The building plot foreseen for residential building purposes should ensure connection of utility infrastructure of the land or building to water supply system, a sewage system or an electricity and heating system.

The provision of the possibility of using individual sources of electric energy and heat, corresponding to separate provisions regarding energy management and environmental protection, is considered equivalent to the connection to the power and heating network. In case of absence of connection conditions for the water and sewage network, the plot referred to in paragraph 1 may be used for development with buildings intended for people stay, provided that it is possible to use an individual water intake, as well as the use of a septic tank or household wastewater treatment system, if their amount does not exceed 5 m³ per day. If the amount of sewage exceeds 5 m³, collecting or purifying them requires a positive opinion of the competent field inspector for environmental protection.
