What the coefficient really allows
Two parcels of nine thousand square metres, a kilometre apart, can be entirely different assets. The difference is a number most buyers never ask for.
Area is not the number that matters
Buyers ask first about square metres. It is the wrong opening question. What determines value is how much of that area you may build on, and how much total floor space you may create.
Lebanese zoning expresses this through coefficients set by the classification applying to the zone — a surface ratio governing the building's footprint, and a total exploitation ratio governing cumulative floor area across all levels.
A worked comparison
Take two parcels of 9,000 square metres. One sits in a zone permitting a total exploitation of 0.5; the other in a protected agricultural or green classification at 0.05.
The first supports roughly 4,500 square metres of built floor area — a substantial villa, or several. The second supports around 450, and often carries additional constraints on what may be built at all. Same area, same map, entirely different asset. The price should reflect that, and frequently it does not, because the seller is quoting per square metre of land.
Setbacks and height quietly do the rest
Even where the coefficient is generous, minimum distances from boundaries and roads, permitted number of levels and maximum height determine what shape the permitted volume can take. On a narrow or steeply sloped parcel these can make the theoretical allowance unbuildable in practice.
Slope deserves particular attention in the heights. A terraced parcel above Faqra or Tannourine may have a fine coefficient and still require retaining work that costs more than the land.
Where to get the real figure
The municipality holds the classification for the zone, and an architect or surveyor can confirm what it permits on a specific parcel. That is an afternoon's work and a small fee.
Treat a seller's stated coefficient as a claim to verify, not a fact. It is the most commonly overstated number in Lebanese land sales, and it is also the easiest to check.
