Second story extension

We're thinking of putting an addition on our home (detached, 2 story in Toronto, Canada) and are wondering what a reasonable budget would be. Second story only, above existing first floor with full foundation -approx 120 sq ft. We are also thinking about extending the addition beyond the existing first floor using an overhang supported by columns, creating a covered deck underneath. Probably an additional 200 sq ft.

Thoughts and/or pricing on this type of addition?

Thanks

After reading through some other posts I realized more info would be needed.

Large lot with lots of access. Reno would include reorganizing our second floor to allow for a fourth bedroom . This would include moving plumbing, additional windows, and electrical.

Just need a ball park as all contractors want to know your budget when starting out discussions, but without any sense of what the work would be worth we cannot set a budget.

Thanks!

There are so many things to take into account.

Height restrictions. What are you building over. All your 1st floor ceiling must be opened up to install proper floor joist for

second floor, heating ducts for extended part.

Full footings and concrete piers for extended part. Your probably looking at a minimum

of $ 80K

Your first step is to take your property survey to your local zoning-building department at city hall. They can tell you what the regulations are for your area of town or city.

Cost to build a home addition vary from $250 per square foot on the cheapest end to $500 / sq. ft. or even more for custom top notch work. Accurate estimated can be provided only after analyzing architectural drawings with all technical details, calculating number of man-hours for completing the project and determining the total expenses for materials, fixtures and finishing products.

Committee of Adjustment will cost $ 1,500 if you are closer than 6 ft. to the property side line and apply for a variance.
