County manager plan of government; affordable dwelling unit ordinance.

County manager plan of government; affordable dwelling unit ordinance. Increases local authority over affordable housing for counties that have adopted the county manager plan of government (Arlington County) by (i) potentially increasing the cash contribution to the county's affordable housing fund by developers in lieu of providing affordable dwelling units and (ii) providing that applications for a special exception approval for a change of use of an existing building from commercial to residential may be subject to an affordable housing requirement. The bill directs the governing body of such counties to appoint an advisory board to advise the governing body regarding the appropriate provisions of an ordinance to amend the cash contribution amounts to such county's affordable housing fund. Certain provisions of the bill do not become effective unless reenacted by the 2027 Session of the General Assembly.
