Approximately $155,000 + Delivery (approximately $3000, covering pickup from the site to delivery within Collingwood Town limits). *Craning costs are additional.
Privacy: The ARU is designed to enhance privacy through the strategic placement of windows. By avoiding any openings on the back facade, we can help maintain visual privacy from neighbouring homes. Additionally, all our units come with pre-installed adjustable blinds, which not only protect against harsh sunlight but also act as a visual privacy barrier. Our wall, floor, and roof systems use spray foam insulation, which is excellent at absorbing sound. The windos and doors are all double glazed and filled with argon gas, further improving sound insulation. Utmost care is taken to seal all openings to prevent any leaks.
Context: The unit facade can be customized to match the architectural context of the site. The materials, finishes and textures can be adapted to blend with the existing dwelling units thus integrating with the surrounding neighbourhood.
Green Building and Design: The building envelope design utilizes strategies such as an opitmal glazing ratio, higher R-value insulation, prevention of thermal bridging, etc. to reduce energy consumption. Our units feature a 96% efficiency-rated energy recovery system that handles heating and cooling needs year-round. We are committed to sustainability by using eco-friendly and sustainable building materials throughout the construction process, further reducing our environmental impact. Additionally, since our units are built on a factory assembly line, there is very little material waste compared to conventional construction practices.
Accessibility: Our units are designed to adopt to special accessibility needs. The layout allows for various ingress points and can accommodate wheelchair access if needed. We are strong advocates for universal design, and the spaces we create can be customized to suit various needs. Elements such as the lighting system, switches, and height requirements, etc. can be adjusted to make the space more user-friendly.

Context:Every Quality Homes Suite is designed with an elevation A or B, one being a traditional style and one being a modern style, to ensure the context of the proposed ADU in relation to the existing dwellings and materials is consistent.

Important Notes for Property Owners
Design pre-approvals are intended to simplify the decision process for the property owner and expedite building permit approval timelines. Pre-approved designs do not imply compliance with the Town’s Zoning By-Law because full compliance is property-specific. Property owners will be required to go through the regular permitting process for the construction or placement of the ARU. For more information on Zoning By-Law Requirements visit the Rapid ARU Program webpage and scroll down to “ARU in a Detached Accessory Building – Zoning By-Law Requirements”.
The Town makes no guarantees, representations or warranty with respect to the ARU design or construction plans, including their quality, safety, or suitability for a homeowner’s property. Homeowners using pre-approved plans rely solely upon the designer, architect and/or contractor for any representations, warranties, and assurances with respect to the ARU design and construction plans.
While the Town will help make connections between property owners and the firm/designer, any agreements and/or financial transactions will take place directly between the property owner and the designer, architect and/or contractor.
Browse designs Explore our growing catalog of pre-approved detached ARU designs above. Review the images and details to find a design that is suitable for your needs and site.
Select a design Once you choose a plan, connect with the designer. The designer can guide you through the next steps, including what information you’ll need to start the permitting process.
Apply for a zoning certificate Use the online portal to apply for a Zoning Certificate. You’ll need to include a site plan that shows the pre-approved ADU on your site. This allows the Town to review zoning, drainage, and other site-specific factors. If your property is located within the Nottawasaga Valley Conservation Authority (NVCA) or the Grey Sauble Conservation Authority (GSCA) regulatory areas, additional permitting from those organizations may be required.
Apply for a building permit Once you have your Zoning Certificate (and, if applicable, a Conservation Authority permit) you can apply for a Building Permit. By using a pre-approved plan, you may be able to get your permit within 5 business days. Expedited permitting can only occur with complete Building Permit applications.
The following items are requirements for all detached ARU building permits:
Zoning Certificate
Stamped and signed drawings
EEDS form
P. Eng. site specific slab on grade/frost wall foundation designs where required
Minimum 1.2m setback required to all property lines
Utility connection
Glazing allowance (depends on site placement and may be limited)
In addition, the following items are required if applicable to your site:
NVCA/GSCA Permit (if applicable)
Heritage Permit (if applicable)
Separate septic approval required (if applicable)
Separate permit required for deck/exterior stair (if applicable)
Are you an ARU designer, architect or manufacturer?
