Country: Kingdom of Saudi Arabia
Architectural code and regulatory reference for projects within Saudi Arabia. Activate this skill on any reference to Saudi cities (Riyadh, Jeddah, Mecca, Medina, Dammam, Tabuk, AlUla, NEOM, Khobar, Dhahran), SAR currency, "Amana"/"Baladiya", Royal Commission projects, Mostadamah, SBC codes, or Saudi Civil Defence (Difa'a al-Madani).
1. Regulatory Hierarchy
Saudi Arabia operates as Archetype A (Unitary National Code): the Saudi Building Code (SBC) is mandatory throughout the Kingdom for all new construction since 2018. Provincial variations are administrative (which Amana issues the permit), not technical.
1.1 Authority Stack
LEVEL 1 -- NATIONAL
Ministry of Municipal, Rural Affairs and Housing (MoMRAH) -- urban policy & code adoption
+ Saudi Building Code National Committee (SBCNC) -- publishes SBC series
Saudi Standards, Metrology and Quality Org (SASO) -- materials/products
Saudi Energy Efficiency Center (SEEC) -- energy programs
General Directorate of Civil Defence (Mudiriat al-Difa'a al-Madani) -- fire approvals
Authority of People with Disabilities -- accessibility policy
General Authority for Survey and Geospatial Information -- maps, coordinates
Saudi Authority for Industrial Cities & Technology Zones (MODON)
Royal Commission for Jubail and Yanbu (RCJY) -- separate jurisdiction
Royal Commission for AlUla (RCU) -- separate jurisdiction
NEOM -- separate regulatory framework
Qiddiya Investment Company -- separate regulatory framework
Red Sea Global -- separate regulatory framework
Diriyah Gate Development Authority -- separate regulatory framework
LEVEL 2 -- REGIONAL
Regional Council of each Emirate (Riyadh, Mecca, Medina, Eastern, Asir, Tabuk, Qassim,
Hail, Northern Borders, Jazan, Najran, Al-Bahah, Jouf) -- regional planning oversight
LEVEL 3 -- LOCAL (PERMITTING)
Amana / Baladiyah (Municipality) -- per city:
Riyadh: Amanat al-Riyadh (now under Royal Commission for Riyadh City - RCRC)
Jeddah: Amanat Jeddah
Mecca: Amanat al-Asimah al-Muqaddasah (Holy Capital Municipality)
Medina: Amanat al-Madinah al-Munawwarah
Dammam: Amanat al-Mintaqah al-Sharqiyah
+ Sub-municipalities (Baladiyah Far'iyah) for districts within metropolises
LEVEL 4 -- PROJECT
Civil Defence (Difa'a al-Madani) -- pre-design + occupancy NOC
Saudi Electricity Company (SEC) -- electrical sanction
National Water Co (NWC) / SWCC -- water/sewer
Ministry of Tourism -- hotel licensing
Ministry of Health -- hospital/clinic licensing
Ministry of Education -- school/university licensing
Ministry of Investment (MISA) -- foreign-owned projects
1.2 Giga-Project Special Jurisdictions
Vision 2030 has spawned several non-Amana jurisdictions with their own building authorities:
| Giga-Project | Authority | Code Approach |
|---|
| NEOM | NEOM Company (own urban authority) | NEOM Building Code in development; in interim, project-specific authority approval; reportedly aligned to SBC + Eurocodes + bespoke high-performance overlay |
| The Line | NEOM | Special structural performance criteria (200 m height, 170 km length) |
| Qiddiya | Qiddiya Investment Company | Qiddiya Design Guidelines + SBC overlay |
| Red Sea / AMAALA | Red Sea Global | Red Sea Sustainability Standards (target LEED Platinum equivalent) + SBC + bespoke coastal-eco overlay |
| Diriyah | Diriyah Gate Development Authority | Salmani Architecture Guidelines (Najdi vernacular + modern); UNESCO heritage area compliance |
| AlUla | Royal Commission for AlUla (RCU) | RCU Master Plan + Heritage Conservation Code; UNESCO World Heritage Hegra restrictions |
| King Salman International Airport (KSIA Riyadh) | RCRC + GACA | Aviation code overlay |
| King Abdullah Economic City (KAEC) | Emaar the Economic City | KAEC Guidelines + SBC |
| Jubail Industrial City | RCJY | RCJY-specific industrial codes + SBC |
| Yanbu Industrial City | RCJY | Same |
In any of these, project teams must follow the specific authority's design guidelines AND the SBC -- the giga-project guidelines layer on top, not replace.
1.3 Sacred City Restrictions (Mecca + Medina)
- Mecca and Medina: only Muslims may permanently reside/work; non-Muslim consultants typically work via Saudi-Arabia-licensed Saudi associates with offsite review
- Both cities have special height limits in zones surrounding the Two Holy Mosques (Masjid al-Haram, Al-Masjid an-Nabawi) -- elevations, materials, colors, signage all controlled by Royal Commission for Mecca/Medina + Saudi Heritage Authority
- Hajj building regulations -- special crowd-flow requirements for hotels and infrastructure on the Hajj routes; capacity calculations follow Hajj Research Institute methodologies
2. Saudi Building Code Structure
The Saudi Building Code (SBC) was first published in 2007 with major revision in 2018 -- the 2018 edition is the operative version (with periodic updates issued by SBCNC). All buildings nationally must comply.
