Under section 9 of the Salzburg Building Police Act 1997, the authority must consider, among other matters, the zoning plan, development plan, rules on the position of structures and building-law requirements concerning appearance. For a tall and widely visible mast, the ground area is therefore not the only relevant feature.
In an appearance protection area, section 11 of the Salzburg Appearance Protection Act 1999 adds specific rules. The Act also states that this special section does not apply within the City of Salzburg. Whether a particular site is covered must be checked against the applicable regulation and the property.
The location review should therefore include a site plan, height profile, views from relevant directions, antenna arrangement, equipment building and any ancillary facilities. The article on neighbour party status and rights explains the procedural position of affected neighbours.
