Apply for Additions & Conversion to Habitable Space

A Building Permit is required for additions to existing structures or conversion of non-habitable space to habitable space within residential buildings, commercial, institutional or industrial structures. Depending on the scope of the work, review from the Bureau of Planning may be required prior to submitting for a Building Permit.
