Condominium developers now are required to have a broker's license to sell a condominium development of 10 or more units in the District.

Mark P. Griffin, a member of the D.C. Real Estate Commission, said a recent opinion from Louis P. Robbins, acting corporation counsel, holds that the licensing provision includes any person who owns and subdivides property into 10 or more lots-and that applies to condominium conversions or new condominiums.

"Basically, what Robbins has said is that creation of a condominium regime containing 10 or more units falls within the purview of the licensing law so as to require the developer, as a condition precedent to sell units himself, to have a broker's license or employ a license broker," Griffin said.

Griffin added that the D.C. Real Estate Commission intends to enforce this provision of the Real Estate and Business Brokers Act of 1937, which differs from regulations in Maryland and Virginia, where no similar stipulation exists regarding 10 lots or more.

The Corporation counsel's opinion was sought in the District, Griffin said, because of several complaints about a condominium developer's sales staff.

Anyone selling his own property or subdivisions of fewer than 10 lots is not affected by the D.C. ruling on the licensing act provision.
