An apartment owner in Arad requested to expand his apartment by 30 m² on the roof of the building where he resides, but encountered an unexpected demand from the municipality. The request, which was in accordance with the local building plan and did not include irregularities or exemptions, raised issues when the municipality discovered that the building was constructed with a 60 cm irregularity. As a result, the municipality demanded that the resident prepare a new urban building plan (TBA) to approve the expansion request. The case highlights the difficulties that can arise in construction processes, even when requests seem legal and orderly. The owner found himself needing to deal with complex bureaucracy, which could delay the long-desired expansion process. The case raises questions about construction management and municipal oversight, especially in cases of building irregularities that have persisted for many years without being addressed.
