The detailed site plan represents the execution plan which elaborates the construction conditions and plans in detail individual interventions in space. It is adopted in conformity with the Local area development plan of the municipality/city, and Physical urban plans. The Detailed site plan, defines types of interventions in each area, its extent and destination/intended use, and locates in detail the objects in space.

These documents determine the designed spatial organisation and intended use of the space, and its qualification. They are adopted on the national level (Physical Planning and Construction Law), regional (Croatian Counties’ Physical Planning) and local level (Local Area Development Plans – cities and municipalities).

The construction permit is a document required, pursuant to the new Law, for construction of big infrastructure buildings. Its possession shows that the main project has been elaborated in conformity with the location/zoning permit and physical plans. The construction permit must be released in full conformity with the law and regulations, and it is released by the competent Ministry.
The location permit/zoning permit is a document required for the construction of buildings over 400 m² of gross construction surface, and it is released pursuant to the Detailed site plan. It is released by the competent national department, county or municipal branch office,  upon request of the investor. The issued location permit has 2 year validity period from the issue date.
Certificate of occupancy is a document necessary for the approval of use for buildings over 400 m². It is necessary to file for the certificate, and it is issued by the competent national department, county or municipal branch office (the same office which has already issued the main project certificate).

Urban master plan designs in detail the areas suitable for construction (destination of usage), as well as the prescribed construction index (building volume).
Urban master plan is a plan released only for the urban construction-allowed areas, whereas the whole urban administrative area is designed by the Urban physical plan. In conformity with the new Physical Planning and Construction Law, Urban master plan is no longer a liability. However, the urban master plans, which had already been enacted until the adoption of the new Law, remain in force until new physical plan is adopted.

That is the area on which, pursuant to the physical planning, construction has been allowed. The construction areas are divided into urban areas (residential) and individual construction allowed areas (business purposes). The intended use of the land surface/space within the construction area limits is defined by detailed site plan and Physical plan (see above).

Cadastral registration certificate is a document which is, upon request, issued by the municipal cadastral body. The certificate represents the graphic representation of the cadastral plot, marked by precisely defined colours.   The insight into the cadastral plan is enabled to the public, or rather to everyone who submits a regular request. The cadastral registration certificate is a document requested when filing for a location/zoning permit. The information registered with the cadastral office should correspond to the data contained in the land registry. In a cadastral office one can find information with regard to the landed property holding, however not information on property owners.  
 

Land registry certificate is a document which proves the property titles or property ownership. The insight into the Land registry is enabled to the public, or rather to everyone who submits a regular request. The land registry certificate is a document requested when filing for a location/zoning permit and building conditions decree. The information registered with the land registry should correspond to the data contained in the cadastral office files.

Zoning criteria represent the conditions specified by the zoning permit or building conditions decree, and are issued in conformity with physical plans. They determine the height of the building, its position in the space, the lot construction index, etc. The zoning criteria, once determined as such, can not be modified.   

Defines the modalities of intended use of the area, buildings’ intended use and lot design, as well as what types of buildings (residential, business) are pre-designed for a specific area. The intended zone use is marked by specific letters in physical plans, like:

S – only residential buildings
M1 – different use of buildings – mainly residential
M2 - different use of buildings – mainly business
K2 – commercial complexes
T1 – hotels
T2 – tourist villas
LN – nautical tourism ports (marinas)

The main project designs all elements of the building, defined in the preliminary design, in detail (technical solutions, and harmonisation with the relevant laws and regulations). It must be elaborated in conformity with the preliminary design, and it is designed by the authorized architect. In constructing a building up to 400 m², it is not necessary to have the main project confirmed by the competent authority, but such a certificate must always be accessible on the construction site. It is, however, necessary to obtain the certificate in constructing the building bigger than 400 m². The preliminary design is a document needed to obtain the zoning/location permit. It elaborates the position of the building on the lot, and its external features. The preliminary project must be elaborated in conformity with the relevant laws and regulations, and it is designed by the authorized architect
The final design or construction design must be elaborated for all buildings bigger than 400 m². It must follow and define in detail all the technical details in the main project. Different project sections serve as the project manual, instructions to the constructors on the construction site. It is designed by the authorized architect.

Construction conditions decree is a new document which replaces the construction permit, required until recently, and is required only in constructing the building bigger than 400 m². The decree is issued by the competent national office in the county or city (the same office issuing the zoninig permit), once you have applied for it. It has 2 year validity period once it has been issued.

The local area plan is the performance plan which determines the physical development and disposition of the urban unit, or one part of the said unit. The local area plan defines the intended use/destination of the area; as well as its design modalities and usage. At the same time, it defines the interventions to be performed pursuant to the Detailed site plan (UPU). The detailed site plan is regularly adopted for the underconstructed parts of the urban units, and underconstructed separated construction site in the suburbs.

The maritime domain represents the area comprising all islands, coastal belt, land up to 1000 m length from the coastal margin and is delineated in the land chart. All land lots situated on islands, shores or distant from the coastal line 200, 300 or 700 m (less than 1000 m), are situated within the maritime domain. The law prescribes the special construction conditions for such areas, regulating the construction above the margin of 70 to 100 m from the coastal line (depending on the location itself).
