The Town of Innisfil offers building permits for homeowners, housing developers, and industrial, commercial and institutional developers looking to start certain building and renovating projects.

Building permits are necessary to ensure that zoning requirements, fire and structural safety standards, and other building standards are met. These standards are primarily in place to ensure occupants' safety.
