2 public construction tenders are open in Saint-Eustache, according to SEAO and CanadaBuys as of November 3:
The tenders board · only the official notice counts.
In Saint-Eustache, a permit is required to renovate interior rooms (except for replacing flooring), to replace exterior cladding, or to replace doors and windows when their size changes. Replacing the roof covering, or doors and windows of the same size, does not need one, except in Vieux Saint-Eustache or for a classified or cited heritage building: the project then goes to the planning advisory committee and to council. A minor renovation, such as a kitchen or a bathroom, can be applied for online; other applications are made by appointment with the Planning Department.

In Saint-Eustache, lead, when it is found, most often comes from old pipes, especially service lines (the connection between a home and the municipal network). They were installed mostly between 1940 and 1955, more rarely into the 1970s; the practice has been banned since 1980. Every year since 2014, from July 1 to September 30, the City tests the water of single-family homes and buildings of eight units or fewer, targeting homes built between 1940 and 1955; you sign up with the form on its page, and a home can take part only once every five years. If a lead service line is found, the City replaces the public part; on the private side, it gives recommendations, with no obligation or fine.
