There are many cases where a property complies with urban planning and building regulations, but its current condition has never been reported to the Building Registry, resulting in a non-existent or non-compliant cadastral floor plan. In such cases, a cadastral update may be carried out, which must be prepared by a licensed professional. Please note that failure to update the records will result in a penalty if the update is made more than one month after the completion of the work and up to five years thereafter. If the work performed did not involve any expansion beyond the original floor plan, it will be sufficient to file the updated floor plan with the Building Registry, accompanied by the DoCfa change form. If, however, the work carried out also involved an expansion of the building’s original floor plan, it is essential to record this change on the Land Registry map by filing the “Cadastral Map Type” document—prepared following on-site surveying to determine the new building outline—before submitting the new floor plan. If, however, the urban planning review reveals that work was carried out without the necessary planning permission or in violation of it, the situation becomes more complicated, and a solution must be sought on a case-by-case basis.
