Live rule check

Move one socket. Watch the rule kick in.

This is the app's real rule engine. The bathroom below is checked against BFS 2024:8, BBV 26:1 and SS 436 40 00. Move the socket into the shower zone and see what happens.

What we don't promise

  • We don't replace the electrician, plumber or wet-room firm. We show you when you need them.
  • Measurements from photos are estimates. Always measure on site.
  • AI can be wrong. That is why every answer shows its source, and Premium can double-check it.

Questions

Is Byggvett free?

Yes. The free level gives you the renovation guide, floor plans with rule check, calculators, checklists, the rulebook and five AI questions a day. Premium and Platinum add unlimited AI and tools for professionals.

Can I renovate entirely on my own with the app?

You can do a lot yourself, and the app shows exactly what. By law, electrical installation needs a registered electrical contractor, and water and wet rooms need certified firms for your insurance to apply. Byggvett helps you prepare for and check their work.

How do I know the rules are right?

Every requirement shows its source and is marked as law, branch rule, standard or practice. The rules were checked against the source documents in October 2026. Always check the source and the manufacturer's instructions before you build.

Which languages are there?

English and Swedish, plus AI translation into Polish, Romanian, Ukrainian, Lithuanian, Estonian, Latvian, Finnish, German, Spanish, Bosnian/Croatian/Serbian, Turkish and Arabic.

How do Premium and Platinum work?

They are paid per month and you can cancel whenever you want. Premium is for your own renovation. Platinum is for building firms and adds quotes with ROT and your company details on every export.

Your renovation starts with a drawing.
