Discover thoughtfully designed Accessory Dwelling Unit (ADU) floor plans that maximize every square foot while creating comfortable, private living spaces. Our collection features efficient layouts ranging from 400 to 1,200 square feet, perfect for multi-generational living, rental income, or an independent guest house.

Each ADU plan prioritizes smart spatial flow with open-concept living areas that seamlessly connect kitchen, dining, and living spaces. Carefully placed windows bring in natural light while maintaining privacy, and built-in storage solutions help eliminate clutter. Most plans feature a primary bedroom that can accommodate a queen bed, full bathroom with storage, and dedicated laundry area.

Modern ADU designs incorporate features that today's residents expect, including home office nooks, energy-efficient appliances, and flexible spaces that adapt to changing needs. Many plans offer covered porches or petite outdoor living areas that extend the functional space. Universal design elements like wider doorways and zero-threshold showers ensure accessibility for all ages.

Whether you're looking for a backyard cottage, in-law suite, or rental unit, these ADU plans deliver independent living in a compact footprint. Choose from styles ranging from contemporary to craftsman that complement your main home while maintaining architectural harmony. Each design meets common municipal ADU requirements while incorporating sound isolation and separate mechanical systems for true privacy.

The thoughtful layouts work equally well for aging parents, adult children returning home, or generating rental income in high-demand areas. With rising housing costs, these versatile ADU plans offer an intelligent solution for expanding your property's living space and value while maintaining separate, dignified dwellings for all residents.

More Information

All of our floor plans are designed in-house and come with various options to make your dream home custom to you.

House Plan Modifications

Since we design all of our plans, modifying a plan to fit your need could not be easier. Click on the plan, then under the image, you'll find a button to get a 100% free quote on all plan alteration requests. Our plans are all available with a variety of stock customization options.

Exterior Wall Construction Choices

Most of our stock plans come as 2x4 exterior wall construction by default. We do provide options to change the exterior wall type. Those options include 2x6 exterior walls, Post Frame Construction, CMU Block Construction, etc.

Foundation Types

When de signing our house plans, a default foundation is set for a given plan. If possible, we include options to change the foundation type to better match your construction needs. For instance, if the default foundation is an unfinished basement, you'll have the option to change the foundation type to a walkout foundation, crawlspace, or slab foundation.

Please note: Some of our plans are designed with special foundation needs, such as post and pier for waterfront properties. These plans may not allow an option to choose another foundation type. If you find yourself in need of an alternate foundation and aren't given the choice, please fill out the alteration request on the plan page.

Right Reading Reverse

One of our more popular options is reversing the plan. Ordering the reverse option will not only flip the plan on the sets for you, it will also correct the text to make the plan read correctly while reversed.

CAD Files

All of our plans are offered as digital PDF downloads. If you want to make changes to the plan yourself, there is an add-on option that will give you the CAD files. Our CAD files are exported in AutoCAD format. You must have software capable of opening CAD files to use them. This option is great if you are in the business of home building and need to make slight changes to the plans per lot.

Cost to Build Report

All of our house plans come with a 100% free cost-to-build report. Just find the orange section on the plan page, type in your zip code, and choose your finish quality level. Note that this tool is for estimation purposes only and should not be used in any other way.

Garage Choices

We have multiple options for any desired garage location or type. We offer plans with detached garages, courtyard garages, side-load garages, front load, and rear load garages.

License Types

We offer 2 types of licenses for your house plan. A single-use license means that the plan can be built only once by the person who purchases the plan. An unlimited-build license is meant for pro builders that are planning to build the plan multiple times.

Best Price Guarantee

You may find our plans on other vendors’ websites. Since we design all of our plans we can offer a true price match guarantee. If you find another site selling our plans for cheaper than we are, we will match it.
