Hello! I'm a carpenter and my dad and I are looking to build a garden suite in our backyard in Oakville. I haven't been able to find answers for a few different things but I think I'm in the right place to get some lol. 1. Can I realistically design the entire thing myself or get freelancer Architects to save some money I'm getting quotes from Architects at about $7-$10,000 2. Are we legally allowed to contract and build it ourselves without a Tarion license? My dad is the homeowner. Are we allowed to do the plumbing and electrical as long as we pass Inspections? 3. If we can is it realistic to build it for $125 per sqft, I'm a good carpenter and have been working full-time for 4.5 years.
