Currently, the issues of the use and transfer of state land remain quite relevant in Lithuania. According to the data of January 1, 2019, more than 10 percent of the country's territory has not yet been formed and not authorized for use. A large proportion of unauthorized state land is located in major cities in the country. Only a few municipalities in Lithuania have detailed state land use planning. One of them is Panevėžys City Municipality, where, with the help of EU funds, detailed and special plans have been prepared for almost all state land and the municipality is actively looking for ways to encourage residents to become more actively involved in the process of land ownership or use. Detailed territorial planning documents for this municipality were prepared in three stages. Territories near public buildings, apartment buildings, former problem areas were planned. These plans are important for the development and renovation of engineering infrastructure, urban green spaces, management of residential areas, well-being of the population, and so on. Territorial planning documents are an important tool for the sustainable development of territories. The recent adjustment of the detailed plans is based on the principle of continuity. Effective real property management creates good conditions for investors, improvement of infrastructure and living conditions, and replenishment of municipal budget and so on.
