Parcellation is an essential instrument of city regulation that allows to oblige home-owners to take care of inner-block territories. However, as experience shows, to ensure effective maintenance of the territory, parcellation is not enough. This article considers the factors that influence the quality of maintenance of parcelled inner-block territories. Four blocks in Tolyatti are analysed, including their parameters, the evaluation of the quality of their maintenance, and the interpretation of expert interviews. This analysis helps to illustrate the processes of maintenance in the city, their particular problems and the role of parcellation. Based on the results, further research perspectives are suggested.
