1Which Building Act (Zakon o gradnji) has governed construction in Croatia since 1 January 2026 and forms the current basis of the state professional examination programme?
A.Zakon o gradnji (Narodne novine 153/13, 20/17, 39/19, 125/19, 145/24)
B.Zakon o prostornom uređenju i gradnji (Narodne novine 76/07, 38/09, 55/11)
C.Zakon o gradnji (Narodne novine 155/25)
D.Zakon o arhitektonskim i inženjerskim poslovima i djelatnostima u prostornom uređenju i gradnji (Narodne novine 152/08)
Explanation: A completely new Zakon o gradnji was published in Narodne novine 155/25 on 23 December 2025 and entered into force on 1 January 2026. Its Article 161 expressly repeals the previous Building Act (NN 153/13, 20/17, 39/19, 125/19, 145/24). Candidates must study the new text, because article numbering, permit validity periods and notification deadlines all changed.
2Under Article 5 of the Zakon o gradnji (NN 155/25), how many essential requirements for construction works (temeljni zahtjevi za građevinu) must every building satisfy over its service life?
A.Six
B.Seven
C.Five
D.Eight
Explanation: Article 5(2) of the Zakon o gradnji (NN 155/25) lists eight essential requirements: mechanical resistance and stability; safety in case of fire; protection against harmful effects on hygiene and health; safety and accessibility; resistance to sound transmission and acoustic properties; energy efficiency and thermal properties; emissions into the external environment; and sustainable use of natural resources. The list was expanded from the previous seven to match the current EU construction products framework.
3Which essential requirement for construction works was newly added to the Croatian list by the Zakon o gradnji (NN 155/25) and did not appear among the seven requirements of the repealed Building Act?
A.Protection against noise and acoustic properties of the building
B.Emissions into the external environment of the building
C.Energy efficiency and thermal properties of the building
D.Safety and accessibility of the building
Explanation: Emisije u vanjsko okruženje građevine (emissions into the external environment) is the seventh item in the Article 5(2) list and is the requirement newly introduced in 2026. Article 12 elaborates it: the building must not, over its life cycle, pose a risk to the external environment through release of dangerous substances, microplastics or radiation into air, groundwater, sea, surface water or soil, through faulty discharge of waste water or flue gases, through damage caused by waterborne pollutants, or through greenhouse gas emissions to the atmosphere.
4Article 13 of the Zakon o gradnji (NN 155/25) sets out the essential requirement of sustainable use of natural resources. Which set of outcomes must the design, construction, maintenance and dismantling of a building secure under that article?
A.Greater resource-efficient use of raw materials and secondary materials, reduced embodied energy and waste, reduced water use, and greater reuse, recyclability and ease of dismantling
B.Use of only domestically manufactured structural materials and a ban on imported insulation products
C.A guaranteed minimum share of the construction budget spent on landscaping and green roofs
D.Mandatory demolition and replacement of the building at fixed intervals to refresh the building stock
Explanation: Article 13 requires that, over the life cycle, use of natural resources be sustainable and secure: greater resource-efficient use of raw and secondary materials of high environmental sustainability; reduction of the total quantity of raw materials used; reduction of total embodied energy; reduction of waste generated; reduction of total use of drinking and sanitary water; greater reuse or recyclability of the building and its materials after dismantling; and ease of dismantling.
5Under Article 18 of the Zakon o gradnji (NN 155/25), what is a core statutory duty of the investor (investitor)?
A.To personally carry out the structural calculations for the load-bearing system
B.To entrust design, project control and nostrification, construction and professional supervision by written contract to persons who meet the statutory conditions for those activities
C.To personally perform the setting-out (iskolčenje) of the building on the plot
D.To sign and seal the architectural drawings forming part of the main project
Explanation: Article 18(1) defines the investor as the natural or legal person in whose name the building is being built. Article 18(2) obliges the investor to entrust design, control and nostrification of projects, construction and professional supervision of construction by written contract to persons who satisfy the conditions for performing those activities prescribed by the Act and by the law governing tasks and activities in physical planning and construction. Article 18(3) additionally obliges the investor to ensure professional supervision of construction.
