Delaware County, Pennsylvania Eviction Risk: Moderate

Delaware County carries an average eviction-risk score of 4.7/10 (Moderate), placing it second out of 67 counties in Pennsylvania, meaning only one county in the state posts a higher risk score. For landlords and investors, that ranking is a concrete warning: 65 of Pennsylvania's 67 counties are less risky to operate in than Delaware County. Across its 42 cities, conditions range from genuinely manageable to some of the most challenging in the state, with a wide band from 3.5 to 7.8. With a 36.9% renter share and an average rent of $1,401, this is a dense, rental-heavy suburban market where vacancy turns fast but eviction exposure is real.

The rent-burden figure sharpens that picture: tenants here spend an average of 32.8% of income on housing, a threshold that leaves little cushion when income disrupts. Combined with a 13.4% poverty rate, landlords should expect non-payment to be the most common default trigger and should underwrite accordingly. These are not credentials for avoiding Delaware County, but they are credentials for operating it carefully, with conservative tenant screening and a clear-eyed view of the eviction timeline Pennsylvania law actually imposes.

The cities inside Delaware County

Risk inside Delaware County is hyper-local, and the spread between its safest and most exposed markets is nearly as wide as a full state range. Yeadon, with a population of 12,181, leads the county at 4.5/10, the same score as the county maximum. Darby (pop. 10,687) follows immediately at 6.4/10, and Chester, the county's largest city at 33,619 residents, sits at 6.4/10. Linwood, Colwyn, Sharon Hill, and Marcus Hook all cluster between 7.5 and 7.6, forming a band of high-exposure submarkets that require the most disciplined underwriting and the fastest response to delinquency.

At the other end, Villanova scores 4.7/10, the county floor, indicating meaningfully lower eviction-risk fundamentals even within the same county boundaries. Broomall comes in at 4/10, and Drexel Hill at 4.4/10, both sitting below the county average despite being among its most populated communities. An investor comparing two properties ten minutes apart in Delaware County may be looking at a full two-point score difference, which translates directly to different expected vacancy, delinquency, and legal-cost profiles.

State-level laws that apply here

Every landlord in Delaware County operates under the Pennsylvania Landlord and Tenant Act of 1951, codified at 68 P.S. § 250.101 et seq. Notice requirements vary by the reason for termination: nonpayment of rent requires a 10-day written notice under 68 P.S. § 250.501(b); a material lease breach during a tenancy under one year requires 15 days, while a tenancy of one year or more requires 30 days, both under 68 P.S. § 250.501(a). Lease-end terminations require no statutory notice period. Understanding the Pennsylvania eviction process in full means accounting for the full timeline after those notice periods expire: uncontested cases run 30 to 60 days from filing; contested matters can extend to 60 to 150 days.

On the cost side, court filing fees in Pennsylvania run $130 to $250, sheriff lockout fees add $50 to $150, and attorney fees range from $500 to $3,000 depending on complexity. Pennsylvania eviction costs are therefore real and variable, especially if a tenant contests. The state does not require just cause to terminate a tenancy, and Pennsylvania preempts local rent-control ordinances, meaning no municipality in the county can impose a rent cap. Source-of-income is not a protected class under state law, though landlords should verify any local human-relations ordinances independently.

With 13.4% of residents below the poverty line and renters making up 36.9% of households, the fundamentals that drive eviction risk are present across Delaware County at above-average levels; use the city grid above to identify which specific markets fall inside or outside your risk tolerance before committing capital.
