Dublin city council has received just 315 notifications from people intending to use part or all of their home for short-term lets.
New rules were introduced in July 2019 to tackle a rise in Airbnb and other short-term lets.
During that time just 16 homeowners have applied for planning permission to rent out a property in Dublin city that isn't their principal residence.
Three are awaiting decisions but the rest were either refused, withdrawn or declared invalid.
Owner occupiers are required to register their property if they intend to let out part or all of it but just 315 notifications have been lodged since July last year.
That's despite there being almost 9,500 Airbnb listings in Dublin, according to website Inside Airbnb.
The council has launched 395 investigations with 87 cases resolved since the new rules kicked in. However a target of a thousand investigations a year has been set.
Penalties for non-compliance
Those who don't comply with the statutory planning enforcement requirements face a €5,000 fine and or 6 months in prison if convicted.
Anyone who continues to offer the accommodation after being conviction faces a daily fine of €1,500.
