Frequently Asked Questions About Multi-Unit & ARU Conversions

What is the typical cost for a legal basement apartment conversion in Toronto?+
The cost for a legal basement apartment or ARU conversion in the GTA typically ranges from $80,000 to $250,000. This depends heavily on the existing condition of your basement, the scope of work, required upgrades for compliance (e.g., egress windows, soundproofing), and chosen finishes. Our 1-hour photo-to-quote system provides an initial estimate quickly.
How long does a multi-unit conversion project usually take?+
A typical multi-unit or ARU conversion project, from permit acquisition to final inspection, usually takes between 8 to 16 weeks. This timeline can vary based on the project's complexity, permit approval times, and material availability.
Do I need permits for a basement apartment conversion?+
Yes, absolutely. Legal basement apartment and ARU conversions require various permits, including building permits, electrical permits (ESA), and plumbing permits. We handle the entire permit application process for you, ensuring full compliance with local bylaws, including the Toronto Multiplex Bylaw 2023.
What's included in a RenoHouse turnkey ARU conversion?+
Our turnkey ARU conversion service includes everything from initial design and architectural drawings to permit acquisition, demolition, framing, electrical, plumbing, HVAC, insulation, drywall, flooring, kitchen and bathroom installation, egress window installation, soundproofing, and final finishing. We manage the entire project from start to finish.
Do you offer a warranty on your conversion services?+
Yes, we stand behind the quality of our work. RenoHouse offers a comprehensive warranty on all workmanship and installations for our multi-unit and ARU conversion projects. Specific warranty details will be provided in your project contract.
Are your trades licensed and insured for ARU conversions?+

We are also WSIB (Workplace Safety and Insurance Board) cleared, ensuring a safe and professional work environment.
How quickly can I get a quote for my ARU conversion project?+
Thanks to our innovative photo-to-quote system using Telegram and Gemini Vision, you can receive an initial, transparent quote for your multi-unit conversion project within just 1 hour of submitting your photos. This is significantly faster than traditional methods.

Can RenoHouse help with just egress windows or soundproofing for my basement?+
While we specialize in full turnkey conversions, we do offer specialized services for critical components of ARU compliance. This includes installing legal egress windows, soundproofing solutions, and creating second egress points. Contact us with your specific needs.
Is the initial consultation or quote free?+
Our initial 1-hour photo-to-quote service is completely free. This provides you with a transparent estimate based on your submitted photos. A detailed on-site assessment, which may be required for complex projects, will be scheduled after the initial quote and discussion.
