ADUs & In-Law Suites in Dallas–Fort Worth

A separate-entry suite for aging parents, an adult child, or guests — independence and proximity at once.

What it is

Family close by, with everyone's privacy intact.

An ADU or in-law suite gives a new resident their own front door, kitchenette, and full bath — while keeping them steps from the main house. It's the multigenerational solution for families whose needs changed faster than their floor plan.

We design for accessibility from the start: zero-step entries, wider doorways, and curbless showers where they're wanted.

FAQ

Common questions.

How much does an ADU or in-law suite cost?

Typically $120,000–$250,000 depending on whether it's detached or attached and the finish level.

Are ADUs allowed where I live?

ADU rules vary by city across DFW. We confirm what's allowed on your lot before design — it's part of why we permit first. See our ADU guide.

Can the suite be made accessible for aging parents?

Yes. We design for accessibility from the start — zero-step entries, wider doorways, blocking for grab bars, and curbless showers on request.

Does it include a kitchen and bathroom?

Yes — a kitchenette and a full, accessible bathroom, so it's a true place to live, not just a bedroom.

Detached or attached — which is right for me?

It depends on your lot, budget, and zoning. We help you weigh a backyard cottage, a garage conversion, or an attached wing.

How long does it take?

Plan on several weeks of design, engineering, and permits, then roughly 16–24 weeks of construction.

Is there a warranty?

Yes — a written workmanship warranty at closeout plus lien releases.
