ADU House Plans
Accessory dwelling unit (ADU) house plans offer property owners a versatile solution for adding independent living space to their existing lots without the need for purchasing additional land. Whether you’re exploring house plans with attached ADU configurations that connect seamlessly to your main residence or detached cottage-style designs that maximize privacy, these secondary dwellings provide flexible options for multigenerational living, guest accommodations, home offices, or rental income opportunities. Our collection includes everything from compact studio layouts to spacious two-bedroom designs, each thoughtfully crafted to deliver complete living functionality including full kitchens, bathrooms, and comfortable living areas within an efficient footprint.
When selecting ADU house plans, consider how the design integrates with your property’s existing architecture and landscape. Detached units positioned thoughtfully in your backyard create maximum separation and sound privacy, making them ideal for rental situations or adult children seeking independence while remaining close to family. Attached configurations share walls or connect via breezeways, offering convenient access that works beautifully for aging parents who benefit from proximity without sacrificing their own private entrance and living quarters. For properties with pools or entertainment areas, specialized garage plans with ADU functionality or dedicated pool house designs combine guest accommodations with recreational amenities, creating dual-purpose structures that enhance your outdoor lifestyle.
The most successful small ADU house plans prioritize intelligent space planning over sheer size, incorporating features like open-concept living areas that feel spacious and welcoming, strategically placed windows that flood interiors with natural light while maintaining privacy from the main house, and thoughtful storage solutions that keep compact spaces organized and functional. Whether your ADU will serve as a permanent residence for family members, a work-from-home sanctuary separate from household activity, or flexible space that adapts as your needs evolve, choosing a floor plan with the right balance of private and shared spaces ensures long-term satisfaction. Our designs complement popular architectural styles from modern farmhouse to craftsman to contemporary, allowing your ADU to either harmonize with or beautifully contrast your existing home. Many of our ADU plans share similar design considerations with in-law suite plans, featuring accessible layouts and thoughtful separation of living zones that respect everyone’s independence.
