Why Government Contractors Choose K Street
K Street is the epicenter of government contracting in Washington DC. A business address at 1629 K Street NW places your firm within walking distance of the General Services Administration (GSA), the Office of Personnel Management (OPM), the World Bank, the International Monetary Fund (IMF), and dozens of other federal agencies and contracting offices.
When contracting officers review your bid, your address signals permanence and proximity. A K Street presence communicates that your firm is established, accessible, and committed to the DC market — not operating from a residential address or a P.O. box in the suburbs.
OSI Offices provides the infrastructure government contractors need without the overhead of a traditional office lease. Use your K Street address on SAM.gov registrations, CBE applications, CAGE code filings, and proposal cover pages. Meet contracting officers and teaming partners in professional conference rooms steps from the Metro.
With two Metro stations within a block — Farragut North (Red Line) and Farragut West (Blue/Orange/Silver Line) — your clients and partners can reach you easily from anywhere in the DC metropolitan area.

Compliance
CBE and SAM Compliance
Our Dedicated Desk plan is specifically designed to meet the physical nexus requirements for DC government certifications and federal registrations.
Washington DC's Certified Business Enterprise (CBE) program requires businesses to demonstrate a physical presence in the District. A P.O. box or mail-only address does not satisfy this requirement. OSI's Dedicated Desk plan provides a real workspace with a lease agreement and a copy of OSI's own Certificate of Occupancy for our suites at 1629 K Street NW, Suite 300 — the lease and certificate of occupancy DSLBD lists as principal-office proof for CBE certification. If DSLBD or another agency asks for a certificate issued in your own business name, you can apply to the DC Department of Buildings yourself; OSI provides owner consent and hosts the inspection for a one-time $150 coordination fee.
For federal contracting through SAM.gov, your business needs a verifiable physical address tied to your CAGE code and Unique Entity Identifier (UEI), formerly the DUNS number. OSI provides the address verification and supporting documentation needed for these registrations.
Whether you are applying for CBE certification, registering in SAM.gov, obtaining a CAGE code, or updating your UEI, OSI Offices provides the lease agreements, address verification letters, and Certificate of Occupancy documentation required to support your application. Our team has supported hundreds of government contractors through this process over 45 years in business.

FAQ
Government Contractor Questions
Common questions from government contractors about OSI's virtual office solutions in Washington DC.
Getting started
You can start from home. What you cannot do from home is put a residential address on an LLC filing, a SAM.gov registration, an investor deck, or a proposal cover page without it costing you credibility. A K Street business address with mail service is $65/month — currently $32.50/month for your first six months — with no space commitment, so you look established on paper from day one while your burn stays near zero. Most contractors start there and add workspace when a certification or the calendar demands it.
Signup is same-day, and there is no build-out, furniture order, or deposit to clear. Before we can receive mail on your behalf, USPS requires a notarized Form 1583 and two forms of ID — a federal rule for every mail-receiving service, not an OSI hurdle — and most people clear it in a day or two. If you are racing a proposal deadline or a certification window, call (202) 600-7777 and say so.
You get 1629 K Street NW, Suite 300: a suite number in a specific office building, not a box number at a retail mail store. There is a staffed reception, a real office someone can visit, and a lobby directory listing is available for $10/month. That is a materially different signal from a mailbox-store address, which many federal agencies will not accept as a principal place of business.
Business registration and licensing
Yes. Our 1629 K Street NW address is used for DC business registration with DLCP (formerly DCRA), and OSI holds its own DC Certificate of Occupancy for its suites, a copy of which we provide to support licensing requirements. This is the single most common reason founders come to us: it lets you form and license the entity without putting your home address into a public database.
Largely, yes — that is the point. Business registrations, registered agent filings, and SAM.gov entity records are searchable by anyone. Using our address on those filings means vendors, litigants, and data brokers see K Street instead of your street. Some filings still require personal information that we cannot shield, so check what your specific registration demands.
