When You Need a Variance and How to Apply for One

A variance is permission to depart from a dimensional standard — a setback, a height limit, a lot coverage figure — because something about your specific parcel makes the standard unusually burdensome. It is not a licence to build whatever you like, and it is not the right tool for a project the zoning does not permit at all. Understanding which of those situations you are in saves months.

Variance, appeal and redesign are three different things

These paths get confused constantly, and picking the wrong one wastes the most time. A variance asks the board to excuse you from a dimensional standard because the parcel itself creates the difficulty. An administrative appeal argues that the department got the decision wrong — that your project already complies, or that the official applied the wrong section. A redesign changes the project so that no relief is needed.

The order in which you try them matters. A redesign is almost always the fastest and cheapest option, because it avoids a hearing entirely. Departments will often tell you what would be approvable if you ask, and a modest change in footprint or location resolves a surprising share of cases. Treat a variance as the path you take when the parcel genuinely cannot accommodate a compliant design.

What counts as a hardship

Hardship is the heart of a variance, and it is narrower than most people expect. The difficulty has to arise from the land, not from the owner’s preferences or from a problem the owner created. A steep slope, an unusual lot shape, a drainage course or a shallow bedrock layer can all support a finding of hardship. Wanting a bigger garage, or having already built something in the wrong place, generally cannot.

This is why self-created hardship is the most common reason applications fail. If you built a shed too close to the line and now want to enclose it, the hardship was created by the choice, not by the parcel, and most boards will deny the request. The same project proposed before construction began, with the slope or the lot geometry as the stated reason, has a very different prospect.

Financial hardship alone is rarely enough. Showing that a compliant design costs more is not the same as showing that compliance is unreasonably burdensome given the physical characteristics of the lot.

The findings the board usually has to make

Boards do not grant variances because a request seems reasonable. They have to make specific findings on the record, and a good application is organised around those findings rather than around the applicant’s preferences. While the wording varies, most jurisdictions ask some version of the following.

  • The hardship is unique to this parcel and not shared by the neighbourhood generally.
  • The hardship arises from the physical characteristics of the land, not from the owner’s actions.
  • Granting the variance will not change the character of the neighbourhood.
  • The relief requested is the minimum necessary, not the maximum the applicant would like.
  • The variance will not harm neighbouring properties, public health, safety or welfare.
  • The difficulty is not one the applicant could reasonably have avoided.

Notice that most of these findings are about impact rather than intent. An application that shows the project will not be visible, will not shed water onto a neighbour, and will not affect sight lines is answering the questions the board is actually required to ask.

How the process runs

Deadlines come first. Appeal and variance windows are often short, and missing one can leave a redesign as the only remaining option. Once you file, the department will usually require notice to neighbouring owners within a set radius, published notice, or both, and the hearing date follows that notice period.

At the hearing, the board is looking for a clear, specific ask. The most effective presentations are short: a site plan showing the compliant option and why it fails, photographs of the physical condition creating the difficulty, and one number you are asking to change. Bring the dimension, not a narrative.

If the variance is granted, it usually runs with the land and often carries conditions, such as a specific footprint, screening, or drainage provisions. Check whether the approval expires if you do not pull a permit and start work within a set period, because that catches people regularly.

If the variance is denied

A denial is not the end of the project. Ask the board or the staff what revised design would be approvable, and ask it in the room, while the plan is in front of them. That answer is the most valuable thing you will get from the process.

Also check whether the standard you are asking to vary has been changed by state law. For accessory dwelling units in particular, several states now prohibit discretionary hearings for units that meet objective standards, which can remove the need for a variance altogether. Where that applies, the correct response to a denial may be to cite the statute rather than to redesign.

Take this to your department

  1. Get the denial or the applicable standard in writing, with the code section cited.
  2. Ask what design would be approvable without a hearing before filing anything.
  3. Confirm the filing deadline for an appeal or a variance application.
  4. Write the hardship around the physical condition of the lot, not around cost or preference.
  5. Prepare one site plan showing the compliant option and the specific dimension you need.
  6. Ask whether a statewide statute, such as an ADU law, removes the standard you are varying.
  7. If granted, confirm the conditions, any screening or drainage requirements, and the expiry date.

Frequently asked questions

What is the difference between a variance and an appeal?

A variance asks for relief from a dimensional standard such as a setback or height limit, because the parcel makes compliance unusually hard. An appeal argues the decision itself was wrong — that your project already complies or that the official applied the wrong section. They have different deadlines and different decision makers, so confirm which one fits before you file.

Is wanting a larger building a valid hardship?

Usually not. Hardship generally has to come from the physical characteristics of the land, such as slope, lot shape or a drainage course, and not from the owner’s preferences or from a difficulty the owner created. Wanting more space, or having already built in the wrong place, is typically treated as self-created.

How long does a variance take?

It depends on the hearing calendar and the notice period, which is why a redesign that needs no hearing is usually faster. Ask the department for the next available hearing date and the filing deadline at your first conversation, and plan contractor and material schedules around the later of the two.

Does a variance transfer if I sell the property?

Variances usually run with the land rather than with the owner, so they generally survive a sale. However, they often carry conditions and may expire if a permit is not pulled or work does not begin within a set period. Keep the written approval with your property documents.
