Perth South, Ontario Property Guide
A practical 2026 guide to property taxes, zoning, building permits, rural development and buyer due diligence in Perth South.
2026 Property Taxes in Perth South
Perth South property taxes combine the Township rate, Perth County rate and provincial education rate. The applicable rate depends on tax class and MPAC assessment. Buyers should confirm the latest annual taxes from the current tax bill and lawyer’s statement of adjustments.
Zoning and Land Use
The Township zoning by-law implements local and County planning policy by regulating land use, building location, lot dimensions, setbacks, parking and other development standards. Agricultural properties can have additional restrictions affecting severances, residential uses, livestock operations and accessory buildings.
Building Permits
Perth South uses the City Reporter online permitting system. The Township states that permits are required for new buildings over 15 m², additions, renovations, demolitions, prefabricated structures, mobile homes, plumbing, heating and ventilation work, fireplaces, pools, decks, temporary buildings, farm buildings and changes of use.
The 2026 fee schedule took effect January 1, 2026. For example, the base fee for a new single-detached dwelling is $102 plus $0.66 per square foot, while renovations use the same $102 base plus $0.66 per square foot. Other permit types have separate fees.
Additional Residential Units and Second Dwellings
Perth South has amended its zoning framework over time to address second dwelling units and residential permissions in agricultural areas. Whether an additional residential unit is permitted on a specific property depends on zoning, servicing, building location, septic capacity and current County/Township policy. Confirm the current by-law before planning a secondary dwelling.
