FOREWORD
The Standard TCXDVN 266:2002 is compiled on the basis of the Ordinance on
people with disabilities (PWD) :
Article 26.- “The investment for new construction or reconstruction of dwelling houses, of
public amenities and for design, manufacture of domestic furnitures, of transport and
communication means ... must take into account the needs for convenient use by PWD, firstly of
mobility and sight PWD, and at the same time have to comply with construction codes,
standards issued by competent state agencies”.
The Standard TCXDVN 266:2002 is compiled by the Research Institute for
Architecture and the panel for elaboration of “Codes and standards of
construction accessibility for people with disabilities in Vietnam”, submitted by
the Department of Science and Technology – Ministry of Construction, and
approved, signed, issued by the said ministry for enforcement.
The Standard TCXDVN 266 : 2002 is compiled with the cooperation and
funding by President’s Committee on Employment of People with Disabilities
(PCEPD) and Vietnam Assistance for the H andicapped (VNAH)

CONSTRUCTION STANDARD OF VIETNAM TCXDVN 266:2002
Residence - Guidance of accessible design and construction for people with disabilities (PWD)
1. Scope of application
This guidance is applied in the new construction of house/residence types ensuring the
accessibility and use by PWD in mobility and sight, and at the same time encouraged to

apply in the reconstruction/upgrade of old residential groups, taking into account the need
for use by PWD
2. Standards referred/cited
- Building code of construction accessibility for PWD
- TCVN 4451 :1987 - Residence - Basic rules for design
- TCXD 228 : 1998 - Walkway for PWD in facilities.
Part 1- Walkway for wheelchair users - Design requirements.
- TCXDVN 264 : 2002 - Buildings and facilities – Basic rules of accessible design
and construction for PWD.
3. Terminology, definition
Terminologies used in this guidance have been defined in the Building code of construction
accessibility for PWD.
4. Planning of residential quarter
4.1. The planning of residential construction for ensuring accessibility and use by PWD must
comply with the standard TCVN 4451:1987 - Residence - Basic rules for design.
4.2. Residences for ensuring accessibility and use by PWD are built at the following priority
locations:
- Locations convenient for transport, easily accessible by PWD;
- Locations close to parks, greenery, promenade ways;
- Locations close to commercial service centers, public service centers and health
care centers.
4.3. In residential quarters, it is necessary to design routes and sidewalks convenient for the use
of PWD. At entrance ways to residences, the sloping routes, sloping path to sidewalks for
PWD’s wheelchair must be arranged.
4.4. In residential quarters, signposts, guidance posters for PWD must be placed.
4.5. In designing residences for PWD, besides the compliance with requirements in this
guidance, designers must abide by regulations of the standard TCXDVN 264 : 2002 -
Buildings and facilities - Basic rules of accessible design and construction for PWD.
5. Design solutions
5.1. Car parking ground and car waiting spot

5.1.1. Car parking ground must comprise places for arranging PWD’s wheelchairs. The ratio of
places in car parking ground is as follows : for every 100 cars in general there must be 2
3 places for PWD’ vehicles. PWD’s vehicles must be arranged beside sloping way or at
the entry/exit path of buildings, with signpost, guidance poster, accordingly.
5.1.2. By the side of car parking ground there must be a clearance space for PWD on wheelchair
could ascend and get down. Width of clearance space: from 900mm to 1,200mm, in case
4
of bus, it must be 2,500mm (see fig. 1). But if it is arranged for two PWD’s to be parked
side by side, so it becomes possible to use a common path for wheelchairs.
5.1.3. At car waiting spots, sloping paths or sloping ways must be designed for PWP on
wheelchair could access to transport means. Car waiting spots must be lighted by at least
54 lux and have roofing. Details for design of sloping way, sloping path are in
accordance with regulations in article 5.2.

5.2. Sloping way
5.2.1. Entry/exit ways of residence for ensuring accessibility and use by PWD must not have
brusque change in elevation, if there exist elevation change, it is necessary to design
sloping way. Sloping way for ensuring the use by PWD must be plane, unrugged and
with roughness.
5.2.2. Sloping ways of main entrance reserved to PWD on wheelchair comprise:
- Permissible slope from 1/10 to 1/33. Height and length of sloping of way are
shown in table 1.
- Width of sloping way must not be less than 1000mm. See fig 2, 3, 4.
- Arrangement of landing where length of sloping way exceed 9,000mm Length of
landing must not be less than 2,000mm and spaced by equal intervals not
exceeding 9,000mm (see fig 5 and fig 6)
- At two sides of sloping way, handrails must be arranged. Details for design of

handrail are shown in article 5.12
Note:
1) Where sloping way changes direction, L-shaped landing must be arranged, with each
side 2,000mm long.
2) Where sloping way has a slope exceeding 1/33, no need for arranging landing.

5.2.3. At the extremity and the end of sloping way, it must be a void space for wheelchair could
move, with dimension not less than 1,500mm.
5.2.4. It is necessary to arrange balustrade, handrails on both sides of the sloping way. Where in
a side of sloping way there is a void space, then under the balustrade, the handrail, it is
advisable to arrange safety edge with a height not less than 50mm, or to set up fence, see
fig 7.

5.2.5. Sloping way for blind persons has auxiliary low balustrade, with direction guiding slab
and indicating where are summit of sloping way, landing, waiting spot.

5.3. Entry/exit way
5.3.1. In cases of residence where it is not possible to design sloping way, it is necessary to
design entry/exit way with steps for convenience to persons with difficult mobility such
as people on crutches, on stick and blind people. Entry/exit way with steps must ensure
following requirements :
- Permissible height of step : 120mm 160mm,
- Permissible width of step face : 250mm 400mm,
- Not using hollowed-out steps

- Arranging landing at highest step
- Where the stair comprises more than three steps, on two sides of the stair,
handrails must be arranged. Details for design of handrails are shown in article
5.12 (see fig. 8 and fig. 9)
Note : Regarding independently designed residences, it is permissible to design
hollowed out stair steps if so required.

of sloping way into house floor.
