RERA Rental Index Dubai 2026: Rent Increase Rules

If you rent, own or manage property in Dubai, the single number that decides your next renewal is not what your landlord thinks the flat is worth. It is the benchmark produced by the RERA rental index — the Dubai Land Department and Real Estate Regulatory Agency tool, now branded the Smart Rental Index, that estimates the average market rent for your specific building, community, unit type and size. That benchmark then feeds a fixed formula: if your contract rent sits within 10% of the average, your landlord may not increase it at all, and the maximum lawful increase in any circumstance is 20%.

That formula is not negotiable, not a guideline and not a starting point for haggling. It comes from Decree No. 43 of 2013, and it has held steady while Dubai's rental market has moved through several cycles. Understanding it protects tenants from unlawful hikes, protects landlords from losing a whole year of income to a missed notice deadline, and protects anyone building a property management or brokerage business from a compliance failure that costs far more than the rent in dispute. This guide walks through the index, the slabs, the notice rules, the dispute route, the tax and licensing layer, and a worked example in AED.

What Is the RERA Rental Index and How Does It Work in 2026?

The RERA rental index is Dubai's official rent benchmark. It estimates the average market rent for your building, area, unit type and size, then caps renewal increases under Decree No. 43 of 2013: 0% if your rent is within 10% of the average, rising through 5%, 10% and 15% to a hard ceiling of 20% when rent sits more than 40% below the benchmark. Landlords must give 90 days' written notice.

The index is not a valuation of your individual apartment. It is a statistical average built from registered tenancy data — which is precisely why Ejari registration matters so much. Every contract registered through Ejari feeds the dataset. Unregistered side agreements do not, which means a building with poor registration discipline produces a weaker benchmark for everyone in it.

Read the table carefully, because the most common misunderstanding in Dubai renewals is hidden in it. The percentage in the middle column is applied to your current contract rent, not to the index average. A tenant paying AED 55,000 against a benchmark of AED 100,000 does not jump to AED 100,000. They move to AED 66,000. The gap closes gradually, over successive renewals, which is exactly what the decree was designed to achieve — a market that adjusts without displacing households in a single step.

The index itself is published and maintained under the Dubai Land Department umbrella at https://dubailand.gov.ae/, with a rental increase calculator that any tenant or landlord can run for free. You enter the emirate area, the property type, the number of bedrooms, the built-up area where relevant, and your current annual rent. The calculator returns the applicable average and the permitted increase percentage. It takes under two minutes and it is the single most useful piece of evidence either party can bring to a renewal conversation.

Who the RERA Rental Index Applies To — and What Sits Outside It

The index and the Decree 43 slabs apply broadly across Dubai's leasing market, not only to apartments. The categories benchmarked include:

• Residential units — studios, one-bed to five-bed apartments, townhouses, villas and compound villas, segmented by community and often by individual building or cluster.
• Commercial units — offices, retail shops, showrooms and mixed-use ground-floor space, benchmarked by area and by square-foot rates in many districts.
• Industrial units — warehouses, workshops and light industrial plots in areas such as Al Quoz, Dubai Investments Park and the Ras Al Khor industrial belt.
• Staff accommodation — labour accommodation buildings and shared units, benchmarked separately from standard residential stock.

There are meaningful exclusions and edge cases. Short-term holiday-home lettings licensed by the Department of Economy and Tourism operate on a different commercial model — nightly or weekly rates set by the operator — and are not governed by annual renewal caps in the way a twelve-month tenancy is. If you are converting a residential unit into a holiday home, you leave the Decree 43 world and enter the DET permit world, with its own registration, classification and tourism-fee obligations.

Free zone properties can also behave differently. Some free zone authorities administer their own leasing frameworks for units inside their jurisdiction, and a lease signed directly with a free zone authority as landlord may sit under that authority's rules rather than the standard Dubai tenancy regime. Where a free zone unit is owned by a private landlord and leased on a standard Dubai contract, the usual rules generally apply. If you are unsure which regime governs your unit, the safest route is to check whether the tenancy is registered through Ejari — that registration is a strong signal of which framework you sit in.

New buildings present a third edge case. A property that has never been let has no historic registered rent for that unit, so the first contract is freely negotiated between landlord and tenant. The index only bites at renewal, when there is an existing contract rent to compare against a benchmark. This is why some landlords price aggressively on the very first lease of a new tower: that opening figure sets the baseline they will be measured from for years afterwards.

