Faster, more digital, more customer-oriented
The service offensive is having an impact: With the digital building application via the Hesse building portal, a reorganized service center and optimized internal processes, the building inspectorate has noticeably accelerated its processes. The result: more consultations and faster building permits.
Andreas Kowol, Head of the Building Department, and the Wiesbaden Building Authority report positive results for 2025. Thanks to the digital building permit application via the Hessen Building Portal, a newly organized service center, and optimized internal workflows, the authority has significantly streamlined its processes. The result: more consultations and faster approvals. The numbers speak for themselves.
More advice, better applications
In 2025, the Building Authority provided advice to building owners and architects 1,460 times prior to their applications, a good 20 percent more than in the previous year (2024: 1,199). Andreas Kowol is convinced: "Those who seek advice early on obtain building permits more quickly. Based on this principle, the Building Authority has specifically expanded its advisory services."
High approval rate, short processing times
In 2025, a total of 781 building permit applications and preliminary inquiries were received—an 11 percent increase over 2024. Ninety-four percent of the submitted building permit applications were approved. Only six percent of the applications had to be rejected by the building authority because the requirements were not met.
The processing times are particularly encouraging: Under the simplified procedure, it took an average of 45 days—only half as long as the three months permitted by law. Even special-purpose buildings requiring significantly more review were completed in an average of 75 days.
"It was our stated goal to optimize internal processes and improve service for our customers," said Sandra Matzenauer, Head of the Wiesbaden Building Authority. "These figures show that we are on the right track with our internal measures. We were able to significantly speed up the building permit process—to the benefit of everyone who wants to build in Wiesbaden."
Monument protection: fast and solution-oriented
The Lower Monument Protection Authority, which is part of the Building Authority in Wiesbaden, also reports positive figures: Of the 348 applications received in 2025, 314 were approved—a rate of over 90 percent. On average, it took only about 30 days to reach a decision.
Information almost completely digital
The digitization of information request procedures is virtually complete. Of the 1,704 requests for access to files in 2025, only 40 were handled in person—all others were processed entirely digitally. The same applies to the nearly 2,000 requests for information regarding building encumbrances. In most cases, this saves citizens a trip to the government office and allows them to receive this information even faster.
In 2026 as well, the Building Authority will actively support planners and prospective builders in realizing their projects within the bounds of the law and will actively monitor construction activity in the city.
