NEWMARKET'S TRUSTED BASEMENT RENOVATION COMPANY

Basement renovation in Newmarket, street by street

Newmarket mixes mature neighbourhoods around historic Main Street with newer communities like Woodland Hill and Summerhill — older basements often need moisture and egress work designed in first, while newer builds finish quickly into theatres, gyms and suites.

With York Region rents climbing, a legal Newmarket basement suite is a serious income play. Whatever your starting point, we turn that lower level into finished, livable square footage — and real value added to your Newmarket home.

PERMITS & APPROVALS · NEWMARKET

Basement renovation permits in Newmarket, handled for you

Newmarket requires a building permit before a basement is finished or converted into an additional residential unit, with staged inspections through construction. Under Ontario's updated housing rules, additional units are permitted on most urban residential lots subject to the town's zoning, and suites must meet Building Code and Fire Code requirements. We prepare the drawings, file the permit, and manage every inspection to final sign-off.
