Doctors Hospital yesterday was told for a second time by the District of Columbia government that it may not move from 1815 I St. NW - a building scheduled for demolition-to a renovated hotel at 1143 New Hampshire Ave. NW.

Carl Wilson, director of the District's State Health Planning and Development Agency, told the hospital he still believes that "under the proposed financing arrangement (the hospital) will not have sufficient control over the project to hold a certificate of need," a document required for any hospital building or expansion.

Jay Wolfgang, the hospital's administrator, said the hospital "plans to vigorously exercise its right to appeal the decision."

The hospital, which must vacate its present building by June 1980 because it is to be torn down to make way for an office-shopping complex, may now appeal Wilson's decision to the city's Board of Appeals and Review, and from there to the D.C. Court of Appeals.

Wolfgang said yesterday the hospital had "not received the reasons for the decision," because the city had not yet delivered the 18-page findings of fact that was to have accompanied the two-page letter from Wilson.

The letter, however, listed four reasons for the rejection, one of which was the hospital's lack of financial control over the project, a reference to the fact that Doctors had arranged to have the new quarters owned and leased back to the hospital by another corporation.

Wilson also said the hospital had not made significant progress on the project since obtaining a certificate of need a year ago, does not have sufficient financing for the project and failed to inform the city properly of the lease-back arrangement.

In October the city rejected Doctors' request for an extension of its one-year certificate of need, citing the lack of financial control.
