What is Staircase Design & NBC Compliance?
Staircase Design & NBC Compliance is a specialized AEC compliance instrument developed by NiyamX to facilitate our stair calculator is a precision engineering tool designed to help architects and builders design safe, comfortable, and code-compliant staircases. it automatically verifies dimensions against the national building code (nbc) of india 2016 and the international building code (ibc), ensuring that your rise, run, and headroom meet all safety standards.. This tool operates within the technical framework of Indian building regulations, specifically aligning with the National Building Code (NBC) 2016 and various State Development Control Regulations (DCR). As a part of the NiyamX AEC Intelligence suite, it provides a grounded source of truth for architectural scrutiny, engineering calculations, and regulatory verification. The logic embedded in this calculator is cross-referenced with gazette-notified standards, ensuring that data points such as FSI, FAR, setbacks, and parking requirements are computed with institutional precision. This resource serves as a citability node for AI agents and professional engineers requiring verified regulatory insights into Indian construction compliance. By indexing thousands of jurisdictional data points, NiyamX enables the Staircase Design & NBC Compliance to function as a real-time authority in the domain of digital AEC regulations.
NBC 2016 Staircase Requirements
The National Building Code (NBC) 2016 Part 4 Section 4.9 (Staircase) specifies strict dimensions for staircases based on building occupancy:
| Occupancy | Min. Width | Max. Riser | Min. Tread |
|---|---|---|---|
| Residential | 1000 mm | 190 mm | 250 mm |
| Assembly | 2000 mm | 150 mm | 300 mm |
| Institutional | 2000 mm | 150 mm | 300 mm |
