The District of Columbia Sustainable Energy Utility (DCSEU) currently offers incentives on air sealing and insulation as part of Home Performance with ENERGY STAR. The DCSEU provides up to $450 in incentives for homeowners who successfully complete qualifying home energy upgrades. Qualifying upgrades require working with a participating contractor, completing a minimum of $600 work of approved improvements.

It does not however apply in a defined "critical area", including the Chesapeake Bay Critical Area and the Coastal Bays Critical Area.

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. Visit PACENation for more information about PACE financing
