Farmland conversion (odrolnienie): two stages, real costs, and when it's free
“Odrolnienie” is really two different proceedings, before different authorities, at different stages — and priced very differently. The good news: for most single-family plots the final bill is low or zero. The bad: for top-grade land outside cities, the first barrier can be impassable.
Stage 1: the designation change — at plan level
Agricultural land may be designated for non-agricultural purposes only in a local spatial development plan. For grade I–III land this requires the consent of the minister for rural development — requested by the municipality within the planning procedure, not by the owner. An important exception: since 2013, ministerial consent is not required for farmland within city administrative boundaries.
An owner cannot “convert” a parcel by application. If the plan designates the land as agricultural — you wait for the municipality to change the plan. That is why soil grade and the planning zone weigh on land price more than area itself.
Stage 2: exclusion from agricultural production — before construction
Once the designation permits building, the land must still be actually excluded from agricultural production before the building permit. The starosta issues the decision. The duty covers mineral-soil grades I–IIIb and all organic soils; mineral grades IV–VI are excluded without any decision or fee.
What it costs: the one-off charge and annual fees
| Soil grade | Arable land & orchards (PLN/ha) | Meadows & pastures (PLN/ha) |
|---|---|---|
| I | 437,175 | 437,175 |
| II | 378,885 | 361,398 |
| IIIa / III | 320,595 | 291,450 |
| IIIb | 262,305 | — |
| IVa / IV | 204,015 | 174,870 |
| IVb | 145,725 | — |
| V | 116,580 | 116,580 |
| VI | 87,435 | 87,435 |
One-off charge rates under art. 12(7) of the farmland-protection act, per hectare of excluded land.
On top of the charge come annual fees: 10% of the charge, payable yearly for 10 years. Sounds severe — but the deduction rule is decisive: the charge is reduced by the market value of the excluded land as at the exclusion date. Where land is expensive, market value often exceeds the table rate and the charge collapses to zero. Real cost appears mainly where high-grade land is cheap.
Exclusion of up to 500 m² for a single-family house is exempt from the charge and the annual fees (art. 12a). For a typical house build, fees apply only to the excess above that threshold.
Forest is not a field: deforestation consent
Forest land (Ls) has a separate, much harder regime: the designation change requires consent of the environment minister (state forests) or the voivodeship marshal (private), and refusals are the norm rather than the exception. Wooded land outside the forest registry (Lz) is easier. Buying a “parcel with trees”, check whether it is Ls or Lz — the difference can be worth the whole parcel.
Frequently asked questions
If the plan (or a WZ) permits development: grade-IV mineral soil needs neither an exclusion decision nor fees. The grade I–III barrier does not concern you.
Within city limits the ministerial consent is not required, so the planning stage depends on the municipality. Exclusion from production still needs a decision and fees (grade II), but the market-value deduction in cities usually brings the charge to zero.
The duty falls on whoever obtains the exclusion decision — in practice the investor starting construction, regardless of when they bought the land.
Price the conversion for a specific parcel
The parcel report reads soil grades from the registry, applies the statutory rates and the market-value deduction — and shows the estimated exclusion cost for your parcel.
