Building rights
In short
Building rights answer "how much, and what, can be built here?". They are measured mainly in square metres (a percentage of plot area), floors and housing units. More rights means more valuable land.
The professional explanation
Rights are set by the detailed plan covering the plot and itemised in the permit information file. Main areas (housing, commerce) are distinguished from service areas (parking, storage, safe rooms, stairwells), each with its own rules.
Alongside rights come limits: maximum site coverage, building lines (distance from plot boundaries), maximum height, number of units and parking standard. "Theoretical" rights are not always fully usable because of these limits or the plot's shape.
Unused rights are an asset: on an existing house it is sometimes possible to add a floor or a unit, which directly affects value.
Example from the field
A 500 m² plot with 60% main-area rights over two floors allows about 300 m² of main area. If the plan permits two units, a semi-detached pair can be planned, which attracts a completely different buyer pool than a single house.
Why it matters in a deal
- Value derives from rights; two equal-sized plots can be worth very different sums.
- Rights are verified against a current information file, not "what the neighbour built".
- Added rights under a new plan may trigger a betterment levy on realisation.
