You may have to apply for commercial planning permission if you want to continue renting out your place on AirBnB.
Proposed rules would stop homeowners from renting through the site for more than 60 days a year, and five nights in a row.
The Housing Minister admits the concept of home sharing to make extra income is fine but some owners are using the rental site as a business.
The Housing Department is now looking to see what other cities have done in areas that are both popular with tourists and have a high demand for rented accommodation.
Eoghan Murphy believes that will "make sure that we aren't losing a significant amount of supply of housing out of the normal market for these short-term lettings".
Dublin City Councillor Eilis Ryan believes the Housing Minister should go further than the proposed new rules.
"The scale of Airbnb means that we have to go beyond regulating it, and simply ban it. I don't think it is any contribution to our city at all", she claimed.
