Unauthorised building work in Poland: consequences and possible legalisation

The problem may concern construction without the required permit, without notification or despite an objection. Another situation is the execution of works with a significant departure from the approved documentation. Not all infringements are dealt with in identical proceedings. Their nature must first be established, instead of using the word “samowola” as a single label for every non-compliance.

With a roof, a frequent source of misunderstanding is calling a reconstruction a renovation. Restoring the original condition may involve using different materials. Raising the roof or changing the structural parameters is, however, a different scope. What matters is the effect of the works, not the title of the contract with the crew. The documents and the condition of the building should be compared by a person with the appropriate competences.

Collect the decisions, notifications, designs and documentation of changes. Establish which elements were executed differently and when the works were completed. Photographs, protocols and reliable documents from the construction period are helpful. Do not try to fit the dates to the expected procedure. Establishing the actual course of the works is the basis for further legal and technical assessment.

If there is a safety risk, limiting access and assessing the condition of the structure take priority. Do not go onto a suspect roof to take measurements yourself. Do not cover damage with new sheet metal or insulation either. The legality of the works and the safety of the building are separate issues that may require clarification in parallel.

There is no such guarantee. In the ordinary procedure, the conditions set out in the Act must be met, the required documents submitted and the obligations indicated by the authority fulfilled. Compliance with the relevant regulations and the technical condition are significant. The legalisation fee is not a simple price for consent for any building in any location.

The cost and scope of the proceedings depend on the classification of the building and the infringement. A sum found in another case should not be used as a certain budget. Inventory, expert opinion, documentation and adjustment works may be added to the expenses. If the conditions for legalisation cannot be met, the consequences may go further than merely completing the documents.

The Act provides a simplified procedure for certain constructions completed at least twenty years earlier. The mere passage of that period does not legalise the building. A procedure and documents are required, including an appropriate inventory and technical expert opinion. Among other things, the possibility of safe use in accordance with the existing or intended manner is assessed.

A separate solution covers works specified by statute that were completed at least ten years earlier. It applies, among other things, to significant departures from a decision or design. These provisions must not be combined into the slogan “unauthorised construction disappears after ten years”. The type of infringement, the time of completion and the safety conditions must be analysed separately for each specific case.

Under certain conditions, the supervisory authority may instruct the investor to remove significant departures. The instruction is documented, and the authority then checks that the works have been brought into line. This is a statutory procedural mechanism, not an entitlement to knowingly disregard the design. Not every situation has to end with this milder route being applied.

In practice, the easiest way to avoid the problem is before installation. If the roof pitch, the layout of openings or the support is to change, an assessment by the designer is required. Changing the covering system can also affect the structure and details. Written agreement on the relevant change is organisationally safer than a later attempt to show that the contractor considered it invalid.

Before a major renovation, compare the existing roof with the available drawings and official documents. Pay particular attention to added storeys, the changed roof pitch and the conversion of the attic. The purchase of a property or a new insurance policy does not automatically confirm the lawfulness of earlier works. It is also not enough to rely on the assurance that a neighbour has had a similar solution for a long time.

Where the documentation is incomplete, prepare a plan to reconstruct it and clarify the condition of the building. Separate the scope of formal regularisation from the new investment. This ensures that the order for sheet metal, sandwich panels or insulation is based on the correct design. Starting a renovation without identifying earlier changes may reveal the problem only after the old roof has been stripped, when the cost of downtime is already significant.