6Under Article 20 of the Zakon o gradnji (NN 155/25), how does the chief designer (glavni projektant) formally assume responsibility for the completeness and mutual coordination of the individual designs?
A.By lodging a separate declaration of mutual conformity with the building authority before the permit application
B.By obtaining a certificate of coordination from the competent chamber
C.By applying a qualified electronic signature to the title page of the project
D.By having the investor countersign each individual design discipline
Explanation: Article 20(1) provides that where several designers participate, the chief designer is responsible for the completeness and mutual coordination of the designs, and assumes that responsibility by applying a qualified electronic signature to the title page of the project. Article 20(4) extends the same responsibility to amendments of the conceptual, main or detailed design, and Article 20(5) makes failure to comply a serious breach of the duties of an authorised architect or engineer.
7Which restriction does Article 24 of the Zakon o gradnji (NN 155/25) impose in order to protect the independence of the supervising engineer (nadzorni inženjer)?
A.The supervising engineer may not be an employee of the contractor, or of a person connected with the contractor in a way that removes independence, on the same building or works
B.The supervising engineer must be employed by the same firm as the chief designer
C.The supervising engineer may not hold a licence from a professional chamber
D.The supervising engineer must be a civil servant of the competent building authority
Explanation: Article 24(6) provides that the supervising engineer, or chief supervising engineer, may not be an employee of the legal person acting as contractor, nor an employee of a person connected with the contractor in such a way that independence in performing professional supervision on that same building or those works is not ensured. Article 24(5) allows the chief supervising engineer simultaneously to act as supervising engineer for a particular type of works.
8Under Article 28 of the Zakon o gradnji (NN 155/25), when is a project auditor (revident) barred from carrying out the control of a particular project?
A.Whenever the project concerns a building located outside the auditor's home county
B.Whenever the project value exceeds the auditor's professional indemnity cover
C.Whenever the auditor has not personally visited the construction site
D.Whenever the auditor participated wholly or partly in preparing the project, or the project was prepared or nostrified in a legal person employing or owned by the auditor, or the auditor is connected with the designer so that independence is not ensured
Explanation: Article 28(1) prohibits an auditor from controlling a project in whose preparation the auditor participated wholly or partly, or which was prepared or nostrified in a legal person in which the auditor is employed or which is in the auditor's ownership, co-ownership or joint ownership, or where the auditor is connected with the designer in a way that does not ensure independence, impartiality and autonomy in performing project control. Breach is a misdemeanour under the Act's penalty provisions.
9Under Article 79 of the Zakon o gradnji (NN 155/25), a building permit issued by a county or large-city building authority ceases to be valid if the investor does not begin construction within what period from the date the permit became final (pravomoćna)?
A.Three years
B.Six years
C.Two years
D.Ten years
Explanation: Article 79(1) provides that a building permit ceases to be valid if the investor does not commence construction within six years from the date the permit became final. Article 79(2) sets a longer period of eight years for permits issued by the Ministry. Article 79(3) deems construction to have commenced on the date the notice of commencement of construction is lodged.
10Under Article 89 of the Zakon o gradnji (NN 155/25), how and when must the investor lodge the notice of commencement of construction (prijava početka građenja)?
A.In paper form at the municipal registry on the morning that works begin
B.By telephone to the building inspectorate within eight days after works begin
C.Electronically, to the building authority that issued the permit and to the building inspectorate, no later than five days before construction begins
D.Electronically, but only after the first concrete pour has been completed
Explanation: Article 89(1) requires the investor to notify the commencement of construction, or the resumption of works, electronically to the building authority that issued the permit and to the building inspectorate, no later than five days before construction begins. Article 89(2) requires the notice to state the permit reference and date, the contractor and the supervising engineer, and to enclose the certified setting-out report where one is needed.

