Fire Suppression/Sprinkler Installation

[J Frank Cole]

Hello,

I have a question regarding fire suppression and fire sprinklers. I'm not sure if this is the right forum for this, but here goes.  My wife and I are in the process of creating a residential assisted living facility. As a matter of course, we have to bring the building up to code which includes ADA compliance (grab bars and roll in showers) and fire suppression/detection (fire sprinklers, alarms and lights, etc.). The ADA stuff is relatively straight forward and will be fairly cheap. The sprinklers are new to us. Anyone out there have any experience with this, even commercially? The company's I've talked to, state that the attic as well as the living space must be protected because it's a wood structure. Because I don't have plans for the house yet I only got a very rough price at $350/square foot. Is this typical, or higher than it needs to be? Keep in mind that $85,000 would be the price of the sprinklers alone. I would still need to get a new, separate underground line installed with two individual water lines, and fire alarms and emergency lights installed. I'm very realistic when it comes to renovation cost, I was a contractor before I got into real estate, but have no experience with any of this stuff.

Any help would be greatly appreciated.

Thank you.
