1. The price-per-m² trap: there is no single surface
We spontaneously compare two apartments by their price per square metre. The problem: this ratio makes no sense until you have stated, alongside the numerator, which surface exactly sits in the denominator. As we note in our guide on apartment valuation in Morocco, « a raw advertised price per m² tells you nothing. » And the first reason is mechanical: the surface is never unique.
For a single apartment, at least three readings coexist: the surface shown on the land title, the genuinely liveable living area, and the saleable(or weighted) area that developers and listings often use. The gap between these readings can be substantial — enough to entirely change the reading of the « right price ».
2. The three surfaces — and what each covers
- The land-title area. This is the legal reference: the one resulting from the land-registration document. It is what the expert checks first, because it is enforceable and documented — just like ownership itself, secured by the land-registration regime (Dahir of 12 August 1913). Any gap with what is measured on site is a warning sign to investigate.
- The living area. These are the enclosed, covered, genuinely liveable spaces: rooms, circulation areas, excluding outdoor surfaces (balconies, terraces) and common parts. It is the most « honest » reading of what you actually live in.
- The saleable / weighted area. This is a commercial surface that reintegrates outdoor surfaces, using coefficients, and sometimes a share of common parts. It is often the basis for a developer's advertised price. As we flag in the apartment appraisal guide, the gap between usable area and saleable area can reach 12 to 18% on some new-build schemes.
Direct consequence: an apartment « 100 m² at such a price » may be 100 m² saleable (with balconies and weighted commons) or 100 m² of living area. At an identical total price, the price per m² actually lived in is not the same — and that is the whole point of the purchase decision.
3. Why listings diverge so much
The divergence is not (always) bad faith: it is mostly a failure to define. Very few listings state the measurement basis of the surface they display. Several sources collide:
- The developer's original commercial sheet, in saleable area.
- The land title, reused by some cautious sellers.
- A visual estimate or a rounded figure « from memory » on older stock.
- A usable area measured by an agent, closer to the living area.
The result: for a single property, surfaces differing by several square metres can circulate, without any being « false » — they simply do not describe the same thing. The only way to settle it is to cross-check: land title, plan, and adversarial on-site measurement. This is precisely the first step of the comparison method applied to an apartment, where the surface adopted is explicitly the land-title one.
4. Treating balconies, loggias and terraces: the weighting
A 10 m² balcony is not « worth » a 10 m² living room. That is the very intuition behind the weighted area: outdoor surfaces are assigned a coefficient below 1 to reflect their lower utility compared with a covered, enclosed living area. The logic is consistent with the comparison method (VPS 3 of the RICS Red Book), which adjusts each gap between the property and its comparables.
The coefficient is not a universal scale: it depends on the local market, the aspect, the size of the annex and its actual use (a large, usable terrace on a sunny top floor is not treated like a 2 m² corridor-balcony). The expert documents the coefficient adopted rather than applying it mechanically — this is what distinguishes a defensible pricing from a hasty multiplication.
- Covered, enclosed living area: full value (reference coefficient).
- Balcony, loggia, terrace: downward weighting, variable by utility and aspect.
- Cellar, storeroom, parking space, box: valued separately, not « merged » into the living-area price per m².
5. And the common parts? The share that inflates (or not) the price
In condominium, each apartment is a lot assigned a share of the common parts (stairwell, lobby, technical room, etc.). The living area does not include these commons — but some saleable areas reintegrate a fraction of them. Hence gaps that surprise buyers.
The expert's role is to clearly distinguish the private usable area from the share of commons, so as not to compare a « private » price per m² of one property with a « commons-included » price per m² of another. Without this discipline, you compare apples and oranges — and the apparent price gap is just a measurement artefact. To understand how these elements fit into a rigorous estimation approach, see our guide on estimation methods and their reliability.
6. How the expert settles it: cross-checking and measurement
Faced with divergent surfaces, an expert does not « pick » the most flattering one: they cross-check and document. The approach, compliant with RICS standards and adapted to the Moroccan land context:
- Verification of the land title and the plan: the legal anchor of the surface.
- On-site measurement (adversarial survey), to confront reality with the document.
- Identification of the basis of each comparable: only surfaces defined the same way are compared.
- Explicit weighting of annexes (balconies, terraces) and separate treatment of parking and cellar.
- Statement of the basis adopted in the report: « value established on a surface of X m² per the land title », to remove any ambiguity.
It is precisely this level of detail that makes the difference between an approximate opinion and a report compliant with RICS (Red Book) standards — useful to support your position with third parties in a negotiation, usable by a bank, and defensible in the face of a challenge. For the boundary between these two deliverables, see professional appraisal vs free estimate.
7. The right reflex before buying (or selling)
- Demand the measurement basis. Before discussing the price, ask: « this surface, is it land title, living area or saleable? » The answer changes everything.
- Cross-check against the land title. It is the only surface backed by an enforceable document. An unexplained gap warrants a check.
- Have the annexes weighted. Balconies and terraces are not counted like a living room: an expert values them at their fair utility.
- Think about separate annexes. Parking, box and cellar have their own value — to be isolated, not diluted into the price per m².
- For a remote purchase (non-residents in particular), have the property measured and cross-checked on site: it is the number-one risk item when you have not seen the property.
8. FAQ
Which surface area really counts in an apartment's price in Morocco?
There is no single surface: the land-title area (legal reference), the living area (enclosed, covered, liveable spaces) and the saleable or weighted area (which reintegrates balconies, terraces and a share of commons using coefficients). A price per m² only makes sense once you state which surface it is calculated on.
Why does the advertised surface differ from the land-title one?
Because listings rarely state their measurement basis: some reuse the developer's saleable area, others the living area, others a rough rounded figure. The land-title area comes from the registration document. The expert systematically cross-checks these sources before any pricing.
How does the expert treat a balcony or a terrace in the price?
They apply a weighting: a coefficient below 1 assigned to outdoor surfaces to reflect their lower utility compared with a covered, enclosed living area, in line with the comparison method (VPS 3 of the RICS Red Book). The coefficient depends on the local market, the aspect and the actual use.
Do common parts count in an apartment's surface?
The living area does not include them. In condominium, each lot is assigned a share of the common parts, and some saleable areas advertised by developers reintegrate a fraction of them. The expert distinguishes the private usable area from the share of commons so as not to artificially inflate the price per m².
Should you have the surface checked before buying an apartment in Morocco?
It is strongly recommended, especially for a remote purchase or an older property. A surface gap directly changes the real price per m² and the relevance of the asking price. An independent appraisal report prepared by RICS-certified experts cross-checks the land title, on-site measurement and comparables: report within 5 to 8 days (48-72 h express), firm quote within 24 h, from 3,500 MAD excl. tax.
Unsure about the real surface of your apartment?
RICS-certified experts — land-title cross-checking, on-site measurement, weighting of annexes and documented comparables. Reports compliant with the Red Book, anywhere in Morocco, within 5 to 8 days (48-72 h express). From 3,500 MAD excl. tax.
Note: This article describes a method for analysing surface area; the weighting coefficients and gaps cited are indicative and depend on the local market, the condition and the configuration of the property. For the legally enforceable surface, refer to the land title and confirm with your notary. To have the real surface and value of your property established, see our real estate appraisal page or the real estate blog.
