In May 2012, Maryland enacted legislation stating that any calculation of "impervious surface" required by state or local authorities as part of a permit or variance relating to zoning, construction, or stormwater may only include the foundation or base supporting the solar panel. The law generally applies statewide, including charter counties and Baltimore City. It does not however apply in a defined "critical area", including the Chesapeake Bay Critical Area and the Coastal Bays Critical Area. The term "solar panel" is not specifically defined, but presumably would include both solar photovoltaic (PV) and solar thermal panels.

Western Riverside Council of Governments (WRCOG) is offering business owners in WRCOG participating jurisdictions an opportunity to finance energy and water efficiency projects for their commercial properties. The HERO Commercial Program is a Property Assessed Clean Energy (PACE) financing program. PACE programs allow businesses to finance energy improvements, and to repay the financing through special assessments on their property taxes. 

Note:  In 2010, the Federal Housing Finance Agency (FHFA), which has authority over mortgage underwriters Fannie Mae and Freddie Mac, directed these enterprises against purchasing mortgages of homes with a PACE lien due to its senior status above a mortgage. Most residential PACE activity subsided following this directive; however, some residential PACE programs are now operating with loan loss reserve funds, appropriate disclosures, or other protections meant to address FHFA's concerns. Commercial PACE programs were not directly affected by FHFA’s actions, as Fannie Mae and Freddie Mac do not underwrite commercial mortgages.

In March 2012, West Virginia enacted legislation (H.B. 2740) that restricts housing associations from prohibiting solar energy systems on homes. Any governing document executed or recorded after June 8, 2012, that effectively prohibits or restricts the installation or use of a solar energy system is void and unenforceable. However, housing association members may vote to establish or remove a restriction that prohibits or restricts the installation or use of a solar energy system.

A solar energy system is defined as "a system affixed to a building or buildings that uses solar devices, which are thermally isolated from living space or any
