Secondary Suites – A Sweet Addition to your Home

There are all sorts of reasons to add a secondary suite to your home. Renting out a secondary suite (if it’s legal in your area) can be a great way to offset mortgage payments. Some build a second suite to host elderly relatives or kids returning from college, and others prefer to have a guest suite for visitors or to use as a bed and breakfast. Whatever your reasons, has a variety of suite options that will suit nearly anyone.


Perhaps the most extreme form of “secondary suite”, building a duplex combines two full houses into one. If you have a large lot, this can be the best way to go, especially if you’re looking to rent out the other half to people you don’t know. Some great duplex plans that HouseplanHunters offers include:
