Maryland - sprinkler system requires?

[Chris Seveney]

I am looking at a property that is a six unit (actually 3 separate buildings on 1 property but legal). It's two single units and a main house with 4 units. It's in Maryland and I am wondering if I will be required to put sprinkler systems in the buildings or would be required too if I upgraded the homes? Any insight would be helpful - and yes I am gonna call and visit the building and zoning department as well but also like to get actual perspective from investors on what they have had to do Thanks
