Montenegro Illegal Buildings & Legalization

Last updated: June 2026

Update (June 2026): The cadastre-registration deadline has been extended to 14 August 2026. After geodetic organisations were overwhelmed by appointment demand, the Ministry — at the request of the Union of Municipalities — extended the deadline for registration in the cadastre (upis u katastar), the first prerequisite of the legalization process, by six months from the original 14 February 2026.

If you are buying property in Montenegro in 2026, there is one law you cannot afford to ignore: the Zakon o legalizaciji bespravno izgrađenih objekata — the Law on Legalization of Illegal Constructions, adopted by the Parliament of Montenegro on 31 July 2025 and in force since 14 August 2025 (Official Gazette of Montenegro 91/2025).

This law has materially changed the Montenegrin property market. Estimates suggest between 100,000 and 120,000 illegal buildings exist across the country — roughly 30–40% of all built structures. Under the new law, any property that has not been legalized cannot be sold, mortgaged, or used commercially. The original application window was 14 February 2026, but the cadastre-registration deadline has since been extended to 14 August 2026. By the end of 2025, more than 5,000 applications had reached the Real Estate Administration; the rest of the inventory still risks legal limbo if owners miss the extended deadline.

For foreign buyers, this is the single largest hidden risk on the Montenegrin market right now.

Why this law exists

Illegal construction has been a structural problem in Montenegro for decades. After the 1990s economic collapse and through the rapid coastal expansion of the 2000s and 2010s, large portions of the housing stock were built without proper building permits or with significant deviations from approved plans.

The Ministry of Spatial Planning explicitly cited the failure of earlier legalization frameworks. Under the previous Law on Spatial Planning and Construction (2017), out of 61,647 applications submitted by 2017, only 3,397 buildings were ever legalized — a success rate of just 5.5%.

The 2025 law explicitly states that buildings not yet legalized cannot be sold, pledged, or used for commercial activity. Notaries must verify legalization status before any property transaction.

Five things the law actually changed

1. Satellite imagery as the legal baseline (July and November 2025)

Only buildings visible on the July 2025 imagery can be legalized. The complete orthophoto was officially published on 8 November 2025 by the Real Estate Administration. Structures appearing on this map are eligible; structures not appearing cannot be legalized under any circumstances.

Buildings completed after July 2025 are not legalizable — subject to demolition orders
The cadastre can cancel ex officio any registration of a building not on the imagery — see how the cadastre system works
Žabljak Municipality removed seven buildings constructed after July 2025 in late 2025

2. The application deadline — 14 February 2026, extended to 14 August 2026

Property owners originally had six months to submit legalization applications, to 14 February 2026. That cadastre-registration deadline has since been extended to 14 August 2026. By end of 2025, over 5,000 applications were received — a fraction of the estimated 100,000+ illegal buildings.

3. Transaction restrictions during legalization

Properties without completed legalization cannot be sold, mortgaged, or used commercially. Notaries must verify legal status before any transaction.

4. Pricing and payment structure

Legalization fee estimates:

Coastal residential (Budva, Tivat, Kotor, Bar): €80–€250 per m²
Inland residential (Podgorica, Nikšić): €40–€120 per m²
Commercial or hospitality: €120–€350+ per m²
Plus engineering and surveying costs: €500–€3,000+

A 100 m² illegal house in Budva might cost €10,000–€30,000+ to legalize.

Payment options: one-time with 20% discount, or instalments over up to 30 years.

5. Exclusion zones — buildings that cannot be legalized

National parks (Durmitor, Lovćen, Biogradska Gora, Skadar Lake, Prokletije)
UNESCO World Heritage zones (Old Town of Kotor, Old Town of Perast)
Sanitary water supply protection zones
Coastal protection zones
Areas designated for public infrastructure
Land subject to landslide risk
Within 400 metres of military facilities

What this means for foreign buyers in 2026

Three scenarios exist for any older property:

Scenario A: Building is fully legalized

Clean cadastre record, valid building permits, use permit. Standard transaction — proceed with normal due diligence checklist.

Scenario B: Building is in legalization process (application submitted before the deadline — 14 February 2026, extended to 14 August 2026)

Legalization decision pending (12–36 months). Property may not be transferable until legalization completes. Conditional purchase agreements possible but require sophisticated legal handling.

Scenario C: Building is illegal with no legalization application

No active legalization process (the registration deadline runs to 14 August 2026). Cannot be sold, mortgaged, or used commercially. Do not buy under normal terms.

How to verify legalization status before buying

Layer 1: List nepokretnosti (cadastre extract)

"Uknjižen objekat" — building registered, with permit reference
"Neuknjižen objekat" — building not registered (likely illegal)
"Nije evidentirano" — no building record exists

Our free cadastre check tool does this automatically in three seconds.

Layer 2: Check the November 2025 orthophoto

Compare the property to the official November 2025 orthophoto at www.geoportal.co.me. Any structure visible there is potentially eligible; structures not visible cannot be legalized.

Layer 3: Direct verification with the Real Estate Administration

For unclear cases, request status from the Real Estate Administration or municipality — best handled by a Montenegrin lawyer.

