County Approval of Subdivisions and Land Developments

As of May 2017, 27 municipalities in Allegheny County have not adopted a subdivision and land development ordinance (SALDO). In these municipalities, the standards and requirements in the Allegheny County Subdivision and Land Development Ordinance apply. The county planning agency, which is ACED, is the authority for review and approval of subdivisions and land developments. ACED’s Planning Division is responsible for administering the County SALDO on behalf of the 27 municipalities. Click here for a list of the municipalities where the County’s SALDO governs.


If your municipality hasn’t adopted a subdivision and land development ordinance and you would like more information about the County SALDO, Planning Division staff will be happy to meet with you. Please call Kay Pierce at 412-350-1030, or Andrew Hartwell at 412-350-1360.
