Why Families Choose This
Built for Family Living
More North Texas families are planning for multigenerational living, aging in place, and flexible guest space. An in-law suite can provide privacy and independence while keeping loved ones close to the main home.
We help homeowners evaluate the best layout for family use, future resale value, and long-term flexibility. Whether the project is attached, detached, or converted from existing space, we coordinate feasibility, design, permits, and construction so the finished suite works for both daily life and local code requirements.
Options
In-Law Suite Types
Estimates only — not guarantees. Actual costs vary by size, site conditions, finish level, and city permit fees. DFW ADU Pro® provides a detailed estimate after a free property-feasibility assessment.
Detached Backyard Guest House
$125,000 – $320,000+
A fully independent structure in your backyard — the most private option for multigenerational living. Separate entrance, full kitchen, and living space. A 500 sq. ft. unit commonly begins around $125,000–$150,000.
Garage Conversion In-Law Suite
$60,000 – $130,000
Convert your existing garage into a fully permitted living unit. The most cost-effective option — you’re converting rather than building from scratch. Includes kitchen, bathroom, and living area.
Attached Addition or JADU
$60,000 – $260,000
Attached additions and interior conversions fit smaller lots and existing homes. Connected internally or with a separate exterior entrance, they can be designed to meet your family’s needs while preserving yard space.
