Office Space in Washington DC — Common Questions
Everything you need to know about renting office space at OSI Offices on K Street NW in downtown Washington DC.
Office space costs in Washington DC vary widely based on location, size, and lease type. Traditional leases in the K Street corridor can run $50–$80+ per square foot annually. At OSI Offices, you can skip the long-term lease entirely — private offices start at competitive monthly rates with no deposits, no setup fees, and flexible month-to-month agreements. Virtual office plans begin at just $35/month if you only need a business address and mail handling.
Yes. OSI Offices offers conference rooms starting at $18/hour, making it easy to book space for a client meeting, deposition, interview, or team session without committing to a monthly plan. Private day offices are also available for those who need a quiet, professional workspace for a full day. All hourly and daily rentals include high-speed Wi-Fi, a presentation display, and access to our staffed reception area at 1629 K Street NW.
Shared office space at OSI includes a professional workspace in our K Street building along with high-speed Wi-Fi, mail handling with AI-powered scanning, access to conference rooms, printing and scanning equipment, a staffed reception to greet your guests, kitchen and lounge areas, and a prestigious business address you can use for your company. There are no hidden fees — utilities, cleaning, and building maintenance are all covered in your monthly rate.
Not at OSI Offices. All of our plans — virtual offices, shared desks, and private offices — are available on flexible month-to-month agreements with no long-term commitment required. There are no deposits and no setup fees, so you can scale up or down as your business needs change. This is a major advantage over traditional commercial leases in DC, which typically require multi-year commitments and significant upfront costs.
K Street NW is widely regarded as one of DC's most prestigious business corridors, home to major law firms, lobbying organizations, nonprofits, and government affairs consultancies. OSI Offices is located at 1629 K Street NW — just steps from the Farragut North and Farragut West Metro stations, making it one of the most accessible and recognizable business addresses in the city. The central downtown location puts you within walking distance of the White House, Georgetown, and Dupont Circle.
