Subleasing Commercial Space: Guide for Tenants & Landlords

Common Situations When Subleasing a Commercial Property Makes Sense

A signed commercial lease is a long-term commitment. It works well when your business occupies the space as planned. But circumstances can change when companies downsize, relocate, or outgrow their footprint before the lease term ends. On the other side of the transaction, landlords receive sublease requests that can either be straightforward approvals or complicated situations requiring careful review.

Subleasing commercial space is one of those areas where both parties have real stakes and limited margin for error. This guide walks through what both tenants and landlords need to understand before a sublease moves forward.

What Is a Commercial Sublease?

A commercial sublease is an arrangement where the original tenant (the sublandlord) leases all or part of their space to a third party (the subtenant) for a period that falls within the remaining term of the primary lease.

The critical distinction: the original tenant doesn’t exit the lease. The primary lease stays in place, and the original tenant remains financially responsible to the landlord, even if the subtenant stops paying rent, vacates, or causes damage. The subtenant has a legal relationship with the original tenant, not directly with the building owner.

That arrangement has real consequences for how both parties need to approach it.

The Tenant’s Side: When to Consider Subleasing Commercial Property

Situations That Typically Drive Sublease Decisions

Tenants explore subleasing for a few common reasons. A merger or acquisition leaves you with more space than your headcount requires. Remote work policies have shifted your actual occupancy well below what you’re paying for. A satellite office is being consolidated into your headquarters. In each case, subleasing offers a way to offset lease costs without walking away from the space entirely.

Before pursuing a sublease, be clear on two things: what your lease actually permits, and what you’re taking on by staying on the hook as the primary tenant.

Reviewing Your Lease Before You Do Anything Else

Most commercial leases require landlord approval before subleasing. Some are written as “consent not to be unreasonably withheld” provisions, which gives tenants a reasonable baseline, meaning the landlord can’t reject a qualified subtenant arbitrarily. Others give landlords broader discretion or even a right of recapture, meaning the landlord can terminate your lease rather than approve the sublease.

Read your lease carefully before approaching a potential subtenant. Specifically, look for:

Sublease consent language: What approval process is required, and what standards apply
Recapture rights: Whether the landlord can take back the space instead of approving a sublease
Permitted use provisions: Whether your intended subtenant’s business fits the use clause
Assignment clauses: Sometimes grouped with sublease language, these are treated differently (more on that below)

If the language is ambiguous or the lease is complex, get guidance before committing to a subtenant. Moving too far into negotiations without landlord alignment wastes time for everyone.

How Sublease Rent Is Structured

Sublease rent is negotiated between you and the subtenant independently of your primary lease rate. In a strong market, a subtenant might pay close to or above your current rent. In a soft market or when you’re offering a shorter remaining term, you may need to price below your lease rate to attract interest.

If the sublease rent exceeds what you’re paying under the primary lease, most commercial leases include a profit-sharing provision that gives the landlord a portion of that overage. Check yours or consult with a tenant representation expert before pricing the sublease.

Whatever the rate, document the sublease agreement thoroughly. It should address rent obligations, maintenance responsibilities, permitted use, insurance requirements, and what happens if either party defaults.

You’re Still on the Hook

This point deserves emphasis. If your subtenant stops paying rent or vacates the space, your obligation to the landlord doesn’t pause. You still owe rent under the primary lease. That exposure means you should vet subtenants as carefully as a landlord would vet a new tenant, including financial statements, business stability, and a realistic read on whether they’ll occupy the space for the sublease term.

A well-structured sublease agreement gives you remedies if the subtenant defaults, but the cost and friction of pursuing those remedies underscore why getting the subtenant selection right from the start matters.

Not sure what your lease actually allows? Subleasing decisions start with your lease language. Hokanson’s tenant representation team can review your situation and give you a straight answer on where you stand before you commit to anything.

The Landlord’s Side: Protecting Your Asset When a Sublease Request Arrives

What a Sublease Request Actually Triggers

When a tenant submits a sublease request, your first step is to pull the lease and understand what your approval rights require. If you have a right of recapture, evaluate whether taking the space back serves your interests, particularly if the market is strong and you could re-tenant at current rates. If you’re evaluating approval, you’re effectively underwriting a new occupant for your building even though they’re not your direct tenant.

The questions worth asking before approving:

Is the proposed subtenant financially qualified? The original tenant remains on the hook, but you want to know whether the subtenant can actually occupy the space. A subtenant who fails means a vacant space, potential damage, and a distressed original tenant.
Does the proposed use align with your lease and your building? Permitted use clauses in the primary lease typically flow down to the subtenant. Confirm the subtenant’s intended use doesn’t conflict with exclusivity provisions you’ve granted to other tenants.
Does the space configuration work? If the tenant is subleasing only a portion of their space, consider how that affects building access, common area usage, and any shared systems.
What does the sublease agreement look like? You’re not a party to it, but you may have the right to review it before approving. A poorly drafted sublease that doesn’t mirror the primary lease’s key obligations can create disputes that eventually land in your lap.

