フィラデルフィアのレンタルオフィススペース – レンタルオフィスとコワーキング

In 2025, the citywide average asking rent reached a record high near $32 per sq ft per year. Prime areas such as Market Street West run around $34–50, University City around $38–55 (reflecting life-sciences space), Rittenhouse Square around $30–42, and Market East and Old City around $27–34. Suburban Class A runs around $30–42 and fringe neighbourhoods start near $25. Center City space is usually quoted full-service (including operating costs). Coworking desks start at around $8 per person per day and serviced suites from around $219 per person per month.

Market Street West offers the most prestigious Class A and trophy addresses in the core. Rittenhouse Square combines a walkable, amenity-rich location with better value, while Market East and Old City suit finance, law, and professional-services firms. University City is the hub for life sciences and research, the Navy Yard offers modern campus-style space, and the fringe neighbourhoods and suburbs offer the most approachable rates.

Serviced suites and coworking spaces are generally furnished and ready to use, often within days. A traditionally leased floor takes more time for build-out — usually from a few weeks to several months, depending on the work involved.

Full-service (gross) rent bundles operating expenses — maintenance, common areas, janitorial, and a share of taxes — into a single per-square-foot figure, which is how most Center City space is quoted. Triple-net (NNN) quotes a lower base rent to which you add operating expenses and taxes separately. Philadelphia's local Use and Occupancy tax is typically passed through to tenants under either structure.

Coworking and serviced suites suit startups, small teams, and anyone seeking flexibility without a long-term commitment. A traditional lease makes sense for established companies with a stable footprint that need their own address and a customised layout.
