Renovation Contractor in Oshawa & Durham Region
Clarington isn't one housing market — it's several. Newer subdivisions in Bowmanville and Courtice tend to have straightforward building conditions; older homes in Newcastle and the rural hamlets often need a different approach. We treat these as genuinely different projects.
Clarington at a Glance
Before We Design Anything
Clarington's current Zoning By-law 84-63 sets your setbacks today, but the Municipality is finalizing a new consolidated by-law with different standards for setbacks, lot coverage, and accessory buildings. We confirm which version applies to your property, and which one will apply by the time your permit is issued.
If your addition includes a basement or a secondary suite, see our legal basement apartment guide for Durham Region — the parking and unit-count rules there are separate from what applies to a straight addition or garage.
Building Up
Adding a full floor on top of your existing home isn't just framing walls — it changes the structure underneath it too.
How It Works
An addition isn't just built — it's checked against your zoning, engineered, permitted, and inspected. We carry all of it.
We check whether your property falls under the current By-law 84-63 or the new zoning by-law once it takes effect, and what that means for your setbacks.
Scaled plans plus structural engineering where required — mandatory for any second-storey work.
Filed through the Service Clarington portal, with staged inspections built into the schedule from the start.
Framing, structural, electrical, and plumbing inspections through to final sign-off.
Our on-time guarantee. If we miss the agreed completion date for reasons within our control, you're compensated $300 for every day past it — part of the Certainty Stack on every Cornerstone build.
Why Build It Permitted
A permitted addition shows clean on a title search. An unpermitted one can hold up your sale or force disclosure to buyers.
Unpermitted structural work can void your coverage if something goes wrong down the line — permitted work protects your policy.
The Municipality can order unpermitted additions removed or brought up to code after the fact. Done right the first time, that risk doesn't exist.
Proper engineering means your addition holds up for decades — not just long enough to pass a first inspection.