What Happens If the Subtenant Defaults

When the subtenant stops paying the original tenant, your direct relationship is with the original tenant, not the subtenant. The original tenant is still responsible for rent under the primary lease. In practice, a subtenant default often creates a cash flow crisis for the original tenant, which can cascade into a default on the primary lease.

If the original tenant defaults, your remedies under the primary lease are unaffected by the sublease. Depending on how the sublease was structured and your jurisdiction, you may be able to step into the sublease relationship directly in certain scenarios, but this is case-specific and worth understanding before an issue arises.

The practical takeaway: don’t treat sublease approval as a passive event. Review the proposed subtenant, understand the sublease structure, and make sure your lease protections are clearly intact.

Commercial Lease Sublease vs. Assignment: Understanding the Difference

A sublease and a lease assignment are often conflated, but they’re structurally different and carry different implications.

In a sublease, the original tenant stays in place. They become a sublandlord, their lease with you continues, and they’re still directly responsible for all primary lease obligations.

In a lease assignment, the original tenant transfers their entire interest in the lease to a new party. If you approve an assignment and release the original tenant, you’re essentially re-tenanting the space. Your new tenant is the assignee, and depending on how the assignment is structured, the original tenant may have no further obligation.

Assignments are often cleaner from the original tenant’s perspective (they exit the lease entirely), but they require more diligence from the landlord because the original tenant’s creditworthiness is no longer backstopping the deal.

Which approach makes more sense depends on the circumstances: how much lease term remains, the relative creditworthiness of the original tenant versus the proposed new occupant, and what the market for that space looks like. Neither option is automatically better. Instead, it depends on what each party is actually trying to accomplish.

Frequently Asked Questions About Subleasing a Commercial Property

Does my landlord have to approve a commercial sublease agreement?

In most cases, yes. Commercial lease negotiations typically require landlord consent before a sublease can be executed. Some include language stating that approval won’t be unreasonably withheld, which limits the landlord’s ability to reject a qualified subtenant arbitrarily. Others give landlords broader discretion or even the right to recapture the space instead of approving. Your specific lease language controls, so review it carefully before you approach any potential subtenants or draft a commercial sublease agreement.

How do I sublease office space if I still have years left on my lease?

Start with your lease, not with a subtenant search. Understanding how to sublease office space begins with confirming what your lease actually permits: consent requirements, permitted use restrictions, profit-sharing provisions, and any recapture rights. Once you know your parameters, you can identify a qualified subtenant, negotiate sublease terms, and submit the request for landlord approval. Moving in the wrong order (for example, lining up a subtenant before confirming your lease allows it) creates delays and strained relationships.

What if I sublease my space and the subtenant stops paying?

Your obligation to the landlord doesn’t stop. You remain responsible for rent under the primary lease regardless of what happens with your subtenant. This is one of the key risks of subleasing, and it’s why subtenant vetting and a well-drafted sublease agreement matter.

Can a landlord refuse a sublease request?

It depends on the lease. Many leases give landlords the right to withhold consent or to recapture the space instead of approving the sublease. If your lease has a recapture provision, the landlord can effectively terminate your tenancy rather than approve a sublease.

How is sublease rent determined?

Sublease rent is negotiated between the original tenant and the subtenant. It doesn’t have to match the primary lease rate, but if the sublease rent exceeds what you’re paying, many primary leases require you to share that overage with the landlord. Review your lease for profit-sharing provisions before pricing the sublease.

Why Both Sides Benefit From an Experienced Advisor When Subleasing Commercial Property

The mechanics of a commercial sublease aren’t complicated in isolation. What creates problems is when tenants don’t fully understand their lease exposure before committing to a subtenant, or when landlords approve a sublease without a clear read on the proposed occupant or the downstream risks.

An advisor who works on both sides of commercial transactions brings a practical advantage here. Hokanson has represented tenants navigating lease obligations and landlords managing their portfolios since 1938, and because our brokerage and property management practices are integrated under one firm, we understand how the same transaction looks from either side.

If you’re a tenant looking to sublease space you’re no longer fully using, we can help you review your lease, assess your exposure, and structure a sublease that limits your risk while finding the right subtenant. If you’re a landlord reviewing a sublease request, we can evaluate the proposed transaction against your asset goals, help you vet the incoming occupant, and make sure your lease protections remain intact.

Either way, the objective is the same: a clear path forward that protects your position.