Decree No. 43 of 2013: The Five Slabs in Detail

The decree replaced an earlier flat-cap approach with a graduated model, and the logic is worth understanding rather than memorising.

Slab one — within 10% of the average: no increase. If your contract rent is at, above, or up to 10% below the index average, your landlord has no legal right to increase it at renewal. This is the slab most Dubai tenants fall into after a couple of years of stable occupancy, and it is the reason so many renewal notices quietly disappear once a tenant produces a calculator printout.

Slab two — 11% to 20% below: maximum 5%. A modest correction. On a rent of AED 90,000 sitting 15% below benchmark, the landlord may add AED 4,500.

Slab three — 21% to 30% below: maximum 10%. This is where long-tenured tenants in fast-appreciating communities typically land. A tenant who signed in a soft market and stayed through a strong one will drift into this band naturally.

Slab four — 31% to 40% below: maximum 15%. Increasingly common in communities that have seen rapid infrastructure delivery — new metro links, new schools, new retail anchors — where market rents have re-rated faster than sitting tenancies.

Slab five — more than 40% below: maximum 20%. The absolute ceiling. No matter how far below market a rent has fallen, 20% is the most that can be applied in a single renewal cycle. A tenancy sitting 60% below benchmark still moves only 20% this year.

Two practical points follow. First, the slab is determined by the gap, and the gap is measured against the index average at the time notice is given. If the market moves between notice and renewal, the notice does not automatically update. Second, the landlord may always apply less than the maximum. The slab is a ceiling, not an entitlement, and a landlord who values a reliable tenant frequently applies nothing at all even when entitled to 10%.

The 90-Day Notice Rule: The Deadline That Decides Everything

If there is one rule that costs Dubai landlords more money than any other, it is this one. Under UAE tenancy law as applied in Dubai, a landlord who wishes to change any term of the tenancy at renewal — the rent, the number of cheques, the payment schedule, the inclusion of maintenance, anything — must notify the tenant in writing at least 90 days before the contract expiry date, unless the parties have agreed a different notice period in writing within the contract itself.

Miss the ninety days and the contract renews automatically on identical terms for a further year. Not on partially amended terms. Identical. The landlord who sends a rent-increase notice sixty days out has, in practice, given the tenant a free year at the old rate.

The same discipline binds tenants. A tenant who wants to change terms — reduce the rent to match a falling index, split into more cheques, add a car park — must also give ninety days' notice. Many tenants do not realise this and only raise the conversation thirty days out, by which point the contract has locked.

Notice should be served in a form that can be evidenced later. Practical options include registered post, courier with proof of delivery, notarised notice through a notary public, or email where the tenancy contract explicitly nominates email as a valid service channel. A verbal conversation in the lobby, a message on a chat app to an unverified number, or a note slipped under a door are all reasons a case falls apart at the Rental Disputes Centre. Keep the delivery receipt with the tenancy file — it is the evidence, not the notice itself, that wins the argument.

How the Building Quality Star Rating Feeds Into the Smart Rental Index

The most significant recent evolution of the index is the addition of a building classification or star rating layer. The older model benchmarked largely by area and unit type, which produced an obvious unfairness: a well-maintained, recently handed-over tower with working lifts, a functioning gym, professional facilities management and clean common areas was benchmarked against a tired building on the same street with none of those things. Both sat in the same "one-bedroom in this community" bucket.

The Smart Rental Index addresses this by scoring buildings on quality attributes and letting that score shift the applicable benchmark. Broad factors that feed a building's rating include:

• Age and condition of the structure, including facade, common areas and structural maintenance history.
• Quality and reliability of facilities management, including responsiveness to maintenance requests and the state of lifts, lighting and corridors.
• Amenities provided — pool, gym, covered parking, children's play areas, retail on the ground floor.
• Utility and services infrastructure, including chiller arrangements, DEWA connectivity and metering setup, and waste management standards.
• Compliance record with Dubai Municipality requirements on building safety, cleanliness, pest control and signage, and with Civil Defence fire-safety systems.

The practical consequence for landlords is direct: maintenance is now a revenue lever, not just a cost line. A landlord who invests in facade cleaning, lift refurbishment and a competent facilities management contract can see the building's benchmark rise, which in turn widens the gap between sitting rents and the index average, which in turn permits larger lawful increases at renewal. A landlord who defers maintenance for five years sees the opposite.

