Deeper Dive: 3 Things You Must Know
1. Philadelphia charges the Rental License fee by rental unit
For a duplex in Point Breeze, Newbold, Grays Ferry, West Passyunk, East Passyunk, or another South Philadelphia neighborhood, Philadelphia L&I charges $69 per rented unit.
One Rental License can cover all units in a single building, so this does not necessarily mean you receive a separate license for each apartment. Instead, the City calculates the fee based on the number of rental units covered by that license.
For a standard South Philly duplex:
- Both units rented: $138 per year
- One unit owner-occupied and one unit rented: $69 per year
- Owner-occupied unit: no Rental License fee
- Data Point: Philadelphia L&I currently charges $69 per rented unit, with no fee for owner-occupied units.
- The Action: Check the property in Philadelphia Atlas and L&I records before closing, then verify that the legal number of dwelling units matches the property being advertised.
2. The Rental License is only one cost in your duplex cash-flow calculation
A $69-per-unit licensing fee is relatively straightforward, but it should not be the only City compliance item in your investment analysis.
- Step One: Confirm the legal use of the property through Philadelphia Atlas, zoning records, and L&I. If a property is advertised as a duplex but you cannot document lawful two-unit occupancy, do not underwrite the purchase based on two legal rents until that issue is resolved.
- Step Two: Add the $69-per-rented-unit Rental License expense to lead certification, insurance, maintenance, landlord-paid utilities, and other applicable compliance costs.
For example, if both units require licensing, the base annual Rental License expense is $138 before those other operating costs.
Philadelphia also requires landlords of applicable rental properties built before March 1978 to have the property certified as lead-safe or lead-free. Properties built later must file for an exemption from that certification requirement.
The City does not set one standard market price for hiring the private certified lead professional who performs the testing, so that expense should be quoted separately when you analyze a specific property.
For a house hacker, run a second scenario based on living in one unit and renting the other. Because L&I charges no Rental License fee for the owner-occupied unit, the base annual Rental License fee would be $69 for the one rented unit.
3. A property advertised as a duplex may not be a legal Philadelphia duplex
The hidden risk is assuming that an MLS description, two separate entrances, two kitchens, or two existing tenants proves that a building is legally approved for two dwelling units.
It does not.
Philadelphia requires proof of legal occupancy when a landlord applies to rent out more than one dwelling. Depending on the property's records, that proof may include a Certificate of Occupancy, a qualifying prior Rental License record, or certain zoning documentation.
That distinction matters in South Philadelphia, where older rowhomes may have been altered over time. Before you calculate cash flow based on two rents, verify that the City recognizes the property's lawful occupancy.
Before relying on duplex income, check:
1. The property's use and zoning in Philadelphia Atlas. 2. Whether City records support two lawful dwelling units. 3. Active L&I licenses. 4. Open L&I violations. 5. The property's Rental License status. 6. Applicable lead certification records. 7. Whether the property can obtain a Certificate of Rental Suitability for the tenant.
For a small South Philadelphia investor, confirming legal occupancy should happen before calculating the return based on two rental units.
Local FAQ
How much does a Rental License cost if I live in one unit of my South Philly duplex and rent the other? The base Rental License fee is $69 per year for the rented unit. Philadelphia L&I charges no Rental License fee for an owner-occupied unit.
How much would Rental License fees cost for a South Philadelphia triplex? If all three units are rented, the base annual Rental License fee is $207, calculated as $69 × 3 units. One license can cover all units in the same building, but the fee is calculated per rented unit.
Is a Philadelphia Rental License the same as a Certificate of Rental Suitability? No. A Rental License authorizes the rental operation, while the Certificate of Rental Suitability is a separate tenant-facing compliance document. Philadelphia currently charges $0 for the Certificate of Rental Suitability, and a new certificate is required when renting to a new tenant or renewing an existing tenant's lease.
From My Recent Experience
I recently looked at a South Philadelphia duplex scenario where the advertised two-unit income initially made the property look attractive. Once we looked beyond the rent numbers and checked the City's records, the more important question became whether both units were legally recognized and could be properly licensed—exactly the kind of issue I want a house hacker or small investor to identify before making an offer.
