Marie Nahikian, a member of the D.C. Rental Accommodations Commission and an activist in housing and neighborhood conservation, announced her candidacy Monday for an at-large seat on the City Council.

Speaking on the steps of the District Building, Nahikian said she would enter the Democratic Primary.

A resident of the Adams-Morgan neighborhood for more than a decade, Nahikian recently resigned as executive director of the D.C. chapter of Common Cause, the citizen lobby.

The founder and first executive director of the Adams-Morgan Organization, she is serving her second term on the Rental Accomodations Commission, which oversees administration of the city's rent control law.

She was active in pushing for council enactment of the recently passed antispeculation-tax bill and renewed rent control legislation.

In 1975, she convened a national meeting of neighborhood representatives in Washington that led to formation of the National Association of Neighborhoods.

She said her candidacy would "represent communication and a bridge" among diverse groups in the city, leading to solutions to youth employment, housing and decisions on who will be able to live in the District in the future.

Her campaign cochairpersons are Fannie Hill and George Starke. Those present at her announcement included people active in the rival mayoral candidacies of Sterling Tucker and Marion Barry.
