In Singapore, “barrier-free accessibility code” refers to the Code on Accessibility in the Built Environment 2025, issued by the Building and Construction Authority (BCA). The Code took effect on November 1, 2025, and applies to all new building works and to existing buildings with plans submitted for Addition and Alteration (A&A) works on or after that date.
TL;DR:
- Buildings must connect seamlessly to surrounding transit infrastructure, not just within the building, as part of the barrier-free interconnectivity requirement.
- Full compliance is mandatory for all new buildings and for existing buildings over 500 square meters GFA undergoing A&A work, excluding private residences and factories below this threshold.
- Mandatory features include a continuous barrier-free route, at least one accessible toilet on the main circulation path, and lifts at changes in level that ramps cannot serve.
- Early coordination among architects, engineers, and Qualified Persons on route diagrams and lift specifications reduces plan review delays and costly late adjustments.
- Referencing the Companion Guide explicitly in design notes, and mapping external accessibility routes before finalizing entrances, speeds up approval and minimizes resubmissions.

Key requirements and what changed in Code 2026
Code 2025 is the sixth revision since the original standard was introduced in 1990, and it shifts the framing from basic accessibility toward genuine inclusion. The BCA newsroom announcement describes several headline upgrades that project teams now need to design around from the earliest concept stage.
- Barrier-free interconnectivity: buildings must connect more seamlessly to surrounding infrastructure, including MRT stations, park connectors, and covered walkways, rather than treating accessibility as an isolated, building-only concern.
- Accessible entrances: primary entrance points receive tighter requirements to make sure wheelchair users and people with mobility aids reach a building without detours.
- Enhanced lift provisions: lift specifications were raised to support a broader range of mobility devices and reduce bottlenecks at peak hours.
Barrier-free interconnectivity is the most significant conceptual shift in this revision. Where earlier codes focused on what happens inside the building line, Code 2025 asks architects and engineers to account for the barrier-free route beyond the site, linking building entrances to nearby transit nodes and public paths. Some clarifications in the Code also streamline design decisions that previously caused ambiguity during plan review, reducing back-and-forth between QPs and BCA assessors.
Who and when the Code applies
Code 2025 distinguishes between new building works, which must comply in full regardless of size, and Addition and Alteration (A&A) works on existing buildings, which trigger compliance obligations only under specific conditions.
- New building works: full compliance with Code 2025 is mandatory for every new development, with no size exemption.
- A&A works on existing non-barrier-free buildings: compliance is triggered when the building has a gross floor area (GFA) above 500 square meters and is not used exclusively as a private residence or factory, according to BCA’s basic accessibility legislation.
- Exclusions: private residences and factory buildings below the threshold generally fall outside the mandatory trigger, though owners may still choose to upgrade voluntarily.
The effective-date rule matters for timing: provisions apply to plans submitted to BCA on or after November 1, 2025, so projects with plans lodged before that date follow the prior code version unless resubmitted.
Mandatory features and minimum design specs
For buildings that fall under the Code, a handful of physical elements form the baseline that every submission must demonstrate. These are the items BCA reviewers check first, and gaps here are the most common reason plans get returned.
- Accessible entrance and continuous route: every building needs a wheelchair-accessible entrance connected by an unbroken barrier-free route to the nearest public transport node or amenity, consistent with the interconnectivity principle in Code 2025.
- Wheelchair-accessible toilets: at least one accessible toilet is required, positioned along the main circulation path rather than tucked into a remote corner that adds unnecessary travel distance.
- Route widths and ramp gradients: clear widths along barrier-free routes and ramp gradients must meet the Code’s minimum dimensions, which govern how tight a corridor or incline can be before it stops qualifying as accessible.
- Lift requirements: lifts are mandatory wherever a barrier-free route crosses a change in level that a ramp cannot reasonably serve, and Code 2025 raises the bar on lift car dimensions and controls.
- Sheltered route priority: where a barrier-free route runs outdoors, it should align with existing covered walkways and external shelter rather than exposing users to weather along an otherwise compliant path.
Pro Tip: Map the barrier-free route on the site plan before finalizing entrance locations: moving an entrance a few meters late in design is far cheaper than discovering a shelter gap during BCA review.
Compliance process: submissions, QP role, and enforcement
A Qualified Person bears direct responsibility for demonstrating Code 2025 compliance in every submission to BCA, and that responsibility starts well before drawings are finalized. Our regulatory compliance guidance for architects covers the broader submission landscape that accessibility sits within.
- QP coordination: the QP should confirm barrier-free route continuity, toilet placement, and lift specifications with the architect and M&E engineer before the plan package is assembled, not after a first review flags it.
- BCA plan review: assessors check entrance accessibility, route widths, toilet locations, and lift provisions against Code 2025 minimums, and incomplete route diagrams are among the most common causes of returns.
