How can one convert a regular house into an HMO? Does one need any kind of license or permission? If yes, who does one contact (my guess is council's housing department.)? Are there any fire or furnishing regulations?
I'd be really grateful if you share your knowledge or experience concerning the issue.

Yeah, you'll need a planning permission to convert the existing property. You need to have three or more tenants living at the property as at least two separate households, who share the same kitchen, bathroom, etc for the property to be classed as HMO. I believe licence is compulsory if you have 5 or more tenants, but check this out to be cert! I've heard that compulsory fire door requirement has recently been introduced, but again it's best to check to avoid being sued.

Mary Poppins,
thank you so much for the info.
would you, please, recommend, who do I contact to get all the details and the permission? was my guess about the council's housing department correct in any way?

Hope you dont mind that it's not mary poppins replying. If you are applying for planning permission, then you need to apply to your local authority's planning department. If you are applying for HMO licence, then it would be a section within the housing department dealing with the private housing. Good luck!

Hi there. HMOs are often more profitable, but before you start applying for licences, how many people you are planning to rent your house to? Bare in mind that not every lender will lend on houses in multiple occupation, escpecially if you are new to buy to let business.

IvoLets, thank you, I really appreciate your reply, it's been very informative.
cat, why wouldn't lenders give out a loan for HMO's? is it more risky or what? I'm actually thinking of renting a house to 2 families.
