The owner of an Arlington apartment complex who was charged by the Justice Department with discriminating against blacks has agreed to take corrective measures to assure fair housing practices, according to a department spokeswoman.

House Realty and Development Co. and its owner, Eugene R. House, were accused of following "a pattern and practice of making dwellings unavailable to black persons" that included falsely telling blacks that apartments were not available for rent or inspection, according to a Justice Department release.

Helen Slone, manager of the Glenayr Apartments, a 154-unit complex in Ballston where the alleged discrimination occurred, also was named in the suit, which was filed Monday in U.S. District Court in Alexandria.

Slone declined to comment yesterday; attempts to reach House were unsuccessful.

The suit was filed after random discrimination tests were conducted at the apartment complex by the Regional Fair Housing Consortium, according to Justice Department spokeswoman Deborah Burstion-Wade. The consortium comprises housing and human rights groups throughout the metropolitan area.

As part of the testing, blacks and whites visited the apartments and reported back to the consortium on how they were treated and whether they were shown or offered apartments to rent.

Based on the tests, Justice Department officials found that Glenayr had discriminated against black applicants "because of race or color," according to the department release.

While the defendants "did not admit to violating the 1968 Fair Housing Act," Burstion-Wade said they did enter into a consent order with the Justice Department that requires House's firm to cease any discriminatory practices; to keep logs on all rental applicants, including their names, addresses, races and reasons for rejection; to advertise fair housing practices, and to instruct current and future employes on fair housing policies.

Federal officials will review the logs every three months for three years, she said.
