County Approval of Subdivisions and Land Developments

As of January 2020 there were 28 municipalities in Allegheny County that had not adopted a subdivision and land development ordinance (SALDO). ACED, as the county planning agency, is responsible for reviewing and approving proposed subdivisions and development of land in these municipalities. The Allegheny County Subdivision and Land Development Ordinance (county SALDO) applies. The County’s SALDO establishes the procedures for review and approval of applications; required contents of applications; general design standards; and standards and requirements for public and private improvements. A list of municipalities under the County SALDO is available here. However, the status of a municipality’s SALDO could change at any time at any time. If you have any questions about the list please contact ACED’s Planning Division.


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 Will McLain at 412-350-1361.
