SBC isn't one document, it's 13 volumes covering architecture, structure, electrical, mechanical, fire, energy, plumbing, gas, and more. Most engineers know SBC 401 (electrical) and SBC 801 (fire). Here's the full map and which volume governs what.
Four ideas to carry into the next specification conversation you have.
From SBC 201 (architectural) to SBC 1001 (existing buildings), adopted from ICC base codes with Saudi-specific amendments.
Based on IEC standards. Covers wiring, distribution, protection, earthing, control of installations.
Based on NFPA 101. KSA Civil Defense uses it for occupancy certification. Mandatory citation in every Saudi tender.
Saudi Building Code National Committee (NHC) publishes English + Arabic versions. Reference clauses by SBC number + volume number + section.
Current version: SBC 2018 + amendments. Saudi Building Code National Committee (NHC).
| Volume | Topic | Base reference |
|---|---|---|
| SBC 201 | General Architectural Code | IBC |

| SBC 401 | Electrical Code | IEC + NEC influence |
| SBC 501 | Mechanical Code (HVAC) | ICC IMC |
| SBC 601 | Energy Conservation Code | ASHRAE 90.1 |
| SBC 701 | Plumbing Code | ICC IPC |
| SBC 801 | Fire & Life Safety Code | NFPA 101 |
| SBC 901 | Gas Code | ICC IFGC |
| SBC 1001 | Existing Buildings Code | ICC IEBC |
| SBC 1101 | Residential Code | IRC |
| SBC 1201 | Green Buildings Code | Mostadam-aligned |
| SBC 1301 | Saudi Code for Earthquake-Resistant Design | Saudi-specific seismic |
| SBC 1401 | Soil Investigations | Saudi geotechnical |
Five tips that save hours when researching Saudi compliance.
Wrong: 'per Section 12.4'. Right: 'per SBC 401-2018, Section 12.4'. The number 12.4 means different things across volumes. Full citations survive code revisions and reviewer changes.
SBC 401 ≈ IEC 60364 + select NEC. SBC 801 ≈ NFPA 101 with Saudi amendments. When SBC is silent on a topic, refer to the base. Reviewers expect this.
SBC 401 has Saudi-specific amendments, for example, derating tables that account for 50 °C ambient. Where SBC differs from IEC, SBC wins. Always read the amendments section of each volume first.
SBC 401 says one thing about emergency lighting circuits. SBC 801 says something else. The conflict resolution is in Section 1 of each volume, usually the more restrictive interpretation governs.
Download from sbc.gov.sa. Cite as 'Saudi Building Code Council, SBC 401-2018, Chapter X, Section X.X'. For tender clarification, attach the relevant page screenshot, reviewers won't open the PDF.
Every NLC submittal includes an SBC compliance matrix, citing exact clauses for cable sizing, protection, earthing, and fire-rated separations. Saves consultant review time.
