Buying off-plan means agreeing to purchase an apartment before you can physically measure the finished space.

That creates an obvious question:

What happens if the apartment delivered at handover is smaller than the one described in the Sale and Purchase Agreement?

Dubai's property framework specifically addresses this issue.

Dubai Land Department states that where the completed property's area is less than the area agreed in the sale contract, the developer must compensate the purchaser where the decrease exceeds 5% of the unit's net area.

The underlying legislation also states that the SPA and unit plan provide the basis for calculating the difference.

This makes the area written into your contract much more important than a number shown in a marketing advertisement.

Start With the Contracted Area

Before worrying about the 5% rule, identify which area the contract actually uses.

A property advertisement may show a headline size.

A floor plan may show another figure.

The SPA should identify the contractual area relevant to the sale.

Dubai's legislation says the net area of the unit is used for registration and that the net area stated in the sale agreement and unit plan is the basis for calculating any shortage or excess.

So the buyer should retain:

• final SPA;

• signed floor plan;

• unit schedule;

• any approved revisions;

• provisional registration documents.

Do not rely on an old screenshot from the original sales launch.

What Does the 5% Rule Mean?

Suppose the contracted net area is 1,000 square feet.

Five percent of 1,000 square feet is 50 square feet.

The DLD rule becomes relevant when the decrease in net area exceeds that 5% threshold.

The rule should not be simplified into:

“Any difference under 5% means everything is automatically fine.”

Other contractual or factual issues may still matter.

The key point is that Dubai's legislation creates a specific compensation requirement where the shortage goes beyond 5% of the agreed net area.

How Is Compensation Calculated?

The implementing legislation states that where the shortage exceeds the prescribed 5% threshold, the compensation payable to the purchaser is calculated based on the unit price agreed in the relevant contract.

That means the buyer should not invent a compensation figure using current market prices.

The contractual purchase price is the relevant reference under the rule.

If a meaningful discrepancy appears, request the calculation in writing.

For a valuable property, the exact interpretation should be confirmed against the SPA and official/legal guidance rather than relying on an informal estimate.

What If the Apartment Is Larger?

The rule also addresses the opposite situation.

DLD states that when the completed unit's net area exceeds the area agreed in the sale contract, the extra area generally is not taken into account and the developer cannot claim additional payment unless the contract expressly provides otherwise.

The underlying legislation says the same: unless otherwise agreed, the developer may not claim the value of the additional net area.

This is another reason to read the SPA carefully.

The contract can matter when extra area is delivered.

Why This Matters More for Off-Plan Buyers

Someone purchasing off-plan apartments in Dubai is buying a future physical asset based heavily on documents.

The buyer cannot walk into the completed unit and measure it before signing.

That makes the following documents especially important:

• SPA;

• floor plan;

• unit specifications;

• area schedule;

• approved amendments.

The stronger your records, the easier it is to identify what was originally agreed.

Net Area vs “Total” or Marketing Area

This is where buyers can become confused.

Different property materials may refer to:

• internal area;

• balcony area;

• total unit area;

• gross area;

• net area.

Do not assume these terms are interchangeable.

The Dubai rule specifically refers to the unit's net area for the calculation.

If the marketing brochure highlights a larger “total area” but the SPA uses a clearly defined net area, the contractual figure is more important when assessing the legal shortage rule.

Ask the salesperson to explain the breakdown before you sign.

What Should You Do Before Handover?

When the project approaches completion, retrieve your original documents.

Do not arrive at handover relying on memory.

Prepare:

The SPA
Check the stated unit and net area.

The signed floor plan
Compare the configuration with the completed apartment.

Any developer notices
Look for approved revisions issued during construction.

Your provisional registration records
Make sure the unit details remain consistent.

This gives you a baseline before the inspection begins.

Should You Measure the Property?

If the final area appears materially different from the contractual documents, obtain reliable evidence.

For a serious discrepancy, a professional measurement may be appropriate.

Do not base a formal complaint on visual impressions such as:

“The living room feels smaller.”

Furniture, ceiling height, wall thickness and layout can change how a room feels.

The issue is the measured net area compared with the contractual net area.

What If the Title Deed Area Differs From the Initial Record?

DLD's current FAQ addresses this situation too.

Where there is a difference between the area registered initially and the area on the issued title deed, DLD advises verifying the contract area and registered area, comparing them with engineering drawings where available, and referring the investor to its Legal Affairs Department for advice.

That is a useful reminder:

The correct next step is evidence and verification—not immediately assuming fraud or accepting the discrepancy without question.

What About Layout Changes?

Area is only one part of what was promised.

A developer might deliver approximately the expected square footage but change:

• room proportions;

• door positions;

• kitchen arrangement;

• balcony configuration;

• storage;

• internal walls.

Whether a particular revision is permitted depends on the SPA, approved project documents and circumstances.

The 5% area rule should not be treated as a blanket rule allowing every other change.

If a material layout or specification change affects the value or use of the property, review the contract and obtain appropriate advice.

Keep Marketing Material, But Know Its Limits

Brochures, renders and advertisements can be useful evidence of how a project was promoted.

However, they may contain disclaimers explaining that images are illustrative.

Your strongest documents are generally the contractual documents and approved unit plans.

That does not mean marketing information is irrelevant.

It means a buyer should know the difference between:

sales presentation

and

contractual promise.

What If You Disagree With the Developer?

Dubai's implementing legislation provides that DLD may attempt conciliation where a dispute arises between developer and purchaser, with any agreed settlement documented in writing and becoming binding once confirmed by the Department.

Depending on the dispute, further legal remedies may also be relevant.

For a substantial area discrepancy, keep communication factual.

State:

• contracted net area;

• final measured/registered net area;

• percentage difference;

• SPA clause;

• requested remedy.

Avoid relying only on verbal conversations.

A Simple Example

Assume an SPA states a net unit area of 1,200 sq ft.

A later official measurement shows 1,125 sq ft.

The shortage is 75 sq ft.

75 ÷ 1,200 = 6.25%.

Because the shortage exceeds 5%, the DLD compensation rule becomes relevant.

The actual compensation calculation should then follow the contractual price framework set out in the legislation.

This simple calculation helps buyers identify when they should investigate further.

The Buyer Checklist

Before purchasing off-plan:

1. Confirm the exact net area in the SPA.

2. Keep the signed unit plan.

3. Do not rely solely on brochure measurements.

4. Save every approved revision.

5. Compare final documentation at handover.

6. Investigate any material discrepancy promptly.

7. Put questions and responses in writing.

The Bottom Line

Dubai does not leave the issue of off-plan area differences completely undefined.

DLD states that if the completed property is smaller than the contractual area, the developer must compensate the purchaser where the decrease exceeds 5% of the unit's net area.

The legislation further provides that the sale agreement and unit plan are the basis for the calculation, and compensation is tied to the agreed unit price.

For an international buyer, the practical lesson is straightforward:

Know exactly what area you contracted to buy before construction begins.

If you understand the SPA and keep the original unit documents, you are in a much stronger position to compare what was promised with what is eventually handed over.
