This guide is general information, not a substitute for a professional building inspection. For significant purchases, engage a qualified building inspector or structural engineer.
Sub-sale vs new property: why inspection differs
The legal implications of a property inspection are fundamentally different for sub-sale and new properties:
| Factor | Sub-sale property | New property (at VP) |
|---|
| Defect protection | None — caveat emptor (buyer beware) applies; no DLP | 24-month DLP from VP under Housing Development Act (Act 118) |
| When to inspect | Before signing SPA and before completing purchase | Before signing VP acceptance form |
| Leverage | Price negotiation or walk away | Force developer to rectify at no cost |
| Outcome if defects found | Negotiate price reduction or request remediation before completion | Submit formal defect list to developer within DLP (24 months from VP) |
| Professional inspector needed? | Strongly recommended for older properties | Recommended — developers prefer buyers who inspect thoroughly early |
For sub-sale properties, there is no statutory safety net: once you take vacant possession, every defect is your responsibility. Do not skip or rush the inspection.
Before you go: what to bring
- Torch (inspect dark corners, under sinks, inside wardrobes)
- Coin or small hammer for tapping tiles to detect hollow spots
- Phone for photos and video — document everything
- Moisture meter (or hire a professional who has one)
- Checklist (use the room-by-room list below)
- Spirit level — useful for checking floor gradient and surface flatness
- Bring someone who is handy or has renovation experience if you are unfamiliar with building defects
Inspect during daylight hours and ideally after a recent rainstorm — roof leaks, seepage stains and drainage problems show up most clearly when wet.
Structural checks
Structural defects are the most serious and expensive to rectify. Look for:
| What to check | What to look for | Risk level |
|---|
| Walls (internal + external) | Diagonal or step cracks (especially at corners and openings); cracks wider than 1–2 mm; cracks that have been patched or painted over | High if structural; lower if settlement-only |
| Floors | Uneven surfaces; hollow tiles (tap with coin); visible cracks; sloping visible to the eye | Medium — could indicate subsidence |
| Beams and columns | Spalling concrete; exposed rebar (corrosion); horizontal cracks on beams | High — engage structural engineer |
| Roof (if accessible) | Damaged or missing tiles; rust staining; cracked ridge capping; sagging | High — direct leak risk |
| Extensions and additions | Any non-original structure with no approval or DBKL/local authority endorsement | Medium — legal and insurance risk |
Waterproofing & water damage
Water damage is the most common and most expensive defect found in Malaysian properties. Signs include:
- Ceiling stains: Yellow-brown stains or paint bubbling on ceilings indicate water ingress from above — from the unit above (strata), the roof or the slab.
- Wet or damp walls: Efflorescence (white mineral deposits), paint peeling or greenish mould growth indicates persistent moisture in the wall cavity.
- Bathroom floors: Hollow tiles (tap with coin) indicate de-bonding caused by water under the screed. Cracked grout or silicone lines allow water penetration to the slab below.
- Basement car park or ground floor: Check for active seeping from expansion joints, damp walls, rust staining from reinforcement bars.
- Air-well and light well: These are common leak points in landed homes; check surrounding walls for damp patches.
- Kitchen wet zone: Check under the kitchen sink cabinet for moisture, swelling, mould or rust on cabinet board.
Any evidence of chronic water damage warrants a professional waterproofing assessment before you commit. See our ceiling leak guide → for cost context.
Electrical & plumbing checks
- Switchboard / Distribution Board (DB): Is it clearly labelled? Are circuit breakers the correct type and size? Old round pin or rewirable fuse boxes are a sign the wiring may be outdated and unsafe.
- Sockets and switches: Test every socket with a phone charger. Flickering lights or dead sockets indicate wiring issues.
- Water pressure: Run all taps simultaneously — pressure should be consistent. Low pressure may indicate blocked pipes or mains issues.
- Hot water: Test all water heaters. Instant heaters (for showers) and storage heaters (if any) should heat promptly without tripping the MCB.
- Drainage: Run taps in all sinks and bathtubs and watch drain speed. Slow drainage or gurgling sounds indicate partial blockages.
- Flush all toilets and confirm the cistern refills and seals properly.
- Water meter: Turn off all taps and check if the meter continues to tick — a running meter with everything off indicates a hidden pipe leak.
