Whitby Deck Builder · Reformity Inc.Deck Builders in Whitby
Whitby draws a clear line for decks: more than 0.6 m (2 ft) above the ground needs a building permit, lower ones don't, and every deck has to meet zoning. On lots that slope toward the Lynde or Pringle Creek valleys, a deck off the main floor is often well past that height. The Fence By-law also covers privacy screens: they must sit at least 0.6 m from side and rear lot lines, and on a raised deck the deck and screen together can't exceed 3.5 m.

Drawn before we build
Drawn before we build in Whitby.
Every deck starts with a framing plan, footing layout, and guard and stair details sized for your yard. When your city requires a permit, the drawing set goes in with the application and the inspector checks the build against it.
Decking permits in Whitby
A deck more than 0.6 m (2 ft) above the ground needs a Whitby building permit, so we prepare the construction drawings and site plan, handle the application, and check whether a CLOCA permit is also needed when the lot is in a regulated area.

Where Ontario's Building Code requires a BCIN-qualified designer or a professional engineer for permit drawings, that sign-off is part of the drawing set.

Private trees
Whitby requires a Tree Removal Permit for private trees only in listed areas: the Brooklin and Werden's Plan heritage districts, woodlots of 0.2–1.0 ha, Tree Preservation Plan areas, residential lots of 2.02 ha or more, and natural or hazard lands mapped in the Official Plan. Town street and park trees are protected.
Town of Whitby: tree by-lawsConservation areas
Lynde Creek and Pringle Creek run through Whitby inside Central Lake Ontario Conservation's (CLOCA) watershed. Building, grading or filling in a regulated area can need a CLOCA permit first under Ontario Regulation 41/24, so we check CLOCA's regulated-area map before designing.
CLOCA: inquiries & permitsDeck permits
Whitby requires a building permit for any residential deck more than 0.6 m (2 ft) above the ground. Lower decks need no permit but must still meet zoning rules. We prepare the drawings and handle the application.

Whitby Decking FAQ
Quick answers.
Only if it's more than 0.6 m (2 ft) above the ground; a lower deck needs no permit but still has to meet zoning. In the Brooklin and Werden's Plan heritage districts, a rear-yard deck under one storey also skips the heritage permit as long as no trees come out.
