Allegheny County, PA Garage & Yard Sales: Frequency Limits (2026)

Allegheny County (a Second Class County under 16 P.S. 3101) has no county-wide ordinance regulating garage sales, yard sales, tag sales, or similar residential personal-property sales. The county's Code of Ordinances does not contain a residential sales chapter, and zoning is reserved to municipalities under the Pennsylvania Municipalities Planning Code (Act 247 of 1968, 53 P.S. 10101 through 11202). Each of the 130 Allegheny County municipalities sets its own rules. The City of Pittsburgh treats an occasional residential yard or garage sale as an accessory use to a residential dwelling and does not require a Permits, Licenses and Inspections (PLI) permit for an isolated sale on private property; there is no enumerated yard-sale license in PLI's Licensing Rules and Regulations, and yard sales do not appear on PLI's commercial license schedule. Many suburban municipalities likewise do not cap frequency by ordinance, while others impose limits (commonly 2 to 4 sales per household per year, 3 consecutive days each) — Mt. Lebanon, Bethel Park, Ross Township, Plum Borough, Monroeville, Penn Hills, McKeesport, and other municipalities each set their own thresholds, and several require the sale items to be the household's own personal property (no resale of merchandise purchased for resale). PA Department of Revenue sales tax rules at 61 Pa. Code Section 32.1 exempt non-recurring isolated sales of personal property by a person not in the business of selling, so an occasional residential garage sale is not subject to the 6 percent PA sales tax or the 1 percent Allegheny County local sales tax (combined 7 percent in Allegheny County). A person who runs frequent or commercial-volume sales would be in the business of selling and must register with PA DOR. Sign placement is regulated separately under each municipality's sign ordinance — Pittsburgh limits temporary residential signs in Title 9 Chapter 919.
