بدر الحسني | Bader Al Hassany11 min readIf you are planning to build your dream home, or investing in the Kingdom’s real estate sector, you have certainly heard the term “Saudi Building Code” repeated a lot in real estate gatherings and engineering offices. In the past, some thought that the code was just paperwork and bureaucratic complications, but the reality lived today in 2026 proves that it is the cornerstone for protecting your financial investment and ensuring the safety of your family.
In this guide on Aqar Blog, we will explain this code, its most prominent requirements, and how it actually affects your construction journey.
The Saudi Building Code is an integrated technical and legal document that sets the “minimum” standards for safety, quality, and sustainability that are not allowed to be compromised when designing or executing any building in the Kingdom. The code does not dictate how to design your home aesthetically, but rather ensures that this house is built on sound engineering foundations that resist harsh climatic conditions, protect it from cracks, and reduce the likelihood of catastrophic risks such as fires or electrical short circuits.
The code branches into several specialties, but if we want to look at the core standards that touch residential and commercial buildings on a daily basis, we find them summarized in four main pillars:
The code cares about the finest details of foundation; starting from the mandatory soil testing before construction to determine the appropriate type of footings, passing through reinforcing steel diameters and concrete mixing ratios, all the way to the methods of insulating tie beams to prevent the leakage of moisture and salts that erode the structural frame over the years.
Thermal insulation for walls, roofs, and windows (using double glazing) is a mandatory condition with no compromise across all regions of the Kingdom. The goal here is to protect you as a citizen from high electricity bills; as insulation contributes to reducing the pressure on air conditioning units and lowering energy consumption by up to 40%.
The code requires strict specifications for wiring and conduits carrying current to withstand overload without causing thermal short circuits. It also mandates the presence of effective grounding (Earth) systems and smart residual current devices to protect building occupants from the risks of electrocution.
The code sets precise requirements for smoke detectors, distribution of fire extinguishers, and the use of flame-retardant paints and insulation, in addition to defining clear escape routes and means of egress and applying fire separation walls to prevent the spread of fire between zones.
One of the very repetitive points that causes confusion among owners is “setbacks”, which are the minimum legal distances that must be left empty between the building body and the land boundaries from the four sides.
Applying setbacks correctly is not just municipal regulation, but a purely security and environmental requirement; it ensures the entry of natural lighting and ventilation into the house, maintains your privacy and that of your neighbors, and most importantly, provides safe paths for civil defense teams for rapid intervention in emergencies.
Applying the code goes through a clear and interconnected digital and regulatory path to ensure quality, divided into main stages:
First Stage (The Engineering Office): You cannot start your project without contracting with a certified engineering consulting office. The office takes on preparing the plans (architectural, structural, electrical, mechanical) to perfectly match the code before uploading them via official platforms.
Second Stage (Balady Platform and Building Permit): Plans are reviewed and procedures are automated via “Balady” platform to issue the building permit. One of the most important current requirements for issuing the permit is issuing the latent defects insurance policy.
Third Stage (Execution and Field Inspection): While the contractor is building, the site is subject to mandatory scheduled inspection visits by certified technical supervisors to ensure that what is being built on the ground literally matches the approved plans.
Fourth Stage (Occupancy and Compliance Certificate): After construction is completed and final testing of systems is conducted, the occupancy certificate (or compliance certificate) is issued via Balady platform. This certificate is the official proof that the house is safe and completely ready, and without it, you will not be able to connect basic utilities such as electricity and water to the building.
The difference between the old Saudi code (which was applied as a guide and was not fully binding) and the new Saudi Building Code (mandatory and updated for 2026) is a fundamental difference that changed the concepts of construction in the Kingdom. In the past, the process depended heavily on the diligence of contractors or engineering offices, and there was no strict reference guaranteeing the quality of the final output. Now, the code has turned into a “strict system” that links the extraction of building permits and occupancy certificates to full technical and field compliance.
