Philadelphia Office Space for Rent — 133 Private Offices from $128/mo

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.

Most conventional office leases in Philadelphia are quoted full-service (gross): a single figure per square foot per year that already includes maintenance, common areas, janitorial and a share of property taxes, which is how most Center City space is quoted. A triple-net (NNN) lease quotes a lower base rent and adds operating expenses and taxes on top, so compare the all-in cost rather than the headline rate. Philadelphia's Use and Occupancy tax is normally passed through to the tenant under either structure. Serviced suites and coworking rooms work differently: you sign a short monthly or annual agreement for a furnished room, and the fee usually covers reception, utilities and internet. The listings on RentOfficeToday show the total monthly rent and the rate per square foot per month, so converting to lease language means multiplying by 12: a 1,163 sq ft private office at Two Logan Square listed at $3,024 a month is $2.60 per sq ft per month, or about $31 per sq ft per year. That matches the median across all 133 private offices for rent in Philadelphia and its suburbs on this page, $31 per sq ft per year; the cheapest listings are around $25 per sq ft per year and the most expensive small rooms reach $76. There is no broker fee for tenants.

In Philadelphia the choice is mostly about footprint and commitment, not the rate per square foot. A private office is a lockable suite used by your company alone; this catalog lists 133 of them in 18 Philadelphia-area buildings, from 43 sq ft at $128 a month to 27,373 sq ft at $71,204, with a median of $3,575 a month for about 1,378 sq ft. Shared office space — a coworking suite on a floor shared with other companies — is available in all 18 buildings: 40 suites from $384 a month for 129 sq ft, median $3,932. Both types work out to a median of about $31 per sq ft per year, so shared space does not undercut a private office on rate; what it offers is less area (half of the shared suites are 1,000 sq ft or under, at $384–$2,880 a month) and a shorter commitment. Choose shared space if your team is small, the headcount may change, or you need a Philadelphia address within days. Choose a private office if you need confidentiality, your own layout, or a larger floor plate: 38 private offices are 500 sq ft or under at $128–$3,060 a month, and 26 are 5,000 sq ft or larger at $12,386–$71,204 a month.

A virtual office in Philadelphia costs $100 to $150 per month on RentOfficeToday, and the median across the 18 business centers listed is $125. Four buildings offer a business address for exactly $100: the Hale Building at 100 South Juniper Street in Center City, CIRA Center at 30th Street Station in University City, 12 Penns Trail in Newtown and Saucon Valley Plaza in Center Valley. The most expensive addresses, at $150, are 325-41 Chestnut Street in Old City and Freedom Business Center in King of Prussia; One Liberty Place on Market Street is $140. A fuller virtual office plan that adds mail forwarding and meeting-room credits is listed at $120 at Two Logan Square and $150 at Saucon Valley Plaza. The monthly fee buys a street address you can use for invoices, company filings and a bank account, plus receipt of your mail; ask each center what mail forwarding, scanning, a Philadelphia phone number and room bookings cost, because those extras are priced building by building. For comparison, the smallest private offices in the same Philadelphia buildings start at $128 per month, so a virtual office is the right choice only when you need the address rather than a place to sit.

Yes, if you want a Center City address on the Parkway side of Market Street. Two Logan Square at 100 North 18th Street lists 7 private offices from 129 to 3,229 sq ft at $336 to $8,400 a month, all at about $31 per sq ft per year, plus a virtual office plan at $120. With One Liberty Place and 2001 Market Street a few blocks south, the area offers 19 private offices with a median rent of $3,024 a month and rates from $24.52 to $41.25 per sq ft per year, around the $31.22 median for all 133 private offices listed in Philadelphia.

Start with headcount and the common planning range of 150–250 sq ft per person, so a team of 10 needs roughly 1,500–2,500 sq ft. Then apply the rate: private offices listed for Philadelphia run from about $25 to $76 per sq ft per year, with the cheapest quarter under $28, the median at $31.22 and the most expensive quarter starting at about $36.80, so a 2,000 sq ft suite at the median costs about $5,200 a month. Add 10–20% if you expect to hire during the term, or take a flexible suite in a business center so you can move up a size without changing your address.
