I believe it’s like 30 years to remain compliant for tax credits.

ADA may also require access changes for the commercial space. 

I would look at getting a bid for a smaller deck or better yet, replacing with a concrete patio.

@Suvarna Joshi I work for a home builder in Tampa Fl we borate treat all of the wood we use in direct contact with concrete on our home.

Yes, you had to make sure you’re legally compliant, but it is something with an average individual can do.

You said counting every single doorknob would annoy them, but do you at least get it itemized into how much for electrical, plumbing, framing, drywall, floors, foundation, etc.I still think I'm going to get a quantity takeoff at least when I'm just starting out with a new GC even just for the sake of letting them know that I'm not completely ignorant on the topic (and thus easy for them to lie to).I can tell them exactly how many CY of concrete will be needed for the foundation and footings and I know that it costs about $130/CY.

We’re also capable of performing concrete and asphalt work in-house.

Is it concrete?

There was no tall concrete wall to block the noise, only the heavy vegetation naturally growing there. 

If you are talking about the concrete curing process, it's around 30 days for it to fully cure. 2) You can type in the city name and zoning to look it up.
