Reconstruction or Adaptation in Montenegro: Permit Rules

The short answer: in Montenegro, work that touches load-bearing elements, changes how the building looks from outside or changes its use is reconstruction, and it needs a building permit. Work that does none of these is adaptation and only needs a notification to the inspector. Like-for-like repairs, such as re-tiling a roof with the same tiles, are maintenance and need nothing at all.

Say you own an old stone house in the Bay of Kotor. It came through the 1979 earthquake and hasn’t had a major repair since, but the walls look solid. The obvious question: can’t we just fix it up?

Here it isn’t that simple. What most of us would call "a renovation", the law splits into two procedures, adaptation and reconstruction, and the difference is real: one needs a notification, the other a full building permit. Below is where the line runs, and why old stone nearly always ends up on the reconstruction side.

What does the law call reconstruction?

The Law on the Construction of Buildings (Zakon o izgradnji objekata, SL CG 19/2025) defines it like this:

"rekonstrukcija podrazumijeva izvođenje radova na postojećem objektu, u postojećem horizontalnom i vertikalnom gabaritu objekta… konstruktivna sanacija odnosno zamjena konstruktivnih elemenata objekta, rehabilitacija oštećenog objekta; ojačanje konstrukcije"

In plain English: work on an existing building, within its existing footprint and height, that changes something substantial - strengthening or replacing load-bearing elements, repairing a damaged structure, or replacing services with a change in capacity.

What matters for an owner is that the law treats reconstruction like new construction. This isn’t repainting the facade. It is building work in the full sense, with design documents and a permit.

How is adaptation different?

Adaptation (adaptacija) is work that doesn’t affect the stability or safety of the building and doesn’t change its load-bearing elements (gradnja.me explains it well). You don’t need a permit for it - you simply notify the urban planning inspector before you start.

Here is the catch many owners only discover on site. If the inspector reads your notification and sees that the work is really reconstruction, an extension or an extra floor, they must warn you within seven days that you need to go through the full procedure.

In other words, you can’t notify an "adaptation" and then quietly rebuild a load-bearing wall or add a floor.

Why does this matter so much for old stone houses?

Because in a traditional stone house the structure is the walls and the timber beams. There is no separate frame inside to carry the load.

So almost anything you do to those walls turns the project from adaptation into reconstruction. That’s not red tape, it’s physics: you can’t change a load-bearing stone wall "just a little" without changing how the whole house behaves.

What about houses from the Yugoslav period?

Stone houses aren’t the only case. A great many buildings in Montenegro went up between the mid-20th century and the break-up of Yugoslavia in the early 1990s. With these, it helps to sort them not into "old" and "new" but into before and after one event.

On 15 April 1979 a devastating earthquake struck the coast, with its epicentre in the Adriatic between Ulcinj and Bar (Boka News looks back). It was a turning point both in lives lost and in building codes.

One detail is often missed: the codes didn’t change on the day of the earthquake. They changed in 1981, in response to it. Reinforced concrete had already become mandatory across Yugoslavia after the 1963 Skopje earthquake, but Montenegro’s detailed seismic design rules were revised and tightened only two years after the 1979 disaster (see Danas and Slobodna Evropa).

What this means for the house you’re looking at:

Built before 1979. Most likely built without modern seismic requirements, or under codes that were replaced in 1981. Its structure probably can’t take the loads a design has to allow for today.
Built after 1981. On paper it followed the updated rules of its time. That doesn’t mean it meets today’s standards - the codes have changed several times since, up to Montenegro’s move to Eurocode 8 - but its structural logic is closer to current practice.
Built between 1979 and 1981. A grey area: formally before the new codes, but already in the shadow of the earthquake. No rule of thumb helps here; you need an engineering survey of that particular building.

So are these houses reconstruction or adaptation?

Legally, the year of construction doesn’t decide anything. Only the nature of the work does: whether it touches the load-bearing structure.

In engineering terms, though, there’s a clear pattern. A house built before the 1981 revision is more likely to need structural work: strengthening columns and beams, adding or replacing reinforcement, work on the foundations. A modern structural check may simply find that the old frame isn’t up to the loads. And any work on load-bearing elements is, by definition, reconstruction.

