Rent a Room/Rent Supplement

I am aware that income up to 10k euro is tax free under Rent a Room scheme and should be included in Tax Return form 12. If a renter is getting a Rent Allowance does this cause any issues for the owner of thehouse. Would the property be subject to an inspection say by HSE? I assume that as under the rent a room scheme there would be no need to register with the PRTB. Any comments would be much appreciated.

If a person is renting and applying for Rent Supplement, the HSE (Community Welfare Officer) may visit to confirm residency at the start of the claim, or at claim review.
