​Construction Cost Estimates in Chicago

[Frank S.]

Hi  BPs, 

I'm looking for feedback, please. This is for a property I saw a few weeks ago, I'm trying to check my guesstimates.

What would the approximate cost be to replace an entire flat roof in Chicago? Assume a typical Chicago lot. Include permit and proffessional fees.

I assumed $18,000 including some of the plywood. Perhaps up to $25,000 with pareapet brick reconstruction.

What would the approximate cost be to replace a back porch for a two flat in Chicago? Include permit and proffessional fees.

Thanks,

It depends how many layers on the tear off but it looks like you've got quite a few there. Regardless no way you pay that much unless you hire a union company like Allendorfer. 

I've done multiple tear offs and you're budget (assuming a standard building on a standard 25x125) is in the $8000 to $12000 range depending upon the extent of plywood replacement and R value on the insulation you put in. I paid $8k last year on a tear off in Bucktown. 

I suggest putting in at least 4 inches to cap your building and improve energy consumption, At the time of the tear off coordinate renting a blown insulation machine too and you can add insulation from the roof into the attic/crawl space above the ceiling level to avoid interior repairs. It works wonders especially if you're paying the heating bills. Even if you're not get copies of how low your heat bills are and use that in your marketing when renting your units. 

Good lucK!
