Building and Renovating
Welcome to the South-West Oxford Building Department
A building permit is a document which grants legal permission to begin construction of any new structure, addition, or renovation. A permit is issued only when the plans for construction comply with the Ontario Building Code, South-West Oxford’s Municipal By-Laws, and other applicable laws and regulations. Building permits are necessary to ensure that zoning requirements, fire and structural safety standards, and other building standards are met (primarily for health and safety reasons). It is the building and or property owner's responsibility to ensure that a building permit is obtained when required. For more information, see the Building By-Law and the amended Schedule A: By-law 12-2023.
The Building Department is an administrative division of the Township that enforces the Ontario Building Code Act and Regulations. The Ontario Building Code (OBC) is a regulation that is set by the province, and the Township is the administrator of the Regulations. The OBC was last updated in April 2025. For news and updates regarding the OBC, see the following link: Building Code Updates. For email notifications about Code News, see here.
The Permit Process
The Township uses Cloudpermit, a cloud-based software, for the preparation and issuance of all building permits. We are pleased to offer this service to residents, builders, and our business community. This building permit system allows you to apply for and to see the status of your building (and septic system) permit application anywhere, at any time. You can start an application and finish it later, receive email updates on the status of your permit application, and even request an inspection.
A complete building permit must include the following (upload your supporting documentation as an attachment directly on Cloudpermit):
- Completed permit application form - signed-off and submitted
- Completed schedule 1 form/designer form (if applicable)
- Drawings (must be legible and clearly show construction details to scale)
- Site plan (must be fully dimensioned showing all overall dimensions of property, all buildings with dimensions on the property, and distance to property lines from all buildings/structures, and full lot coverage calculations)
- Sourcewater Protection Screening Form
- Owner authorization letter allowing the applicant to act as the owner’s agent if applicant is not the owner
- Zoning By-law Compliance Form - Applicable Law Declaration - which includes authorization/approval from any applicable authority having jurisdiction. i.e. UTRCA, Ministry of Transportation etc.

The process of obtaining a permit is to protect the health and safety of the public for the duration of the building’s life.
