Building Permit Drawings in Ajax

Basement suites, rear additions and deck permits for Ajax homes — from the postwar streets near the lake to the newer subdivisions north of Highway 2.

A Commuter Town Where Homes Work Hard

Ajax is a GO-line town: many households commute, and many mortgages are offset by a basement tenant. The town's housing splits roughly by era — compact postwar homes in the south near the waterfront, and larger 1980s-to-2000s two-storeys further north — and the two need different things from a designer. We draw both: suite conversions that deal with older, lower basements, and finishing or additions in the newer stock.

Basement Second Suites

A legal second suite needs a permit from the Town of Ajax, and the application needs drawings: the unit layout, fire separation between dwellings, exits and services. We design the suite around what your basement actually offers and produce the full permit set.

Additions & Outdoor Structures

Ajax families who outgrow a house often extend it instead of leaving the neighbourhood — rear additions and reworked main floors are the town's staple renovation. We also prepare drawings for the simpler permits: elevated decks, porches and detached garages.

Yes. Elevated decks and similar structures need permits too, and the drawing requirements are real but modest — a site plan and construction drawings. We quote small projects proportionately.
