Do I need a variance to build an oversized garage in a Fredericton residential neighbourhood?

You may need a variance if your planned garage exceeds the maximum size, height, or lot coverage limits established by Fredericton's zoning by-law for accessory buildings in your residential zone — but whether you actually need one depends entirely on the specific numbers for your property and your zone's rules. The first step is to determine what your zone allows and then compare that to what you want to build.

Fredericton's zoning by-law sets several limits that can trigger the need for a variance on a larger garage. Maximum accessory building footprint is often capped at a specific size — commonly in the range of 80 to 110 square metres (860 to 1,184 square feet) depending on the zone, though larger lots in some zones may permit larger accessory structures. Maximum height for detached accessory buildings is typically limited to one storey or a specific height measurement (commonly around 5 metres or 16 feet at the peak). Maximum lot coverage — the total percentage of your lot covered by all buildings combined — typically ranges from 35% to 45% in Fredericton's residential zones. And setback requirements from property lines must be maintained, which can effectively limit the size of a garage on smaller or irregularly shaped lots even when the coverage percentage would allow a larger footprint.

An "oversized" garage means different things depending on your zone. On a large suburban lot in the newer developments on Fredericton's north side or in the Hanwell Road area, a 24x30 two-car garage (720 square feet) may fit well within all zoning limits. On a smaller lot in an older neighbourhood like Skyline Acres, Devon, or the South Side, the same 24x30 garage might exceed lot coverage or accessory building size limits. The math is straightforward: measure your lot, add up the footprints of all existing structures, check your zone's coverage percentage, and determine the maximum remaining footprint available for a garage.

If your planned garage exceeds one or more zoning limits, you need to apply for a variance through Fredericton's Development Officer or Committee of Adjustment, depending on the type and magnitude of the deviation. A minor variance — typically defined as a deviation of 10% or less from a specific requirement — may be approved by the Development Officer without a full hearing. A major variance requires a hearing before the Committee of Adjustment, which involves submitting an application, public notification to neighbouring property owners, a waiting period for objections, and a hearing where you present your case.

The Variance Application Process in Fredericton

To apply for a variance, you submit a formal application to Fredericton's planning department along with a site plan showing the proposed garage, its dimensions, and its distances from all property lines and existing structures. You must explain why you need the larger garage and why strict compliance with the zoning limit would cause you hardship. The application fee typically ranges from $200 to $500. The committee considers whether the variance is consistent with the intent of the zoning by-law, whether it will adversely affect neighbouring properties (blocking views, creating drainage issues, reducing property values), and whether there are reasonable alternatives that comply with the by-law.

Practical tips for getting a variance approved. Talk to your neighbours before you apply — if adjacent property owners support your request (or at least do not object), your chances improve significantly. A letter of non-objection from the most affected neighbour carries real weight with the committee. Prepare a clear, professional site plan that shows the garage in context with surrounding properties. Explain the legitimate need for the larger size — vehicle collection, home-based trade requiring equipment storage, accessibility needs, or accommodating modern full-size trucks that simply do not fit in a standard single-car garage. Demonstrate that you have minimized the encroachment as much as possible — asking for 15% over the limit is more likely to be approved than asking for 50% over.

Before committing to the variance process, explore alternatives. Could a taller garage with a smaller footprint (using a loft for storage) achieve your goals within the by-law limits? Could removing an existing shed or outbuilding free up enough coverage room? An experienced Fredericton garage contractor can help you design a structure that maximizes usable space while staying within — or as close as possible to — your zoning limits.
