Building permit, setback distances, registration with the grid operator: what matters depends on your federal state and your municipality. BauErlaubt checks the current rules for your carport, garden shed, wallbox or extension and tells you what to do.
Free first assessment. No sign-up.
No bureaucratic jargon, no paperwork. Just the answer for your case.
A few simple questions about your project and your location. That's all it takes.
We match your project against your state building code and the local requirements.
You get a clear first assessment with the points that matter for you and the next steps.
Because the answer online is almost always “it depends”. We tell you what it depends on in your case.
Even without a permit, setback rules, the local development plan and municipal statutes still apply. Miss them and, in the worst case, you pay to tear it down.
A carport that can stand permit-free up to 50 m² in Bavaria needs a permit from 30 m² in North Rhine-Westphalia. BauErlaubt knows the limit for your location.
We keep the requirements up to date as building codes change. Every assessment carries a date, not a forum post from years ago.
Not a vague reply, but a clear assessment with the points that matter for your project and concrete next steps.

Whether your fence or privacy screen is allowed is mostly decided by local rules: the development plan, municipal fencing by-laws, and your federal state's neighbour law. Check these heights and distances before you build.
A wallbox needs no building permit, but it must be registered with the grid operator. Above 11 kW the grid operator must also approve it. Here is what to clarify before installation.
Terrace roofs up to about 30 m² are permit-free in most German federal states. What matters are area, depth, and the distance to your neighbour. These are the sizes and rules that currently apply.
