ADU FAQs — Dallas, Texas

Can I build an ADU on my property in Dallas?

Most likely, yes. Dallas allows ADUs in R-10, R-7.5, and R-5 single-family residential zones. Conservation districts and HOAs may have additional requirements. We'll review your specific lot and zoning during the consultation.

How much does an ADU cost to build in Dallas?

ADU costs vary by size, finishes, and site conditions. A basic 400–600 SF detached unit typically starts around $150,000–$200,000+. Larger units with full kitchens, high-end finishes, and complex site work run higher. We provide detailed, transparent estimates before any work begins.

How long does it take to build an ADU?

Permitting typically takes 4–8 weeks. Construction runs 3–5 months depending on size and complexity. Total timeline from design to move-in is usually 5–7 months.

Can I rent out my ADU?

Yes, Dallas permits ADU rentals in most zones. Some neighborhoods have owner-occupancy requirements (you must live in the primary residence). Short-term rental rules vary by neighborhood — we can walk you through what applies to your property.

What's the maximum ADU size allowed in Dallas?

Dallas limits ADUs to the lesser of 1,250 SF or a percentage of your lot size. Maximum height is generally 2 stories or 30 feet. Setback and lot coverage requirements also apply. We design within all code requirements.
