Garage Apartments & Garage Conversion ADUs in North Texas
We evaluate your property, verify your city's rules, pull every permit, and build your garage apartment — fully permitted, site-built, and ready for family or rental. DFW ADU Pro® serves 36 cities across the Dallas–Fort Worth Metroplex.
What Is a Garage Apartment?
A garage apartment is a fully independent living unit created by converting an existing garage or building a new structure above or beside a garage. It includes a full kitchen, bathroom, and sleeping area — making it a self-contained dwelling unit that can house a family member, generate rental income, or serve as a home office or studio.
In Texas, garage apartments are classified as accessory dwelling units (ADUs) and require a building permit from your city. Requirements vary by city, zoning district, and HOA. DFW ADU Pro® verifies the applicable rules during the property-feasibility process before finalizing design, pricing, or schedule.
Garage apartments are one of the most cost-effective ways to add a rentable unit to your property — because the structure already exists, you're converting rather than building from scratch. The result is a lower cost per square foot than a detached ADU, with a faster permit pathway in most DFW cities.

Convert your attached garage into a fully permitted living unit. Includes insulation, drywall, flooring, kitchen, bathroom, electrical, and HVAC. The most common and cost-effective garage apartment option in DFW.
Convert a detached garage into an independent living unit. Requires separate utility connections (water, sewer, electrical) in addition to interior finish work. Offers more privacy than an attached conversion.
Build a new living unit above an existing or new garage. Preserves your yard while adding a fully independent unit. Requires structural assessment of the existing garage and may require foundation upgrades.
Build a new detached garage with a living unit above — a carriage house built from the ground up. The highest-cost option but also the most flexible in terms of size, layout, and placement.

Garage Apartment FAQ
What is a garage apartment?
A garage apartment — also called a garage conversion ADU or carriage house — is a living unit created by converting an existing garage or building a new structure above or beside a garage. It includes a full kitchen, bathroom, and sleeping area, making it a fully independent dwelling unit. In Texas, garage apartments are classified as accessory dwelling units (ADUs) and require a building permit from your city.
How much does a garage apartment cost in DFW?
Garage conversion costs in the Dallas–Fort Worth Metroplex typically range from $60,000–$120,000 for a standard garage conversion, or $130,000–$220,000 for a new carriage house built above or beside a garage. Costs vary by garage size, existing condition, utility connections, finish level, and city permit fees. A 500 sq. ft. conversion commonly begins around $60,000–$80,000; larger units, difficult sites, and premium finishes increase costs. DFW ADU Pro® provides a detailed estimate after a free property-feasibility assessment.
Can I convert my attached garage into an apartment in DFW?
Yes, in most DFW cities. Converting an attached garage into a living unit requires a building permit and must meet your city's requirements for ceiling height, egress windows, ventilation, insulation, electrical, and plumbing. Requirements vary by city, zoning district, and HOA. DFW ADU Pro® verifies the applicable rules during the property-feasibility process before finalizing design, pricing, or schedule.
Do I need a permit for a garage apartment in Texas?
Yes. Any garage conversion that creates a habitable living space requires a building permit from your city. Unpermitted conversions create significant liability — they cannot be legally rented, may affect your homeowner's insurance, and must be disclosed in a future sale. DFW ADU Pro® handles all permit applications on your behalf.
Can my HOA restrict a garage apartment?
Yes. HOA covenants are enforceable private agreements in Texas and can restrict or require architectural review for garage conversions regardless of what the city permits. We review your HOA documents during the feasibility assessment and help you navigate the architectural review process where required.
How long does it take to build a garage apartment in DFW?
A standard garage conversion typically takes 3–5 months from permit approval to completion. A new carriage house built above a garage takes longer — typically 5–8 months. Total timeline from initial consultation to move-in depends on permit processing time in your city, design complexity, and site conditions. We'll give you a realistic estimate after reviewing your property.
