But a permit is required for structural alterations, an addition, changes or replacement of heating and plumbing systems, or excavation work. With basement finishing projects that include the installation of an entrance or chimney, as well as a partial or full underpinning, a permit is required.
The regulations and guidelines for obtaining a permit also require a home assessment to be completed by a certified inspector. This evaluation outlines the scope of the project, requires architectural drawings and measurements, and includes permit-related details. The paperwork required varies depending on the municipality.
A permit application also provides direct and indirect information on building by-laws, trade codes, and zoning regulations.