Yes. Registered agent service is $5/month per entity plus a one-time $25 setup fee, available with any active mail plan. We receive legal documents, tax notices, and government correspondence served on your entity during business hours, log them, and alert you the same day. Miss a service-of-process notice and you can lose a case by default; that is the risk the $5 is buying down. See our registered agent page.
Yes. Once you have signed up for mail service and submitted your notarized Form 1583, we provide a copy of OSI's own DC Certificate of Occupancy for our suites at no charge, for licensing, banking, and regulatory filings. If an agency specifically demands a certificate issued in your business's name, that requires a DC Department of Buildings inspection; we provide the owner consent and host the inspection for a one-time $150 coordination fee.
Virtual office fees are generally treated as an ordinary and necessary business expense, and members commonly deduct them. Rules vary by entity type and by how you use the space, so confirm your situation with your accountant. Our client community includes independent professionals who do tax, formation, and finance work, and members tell us that network is one of the more useful things about the building.
Government contracting: SAM, CAGE, UEI, and CBE
SAM.gov requires a verifiable physical address tied to your CAGE code and UEI; a P.O. box will not clear it, and many agencies reject mailbox-store and residential addresses as a principal place of business. Our address plans meet that requirement, and SAM itself does not ask for a Certificate of Occupancy. Send us your business name exactly as registered in SAM.gov and we prepare the lease naming Suite 300. During our 45 years, many clients have obtained SAM.gov registrations and DLA CAGE codes from this address, though every approval is at the discretion of the agency. Learn more about CBE and SAM compliance.
Yes, and this is the plan-selection question that matters most. The District requires that your principal office be physically located in DC with managerial functions performed from it, so a mail-only address does not qualify. A dedicated desk at 1629 K Street NW, Suite 300 — from $340/month with 24/7 access, or $500/month with live phone answering and digital mail — provides the real workspace, and we prepare a signed 12-month agreement identifying it, which is the lease term DSLBD looks for, along with a copy of our Certificate of Occupancy. We have worked with DSLBD's certification process for many years and their team is familiar with OSI. We supply documentation and practical guidance; we are not a law firm or a certification consultancy, and the filing remains yours.
Yes. For businesses that want to try the workspace before committing to the standard six-month minimum, we offer a three-month prepaid introductory dedicated desk for $900.
A lease agreement in your registered business name, a copy of OSI's Certificate of Occupancy, and an address verification letter on OSI letterhead — the package that supports CAGE code applications, UEI registrations, CBE filings, DC Basic Business License applications, and proposal submissions. One lease document is included with each account; additional leases are $35 each.
Walking distance to the General Services Administration, the Office of Personnel Management, the World Bank, and the IMF, with dozens of federal offices and contracting shops in between. Two Metro stations sit within a block: Farragut North on the Red Line and Farragut West on the Blue, Orange, and Silver Lines. For a business built on industry days, debriefs, and teaming coffees, the walk time is a real operational advantage.
Yes, and it is a common use of the space. Reserve a conference room for capability briefings, proposal walkthroughs, oral presentation rehearsals, or teaming discussions. Visitors arrive at a staffed front desk rather than a locked suite door, which is the difference between looking like a company and looking like a laptop. Organizations do not need to be U.S.-based to reserve workspace or meeting rooms with us.
Meetings, workspace, and growth
Three room types, each with high-speed Wi-Fi, a large display, and a whiteboard: a small conference room for 2 to 4 people ($18/hour for members), a large conference room for 6 to 12 ($22/hour), and the executive boardroom for 12 to 30 ($94/hour). The Starter Package includes two prepaid hours a month and the Comprehensive Plan includes sixteen; additional office time is $18/hour on address plans and $14/hour on plans with prepaid hours.
