Multi family House Plans, Floor Plans & Building Designs

Whether you're looking for a duplex, triplex, or a building with even more units, this collection of multifamily house plans has you covered.

If you're a professional builder, townhouses and condos represent an efficient way to build affordable entry-level homes that buyers will love. Or perhaps you're a regular person who wants to share a home with extended family (see house plans with in-law suites here), but still have plenty of privacy. In yet another situation, you could build a duplex or triplex to rent out for additional income while living in one of the units. Whatever your purpose, you'll find your perfect multifamily house plan here.

Many of the homes in this collection feature open floor plans to maximize the square footage. Open kitchens make any space feel bigger and encourage relaxed entertaining. You'll also find master suites with private bathrooms.

Some multifamily house plans feature mirror-reverse layouts, so that each unit is identical but flipped. Others present stacked units with separate entrances. And you might be surprised that some of the house plans in this collection don't look like multifamily house plans at all, but simply appear to be large family homes that have an independent in-law unit attached. These come in handy with not only a live-in relative (like an elderly parent) but a grown child or even a tenant who can bring some extra income. Short-term rentals may be a good choice for smaller units attached to larger homes, too.