- Notice to Provide Basic Accessibility Features: for existing non-barrier-free buildings meeting the GFA and use criteria, BCA guidance confirms that an accessible entrance, at least one accessible toilet, and a barrier-free route become mandatory once A&A plans are submitted.
Practical design guidance from the Companion Guide and Universal Design Index
The Companion Guide to Code on Accessibility 2025 sits alongside the mandatory Code as a non-mandatory reference, offering illustrated examples and recommendations that go beyond the baseline. Treating the two documents as separate tracks helps avoid confusion during design review.
- Mandatory versus recommended: the Code sets the minimum legal standard, while the Companion Guide suggests how to exceed it through better sightlines, tactile cues, and generous turning spaces.
- Common solutions: Companion Guide examples, such as additional handrail continuity at direction changes, frequently prevent the clarification requests that slow down otherwise compliant submissions.
- Documentation habits: referencing Companion Guide recommendations directly in drawing notes and design narratives gives BCA reviewers visible evidence of intent, which speeds up assessment.
Pro Tip: Cite the specific Companion Guide recommendation in your drawing notes rather than describing the feature generically: reviewers respond faster when the design intent is traceable to a named reference.
Public-facing accessibility data and mapping
BCA’s partnership with Google Maps and maps.gov.sg publishes building-level data on family and wheelchair-friendly features so the public can plan visits in advance.
- Facilities shown: accessible washrooms, hearing enhancement systems, and lactation facilities appear on the map alongside standard building listings.
- Owner responsibility: building owners benefit from keeping facility information current, since outdated listings undermine the purpose of the initiative and frustrate visitors who rely on it.
- Visibility benefit: a building that accurately lists its accessible amenities gains a practical advantage for visitors planning mobility-dependent trips, including the measurement and planning habits covered in this showflat checklist resource.
Practical checklist for Qualified Persons and building owners
Before a submission reaches BCA, running through a short sequence catches most of the issues that otherwise trigger a return.
- Confirm the trigger: verify whether the project is new building works or A&A works, and if A&A, check the GFA and use-type criteria against the basic accessibility legislation.
- Prepare route diagrams: include a dedicated barrier-free route diagram showing connections to the nearest transit node, with toilet locations and shelter continuity marked clearly.
- Coordinate disciplines early: have the architect, structural engineer, and M&E engineer confirm lift dimensions, ramp gradients, and entrance levels against each other before the QP compiles the package.
- Sequence for timing: integrate accessibility decisions at concept design rather than retrofitting them after structural layouts are locked, since late changes to entrance or lift locations carry outsized cost.
Pro Tip: Build a brief internal sign-off between disciplines before the QP submits: a short checklist meeting at concept stage is far cheaper than an amendment cycle after BCA review. Our architecture planning guide walks through this coordination sequence in more detail.
A practitioner’s view on early coordination
We have seen that projects coordinating accessibility requirements at concept stage, rather than treating them as a late checklist item, submit cleaner packages and face fewer amendment cycles. The barrier-free interconnectivity requirement in particular rewards teams that map external connections before finalizing entrance positions. This single habit, confirming the route to the nearest transit node before the floor plan is locked, consistently separates a smooth BCA review from a repeated one.

FAQ
What is the Singapore accessibility Code?
The Singapore accessibility Code is the Code on Accessibility in the Built Environment, issued by BCA, setting mandatory minimum standards for barrier-free design. The current version, Code 2025, took effect on November 1, 2025, and governs new buildings and qualifying A&A works.
What is barrier-free accessibility?
Barrier-free accessibility describes a built environment that people with disabilities, mobility aids, or other access needs can navigate without physical obstruction, through features like accessible entrances, ramps, and accessible toilets. Code 2025 extends this concept beyond the building line to interconnectivity with surrounding transit and public infrastructure, as described in BCA’s newsroom release.
What is a barrier free ADA unit?
The Americans with Disabilities Act (ADA) is a United States framework and does not apply in Singapore. Singapore projects instead follow the Code on Accessibility in the Built Environment, which sets its own requirements for accessible entrances, toilets, and routes under BCA’s jurisdiction.
How do I code for accessibility in a Singapore project?
Designing for accessibility means mapping a continuous barrier-free route from the building entrance to nearby transport and amenities, then confirming toilet placement, ramp gradients, and lift specifications meet Code 2025 minimums. Coordinating these decisions with a Qualified Person before submission, drawing on resources like the Companion Guide, reduces the chance of a plan return.
When do existing buildings need to comply with Code 2026?
Existing non-barrier-free buildings must include basic accessibility features, an accessible entrance, at least one accessible toilet, and a barrier-free route, once they submit A&A plans, provided the building exceeds 500 square meters GFA and is not used exclusively as a residence or factory, under BCA’s basic accessibility legislation.
