What affected residents need to know
About 80 residents from 45 Block D units were ordered out as a precaution. Re-entry depends on the technical safety assessment now being prepared by JKR, JPS, JMG and MPKj; the cause has not been officially confirmed.
01 · The latest position
Residents from Block D of Damai Perdana Apartments in Bandar Damai Perdana, Cheras remain subject to the evacuation while authorities assess whether the building and adjacent slope are safe for occupation. Kajang Municipal Council Zone 6 councillor Tan Kah Hoe said on 24 September 2026 that the technical assessment was continuing and a full report was expected within the next few days.
The assessment involves the Public Works Department (JKR), Department of Irrigation and Drainage (JPS), Minerals and Geoscience Department (JMG) and MPKj. Until that report is completed, residents should not interpret a quiet slope or restored utilities as clearance to re-enter evacuated units.
02 · Who was evacuated
About 80 residents from 45 units in Block D were ordered to leave immediately on the evening of Tuesday, 22 September as a safety precaution. By 23 September, 15 local families were staying at the temporary relief centre at the Desa Baiduri community hall, up from four families initially; others were staying with relatives.
The Social Welfare Department is managing accommodation and food for affected residents, while police are assisting with security at evacuated homes. No injuries were reported in the available official and mainstream reports reviewed for this update.
03 · What happened on the hillside
The incident involved a slope beside Block D. Early fire-and-rescue reporting described a collapsed section of hillside and continuing water flow at the site. Authorities then ordered the evacuation and began stabilisation and inspection work.
A leaking underground pipe has been raised as a possible cause, and residents reported heavy water flow before the slope failed. However, MPKj has said the investigation is still considering that possibility. It should not be treated as the confirmed cause until the technical report is released.
04 · Water supply and the apartment blocks
The Damai Perdana apartment complex has four blocks and about 360 residential units. On the morning of 24 September, water supply had been restored to Blocks A and B. Block D remained without water, while restoration to Block C was taking longer because authorities were tracing the affected pipeline route.
Those utility updates matter for daily life, but they are separate from the structural-safety decision. The key trigger for residents of evacuated Block D units is the formal technical assessment, not simply the return of water or access elsewhere in the complex.
05 · What the authorities are checking
The joint assessment is looking at the safety of the building and slope as well as the cause of the failure. JKR is involved in the structural/engineering assessment; JMG is assessing geological and slope conditions; JPS is part of the current multi-agency review; and MPKj is coordinating local action.
RTM reported on 23 September that the management body was also checking insurance coverage for slope failure. Any repair liability, insurance position or long-term engineering solution remains a separate issue from the immediate question of whether residents can safely return.
06 · What residents should do now
Residents covered by the evacuation should continue to follow MPKj, JKR and on-site emergency instructions and wait for explicit clearance before returning to affected units. People collecting medicines, documents or other essentials should use whatever controlled-access process the authorities or building management provide rather than assume access is unrestricted.
For neighbours and visitors, the practical message is to keep clear of the affected slope and emergency-work area. Conditions can change while geotechnical and structural checks are under way, and photos or social-media posts are not a substitute for an official safety decision.
07 · What we know — and what remains uncertain
The confirmed position is that a landslide occurred beside the apartment complex, about 80 residents from 45 Block D units were evacuated, a temporary relief centre was opened, and a multi-agency technical assessment is under way. Authorities expect the report within days rather than weeks, although no exact release time has been guaranteed.
The cause remains under investigation. Reports have repeatedly mentioned a suspected pipe leak, but the available evidence does not justify presenting that theory as settled fact. The duration of the evacuation will depend on the structural-safety findings and any repairs or risk controls they require.
08 · Sources & verification
This report is based on The Star’s 24 September update on the structural-safety assessment, RTM’s 23 September report on the investigation and evacuation, and Malay Mail’s 24 September update on displaced families and agency work.
We have deliberately described the pipe leak only as a possible cause because the technical investigation is not complete. We will treat the safety report, any formal re-entry order and any confirmed cause as later developments rather than speculate ahead of the agencies.
