What to check when buying a finished house in the Carpathians: damp, roof, water, papers

Buying a finished house in the Carpathians looks simpler than buying land. The house is there, you can walk through it, everything seems visible. In practice a viewing without a plan shows exactly what the seller had time to prepare before you arrived. The rest sits under the plaster, under the roof covering, in the borehole and in the state registers. Below is what to look at in a mountain house, in what order, and which documents decide whether the building has a legal owner you can actually name in a contract.

Why a finished house is harder than a plot

A plot is checked against documents and against the ground. A house adds a second object of ownership, its own set of documents, and a physical condition no extract will ever describe. You are checking three things at once: the land, the building as a register entry, and the building as a structure. Skip any one of the three and you either do not become an owner, or you become the owner of a problem.

The land question does not go away. The house stands on a plot, and that plot is a separate object with its own cadastral number. Everything in our guide on how to check a land plot still applies: boundaries, designated use, access, restrictions. Ask for documents on the building and on the land separately, then check that the address and the areas agree with each other.

Three documents before the price is worth discussing

The minimum set is an extract from the State Register of Property Rights, a technical passport, and the document showing the house was accepted into operation. The first shows the owner and any encumbrances, the second describes the building officially, the third proves the building is entitled to exist. You can obtain the first two yourself, before you travel.

1. 1Extract from the State Register of Property RightsOn the Diia portal the service costs 40 UAH (the page notes it may vary with the volume of information), is delivered within an hour, and the result is a PDF. It can be requested about property that is not yours, so you take the extract on the seller's house yourself instead of relying on what they choose to show. It tells you the owner, the basis on which they acquired the property, and any encumbrances such as a mortgage, seizure or prohibition on disposal.
2. 2Technical passportThe procedure for technical inventory was approved by Cabinet of Ministers Resolution No. 488 of 12 May 2023. Under it the technical passport records the main structural elements, summary information on the technical condition, the presence of engineering systems and the year of construction, together with floor plans and a schematic plan. It is the only document where the build year and the make-up of the structure are stated officially rather than verbally. Compare the areas and layout with what you see on site: a discrepancy means alterations nobody entered into the documents.
3. 3Proof of acceptance into operationFor a private house built on the basis of a construction passport, this is the declaration of readiness for operation. The Diia service page states that filing takes around 30 minutes, registration up to 10 working days, and the service is free of charge, and it lists the technical inventory of the object among the required documents. That gives you a simple test: a house lawfully accepted into operation cannot exist without a technical passport.

What you can verify without leaving home

Construction records in the Unified State Electronic System in Construction are publicly open — the State Inspectorate of Architecture and Urban Planning announced the restoration of open access, and the construction activity register lets you search an object by address without logging in. If the seller says the house was built on a construction passport and accepted into operation, the corresponding entries should be visible. No entry is a question you ask before the trip, not after it.

Which permitting route this particular house should have followed is unpacked separately in our guide to the construction passport and the notice of commencement. For private housing in a village it is by far the most common route, and its traces are what you are looking for in the register.

Damp: the one problem that gets covered up

Damp in a mountain house almost always has an address, and there are only a few of them: the side cut into the slope, the roof-to-wall junction, the ground floor above an unventilated crawl space, and external corners hidden behind furniture. A freshly painted patch in one specific spot is not a sign of tidiness; it is a sign that the spot was chosen.

• The smell in closed rooms. Ask to see the house as it is, without airing it before you arrive — in a shut-up house damp is noticeable before it is visible.
• External corners at floor level and walls behind wardrobes: condensation forms there before it forms in the middle of a wall, so that is where the first marks appear.
• The loft: the roof-to-wall junction, the chimney surround, the perimeter of any dormer windows. Staining on the rafters shows even when the ceiling below has been repainted.
• The crawl space. If there is a hatch, go in. Bare damp ground with no membrane and no vents under a living floor is a permanent moisture source for the whole ground floor.
• The uphill side. A wall cut into the slope works as a retaining wall, and water reaches it sideways rather than from above — ask whether there is perimeter drainage and where it discharges.