Finishes & fittings
- Doors and windows: Open and close every door and window. They should operate smoothly without binding or gaps at the frame. Check that locks work and keys are provided.
- Tiles: Tap all floor and wall tiles with a coin. Hollow sound = de-bonded tile. Check grout lines for cracks.
- Built-in carpentry: Open all cabinet doors and drawers. Check for warped panels, broken hinges, missing handles. Moisture-swollen cabinet boards in wet areas indicate past or present leaks.
- Ceiling and false ceiling: Look for water stains, sagging panels, rust marks at column bolt-holes (indicates moisture in the false ceiling void).
- Paintwork: Freshly painted surfaces can conceal cracks or stains. Look for textural irregularities and run a torch at low angle across walls to reveal patched repairs.
Room-by-room checklist
| Area | Key checks |
|---|
| Living & dining room | Floor tiles hollow check; ceiling stains; power points working; window locks functioning |
| Kitchen | Cabinet moisture / swelling; under-sink leaks; drainage speed; gas points sealed; exhaust hood functional |
| Bathrooms | ALL tiles tapped for hollow; grout condition; drain speed; toilet flush; water heater; evidence of leaks under and around shower |
| Bedrooms | Window seals (no rain ingress); built-in wardrobe condition; ceiling condition; power points |
| Balcony / yard | Floor gradient (water drains away from building); balcony railing secure; drain clear |
| Roof (landed) | Tile condition; ridge cap; visible rust on purlins; skylight or attic-vent seals |
| Wet areas & A/C | A/C trunking neatly done; water-heater electrical isolation switch present |
| Car porch / garage | Floor cracks; drainage; autogate function; boundary wall condition |
New property VP checklist (specific to developer handover)
When accepting Vacant Possession (VP) for a new property, your legal position is strongest before you sign the VP acceptance form. Once you sign, the 24-month DLP begins — defects can still be claimed but the burden shifts to you to document and report.
- Confirm the VP date is correct — late VP beyond SPA delivery date entitles you to Liquidated Ascertained Damages (LAD) under Schedule G/H of Housing Development Act 1966.
- Walk every room before signing and note all defects on the developer's Defect Form. Keep a copy.
- Photograph or video every defect with timestamp on at the time of VP inspection.
- Check that all specified items are installed: kitchen cabinets, water heaters, A/C points, tiles — cross-reference the SPA specifications list.
- Test all electrical points and plumbing on the day.
- Check the Occupancy Certificate (OC) / Certificate of Completion and Compliance (CCC) has been issued before accepting VP.
- Submit the defect list to the developer's customer service team in writing within the first few weeks and follow up if rectification is not done within 30 days.
Sub-sale vs VP: what to prioritise
| Priority | Sub-sale | New VP |
|---|
| 1 | Water damage & leaks (no recourse after completion) | Completeness of fittings vs SPA specs |
| 2 | Structural cracks & settlement | Waterproofing quality in bathrooms & wet areas |
| 3 | Electrical safety (old wiring) | Tile de-bonding & hollowness |
| 4 | Plumbing leaks & drainage | All services functioning (electrical, plumbing, A/C) |
| 5 | Roof and external waterproofing | Late VP claim (LAD calculation) |
Red flags that should make you walk away (or negotiate hard)
- Active water seeping from ceiling, walls or slab — especially if owner claims “just condensation”
- Multiple large diagonal cracks on structural walls, especially if recent
- Evidence of concealed repairs (freshly painted over cracks or patched tiles)
- Unexplained low selling price for a property in a well-maintained area
- Seller refuses or resists a professional inspection before signing
- No strata approval documents for major renovation works visible in the unit
- Dampness or mould smell in rooms with no visible source
After the inspection: what to do
Sub-sale:
- List all defects with photos and estimated rectification cost.
- Request a price reduction equivalent to rectification cost, or ask the seller to rectify before completion.
- If defects are structural or waterproofing-related, consider engaging a professional building inspector for a formal report (RM500–RM2,000 typically) before proceeding.
- If issues are too severe, exercise your right to walk away before signing the SPA.
New VP:
- Complete the developer's defect form and keep a signed copy.
- Follow up in writing within 30 days if rectification has not started.
- If the developer refuses to rectify within a reasonable period, file a complaint with the Tribunal for Homebuyer Claims (Tribunal Tuntutan Pembeli Rumah, TTPR) under the Housing Development Act 1966.
