Solarium / Building extension

Building extension

To build an extension of an existing home, a construction permit must first be obtained from the Urban Planning Department.

Applicable regulations

According to the municipal regulations, adding an extension to an existing residential building, such as a solarium or an additional room, must comply with applicable zoning, construction, and, where applicable, Site Planning and Architectural Integration Program (SPAIP) requirements. House extensions must follow specific rules outlined in the municipal by-laws:

Zoning By-Law No. 90-58: Chapter 3, 4 and 10

Permits and certificates By-Law No. 90-61: Chapter 4

Subdivision By-law No. 90-59

Construction By-Law No.90-60

Site Planning and Architectural Integration Programs By-Law No. SPAIP-2022-55

  • The SPAIP By-Law applies to all residential, commercial, industrial and institutional zones. It promotes consistency throughout the Town by ensuring that proposed projects integrate harmoniously with the surrounding neighbourhood.
  • ** Please note that the SPAIP review and approval process may take some time. Applicants should plan accordingly and allow sufficient time for the application to be reviewed before beginning their project.

Since several regulatory provisions may apply to a renovation project, the Urban Planning Department can help you understand the applicable requirements and guide you through the process.

Applying for a permit

Permit costs: Fees will depend on the nature of your project (please consult By-Law No. GEN-2026-51).

The "Online Permit Management" platform allows citizens to submit a permit application online, track its status, and in many cases, pay the required fees and obtain the desired permit/certificate without having to go anywhere.

All you need are your plans and other required documents in digital format (photos of documents are not accepted) and a credit card. The service is available 24 hours a day, 7 days a week.

To access the platform, you must first create a user account.

Online Permit Application

Your permit application can be submitted in person at Town Hall during regular business hours (17200 Hymus Boulevard, Kirkland).

To this end, we invite you to download and complete the permit application form, then submit it along with all required documents. Paper copies of the form are also available at City Hall.

Required documents

  • Certificate of location and site plan
    A copy of the property’s certificate of location and a site plan clearly indicating the dimensions of the proposed structure, its planned location and its distance from the property lines
  • Detailed construction plans
    Detailed electronic construction plans signed and sealed by an architectural technologist, an architect or an engineer, depending on the project, showing both the existing building and the proposed extension.
  • Samples
    Samples showing the exact colour and texture of the exterior materials that will be used.
  • Other documents
    Any other document i.e.. texts, maps, plans, architectural sketches, scale models, visual simulations, drawings or audio-visual material, which the applicant may deem appropriate in support for the request
  • Proxy
    If someone other than the homeowner is submitting the application, proof of authorization from the homeowner must be provided.

**With all reservations: Some situations may require additional documentation, including documents requested for SPAIP. Please contact the Urban Planning Department for further assistance.
