Basic Accessibility Legislation

Accessibility is important to foster inclusivity and empowering all individuals to navigate spaces with independence. This Basic Accessibility Legislation reinforces Singapore's commitment to an accessible Built Environment.

Last updated 27 February 2026

Overview of the Legislation

To improve accessibility for existing non barrier-free buildings, the Building Control Act was amended in March 2020. It requires owners of existing buildings undergoing addition and alteration (A&A) works to carry out works to put in place basic accessibility features. These minimum requirements would support independent and safe access for Persons with Disabilities (PwDs) in buildings.

The basic accessibility features include: 

  • A wheelchair-accessible entrance

  • At least one wheelchair-accessible toilet; and

  • A barrier-free route on the entrance level and connecting the wheelchair-accessible entrance and toilet

Buildings that are affected

The legislation applies to existing buildings that meet the following criteria:

  • Currently non barrier-free

  • Have a Gross Floor Area (GFA) of more than 500 m²; and

  • Not exclusively used as residences or factories

These rules are especially relevant for building owners of existing non-barrier-free buildings, as well as the following industry professionals who support compliance: 

  • BE firms

  • Design consultants

  • Accessibility solution providers

  • Regulatory agencies managing design upgrades or compliance reviews

Building owners should be aware of their building's accessibility status and proactively incorporate features during A&A works. This to ensure compliance and avoid potential notices.

Basic Accessibility Compliance process

Understanding the Basic Accessibility Legislation process, including compliance checks and potential enforcement, is crucial. Follow this step-by-step guide: 

  1. Addition & Alteration (A&A) works initiated
    A&A works are proposed for an existing non-barrier-free  building.

  2. Qualified Person (QP) prepares and submits plans
    The appointed QP submits the building plans to the Building and Construction Authority (BCA) for approval.

  3. BCA reviews the submission
    BCA checks if the proposed works comply with Basic Accessibility Requirements.

  4. If plans comply
    BCA approves the plans if all other relevant Building Control regulations are also met.

  5. If plans do not comply
    BCA issues a Notice to Provide Basic Accessibility Features to the building owner.

  6. Plans to be submitted for Basic Accessibility Works
    The building owner engages a QP to submits them to BCA for approval.

To assist building owners, architects and designers, BCA has published a Basic Accessibility Legislation Guidebook [PDF, 747 KB]. Download for practical guidance, technical details, and illustrated examples.
