Extraordinary maintenance works are the works that are necessary to keep the entire building in good condition and, therefore, are those that serve to replace or modify even structural parts of the building or those necessary to create new systems, totally different from those existing.
What can be done with extraordinary maintenance?
- replacement of external fixtures and windows or shutters with shutters, with modification of material or type of fixture
- ancillary and appurtenant works that do not involve an increase in volumes or useful surfaces, construction of technical volumes, such as thermal power stations, lift systems, safety stairs, flues
- creation and integration of sanitation services without altering volumes and surfaces
- closing or opening internal doors that do not modify the distribution scheme of the real estate units and the building
- refurbishment of stairs and ramps
- construction of fences, boundary walls, and gates
- replacement of roof slabs with materials other than pre-existing ones
- replacement of internal partitions, without altering the type of real estate unit
- realization of supporting elements of single structural parts
- interventions aimed at energy saving.
- Static consolidation works are also included in the extraordinary maintenance. If a building is collapsing due to a worn or undersized structural element, it must be replaced or reinforced. The chains used to improve the resistance of the building to the earthquake are also static consolidation works.
Some clarifications on MS
Those that alter the shape, shape, volume or overall surface of the building and its intended use are not extraordinary maintenance interventions.
For example the construction of a veranda to cover a terrace changes the shape, the shape, the volume and changes the intended use from non-residential to residential and, therefore, it is not extraordinary maintenance, but building renovation.
The replacement of the flat roof with a pitched roof is not extraordinary maintenance. This intervention increases the volume and is a superelevation (Criminal Cassation, section III, May 6, 1994).
The redistribution of the house through the demolition of partitions and the modification of the rooms does not alter either the shape, the shape, the volume or even the intended use, and is therefore extraordinary maintenance.
