ADU Construction Contractors in Houston, TX for Turning Backyards into Rental Income

We design and build accessory dwelling units that work around your property’s existing footprint. Our ADU construction adds a separate living space in your backyard for rental income, aging parents, adult children, or a private home office. A detached guest house, garage conversion, or tiny home turns unused outdoor space into valuable square footage.

Fire Separation Requirements

ADU Construction Services in Houston, TX

Professional ADU Builders in Houston, TX for Rental Units and Luxury Home Upgrades

We build an ADU in several configurations depending on your property, budget, and needs. Our team handles every part of the ADU project from design through final inspection. Includes foundation, framing, roofing, siding, windows, doors, insulation, drywall, flooring, paint, bathroom, kitchenette, HVAC, electrical, and plumbing.

Detached Guest House

A standalone structure in the backyard. Built with a private entrance, bathroom, kitchenette, and bedroom area. It has everything someone needs to live independently.

Garage Conversion

Turn an attached or detached garage into a living space. Costs less than new construction because the structure already exists.

Tiny Home ADU

A small footprint dwelling unit under 500 square feet. Has bedroom loft, bathroom, kitchenette, and a living area. Works well for rentals because maintenance costs stay low, and rent per square foot is high.

Law Suite

A ground-floor addition attached to the main house, but with a separate entrance. Has a private bathroom and a kitchenette. Law suites work well for aging parents who need to stay close but want their own space.

Above Garage ADU

Space above a detached garage keeps the garage functional while adding living space above. Has stairs leading up and includes a bathroom, a kitchenette, a bedroom, and a living area in the same footprint.

Backyard Office with Bathroom

A hybrid between an ADU and a home office. Contains a private workspace with a bathroom and a small kitchenette. Permitting is simpler because the unit lacks sleeping quarters. Perfect for remote work or a private studio.

Can I Build An ADU On My Property In Houston, TX?
