Construction site information board

What is a construction site information board?

A construction site information board (informačná tabuľa stavby) is a sign at a site entrance that shows basic data about the building and its participants. The Building Act does not use the word board. It requires the site to be marked as a construction site with basic data about the building and the participants in construction (§ 6 ods. 3 písm. b)). A sign at the entrance is one way to meet that requirement.

The act sets the content in general terms only. The building office can add requirements in the decision on building intent, so read the decision before you print the sign.

Which law requires the marking, and what changed in 2025?

The current basis is the Building Act, Act 25/2025 Z. z. (Stavebný zákon). Its Article I applies from 1 April 2025. This page uses the consolidated version that runs from 1 November 2025 to 31 December 2026. People still search the old titles, so the table separates the three acts.

Act	Status on 13 November 2026	Use for
Act 25/2025 Z. z., Building Act (Stavebný zákon)	Article I in force from 1 April 2025, version of 1 November 2025 applies	Every current rule on this page
Act 201/2022 Z. z., o výstavbe	Repealed by § 86 of Act 25/2025	Nothing current
Act 50/1976 Zb., o územnom plánovaní a stavebnom poriadku	Repealed by Act 200/2022 Z. z. Its last version ran to 31 March 2025	History only

The procedure names changed too. The act reads the old building procedure (stavebné konanie) as project verification (overenie projektu stavby). It reads the old final inspection procedure (kolaudačné konanie) as kolaudácia (§ 84 ods. 11). The step that sets the site requirements is the decision on building intent.

What must the sign show, and who must put it up?

Three provisions of Act 25/2025 work together. The site must be marked as a construction site with basic data about the building and the participants (§ 6 ods. 3 písm. b)). The site manager (stavbyvedúci) must ensure that the site is marked as a construction site with basic data about the building (§ 38 ods. 1 písm. b)). The decision on building intent must set the requirements for marking the site and the building (§ 60 ods. 1 písm. d)).

Section 38 names only the data about the building. Section 6 adds the participants. The act does not say who prints or fixes the sign. It puts the duty to ensure the marking on the site manager, who also manages the site (§ 37 ods. 1).

Requirement	Source in Act 25/2025	Who answers for it
Site marked as a construction site with basic data about the building and the participants	§ 6 ods. 3 písm. b)	The site requirement has no named addressee
Site manager ensures the marking when managing the site	§ 38 ods. 1 písm. b)	Site manager
Specific requirements for marking the site and the building	§ 60 ods. 1 písm. d)	Building office, in the decision on building intent
Relief from some technical site requirements for sites outside built-up areas, linear structures and large sites of other engineering structures	§ 6 ods. 4	Building office, in the decision on building intent

The relief in § 6 ods. 4 refers to technical requirements under § 6 ods. 3. The act does not say which of them the office may waive. Read the decision to see what it waives, and do not assume that the sign is waived.

The building inspector checks the marking. The inspector may find out whether the site is marked, equipped and secured as the act requires (§ 72 ods. 1 písm. d)).

When must the sign go up?

The act sets no number of days for putting the sign up. The site manager must ensure the marking while managing the site (§ 38 ods. 1). Marking the building is preparatory work and does not count as the start of construction (§ 41). Fencing the site, setting up the site facilities and clearing growth are also preparatory work. The sign can therefore go up during the site set-up, before the first construction works.

The site handover is a practical moment to check it.

How does the sign differ from the site diary and the decision?

These are three different things. The sign is the public marking of the site. The decision on building intent is the ruling of the authority, and it sets the marking requirements. The construction diary (stavebný denník) is the record that the site manager keeps (§ 39 ods. 1). The act also requires the verified project and the diary to be on site for the whole construction (§ 6 ods. 5). Having one of these items does not replace the others.

The construction site is a separate concept. It has its own duties for fencing, access and safety (§ 6 ods. 3), and the sign is one item on that list.

What happens if the sign is missing?

No offence in § 79 or § 80 names a missing site marking. Section 79 ods. 1 písm. b) punishes a person who does not secure the site and its facilities. The fine is 30 to 300 EUR (§ 79 ods. 6 písm. a)). The act does not say whether a missing sign falls under that wording. The first person to check is the site manager, because § 38 ods. 1 písm. b) gives that duty to the site manager.

Will the rule change in 2027?

Amendment 243/2026 Z. z. changes Act 25/2025 from 1 January 2027 for its Articles I to XIII. In § 60 ods. 1 it rewrites the opening sentence and letters f and j. It does not list letter d on site marking. Its Article I does not list § 6 ods. 3 or § 38 ods. 1 either. The marking rule therefore stays on the same provisions, but check the consolidated text again after the change date. The amendment also changes § 79 from 1 January 2027.

What should you check before the first works?

• Read the decision on building intent for any requirement on marking the site and the building.
• Compare the basic data on the sign with the decision and the verified project.
• Ask the building office whether the decision waives any site requirement under § 6 ods. 4.
• Place the sign where people can read it from the public access route.
• Update the sign when the contractor or another participant changes.
