How the DGT's position has evolved

Settled doctrine High confidence 27 rulings · 2014–2026

Current position

To apply the 10% rate in rehabilitation, the works must meet a qualitative requirement (more than 50% of the cost in structural elements, facades, roofs, or analogous/ancillary elements) and a quantitative one (cost exceeding 25% of the value of the building excluding the land). Suitability for residential use is determined by objective design and construction characteristics, without the certificate of habitability being mandatory.

The DGT's position remains constant in the definition of rehabilitation requirements, always requiring the 50% threshold in structural or ancillary elements and 25% of the property value. The evolution shows greater precision in determining suitability for residential use, clarifying that the certificate of habitability is not necessary.
