2026 Property Taxes

Petrolia sets its local municipal levy annually. Property-tax bills also incorporate County of Lambton and education components. Verify the current 2026 residential rate directly with the Town before calculating ownership costs.

Zoning & Building Permits

Confirm zoning before planning additions, accessory structures, additional units or a change of use. Building, plumbing and septic approvals in much of Lambton County are administered through County planning and development services.

Additional Residential Units

Provincial housing policy has expanded ARU permissions, but a specific Petrolia property must still satisfy current zoning, parking, servicing, Building Code and fire-safety requirements.

Buyer Due Diligence

  • Confirm zoning and permitted uses.
  • Review municipal water and sewer servicing.
  • Check permit history.
  • Investigate heritage or historic oil-development constraints where relevant.
  • Verify taxes and local charges.
