Garden Suites in Oakville: What Is Different Here

Oakville sets additional residential unit permissions through its zoning by-law, administered by the Town’s planning and building departments. Start at Oakville planning and development and confirm what your specific lot allows before design.

  • Big lots, big trees. Oakville has some of the deepest residential lots in the GTA, particularly in Old Oakville, Bronte, Southeast Oakville and Morrison. Space is rarely the constraint. Mature tree canopy usually is, and Oakville takes its private tree by-law seriously, so an arborist report and tree protection zones are a normal part of the process here rather than an exception.
  • Heritage areas. Parts of Old Oakville and Bronte sit in or near heritage conservation districts. A detached structure visible from the street in those areas attracts additional review, which affects both design and timeline.
  • Creek and conservation lands. Sixteen Mile Creek, Bronte Creek and Joshua Creek bring Conservation Halton regulation to a lot of properties. If your rear yard runs toward a valley, the regulated area is checked before the suite is sited.
  • North Oakville is newer and tighter. The newer communities north of Dundas have shallower rear yards, so the feasibility check there is the same as in new Milton.

Garden Suite Pricing in Oakville

With our optimized building process, all-in construction expenses stay highly efficient, ranging from $350 to $600 per square foot based on your choice of footprint:

  • Small Suites (300-600 sq. ft.): $450 to $600/sq. ft.

  • Personalized Architectural Design: Drafting unique layouts that fit seamlessly into your backyard landscape.
  • Engineering & HVAC Plans: Verifying all structural and environmental safety standards match the Ontario Building Code.
  • Oakville Permits & Zoning: Obtaining town approvals, necessary tree protection reviews, and site clearances.

Regulations for Building Garden Suites in Oakville

Garden suites, also known as Additional Residential Units (ARUs), are self-contained dwellings located on the same lot as a principal residence. While Oakville supports the concept of ARUs, specific regulations for detached garden suites are not explicitly defined in the current zoning by-laws.

General Provisions for ARUs:

  • Unit Type: ARUs are typically permitted as secondary suites within single detached, semi-detached, or townhouse dwellings.
  • Exceptions: Construction may be restricted in floodplain areas or where conservation authority regulations apply.
  • Parking: Parking requirements vary depending on the location and the number of existing units on the property.

For more information and guidance on ARU construction, consult the Town of Oakville’s Planning Services or refer to the Property Standards By-law.

Personalize Your Garden Suite Design

Customize your garden suite with a variety of personalized finishes, including siding materials, windows, doors, and flooring. While the overall size and layout—such as walls, doors, and room locations-must meet Oakville’s regulations and remain unchanged, you can still add unique touches to make the space your own.

I just completed an extensive house Reno with Dmytro and his team and I couldn’t be happier. Deomax got a tremendous amount of work done in a relatively quick time frame and he was ahead of schedule. We weren’t the easiest customer in the world and there were many jobs that came up and extended the scope of work. Outside of the quality of work and timelines, the biggest thing I was impressed with was how much care and detail Dmytro put into the project. Any additional work or issues that came up were explained in great detailed, he guided us without being pushy, he allowed us to make the decisions but was a trusted advisor. It was our first time taking in a project like this, it shouldn’t wasn’t easy but Dmytro and his team were a key reason it was a success. Easy 5 stars for me, would never hesitate to recommend him to anyone and I’m certain we will be using him for work in the future.

Deomax Group completed a full bathroom renovation in my home. From the first consultation right to the end of the renovation, Dmytro and his employees were concise, professional, and respectful. Dmytro listened to my vision, worked to make it happen and provided solutions and options for any disruptions/ surprises (which happens in old Toronto homes!). Because of Dmytro's professionalism & consistent communication he showed from the beginning, I felt confident to have him & his crew start our project while I was away for 2 weeks. He kept me updated throughout the progression, which was greatly appreciated. Dmytro & his employees take pride in their work and it shows in the quality. Home renovations can be very personal with unique visions & preferences. I think Dmytro understands this and will seek out the best employee for the task, ie: tiling, trim work, ect. When I had questions along the way of the renovation, Dmytro and his employees took the time to listen and answer them. To sum this all up, choosing Deomax Group to complete my bathroom renovation in 4 weeks, was a very pleasant experience. I'll definitely be using them for future home renovation! ***UPDATE 1.5yrs LATER*** I am pleased to update this review. Deomax had called me recently to simply check in on the quality and performance of my renovated bathroom. To which there were a couple mishaps that I thought I would have to live with or get fixed on my own. I explained an issue with my sink & Dmytro listen and suggested a solution and it worked! Also, one of my baseboards on an exterior facing wall had cracked due to weather change. This I thought I'd just have to live with. Again, Dmytro provided a solution and came and fixed it within a week! If Deomax did not have do a quality check service call, (1.5 years later!) I would still be dealing with this issues today! Thank you Deomax & Dmytro for the excellent service & quality of work!

Dmytro looked after a major renovation for a 100+year home in the Birch Cliff area in the east end of Toronto. Was able to come up with some cost savings strategies and finished the job ahead of schedule. Challenging job that was successfully completed 👍🏻👍🏻

We selected Dmytro and his team after several interviews with potential contractors for our home renovation. As part of our initial quote, he shared several innovative and cost savings ideas for our project. During the project, communication was always on point and prompt. His team was always punctual and tidied up daily, which was appreciated, we were living in the home during the renovation. With Dmytro, there were no unexpected changes to the quotes, and we were always informed and aligned on changes. We were pleased with the quality of the work and will use Deomax for future renovations,

Deomax helped us with a bathroom renovation this fall. Dmytro and his team did a great job, started and finished on time and the attention to detail was much appreciated. Dmytro is great at responding to any questions and is very passionate about his work. There was a little hiccup during the demolition, but it was addressed quickly and handled professionally.

Deomax Group Testimonials

We had the guys from Deomax redo our kitchen for us and we could not be happier with the work.

We have a more modern kitchen now that is far more functional than our old design.

I called Deomax to help me with our basement, and I am so glad that I did. They gave us an incredible and beautiful space.
