Architectural Drawings & Building Permits in Windsor
Building in Windsor comes with its own set of conditions: a high water table, heavy clay soils, a lot of older housing and a border-city real estate market that keeps people investing in their homes. If you are planning a custom home in South Windsor, an addition in Riverside, or a second unit in an older house in Walkerville or Sandwich Town, Proventa Construction can prepare the architectural drawings in Windsor that your project needs. We also produce complete permit drawings that meet the Ontario Building Code and the City’s zoning requirements.
Basement flooding is a real concern across Windsor, so our drawings pay attention to drainage, sump pump locations, backwater valves and foundation waterproofing instead of leaving them as an afterthought. If your property is in Walkerville, Sandwich Town or another area with heritage character, we also look at how exterior changes might be received. Properties near the Detroit River or in regulated lands may need Essex Region Conservation Authority approval as well.

Frequently Asked Questions: Windsor Building Permits
Key information about architectural planning, zoning reviews and building permits in Windsor, ON.
When do I need a building permit in Windsor?
A permit is generally required for new buildings, additions, structural alterations, new or altered plumbing and HVAC systems, finished basement units, and many decks. Accessory buildings under 10 square metres (about 107 sq. ft.) typically do not need a building permit, though zoning rules still apply.
How long does the permit process take?
Once your application is complete, the review period for a house is governed by Ontario’s legislated timelines, roughly 10 business days. Delays usually come from missing drawings or unanswered comments, which we try to prevent.
Can I legally rent out my basement in Windsor?
Yes, if the space meets Building Code and zoning requirements and has the proper permit. Egress, fire separation, ceiling height and smoke and CO alarms are the main areas inspectors check.
Will flood protection be included in my drawings?
We show drainage, sump and backwater valve details where they apply and coordinate them with your plumber. Given Windsor’s history with basement flooding, we think it is worth planning properly.
What if my property is in a heritage area or near the river?
Some properties need extra approvals, such as heritage review or Essex Region Conservation Authority sign-off. We identify these at the start so they do not hold up your build.
