A Building Permit is your formal permission from the Township of Wellesley to begin construction, renovation, demolition, changes of use, and the installation, alteration, extension or repair of on-site sewage systems on your property. The Township of Wellesley Building Department is pleased to offer residents, builders, and the business community Cloudpermit - an online system to apply for and track your building permits.
Wellesley Building staff must review your plans to ensure that they comply with the Ontario Building Code and all other applicable law prior to the issuance of a Building Permit.
The Cloudpermit building permit system allows you to apply for and to see the status of your application anywhere, at any time. You can start an application and finish it later, and receive email updates on the status of your permit application. You can even request building inspections online using your smartphone or using any other online access point!