For tenants, the rating gives a concrete lever in renewal conversations. If a landlord claims the benchmark supports a 15% increase but the building has had a broken lift for four months and a chronically unresponsive management company, that is a documented argument to bring to the Rental Disputes Centre — supported by dated maintenance tickets and photographs.

Why Ejari Registration Makes a Tenancy Visible to the Index

Ejari is the tenancy registration system that turns a private contract between two parties into a recognised, indexed, enforceable record. Its role in this whole framework is structural rather than administrative.

First, Ejari registration is what feeds the dataset the index is built from. Every registered contract contributes a data point on what a real unit of that type in that building actually rented for. The index is only as accurate as the registrations behind it. Buildings where landlords routinely skip registration produce thin, unreliable benchmarks — which usually hurts the landlords in that building more than the tenants, because a weak benchmark undermines any future increase claim.

Second, Ejari is the gateway to almost everything else a tenant needs. A DEWA connection in the tenant's name, a residence visa application processed for family members, a school registration under KHDA-regulated admissions, a trade licence issued against a residential address in permitted cases, telecom connections and municipality fee assessments all lean on a registered tenancy. Without it, a tenant is functionally invisible to the city's administrative systems.

Third, and most relevant here, the Rental Disputes Centre will normally expect a registered tenancy before it will hear a case. A tenant who has been paying rent for three years on an unregistered contract and then receives a 40% increase demand is in a materially weaker position than one who registered on day one. Registration is cheap insurance; the fee is a small fraction of a single month's rent for most units.

For anyone running property as a business — a portfolio landlord, a property management company, a brokerage handling leasing — Ejari registration discipline should be a hard operational rule, tracked in a system, with renewal registrations diarised alongside the 90-day notice deadline. If you are building that operation from scratch, our guide to Ejari registration in Dubai walks through the mechanics end to end.

Step-by-Step: How a Landlord Lawfully Raises Rent

Step 1 — Diary the deadline. Work backwards from the contract expiry date and mark the day 90 days before it. For a contract expiring 31 December, notice must be served by 2 October at the latest. Serve earlier if you can; there is no penalty for giving 120 days.

Step 2 — Run the calculator. Use the official rental increase calculator on the Dubai Land Department portal. Enter the area, property type, bedroom count, built-up area and current annual rent exactly as they appear on the registered Ejari contract. Save or screenshot the result with the date visible.

Step 3 — Identify your slab and calculate in AED. Convert the permitted percentage into a specific dirham figure applied to the current contract rent. Do not present a percentage alone; present the new annual rent.

Step 4 — Draft the notice. It should state the tenant's name, the unit, the existing contract expiry date, the proposed new rent in AED, any other changed terms such as cheque count, the date of the notice, and a clear statement that the change takes effect from the renewal date.

Step 5 — Serve it provably. Notary public, registered post or courier with tracked delivery. Retain the proof.

Step 6 — Negotiate in good faith. Many landlords apply less than the maximum for a tenant with a clean payment record. A vacant unit for two months costs more than the increase you were arguing over.

Step 7 — Issue the renewal contract and re-register. Once terms are agreed, issue the new tenancy contract and renew the Ejari registration. Update the utility arrangements where the cheque structure or the responsible party changes.

Step 8 — Keep the file. Notice, proof of service, calculator printout, signed contract, Ejari certificate. If a dispute arises two years later, this file is your case.

Step-by-Step: How a Tenant Challenges an Unlawful Increase

Step 1 — Check the notice date first, not the amount. If notice arrived fewer than 90 days before expiry, the increase is not enforceable regardless of whether the percentage was correct. This single check resolves a large share of disputes before they start.

Step 2 — Run the calculator yourself. Do not rely on the landlord's figure. Enter your own details and generate your own printout with a visible date.

Step 3 — Reply in writing, calmly. Attach your calculator result, state the permitted increase in AED, and propose the lawful renewal figure. Most landlords, particularly those working through a professional property manager, will correct course at this point. A polite written exchange resolves the overwhelming majority of cases.

Step 4 — Escalate to the Rental Disputes Centre if needed. The Rental Disputes Centre is the judicial body handling Dubai tenancy matters. You will typically need the tenancy contract, the Ejari certificate, proof of rent payments, the landlord's notice, your written reply, and the index calculation. Filing fees are commonly assessed as a percentage of the annual rent, subject to a minimum and maximum, so budget for them rather than being surprised.

