LaSalle Ontario Property Guide
LaSalle includes established suburban neighbourhoods, newer development, Detroit River influences, wetlands and significant natural areas. Buyers should verify zoning, servicing, flood/conservation constraints and permits for any planned renovation or additional unit.
2026 Property Taxes
LaSalle Council’s amended 2026 budget resulted in a reported 3.47% increase in the LaSalle portion of taxes for the average single-family home, or about $109.99 annually. The Town states that 2026 tax rates are approved under By-law 2026-033. Confirm the final property-class rate and assessment for a particular home.
Zoning & Building Permits
LaSalle’s Comprehensive Zoning By-law regulates permitted uses, setbacks, lot coverage and additional residential units. Building permits are required for new dwellings and many additions, alterations, basement conversions and accessory structures. Natural heritage, drainage or conservation review may also affect some properties.
Additional Residential Units in LaSalle
LaSalle’s zoning framework permits up to two attached ARUs within a qualifying single-detached, semi-detached or street-townhouse dwelling where the applicable zone permits them. Alternatively, one detached ARU may be permitted on the same lot in qualifying circumstances.
A detached ARU is limited to a maximum of 100 m² or the gross floor area of the main dwelling, whichever is smaller. The primary dwelling and ARU must be connected to full municipal sanitary sewer and water services, and the detached unit must be on a permanent foundation. Additional zoning and access requirements apply.
Property records, compliance and servicing checks
Work Order and Zoning Compliance Letter: LaSalle provides a formal property-specific request for work-order and zoning compliance information. This is useful when legal use, zoning compliance or unresolved municipal work affects a purchase.
Building and occupancy records: Through Routine Disclosure, the Town can release building permits, residential building drawings/plans, occupancy records and relevant survey information to the property owner, an authorized agent or another person with written owner permission. Planning application files can also include zoning amendments, consents and minor variances.
Public Works and septic checks: LaSalle’s disclosure program also identifies Public Works legal letters, work-order status, municipal drainage mapping and water-consumption records. The Town’s current fee schedule includes Part 8 septic-system permits and a septic compliance review, so private-servicing history should be checked where applicable.
