Building Permits

A building permit gives you legal permission to start construction on a building project. The building permit process helps enforce the requirements of the Ontario Building Code and the Municipal Zoning By-law. It ensures compliance during construction as well as the structural safety of the completed building.

All permits need building plans and a site plan. Others may need proof of entrance approval, conservation authority approval, septic or water and sewer approval, and/or payment of development fees.

Apply for a building permit

Before you start construction of any type, please contact the Building department to find out if you need permit.

All documents being submitted to the Municipality must be in their intended format, pictures of completed documents will not be accepted.

A complete building application will include a completed application, site plan and technical drawings.  Additional documents may be required depending on the nature of the proposal.

Building without a permit is against the law and you can't begin any construction until you've received permit approval.

If you begin building without approval, you or your contactor could be subject to fines or penalties as set out in the Ontario Building Code. Building permit applications can be picked up at the Building Department. The Municipality of Trent Lakes uses Cloudpermit to manage all applications. Instructions on how to use Cloudpermit are found at https://www.trentlakes.ca/build/cloudpermit/ 

Demolition permits

Homeowners are responsible for ensuring that a permit is obtained before demolition of any building begins.  If a demolition permit is not applied for and a replacement structure is submitted, the Municipality may not be able to verify previously existing structures and not be able to approve the site plan. Demolition permits are also necessary for adjusting your properties assessment value.

Frequently asked questions

Review the frequently asked questions related to getting a building permit. Please contact us if you have a question about your new building or renovating project. We are happy to assist. 

A building permit is a license that:

  • grants legal permission to start the construction of a building project
  • Gives building officials the means to enforce the requirements of various standards

Building permits are required to:

  • Ensure that construction within our municipality meets with standards set out in the Ontario Building Code
  • Ensure that zoning requirements, fire and structural safety standards and other building standards are met

Some of the projects that require a building permit include:

  • Construct a new building
  • Add an addition or make structural alterations, renovations or repairs to an existing building
  • Change a building's use
  • Make new openings for, or change the size of, doors and windows
  • Build a garage, balcony or deck
  • Excavate a basement or construct a foundation
  • Install new or modify existing plumbing systems, replacement of taps, sinks, toilets, or shower fixtures do not require a permit
  • Install or reconstruct chimneys or fireplaces
  • Build an accessory shed larger than 15 square meters
  • Any structure including a deck, gazebo or guest cabin greater than 10 square meters.  See the bullet above for accessory sheds. 
  • Wood burning stove/fireplace installation
  • Build a basement entrance
  • Finish an existing unfinished basement
  • Install a sign

Often, designers or contractors will get permits on your behalf, but homeowners are ultimately responsible for ensuring that a building permit is obtained before construction begins.

Some of the projects that do not need a permit include:

  • Replace existing doors and windows (same size), subject to distance from property lines
  • Install siding on small residential buildings, subject to distance from property lines
  • Build a utility shed under 15 square meters- zoning setback requirements still apply
  • Re-shingle a roof
  • Dry-wall or plaster
  • Paint or decorate
  • Install kitchen or bathroom cupboards

If you do not receive a building permit, the work may not comply with Ontario Building Code. This could result in: 

  • Costly repairs may be required to gain compliance
  • Removal of work that isn't in compliance
  • The building permit application fee may be increased based on administrative penalties found in our Fees and Charges By-law under Schedule B
  • Legal action may be initiated by the Planning and Building Services Department to gain compliance

The following individuals can apply for a building permit:

  • The property owner
  • Contractor or designer with appropriate authorization from the property owner

To design houses and make submissions to Ontario municipalities for building permits for home renovations, one must be a licensed architect, a Professional Engineer with a Certificate of Authorization from the Professional Engineers of Ontario (PEO), or accredited as a house designer by the Province with a Building Code Identification Number (BCIN). To obtain this accreditation, one must study and pass exams with specific focus on specialized areas of design, law, and building technologies related to single-family homes.

Property owners are also allowed to design for projects on their property, but the drawings must comply with the Ontario Building Code.

Please refer to Schedules B and H in the Fee and Charges By-law.

Construction or demolition must start within 12 months from when we issue the permit. Failure to do so could result in the revocation of the permit. Construction or demolition must not be substantially suspended or discontinued for more than one year. Suspension or discontinuation could result in the revocation of the permit.

According to the Ontario Building Code processing times can vary depending on project type. As a general rule, permits are issued within 10 business days for most home renovation projects. Time is counted beginning on the day after a permit application is received and only after all required information (i.e. plans, drawings, authorizations) has been received in our office.
