Poland introduces stricter building codes for balconies, noise insulation, and fencing

New standards for balcony partitions and shared storage

At midnight on 20 September 2026, updated technical building regulations prepared by the Ministry of Development and Technology came into force across Poland. The new rules mandate solid screening partitions between adjoining balconies and loggias in multi-family apartment developments. Builders must install partitions without holes, gaps, or light perforations that could compromise visual privacy between neighboring units. Under the specification, the width of the partition must match the total depth of the balcony minus the width of the balustrade. For any balcony measuring at least 2 metres in depth, the separating wall must have a minimum width of 2 metres. The regulation also requires new apartment buildings to provide dedicated shared storage areas for bicycles and children's strollers, preventing equipment from cluttering residential stairwells, interiors, or balcony spaces.

Acoustic class AQ and fire safety requirements

The technical conditions introduce higher acoustic isolation requirements to curb noise transmission between adjoining residences. Multi-family apartment blocks, semi-detached houses, terraced homes, and two-unit dwellings must now meet specifications set out for acoustic class AQ. In practical terms, this classification requires developers and structural engineers to incorporate thicker walls, sturdier floor slabs, and enhanced partitions separating individual apartments. In addition to sound dampening, the provisions place heavier emphasis on non-flammable insulation materials, specifically mineral wool, to reduce the risk of fire spreading across structural compartments. These rules apply to new construction, extensive remodeling, and formal changes in building usage, whereas existing property owners are exempt from retrofitting unless they initiate substantial modernizations.

Elevators, setback limits, and property boundaries

The updated code also revises structural accessibility and boundary parameters for residential and public properties. Elevators are now mandatory in public utility and collective residential buildings with at least two storeys, as well as in multi-family residential buildings containing at least three storeys. For multi-family developments exceeding four storeys in height, the minimum required distance between a windowless and doorless wall and the plot boundary has been reduced from 5 metres to 4 metres. Property boundaries face tighter restrictions, as gates and entrance wickets must open inward and cannot swing past the property line. Furthermore, sharp security elements such as barbed wire or shattered glass on fences must now stand at a minimum height of 2.2 metres, an increase from the previous 1.8-metre threshold to safeguard pedestrians and animals.

Phased adoption of mandatory solar installations

The regulation outlines a structured schedule for the integration of rooftop photovoltaic systems across different real estate sectors. By the end of 2026, photovoltaic systems become mandatory on selected public utility, collective residential, and commercial or utility buildings with a usable floor area exceeding 250 square metres, provided that installation is technically feasible and economically sound. On 31 December 2029, the mandatory solar installation requirement expands to include new residential buildings and their adjacent covered parking spaces. The regulation has completed all required notification stages, and developers must account for every technical stipulation in project documentation to pass official municipal building acceptance inspections. Buildings listed on the historical monuments register remain exempt from these design constraints within the scope of conservation protection.
