder to win than most people expect, so it pays to understand the standard before you apply.
Quick answer: A zoning variance is an exception to a zoning requirement granted by a board (often a board of zoning appeals or adjustment) for a specific lot. You typically must show a hardship caused by the property itself, such as an unusual shape or slope, not by personal preference. The process involves an application, drawings, neighbour notice and a public hearing.
What a zoning variance can and can’t do
Most variances are “area” or “dimensional” variances: relief from setbacks, height, lot size, frontage or coverage. Many places do not allow “use” variances for homes, or make them much harder; changing what a property can be used for usually needs a rezoning or a conditional use permit instead. Our pillar guide on setback requirements explains the rules a variance would relax.
The hardship standard
Boards generally look for some version of these tests, though wording varies by state and city:
- A unique property condition. Something about the land itself, such as an irregular shape, narrow width, steep slope, or an easement, makes strict compliance difficult.
- Hardship not self-created. The difficulty was not caused by the owner, for example by building without a permit or selling off part of the lot.
- Minimum relief. The variance requested is the smallest that solves the problem.
- No harm to neighbours or the area. Granting it won’t harm adjoining properties or change the character of the neighbourhood.
Wanting a bigger room, saving money or matching a neighbour’s non-conforming house are rarely enough on their own.
Variance vs administrative adjustment
Before applying for a variance, check whether your code offers an administrative adjustment (sometimes called a minor variance or administrative modification). Many cities let planning staff approve small deviations, often a limited percentage of a setback, without a hearing. It is faster and cheaper. A full variance is for larger deviations or where no adjustment process exists.
How the variance process works
- Pre-application meeting. Talk to planning staff. They will tell you whether a variance is the right tool and what the board will want to see.
- Application. Submit the form, fee, a written justification addressing each hardship test, and drawings.
- Notice. The city notifies neighbours within a set distance, and often posts a sign on the property.
- Staff report. Planning staff review the request and may recommend approval, approval with conditions or denial.
- Public hearing. You present your case; neighbours can speak for or against; the board decides.
- Decision and conditions. If approved, follow any conditions. Then apply for the building permit, citing the variance.
Drawings for a zoning variance application
The board needs to see exactly what you are asking for. Typical submittals:
- A site plan showing the existing conditions, the proposed work and the required and proposed setbacks side by side.
- A clear dimension of the deviation (for example, “proposed 6 ft, required 10 ft, variance 4 ft”).
- Elevations if height or appearance is relevant.
- Photos of the property and street.
- The features that create the hardship, such as the slope, easement or irregular boundary, drawn and labelled.
Accuracy matters: reviewers and neighbours will measure your drawings. See how setbacks are measured to get the dimensions right, and our site plan service if you need a variance exhibit drawn.
Improving your chances
- Explore alternatives first and show the board you did. Boards respond well to applicants who tried to comply.
- Talk to neighbours before the hearing. Letters of support help; surprised opponents hurt.
- Ask for the minimum. A smaller request is easier to grant.
- Address each test in writing, using the code’s own words.
- Bring clear exhibits. A simple diagram of the hardship often explains more than a long argument.
After the variance is granted
An approved variance is not a building permit. You still apply for the permit, and the plan reviewer will check that your drawings match exactly what the board approved, including any conditions such as screening, height limits or a maximum footprint. Keep a copy of the decision with your permit documents, and build precisely to the approved dimensions, as inspectors may measure.
Variances vs other approvals
A variance is often confused with other zoning tools:
| Approval | Used for |
|---|---|
| Variance | Relief from a dimensional rule (setback, height, coverage) on one lot |
| Administrative adjustment | Small deviations approved by staff without a hearing |
| Conditional or special use permit | A use allowed only with approval and conditions |
| Rezoning | Changing the zoning district itself |
Asking for the wrong one wastes time and fees, so confirm the right tool with planning staff first.
Common variance situations
Typical successful cases include a narrow or wedge-shaped lot where standard side setbacks leave an unbuildable strip, a steep slope that forces a garage toward the street, or a corner lot whose two front setbacks leave little room; see corner lot setbacks. Typical refusals involve large additions purely for extra space on ordinary rectangular lots.
Frequently asked questions
How long does a zoning variance take?
It depends on the board’s meeting schedule and notice requirements. It commonly takes several weeks to a few months from application to decision.
Can neighbours stop a variance?
Neighbours can object at the hearing, and boards weigh their concerns, but the decision rests on the legal standards, not a vote of the neighbours.
Does a variance stay with the property?
Usually yes, a granted variance runs with the land, though many expire if construction does not start within a set period.
What if my variance is denied?
You can redesign, reapply with a different request after any waiting period, or appeal according to your state’s procedures.
Do I need a lawyer for a variance?
Not usually for a simple residential setback variance. Clear drawings, a written answer to each hardship test and neighbour support are often enough. For contested or complex cases, a land use attorney can help.