So Yugoslav-era houses, especially pre-1981 ones, end up as reconstruction more often. Not because the law sorts buildings by age, but because of the state of their structure.

The practical advice is simple: don’t trust "the walls look solid", and don’t judge by the year alone. Get a proper engineering survey of the structure. It will tell you whether you’re looking at adaptation or full reconstruction.

What changed with the 2025 reform?

In March 2025 Montenegro replaced its 2017 law on spatial planning and construction with two separate laws, one on spatial planning and one on the construction of buildings. Both were published in Službeni list Crne Gore No. 19/2025 on 04.03.2025 and came into force on 5 March 2025 (official register; Rona Legal’s overview).

For owners, three things changed in practice:

Permits are local again. The building permit (građevinska dozvola) is now issued by the municipality by default. The Ministry of Spatial Planning, Urbanism and State Property keeps only three groups: state structures of public interest (državni objekti od opšteg interesa), buildings of 3,000 m² gross floor area (bruto građevinska površina) or more, and four- and five-star hotels, tourist settlements and resorts.
A clear sequence. For a reconstruction it goes: UTU (the planning conditions for the plot), concept design, the chief architect’s approval of the concept, main design and independent review, building permit, and finally the notice of start of works. The UTU comes first for a reason - it sets the limits (floors, setbacks, site coverage), and without them you can’t draw a sensible concept (gradnja.me’s building guide walks through it).
Mandatory review. The main design has to be checked by an independent review firm, hired by the investor.

Whose approval do you need for the concept?

For buildings up to 3,000 m² gross floor area - which covers almost every villa and stone house - the concept goes to the municipal chief architect, appointed by the mayor.

Larger projects go to the Chief Architect of Montenegro, appointed by the government on the minister’s proposal. That means buildings of 3,000 m² or more, four- and five-star hotels, tourist settlements and resorts, and also squares, promenades and city parks. In small towns, one municipality’s chief architect may cover a neighbouring one by agreement, so a single architect often serves several municipalities.

One exception matters a lot here: if a reconstruction changes neither the exterior of the building nor its use, the chief architect doesn’t review the concept at all. Approval is needed precisely when the look or the function of the house changes (Articles 22-23 and 32 of the law).

Do I need a permit? Three questions decide

The question we hear most often is: "I’m not knocking down any walls, so why would I need a design?" Fair enough - but the law doesn’t look at how much work you’re doing or what it costs. It asks three questions. Answer them honestly:

Are you touching load-bearing elements? In a stone house: the walls, the floor beams, the foundations.
Does the exterior change? Facade colour, finishing material, the texture of the render, the shape or colour of the roof.
Does the use change? A family home becomes holiday lets, or part of the house becomes business premises.

Now some real-life examples, from simple to tricky:

The roof leaks and you replace the tiles with the same tiles. That’s maintenance (održavanje), which the law actually requires owners to do. No design, no architect, no permit.
The facade has faded and you re-render and repaint it in the same colour and material. Maintenance again. Nothing to file.
You want a new colour, stone cladding on the plinth, or grey tiles instead of red. This is the classic trap. It feels cosmetic because the structure isn’t touched, but a change to the exterior on its own already counts as reconstruction: the law treats any work that changes the building’s appearance compared with the main design as reconstruction. So you need a main design, a permit and the architect’s approval.
You insulate the facade and re-render it. Almost always the exterior changes (texture, sometimes colour, wall thickness), so the full procedure applies. Insulating from the inside, with no change outside and no structural work, is adaptation.
You move lightweight partitions inside and replace wiring and pipes with the same capacities. Adaptation. No permit, but you must notify the inspector.
You make a new opening in a stone wall or replace a rotten beam. That’s a load-bearing element, so it’s reconstruction, with the full procedure.

Two caveats. First, "the same colour" may need proving, so check it against the design and photos of the house before you start. In old stone town centres such as Kotor, facade colour and finish are also protected as heritage, and even a simple refresh is a matter for the conservators (see Kotor and UNESCO: Building Rules in Protected Zones). Second, a design protects you too: without a documented "before" and "after", any dispute with an inspector or a neighbour is lost on paper.

Can I extend the house or add a floor?

Owners often ask: the house is small and the plot allows more, so can we add space while we’re at it? The law draws the line exactly at the building’s outline.

