How we work in Aarau.

Aarau is close enough for us to take on smaller jobs here too. In the canton of Aargau, even small interior alterations rarely go entirely without a procedure — the canton explicitly cites them as an example of the simplified building permit procedure. So we clarify early with the Stadtbauamt (municipal building office) which procedure applies, and we build the waiting time into the programme. In the Old Town, with its painted roof gables, the requirements of the heritage conservation office also apply.

Building permit in Aarau.

The building ordinance of the canton of Aargau (Bauverordnung) lists mainly small outdoor projects (Aussenbereich) as permit-free (§ 49 BauV); for small alterations inside a building, the canton refers to the simplified building permit procedure (§ 61 BauG). The municipality is responsible — in Aarau, the Stadtbauamt (municipal building office), which also answers enquiries before an application is submitted. Properties protected by the canton may only be altered or renovated with the consent of the department (Departement). We clarify your case before work begins.
