Property assessment roll

The property assessment function is under the jurisdiction of the Longueuil agglomeration. For the territory of Saint-Lambert and the other related municipalities, it is overseen by the agglomeration’s Assessment Department.

Visit the Property Assessment page of the Ville de Longueuil website to consult the assessment roll, register a change of address, or apply for a review of your property assessment. You can also call the agglomeration’s Info-évaluation service at 450 463-7177.

What is an assessment roll?

A property assessment roll is an inventory of all properties (buildings and land) within a municipality's territory. This inventory lists the properties according to categories, and includes their characteristics, value, and ownership details.

The assessment roll is primarily a management tool. It is used to determine actual property values for municipal and school taxation purposes. It is also a planning tool, as it provides a comprehensive and detailed picture of a municipality’s real property inventory.

What does the deposit of the roll mean?

It means the submission, by the Longueuil agglomeration’s Assessment Department, of the new municipal property assessments to the City Clerk’s Office of the municipality concerned. A new assessment roll was deposited in the fall of 2015 and is valid from January 1, 2016 to December 31, 2018.

Information session on the 2016-2018 valuation roll

The City of Saint-Lambert, in collaboration with the Direction de l’évaluation de l’agglomération de Longueuil (Longueuil Agglomeration Assessment Division), is inviting citizens to a general information session on the new valuation roll that was deposited for the years 2016-2018, on Wednesday, February 10 at 7 p.m. at the multi-purpose centre, 81 Hooper Street.

Individual meetings

Following the information session, if residents wish to receive personalized explanations about their property evaluations, they can meet with an evaluator, by appointment, to discuss their file. To make an appointment, citizens are invited to call the Longueuil Assessment Division, before February 12, at 450-463-7100, ext. 4986.

How is a building value established?

The value is based on the actual exchange value of a building in an open and competitive market at a predetermined reference date. This value therefore represents the most likely price that would have been for the building in a normal sale by agreement.

The assessor also uses a number of methods of assessment: the comparison method (based on the selling prices of similar buildings sold), the cost method (based on the value of the buildings, improvements, and the land), and the income method (based on the building’s estimated present and future revenue-generating capacity, when the building is a rental property).

What happens when you make modifications to your property?

When major modifications are made, they are likely to change the value of your property. In this case, a representative of the Assessment Department will visit your property to update its information. Regular maintenance work, a new coat of paint, or new carpeting do not increase the value of your property.