Reconstruction stays within the existing horizontal and vertical outline. Anything beyond it has its own name: an extension to the side is dogradnja, an extra floor on top is nadogradnja.

So a plan to both strengthen and enlarge an old house usually combines two procedures: reconstruction within the outline, plus dogradnja or nadogradnja. If the UTU shows that the permitted site coverage, number of floors and building lines allow it, the extension is legal. But it follows the same route as new construction: a full set of documents and a building permit. A notification won’t do.

Where do the limits come from? DUP, PUP and the new plans

The UTU follows the valid plan for the area that covers your plot. The terminology is confusing, because the 2025 reform renamed the plans. Under the new spatial planning law (Zakon o uređenju prostora, Articles 26, 28 and 29), local plans are:

Prostorno-urbanistički plan lokalne samouprave (municipal spatial and urban plan) - the main plan for the whole municipality, which every municipality must have. It is the closest successor to the old PUP, in name and in role. The main municipal plan had the same name under the 2008 law; the 2017 law moved detailed planning to the state level (plan generalne regulacije), while old PUPs and DUPs stayed valid. The 2025 reform brought the old name back.
Lokalni plan detaljne regulacije (local detailed regulation plan) - the closest successor to the old DUP. It covers individual areas within settlements in detail, with figures for each urban plot: floors, gross floor area, floor area ratio and site coverage, setbacks. The UTU for a plot is part of this plan.
Urbanistički projekat (urban project) - the most detailed document, for complex or valuable areas, and mandatory for historic centres such as Kotor and other places on the register of cultural property. It contains everything a detailed plan does, plus concept designs for the buildings.

Meanwhile the old abbreviations DUP and PUP are still everywhere, because plans adopted earlier stay valid until new ones replace them (they’re listed in the Register of Planning Documents). So one plot may be covered by an old DUP and the next one by a new lokalni plan detaljne regulacije. For an owner, the meaning is the same.

Before you start dreaming of an extra floor or a new wing, find out which plan covers the plot. The ministry keeps the register of valid plans, and you can ask the municipality for an extract. Quite often an old house sits on a plot with more generous limits than what was actually built, and the UTU allows an extension. Sometimes it’s the other way round, and in a strictly protected historic zone you won’t get a single extra metre. How to read these documents is a topic of its own, covered in UTU in Montenegro: What You Can Build on Your Plot.

Questions owners ask

Do I need a permit to repaint my facade?

Not if you use the same colour and the same material: that is maintenance. A different colour or finish changes the exterior, which legally makes it reconstruction, with a design, a permit and the architect’s approval.

Is replacing a rotten beam reconstruction?

Yes. A beam is a load-bearing element, and any work on load-bearing elements is reconstruction.

What paperwork does adaptation need?

No permit, just a notification to the urban planning inspector before work starts. If the inspector sees that the work is really reconstruction, they must warn you within seven days that you need the full procedure.

Who approves the concept design?

For buildings up to 3,000 m² gross floor area, the municipal chief architect. Larger buildings, four- and five-star hotels and resorts go to the Chief Architect of Montenegro. If the exterior and the use don’t change, no approval of the concept is needed.

Can I add a floor during a reconstruction?

Only if the UTU allows it. An extra floor is nadogradnja, which goes beyond reconstruction and needs a full set of documents and a building permit.

In short

The line between adaptation and reconstruction doesn’t depend on whether it feels like "a renovation" or "a build", or only on whether you touch the structure. The law looks at three things: load-bearing elements, the exterior and the use. Change any one of them and it’s reconstruction, with a full permit. Change none and it’s adaptation, with a notification. Like-for-like cosmetic work is simply maintenance. With old stone there’s rarely a choice: the walls are the structure, so serious work on them almost always means reconstruction.

The good news is that since 2025 the rules are clearer. There’s a logical sequence from the UTU to the start of works. Most permits are issued by the municipality again, not by a ministry in Podgorica. And control is tighter: try to slip a structural job through as "adaptation", and the inspector will send you back to the full procedure. Once the permits are in hand, here is how owners run a build from another country.

At ABRIS we do this check from the very first day of a reconstruction project: we set your plans against the UTU, the area plan and the condition of the structure, and then map out a route the law allows.