The $279/month desk includes business-hours access (Monday to Friday 7:30 AM to 9:00 PM, Saturday 9:00 AM to 6:00 PM) with mail service. The $340/month desk adds 24/7 key-card access and five hours of meeting space, and the $500/month desk adds live phone answering and digital mail scanning. Desks carry a six-month minimum term; you are welcome to leave your own monitors set up, and a locker can be added for $25/month.
You expand in the same building, at the same address, with the same phone number: no rebranding, no reprinting, no change-of-address filings across your registrations right when you can least afford the distraction. The path runs from virtual address to dedicated desk to furnished private office, from $700/month interior or $1,250/month with a window, with 24/7 building access for late proposal nights. That continuity is worth more to a growing contractor than most people expect until they have moved once.
You scale down without renegotiating anything. Mail plans are month-to-month with no security deposit and no exit fee, and mail-only service can end at the close of the current month. Giving up a desk or office takes 30 days' notice. The decision to add or drop space does not require board approval or a real estate attorney, which is the argument for flex space over a five-year lease when your headcount could double or halve within twelve months.
Yes. Tell us how many people need daily desk access and how often, and we will build the plan around that rather than selling seats nobody uses. Furnished private offices are available with 24/7 building access, and we can authorize additional team members to receive and collect mail.
Mail, phones, and daily operations
Staff receive and sort mail daily and accept packages from every carrier, notifying you at the email on file when something arrives. Digital scanning of the envelope front is a $15/month add-on that pushes images to your email and the client portal in real time; open-and-scan of the contents is $2 per envelope. Forwarding goes out twice weekly for $5/month plus postage at cost plus 25%, so a contract modification or an agency letter reaches you the day it arrives, wherever you are.
Yes. A dedicated 202 number with voicemail-to-email transcription is included from the $99/month Starter Package. Live receptionist answering in your company name, with calls relayed to you, comes with the $115/month Phone and Mail plan or as a $20/month per-line add-on; automatic forwarding to your own number is $25/month. Callers reach a person, not a recording — something most flex-space providers do not offer at all.
OSIntelligence, our 24/7 AI receptionist, runs a sales-inquiry agent that qualifies prospects on service interest, company size, and decision timeline, and routes vendors and cold callers to voicemail. You come in to a queue of real leads instead of forty minutes of triage. Live K Street staff back it up during business hours.
Cost, terms, and comparison
$35/month Office Hours: three hours of private office use a month and member meeting-room rates, without mail service or use of the address. $65/month Enhanced Mail: the K Street address with professional mail handling, SAM-ready ($32.50 for your first six months). $99/month Starter: address, mail service with scanning, DC phone number with voicemail-to-email, two prepaid office hours ($49.50 for your first six months). $115/month Phone and Mail: adds live receptionist answering. $165/month Comprehensive: sixteen prepaid hours. Dedicated desks at $279, $340, and $500/month with a lease agreement and Certificate of Occupancy copy for CBE and SAM filings. See plans and pricing.
No security deposit, no setup fee, no long-term contract on mail plans, and no termination penalty. Registered agent carries a one-time $25 setup fee, and postage on forwarded mail is billed at cost plus 25%. Pay a year ahead and take 10% off, or 5% off for six months.
The national brands typically want annual terms, charge separately for the services you will actually use, and cannot produce CBE-grade lease and occupancy documentation for a DC certification filing. OSI has been family-owned on the same corner since 1981 — the first executive suite in the United States — with month-to-month mail plans and a team that has walked hundreds of contractors through SAM and CBE paperwork. Founders who shopped both routinely tell us the deciding factors were price and the fact that a manager picks up the phone.
Monthly parking is handled by the building at about $275/month, and there are public garages within a block at 1601 K Street NW, 1050 17th Street NW, and 1667 K Street NW, plus limited metered street parking.
Yes. Request a free day pass and work here for a day, or book a tour. Take a call from a private office, watch how the front desk handles a delivery, and time the Metro walk yourself. Call (202) 600-7777, email manager@osioffices.com, or send a message and a real person in DC replies the same business day.
