The earthquakes that hit the Republic of Croatia in 2020 left behind enormous material damage. On Sunday, March 22, 2020, the citizens of the City of Zagreb and the wider Zagreb area were hit by a strong earthquake of magnitude 5.5 on the Richter scale, and at the very end of the year, on December 28 and 29, earthquakes of magnitude 5.0 and 6.2 struck anyway an impoverished part of Croatia, Banovina. These two, economically differently developed regions, faced the challenges of reconstruction. The main goal of this thesis was to present the stages of renovation that must be completed, starting with preliminary inspections, urgent repair of damage, preparation of the structural condition assessment report after detailed inspections, preparation of renovation design and, finally, realisation of work with expert construction supervision. All renovation procedures are carried out in accordance with the newly adopted Law on Reconstruction, which enables the organized implementation of works. Special attention is focused on the renovation of public purpose buildings, which are under the protection of cultural heritage and which, in addition to the standard requirements of construction regulations, must also meet conservation conditions.
