Guest Rooms in the Owner's Home: Which CWTON Path Applies

Guest rooms in the owner's home: a separate CWTON path, or the same registration

Renting out two rooms upstairs in your own house, while you live on the ground floor, is a different model from renting a whole, self-contained apartment. The future CWTON system will cover both cases, but how you describe the property, and the day-to-day practice, guest access to shared space, the owner's presence, differ enough that it's worth breaking down before your first guest arrives.

Key takeaways

• Renting rooms in a house where the owner also lives will fall under CWTON registration the same as renting a whole, self-contained unit - but today the register isn't operating and no number can be obtained yet
• When describing the property, you need to precisely state the number of rooms offered and their size, not the total area of the house
• The owner's presence on site doesn't waive good record-keeping or fire safety requirements (smoke detectors mandatory from 30 June 2026)
• Guest access to shared space (kitchen, bathroom) should be clearly stated in the listing, since it directly affects guest expectations and ratings

Will renting a room in your own house require CWTON registration

Yes - once the system launches, without exception. It's worth remembering, though, that the CWTON register isn't operating yet: EU Regulation 2024/1028 has applied since 20 May 2026, but the Polish implementing act has not been passed, and registration is currently impossible. When the system does launch, it will cover every property offering short-term accommodation services, regardless of whether the guest rents a whole, self-contained unit, or a single room in a house also lived in by the owner. The "host-occupied" model won't be a formal exemption from registration in the Polish system, unlike in some other countries where that model is treated more leniently.

How to describe the property

When describing guest rooms in the owner's home (today for the listing and the municipal record, and in future also for CWTON registration), it's key to precisely state what's actually being rented out:

• The number of rooms offered to guests (not the total number of rooms in the house)
• The size of the rooms offered, matching the actual floor area
• Information on access to shared space, if the guest shares a kitchen or bathroom with the owner

An imprecise description (e.g. stating the whole house's floor area instead of just the rooms on offer) can lead to a mismatch between the declared data and the actual situation during an inspection.

Fire safety requirements with the owner present on site

The host being physically present in the building doesn't waive basic fire safety requirements for the section rented to guests, a smoke detector (mandatory from 30 June 2026 in premises where accommodation services are provided), an available fire extinguisher, a clearly marked escape route. In practice, with the host on site, it's easier to ensure a fast response in an emergency, but that doesn't replace formal documentation and equipment requirements.

Keeping records despite close contact with the owner

A common misconception here: in private short-term rental there is no current legal obligation to keep a guest register or logbook (residence books were abolished around 2013). Keeping a simple booking record with guest details is, however, good practice - it makes tax settlement, complaint handling, and any local tax easier, and a separate obligation to report foreign guests to the Border Guard likewise doesn't exist. The common mistake in this model: an owner who personally greets every guest and knows them "by sight" drops any documentation - yet it's worth keeping regardless of how much personal contact there is.

How to describe shared space access in the listing

Clarity in the listing about whether the guest has a private bathroom or shares one with the owner, and whether they have kitchen access, directly affects how well guest expectations match reality, and the number of positive ratings. Hiding this information, or stating it vaguely (e.g. "bathroom nearby" instead of "bathroom shared with the owner"), is one of the more common causes of guest disappointment and lower ratings in this segment of the market.

Frequently Asked Questions (FAQ)

Will I need a separate CWTON number for each room I rent out?

Under the proposed rules, one registration number is to cover the whole accommodation facility, even if several separate rooms within it are rented out simultaneously to different guests. The details will be known once the system launches - today no CWTON number can be obtained at all.

Can I rent out a room only occasionally, a few times a year?

Regularity matters for assessing whether the activity has a commercial character. Occasional, one-off situations tend to be viewed differently from systematically offering a room on booking platforms. For regular activity, it's worth reporting the property to the municipal record today, and completing CWTON registration once that system launches.

Does sharing a bathroom with guests affect fire safety requirements?

The fire safety requirements themselves (smoke detector, fire extinguisher, escape route) don't depend on whether the bathroom is shared, they apply to the whole property where accommodation services are provided.

Will I need to report a change in the number of rooms rented, e.g. if I start renting a third room instead of two?

Once the CWTON system is running, a change in the scope of the property subject to rental (number of rooms, floor area) will usually require updating the records, so the registration reflects the actual state of the offer. Today, when reporting to the municipal record, it's also worth keeping the property's data up to date.
