Notification-based house up to 70 m²: the complete guide
A house without a building permit sounded like a rumour a few years back. Since 2023, Polish law has allowed single-family houses up to 70 m² of built-up area to go up on notification alone - a change that compresses months of formalities into a few weeks. Like any shortcut, though, it comes with conditions worth understanding before you get attached to a design.
What "notification-based" actually means
Under the standard route, you need a building permit - a formal administrative decision from the district authority, taking 30 to 90 days on paper (and often longer in practice), and requiring a full construction project plus a stack of paperwork.
Notification-based construction skips the decision: instead, you notify the district office of your intention to build. If the office raises no objection within 21 days, you can start. Simple in principle - but only if every condition below is met.
The conditions, all of which must be true at once
- Built-up area up to 70 m² - note that this is the footprint measured by the outline of the external walls, not usable floor area. A house with a 70 m² footprint typically has 55-65 m² of usable space, depending on wall thickness and layout
- Maximum two storeys - ground floor plus a usable attic or first floor
- Detached - semi-detached or terraced houses don't qualify
- For the investor's own residential needs - not for a client, not for rental
- One such house per plot - only one notification-based house can go on a given cadastral plot
Our answer: TREEVIA NORD 68
We designed the TREEVIA NORD 68 specifically for this route - a built-up area of 67.57 m², comfortably under the 70 m² threshold and compliant with the procedure's requirements.
What's inside:
- A living room with kitchen - an open day zone with generous glazing
- A bedroom - separate and quiet
- A full bathroom - with space for a washing machine
- A technical room - housing the recuperator and heating distribution
- A terrace - a natural extension of the day zone
Where people trip up
- Boundary distances - the notification route doesn't waive the usual minimum distances (4 m from a wall with windows, 3 m without)
- Ground conditions - skipping a site manager doesn't mean skipping the ground survey
- Connections - notification covers the building; utility connections still need their own paperwork
- Change of use - converting the house later into a guesthouse or commercial property will require additional permits
Financing it
The good news: Polish banks do issue mortgages for notification-based houses, following broadly the same process as for a traditionally permitted build - a cost estimate, a schedule and a construction agreement. At Treevia, we prepare documentation to match what banks ask for, which smooths out the credit process.
The takeaway
Notification-based construction is a genuine shift in how Polish house-building works - less paperwork, faster formalities, a lower bar to entry. Pair it with prefabrication and you get a house that moves from decision to keys in a matter of months, not years.
