Maryland's Green Building Laws

October 12, 2010

An increasing number of counties, cities, and towns in Maryland are requiring buildings to be built "green," in accordance with specified sustainable building standards. In addition to those requirements, some jurisdictions are offering tax credits, and other incentives, to encourage green development. Whether prompted by the carrot or the stick, many projects will be going green in the coming years.

At present, Montgomery County requires many newly constructed and extensively modified buildings with more than 10,000 square feet of gross floor area to achieve a "certified" rating under the LEED standards published by the U.S. Green Building Council. Howard County, Baltimore City, and the Cities of Rockville and Gaithersburg also impose green requirements.

The jurisdictions that offer incentives include Baltimore County, Carroll County, and Montgomery County. In Montgomery County, tax credits may be available for buildings that achieve the more stringent LEED gold or platinum levels. Baltimore County and Howard County offer similar credits. A bill pending before the Anne Arundel County Council would provide tax credits for certain residential properties meeting LEED standards.

Additional information on these requirements and programs is included in the attached article, Maryland's Green Building Laws by Linowes partner James Witkin and Kathleen Trinward, published in The Maryland Bar Journal.
