Does a neighbourhood plan override the zone regulations?
Yes, within its perimeter. It specifies, supplements or replaces the general rules. Outside the perimeter, the ordinary municipal regulations continue to apply unchanged.
PQ / PPA
Neighbourhood plan and detailed land-use plan
A neighbourhood plan or detailed land-use plan is a binding plan that specifies, supplements or replaces municipal rules within a defined perimeter. It typically governs siting, volumes, heights, access and outdoor spaces. Cantonal names vary — plan de quartier, PPA, Quartierplan, Gestaltungsplan — for the same family of instruments.
Definition and legal framework
These belong to the family of special plans, as opposed to the general land-use plan that allocates the whole municipal territory between zones. Adopted by the municipality and approved by the canton, they carry the same binding force as the zone regulations — but only inside their perimeter.
Their logic trades flexibility for quality: the authorities may accept higher density, non-standard siting or greater height in exchange for requirements on public space, parking, massing or energy performance. The name changes from canton to canton; the legal mechanics are comparable.
What it changes for your parcel
This is the most expensive blind spot in a plot analysis. Reading the zone index without checking for a special plan leads to overestimating capacity: the plan can cap height below the zone allowance, impose a specific siting, or freeze part of the perimeter as open space.
The opposite also happens and is rarely exploited: a neighbourhood plan can grant more than the ordinary regulations. A plot that looks saturated against the zone index may hold real potential if its perimeter is covered by a more generous plan.
How to obtain it
Ask the municipal planning office whether the plot falls within the perimeter of a plan in force, and request the plan AND its written rules — both documents apply together. The cantonal geoportal usually shows perimeters; the written prescriptions are not always published there.
Frequently asked questions
How do the various special plans differ?
They are cantonal names for the same family of instruments. The vocabulary changes between cantons, but in every case it is a binding detailed plan over a defined perimeter.
How do I know whether my plot is affected?
The cantonal geoportal shows the perimeters of plans in force, and the municipal planning office confirms. An old plan that was never repealed remains applicable.
