Can My Landlord Raise My Office Rent? RERA Calculator Rules for Commercial Leases (2026)

Short answer: yes, but not freely. A Dubai landlord can propose a higher office rent at renewal but only with written notice at least 90 days before your lease ends. Increases are also meant to follow the RERA rental index rules in Decree No. 43 of 2013, which limit how much rent can rise based on how far your rent sits below the market average.

One point is less settled for offices than most guides admit: whether the RERA calculator result is a hard legal cap on commercial rent, or a benchmark you can use in negotiation. This guide explains what the rules say, how to run the numbers, what notice your landlord must give and what you can do if the increase looks wrong.

It is written for Dubai mainland office tenants approaching renewal in 2027 and raises the same questions for retail and other commercial units.

Does the RERA rent calculator apply to offices?

Law No. 26 of 2007, as amended by Law No. 33 of 2008, governs landlord and tenant relationships for both residential and commercial property in Dubai, as Al Tamimi & Company explains. Decree No. 43 of 2013, which sets the rent-increase bands, refers to "real property" without limiting it to homes. The decree text has no carve-out for offices and no clause letting landlord and tenant agree a different cap.

The practical difficulty is the index behind the calculator. The Dubai Land Department's calculator now lists a commercial category, but published guides disagree on whether the Smart Rental Index legally caps commercial rent. One 2026 commercial lease guide reports that the index covers only residential property and advises using a commercial result as market evidence, not a ceiling. Others, such as Wasl, treat it as covering offices and shops.

Our advice: run the calculator, keep a screenshot, and treat the result as the benchmark both sides will be judged against. Confirm with the Dubai Land Department or a UAE lawyer before relying on it as a hard cap in a dispute.

Free zones are different. Leases inside DIFC and some other free zones often follow their own regulators. Check your lease and your landlord's licensing authority first.

How the RERA rent increase calculator works

The calculator compares your current rent with the average rent for similar units, then reads off the maximum increase from five bands. Under Article 1 of Decree No. 43 of 2013, the further your rent sits below the market average, the more your landlord can add at renewal.

These are ceilings, not entitlements. A landlord can ask for less, and a tenant can negotiate below the cap.

A worked example (illustrative figures, not market data). You rent a 1,000 sq ft office in Business Bay at AED 90,000 a year. The index average for similar units is AED 110,000. Your rent is about 18% below the average, which falls in the 11% to 20% band, so the maximum increase is 5%. That is AED 94,500 a year, or AED 4,500 more. If your rent were only 8% below the average, the cap would be zero.

To run the calculator, open the Dubai Land Department's rental index tool and enter the property type, the area or building, the unit size and your current annual rent. Use the same details as your Ejari contract so the comparison is like for like.

Check your lease first. Many commercial leases include a fixed annual escalation clause. Read it before you read the calculator, because what you signed is where any disagreement starts.

How much notice must a landlord give?

At least 90 days, in writing, before the lease expires. Dubai guides commonly cite Article 14 of Law No. 33 of 2008 for this rule. Al Tamimi notes that it applies to any change in terms for the renewal period, unless the parties have agreed otherwise in the lease.

If your lease ends on 31 December 2026, your landlord's notice of a new rent should reach you by early October. Notice that arrives late is on weak ground. Chambers and Partners says a non-compliant increase will generally not apply to that renewal, so you can stay on your existing terms.

If neither side says anything and you stay on, Al Tamimi reports that the lease renews on the same terms for a similar period or one year, whichever is shorter.

Can the landlord change chiller charges, cheques or other terms at renewal?

A landlord can propose changes, but the same 90-day notice applies to every term, not only rent. That includes the payment schedule, the number of cheques, chiller or cooling arrangements, and parking. A change you were never told about in time should not bind you at renewal.

Treat these changes as part of the rent conversation. A switch from a chiller-free office to one that charges for cooling raises your annual cost just as an increase in base rent does, even though the calculator will not show it. Ask for the full proposed terms in writing and compare total annual cost, not headline rent.

Can a commercial tenant be evicted at renewal?

Not on a whim. A landlord who wants to end a lease at expiry must give a legal reason and 12 months' notice. Under Article 25 of Law No. 26 of 2007 as amended, as summarised by Al Tamimi, the permitted reasons are:

• Demolishing the building for reconstruction, with the licences in place.
• Major renovation that cannot be done while you stay, certified by Dubai Municipality.
• Recovering the property for the owner's own use, or for a first-degree relative.
• Selling the property.