The slope is where builders economise most often, and the consequences show up inside the finished house. What should have been done there, and what it costs, is set out in our piece on foundations on a slope. Missing drainage is not a minor defect: installing it means excavating back down the foundation, so the landscaping and the apron get rebuilt too.

The honest viewing happens during the heating season. If you are seeing the house in summer, come back in autumn or winter before you sign. It is the cheapest check available: one more trip, against the cost of stripping out a loft conversion or relaying a floor.

Roof, loft and where the water goes

A roof in the mountains carries more than a roof on flat ground: snow, sudden thaws, wind. Inspect it from the loft rather than from the yard — from below you only see the colour of the covering.

Water: where it comes from and whether you can drink it

Most villages in the Kosiv district have no mains water, so the question is not whether there is water but whose it is, how much of it there is in late summer, and what is dissolved in it. Any of the three answers can move the price.

1. The source. Borehole, dug well or a captured spring? Ask about the depth, the year it was made, and whether there is a borehole log recording the aquifer.
2. Yield in a dry month. In May there is water almost everywhere. Ask whether the level dropped in August or in a hard January, and whether neighbours on the same aquifer had the same experience.
3. Whose it is. A well or spring on a neighbour's land, a shared pipe, an informal arrangement — none of that transfers with the house automatically. Ask to be shown where the pipe physically runs and across whose land.
4. The analysis. The laboratory test is commissioned by the buyer, not the seller, and ideally at the end of summer when the level is lowest. Drinking water requirements are set by ДСанПіН 2.2.4-171-10 (Ministry of Health order No. 400 of 12 May 2010), and that is what the laboratory compares your sample against.
5. Wastewater. Where it goes: a septic tank, a cesspit, or a pipe heading somewhere down the slope. Ask who empties it, how often, and whether a tanker can reach the house in winter.

If one of the services is missing altogether, price its installation before you agree terms rather than after. The logic is the same as for an empty plot: utilities for a plot in the Carpathians.

What winter in this particular house will cost

The price of the house is paid once, the heating every year. Most mountain villages have no gas, so look at how the house is actually heated and what happens when somebody lives in it all year rather than for a week in August.

• What heats it now and what the backup is. A single boiler with no alternative is a risk, not a saving.
• Wall material and thickness from the technical passport rather than from conversation. External insulation added later should also be visible in the documents.
• Windows: condensation between the panes, sashes that close tightly, draughts around the frame perimeter.
• Whether the whole house was heated or life happened in two rooms. The unheated part is where the damp will be found.
• The road: who clears snow up to your gate, whether it is a paid service, and who arranges it.

To cost the heating options before the deal rather than after it, see our comparison of heating without gas — wood, pellets and heat pumps.

People, signatures and permissions

The most common reason a deal collapses or slips is not the condition of the house but who else has a claim on it. Establish this early, because some of the answers add weeks rather than days.

• Co-owners and spouses. Property acquired during a marriage needs the other spouse's consent — ask about marital status on the date of acquisition, not today.
• Children. If a child holds ownership of the home or a right to use it, permission from the guardianship authority is required. The service is free of charge but is provided within one month, and that month belongs in the deal timetable from the start, not in a conversation at the notary's office.
• Inheritance. A recently inherited house deserves its own conversation about other heirs and whether all of them have formalised their shares.
• A representative acting under a power of attorney. Check the scope and validity; the mechanics of remote deals are covered in buying from abroad under a power of attorney.

An order of work that saves a trip

1. 1Before you travelOrder the register extract for the house and for the plot, look the object up in the construction activity register, and ask the seller for a scan of the technical passport. Half the houses drop out at this stage, and the journey never happens.
2. 2First viewingLook at the crawl space, the loft and the uphill side, in that order. Photograph the junctions rather than the rooms: you will remember the rooms, you will not remember the roof-to-wall detail.
3. 3Second visitDuring the heating season, with the heating running, ideally with a tradesman who works in the district. Take the water sample on the same trip.
4. 4Before the notaryReconcile the technical passport's areas and layout against the building, confirm who the owners are and whether any minors are involved, and only then discuss a deposit.
