Property Taxes in Whitchurch-Stouffville
Property taxes are based on the property’s assessed value and applicable municipal, York Region and education tax rates. Use the Ontario Home Intel Property Tax Calculator for planning and confirm the current bill and assessment directly with the Town and MPAC.
Zoning and Property-Specific Due Diligence
Before buying for a specific use or starting construction, confirm the current zoning and any site-specific provisions. Rural properties may have additional considerations involving private servicing, agricultural uses, environmental features and conservation regulation.
Building Permits and Renovations
Renovations involving structural work, additions, plumbing, changes of use, new dwelling units and many accessory structures can require building permits and other approvals. Zoning compliance should be checked before relying on development potential.
See our Ontario Renovation Guides and Zoning & Permits hub.
Additional Residential Units in Whitchurch-Stouffville
Whitchurch-Stouffville has updated its zoning framework for additional residential units. The Town’s ARU initiative was designed to permit up to three dwelling units on fully serviced residential properties, consistent with provincial requirements. An ARU can include a secondary suite or a detached residential unit where the zoning and other requirements permit it.
Do not assume that the same permissions apply to rural or privately serviced properties. Servicing, zoning, parking, building-code and environmental constraints should be confirmed for the specific lot before relying on additional-unit potential.
See our Additional Rental Units in Ontario guide.

Whitchurch-Stouffville Property FAQ
Can a fully serviced residential property have three dwelling units?
The Town’s ARU zoning update was developed to enable up to three dwelling units on fully serviced residential lots, subject to the applicable zoning and other requirements.
Are rural properties treated the same way?
Not necessarily. Private servicing, environmental constraints and different zoning provisions can change what is permitted on rural properties.
Should I verify an existing basement apartment?
Yes. An existing kitchen, entrance or rental history does not by itself establish zoning, building-permit or other compliance.
