Country-specific detail
In the Netherlands, a mini-split air conditioner is usually vergunningsvrij (permit-free) under the Omgevingswet when mounted on the rear or side facade of a house. Front-facade placement or placement in a rijksmonument or beschermd stadsgezicht requires an omgevingsvergunning. Noise regulations (Bouwbesluit/Besluit bouwwerken leefomgeving) limit outdoor unit noise to 40 dB(A) at the nearest neighbor's facade, which may restrict placement.
