What specifically applies in the canton of Lucerne
When replacing a heating system, the outdoor unit is the sticking point: noise protection certificate, distance to the neighbour and design. Several cantons have a notification procedure (Meldeverfahren) for this, but only if the noise certificate is correct. Otherwise an ordinary application is required.
Permit-free in the canton of Lucerne: non-commercial garden and outdoor design features such as open pergolas are permit-free (§ 54 PBV). Tight dimensions apply to small structures; anything larger needs a building application.
Procedure: the "Earthquake Safety Declaration of the Canton of Lucerne" must also be submitted with the building application. Permit-free projects are exhaustively listed in § 54 PBV.
Submission: cantonal eForm plus at least one signed paper copy to the municipality; the city of Lucerne uses cymo ebau.
