Most buyers walking into their first landed viewing bring the same mental checklist they used for a condo or HDB flat: how big is the living room, which way does it face, how is the kitchen laid out. Those things matter, but landed property carries a different set of risks that simply do not exist for strata housing. There is no MCST managing the building, no BCA-approved as-built plans that guarantee everything was done properly, and no management office to flag issues before they become yours. After years of walking clients through terrace houses, semi-detached homes and bungalows across Singapore, I have learned that the viewings which save people money are the ones where you look past the renovation and ask harder questions about the land, the structure and the paperwork.
Start with the paper trail, not the paint job
Before you even step inside, pull the basics on the property: the tenure, the land area, and what the URA Master Plan currently zones the plot for. This matters more for landed homes than for condos because your rebuilding potential, and therefore what you can eventually do with the property, is tied directly to the land, not to a fixed unit layout that someone else designed. Two houses that look identical from the road can have very different plot ratios, setback requirements, or conservation status, which affects whether you can extend, add a storey, or rebuild entirely down the road.
Ask your agent or check with URA whether the house sits within a conservation area, a landed housing area with specific guidelines, or near a road reserve that could affect future extensions. If the seller has done any additions or alterations, ask for the approved plans from BCA, not just the seller’s word that everything is fine. This single step catches a surprising number of issues before you get emotionally attached to a house.
Look for unauthorised works, because they are more common than buyers expect
Unapproved extensions are one of the most frequent issues I encounter in landed viewings, and they are often invisible to an untrained eye. A converted store room that was never submitted to BCA, a roofed-over side yard, an extra bathroom squeezed into what used to be a utility area, or a raised platform in the garden that changes the drainage pattern are all things sellers may not disclose because they genuinely do not realise the implications. If these works are not regularised, the liability transfers to you as the new owner once the sale completes.
During the viewing, look for inconsistencies between the layout and what a typical house of that vintage would have. Mismatched flooring where a wall used to be, ceiling height changes between rooms, or roofing material that does not match the rest of the house are all signs worth asking about directly. If anything looks off, request the as-built approval documents before you commit to an Option to Purchase. Regularising unauthorised works after the fact can involve submissions to BCA and sometimes structural remediation, and that is not a cost you want to discover after you have already paid the deposit.
Structural signs that deserve more than a glance
Landed homes, particularly those built several decades ago, come with wear that a fresh coat of paint can hide temporarily but not permanently. Walk the perimeter of the house, not just the interior. Look at the base of external walls for hairline cracks, staining that suggests water seepage, or efflorescence, which is the white powdery residue that indicates moisture has been moving through masonry for some time. Check ceilings in upper floors and any flat roof areas for watermarks, since flat roofs on older bungalows are a common source of long-term leaks.
For older houses, ask whether termite treatment has been done recently and whether there is a maintenance contract in place. Timber structures, roof trusses and even some flooring in pre-1990s houses can be vulnerable, and a termite inspection is inexpensive relative to the cost of remediation. It is also worth checking the age and condition of the electrical wiring and the plumbing, especially in houses that have not been renovated in fifteen or twenty years, since rewiring an entire landed house is a significant undertaking.
If you are seriously considering a particular house, it is worth engaging an independent building inspector or structural engineer to walk through with you before you exercise the Option to Purchase. This is a small cost against the size of a landed transaction, and it gives you leverage to negotiate on price or repairs if issues are found.
Boundaries, party walls and shared access
Semi-detached and terrace houses often share a party wall with the neighbouring unit, and this creates practical questions that condo buyers never have to think about. Ask whether there have been any disputes with the adjoining owner over the shared wall, noise, or maintenance responsibilities. If the house has a shared driveway or a right of way across a neighbour’s land to reach the main road, get clarity on whether this is a formal easement registered against the title, or an informal arrangement that could change if the neighbouring property changes hands.
Boundary lines are another area where assumptions cause problems later. Garden walls, hedges and fences do not always sit exactly on the legal boundary, and encroachments, even small ones, can complicate a future rebuild or renovation. If the plot size and shape matter to your plans, for example if you intend to rebuild eventually, engaging a licensed land surveyor to verify the boundary before you commit is a sensible step, particularly for older houses where boundary markers may have shifted or disappeared over the years.
Practical things worth doing during the viewing itself
Try to view the house more than once, at different times of day and ideally after rain. Water pooling in the driveway or garden after a heavy shower tells you something about drainage that a dry-weather viewing never will. If the estate is known to have experienced flash flooding in the past, it is worth checking PUB’s records for the area and asking neighbours directly, since this is the kind of practical local knowledge that does not always show up in official reports.
Take note of the surrounding houses too. In estates where many neighbours have rebuilt or extensively renovated, you get a sense of what is achievable on similar plots. In estates where the URA guidelines are more restrictive, or where many houses remain in original condition, that can be a signal about zoning constraints or conservation status that limits what future owners have been able to do.
A landed property purchase carries more moving parts than most buyers expect going in, and the viewing stage is where careful attention pays off most, long before any renovation or rebuilding decisions come into play.
