Tax Increment Reinvestment Zone (TIRZ) is a way for Harris County to reinvest added revenue from new development into the area it originated. The purpose of TIRZ is to attract new investment and encourage new development in an area that would otherwise lag behind in economic growth and/or experience depressed economic activity.

Currently Harris County participates in several TIRZs created and maintained by municipalities.

  • Criteria for Reinvestment (Tax Code 311.005 ):
  • “(a) To be designated as a reinvestment zone, an area must:
  • (1) substantially arrest or impair the sound growth of the municipality or county designating the zone, retard the provision of housing accommodations, or constitute an economic or social liability and be a menace to the public health, safety, morals, or welfare in its present condition and use because of the presence of:
    1. A substantial number of substandard, slum, deteriorated, or deteriorating structures;
    2. The predominance of defective or inadequate sidewalk or street layout;
    3. Faulty lot layout in relation to size, adequacy, accessibility, or usefulness;
    4. Unsanitary or unsafe conditions;
    5. The deterioration of site or other improvements;
    6. Tax or special assessment delinquency exceeding the fair value of the land;
    7. Defective or unusual conditions of title; conditions that endanger life or property by fire or other cause;
    8. Or structures, other than single-family residential structure, less than 10 percentage of the square footage of which has been used for commercial, industrial, or residential purposes during the preceding 12 years, if the municipality has a population of 100,000 or more;”
