The Obama administration is clamping down on excessive pay at public housing authorities, setting caps that extend and expand limits imposed by Congress. After conducting a national compensation survey, the U.S. Department of Housing and Urban Development plans to set a maximum salary ceiling of $155,000 for public housing agency officials, according to two senior administration officials. The cap applies to the portion of executive salary paid with federal money. Agencies can still supplement a top officials pay with state or local government money. While the top limit planned by the Obama administration would be $155,000 for agencies managing more than 1,250 public housing units, HUD would set lower limits for smaller public housing agencies. Housing authorities with between 250 and 1,250 units could pay a maximum of $125,926, and agencies handling fewer than 250 units could pay no more than $88,349.