Step 5 — Keep paying rent. A tenant who withholds rent during a dispute converts a strong case about an unlawful increase into a weak case about non-payment. Pay at the existing lawful rate while the matter is heard.

Step 6 — Comply with the outcome. Decisions are enforceable. Where an increase is found unlawful, the renewal proceeds at the lawful figure; where it is upheld, the tenant pays the difference.

Eviction Notices: The 12-Month Notarised Rule

Rent increases and evictions are separate mechanisms, and conflating them is a frequent and expensive error. A landlord who wants to recover the property for sale, for personal use, for use by a first-degree relative, or for comprehensive demolition and reconstruction must serve a 12-month written notice through a notary public or by registered post, stating the specific reason.

Key features of the rule at a high level:

• The notice period is twelve months, not ninety days. The 90-day rule governs changes to terms; the 12-month rule governs recovery of possession.
• The notice must be notarised or sent by registered post. Informal service does not satisfy the requirement.
• The reason must be stated and must fall within the grounds recognised in law. A generic "we want the unit back" is not sufficient.
• Notice for these grounds is generally served to take effect at or after the end of the current term, not to terminate a live contract mid-term.
• Separate, shorter routes exist for tenant breach — non-payment, illegal use, unauthorised subletting, structural alteration without consent — and those follow their own procedure.

A landlord who serves a valid 12-month notice for personal use and then re-lets the unit to a third party shortly afterwards exposes themselves to a compensation claim from the former tenant. Treat the stated reason as a commitment, not a formality.

Worked Example: Contract Rent, Index Average and Permitted Increase in AED

The table below applies the Decree 43 slabs to five realistic renewal scenarios across different unit types. All figures are illustrative arithmetic derived from the fixed statutory percentages.

Two observations from the table are worth internalising.

The three-bedroom townhouse tenant is paying AED 130,000 against a benchmark of AED 200,000 — a gap of AED 70,000. The permitted increase closes only AED 19,500 of it. Even at the maximum slab every year, it would take several renewal cycles to converge, and by then the benchmark itself will have moved. This gradualism is a feature of the framework, and it is why long-tenured Dubai tenants often enjoy materially below-market rents for years.

The retail unit sits in the top slab, and note that the AED 22,000 increase is calculated on the AED 110,000 contract rent, not on the AED 200,000 benchmark. If it were calculated on the benchmark it would be AED 40,000. Getting this base wrong is the single most common arithmetic error in Dubai renewal notices.

Running Property as a Business: Tax, Licensing and Compliance

The moment property ownership stops being a passive personal holding and starts being an operating business — multiple units, active management, letting services for others, holiday-home operation — a second layer of obligations opens up.

Corporate tax. The UAE corporate tax regime applies 0% on taxable income up to AED 375,000 and 9% above that threshold. Registration is handled by the Federal Tax Authority through the EmaraTax platform at https://tax.gov.ae/, and the return is due nine months after the end of the financial year. The treatment of real estate income depends heavily on structure: income earned by a juridical person conducting a property business is within scope, whereas certain real estate investment income earned by a natural person in a personal capacity, without a licence, is commonly treated as outside the regime. Because the distinction turns on facts, confirm your specific position with the Federal Tax Authority or a qualified tax adviser rather than assuming.

VAT. The UAE applies VAT at 5%, with a mandatory registration threshold of AED 375,000 in taxable supplies and a voluntary threshold of AED 187,500. The real estate treatment splits cleanly in most cases: commercial rent is generally subject to VAT at 5%, while residential leases are generally exempt. A landlord with a mixed portfolio therefore has a mixed VAT profile, with input-recovery consequences that are easy to get wrong. Holiday-home and serviced-apartment income typically behaves differently again, since short-term accommodation is not treated the same way as a residential lease.

Licensing. A company that manages property for third parties, brokers leases, or operates units commercially needs a licence from the Department of Economy and Tourism with the appropriate activity attached — property management, real estate brokerage, or holiday-home operation each map to distinct activity codes. Brokerage and property management activities additionally require RERA registration and broker certification for the individuals involved. Holiday-home operators need a specific DET permit per unit, with classification, tourism-fee collection and guest-registration obligations attached.

