Home Addition Construction Services
CanaCore coordinates verified contractors to build home additions — main-floor extensions, second-storey additions, and in-law suites — with framing, structural work, and finishing supervised in the field from permit through final inspection.
Types of Home Additions
Main-floor and rear extensions, second-storey additions, garage conversions, and in-law or rental suites. CanaCore assembles and supervises the trades each addition needs — foundation, framing, envelope, and interior finishing — so the new space ties into the existing home cleanly.
From Plans to a Finished Addition
A successful addition ties new structure into the existing home so it is square, weather-tight, and code-compliant. CanaCore coordinates the sequence, checks the structural connections — backed by structural engineering where required — and supervises each trade through to the finished, inspected space.
Planning, Drawings, and Permits
This page covers building the addition. For the design and permit side — addition plans, renovation drawings, and permit-ready documentation — see Home Addition Plans & Renovation Drawings.
Our Process, from Permit to Final Inspection
A home addition follows a set path: a site review and scoped estimate; permit-ready drawings and municipal submission; foundation and framing that tie into the existing home; envelope, mechanical, and interior finishing; inspections at each hold point; and a final walkthrough. CanaCore supervises the trades at every stage.
Permits and Inspections
Additions are fully permitted, inspected work. CanaCore coordinates the permit drawings and submission, books the building, framing, insulation, and final inspections, and keeps the addition aligned with the Ontario Building Code so it passes and can be occupied.
Schedule, Quality Control, and Handover
CanaCore holds the schedule, sequences the trades so the addition is weather-tight before interior work begins, and checks the structural connections and finishes against the drawings. At completion you receive the inspection sign-offs and any trade warranties, and a finished addition that ties into your home cleanly.
