MPZP, the general plan and WZ: the three documents that decide what you can build
The question "is this parcel buildable" has no single answer — it has three, written in three different documents with different legal force. Most buyers meet them in the wrong order: price first, WZ second, the plan last. This guide builds the system from the top: what the municipality adopts, what binds the owner, and where you will see each document in Centria before signing anything at the notary.
The system in three layers
Polish spatial planning after the 2023 reform is a hierarchy: the general plan sets the direction for the whole municipality, the local plan turns it into binding rules for specific areas, and the WZ decision operates where no local plan exists. Each document binds something different — which is the source of most misunderstandings when buying land.
| Document | Adopted by | Who it binds | Where in Centria |
|---|---|---|---|
| General plan (POG) | municipal council — mandatory, for the whole gmina | the municipality: it binds local plans and WZ decisions, but is not a basis for a building permit | POG zone layer on the land map, the gmina-status background, the general-plan monitor, zone parameters in the report |
| Local plan (MPZP) | municipal council — voluntary, for selected areas | everyone: an act of local law, the direct basis for a building permit | MPZP layer on the map, the report's planning chapter with extracted parameters |
| Zoning decision (WZ) | mayor — on application, for a single investment | the addressee of the decision: it substitutes for a plan where none exists | the planning verdict in the report: whether a WZ is obtainable here at all |
Local plans cover roughly one third of Poland's area. On the remaining two thirds the WZ path decides — and from 1 September 2026 its availability depends on the general plan.
MPZP — local law that binds directly
The local plan is the only one of the three that binds everyone. It consists of a drawing and the resolution text, and for each area sets the designation (symbols such as MN — single-family housing, MW — multi-family, U — services, P — industry and warehouses, R — farmland, ZL — forest) and the parameters a building permit cannot exceed.
- development intensity (FAR) — total floor area to plot area, typically 0.1–0.8 for single-family zones
- maximum building coverage — what share of the plot may sit under the building (typically 20–40%)
- minimum biologically active surface — how much of the plot must stay green (typically 30–60%)
- maximum building height (typically 8–12 m) and roof geometry, including pitch
- building lines — mandatory or maximum setback from the road
- minimum area of a newly split plot — the number that decides whether land can be subdivided
On the land map the "Local plan (MPZP)" layer shows the boundaries and drawings of binding plans, and where we have collected plans as vectors — one national legend for the whole country. In the parcel report the planning chapter reads the zone symbol for the specific parcel, and from the resolution text we extract the parameters — height, intensity, roof — and compute an indicative envelope of what could stand on the plot.
The general plan (POG) — a direction for the whole gmina
The general plan replaced the old studium in the 2023 reform. Unlike the studium it is mandatory and binding — but it binds the municipality, not the owner: local plans and WZ decisions may not contradict it, yet you cannot get a building permit from it directly. The municipality divides its whole territory into 13 kinds of planning zones and sets municipal urban standards — height and intensity ceilings no later plan can exceed.
For a buyer the zones that matter most are SJ (multifunctional with single-family housing) and SW (with multi-family) — these mean a residential direction. SO (open zone) is in practice a freeze on new development, and SR (agricultural production) excludes housing. A separate role belongs to the OUZ — the infill development area: within it, WZ decisions remain obtainable after the general plan takes effect. Outside the OUZ, without a local plan, new development becomes impossible.
The "POG zones" layer on the land map shows adopted zones in the national 13-colour legend, separate layers show the infill development areas (adopted and draft), and the background under the zones shows every gmina's status: plan adopted, annulled by the wojewoda, no plan, or not measured. The full table of resolutions for all 2,479 gminas, updated daily straight from the provincial official gazettes, lives in our general-plan monitor. In the parcel report, where the zone is already published, we show its parameters: maximum height, intensity and minimum green share.
WZ — the decision when there is no plan
The zoning decision is an individual ruling for one investment on land without a local plan. The classic conditions of art. 61 of the planning act come down first to "good neighbourhood": at least one plot accessible from the same public road must be developed in a way the new investment can match in function and scale. Add road access, sufficient utilities and no need to de-agriculture the land.
The reform changes this path fundamentally. Once a general plan is in force, new WZ decisions are issued only inside the infill development area and must comply with the municipal standards; new decisions also get an expiry — 5 years (earlier ones remain indefinite). From 1 September 2026 a municipality without an adopted general plan issues, as a rule, no new WZ at all, and from 1 January 2027 only someone with legal title to the property may apply — a prospective buyer can no longer test a parcel "on spec".
The parcel report folds these layers into one planning verdict. If a local plan is in force — the verdict reads "MPZP" and no WZ is needed. If there is none, we check the general plan and the OUZ: a parcel inside the infill area gets "WZ obtainable", a parcel outside it — a plain statement that no new decision is issued here. And when the gmina has not adopted a general plan at all, the verdict says so directly: frozen until a resolution. We also distinguish "the source answered: absent" from "the source did not answer" — a registry outage is never reported as the absence of a plan.
Which document wins on a given parcel
| Situation | What decides | What it means for building |
|---|---|---|
| An MPZP exists | the local plan | you build to the plan's designation and parameters; no WZ needed |
| No MPZP, gmina has a POG, parcel inside the OUZ | a WZ within the POG standards | development possible after obtaining a WZ (new decisions: valid 5 years) |
| No MPZP, gmina has a POG, parcel outside the OUZ | the general plan | no new WZ is issued — only a future local plan can help |
| No MPZP and no POG (after 1 September 2026) | the reform's transitional rules | frozen: no new WZ and no new plans until a POG is adopted |
The fourth row's transitional state covers most municipalities in Poland — exact counts, updated daily, are in our general-plan monitor.
On 31 August 2026 the old studium documents lapsed and the statutory deadline for adopting general plans passed. What exactly changed on 1 September, and which scenario your gmina is in, is covered in a separate guide: "1 September 2026: why most Polish municipalities can no longer issue zoning decisions".
Frequently asked questions
Not directly. SJ is a direction: the municipality foresees single-family housing here. The right to build comes only from a local plan consistent with that zone, or from a WZ decision — which requires the parcel to lie inside the infill development area.
No. WZ decisions issued before the new rules remain valid indefinitely. The five-year expiry applies to decisions issued after the reform.
We read the official gazettes of all 16 voivodeships — the channel where every general-plan resolution must be published to take effect. We also account for the wojewoda's supervisory rulings: a gmina with an annulled plan has no plan in force. The results are published in the general-plan monitor.
The report distinguishes two situations: the registry answered "no plan", or the registry did not answer at all. The second is a data gap, not a fact about the parcel — and we label it as such instead of guessing.

The parcel report reads the MPZP, the general-plan zone and WZ obtainability for the parcel you point at, and folds them into one verdict — marking which source answered and which stayed silent.
