Are there special laws in Maryland concerning building or adding on to existing buildings?
The State of Maryland has adopted the series of model codes published by the International Code Council, and these have been endorsed, with some modifications, by most local jurisdictions. The Office of the State Fire Marshal uses codes and standards published by the National Fire Protection Association. These two code families often cover the same topics, but in slightly different ways, and sometimes there are conflicts. Architects must design their buildings to meet the most stringent of the codes and local ordinances.
