📰About Labcorp

HeightsMED is a 1,542 sq ft medical office renovation located at 427 W 20th St Suite 425 in Houston, Texas. The project was filed with the Texas Department of Licensing and Regulation (TDLR) under the project name Labcorp. This specific unit is part of a larger development effort by 427 W 20th LLC, which has six other TDLR-registered projects in the area totaling $2,150,000.

Project Scope and Cost

The estimated cost for this renovation is $130,000, which translates to $84 per square foot. This cost is below the Harris County median of $250,000 for similar renovation filings, while the per-square-foot rate is close to the county median of $80. The design firm of record is JZ Interior Design, and the registered accessibility specialist is William T Winning. The work is privately funded on private land for private use.

Construction was scheduled to begin in May 2026, following plan review completion in the same month. The filing indicated a completion date of September 2026. However, TDLR has not yet recorded a final inspection, so the current state of the site is not confirmed in the public record.

Local Context and Records

City of Houston permit records show five building permits issued at this street address between January 2026 and June 2026. A third-party Instagram post mentioned that a HeightsMED MOB at this address was set to wrap up construction in December 2025, though the TDLR record for this specific suite reflects a later timeline.

The area profile for ZIP code 77019, based on U.S. Census ACS 2023 five-year estimates, indicates a population of about 23,662 and a median household income of $108,353. Housing in this ZIP code is mostly renter-occupied. The Harris County unemployment rate was 5.2 percent in July 2026, according to FRED data.