Municipality and building compliance. Dubai Municipality governs building safety, signage approvals, waste management, pest control and fit-out permissions. A property management business handling common areas and maintenance inherits these obligations in practice, and inspection findings can affect a building's quality rating — which loops directly back into its position on the Smart Rental Index.

Housing fee. Dubai levies a municipality housing fee on residential tenancies, commonly collected through the DEWA bill and calculated as a percentage of the annual rent stated on the registered Ejari contract. Tenants are frequently surprised by it because it arrives monthly rather than annually. Landlords should flag it during renewal discussions so the tenant budgets for the true occupancy cost rather than the headline rent.

If you are formalising a portfolio into a licensed operation, our guides to starting a real estate business in Dubai and to business setup in Dubai cover the structure, activity and licensing decisions in sequence.

DEWA and Utility Transfers at Renewal

Utilities are the quiet failure point of Dubai renewals. DEWA accounts are tied to the premises and to the account holder, and the account holder is normally the tenant on the registered Ejari contract.

At renewal, three scenarios recur:

Renewal with the same tenant. The DEWA account usually continues without interruption, but the registered Ejari contract details should be updated so the housing fee is assessed on the new annual rent rather than the old one. Landlords who raise rent but never update Ejari create a mismatch that surfaces later.

Change of tenant. The outgoing tenant applies to close the account, settles the final bill, and receives the security deposit refund. The incoming tenant opens a new account against the new Ejari certificate and pays a fresh deposit. Between the two, there is a window where the unit is on the landlord's account — worth managing deliberately, because a unit sitting on an open account through a Dubai August accrues meaningful cooling cost.

Chiller and district cooling. Many Dubai buildings run district cooling on a separate provider account, distinct from DEWA. Whether the landlord or tenant carries the chiller capacity charge should be stated explicitly in the tenancy contract, because it materially changes the effective cost of the unit and is a frequent source of dispute at renewal.

A practical rule for landlords and property managers: build a renewal checklist that runs the index calculation, serves the 90-day notice, issues the contract, renews Ejari, updates the housing fee basis, confirms the DEWA account status and confirms the chiller arrangement. Six items, one checklist, and the majority of renewal disputes never occur.

Common Mistakes with the RERA Rental Index

• Applying the percentage to the index average instead of the contract rent. A 20% slab on a rent of AED 55,000 is AED 11,000, not AED 20,000 on a AED 100,000 benchmark. This error inflates notices and gets them struck down.
• Serving notice inside 90 days. A perfectly calculated increase served 60 days before expiry is unenforceable. The contract renews on identical terms and the landlord loses the year.
• Skipping Ejari registration. An unregistered tenancy is invisible to the index, weakens the landlord's position at the Rental Disputes Centre, and blocks the tenant from DEWA connections and dependent visa processing.
• Assuming the maximum slab is an entitlement. It is a ceiling. Losing a reliable tenant to a vacancy of two or three months routinely costs more than the increase being pursued.
• Confusing the 90-day term-change notice with the 12-month eviction notice. They are separate mechanisms with separate service requirements, and using one where the other is required invalidates the action.
• Comparing against the wrong unit type. A benchmark for a one-bedroom in the same community does not apply to your two-bedroom, and a benchmark for a serviced building does not apply to a non-serviced one. Enter the exact unit specification.
• Ignoring the building quality rating. Landlords who defer maintenance depress their own benchmark; tenants who never document broken lifts and unresponsive facilities management lose a genuine argument at renewal.
• Overlooking tax and licensing once the portfolio scales. Managing property for others, or operating holiday homes, requires DET licensing and RERA registration, and the Federal Tax Authority thresholds of AED 375,000 for corporate tax and VAT registration arrive faster than most landlords expect.

Get Your Dubai Property Business Set Up Right with Noble Core

The rental index is a compliance framework, but for anyone operating property at scale it is also a commercial model. The landlords who do best in Dubai are not the ones who push the hardest at renewal — they are the ones who register every tenancy, diary every notice, maintain the building so its benchmark rises, and structure the operation so the tax and licensing layer is handled before it becomes a problem.

Noble Core Ventures works with founders and portfolio owners on exactly that transition: choosing between mainland and free zone structures, attaching the right DET activity for property management, brokerage or holiday-home operation, handling RERA registration requirements, getting Ejari processes running as a repeatable system, and aligning with Federal Tax Authority corporate tax and VAT obligations from the outset rather than retrospectively.
