For a 3,000 sq ft custom new home in the Dallas area, full architectural services typically run $50,000 – $139,000, about 6%–16% of construction cost. A 2,000 sq ft whole-house renovation typically runs $38,000 – $117,000. An ADU or guest house of about 700 sq ft runs $15,000 – $45,000.
Most residential architects charge a percentage of construction cost, a fixed fee broken into design phases, or hourly rates for smaller or early-stage work. Smaller projects pay a higher share of construction cost because design effort does not shrink in proportion to size.
The median architect salary in the Dallas-Fort Worth-Arlington, TX area is $93,840, 5% below the national median of $99,280 (BLS). Local construction costs matter as much: new single-family homes in this part of the country run a median of about $159 per sq ft (US Census).
Consultants such as structural engineers, surveyors, civil engineers and energy modelers usually bill separately, as do permit and plan-review fees charged by the building department. Ask each architect which consultants their fee includes.
