1st The land on which you intend to build a house must fulfill certain conditions. Land may not be you own but in this case you have to have any other possible right so you can build a house on that plot.

The documents which you should acquire for a building on that plot are needed in the following order:
- Excerpt from the Land Registry (relating to the ownership or the right to build on the plot)
- An agreement or approval of the competent state authorities that you have acquired property rights, building rights or right of easement
- Partnership agreement entered into between the property owner, aiming at a common construction or renovation of buildings
- A concession agreement which is eligible for construction
- Written consent of the owners of the existing buildings in the event that you only restructure, upgrade, reform, or rearrange the building structure.

2nd To request permission to build, your land must be located within the boundaries of the construction area - the Regional Plan for the city or municipal land should be located in the zone in which the permitted construction of buildings for residential use.

In towns and villages it is possible to build a house in the area of the building for residential purposes. A zone in which they can build family houses are mostly marked with letters like S, M and M1.

If your land is located in a sparsely populated part of the construction area (any purpose), it is not possible to obtain a building permit if the area is not developed a detailed master plan (UPU or DPU). It is important to know how many square meters is even possible to build on your land. Regional plans for your area and determine the detailed conditions of construction. It is necessary to see the spatial plan of the city / municipality or a detailed urban plan (UPU or DPU).

3rd Required permits can be obtained only if you have "arranged particles". If your particle part of the construction area and is equipped for the construction in accordance with the regional plan, that means building on a regulated building plot.

Regulated plot of land means that for it ensured all the conditions required for the construction and use of land in accordance with its purpose. This includes:
- Connection to the municipal infrastructure
- Access to the traffic area
- Wastewater disposal plan
- The prescribed number of parking spaces, etc.

4th To get an approval for building conditions, you need a conceptual design. Is says where the building might be placed on the plot structure and how it will look like (how big it would be, how much will have windows and doors, how many rooms ...)

The conceptual design should not be in conflict with the laws and the exisiting regional plans, and this is made by the licensed architect. The price of the conceptual design depends on the preliminary design of the project and service charges authorized by the architect

5th You must pay the "utilities" - water utility and contribution for the construction fee.

The height of the utility contribution is determined for each municipality / city differently (ie for Zagreb averaged 100 kn/m³, while Sibenik 30 m³). Building tax anywhere in Croatia, for a house, is 800 kn.

6th If you are building a house of 400 m² you must have a decision on the construction conditions. It replaces a building permit. The decision issued by the competent national office of the county or city, and to obtain a permit you must submit your request.

The application must be accompanied by:
- Preliminary conceptual design (in triplicate) prepared by licensed architect
- Proof that you have the right to build on the land for which application is submitted (an excerpt from the Land Registry, the agreement on building the right ...)
- Proof that you paid all required contributions and taxes (municipal and water contributions, and building fee)

About your request to the competent body to decide within thirty days. The solution is valid 2 years from issuance.

7. To start building, you must have a major project, which deals with all the detailed elements of construction are defined in the preliminary design (technical solutions engineer and adapt laws and regulations).

The main project should not be in conflict with a conceptual project (design) that is made by a licensed architect. If you are building a house of 400 m2, the project must be drafted and approved by a certified architect, but it should not be confirmed by the relevant bodies (county / city). When you start with the building, the site must have a major project (designed and stamped by an architect). For the preparation of project documentation (conceptual and final design) for a house, it is necessary to allocate an average of about 70,000 kn.

Depending on the type of building or works, the project includes:
- Architectural design,
- Construction project,
- Electrical project
- Engineering project,
- Estimate cost of construction of the building,
- If necessary, and other projects

8th During construction you must ensure the supervision performed by the supervisory engineer (licensed architect or civil engineer) who is authorized to do so by the Croatian Chamber of Architects and Engineers.

The role of the supervising engineer to supervise the construction so that construction be in accordance with the main design and project and in accordance with the law. The role of the supervisory engineer and supervise the contractor and other participants in the building, and report irregularities to the investor (ie you), and building inspection.

A family house up to 400 ^{square meters} you might start using it without a use permit. However, as evidence that the house is built according to the rules, it is the final report of the supervisory engineer. By the end of of construction he is required to prepare a report on supervision. Under the new law that came in the power, only after such a report is drawn up, your house is ready for use.
