Pennsylvania subletting rules for landlords: the Act binds sublessees to the lease and leaves consent to your lease

What does section 105 do?

It binds the sublessee: "Any person who is a sublessee shall be subject to the provisions of the lease between the lessor and the lessee." That is a useful rule for a landlord. A subtenant cannot claim better terms than the head lease gives, and the rules in your lease about use, noise, pets and damage reach the subtenant.

What does section 203 require?

For leases of more than three years, no lease can be assigned, granted or surrendered except in writing signed by the party assigning, granting or surrendering it, or the party's agent. Transfers by operation of law are excepted. Most apartment leases are shorter than three years, so this section is a niche rule for long leases. Section 202 adds that such a lease must be in writing and signed by the parties.

Example a made-up landlord in Pittsburgh has a five-year ground-floor retail-and-apartment lease. A tenant wants to assign it. Section 203 requires a signed writing for the assignment, and the landlord's lease decides whether consent is needed.

What does the Act not say?

The sections I read do not say whether a tenant needs the landlord's consent to sublet, how fast a landlord must answer, whether a refusal must be reasonable, or whether a fee may be charged. For ordinary residential leases that leaves the lease itself as the main source of the rule. A short, clear clause answers all four questions for your tenants and for a judge.

What should the lease clause cover?

1. Whether subletting or assignment needs your written consent.
2. What the tenant must submit: the proposed occupant's name, dates and an application.
3. How long you will take to answer.
4. Whether the original tenant remains responsible for rent and damage.
5. That the subtenant is bound by the lease, mirroring section 105.

Writing the rules your lease must supply

Because the Act is silent on consent, your lease is the rulebook, and a short one beats a long one. Say that subletting and assignment need your written consent, that requests must come with the proposed occupant's details, and that you will answer within a stated number of days. Say that a consented subtenant is bound by the lease, which mirrors section 105, and that the original tenant remains responsible for rent and damage. For any lease running more than three years, add a line that an assignment must be in a signed writing, which mirrors section 203. Review the clause whenever you renew, and keep each tenant's signed version.

Pennsylvania landlords also deal with local rules and with subsidy programs that have their own sublet restrictions, so check those where they apply. Keep a note of which of your units are covered by such programs, and keep that note with the lease.

How DoorKeeping fits in Pennsylvania

DoorKeeping keeps a Pennsylvania tenant's sublet or assignment request in the unit's message thread with the date it arrived, the proposed occupant's details and your reply. The clause you wrote and the request you received sit in the same thread, so the answer to the missing questions is on the record. This is general information, not legal advice. Check the current statute and your lease before you act.
