How Philadelphia compares to peer metros
When evaluating Philadelphia against peer metros for a 5-year Class A office lease, three comparisons matter:
- Effective rent vs asking: in Philadelphia Q1 2026, the asking-vs-effective spread depends on submarket vacancy. Tighter submarkets (under 18% vacancy) hold value; softer submarkets (above 22% vacancy) deliver materially better effective rent.
- Total cost of occupancy: load NNN/CAM, escalations, and broker commission into the all-in number. Philadelphia’s blended TCO loading factor is in the 28 to 35% range typical of major US metros per the CBRE Total Cost of Occupancy framework.
- Workforce concentration: pull BLS Quarterly Census of Employment and Wages data for your specific industry’s employment in the Philadelphia MSA. Cheap rent in a market without your sector’s talent pool is a hiring trap.
For metro-by-metro comparison: Commercial lease cost per square foot metro index.
When to engage a tenant rep broker for a Philadelphia deal
For Philadelphia deals over 1,000 SF, engage a tenant rep broker. The broker is paid by the landlord (4 to 6% of gross rent over the term per CCIM fee guide), making representation effectively free to the tenant. Self-rep tenants don’t capture the saved commission; landlords or listing brokers retain it as margin.
For Philadelphia specifically, prioritize brokers with submarket experience in your specific area of the metro. Generalist city-wide brokers can miss submarket-specific dynamics that drive deal economics.
