Working on a heritage residential house is very different from modern construction. Heritage properties are protected under municipal and provincial regulations, meaning any alteration, addition, renovation, or restoration must follow strict heritage guidelines, zoning bylaws, and Ontario Building Code requirements. Even minor changes may require specialized drawings, approvals, and permits.
At ITI Permit, we provide Heritage Drawings and Permits services for heritage-listed and heritage-designated residential houses across Hamilton, Stoney Creek, Niagara Falls, Waterdown, Toronto, Brampton, Oakville, and throughout Ontario. Our BCIN-certified team helps homeowners, builders, architects, and contractors navigate the complex approval process without risking rejection, delays, or penalties.
