Country-specific detail
In Poland, installing a mini-split in a detached single-family home typically doesn't require a building permit — it's classified as maintenance equipment installation. However, in multi-unit buildings (blok), changes to the facade (mounting an outdoor unit) usually require approval from the housing cooperative (spółdzielnia) or homeowners' association (wspólnota). Some municipalities may require a zgłoszenie (notification) if the outdoor unit exceeds noise or visual-impact thresholds.
