Hello Adam,
Great news to hear about your new basement SDU project starting in April
I have done many of these myself and own a few so will try to provide some inside in what I have paid before for a SDU project
- A reasonable timeframe for a basement project is 3 - 4 months but April is will be a very busy time for construction projects and contractors so I would expect a few delays up to 1 month - If you book a company to GC the whole project then it will run smoother then if you are piecing out the work individually
- Your cost should be around $125/ SQFT for this renovation project ( Approx $125,000 plus contingency .... Our costs abit more as we dont keep the furnace and spend around $20,000 just to change the whole mechanical system to hot water radiant heating system ( we do this to get rid of the ducts to eliminate sound and smell between units, get more height in basement, each floor getting there own thermo stat and monthly it costs less to operate), Are you increasing the height of each window in basement? If only changing one of them to larger egress window then will save some funds there
- Contingency in any renovation project is normal as no construction project I have ever seen or been a part of goes under the projected costs. There should not be to many hidden factors when doing a SDU project especially as now your basement is vacant and empty. Things that might come up in a SDU project will mostly be changes the clients wants to add or change which will most likely add to extra charges.....go through the contract with contractor ahead of time to make sure everything that can come up is covered with them.....I always ask my contract to provide a list of what is not covered in the construction as you always get a list of what is covered and dont think about what is not covered in the construction contract
- The costs to borrow will continue to go up based on forcasts so I dont think waiting will help any and a vacant basment doing nothing and not earning income is bigger loss then the extra cost of borrowing
I hope this info helps you and I wish you the best on your project as it sounds exciting :)
If you would like some referrals for some contractors that have done SDU's before then please let me know
Have a blessed weekend
