What city planning authorization is required to settle an exterior air conditioning or heat pump housing?

Verified 14 February 2025 - Directorate for Legal and Administrative Information (Prime Minister)

An Advance Work Declaration (AD) is required to install an air conditioning or heat pump housing if its installation changes the exterior appearance of your building. This is the case, for example, if the case is fixed on your facade or your balcony. We're presenting the regulations.

In any case, your installation must comply with the rules of the MORE: titleContent of your municipality, in particular to avoid causing abnormal neighborhood disorder. To find out about these rules, you must contact the city planning department of your city hall.

Who shall I contact

An RFP may be required depending on whether or not you are changing the exterior appearance of the building:

No change in external appearance

Placing an air conditioning or heat pump unit on the floor and not adjacent to the building does not change its external appearance. It is therefore exempt from formality.

In a protected area, if installing your enclosure requires slab construction, it shall be subject to DP, regardless of its surface.

General case

You must complete and submit your DP by dematerialized means according to the arrangements made by your municipality or on a paper form. Inquire on the website of the city hall or on site.
