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:

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

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)

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)

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.

4. Fire and Life Safety (SBC 801)

4.1 SBC 801-CR Structure

IBC/IFC-aligned. Key chapters:

• Ch. 4 General Building Heights and Areas (cross-ref SBC 201 Ch. 5)
• Ch. 5-9 Building Types and Specific Occupancies
• Ch. 10 Means of Egress (IBC Ch. 10 aligned)
• Ch. 11 Accessibility (overlap with Saudi Universal Accessibility Code)
• Ch. 14 Exterior Walls (NFPA 285 cladding alignment)
• Ch. 26-29 Fire-protection systems
• Ch. 33 Existing buildings
• Ch. 34 Special detailed requirements

4.2 Egress Travel Distances (SBC 801 Ch. 10)

Aligned to IBC Table 1017.2 with Saudi modifications:

4.3 High-Rise (SBC 801 Ch. 4 Special Detailed)

• Threshold: building > 23 m (75 ft) above lowest fire-department access
• Required: 2 enclosed exit stairs (pressurized in many cases), 2-hour fire-rated lobbies, sprinklers throughout, voice evacuation, fire command centre, fire lift complying with EN 81-72 equivalent
• Smoke control: required atrium, mall, underground parking, high-rise per SBC 801 Ch. 28

4.4 External Wall Cladding (SBC 801 Ch. 14, post-Mecca crane tower fires)

Aligned to IBC Section 1402-1406 and NFPA 285:

• Buildings > 18 m (60 ft) require NFPA 285 tested assembly OR Class A1/A2 non-combustible
• Storage building heat-released ban: large-scale combustible cladding effectively prohibited
• Approval: Civil Defence reviews + Saudi Standards (SASO) certification of products

4.5 Civil Defence Approval Pre-Design

For any major project (high-rise, hospital, school, hotel, mall, industrial, special hazards):

1. Concept submission to Civil Defence -- review of fire strategy
2. Design Development submission -- complete fire/life safety design package
3. Construction-phase inspections
4. Pre-occupancy inspection -- Civil Defence Completion Certificate required before Amana issues Occupancy Permit

5. Energy Code (SBC 601)

5.1 SBC 601-CR Structure

Aligned to IECC 2015 + ASHRAE 90.1-2013 with Saudi modifications. Mandatory.

Saudi Climate Zones (SBC 601-CR Section 301.1):

5.2 SBC 601 Prescriptive Envelope Targets

(Values indicative; refer to SBC 601-CR current edition tables.)

5.3 Mostadamah (Saudi Green Building Program)

Saudi's voluntary-tier green rating system. Categories: Site, Water, Energy, Materials, IEQ, Innovation. Pursued by government-funded projects and increasingly by private developers (NEOM, Red Sea Global require equivalent).

5.4 SEEC Programs
