Maintenance of a multi-apartment residential buildings is crucial part of the multi-apartment residential building lifecycle. During maintenance phase building manager should act on three main activity types from planning viewpoint. At first, plan and proceed with planned long-term repairs, what are due technical parameters and usable life-time of the materials and technologies used in construction and maintenance during previous periods. Another source to plan and act are tasks and repairs needed on a period of about a year. Third source is to act on problems identified during planned or unplanned inspection due to some incident if not solved during incident event. All identified activities have to be included in maintenance plan of an upcoming period for approval and delegation of finances. Advancements to improve building’s sustainability aspects have to be analysed for a need to plan and apply for construction permit due to the scope of works and complexity. Management company can initiate a suggestion to decision makers for a review and approval of improvements. Approval of maintenance plan also is commitment for funds needed for implementation of planned activities. Improving building’s technical condition leads closer to climate neutral building with reduced carbon footprint. Research is aimed at identifying critical aspects with significant impact on decision-making for sustainability improvements during maintenance phase in multi-apartment residential buildings. Research results identify that important obstacles for renovation in Latvia are hindering incentive approval for improvement. These obstacles are feasible financing options for owners, complex approval of decision for renovation and discrepancies of owner’s perception on short-term and long-term benefits, especially if ownerships are split. Thus, renovation process in Latvia is stagnating. Authors recommend to develop and implement means to increase environmental awareness and to clarify long-term perspective’s economic and environmental benefits.
