Legal Basement Apartment in Uxbridge
Can you legally rent out your basement in Uxbridge? Sometimes — and that word matters. Uxbridge is stricter than the rest of Durham. It wants two parking spaces, not one. And on rural land, conservation rules can limit or even block a suite. Better to know before you buy. Here's what Uxbridge asks for, in plain words.
Three Things to Clear First
Check These Before You Commit
On an Uxbridge lot — especially a rural one — three things decide whether a suite is even possible. All three have to clear before a permit, so we check them up front, before you buy or design.
Two Parking Spaces
Uxbridge needs two spaces for the suite, outside a garage — where most of Durham needs one. The lot has to physically fit them.
Conservation Land
Much of rural Uxbridge sits on the Oak Ridges Moraine or Greenbelt, where a suite can be limited — or, in protected areas, not allowed at all.
Septic Capacity
Not on municipal sewer? Your septic system has to handle the added load before a permit — an older tank may need an upgrade.

Rule Book 1 · Uxbridge Zoning
The Local Rules in Detail
These are the property-level rules an Uxbridge home must satisfy to add a legal Additional Residential Unit.
Parking — Two Exterior Spaces
- Minimum two parking spaces for the second unit, on top of the main home's — and they must be outside a garage, in a driveway or legal exterior area.By-law 81-19, ARU provisions
- This is stricter than the rest of Durham (most require one), reflecting Uxbridge's rural servicing and limited transit. It's the rule to confirm before buying a property for a suite.
The Driveway Limit
- The instinct is to widen the driveway for those two spaces — but Uxbridge limits driveway width and protects front-yard soft landscaping. You can't pave more lawn if it breaches your zone's coverage rules.By-law 81-19
- Fitting two legal spaces within those limits is the layout problem we solve before drawing plans.
Entrance Access
- An unobstructed access path must be maintained to the suite's private entrance, meeting your zone's side-yard setbacks. We design it into the plan so egress and clearances are covered from day one.
Rule Book 2 · Inside the Suite
What the Building Code Requires
Once the lot clears, the inside is governed by the Ontario Building Code — the same across Ontario. Here's what matters most in a basement:
The Essentials
- Ceilings at least 1.95 m (6 ft 5 in), dropping to 1.85 m under beams. Where the open floor is lower, it can be lowered to pass.
- Egress windows — a 0.35 m² clear opening in every bedroom, no dimension under 380 mm, with clearance in the window well.
- A 30-minute fire separation between your suite and the home above.
- Interconnected smoke and carbon-monoxide alarms — one sounds, they all sound.
- Minimum room sizes so the space is genuinely livable.
Permit & Registration
It Has to Be Registered
Building the suite to code is only half of it. Under Registration By-law 99-107, the unit must be registered with the Township — and it's an offence to advertise or occupy a suite without it.
A Multi-Agency Sign-Off
Registration under By-law 99-107 requires a review by four bodies before the two-unit house goes on the Township's public register:
On conservation land, written clearance from the relevant authority may be needed before the permit can even be issued. We carry the whole thing — from the conservation and septic checks to the final registration — so it's done once, properly.
Why Build It Legal
A Registered Suite Is Worth More
Real Income
In a commuter town like Uxbridge, a legal suite can carry a real chunk of your mortgage — with its own full bathroom built to standard.
Insurance & Resale
A registered unit is what insurers and buyers want. An undisclosed one can void coverage and scare buyers off.
Tenant Safety
Code fire separation, egress and alarms keep the people living there safe — and you out of liability.
No Surprises
Confirming parking, conservation and septic up front means no rejected plans, no rework, no order to vacate.
