Ontario Design Studio provides BCIN-certified building permit drawings across the City of Richmond Hill, from the established streets of Mill Pond and South Richvale to the growing communities of Oak Ridges and Jefferson. We work with Richmond Hill’s zoning by-law every week and understand the added review that comes with building on the Oak Ridges Moraine.

Richmond Hill Local Considerations
- Oak Ridges Moraine: parts of Richmond Hill fall within the Oak Ridges Moraine Conservation Plan area, which can add environmental setbacks and conservation authority review.
- Mature neighbourhoods: infill and additions in areas like Mill Pond and South Richvale must respect established-neighbourhood character and tree-protection by-laws.
- York Region servicing: water and sewer connections are coordinated with York Region for many new builds and second units.

How the Richmond Hill Building Permit Process Works
Every building permit in Richmond Hill is reviewed against the Ontario Building Code and the City’s zoning by-law. Because Richmond Hill is part of York Region, 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, Richmond Hill-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 Richmond Hill
Under Ontario’s housing legislation, up to three residential units are permitted as-of-right on most Richmond Hill 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
- Energy compliance (SB-12) and Schedule 1 designer information
- Zoning summary confirming conformity with the Richmond Hill by-law

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 Richmond Hill 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 Richmond Hill 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.
Does the Oak Ridges Moraine affect my Richmond Hill permit?
It can. Properties within the Oak Ridges Moraine Conservation Plan area face additional environmental and site constraints and may require conservation authority approval. We confirm whether your lot is affected and prepare the drawings and supporting documentation accordingly.
