The Best Duplex House Plans for Rental Income
With spring just around the corner, many homeowners and builders are thinking about new projects and smart investments. Duplex house plans are a practical choice, whether you’re looking to generate rental income, need extra space for family, or want to build a high-demand property.
A duplex provides two separate living spaces under one roof, making the most of a single lot while still maintaining privacy for each unit. For homeowners, this means the chance to offset a mortgage with rental income or create a comfortable setup for multi-generational living. For builders and investors, duplexes offer strong market appeal, making them a solid long-term investment.
Our collection of duplex house plans includes a range of styles, from modern designs to charming classics. No matter your goals, there’s a plan that fits your needs.
