Lawn Mowing & Grass Maintenance Rules
Grass height limits, ragweed control, and when it's okay to run the mower.
Vaudreuil-Dorion regulates overgrown grass and weeds as part of its general nuisance bylaw, encourages an eco-friendly mowing height through a voluntary program, and restricts the hours noisy yard equipment can run. Some specifics below (exact permitted hours in particular) could not be confirmed from a directly accessible bylaw document and should be verified with the City before you rely on them.
Maximum grass and weed height
Grass and weeds are generally not allowed to grow past 30 cm (about 12 inches) on residential or commercial properties, whether built on or vacant. Vacant lots must still keep a 2-metre maintained strip along the public road. Agricultural land is exempt.

Ragweed (herbe à poux) control
Ragweed is explicitly treated as a nuisance plant under the City's general nuisance bylaw (Règlement no 1781). Property owners are expected to pull or cut it before it flowers, both for allergy-reduction reasons and because it's a bylaw matter.
Écopelouse: an eco-friendly mowing height (recommendation, not a rule)
Through its voluntary Écopelouse program, the City recommends keeping grass at 7.5 cm (3 inches) or higher and leaving clippings on the lawn (grasscycling/herbicyclage) to build healthier, more drought-resistant turf. This is a sustainability recommendation, not a legal minimum height - it doesn't override the nuisance-height maximum above.
Permitted hours for mowers and other yard equipment
Noise-generating yard equipment (lawn mowers, garden tractors, trimmers, chainsaws, leaf blowers) is restricted to certain hours under the nuisance bylaw, and general nuisance noise is prohibited overnight. Search results for the exact permitted windows were inconsistent between sources, and the primary bylaw PDF could not be opened directly during research.
