Free Office Sublease Agreement Template

An office sublease agreement is a contract where a company rents its leased office space, or part of it, to another business.

The company holding the original lease keeps that lease. It simply becomes the landlord for the new occupant, collecting rent and passing along the building’s rules.

Office deals carry their own texture. Desks, conference rooms, reception areas, and server closets get divided in ways a warehouse or storefront never requires. So the paperwork spends most of its detail on shared space and shared services.

Size varies widely. Some cover four desks in a corner, while others hand over a full floor with its own elevator lobby.

Furniture usually travels with the deal. That is why an inventory list matters more here than in almost any other lease.

Hybrid schedules left many businesses paying for desks nobody occupies.

Common reasons to sublet include:

• A team that shrank after a reorganization.
• A lease signed for headcount that never arrived.
• A move to a smaller footprint with years remaining on the old term.
• A company consolidating two locations into one.
• A satellite office that closed when travel patterns changed.

Subtenants come looking for different things. Growing companies want a furnished suite without a five-year commitment. Project teams want twelve months near a client. Meanwhile, remote-first firms want a few days a week of real desks.

That mismatch is exactly why these deals close quickly once the terms are clear.

Timing helps as well. A sublease can start in weeks rather than months. The space is already built out, and the furniture is already there.

A good office sublease earns its keep by settling shared details in advance.

Suite and Desk Count

Identify the floor, suite number, and specific rooms or workstations included. Attach a floor plan with the subleased area marked.

Sublease Term

Set the start and end dates, then confirm both fall inside the original lease term. Also note any early termination rights.

Rent and Operating Costs

List the monthly rent and what it covers. Office buildings pass through cleaning, utilities, and common area charges. So state which of those the subtenant pays and how each share is calculated.

Furniture, Phones, and Internet

Decide whether desks, chairs, monitors, and network access come with the space. Then attach an inventory list, since equipment disputes usually start with memory rather than malice.

Shared Amenities

Conference rooms, kitchens, printers, and reception coverage all need booking rules. In addition, say how many parking spaces and access cards the subtenant receives.

Building Rules and Hours

Note quiet hours, after-hours HVAC charges, guest policies, and loading dock access.

Deposit and Insurance

Record the security deposit and the coverage each party carries, including who must be named on each policy.

Condition at Move-Out

Describe the state the subtenant must leave behind, especially after cabling, wall mounts, or branded signage.

Your sublease can only offer what the original lease already gives you.

Read that lease first. Its consent clause usually requires the building owner’s written approval. It also sets a response window and lists what the owner may ask about an incoming business. Gather that material before you request anything.

Watch for three clauses in particular. Use restrictions can rule out a subtenant’s business type. Profit-sharing language can hand the owner part of any rent above your own. Alteration rules can block the layout changes a subtenant expects.

Keep the approval in writing. If the building sells or the management company changes, a saved consent letter is the only proof that survives.

Never let a subtenant move in on a handshake while approval is still pending.

Check the notice provisions too. Many leases ask for a copy of the signed sublease within a set window after both parties sign.

A few checks now prevent the problems that surface months later.

Local rules are not uniform across states or municipalities. Therefore, check your state’s official website for guidance on commercial leasing. Then ask the local zoning office whether the subtenant’s business fits the address.

Building management holds answers the lease does not. Ask about after-hours access, freight elevator booking, directory listings, and whether the subtenant may post signage in the lobby.

Confirm the remaining term on the master lease as well. Subtenants planning to stay past that date should learn it now, not during their second year.

Heavy build-out or a multi-year sublease raises the stakes. In those cases, ask a commercial real estate attorney to read the document first.

With consent secured, the last steps move fast.

1. Collect the master lease, the written consent, the floor plan, and the furniture inventory.
2. Work through the step-by-step questionnaire covering rent, term, shared costs, and amenities.
3. Attach the floor plan and inventory as exhibits.
4. Review the draft together and fix anything that does not match your conversation.
5. Download your office sublease agreement as a PDF or Word file, then sign and share copies.

Handle access on day one. Cards, alarm codes, wifi credentials, and directory updates all belong on a short checklist. Sorting them early sets a good tone.
