Will it fit? Check your lot before you pay for drawings.
Enter your address. We pull the real lot, run the setbacks and coverage rules, and show which projects are worth pricing: garden suite, addition, multiplex, pool, or rebuild.
Catches the things that usually kill projects: rear-yard depth, lot coverage caps, the 1.0 m fire-access path, protected trees.
Real data 123 Bayswater Ave, run against the live engine: lot, existing home, buildable envelope, and unit potential.
What are you thinking of building?
Each one runs the same check against your address: setbacks, lot coverage, unit count, height.
Add an income unit
Garden suite, basement apartment, or multiplex. These have the most zoning constraints, and the most expensive surprises if you skip the check.
- Rear-yard depth & separation distance
- ADU footprint cap & storey limit
- 1.0 m fire-access path to rear
Build out or up
Addition or second storey. We check the interior side yard, rear setback, and your lot coverage cap.
Pool, cabana, or shed
Rear-yard limits, pool fence rules, and accessory-structure setbacks.
Tear down and rebuild
Buildable footprint, max height, max units, lot coverage, all before you offer.

A summary your contractor can read
Three different reasons to check an address.
Find out if your idea fits before you start calling people.
See which projects are realistic on your lot, then go into contractor calls knowing the setbacks, the coverage cap, and the unit limit already.
Check my addressLeads that already know the lot.
Homeowners arrive with their setbacks, envelope, and project fit already mapped. Less educating, more quoting.
Become a partnerScreen the upside before you price.
Buildable area, max units, and the constraints that move the deal, before the offer goes in.
Run a property checkA pre-check, not a permit
Zoned reads the City of Ottawa's zoning rules and your lot's real geometry to show what may fit. It is not a permit approval and not legal, architectural, engineering, or surveying advice. Verify with the city and licensed professionals before building.
