Real Estate Brokerage Services for a Business That Has Outgrown Its Office

When a business outgrows its office in the middle of a lease, real estate brokerage services come down to a choice among three routes: take more space in the same building, add a second floor nearby, or move to a larger floor and sublet or assign the old one. We start by reading what your current lease already allows, price all three routes over the months you have left, and then run whichever wins. On your search, we work for you, and on the new space in most transactions the landlord pays the broker fee. The floors below fit about 70 people.

Price my three routes

Updated 2026-10-03 · Nomad Group

Three routes when the floor is full mid-lease

  • Expand in the building. It fits when your lease holds an expansion option or a right of first offer, or when the landlord has space coming free. You keep the address, nobody moves, and the landlord already knows your company.
  • Add a second floor nearby. It fits when a long term remains and the shortfall is modest. A furnished floor can be in use two to four weeks after its lease is signed. The price is a team in two places, with two pantries and two front doors.
  • Move and sublet the old space. It fits when the company needs everyone together, or when the team now lives somewhere the old address is awkward to reach. It carries the largest one-time cost, and the old lease still has to be dealt with.

What your existing lease already allows

Three clauses decide which routes are open, and we read them before anyone calls the landlord.

  • An expansion option names space you can add at set times and on set terms.
  • A right of first offer obliges the landlord to offer you named space before marketing it. It is a first look, not a fixed price.
  • The sublet and assignment clause sets whether you need consent, on what standard, and whether the landlord can take the space back when you ask.

Each right is used by written notice inside a window. Lease options explains the mechanics, and your attorney should confirm the dates in your lease.

Leaving the old floor: sublease or assignment

In a sublease you remain the tenant. A subtenant pays you, you keep paying the landlord, and you owe the lease until it ends. As the party marketing the space, you usually pay that commission.

In an assignment the lease passes to another company, which pays the landlord directly. It is the cleaner break, though the original tenant often stays liable if the new one defaults unless the landlord grants a release. That is a point for your attorney. Every way out of a lease compares the costs.

Choosing the neighborhood for the larger floor

Start from where the team lives now, which may not be where it lived when the first lease was signed. Then check which districts have floors of the size you need, because loft neighborhoods run short of large plates sooner than tower districts do. The floors below show what fits about 70 people, and how to choose a neighborhood covers the commute test.

What to compare across the routes besides rent

  • One-time costs: buildout beyond the allowance, furniture and cabling, the move, and a second deposit or letter of credit.
  • Overlap: the months you pay for two spaces.
  • What you still owe on the old lease after each route.
  • Time: 10 to 16 weeks is typical where the new space needs a custom buildout.
  • Whether the leases would end together, or leave you with two expiry dates to manage.

Can we add space in our building if the lease has no expansion right?

You can ask, and it is often worth asking first. Without a right in the lease the landlord has no duty to offer anything, so it becomes a negotiation, and it goes better when you already know what a floor elsewhere would cost.

Who pays the broker when we sublet the floor we are leaving?

Usually you do, as the sublandlord marketing the space, so count that commission when you compare the routes. On the lease for the new floor, in most transactions the landlord pays the broker fee.

Is a second floor in another building a bad idea?

Not always. It can be the fastest route. The cost is the split: two sets of shared rooms and a team that no longer overhears itself. Keep the second floor within a short walk, and match its term to the first lease's expiry where you can.

How soon should we act once the office feels full?

Before it is. A density of about 140 square feet a head is workable for a quarter or two, and past that the floor works against you. Because a move with construction takes months, start pricing the three routes when the hiring plan shows the floor filling, not when the last desk is taken.