About the Ovlašteni arhitekt Exam

In Croatia, an architect becomes an ovlašteni arhitekt by passing the state professional examination (stručni ispit za obavljanje poslova graditeljstva i prostornoga uređenja) and then being entered in the register of authorised architects of the Hrvatska komora arhitekata. The examination is conducted by the Ministry of Physical Planning, Construction and State Assets (MPGI) under the Pravilnik o stručnom ispitu (Narodne novine 129/15). Article 11 requires the prescribed education together with at least two years of relevant professional experience, and Article 13 sets out which types of work a candidate of the architecture profession may apply for. The examination is oral, taken before the Ministry's examination commission. Its subject matter changed substantially for 2026: new versions of the Zakon o gradnji and the Zakon o prostornom uređenju (both Narodne novine 155/25) and a new Zakon o energetskoj učinkovitosti u zgradarstvu entered into force on 1 January 2026, the essential requirements for construction works rose from seven to eight, and the Ministry updated its lists of applicable regulations as at 1 January 2026. This page provides independent English-language multiple-choice practice by OpenExamPrep covering that regulatory material.

Exam sponsor: Ministarstvo prostornoga uređenja, graditeljstva i državne imovine (MPGI); registration as ovlašteni arhitekt is handled by Hrvatska komora arhitekata (HKA). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Article 4 of the Pravilnik o stručnom ispitu (NN 129/15) defines five examination subjects. Every candidate sits Osnove tehničke regulative and Regulativa zaštite osoba, okoliša, kulturnih i drugih materijalnih dobara, and then one further subject according to the type of work applied for: Tehnička regulativa prostornog uređenja for professional physical-planning tasks, Tehnička regulativa gradnje for participants in construction, or Tehnička regulativa ispitivanja i potvrđivanja sukladnosti u graditeljstvu. Under Article 13 a candidate of the architecture profession may apply for physical-planning tasks, for participant-in-construction tasks, and for administrative tasks in physical planning and construction.

Time Limit

Ovlašteni arhitekt: Suggested Study Strategy

1Work from the new Zakon o gradnji and Zakon o prostornom uređenju (both Narodne novine 155/25), in force since 1 January 2026. Article numbering changed throughout, so material prepared against the 2013 acts will give you the wrong article for the right rule.
2Learn the eight essential requirements for construction works in Article 5 of the Zakon o gradnji in order, and be able to say what the new seventh requirement, emissions into the external environment (Article 12), adds beyond the hygiene and health requirement in Article 8.
3Commit the changed deadlines to memory: building permit validity of six years, and eight years for Ministry permits (Article 79); notice of commencement at least five days in advance (Article 89); change of investor within 15 days (Article 84); special conditions within 30 days (Article 48); certificate on the main project within 15 days, or 30 days for Ministry permits, with positive silence if it does not arrive (Article 66).
4Use the Tehnički propis o osiguranju pristupačnosti građevina (NN 12/23), which replaced the NN 78/13 ordinance on 28 June 2025. The default accessible ramp gradient is 1:20, with 1:12 permitted only for a height difference of 76 cm or less; a lift is required above 120 cm; corridors are at least 150 cm and the turning circle 150 cm.
5Practise the numerical work the examination expects you to do without notes: kig and kis on a building plot, thermal resistance as d/λ, thermal transmittance as the reciprocal of total resistance including surface resistances, and ramp length from gradient.
6Keep the general administrative procedure separate from the building law in your mind: ZUP Article 4 (party), Article 5 (legality), Article 109 (15-day appeal), Article 123 (reopening) and Article 128 (nullity), then the 30-day deadline for an administrative lawsuit under the Zakon o upravnim sporovima.
7Because the examination is oral, rehearse aloud in Croatian. Take each examination subject in turn and explain the rule, the source and a worked example in a couple of minutes, as you would to the commission.

Frequently Asked Questions

What is an 'ovlašteni arhitekt' in Croatia?

