Architect William Bordeaux designed Isabella Court, built in 1928 and 1929 and opened in 1929 as a mixed-use complex with shops on the ground floor and apartments on the two upper floors. Trudy Hutchings bought it in 1991, and it was listed on the National Register of Historic Places on June 24, 1994.

Isabella Court takes its name from a Spanish Colonial Revival complex whose ground floor has long housed commercial tenants while the upper two floors hold apartments. Many tenants and businesses are oriented toward the arts, and in 2007 the Houston Press gave the building its "Best Artistic Renovation" award. The complex also appears on Houston's Good Brick Tour.