The notice must state the reason and be sent through a Notary Public or by registered mail. A normal email, or a short clause in your lease, does not replace it. If a dispute follows, the Rental Disputes Center can require the landlord to prove the reason.

This summary comes from a secondary source that predates recent updates, so ask a UAE lawyer to confirm how Article 25 applies to your premises before you act on it.

What to do if the increase looks too high

Start by negotiating with evidence and keep the Rental Disputes Center as the fallback. Most office renewals are settled between landlord and tenant. These steps give you the strongest position:

1. Check the notice. Confirm it is in writing, names the new rent and reached you at least 90 days before expiry.
2. Run the RERA calculator and save the result, together with your Ejari contract details.
3. Gather current asking rents for comparable offices in your tower and the neighbouring ones. Our Dubai office listings are a useful starting point.
4. Reply in writing before the lease ends, with your counter-offer and your evidence.
5. Trade terms, not only price. A longer commitment, a rent-free period or a staged increase can be worth more than a lower headline rent.
6. If talks stall, file at the Rental Disputes Center early, ideally before the new term starts. No source we checked sets a deadline, so ask a lawyer about timing.

If the numbers do not work, you can also compare alternatives. Moving costs fit-out, reinstatement and downtime, so weigh those against the increase before you decide.

How to file a case at the Rental Disputes Center and what it costs

You file online through the Rental Disputes Center portal and the fee for rent and renewal claims is 3.5% of the annual rent, between AED 500 and AED 20,000. The Rental Disputes Center offers two routes: an amicable settlement (conciliation) request, or a first-instance lawsuit. Registration takes one business day.

Documents you will need:

• Your latest Ejari contract.
• Your trade licence and the manager's or owner's ID if you are a company, or your Emirates ID if you are an individual.
• A bank letter or statement showing the IBAN for your claim.
• The landlord's notice, your replies and any related correspondence, in Arabic or legally translated.

You can register with your MyRDC login or through a Real Estate Services Trustee centre, which adds a partner fee of AED 130 plus VAT. Pay by Noqodi, card, or cash at a Real Estate Service Center.

On an office rent of AED 150,000 a year, the court fee would be AED 5,250. Law firms report that Dubai's conciliation department tries to settle first, and that judgments of AED 100,000 or more can be appealed to the Appeals Chamber. Fees were taken from the Rental Disputes Center service pages in November 2026, so check the portal before you file.

Frequently asked questions

Does the RERA rent calculator apply to offices?

Dubai's tenancy law covers commercial leases and Decree No. 43 of 2013 makes no exception for them. The Dubai Land Department calculator lists a commercial category, but sources differ on whether its result is a binding cap. Use it as your benchmark and confirm with the Dubai Land Department.

What is the maximum office rent increase at renewal?

The decree allows 0% to 20%, depending on how far your rent sits below the market average. If your rent is within 10% of the average, the cap is zero. If it is more than 40% below, the cap is 20%.

How much notice must the landlord give?

At least 90 days' written notice before the lease expires, for rent or any other change in terms.

Can my landlord change the chiller charges or cheque schedule at renewal?

They can propose it, but the same 90-day notice applies. Compare total annual cost, not only base rent.

Can my landlord refuse to renew my office lease?

Only for a legal reason, such as demolition, major renovation, owner's use or sale, and with 12 months' notice through a Notary Public or registered mail.

Can the landlord raise my rent during the lease term?

Not unilaterally. The rent in your signed lease holds for the fixed term unless both sides agree to change it. The decree's caps apply when the lease is renewed.

How much does it cost to file at the Rental Disputes Center?

3.5% of annual rent for rent, renewal and eviction claims, with a minimum of AED 500 and a maximum of AED 20,000, plus small administrative fees.

Plan your renewal before the notice arrives

The strongest position in a rent discussion belongs to the tenant who started early. Diarise 120 days before expiry, run the calculator, collect comparable rents and read your lease for escalation and cooling terms. Then you can respond to a notice in days, not weeks.

If you want an independent view of whether your office rent is in line with the market, or you are weighing a move, speak to CRC Property's commercial team.
