Commercial Lease Dispute Resolution: A Disagreement With Your Landlord, in Order
Commercial lease dispute resolution starts with the lease, not with a lawyer's letter. Most disagreements between an office tenant and a landlord concern an operating expense bill, a service or repair, a sublet request or a deposit, and most end when the tenant works in order: reread the clause and the notice provision, document the problem, raise it in writing, and use the remedy the lease already contains. Bring in your broker and a New York real estate attorney before taking any step that could look like a default. Keep paying rent throughout. Where talks fail, the lease says whether mediation, arbitration or the courts come next.

The four disputes office tenants run into after move-in
- An operating expense bill. The yearly statement is higher than expected, or includes charges that look like capital work.
- Services and repairs. The air conditioning does not hold temperature, an elevator is out, or cleaning falls short of the lease.
- A sublet or assignment request. You asked for consent and heard nothing, or were refused without a reason.
- The security deposit. The lease has ended and the money has not come back, or restoration was deducted and you dispute it.
Each has its own clause, and each clause has its own remedy.
The order to work in, from the lease to written notice
- Reread the lease. Find the clause that governs the problem, then the notice clause, which says how a formal notice must be delivered, to what address and with copies to whom. A notice sent the wrong way can lose the argument before it starts.
- Document. Keep a dated record: photos, the email thread, work order numbers from the building, and readings or logs if the complaint is about temperature or service.
- Raise it in writing. Begin with the building manager, then the landlord, and cite the clause.
- Use the tool the lease gives you. An audit right for an expense statement. The consent standard and any response deadline for a sublet request. A cure period for repairs and services.
For an expense dispute, operating expenses explains the base year, your share and the year-end statement you would be auditing.
When the broker and the attorney come in
Call your broker once a written request has gone unanswered. A broker knows how the landlord's side works and how similar disagreements have settled. If the complaint is really about maintenance, people who already run the floor can fix it faster than a letter can; our facilities management team covers the offices we run.
Call a New York real estate attorney before you withhold anything, before you send a notice that alleges a default, and as soon as you receive one. The remedies under New York law, and their deadlines, are the attorney's to advise on. This page is not legal advice.
Mediation, arbitration or the courts: the lease decides
If direct talks fail, look for a dispute resolution clause. Some leases provide for mediation first. Some send a particular disagreement to arbitration; a renewal rent set at fair market value, for instance, often comes with an appraisal or arbitration step. Where the lease is silent, what is left is litigation, a decision to take with your attorney.
Keep paying rent, and prevent the next dispute at signing
Do not withhold rent as a protest. Most leases treat non-payment as a default, and a tenant in default has handed the landlord the better position, whatever the merits of the original complaint. Pay, object in writing and protect your position the way your attorney advises.
Most disputes trace back to something the lease left undefined. An audit right, a deadline for the landlord to answer a consent request, a list of services with their hours, a defined restoration scope and a stated date for returning the deposit each remove an argument before it can start. Lease red flags lists what to catch before signing.

Can I deduct a disputed charge from my rent?
Not without your attorney's advice. Most leases treat any shortfall as a default, including one the tenant believes is justified. Pay, object in writing within the time the lease allows, and pursue the audit or remedy the lease provides.
What if the landlord will not return the security deposit?
Start with the lease's own terms: the deadline for return, if one is stated, and what the landlord may deduct. Ask in writing for an itemized account of any deduction, and send the request the way the notice clause requires. Security deposit covers what to negotiate next time.
My sublet request has gone unanswered. What can I do?
Check the clause for a consent standard and a response deadline. If consent may not be unreasonably withheld or delayed, send a written reminder that cites the clause. If the clause sets neither, the decision rests with the landlord, and your attorney should advise before you act.
