Living overseas - letting a property here

Thirsty I believe Leo is correct. I have a granny flat. Currently unused. I went to get planning to convert the space into a two story extension to create a separate unit and I did not apply for it as such, just as an extension to the family home. I did that precisely because I knew I wouldn't get permission as a separate unit. It's what many people do. Just so you know. If you're selling you just don't sell it as a separated house. (that's why you make sure you have an internal way to get into it (in my case I plastered up the door, neither the house nor the flat know it exists there behind the cooker !). I've often seen houses being sold with granny flats but the majority of them have no planning. As my flat is now there more than 20 years there is nothing the council can do to me about it.

Others, like Leo, would not counsel people to go down this route. You'll find it next on impossible to get permission though. (Leo might confirm).

Rent a room

As long as the structure is part of the house, ie basement flat or converted attached garage it qualifies. A chalet in the garden does not.
 

I would worry about such a lender. As you know on AAM you get varying viewpoints. Many posters are against the idea of investment properties. As you also know, I am not. It's all I know about and I can assure you that as I know knowthing about 'investing/shares' etc and it has been my experience that I made the right decisions for me. I've seen the highs and the low, the bad tenants, the nightmare tenant and the mostly excellent tenants. To me at the end of the day, if the property is giving a good return and is ticking away there in the back ground nearly paying for itself eventually you get to own it and you are then your own person. Your son's money might as well be going somewhere he will have something to show for it as spending it on flippers in NY. BUT you must do the sums. When I stared out interest rates were in double digits for some people. And property can indeed go up as well as down.

I believe we are saying the same thing. You can add an extension/convert a garage or attic and achieve a 'granny flat' set up without planning as long as its under 40 sq m; and that set up qualifies under rent a room.
 

So Revenue don't exclude it from the scheme as older self-contained until would not be subject to the planning issues, and planning compliance isn't in their remit. Since at least 2001 (and probably earlier versions of the acts), it has been illegal to sub-divide a property to create a granny-flat without full planning permission being obtained. Any planning I have seen granted for granny-flat type units includes as a condition that it never be let or occupied by non-family members. In Dublin, you must provide the Council with details of who will occupy the flat and justify their needs. The planning generally states that once the need for a granny-flat no longer exists, the unit must be merged back into the main house.

So in essence, if you have a granny-flat, you can avail of the rent-a-room scheme. The problem arises if you are reported for doing so without planning being in order. If that happens the council will send you an enforcement notice giving you a time frame in which to sort out the situation, detailing the costs that will be levied if you don't do so.