To understand the differences clearly, the following table summarizes the most prominent differences between the two codes:
| Comparison Aspect | Previous Building Code (Traditional) | New Saudi Building Code (Current) |
| Mandatory Application | It was optional or applied as a guide in most residential buildings. | 100% Mandatory for all new residential and commercial buildings without exception. |
| Latent Defects Insurance | It did not exist, and the owner bore the cost of any structural defect appearing after occupancy. | An essential and core condition; where the contractor and developer are obliged to provide comprehensive 10-year insurance against structural defects. |
| Thermal Insulation (Energy) | It was limited to roof insulation only and without being field-audited. | A strict system that includes walls, roofs, and double glazing (Thermal Break) to reduce bills by up to 40%. |
| Field Inspection and Audit | Limited to general municipal visits at foundation and completion. | Precise periodic inspection in 4 basic stages (Foundations, Structure/Skeleton, Insulation, Finishing) via certified inspectors. |
| Universal Accessibility | It was optional and within the diligence of the building’s architectural design. | Strict mandate to prepare corridors, ramps, and restrooms to suit people with disabilities. |
| Safety and Fire Systems | Rudimentary requirements and depended on the building’s operational capacity only. | Strict requirements to connect smart smoke detectors, distribute fire extinguishers, and use flame-retardant paints. |
Continuous updates focused intensively on “compliance and full digital integration”; so that tampering with specifications is no longer possible; because the supervising engineering offices and inspection companies are directly linked to the “Balady” platform and insurance companies. Any violation of requirements prevents the activation of the latent defects insurance policy, and consequently results in refusal to issue the occupancy certificate and imposing financial fines that may reach up to 500,000 SAR.
Here is a comprehensive and reliable detail covering the topic of regulatory setbacks, and the requirements of the Saudi Building Code for various building sectors (residential, commercial, industrial, hospitality, and others) based on the approved updates and regulations:
It is considered one of the most important topics covered by the new building code system, we will explain it simply. A setback is the legal separating distance that must be left completely free of construction between the outer land deed boundaries (ownership) and the outer wall of the building.
Safety and Fire Prevention: Preventing or slowing the spread of fire from one building to another, and providing sufficient space for the passage of civil defense vehicles and ambulances.
Health and Environment: Ensuring the entry of direct sunlight and providing natural ventilation for the building and neighboring buildings.
Privacy: Providing a visual safety distance that prevents neighbors from overlooking each other.
Service Networks: Allocating underground and overground corridors for extending water, sewage, electricity, and gas networks without structural conflict.
Practically, there is integration between the building code and the municipal requirements (municipalities):
Municipality and Amanah: Determine the “setback percentage” or the distance in meters (e.g., front setback 1/5 of the street width, and side and rear setbacks of no less than 2 meters in residential) based on the street width and neighborhood planning.
Building Code: Intervenes to impose safety conditions within this space (e.g., preventing the placement of main openings or windows if the setback is less than a certain distance, or imposing fire-resistant walls without openings entirely if construction is on the boundary/zero-lot-line).
The Saudi Building Code classifies facilities based on “occupancy type”, “intensity of use”, and “risk level”. Here is the breakdown of requirements for each sector:
Covers standalone villas, townhouses, and residential buildings that do not exceed specified floors.
Most Prominent Requirements:
Mandatory Thermal Insulation: Insulation of roofs and walls and the use of aluminum profiles and double glazing to prevent thermal leakage to lower energy bills.
Latent Defects Insurance: Mandatory issuance of a prior insurance policy covering structural defects for 10 years as a condition for issuing the building permit.
Electrical Safety: Imposing the grounding system (Earth) and residual current circuit breakers to protect residents from electrocution, and specifying insulated paths for wiring.
Soil Testing: The necessity of conducting a certified soil report to design the structural footings and foundations to prevent future building settlement.
