Federal Act
on Spatial Planning
(Spatial Planning Act, SPA)¹

¹ Provided the es­sen­tial char­ac­ter of the build­ings is pre­served, con­struc­tion work shall be per­mit­ted in un­in­hab­ited build­ings or parts of build­ings where they are used by res­id­ents of an ad­ja­cent res­id­en­tial build­ing for the pur­pose of keep­ing an­im­als as a hobby and an­im­al wel­fare stand­ards are re­spec­ted.

² New out­door in­stall­a­tions may be per­mit­ted in terms of para­graph 1 if they are ne­ces­sary for keep­ing an­im­als in ac­cord­ance with an­im­al wel­fare stand­ards. Such in­stall­a­tions may be lar­ger than the stat­utory min­im­um size provided this is com­pat­ible with the main as­pects of spa­tial plan­ning and the in­stall­a­tion is a re­vers­ible con­struc­tion.

³ The out­door in­stall­a­tions may be used for keep­ing an­im­als as a hobby provided no struc­tur­al al­ter­a­tions are re­quired and there is no new im­pact on the sur­round­ing area and the en­vir­on­ment.

⁴ If an­im­als are kept in a build­ing zone, per­mis­sion shall also be giv­en to fenced-in areas for graz­ing pur­poses provided there is no neg­at­ive im­pact on the land­scape.

⁵ Per­mits in ac­cord­ance with this Art­icle may only be giv­en if the re­quire­ments of Art­icle 24d para­graph 3 are met.

⁶ The Fed­er­al Coun­cil shall reg­u­late the de­tails. In par­tic­u­lar it shall define the re­la­tion­ship between the modi­fic­a­tions pos­sible un­der this Art­icle and those un­der Art­icle 24c and Art­icle 24d para­graph 1.
