Short Definition
Remodeling is altering the design of a building or unit or the layout of its spaces or components — demolishing walls, adding a room, floor or annex, merging two units or changing the use — so that its form or function differs from the original, rather than simply restoring it to its previous state.
Overview
Legal Basis
The Saudi Building Code Implementation Law (M/43 dated 26/4/1438H) applies the code to existing buildings upon change of use, extension or alteration (Art. 2), makes compliance a condition for alteration and change-of-use permits (Art. 6), allows work to be stopped, occupancy prevented or the building evacuated for dangerous violations (Art. 11), and imposes fines of up to SAR 1 million per violation plus suspension of the practice licence (Art. 12). The Law of Ownership, Partition and Management of Real Estate Units (M/85 dated 2/7/1441H) requires general-assembly approval to re-partition or change the use of the jointly owned property (Art. 3) and for any change to its external appearance (Art. 30), and prohibits harming the structural frame or façades (Art. 9). The Civil Transactions Law bars the tenant from altering the premises without the landlord's consent (Art. 432) and governs the fate of the tenant's additions at the end of the lease (Art. 436).
Practical Example
A villa owner in Riyadh wants to convert the ground-floor annex into a separate rentable flat and add a room above the car park. He hires an engineering office to prepare revised drawings and a structural study of the new room's loads and submits them through Balady's add/modify building components service with a supervising office and a contractor. The works cost SAR 180,000 plus SAR 15,000 for design and supervision. The flat is expected to rent for SAR 30,000 a year, recovering the investment in about 6.5 years. Had he built without a permit, he would have faced a building-code fine and difficulty documenting a proper lease for the new unit.
Common Mistakes
- ✗Carrying out structural changes (removing a load-bearing wall, cutting a slab or adding a floor) without an engineering study and a permit update.
- ✗Changing façades or use in a jointly owned building without the owners' association general assembly's approval.
- ✗A tenant altering the unit without the landlord's consent, followed by an end-of-lease dispute over removal or compensation.
- ✗Splitting a villa into rental flats without a permit, exposing the owner to violations and complicating documentation and utilities.
- ✗Overlooking the effect of the change on fire safety, ventilation, services and exits.
International Differences
Most countries require a permit for structural alterations or changes of use: in Turkey they are called "esaslı tadilat" (substantial alterations) and need a permit, and in the UAE, unit alterations in shared buildings need approval from the developer or owners' association and the municipality. In the United Kingdom, some alterations need both planning permission and building-regulations approval. Saudi Arabia is distinctive for a single electronic service for adding and modifying components via Balady and a building-code fine that can reach SAR 1 million per violation.
