For many renters in Pittsburgh, living with roommates is a practical way to afford a larger apartment or split housing costs. However, the way a lease is structured determines how financial responsibility is shared. When multiple roommates sign one lease, they typically enter into a joint lease with “joint and several liability.” Understanding what this means and how to protect yourself can prevent disputes and financial surprises.
Joint and Several Liability Explained
Most Pittsburgh leases with multiple tenants use joint and several liability. This legal principle means that each tenant is responsible for the full rent amount, not just their individual share. A Pennsylvania Superior Court case confirmed that co-signers are “jointly and severally liable” for rental payments, meaning the landlord can pursue any one tenant for the entire amount owed.
In practice, this means:
- You are responsible for your roommate’s unpaid rent. If your roommate does not pay their share, the landlord can demand the full rent from you.
- The landlord can pursue any tenant individually. If one roommate has more assets or income, the landlord may target that person for collection.
- Eviction affects everyone. If one roommate violates the lease terms, all roommates can be evicted.
The legal principle extends to cosigners as well. Cosigners are often held to the same joint and several liability standard.
City of Pittsburgh Occupancy Rules
Before searching for a place with multiple roommates, be aware that Pittsburgh city code limits the number of unrelated individuals who can share a rental unit. The city allows no more than three unrelated people to live in one rental housing unit, regardless of the number of bedrooms.
Refer a tenant, get $100

This rule has important consequences:
- If you exceed the limit, someone will not be on the lease. This puts that person at risk without legal protection.
- Leaseholders bear full responsibility. If an unlisted roommate does not pay rent, the tenants on the lease have no choice but to cover that portion.
- Landlords may enforce the limit. Some landlords strictly adhere to this rule and will refuse to rent to groups of four or more unrelated individuals.
Practical Steps for Roommates
Before Signing the Lease
Discuss living habits with potential roommates. Talk about cleanliness preferences, noise levels, temperature preferences, and guest policies before committing to a year-long lease.
Decide how rent will be divided. Most roommates split rent evenly, but this gets complicated when rooms vary in size or when someone has a private bathroom. Discuss these details objectively and document the agreement.
Designate one person to collect rent. Having one roommate in charge of collecting payments ensures that all tenants are paying on time.
Documentation and Agreements
Use a roommate agreement. A roommate agreement is a written arrangement between co-tenants that sets expectations for rent payments, shared duties, and house rules. This is separate from the lease with the landlord and can include:
- Each roommate’s rent contribution
- Utility payment responsibilities
- Security deposit shares
- Cleaning schedules
- Guest policies
- Pet rules
- Procedure for replacing a departing roommate
Consider lease structure. Some landlords offer the option to choose one roommate as the primary leaseholder, with others as sublessees. This means the primary leaseholder has sole responsibility for upholding the lease. Alternatively, all roommates can be listed as co-tenants.
Name all adult residents on the lease. If an adult living in the property is not on the lease, they cannot be held accountable for rent or damages. Landlords typically require all adults to be on the lease. If a tenant moves in or out, the lease should be amended accordingly.
Understanding Your Legal Obligations
Breaking a lease. Pennsylvania law allows tenants to be held liable for all rent remaining on the lease if they leave before the term ends. Landlords have no legal obligation to re-rent the unit to reduce the tenant’s responsibility.
Notice periods. For lease violations in a lease shorter than one year, landlords must provide a 15-day Notice to Cure or Quit. For longer tenancies, 30 days’ notice is required.
Self-help evictions. Pennsylvania strictly prohibits landlords from using lockouts, utility shutoffs, or intimidation tactics to remove tenants.
