Community Outreach

Serve. Support. Sustain.

These three words summarize CoStar’s commitment to serving the local community, and the mission for our corporate philanthropy program. Together as an organization, we seek to make a difference and bring value to the communities we serve by donating our time and resources to the people, neighborhoods and organizations in greatest need.  Our presence and commitment to expand our reach within the local community and beyond will continue to grow as CoStar grows.

CoStar has partnered with numerous organizations in its effort to support those in need in the Washington, DC area, including working with Hands on Greater DC Cares to clean up the District's Anacostia neighborhood, sponsoring a clothing drive for The Community for Creative Non-Violence and sponsoring the 3rd Annual Semper Fi 5k, a race to raise money and awareness for the Semper Fi fund, a 501 (c)3 nonprofit organization that provides crucial medical and financial assistance to wounded U.S. servicemen and women returning from Afghanistan and Iraq.
