Each jurisdiction has a certain set of rules covering building setbacks. In the city of Calgary, the garage may go directly on the property line if certain conditions are met: 1. The property is not shared with the street 2. The wall is fire rated with 5/8" type x drywall from floor slab to underside of roof sheathing 3. There is no eave overhang onto the adjacent lot (reverse Gable Construction Reccomended) 4. There are no windows or doors on the property line side of the garage 5. There are no neighbouring sheds, garages within 2 ft' of the property line (For building purposes) 6. In case the garage will need to be placed on the Maintenance Right of Way or a Utility Right of Way, make sure to check with the relevant caveats and encumbrances registered on the title document to ensure it's allowed Ethics: Despite meeting all of the above building code restrictions and legally obtaining the permits, it is a good practice to be a "Good Neighbour" and keep a healthy relationship with your next-door neighbours. Especially when building on or close to the property line, we strongly recommend discussing your building plans with both of your neighbours and notifying them of your intentions. In addition, we strongly recommend having your property staked out by a professional surveyor (may be provided by Alta Home for a fee) prior to commencing your build on or near property lines. This will ensure your structure remains within your property and doesn't encroach on adjacent or city lots avoiding costly issues.
