Big Solutions in Small Spaces: Discover DeTray’s ADUs

Affordable, Modern, and Designed for Your Lifestyle

Smaller Spaces, Big Opportunities

Accessory Dwelling Units (ADUs) are an innovative way to maximize your property’s potential. Whether you’re seeking an affordable starter home, a comfortable in-law suite, or a cozy vacation retreat, DeTray’s Custom Housing delivers thoughtfully designed ADUs under 1,250 square feet. Equipped with modern amenities and spacious layouts, these small-scale homes are perfect for your evolving needs.

As cities and counties embrace ADUs to address housing demands, adding one to your property is a forward-thinking investment for your family and future.

Advantages of an ADU

Independent Living

Families can enjoy the best of both worlds – independent spaces that are near enough for support but private enough for comfort.

Family-Focused

Offer seniors a space to enjoy their grandkids while adults keep a caring eye on their parents’ needs.

Income Stream

Turn your ADU into a rental or Airbnb to generate supplemental income, whether for short- or long-term stays.

Affordability

As land becomes scarce and housing prices rise, ADUs remain a budget-friendly way to expand your living space.

Good Investment

An ADU adds value to your property, increasing equity while positioning you for future financial growth.

Modern Amenities in Small Spaces

Our ADUs feature contemporary layouts, energy-efficient designs, and the comforts of a larger home.

Adaptable to Your Needs

Whether for personal use, family, or as an investment, our ADUs can be tailored to suit your specific requirements.

Smart Market Timing

Housing costs may rise, but your investment’s value and fixed mortgage will hold strong against market volatility.

Your Ideal ADU Awaits

Let DeTray’s Custom Housing help you design and build the perfect ADU for your property. Start the journey today!
