Rehabbing properties in Baltimore City

[Shepard Solomon]

Hello,

I wanted to rehab a property in Baltimore City. I just need to know the rules and regulations dealing with restructuring, renovating, permits, zoning, plans and registrations in the rehab process. I don't want to be fine or have a problem arise that could of been solved earlier. Be free to give all your knowledge please. My property will be near Johns Hopkins if you know any specific criteria for rehabbing in that area, I appreciate it. 

Thanks.
