What applies in the canton of Zurich
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 Zurich: buildings and installations up to 2.5 m total height and 6 m² floor area are permit-free in building zones, but not in core zones, protected areas or areas covered by protection orders (§ 1 let. a BVV).
Procedure: garden sheds and outbuildings follow the declaration procedure (§ 14 BVV); smaller projects follow the simplified procedure without profile poles or publication. The municipality decides on the procedure.
Submission: eBaugesucheZH; the switchover date, signatures and any paper enclosures depend on the municipality.
