Impact Fee Administration

Rudy Moreno, Deputy Assistant Director

About the Impact Fee Administration The Impact Fee Administration, a section of Utility Analysis, is responsible for managing wastewater flows through wastewater capacity reservations (WCR), managing water demands through water commitment letters, and planning the near and long term facilities requirements that will assure reliable service for today and the future.

Who has to submit a Wastewater Capacity Reservation (WCR) Application?

A WCR application must be submitted when a property owner is proposing a new development, redevelopment, an increase in building square footage, or a change in occupancy on their property that is located within the corporate limits of the City or within an area receiving utility services by the City. Reference Chapter 47 in City of Houston Code of Ordinances.

 What is in a Wastewater Capacity Reservation (WCR) Letter?

A WCR Letter contains the following information:

  • Verification of adequate and available utilities that will serve the proposed development
  • Point of connection to the City’s utilities
  • Assessment of applicable impact fees (if due)

How do I submit a WCR application?

1. You may submit a WCR application online via the following link:

You may also submit an application in person at the Houston Permitting Center (1002 Washington Ave., 3rd Floor) by setting an appointment with the Impact Fee Administration via the Online Queuing Service (link below). After setting your appointment, complete the WCR appointment application below and bring with you a recorded deed, survey, County Tax Authority printout, and site plan.

The Number of service units attributable to a new development shall be determined by using the land use equivalency table.

Sample Calculation of Service Units (SU) for 4,000sf Single Family Residence:

                Rate = 1.0000 SU up to 3,000sf (0.0002 SU per sf over 3,000sf)





Impact fees are paid to secure capacity for your development. The fee is based on the number of service units and the utility availability. Credits may be given for conversions or for the removal of existing development.

Utility: Rate:
Wastewater $1,199.11 per service unit
Water $790.83 per service unit

Applications accepted as administratively complete prior to the close of business on Friday, June 28, 2019, will be processed under the previous rate of $1,199.11 per service unit for wastewater and $706.83 per service unit for water. Please Note: The Wastewater and Water Impact Fees are not refundable for any reason including failure to obtain a building permit or failure to complete the project for any reason.

Application fee minimum is $58.37 plus an administration fee for the first acre, and $29.18 for each additional acre.  Please Note: If your proposed development of a structure is over 43,560 square feet the vacant land application fee scale will be used.

Development of low and moderate cost single family housing is exempt from payment of impact fees.  In order to qualify for this exemption, the house must be a single family residence located within city limits having an initial purchase price as certified by the property owner that does not exceed the latest available 12-month listing for median price single family housing in the city as published by the Real Estate Center at Texas A&M University. In the event the initial purchase price exceeds this amount, the property owner making the certification shall pay to the city the full amount of the impact fee as calculated under this section. If publication of the median price for single family housing is discontinued by the Real Estate Center at the Texas A&M University, the mayor is authorized to select another publication that lists the median price of single family houses in the city.