Includes commercial complexes (malls), shops, corporate offices, and showrooms.
Most Prominent Requirements:
Central Firefighting and Alarm Systems: Mandatory installation of automatic sprinkler networks (Sprinklers), fire cabinets, and smoke detectors connected to a main control panel.
Evacuation Routes and Means of Egress: Determining the width of corridors, stairs, and emergency doors (fire-rated) based on the mathematical calculation of the expected number of visitors.
Universal Access: Mandatory preparation of facility entrances, wheelchair ramps, and dedicated restrooms for people with disabilities and the elderly.
Additional Approvals: Requiring strict approval and auditing from the General Directorate of Civil Defense before operation.
Includes hotels, furnished apartments, and resorts. Given that guests sleep in the facility and do not know its routes well like residents of a home, the code raises the safety bar higher:
Most Prominent Requirements:
Smoke Management Systems: Imposing mechanical pressurization fans in emergency stairwells to prevent smoke from entering them during a fire, securing a safe path for guests.
Emergency Lighting: Mandatory presence of emergency lighting powered by self-contained batteries to guide guests to exits upon main power failure.
Flame-Retardant Finishing Materials: Carpets, curtains, wallpapers, and fixed furniture must meet certain specifications that slow flame spread and do not produce dense toxic gases upon combustion.
Acoustic Insulation: Requiring precise acoustic insulation standards between rooms and floors to ensure guest comfort.
Includes factories, workshops, and storage warehouses. The focus here is on the type of materials manufactured or stored and their hazard level.
Most Prominent Requirements:
High-Risk Separation: Imposing reinforced concrete and fire-rated walls and floors separating hazardous manufacturing/storage areas from administrative offices.
Heavy Mechanical Ventilation: Imposing extraction systems and mechanical fans to ensure no accumulation of toxic or flammable gases and vapors in the work environment.
Spill Containment: Requiring floors to be designed with specific slopes and drainage channels for chemical or petroleum plants to contain any material leakage without reaching the public sewage network.
Special Fire Suppression Systems: In high-ceiling warehouses, the code mandates the installation of advanced firefighting networks that penetrate racks (In-Rack Sprinklers) to ensure fire suppression at its onset.
Most Prominent Requirements:
Power Continuity: Imposing massive backup generators and Uninterruptible Power Supply (UPS) systems to ensure electricity is never cut off from operating rooms, intensive care units, and life-support devices.
Air Filtration and Room Pressure: Using high-efficiency (HEPA) filters and designing isolation rooms with negative pressure (to prevent epidemics from exiting) and operating rooms with positive pressure (to prevent microbes from entering).
Very Wide Corridors: Designing corridors and ramps with a width that allows smooth passage and transport of mobile medical patient beds and internal stretchers during evacuation.
The application of the new building code no longer depends on paper reports; rather, it is done through full technical integration:
Balady Platform: Engineering plans are uploaded and electronically audited to ensure compliance with all the aforementioned codes before issuing the building permit.
Compliance and Inspection Platform: Mandatory field visits for inspectors to the site are scheduled to match construction step by step.
Occupancy Certificate: The certificate (which allows connecting electricity and water) is not granted until the facility completely matches the occupancy type designated for it in the permit.
It is a unified national system that enforces a binding set of engineering requirements and standards applied to residential and commercial projects, to ensure the highest levels of quality and structural safety, reduce energy consumption and electricity bills, and protect buildings from structural cracks in the future.
You can officially verify this by ensuring that the occupancy or compliance certificate has been issued for the building through the Balady platform, along with the presence of a valid latent defects insurance policy signed with the developer or contractor, or you can hire certified engineering inspection companies to inspect the property on-site.
The allowable building area is determined by what is known as the construction percentage and setbacks, where in standard residential villas, it is permitted to build two floors and an annex with a coverage ratio not exceeding sixty percent of the total land area, leaving the remaining space for regulatory setbacks and courtyards around the building.
