Terms of Service
Last updated: August 2026.
These terms govern your use of this website, operated by Second Dwelling Unit Ottawa. By using this site, you agree to them. For questions, contact info@seconddwellingunitottawa.ca or (343) 314-5115.
What this website is for
This site provides general information about Additional Dwelling Unit design, construction, and legalization services in Ottawa, along with a cost estimator tool. It is intended to help you understand your options and start a conversation with us – it is not a substitute for a site-specific feasibility review, and it does not constitute a quote, contract, or guarantee of any kind.
The cost estimator
The cost estimator on this site produces a range based on typical Ottawa construction rates by project type, current as of the date shown on the estimator page. It does not account for your specific property's conditions, servicing, or site access, and it is not a quote. A firm price is only provided in writing, following a feasibility review of your property.
No guarantees implied by this website
Nothing on this website should be read as a guarantee of project cost, timeline, permit approval, or outcome. Zoning review, permit approval timelines, and construction costs depend on your specific property and are confirmed in writing on a project-by-project basis. Any workmanship warranty applies only as set out in your individual written quote.
Project-specific terms
If you engage Second Dwelling Unit Ottawa for design, permitting, or construction services, those services are governed by the written quote and contract for your specific project, not by these website terms. Where the two conflict for a specific project, your signed project agreement governs.
Intellectual property
The content on this site – text, layout, and the cost estimator tool – belongs to Second Dwelling Unit Ottawa unless otherwise noted, and may not be copied or republished without permission.
Limitation of liability
To the extent permitted by law, Second Dwelling Unit Ottawa is not liable for decisions made based solely on general information or estimator results from this website, without a formal feasibility review or written quote.
Changes to these terms
We may update these terms from time to time. The "last updated" date above reflects the most recent revision. Continued use of this site after an update means you accept the revised terms.
