How to Check if a Croatian Property Has Valid Building Permits

Building permit issues are one of the most common and most costly problems foreign buyers encounter when purchasing property in Croatia. Unlike in many Western European countries, where almost every standing structure has full documentation, Croatia has a complex history of informal construction, partial legalization, and regulatory gaps that stretch back decades. A property that looks perfectly normal from the outside may have no valid building permit at all, or may have permits that do not match the actual structure.

Understanding the Croatian building permit system is not optional for foreign buyers. It is a fundamental part of due diligence. This guide explains the types of permits that exist, how to verify them, what the legalization process involves, and what risks a buyer faces if permits are missing or incomplete.

The Two Essential Permits

Croatian construction law requires two distinct permits for any legally constructed building:

1. Gradevinska dozvola (Building Permit)

The gradevinska dozvola is the permit that authorises the construction of a building. It is issued by the local administrative department for construction and spatial planning (upravni odjel za prostorno uredenje i gradnju) at the county or city level, depending on the size and type of the structure. The building permit specifies what can be built: the dimensions, the number of floors, the purpose of the building, its position on the plot, and the technical conditions it must meet.

A building permit is issued based on a complete architectural design (glavni projekt) prepared by a licensed architect or engineer. The permit application must also include proof of legal ownership of the land, a geodetic survey, and confirmation that the proposed construction complies with the local spatial plan (prostorni plan). For larger or more complex buildings, additional studies may be required, such as environmental impact assessments.

The building permit has a validity period. Construction must begin within three years of the permit being issued. If construction does not begin within that period, the permit expires and a new one must be obtained. This is a detail that matters when buying unfinished properties or land with existing permits.

2. Uporabna dozvola (Usage Permit)

The uporabna dozvola is the permit that confirms the building has been completed in accordance with the building permit and is safe and legal to occupy. It is issued after a final technical inspection of the completed building, conducted by a commission that verifies compliance with the approved design, structural safety standards, and all applicable regulations.

The usage permit is the document that definitively confirms a building is legally habitable. Without it, a building technically cannot be legally occupied, connected to utility networks, or registered as a completed structure in the cadastral records. In practice, many buildings in Croatia are occupied without a usage permit, but this creates legal risks for any subsequent buyer.

For buildings constructed before 1968, neither a building permit nor a usage permit was required under the laws in force at that time. These buildings are generally considered legal, though their status should still be verified at the local administrative office.

How to Check Permits at the Local Administrative Office

The primary place to verify building permits is the upravni odjel za prostorno uredenje i gradnju (Administrative Department for Spatial Planning and Construction) at the county or city level where the property is located. Every county and larger city in Croatia has such a department.

To check the permit status of a specific property, the following steps are typically required:

1. Identify the cadastral parcel number (katastarska cestica) of the property. This can be found in the land registry extract or on the DGU (State Geodetic Administration) geoportal at geoportal.dgu.hr.
2. Submit a written request to the local administrative department, asking for information about any building and usage permits issued for the specific cadastral parcel. The request should include the parcel number, the cadastral municipality (katastarska opcina), and the address of the property.
3. Review the response. The department will search their records and provide information about any permits on file. This may take several days to several weeks, depending on the municipality.

In recent years, Croatia has been digitalising permit records through the eDozvola system, which is the electronic permitting platform operated by the Ministry of Physical Planning, Construction and State Assets (Ministarstvo prostornoga uredenja, graditeljstva i drzavne imovine). Building permits issued after the system's implementation can be searched online. However, older permits, particularly those issued before 2000, are often only available in paper form at the local office.

Buyers or their lawyers can also request copies of the original building permit and usage permit documents. These documents contain the approved floor plans, which can then be compared with the actual state of the building to identify any discrepancies.

What Can Go Wrong: Common Permit Issues

Croatia's building permit landscape is shaped by decades of informal construction, wartime disruption, and shifting regulations. The most common issues that affect properties on the market include:

Extensions Built Without Permits

This is arguably the single most common permit issue in Croatia. Property owners add rooms, enclose terraces, build garages, or add entire floors without obtaining the required building permit. These extensions may be solidly built and may have been in place for years or decades, but they have no legal standing. If discovered during a sale, they can delay or derail the transaction.

Enclosed Balconies and Terraces

A particularly frequent issue along the Adriatic coast is the enclosure of balconies and terraces to create additional indoor living space. Many apartment owners have enclosed balconies with glass or aluminium frames, effectively increasing the usable area of the apartment. In almost all cases, this was done without a building permit. The enclosed area does not match the approved floor plan, meaning the actual apartment is legally different from what the permits describe.

Changed Floor Plans

Even when a building has a valid building permit and usage permit, the interior layout may have been changed after the permits were issued. Walls may have been removed or added, rooms may have been repurposed, or the building's use may have been changed (for example, from residential to commercial). Any change that deviates from the approved design technically requires a new permit or at least an amendment to the existing one.

Missing Usage Permits

Many buildings in Croatia have a valid building permit but no usage permit. This typically happens when the owner completed construction but never applied for the final technical inspection. In some cases, the building may not pass the inspection due to deviations from the approved design. A missing usage permit is a significant issue because it means the building has never been officially confirmed as legally habitable.

Buildings Constructed Before Modern Permit Requirements

Buildings constructed before February 15, 1968, are generally treated as legal under Croatian law, even without formal building permits. However, any modifications or extensions made after that date require permits. It is common to find old stone houses on the coast that are legal in their original form but have had rooms, floors, or outbuildings added later without permits.

