Unlicensed Landlord in Philadelphia: Your Rights Under § 9-3902

If the rental license on your building is expired or missing, Philadelphia law limits what your landlord can collect — and how they can evict. Here's what the law says, and the mistake not to make.

Published August 1, 2026

What the law says

Philadelphia requires every residential rental property to hold a valid, active rental license issued by Licenses & Inspections. Two provisions of the Philadelphia Code give that requirement real force:

• § 9-3902(1)(a) — a landlord may not collect rent on a property that requires a rental license unless a valid license is currently in force.
• § 9-3901(4)(e) — an owner who lets the license lapse cannot collect rent or evict for nonpayment during the period of non-compliance.

The license isn't a formality — it's the legal basis for the rent relationship. When it lapses, the landlord's entitlement to collect lapses with it, for as long as the non-compliance lasts.

The courts have backed this up

In Frempong v. Richardson, 209 A.3d 1001 (Pa. Super. 2019), the Pennsylvania Superior Court confirmed that tenants may recover rent paid during periods when the landlord was unlicensed. That means an expired license isn't only a shield against collection going forward — money already paid during the unlicensed period can be on the table. How that applies to your situation is exactly the kind of question a housing attorney should answer.

The mistake not to make

The legal path runs through documentation and, where needed, the courts:

1. Document the problem. Photograph or video conditions. Note dates.
2. Notify the landlord in writing. Certified mail is recommended. Describe the problem and request repair within a reasonable time (typically 30 days for non-emergencies).
3. File a 311 complaint. Dial 3-1-1 or file at phila.gov/311. This creates a public record tied to the address and can trigger an L&I inspection.
4. If the landlord doesn't repair: a tenant can petition the Court of Common Pleas to pay rent into a court-supervised escrow account instead of to the landlord. The court holds the funds until repairs are made.
5. Get legal guidance before withholding anything. Community Legal Services: 215-981-3700.

When the landlord also lacks a valid rental license, § 9-3902 gives you additional grounds — their right to collect is already legally impaired — but the sequencing and strategy belong in a lawyer's hands.

Retaliation is illegal — and presumed

Under the Pennsylvania Landlord-Tenant Act § 5720, a landlord may not retaliate against a tenant for exercising legal rights — reporting code violations to L&I, filing with the Fair Housing Commission, joining or organizing a tenants' union, or withholding rent through the legal escrow process.

If the landlord raises rent, cuts services, threatens eviction, or files for eviction within six months of you exercising one of those rights, the law presumes retaliation — the burden shifts to the landlord to prove a legitimate, non-retaliatory reason. Document everything: dates, letters, texts, case numbers.
