Decisions before the building design.

Advisory and design for industrial, agricultural and technical buildings. We consider plot capacity, documentation and the formal path together.

Change an assumption

Permit or notification

A threshold changes the construction procedure.

The storage system's nominal energy capacity, the station's built-up area and the fence height decide the procedure. Crossing a threshold may mean a notification or a building permit. Move the values to check the result, assuming no statutory exceptions apply.

  1. Free-standing electrical energy storage, nominal energy capacity

    250kWh

    Notification

    Above 30 up to 300 kWh. The site plan needs fire-safety agreement. The Fire Service is notified when installation ends and use begins, with a plan of the storage location and data relevant to rescue-team safety.

    art. 29(1)(40), art. 30(3)

  2. Free-standing single-storey transformer station

    24m²

    Notification

    Built-up area up to 35 m², container stations included.

    art. 29(1)(3)

  3. Fence

    2.00m

    No permit, no notification

    Height up to 2.20 m.

    art. 29(2)(20)

Notification. The authority has 21 days from receipt of the notification to object. Works may start once that period ends without an objection, or earlier after a certificate of no grounds for objection. An order to supplement the notification interrupts the period. art. 30(5), (5aa), (5d)

Building permit. Without an exempting provision the rule applies: building works start on the basis of a building permit. art. 28(1)

Other conditions count alongside the thresholds, such as location in a protected area or the local plan. We check them for the specific plot.

Scope of advice

  1. Site analysisBefore you buy a plot

    We check what can be built on it and at what scale, before the price and the contract are fixed: local zoning plan or zoning decision, utilities, access, ground conditions and environmental constraints.

  2. Functional brief and performance requirements (PFU)Before you start the design or a tender

    A description of the investor's needs that becomes the basis of the design or of a design-and-build tender.

  3. Cost and scheduleWhen the budget does not match the design

    Investor's cost estimate, a budget with contingencies and a schedule from decision to acceptance. We verify the cost estimate and look for savings in the programme and the solutions.

  4. Tender and contractBefore a tender for a contractor

    We prepare the scope, the selection criteria and the contract so that the offers are comparable. We compare the offers and review the contract terms.

  5. Supervision and acceptancesDuring construction

    Investor's supervision inspector, control of progress and quality, partial acceptances, acceptance of concealed works, final acceptance and the occupancy permit.

Where projects most often stall

  1. Zoning decisions only with a general plan

    From 1 September 2026 new zoning decisions (WZ) are possible only in a municipality with a general plan. This must be checked before buying a plot with no local zoning plan (MPZP).

  2. A permit that lapses

    A building permit lapses if construction does not start within 3 years of the decision becoming final, or is interrupted for longer than 3 years.

Questions and answers

When is a notification enough instead of a permit?

For example, for single-storey farm buildings and shelters connected with agricultural production of up to 300 m² of footprint, with a span of up to 7 m and a height of up to 7 m, and an area of impact within the plot boundaries. The authority has 21 days to object.

Is an occupancy permit needed after building a hall?

For industrial buildings, yes. Storage facilities (warehouses, cold stores, hangars, shelters) may be used after notifying the district building inspector (PINB), provided no objection is raised within 14 days.

How long does the district head (starosta) have to issue a building permit?

65 days from filing the application, excluding time for supplementing the documents.
