Application for Checking the Rent Control Regulation

The rent control regulation is a complicated beast and practically screams for IT support. Since the previously toothless provisions were adjusted in favor of tenants at the beginning of this year, here is a web application designed to be as easy to use as possible.

This project involved several challenges:

  • Splitting the required information into questions for a wizard that is as easy to use as possible
  • Simple and intuitive components for the wizard
  • Working out the validation and dependency constraints of the questions to prevent or minimize incorrect answers
  • In the backend, each German address had to be assigned a residential location rating. There was no public database for this
