LOCAL CONSIDERATIONS · Dollard-des-Ormeaux
What is different about repairs here
- Outdoor equipment is prohibited in the front yard and allowed in the secondary front, side and rear yards, so a technician reaches the unit from the side or back.
- The nuisance by-law sets heat pump noise limits of 55 dBA from 7 a.m. to 10 p.m. and 50 dBA overnight, so a noisy unit is worth checking.
- The city's zoning by-law was replaced in May 2025 (R-2025-199), so reference sheets that quote the former by-law 82-704 are out of date.
