Why do you want to make it legal? Shoot, just fix it up real nice and rent it out and when you go to sell it, it's only a problem IF the new buyer doesn't want it. If they don't want it, then just pay the penalty which is going to be prolly $20,000 at the MOST, which is a lot less than $300,000. All the illegal units I have sold on properties the new buyer was happy to get it. They were going to rent it out too and did not care whether it was illegal or not. Before all the goodie too shoes with a lot of money run in here and talk about a tenant getting injured or suing you for renting an illgeal structure, even if they KNOW it's illegal you can settle with them and it'll be a lot less than $300,000. Yes all of this is a risk, but sometimes people take risks. If you got it like that and the numbers work out, Then go for it. If not, pay the possible fine with you have to sell and call it a day. Just my 2 cents.
