That does institutional government building mean

Hi Isabella, Check with the zoning, planning and building department in city or county where the property is located. Determine if the property is in their jurisdiction. Ask them about past, present and any possible future uses of the property. Is it currently occupied? How old is the building? Is it a modern building? Does it still have any functional life left? If it is old, can it be revitalized? How much will it cost? What is the property worth?
Consider consulting with: architects, engineers, contractors, brokers, attorneys, etc.

Check with the local planning department, but usually it means the building that has been used by the government. So more than likely your buyer would have get the building re-zoned.
