Planning and Development

We work with the seven member municipalities in Northumberland, the Government of Ontario and local residents and businesses to grow communities and protect resources in Northumberland.

Development applications

Contact us if you need to apply for a development application.

County Official Plan amendment

Amendments to the Official Plan are required when a new development does not satisfy the intended land use categories or policies in the plan.

Municipal Official Plan amendment

Our seven member municipalities have Official Plans that detail land use categories and establish local policies to manage growth and development.

  • Add land to a neighbouring property (lot addition)
  • Establish a right to use another property (easement)
  • Establish permissions for mortgaging or leasing parts of lots

Review fee


Zoning by-law amendments

Our seven member municipalities each have their own zoning by-law. Zoning by-laws control the use of land and often include land use restrictions (permitted uses) and technical provisions (setbacks, lot size requirements, etc.).

Amendment to a zoning by-law

If you require a zoning by-law amendment, contact the appropriate municipality. You may require an amendment to a zoning by-law if your proposal doesn't meet the permitted uses outlined in the existing by-law. We review some zoning amendment applications for the member municipalities.

Review fee

$250 to $500

Minor variance

A minor variance is a minor adjustment to a municipal zoning by-law. Contact the appropriate member municipality if you require a minor variance application. We review some minor variance applications for the member municipalities.

Review fee


Site plan

Member municipalities use site plan control to ensure a development meets the official plan policies, zoning by-laws and design guidelines. Site plans detail how a property will be developed. We review some site plan applications for the member municipalities.

Contact the appropriate member municipality if you require site plan approval.

Countywide development charges

Development Charges (DCs) are one-time fees levied by municipalities on new residential and non-residential lands. The purpose of DCs is to ensure that new development pays for the infrastructure growth (such as road improvements, new facilities and other infrastructure) that is required to meet the needs of the growing community. These charges apply to all County services on a countywide basis with the exception of Waste Diversion – Curbside Collection, which applies in the benefitting service area only (outside of Port Hope Rural Ward II).

At the August 25, 2021 meeting of County Council, Council passed By-law No. 25-2021 to amend municipal-wide development charges By-law No. 2020-36. Any person or organization may appeal to the Ontario Land Tribunal under section 14 of the Act, in respect of the development charges by-law, by filing a notice of appeal setting out the objection to the by-law and the reasons supporting the objection to the Northumberland County Clerk on or before October 4, 2021.
