Renovations, heritage and volumes

When planning renovations in Wittenbach, the Federal Register of Buildings and Dwellings (RegBL) offers essential yet partial insights for homeowners. Among the 1521 registered buildings, 41 are officially protected, while the status of 1473 remains unknown. Given this, it is crucial to contact the municipality early to navigate potential permit requirements. Please note that data for house volume and renovation years are not currently available in the system. Because these specific figures are missing, homeowners should verify building details directly with local authorities before initiating any renovation work to ensure full compliance with municipal regulations.
