Garage Conversion ADUs in Dallas, TX
Transform an underused garage into a fully livable accessory dwelling for aging parents or extended family.
A Cost-Effective Path to Multi-Generational Living
Garage conversions are one of the most practical ways for Dallas homeowners to create a private, safe home for parents or family members without expanding the footprint of the property. Estate ADU converts existing garages into fully functioning ADUs with upgraded foundations, insulation, utilities, and floor plans designed for comfort and accessibility.
We work across Lakewood, East Dallas, the M Streets, Highland Park, University Park, Preston Hollow, and other established neighborhoods where space is limited and family needs are changing. Our team manages feasibility, permitting, design, and construction with a streamlined, white-collar approach that removes guesswork and delivers a finished space that feels intentional, not improvised.
Designed to Match Your Home and Meet Dallas Requirements
Garage conversion ADUs must meet specific zoning, utility, and structural standards in Dallas, and many neighborhoods have additional architectural requirements. Estate ADU handles every detail, from structural reinforcement and slab leveling to ensuring the new living space aligns with the main home’s exterior.
Because garage conversions typically involve fewer permitting hurdles and no major foundation work, they often move faster and cost less than ground-up ADUs. They remain one of the most popular choices for families who want aging parents nearby while maintaining privacy and an efficient budget.

Trusted by Families Across Dallas
Great experience converting a detached garage into a Mother-In-Law Suite. Full kitchen, bathroom, shower and laundry n demand hot water. Punctual and well managed. Jeff and his crews take pride in their work. There was one minor issue with city permitting but it was quickly resolved and was at no fault of EADU. Highly recommend!