An ovlašteni arhitekt is an architect who has the prescribed education and professional experience, has passed the state professional examination (stručni ispit) conducted by the Ministry of Physical Planning, Construction and State Assets, and is entered in the register of authorised architects of the Hrvatska komora arhitekata. Only a person holding that status may act as the responsible person for design work or for professional supervision of construction within the tasks of the architecture profession, under Articles 17 and 18 of the Zakon o poslovima i djelatnostima prostornog uređenja i gradnje.

Who conducts the architect professional examination in Croatia?

The examination is conducted by the Ministry of Physical Planning, Construction and State Assets (MPGI), not by the Chamber. Under Article 16 of the Pravilnik o stručnom ispitu (NN 129/15) the examination is taken before the Ministry's examination commission, whose president and members the minister appoints for each professional field. The application is lodged on form SIG-1 electronically or at the Ministry in Zagreb, and the Ministry issues the certificate of the passed professional examination and keeps the register of issued certificates. Registration as an authorised architect is then handled by the Hrvatska komora arhitekata.

What are the eligibility requirements for sitting the examination?

Article 11 of the Pravilnik (NN 129/15) sets the conditions. The principal route requires completion of a graduate university study, an integrated undergraduate and graduate university study or a corresponding specialist graduate professional study with at least 300 ECTS, together with at least two years of work experience on relevant tasks in the profession or on other relevant tasks. Article 11 also provides alternative routes for holders of undergraduate degrees and, for some types of work, for technicians at HKO level 4.2, each with its own experience requirement. Article 13 then determines which types of work a candidate of the architecture profession may apply for. Note that the additional conditions for entry in the Chamber's register of authorised architects are set separately by the Chamber legislation and Statute.

What is the format of the official examination?

Article 29 of the Pravilnik (NN 129/15) states that the professional examination is taken orally, with minutes kept on form SIG-2. There is no written paper and no defence of a submitted professional work. Article 4 defines five examination subjects; every candidate sits Osnove tehničke regulative and Regulativa zaštite osoba, okoliša, kulturnih i drugih materijalnih dobara, plus one further subject determined by the type of work applied for. Under Article 30 the overall result is recorded as passed or not passed, and each subject is separately marked satisfied or not satisfied.

What happens if a candidate fails a subject?

Under Article 33 of the Pravilnik (NN 129/15), a candidate who sat the examination and failed at most one examination subject may sit a supplementary examination (popravni ispit) in that subject, held not less than 30 and not more than 60 days after the examination at which the subject was failed. Under Article 37 the supplementary examination costs 30% of the full examination fee, which is €39.82. A candidate who did not pass the examination may sit it again no earlier than 30 days after the previous sitting, under Article 34.

What changed for the 2026 examination?

A great deal. New versions of the Zakon o gradnji and the Zakon o prostornom uređenju, and a new Zakon o energetskoj učinkovitosti u zgradarstvu, were all published in Narodne novine 155/25 and entered into force on 1 January 2026, repealing the 2013 framework. The essential requirements for construction works rose from seven to eight with the addition of emissions into the external environment; building permit validity rose from three to six years, and eight years for permits issued by the Ministry; the notice of commencement of construction is now lodged electronically at least five days in advance; the detailed development plan (DPU) is no longer a plan type; and energy certification moved to the new energy efficiency act. Separately, the Tehnički propis o osiguranju pristupačnosti građevina (NN 12/23) replaced the 2013 accessibility ordinance on 28 June 2025. The Ministry updated its lists of applicable regulations for the examination programme as at 1 January 2026, and study materials written before these changes cite repealed provisions and article numbers.

How does this practice bank relate to the official examination?

The official assessment in Croatia is an oral examination conducted in Croatian before a state examination commission. This bank is an independent English-language multiple-choice study adaptation by OpenExamPrep of the statutory and technical material that examination covers. It is not an official translation, not a simulation of the oral format, and not a substitute for practising oral answers in Croatian. It keeps the Croatian legal and technical terminology and official act names in place, and explains them in English, so that candidates can test their command of the underlying rules. Always verify current provisions against the Ministry's published Izvori za polaganje and the Narodne novine text before the examination.
