Pennsylvania's two big preservation markets took opposite approaches to vacancy. Philadelphia built one of the country's most complete licensing regimes — annual licenses, size-tiered bonds, rodent inspections. Pittsburgh built none, and enforces through condemnation instead. An owner or servicer working both cities is really working two different regulatory systems, and this page lays out each from the cities' own documents.
Philadelphia: A License, Not Just a Registration
Philadelphia's Department of Licenses and Inspections issues three vacant property licenses — residential, commercial, and pier — under Code Chapter 9-3900. The official application defines the trigger: a structure that lacks the habitual presence of human beings who have a legal right to be on the premises, or where substantially all lawful business operations or residential occupancy ceased within the past three months. A lot qualifies after three months without productive activity. Residential structures under active renovation are exempt.
Both the residential and commercial licenses cost $202 per year, including a $20 non-refundable application fee, and renew annually — with a late charge of 1.5% of the fee per month once renewal is more than 60 days overdue. The owner must be current on all city taxes and hold a Commercial Activity License. Vacant lots require an annual rodent inspection by a Pennsylvania-licensed pest control company. Licenses do not transfer: a new owner has 10 business days from the transfer to obtain their own.
The Commercial Bond Schedule
| Commercial structure size | Required bond |
|---|---|
| Under 50,000 sq ft | $50,000 |
| 50,000–200,000 sq ft | $100,000 |
| Over 200,000 sq ft | $500,000 |
The bond is what separates Philadelphia from fee-only programs: on a large vacant commercial building, the carrying cost of vacancy includes securing capital, not just an annual license. Vacant piers carry their own requirements — certified onshore barriers and danger signage on all sides.
On enforcement, the city's pages say only that unlicensed vacant properties "may be subject to fines and violations." One number is verifiable at the source: the city's certified windows-and-doors ordinance (Bill No. 140856) sets a $300 code violation notice for breach of the vacant-premises standards it renumbered into the property maintenance code, classified as a Class II offense. Larger per-opening, per-day figures circulate in secondary coverage of Philadelphia's famous "windows and doors" program; treat any figure you cannot trace to the current code text with caution.
Pittsburgh: No Registry, Different Leverage
Pittsburgh's Permits, Licenses and Inspections registration page lists exactly two registration programs — rental housing (launched December 2024) and child-occupied facilities. There is no vacant or foreclosed property registration. Vacancy is handled through enforcement: condemnation of unsafe structures, facade inspections, clean-and-lien abatement, and the property maintenance code's provisions for closing vacant structures. Owners of condemned buildings must repair or obtain demolition permits.
The practical difference: Philadelphia's costs are predictable and annual; Pittsburgh's arrive as condemnation orders, abatement liens, and court dates when a property deteriorates enough to draw attention. A maintained, secured, documented building generates neither.
Working Both Cities
- Calendar Philadelphia license renewals annually and the 10-business-day clock on every acquisition or disposition
- Budget the bond, not just the fee, on vacant Philadelphia commercial assets
- Book the rodent inspection early on Philadelphia lots — it requires a licensed third party
- In Pittsburgh, treat securing and exterior maintenance as the compliance program, because enforcement is condition-triggered
- Keep dated photo documentation in both cities; it answers an L&I inspector and a condemnation hearing equally well

Frequently Asked Questions
1When does a Philadelphia property need a vacant property license?
Per the city's L&I license application, a structure needs one when it lacks the habitual presence of people with a legal right to be there, or when substantially all lawful occupancy or operations ceased within the past three months. A lot qualifies with no productive activity for at least three months. Residential properties under active renovation are exempt.
2How much does the Philadelphia vacant property license cost?
$202 per year for both the residential and commercial licenses, including a $20 non-refundable application fee, renewed annually. Renewing more than 60 days late adds 1.5% of the fee per month.
3Does Philadelphia require a bond on vacant commercial buildings?
Yes. Per the city's license pages, vacant commercial structures carry a bond requirement tied to size: $50,000 under 50,000 square feet, $100,000 from 50,000 to 200,000 square feet, and $500,000 above 200,000 square feet.
4Does Pittsburgh have a vacant property registration program?
No. Pittsburgh's Permits, Licenses and Inspections department lists no vacant or foreclosed property registration — its registration programs cover rental housing and child-occupied facilities. Vacancy is policed instead through condemned-building enforcement and the property maintenance code, including authority to close vacant structures.
5What happens when a Philadelphia property changes hands?
Licenses are not transferable. A new owner must obtain a new vacant property license within 10 business days of the ownership transfer, and information changes must be reported within the same window.
