How the Waterloo Building Permit Process Works
Every building permit in Waterloo is reviewed against the Ontario Building Code and the City’s zoning by-law. Because Waterloo is part of the Region of Waterloo, some projects require coordination with the Region for water and sewer servicing. Ontario legislation targets a 10-business-day review for houses once a complete application is filed, so a complete, professional first submission is the fastest route to approval.
- Zoning check - we confirm setbacks, height, and lot coverage before drawing a single line.
- Drawing preparation - your complete, Waterloo-formatted package, typically in 5–10 business days.
- Submission - we file through the City’s online permit system and respond to examiner comments.
- Permit & inspections - you build, with City inspections through to final sign-off.
Second Units & Garden Suites in Waterloo
Under Ontario’s housing legislation, up to three residential units are permitted as-of-right on most Waterloo lots - a main dwelling plus two additional residential units, such as a basement apartment and a garden suite. A building permit and inspections are still required, and the drawings must show fire separation, egress, ceiling height, and independent ventilation. We prepare complete second-unit packages so your rental is fully legal and insurable.
What’s Included in Your Drawing Package
- Site plan based on your legal survey - setbacks, lot coverage, and parking
- Existing and proposed floor plans with dimensions
- Exterior elevations and building cross-sections
- Structural details and, where required, P.Eng-stamped drawings

Frequently Asked Questions
Do I need a building permit for a basement apartment in
Yes. Creating or legalizing a basement apartment (a second unit) in Waterloo requires a building permit with drawings showing fire separation, egress, ceiling height, and interconnected smoke and CO alarms. Ontario permits additional residential units province-wide, but the permit and inspections remain mandatory before the suite is legal.
How do I apply for a building permit in
Applications are filed through the City of Waterloo online building permit system. Ontario Design Studio prepares your complete drawing package, submits the application, and manages examiner comments and any resubmissions as part of our service.
How long does a building permit take in
Ontario legislation targets a 10-business-day review for houses once a complete application is received. Incomplete or non-compliant drawings reset that clock, which is why a complete, professionally prepared first submission matters.
Can I create a legal rental unit near the universities in Waterloo?
Yes, but student rentals in Waterloo often involve rental licensing or lodging-house rules in addition to the building permit. We prepare code-compliant drawings for the additional unit and help you understand which approvals apply.
