Natural hazards and housing resilience in Bali

What can actually be checked before purchase?

Not a forecast and not a promise that nothing will happen to a home. A real review is a set of records, an inspection, questions for the seller or manager, and a clear list of what a qualified specialist must confirm.

The short answer

Start with the specific parcel and asset, not a district label. Official maps and plans help form questions about place. Building rules provide regulatory context. But only asset records and an independent technical review can answer how this particular home was built and maintained.

1. A district frames a question; an address provides material for an answer

BNPB/InA RISK’s interactive map publishes public hazard and infrastructure layers for Bali. Its useful role is not to label a home risky, but to prevent missed questions about access, water, coastal setting, slope and surroundings.

For a selected asset, retain the address, parcel boundaries, viewing date and the layer reviewed. Without that, the conversation easily becomes a general argument about whether an area is ‘good’.

Badung’s spatial plan applies for 2025–2045. It matters as context for territorial use. It does not prove that a particular building was built correctly, is maintained or will withstand a specific event.

2. Ask for the building file before discussing finishes

Government building regulation provides the broad regulatory framework for building administration in Indonesia. It is not a ready-made checklist for every villa, but it is a reason to ask for records that describe the asset, its work and technical decisions.

The minimum working file depends on the asset and transaction, but the question is always the same: which records exist, who prepared them, which version they are and which part of the home they concern? A plan, specification, work list, alteration records and photographs of concealed work are more useful than a manager’s verbal confidence.

A missing document does not automatically mean a defect. It means the absence stays on the unknowns list and the specialist’s inspection scope should become broader.

3. Water and maintenance are not one question

Do not ask for one answer to ‘does water occur here?’ Break it down: where water reaches the parcel, how it is drained, what was done after heavy rain, who maintains drainage elements and whether these can be seen on site. A map helps identify what to ask; condition is checked through inspection and records.

Ask separately about roof, drainage, tanks, retaining elements, external surfaces and maintenance access. None can be labelled good or bad without inspection, but you can establish whether regular work exists and who is responsible for it.

For an asset in a scheme, add common-area maintenance rules, recent works, access to systems and the route by which an owner reports a problem to the file.

4. Resilience fails at the handover of responsibility

The question does not end on transaction day. Record what is handed over: keys, instructions, equipment list, maintenance contacts, open observations and their remediation dates. If the asset is part of a scheme, separate the private home from common systems and do not assume one person maintains both.

In transaction records, look not for the marketing word ‘warranty’ but for a specific party, scope, period, notification process and evidence. If an answer is oral, it is not yet decision material.

The goal is not a promise of a perfect home. It is to understand which questions are closed by records, which need a specialist and which exposures remain with the owner.

Decision steps

1. Pin down the asset

   Address, boundaries, asset type, stage and viewing date in one working sheet.

2. Turn place into questions

   Review the official layer and record what to ask about access, water and surroundings.

3. Collect records

   Obtain available plans, specifications, work history, maintenance records and responsibility handover.

4. Scope inspection around gaps

   Give a specialist not a general fear but a specific unknowns list and access to the asset.

5. Separate fact from assumption

   Do not enter unknowns into price, timeline or return as confirmed inputs.