2.1 Nine-Part Structure
| Code | Title | Aligned to / Derived From |
|---|
| SBC 201-CR | General Building Requirements | IBC 2018 |
| SBC 301-CR | Structural - Loads | ASCE 7-16 |
| SBC 302-CR | Concrete | ACI 318-14 |
| SBC 303-CR | Foundations / Soil Mechanics | -- |
| SBC 304-CR | (Note: numbering varies by edition; check current) | -- |
| SBC 305-CR | Masonry | TMS 402/602 |
| SBC 306-CR | Steel | AISC 360 |
| SBC 307-CR | Composite | AISC 360 + AISI |
| SBC 401-CR | Electrical | NEC 2017 (NFPA 70) |
| SBC 501-CR | Mechanical | IMC 2018 |
| SBC 601-CR | Energy Conservation | IECC 2015 + ASHRAE 90.1-2013 base, with SBC modifications |
| SBC 701-CR | Plumbing | IPC 2018 |
| SBC 801-CR | Fire | IFC 2018 + NFPA cross-references |
| SBC 901-CR | Existing Buildings | IEBC 2018 |
| SBC 1001-CR | Green Buildings | LEED + ASHRAE 189.1 + IgCC |
SBC-G (general public) and SBC-CR (technical/engineer) are the two reading tiers. Practitioners use SBC-CR.
2.2 Adoption Year by City
While SBC is technically nationally mandatory since 2018, enforcement strength varies:
- Riyadh, Jeddah, Dammam, Mecca, Medina: full SBC enforcement at Amana level since 2019
- Tier-2 cities: enforcement strengthening 2020-2024
- Tier-3 / rural: SBC formally applies but on-site practice may lag
- Giga-projects: own authority + SBC overlay
3. Building Code Core (SBC 201 + 801)
3.1 Occupancy Classification (SBC 201 Ch. 3, IBC-aligned)
| Group | Occupancy | Subdivisions |
|---|
| A | Assembly | A-1 (theaters), A-2 (food/drink), A-3 (worship/exhibit), A-4 (indoor sport), A-5 (outdoor) |
| B | Business | -- |
| E | Educational | up to 12th grade |
| F | Factory/Industrial | F-1 moderate, F-2 low hazard |
| H | High Hazard | H-1 to H-5 |
| I | Institutional | I-1 supervised; I-2 medical care; I-3 detention; I-4 day care |
| M | Mercantile | -- |
| R | Residential | R-1 transient, R-2 apartment, R-3 single-family, R-4 small care |
| S | Storage | S-1 moderate, S-2 low |
| U | Utility | -- |
3.2 Height & Area (SBC 201 Ch. 5 + Table 504)
IBC-aligned; same Type IA through VB construction types; same height-vs-area-vs-occupancy-vs-construction matrix.
Key Saudi-specific note: Saudi practice often uses Type IA or IB (fully fire-protected) for most large buildings due to fire policy + insurance.
3.3 Setback and FAR -- Riyadh Example (RCRC)
| Zone | FAR (sometimes "Floor Area Coefficient") | Coverage | Setbacks | Height |
|---|
| R1 villa | 1.0-1.5 | 50% | 5 m front, 3 m sides | 12 m (2-3 floors typical) |
| R2 (apartments) | 2.5-4.0 | 50-60% | 5-7 m front, 3-5 m sides | 20-30 m |
| Commercial mid-density | 4.0-6.0 | 70% | per street width formula | 30-45 m |
| Commercial high-density / CBD | 6-12 | 70-80% | per zoning + setback minimum 5 m | 100 m+ (per skyline plan) |
| Industrial | 0.8 | 50% | 8 m front | varies |
Riyadh's Riyadh Strategic Plan 2030 + King Salman Renaissance Project (RCRC) are restructuring zoning. Confirm current Detailed Land Use Plan (DLUP) for any specific plot.
3.4 Setback and FAR -- Jeddah
Jeddah's coastal high-density mid-rise pattern uses Building Coefficient = FAR × site coverage. Old city (Al-Balad UNESCO heritage zone) has strict conservation rules.

7.4 Soils
Saudi has problematic soils in many regions:
- Sabkha (coastal salt flats around Persian Gulf, Red Sea): high sulphate + chloride, weak bearing
- Gypsum-bearing soils (Riyadh, Eastern Province): solubility risk
- Calcareous soils (coastal): variable strength
- Expansive clays (some Eastern + Northern areas)
Sulphate-resistant cement per SASO/SBC 302 mandatory for coastal foundations.
8. Construction Permits Workflow
8.1 Steps (Riyadh as representative)
- Land documentation: Saqq (Title Deed) verification with Ministry of Justice
- Survey + soil report by certified office
- Concept design + plot certificate (Maska al-Aradhi) check
- Schematic submission to Amana (Belady portal in Riyadh) + Civil Defence pre-approval
- Detailed Design submission -- structural calculations, MEP, fire engineering report, accessibility, energy compliance per SBC 601
- Building Permit issuance by Amana
- Construction supervision contract mandatory -- consultant signs off on phases
- Milestone inspections -- foundation, structure, MEP, completion
- Pre-occupancy inspections -- Civil Defence + Amana
- Occupancy Certificate (Shahadat Itham al-Bina'a) by Amana
- Utility connections SEC + NWC + others
8.2 Special Workflows
- Giga-projects: own authority handles steps 4-10 internally; SBC compliance reviewed by their consultants
- Royal Commission projects (RCJY, RCU, RCRC): separate workflow within commission's design + permit office
- Mecca/Medina holy precincts: additional Royal Commission approval; restrictions on construction during Hajj season (~6 weeks)
