Valuing a ground-floor retail unit in Morocco: the complete method

1. Why a retail unit is not valued like an apartment

For a home, the living area and the quality of the property explain most of the value. For a retail unit, the logic is reversed: it is the location and the ability to generate turnover that come first, well before the gross floor area. The same square metre can be worth three times more depending on whether it faces a busy artery or a quiet street fifty metres away.

Practical consequence: applying an "average neighbourhood" price per m² to a retail unit is the most frequent — and the most costly — mistake. The value is built through a hierarchy of criteria and, most often, through the combination of two approaches: direct comparison and capitalisation of rental value. This is precisely the approach of a valuation compliant with RICS standards, as for a mixed-use building.

2. The hierarchy of value criteria

Not all criteria carry the same weight. In decreasing order of importance for a ground-floor unit:

• The location (no.1 / 1bis / 2). Prime location no.1 is the best commercial position on an artery: maximum pedestrian flow, visibility, proximity to attractive brands. 1bis denotes a very good position just off-prime; no.2, a decent but secondary location. The value gap between a no.1 and a no.2 on the same street is considerable.
• The frontage length and visibility. The wider the street frontage, the more commercially powerful the unit: extended shop window, visible signage, easy access. A corner unit, exposed on two streets, benefits from a significant visibility premium. For an equal area, a unit "all frontage" is worth markedly more than a unit "all depth".
• The depth and configuration. Beyond a certain depth, the square metres at the back become hard to use (storage, sanitary facilities) and lose value. A regular shape, a generous ceiling height and the absence of obstructive pillars all count.
• The complementary area (mezzanine, basement). Mezzanine and basement add area, but at a reduced value: they are not first-rank sales areas.
• The authorised use. The condominium bylaws and planning rules can restrict certain activities. A unit free of any restriction is worth more than a constrained one.
• The rental situation. Vacant or occupied, the level of in-place rent, the tenant's status: decisive for an investor-buyer (see section 5).

3. Weighted area: never crudely add up the m²

Comparing two units on their total area alone makes no sense, because not all square metres are equal. The expert reduces heterogeneous areas to a weighted retail area, assigning each zone a coefficient according to its commercial use value:

• Shop-window and frontage zone: the highest coefficient — this is the first-rank sales area.
• Depth and back-of-shop: a decreasing coefficient as you move away from the street.
• Mezzanine: a reduced coefficient, modulated by accessibility (visible staircase or not) and actual use (sales, storage, office).
• Basement and storage: an even lower coefficient, depending on access and usability.

The coefficients are not fixed by a universal schedule: they fall within the expert's professional judgement, justified in the report. This weighting then allows units of very different configurations to be compared on a consistent basis — a principle also found in the RICS comparison method applied to residential property.

4. Two complementary approaches: direct comparison and capitalisation

Once the weighted area and qualitative criteria are established, two main methods lead to the value. They are not mutually exclusive: a serious valuation cross-checks them.

Direct comparison (the market approach). This relies on recent transactions of comparable units — same type of artery, similar location, close configuration — adjusted for the differences (frontage, depth, use). It is the natural approach for a vacant unit, intended to be occupied by its buyer or re-let at the market price.

Capitalisation of rental value (the income approach). This starts from the unit's net market rent and applies a capitalisation rate representative of the segment and the risk. The value follows the formula: value = net annual income ÷ capitalisation rate. It is the approach required for an occupied unit or one bought as an income investment, where the buyer thinks in terms of yield. The choice of rate is decisive: its orders of magnitude, its ranges by segment and the factors that move it are detailed in our guide to the cap rate in commercial real estate.

5. Occupied unit: the impact of a 49-16 lease and lease rights

The rental situation can change everything. A unit occupied by a retailer holding a lease subject to law 49-16 (the law on leases for commercial, industrial or craft use, of 18 August 2016) benefits from a protective status: a right of renewal and, if renewal is refused, an eviction indemnity in the tenant's favour. For the buyer, this means they will not freely recover the unit.

Two parameters then weigh on the value:

• The in-place rent relative to the market rent. If the contractual rent is well below the market rent, the capitalised gap constitutes lease rights in the tenant's favour. These rights, an intangible element attached to the business, reduce the value of the unit for the landlord, who receives an income below the property's potential.
• The theoretical cost of recovery. Recovering the unit requires, save for a serious and legitimate reason, paying an eviction indemnity. This latent cost must be taken into account by a buyer who would consider operating it themselves.

For valuation, the rule is simple: an occupied unit is valued by capitalising the real in-place rent, factoring in the effect of the protective status, and not as if it were vacant.

6. Unit in a condominium: check the authorised use

A ground-floor unit is part of a condominium. The condominium bylaws can restrict, or even prohibit, certain activities — catering, sale of drinks, noisy or nuisance-generating activities — even for a lot located on the commercial ground floor. Local planning rules can, for their part, condition the use depending on zoning.

Before any acquisition or valuation, you must therefore check the actually authorised use, and compare it with the planned activity. A unit whose intended activity is not permitted by the bylaws is mechanically worth less than a unit with free commercial use: the restriction limits the pool of buyers and the achievable rent. This check is an integral part of the scope of a valuation: the use assumptions and restrictions adopted are documented in the report.

7. The valuation process, in practice

• Inspection and survey: measurement of areas, configuration, frontage, height, condition, mezzanine and storage.
• Location analysis: classification of the artery, footfall, commercial surroundings, no.1 / 1bis / 2 position.
• Weighted area: assignment of coefficients by zone, justified in the report.
• Legal and rental situation: current lease and 49-16 status, in-place rent vs market, use authorised by the condominium and planning rules.
• Dual approach: direct comparison (adjusted transactions) and capitalisation of rental value, then reconciliation of the results.
• Report compliant with RICS standards: basis of value, assumptions, methodology and reasoned conclusion — delivered in 5 to 8 days (48-72 h express).

Such a valuation informs a decision to buy, sell or let, and provides a solid basis to support your position with third parties in an amicable negotiation. Note: a private valuation serves to decide and to negotiate; in litigation, it is the judge who appoints the judicial expert.