Red flags during property viewing

Visual: Visible additions distinct from main structure, outbuildings lacking permits, buildings unusually close to roads or boundaries.

Documentation: No upotrebna dozvola (use permit), surface area discrepancy between cadastre and physical building, building absent from cadastre records.

Verbal: "We will sort the paperwork after closing," "legalization is in progress" without showing application receipt, "almost everyone has this issue."

Specific high-risk locations

High risk: Ulcinj outskirts, Bar suburbs (Sutomore, Ratac), Budva outer areas (Lazi, Krimovica), Herceg Novi rural areas, Podgorica outer suburbs (Tuzi, Donja Gorica), northern municipalities.

Lower risk: Porto Montenegro, Lustica Bay, Portonovi, Stari Grad Kotor/Budva, Tivat city centre, modern Podgorica buildings (Preko Morače, Blok 5/6, City Kvart). If you are considering land instead, see our buying land guide.

How the Real Estate Administration is enforcing the law

Nov 8, 2025: Complete orthophoto published
Late 2025: Žabljak removed 7 buildings; 4 more in process
End 2025: 5,000+ applications received
Feb 14, 2026: Original application deadline (extended to 14 August 2026)
Ongoing: Cadastre ex officio cancellations; notaries refusing transactions on unlegalized properties

What can still be done with non-legalized property

Wait for a possible future window — uncertain timing, different terms likely
Operate within restrictions — can be owned and occupied, but not sold or mortgaged
Demolition and rebuild — cleanest path to a legal asset
Inheritance — heirs inherit the legal status including inability to sell

How the new framework affects market pricing

Legalized properties trade at 15–25% premium to unlegalized equivalents
Unlegalized properties have become illiquid for foreign buyers
Notary transaction volume declined in late 2025
Premium for legality: expect 15–25% more for clean-legal properties
Discount for legalization-in-process: 5–15% below clean-legal
Unlegalized without applications: heavily discounted or unsalable

Conclusion

The 2025 Law on Legalization is the most significant single piece of Montenegrin property legislation in a decade. The legalization deadline (originally 14 February 2026, extended to 14 August 2026) has reshaped the market: properties are now cleanly bifurcated between legalized (transactable) and unlegalized (restricted).

Three concrete principles:

Verify legalization status before any deposit — list nepokretnosti, building permit, use permit, all three must be checked
Do not buy unlegalized properties unless you accept they cannot be readily resold
Use the November 2025 orthophoto as your reference baseline

The market has become smaller in volume but more reliable. Combined with the 2025 Real Estate Brokerage Law (mandatory agent licensing, written cadastre warnings, professional liability insurance), Montenegro in mid-2026 offers the most clearly-defined foreign buyer protection regime in its history.

Frequently Asked Questions

Can I still buy property in Montenegro safely in 2026?

Yes — but only legalized properties or those with active legalization applications. The 2025 law has not closed the market; it has cleaned it. Buying a properly documented property in 2026 is in fact safer than buying in 2024, because the legal status is now explicit and verifiable.

What if the seller assures me legalization can still be done after closing?

The seller is mistaken or being dishonest. The original application window was 14 February 2026, extended to 14 August 2026; an application must be in before that extended deadline. Do not accept a vague assurance — verify the property has an active legalization application, otherwise it is legally restricted.

Are new-build apartments from developers (Porto Montenegro, Lustica Bay, Portonovi) affected?

No — these developments were built under full building permits and use permits. The 2025 legalization law affects historical informal construction, not modern licensed development. New-build purchases from established developers proceed normally.

What about old buildings in Stari Grad Kotor or Stari Grad Budva?

Old town buildings within historical urban cores typically have building permits from earlier periods (Yugoslav era or before). However, additions, extensions, or interior modifications made informally over the decades may be flagged. A specialist lawyer with historic-urban experience should review these specifically.

How long does legalization actually take for a submitted application?

Realistic estimate: 12–24 months for standard residential buildings under 500 m². 24–36 months for buildings 500–2,000 m² or commercial properties. 36+ months for complex cases, protected areas, or boundary disputes.

Can a non-resident foreigner legalize a property they already own?

Yes — citizenship is not a barrier. The owner of record (regardless of citizenship) can submit and process the legalization. In practice, a Montenegrin lawyer handles the process on the foreign owner's behalf through power of attorney.

Does legalization affect my Montenegrin residence permit application?

Possibly. If your residence permit is based on property ownership and your property is unlegalized, this may affect renewal or new applications. MUP generally accepts properties with active legalization processes; properties without applications submitted by the deadline (extended to 14 August 2026) may face scrutiny.

What happens if the building is partly legal (with permit) and partly illegal (extensions added later)?

The legalized portion remains intact. The illegal additions are subject to the new law: if visible on July 2025 imagery and application submitted by the deadline (extended to 14 August 2026), they can be legalized as separate procedures. If neither condition met, the additions are subject to demolition orders, though the original legal structure remains.

Will the Montenegrin government open another legalization window?

Uncertain. The Ministry has signaled this is intended as a final comprehensive legalization. Political and capacity pressures may eventually force a re-opening, but on what terms is unknowable. Buyers should not plan around a future window.
