Design by-laws

By means of by-laws the municipality can, for specific parts of the area under its jurisdiction, pass regulations relating to the exterior design of structures. The legal basis for the formulation of a design by-law is section 91 of the Hessen Building Code (HBO). The design regulations can take the form of an independent design by-law, or be integrated in a legal zoning plan.
In Frankfurt/Main the design stipulations are for the most part integrated into the legal zoning plans. For the municipality as a whole, however, five independent design by-laws are also legally binding. These design by-laws were compiled for the following areas:

  • Höchst old town
  • Sachsenhausen old town
  • Bahnhofsviertel district
  • "Fressgass" and adjoining streets
  • The buildings on the northern bank of the River Main
  • The cathedral and Römer area

A design by-law regulates the design of buildings (for example the shape of the roof or the materials used), plots of land (for example enclosures, greening) and advertisement space. The design by-law stipulates the design framework that new buildings must adhere to. By way of contrast with a preservation by-law, the design by-law makes precise stipulations with regard to the design of structures that are in the interest of a harmonious urban and architectural overall appearance.
