11.2. Legal and Regulatory Framework in India

Part 3 of the NBC 2016 focuses on Development Control Rules and General Building Requirements, including the “Guidelines and Space Standards for Barrier-Free Built Environment for Disabled and Elderly Persons”.

The National Building Code (NBC) of India is a crucial document that outlines regulations and standards that must be followed when constructing buildings. Part 3 specifically addresses the need for creating spaces that are accessible to everyone, especially focusing on disabled and elderly persons. The guidelines emphasize the physical aspects of buildings, such as the dimensions and types of facilities that must be included to ensure ease of access.

Think of the NBC like a recipe book for making a cake. Just as a recipe outlines the specific ingredients and steps necessary to bake a cake properly, the NBC provides precise guidelines on how to construct buildings that everyone can use comfortably.

• Access Routes: – Minimum clear width: 1200 mm. – Slope: Not more than 1:12 for ramps. – Handrails on both sides of ramps and stairs.

• Parking: – Designated accessible parking spaces near entrances. – Size: Minimum 3600 mm × 5000 mm.

• Entrances and Doors: – Minimum clear opening of 900 mm. – Level landing in front of doors.

• Lifts: – Audible and visual signals for floor indication. – Braille markings on control panels. – Minimum size: 1100 mm × 1400 mm (for wheelchair users).

This chunk breaks down the key features that the NBC specifies for accessibility in the built environment. Access routes must be sufficiently wide and have manageable slopes to allow wheelchair users easy movement. Designated parking spaces are required to be available close to entrances to facilitate quick access. Entrances and doors need to have minimum widths to accommodate wheelchairs, and there must be clear space in front of doors. Additionally, it is essential for lifts to have both auditory and visual signals, as well as Braille, to assist people with hearing or visual impairments.

Imagine trying to enter a store with your shopping cart. If the entrance is too narrow or there is a steep ramp, it would be difficult or impossible to get inside. The NBC's requirements ensure that everyone, regardless of their mobility needs, can easily and safely access buildings.

• Sanitary Facilities: – Accessible toilets with minimum dimensions of 2200 mm × 1500 mm. – Grab bars, lever-handled taps, and non-slip flooring.

• Signage: – Visual, tactile, and auditory signage. – High contrast colors and symbols for easy readability.

This chunk outlines requirements for sanitary facilities and signage within public buildings. Sanitary facilities need to be spacious enough to accommodate support equipment for users with disabilities, such as grab bars to assist in transferring from wheelchairs. The surfaces must also be safe to prevent slipping. Signage must be created to serve everyone, using visual, tactile (like Braille), and auditory formats to cater different user needs, with high contrast to ensure visibility and readability.

Think about navigating an airport. You need clear signs that not only tell you where to go but do so in a way that everyone can understand—whether it's through written words, symbols, or auditory announcements. This is similar to how effective signage in public spaces helps everyone find their way without difficulty.

MoHUA has developed the “Harmonised Guidelines and Standards for Universal Accessibility in India”, revised in 2021, which supplement the NBC and detail how to implement universal accessibility in urban built environments.

The Ministry of Housing and Urban Affairs (MoHUA) created supplementary guidelines to the NBC to provide specific, actionable steps for implementing universal accessibility. These guidelines were revised to adapt to evolving needs and frameworks, specifying how urban environments can be made accessible, from buildings like schools and hospitals to public transport systems.

Consider the MoHUA guidelines as a set of instructions that go into more detail than the earlier recipe. If the NBC is the basic recipe, then the MoHUA guidelines are like the notes a chef adds to improve the dish based on customer feedback—making the process clearer and better for everyone involved.

• Universal Design across all buildings: schools, hospitals, government offices, public toilets, and recreational spaces.

• Accessible Urban Streets: Guidelines for tactile pavers, kerb ramps, and barrier-free pedestrian crossings.

• Inclusive Public Transport Infrastructure: Low-floor buses, audible stop announcements, and accessible metro stations.

MoHUA's guidelines encompass several key areas, focusing on universal design principles for all types of urban buildings and infrastructure. This includes creating accessible streets with features like tactile paving for visually impaired individuals and ensuring public transport is user-friendly, such as low-floor buses that are easier for individuals with mobility issues to board.

Imagine trying to navigate a city with a stroller. If there are no ramps or elevators, it makes the experience very difficult. The MoHUA guidelines ensure that all urban designs consider various needs, much like ensuring that streets are user-friendly not just for cars, but for everyone travelling in different ways.
