Pennsylvania Nonconforming Use Letter: Protect Your Property Rights

If you own property in Pennsylvania that was legally established before a zoning ordinance changed, you likely have a constitutionally protected right to continue that use. This is called a lawful nonconforming use, and Pennsylvania courts have consistently defended it as a vested property right. When a township, borough, or city zoning officer threatens enforcement, fines, or denial of a permit, a properly drafted nonconforming use letter can stop the action before it escalates to a costly hearing before the Zoning Hearing Board. Pennsylvania's Municipalities Planning Code (MPC) and decades of appellate case law set strict limits on what municipalities can do to terminate or restrict these uses. A timely, well-cited demand letter protects your investment and preserves your appeal rights.

Pennsylvania protects nonconforming uses under the Municipalities Planning Code, 53 P.S. §§ 10101 et seq., and through robust case law including Hanna v. Board of Adjustment, 408 Pa. 306 (1962), and PA Northwestern Distributors, Inc. v. Zoning Hearing Board, 526 Pa. 186 (1991). A nonconforming use is any use, structure, or lot that lawfully existed before the current zoning ordinance was enacted but no longer complies with it. Pennsylvania courts treat the right to continue such a use as a vested property right protected by the Pennsylvania Constitution's prohibition on taking property without just compensation. Municipalities cannot simply zone out an existing use through amortization without compensation — the Supreme Court in PA Northwestern struck this practice down. Owners are entitled to continue, repair, and even reasonably expand a nonconforming use to meet natural business growth, under the doctrine established in Silver v. Zoning Board of Adjustment, 435 Pa. 99 (1969). However, the use can be lost through abandonment, which under 53 P.S. § 10613 generally requires both an intent to abandon and a discontinuance — often presumed after one year of nonuse, though the period varies by local ordinance. A change to a different nonconforming use, or expansion beyond what is reasonable, may also forfeit protection. Property owners challenging a zoning officer's determination must file an appeal with the Zoning Hearing Board within 30 days under 53 P.S. § 10914.1. Failure to appeal in time generally waives the right to contest the decision. A nonconforming use letter establishes the factual and legal record early, citing the date of original use, prior permits, tax records, and continuity evidence necessary to defeat any abandonment or illegality claims.

A Pennsylvania nonconforming use demand letter works because it forces the municipality to confront the legal weakness of its enforcement position before incurring litigation costs. The letter should be addressed to the zoning officer, township solicitor, and board of supervisors or council, and it should accomplish four things. First, it documents the date the use was established and proves continuity through tax records, utility bills, business licenses, photographs, affidavits, or prior permits. Second, it cites the controlling MPC provisions and Pennsylvania Supreme Court cases — particularly PA Northwestern, Hanna, and Silver — to establish that the use is constitutionally protected. Third, it disputes any factual claim of abandonment, change of use, or unlawful expansion, and demands the municipality identify the specific ordinance section and evidence supporting enforcement. Fourth, it preserves the 30-day appeal deadline by signaling that an appeal to the Zoning Hearing Board will be filed if the violation notice is not withdrawn. Municipal solicitors routinely advise their clients to back down when faced with a well-documented letter because losing a nonconforming use case at the Commonwealth Court level can expose the township to attorney fee awards under 42 Pa.C.S. § 2503 for bad faith conduct. The letter also creates a paper record useful in any later inverse condemnation or 42 U.S.C. § 1983 federal civil rights claim if the municipality persists.

Appeals from a zoning officer's determination must be filed with the Zoning Hearing Board within 30 days under 53 P.S. § 10914.1. Filing fees vary by municipality but typically range from $500 to $2,500, plus stenographer costs. Further appeals go to the Court of Common Pleas under 53 P.S. § 11001-A, then to the Commonwealth Court. Pennsylvania's small claims (Magisterial District Court) limit is $12,000, but zoning matters generally cannot be filed there — they must proceed through the Zoning Hearing Board first under the doctrine of exhaustion of administrative remedies. Owners should preserve all evidence of continuous use and avoid any gap that could be argued as abandonment under local ordinance, which varies by jurisdiction.