The Legalization Process

Recognising the scale of illegal construction across the country, the Croatian government enacted the Zakon o postupanju s nezakonito izgrađenim zgradama (Act on Dealing with Illegally Constructed Buildings) to provide a path for legalizing buildings constructed without proper permits. This law has been amended several times, and the deadlines for submitting legalization applications have been extended on multiple occasions.

How Legalization Works

The legalization process involves submitting an application to the local administrative department, along with:

• A geodetic survey of the building as it currently stands
• Photographs of the building from all sides
• An architectural drawing showing the actual dimensions and floor plans
• Proof that the building existed before the relevant cutoff date specified in the law
• Payment of a legalization fee (retribucija), which varies based on the size and location of the building

If the application is approved, the local authority issues a rjesenje o izvedenom stanju (decision on the existing state), which effectively serves as both a building permit and a usage permit for the legalized structure. This document allows the building to be registered in the cadastral records and the land registry as a legal structure.

Limitations of Legalization

Not all buildings can be legalized. Structures built on protected land, in national parks, in flood zones, or in locations that fundamentally violate the spatial plan may be ineligible. The legalization process also does not guarantee that the building meets current construction standards. It simply confirms that the state has accepted the building's existence and granted it legal status.

For buyers, the key question is whether a building that has been legalized carries any residual risk. In general, a completed legalization with a valid rjesenje o izvedenom stanju provides a solid legal foundation. However, buyers should verify that the legalization covers the entire structure, including any extensions or modifications. It is not uncommon for only part of a building to be legalized while later additions remain illegal.

What Happens If You Buy a Property Without Valid Permits

Purchasing a property without valid building permits creates several categories of risk:

• Inability to register the property fully in the land registry. The land registry (zemljisna knjiga) records the ownership of the land and any buildings on it. If a building has no permits, it may not be registered in the land registry at all, or it may be registered with a different description than the actual structure. This can complicate the buyer's legal ownership position.
• Difficulty obtaining a mortgage. Croatian banks require valid building permits and land registry registration as a condition for mortgage lending. A property without permits is essentially unmortgageable, which limits the buyer's financing options and reduces the pool of potential future buyers when the property is resold.
• Risk of demolition orders. In theory, the authorities can issue an order to demolish any structure built without permits. In practice, demolition orders are rare for residential buildings, but they do occur, particularly in areas of high environmental sensitivity or where construction flagrantly violates the spatial plan.
• Inability to obtain utility connections legally. Connecting a building to the electricity, water, and sewage networks requires proof of legal construction. Buildings without permits may have informal or illegal utility connections that can be disconnected.
• Reduced resale value. Properties without permits are harder to sell and typically command lower prices. Informed buyers will either avoid them or demand significant discounts to account for the cost and uncertainty of the legalization process.

Energetski certifikat (Energy Performance Certificate)

In addition to building permits, Croatian law requires an energetski certifikat (energy performance certificate) for any property being sold or rented. This certificate rates the building's energy efficiency on a scale from A+ (most efficient) to G (least efficient) and must be provided to the buyer before the sale is completed.

The energy certificate is prepared by a licensed energy auditor and is valid for 10 years. While it does not directly relate to building permits, it is another document that requires a legal building to produce. A building without permits may not be able to obtain an energy certificate, which creates yet another obstacle to a legal sale.

The requirement applies to all residential and commercial buildings with a usable area exceeding 50 m2. Certain exceptions exist for listed heritage buildings and buildings used for religious purposes.

How to Protect Yourself as a Buyer

Given the prevalence of permit issues in Croatian real estate, foreign buyers should take the following steps before committing to a purchase:

1. Hire a qualified lawyer who specializes in Croatian property law. The lawyer should conduct a full due diligence review that includes checking building permits at the local administrative department.
2. Request copies of the building permit and usage permit from the seller. If the seller cannot produce these documents, treat it as a red flag and verify the status independently.
3. Compare the approved floor plans with the actual property. Walk through the property with the approved architectural drawings and check for discrepancies. Pay particular attention to enclosed balconies, added rooms, converted attics or basements, and any extensions.
4. Check the cadastral records at DGU. The State Geodetic Administration maintains records of all buildings and their footprints. Compare the cadastral map with what actually stands on the plot.
5. Include a permit warranty clause in the purchase contract. The contract should include a representation from the seller that the building has all required permits and that the actual structure matches the permitted design. If this turns out to be false, the buyer should have the right to rescind the contract.
6. If the building has been legalized, request the rjesenje o izvedenom stanju and verify that it covers the entire structure as it currently stands, including all extensions and modifications.

Key Legislation References

The following laws and institutions are relevant to building permits in Croatia:

• Zakon o gradnji (Construction Act) — the primary law governing building permits, construction procedures, and usage permits
• Zakon o prostornom uredenju (Spatial Planning Act) — governs spatial plans and land use regulations
• Zakon o postupanju s nezakonito izgrađenim zgradama (Act on Dealing with Illegally Constructed Buildings) — governs the legalization process
• Ministarstvo prostornoga uredenja, graditeljstva i drzavne imovine (Ministry of Physical Planning, Construction and State Assets) — the central government ministry responsible for construction policy
• eDozvola (edozvola.min-prostora.hr) — the electronic permitting platform for checking recently issued permits

Building permit verification is not glamorous, and it is not the part of property buying that most people find exciting. But in Croatia, it is one of the most important steps in the entire process. A property without valid permits is a property with an uncertain future, regardless of how beautiful its sea view may be. Taking the time to verify permits before signing can save tens of thousands of euros and years of legal complications.
