Also, seeing that this building has no sprinkler system is a big setback. If you are inside the city limits, then you can either kiss this building goodbye, or devote a lot of money to get a fire suppression system going. Not to put a big dent in your plans, but with the budget that you have, if your inside the city limits, then it might be very hard to get this project off the ground.
Don't let me get you down though- check with your local fire chief(before you approach you fire marshall). Talk to the chief first. From my experience, this works better than going stright to the fire marshall.
