Construction permits for Backyard Offices and Garden Studios are often viewed as a bit of a confusing world. The good news is that in most Canadian jurisdictions a planning permit is not required for a structure with a footprint of less than 10 m2 (107 sq. ft.) which is how we design our structures.
Common Jurisdiction/City rules for Backyard Offices and Garden Studios Permits
Most cities in Canada have a clear statement on their website stating the rules for building less than 10 m2.
Using the City of Calgary as an example the City web site says the following says the following:
- Buildings under 10 m2 (107 sq. ft.)
The most important rule under location is that the “accessory building” is not within 0.6m of the property line. Being less than 0.6m complicates construction methodology requiring the following:
- When building within 0.6m (1.9 ft.)of the side property line the exterior of the accessory residential building needs to be fire rated with 5/8” type x drywall from floor slab to underside of roof sheathing to interior face of wall assemblies.
Design rules cover the percentage of the property that is allowed to be constructed on. This will depend on the Land Use District R-1, R-2, etc. and the size of the property. Happily, “If the aggregate area of all accessory buildings is under 10 m2 (107 sq. ft.) those structures will not contribute to parcel coverage.” So if this is your only outside structure apart from a garage everything is good. If you already have a shed we may need to look a little closer for properties with smaller backyards.
