Pennsylvania regulates the security deposit harder than almost anything else in the landlord-tenant relationship, then goes strangely quiet: no entry statute, no late-fee cap, no rent control. The rulebook is the Landlord and Tenant Act of 1951 (68 P.S. § 250.101 and following), and it front-loads its teeth into how you take, hold, and give back the deposit. Start there, because that's where Pennsylvania landlords actually lose money.
Taking the deposit: two months in year one, one month after
During the first year of a lease you may collect up to two months' rent as security (68 P.S. § 250.511a). The day the tenancy enters its second year, the ceiling drops to one month, and if you're holding more than that, the excess belongs back in the tenant's hands. On a $1,500 unit, that's a $3,000 maximum up front, falling to $1,500 at renewal.
Holding the money has its own rules. Deposits over $100 must sit in an escrow account at a bank or institution regulated by federal or Pennsylvania banking authorities, not in your personal checking (68 P.S. § 250.511b). Once a deposit has been held past its second anniversary, it must earn interest, and the tenant gets that interest annually starting in year three, minus a 1% per year administrative fee you're allowed to keep.
One more wrinkle rewards long tenancies: after a tenant has been in possession five years or more, rent increases can no longer trigger a matching increase in the deposit (68 P.S. § 250.511a). Rentari flags these anniversary-driven obligations automatically, which is the sane way to track a rule that changes with each lease year.
Returning it: the 30-day clock and the double-damages trap
You have 30 days from the end of the lease, or from surrender and acceptance of the unit, to hand back the deposit with a written, itemized list of any damages you're charging against it (68 P.S. § 250.512). Miss the deadline and two things happen: you forfeit the right to withhold anything at all, and the tenant can sue for double the amount wrongfully held, plus any accrued interest.
The tenant has one duty that saves landlords constantly: they must give you their new address in writing when they leave. No written forwarding address, no double-damages exposure. Don't lean on that escape hatch, though; courts read the 30-day rule strictly, and "the check was almost ready" is not a defense.
Deduct only real losses: unpaid rent, damage beyond ordinary wear and tear, other lease breaches you can document. Photos at move-in and move-out win these cases. Neighboring New Jersey runs the same general idea on different math and stricter interest rules, so don't copy paperwork across the river.
Rent, late fees, and raising either one
Pennsylvania has no rent control, statewide or local, and no statute caps late fees or imposes a grace period. Your lease does that work. Courts will still refuse to enforce a late fee that looks like a penalty rather than a reasonable estimate of what the delay costs you, so keep the number modest and stated plainly in the lease.
Raising rent on a month-to-month tenancy takes reasonable advance notice statewide, but Philadelphia wrote its own rule: inside the city, a rent increase requires 60 days' written notice for tenancies of a year or more, 30 days for shorter ones, and the notice must state the increase, the new amount, and the effective date (Phila. Code § 9-804). Get the mechanics wrong and the increase is unenforceable before the city's Fair Housing Commission.
Entry: the statute Pennsylvania never wrote
Pennsylvania is one of the minority of states with no statute governing landlord entry. No 24-hour rule, no defined "reasonable times." The lease controls, and underneath it sits the tenant's common-law right to quiet enjoyment, which courts take seriously.
Write an entry clause into every lease (24 hours' notice, reasonable hours, emergencies excepted) and then follow it. Without one, you're arguing about what "reasonable" means in front of a district judge who may not see it your way.
The notice-to-quit ladder, and the waiver hiding in your lease
Before filing for eviction, 68 P.S. § 250.501 requires a written notice to quit: 10 days for nonpayment of rent, 15 days for other breaches or end of term on leases of a year or less (month-to-month included), and 30 days on leases longer than a year.
Here's the quirk that surprises out-of-state owners: the notice to quit can be shortened or waived entirely by the lease, and most Pennsylvania form leases do exactly that. If your signed lease contains a valid waiver clause, you can file directly in Magisterial District Court. If it doesn't, the statutory notice applies in full, so read the actual document before you act.
Two hard limits survive no matter what the lease says. Self-help is out: no lockouts, no utility shutoffs, no hauling possessions to the curb without a court order and an executed order for possession. And belongings left behind follow 68 P.S. § 250.505a: written notice to the tenant, 10 days from the postmark to claim (or request up to 30 days of storage), with treble damages plus attorney fees if you skip the process. Pennsylvania-specific notice forms live in our forms library.
Habitability: the rule Pennsylvania's courts wrote instead
No habitability statute exists here either; the Pennsylvania Supreme Court created the implied warranty of habitability in Pugh v. Holmes, 486 Pa. 272 (1979), and it can't be waived by lease. A defect that makes the home unfit to live in (no heat, no water, serious leaks, unsafe wiring) breaches the warranty.
The remedies have real force: tenants may withhold rent while the breach continues, or repair and deduct reasonable costs after giving you notice and a fair chance to fix it. Philadelphia stacks paperwork on top: the city requires a rental license and a Certificate of Rental Suitability at lease signing, plus lead-safe certification for most pre-1978 units, and an unlicensed landlord can't even sue for rent. Wherever the property sits, pre-1978 housing also carries the federal lead-based paint disclosure and pamphlet.
What changed in 2024-2026 (statewide: very little)
Harrisburg passed no significant amendment to the Landlord and Tenant Act in the 2024, 2025, or 2026 sessions; the last structural change of consequence was the abandoned-property procedure added as 68 P.S. § 250.505a by Act 129 of 2012. Eviction-record sealing and statewide notice-reform bills have been introduced repeatedly and gone nowhere. That quiet is itself worth knowing: your 1951-vintage obligations are stable, and the short-form numbers stay current on our Pennsylvania quick-reference page.
The movement is municipal. Philadelphia made its Eviction Diversion Program permanent: for the filings it covers, you must apply to the program and participate in good faith for at least 30 days before filing in court, and skipping it is grounds for dismissal (Phila. Code § 9-811). The city also enforces good-cause requirements for many non-renewals alongside its 60-day rent-increase notice. Pittsburgh keeps pushing rental registration through the courts. If you own in New York as well, the contrast is sharp: New York rewrote its state law in 2019; Pennsylvania mostly lets its cities do the writing.
Pennsylvania landlord FAQ
Can I really charge a two-month security deposit?
Yes, but only during the first year of the tenancy (68 P.S. § 250.511a). From year two onward the cap is one month's rent, and the overage must be returned. After five years of possession, rent increases can't pull the deposit up with them.
When do I owe a tenant interest on the deposit?
Once the deposit has been held more than two years. From the start of year three you pay the tenant the interest annually, keeping 1% per year as your administrative fee (68 P.S. § 250.511b). Deposits of $100 or less escape the escrow rules entirely.
Do I always have to serve a notice to quit before evicting?
No. The 10, 15, and 30 day notices in 68 P.S. § 250.501 apply only if your lease didn't waive them, and most written Pennsylvania leases do. Verify the waiver clause exists in the signed copy before filing without notice.
Is there anything special about evicting in Philadelphia?
Yes. For covered cases you must enroll in the city's Eviction Diversion Program and participate in good faith for 30 days before filing (Phila. Code § 9-811), and the city requires a current rental license to pursue rent claims at all. Budget the extra month into any Philadelphia timeline.
How much notice to raise rent on a month-to-month tenant?
Statewide, no fixed number; give reasonable written notice, commonly a full rental period. In Philadelphia it's codified: 60 days for tenancies of a year or more, 30 days for shorter ones (Phila. Code § 9-804). No Pennsylvania jurisdiction caps the amount.
