Act 201/2022 Coll. on construction, approved on 27 April 2022 and promulgated on 7 June 2022, never entered into force: its page in the Collection of Laws shows no time version other than the promulgated text and carries a note that the act was repealed. The preparation of a building today runs on Building Act 25/2025 Coll., in force since 1 April 2025, in the text effective from 1 November 2025.
This text assembles from one act and two decrees a sequence of steps that none of those documents sets out in full, and attaches to each step the deadline that stands in them. It does not assess the quality of the reform, does not state an average length of proceedings, and does not replace advice on any individual building.
What the Building Act replaced and from which day it applies
The 2022 construction act formed a pair with another norm that was to replace the earlier framework, but it never reached practice. Building Act 25/2025 Coll. was approved on 5 February 2025 and promulgated on 19 February 2025 with effect from 1 April 2025 (primary source Slov-lex, Act 201/2022 Coll., promulgated text with the repeal note).
The Building Act itself went through four time versions in its first year. After the promulgated text came versions from 15 March 2025, from 1 April 2025 and from 17 April 2025 under amendment 77/2025 Coll.; the current version applies from 1 November 2025 and derives from amendments 269/2025 Coll. and 144/2025 Coll. When citing a section, the date of the version therefore decides, not the number of the act.
Which documents determine what is filed
The act sets the steps and the decrees set the content. Decree 59/2025 Coll. of the Office for Spatial Planning and Construction on the classification of buildings introduces a four-digit numerical identification code with the levels type, section, group and class, and sorts buildings by their construction-technical execution and their main purpose of use (Decree 59/2025 Coll., in force from 1 April 2025, Slov-lex).
Decree 60/2025 Coll. governs the information system and the content of submissions. Under its § 2 a submission consists of the completed form designated for that submission, the building documentation, the other required attachments and documents, and proof of payment of the administrative fee. An electronic submission does not exceed 100 MB and goes through the information system portal after user authentication (Decree 60/2025 Coll., in force from 1 April 2025, Slov-lex).
Discussing the building intent: who asks whom
The procedure starts before the application. Under § 20(1) the builder, or a designer it authorises, makes the project documentation available in the information system and asks the spatial planning authority and the concerned authorities for binding opinions on the building intent, and the concerned legal persons for binding statements (primary source Slov-lex, Building Act 25/2025 Coll., text in force from 1. 11. 2025).
A concerned authority issues four kinds of act under § 21(3): a binding opinion on the building intent, a compliance clause on the building project, a binding opinion on the approval for use, and a binding opinion on the notification of a building and of building alterations. These are four separate acts in different phases, not four forms of one.
The documentation may be made available under § 20(2) at the stage of the building intent, or at the stage of the building intent and the building project together. The choice of stage determines how many steps run in a single round, and it is the only point in this phase where the builder decides rather than an authority.
The deadlines that run against the authority
The act gives a concerned authority 30 days from delivery of the request to issue a binding opinion, or 60 days for complex structures, of which the authority must inform the applicant. If the authority does not issue an opinion within that period, it is presumed to have no comments or requirements on the content of the building intent, and the designer records that in the report on the discussion of the building intent.
| Step | Provision | Deadline |
|---|---|---|
| Issuing a binding opinion | § 21(9) of the Act | 30 days; 60 days for complex structures |
| Silence of the concerned authority | § 21(9) of the Act | presumption of no comments |
| Builder’s objection to the content of an opinion | § 21(13) of the Act | 15 days from delivery |
| Call to complete an incomplete application | § 50(3) of the Act | 15 days from delivery of the application |
| Notice of commencement of proceedings | § 51(1) of the Act | 7 days from the application being complete |
| Comments where no oral hearing is held | § 51(2) of the Act | at least 7 working days |
| Notice by public notification | § 51(3) of the Act | where there are more than 20 participants |
The period for an opinion is suspended where the request does not contain sufficiently precise underlying requirements: under § 21(8) the authority must call on the applicant to specify them within a set period, during which the period for issuing the opinion does not run. An imprecise brief therefore extends the proceedings not by the days of the call but by the whole time the clarification takes.
From the application to the notice of commencement
The builder files the application with the building authority electronically through the form designated for it. Under § 50(2) it is accompanied by project documentation prepared by an authorised person and by the report on the discussion of the building intent (primary source Slov-lex, Decree 60/2025 Coll., § 2); where the attachments are held in the information system, the application states a direct link to where they are available.
If the application lacks the prescribed particulars, the building authority calls on the builder to complete it within 15 days of its delivery and warns that it will otherwise discontinue the proceedings. The seven-day period for the notice of commencement under § 51(1) runs only from the day the application is complete, not from the day it was filed.
Where there are more than 20 participants, where the proceedings followed an environmental impact assessment, or where a participant’s whereabouts are unknown, the notice is served by public notification. Service to the electronic mailbox of concerned authorities and concerned legal persons is unaffected.
The choice of documentation stage under § 20(2) bears directly on this chain. Making the building intent alone available starts one round of opinions; making the building intent and the building project available together starts the assessment of both stages at once. The first route keeps the documentation cheaper until the authorities take a position; the second shortens the calendar but means the building project is produced before the requirements of the concerned authorities are known.
The same logic returns with objections. Under § 21(13) the builder has fifteen days to challenge the content of a binding opinion before the superior authority, and that period runs from delivery of the opinion, that is at a time when the application to the building authority has not yet been filed. Whoever does not object within that window carries the requirement of the opinion into the building project.
What the chain means for an industrial building
The three longest deadlines in this phase belong to the authorities and together give 30 or 60 days for an opinion, 15 days for any call to complete, and 7 days for the notice of commencement. These are three different proceedings, not one deadline split into parts, and the second of them need not arise at all.
The classification of the building by code is not a formality at the end of the process but an input into it: the type, section, group and class determine which concerned authorities are competent at all, and therefore how many parallel thirty-day periods start at once. For an industrial hall with its own utility connections there are usually more of them than for an office building of the same floor area (primary source Slov-lex, Decree 59/2025 Coll. on the classification of buildings).
It also holds that the periods of the individual concerned authorities run in parallel rather than one after another, because each of them receives its own request under § 20(1). The critical path is therefore the slowest authority and not their number, and a single authority that treats the structure as complex moves the whole round from thirty days to sixty.
The remaining intervals sit with the builder and the act sets no figure for them: preparing the project documentation, classifying the building under Decree 59/2025 Coll., assembling the submission under Decree 60/2025 Coll., and responding to a call. The decision on the building intent has a period of its own that does not appear in the provisions opened while verifying these data, so the sum above is not the total length of the proceedings and is not given here as one (primary source Slov-lex, Building Act 25/2025 Coll., § 50 and § 51).
For an investment project calendar one practical order follows. The building is classified first, because the range of concerned authorities depends on the classification; then the round of opinions starts, its length set by the slowest of them; and only after the report on the discussion of the building intent is the application filed, from which the building authority’s periods run. Steps can overlap within a single round, not across rounds.
