Building permits are issued when the plans for construction comply with the Ontario Building Code, the Southwest Middlesex zoning by-law and other applicable laws and regulations. Building permits allow municipalities across Ontario to ensure that proper building standards are met. The enforcement of the building code serves to protect the health, safety and welfare of the public.

How to get a building permit
You can apply online for your permit!
Southwest Middlesex is pleased to offer residents, builders and the business community Cloudpermit - an online system to apply for and track your building permits. The Cloudpermit building permit system allows you to apply for and to see the status of your application anywhere, anytime. You can start an application and finish it later plus receive email updates on the status of your permit application. You can even request building inspections!
To get started, check the helpful information below:
- How to Submit a Building Permit Application
- Getting Started with Cloudpermit manual
- Cloudpermit Support
- Cloudpermit - login and create an account
- To avoid delays, be sure to have a complete application with all required documents when submitting your building permit application. Incomplete applications or plans will sit in a pending status.
- Do not start construction until you have your permit. If you start work without a permit it can lead to delays, increased permit fees or legal action.
Applications are processed as quickly as possible. The complexity of the application, the completeness of the information submitted, including drawings, and referrals to other departments, if required, will affect the time it takes to review the application. If a zoning amendment or a minor variance is necessary, or if the building plans must be altered to comply with building codes, any required changes must be approved and finalized before the building permit can be issued.
- Upon all reviews being completed additional permits may be required (ex. water meter connection, sewer connection, right-of-way work permit)
- a building permit is issued to the applicant for payment upon approval of the proposed construction
- construction must proceed as approved by the building inspector
- inspections will be required throughout the project at each major phase of construction - these will be carried out by the SWM Building Inspector
- full details of the review process can be found in the SWM Guide to Building Permits document.
The inspector's duty is to ensure that the project is being carried out according to the Ontario Building Code, the building permit and the approved building plans. The individual responsible for the project must request each inspection with 48 hours advance notice to the building inspection department. If the building inspector finds that some work does not conform to the approved plans or code, the owner will be advised - possibly with an order - that the situation is to be remedied. If the violation is deemed serious enough, the building inspector may post a stop-work order which will be in effect until the problem is resolved. If work on the project continues without resolution of the problem, legal action may be taken against the builder/owner.
The builder must also bring any proposed deviations from the original plan to the attention of the building inspectors so that they may be approved or rejected in the same manner as the original building plans,
Swimming Pools & Fences
Every swimming pool with a depth greater than 600 mm requires a permit
All swimming pools must be fenced for safety - see the swimming pool fence by-law for full details including gate/door requirements.
A building permit is required for a tent that is greater than 60 square meters (645 square feet)
- tents greater than 225 square meters (2,421 square feet) must have the tent framing and anchorage system designed and the installation inspected by a professional engineer
- all tent fabric must comply with CAN/ULC-S109 or NFPA 701 flammability standards.
Inspection information will be provided with all permits
Please ensure that inspection requests are made at least 48 hours in advance.
Inspections are generally conducted in the afternoon.
