Plumber in Cypress, TX: water districts, inspections and hiring

No. Cypress is an unincorporated community in Harris County, and the whole area lies inside the extraterritorial jurisdiction of the City of Houston, according to its Wikipedia entry. There is no City of Cypress water department and no city permit office. Most neighborhoods get water and sewer service from a municipal utility district (MUD) or a similar water district, and the district on your bill is the one that sets the rules for your tap, meter and connection. If you are not sure which district serves your home, enter your address in the TCEQ Water Districts Map Viewer. TCEQ notes that the map shows approximate boundaries only, so confirm with the district or your HOA.

Many districts in west and northwest Harris County buy treated surface water wholesale from a regional authority. The West Harris County Regional Water Authority says it was created in 2001, covers about 232 square miles and more than 150 MUDs, and delivers water to plants that then serve homes. It does not bill homeowners directly; your MUD does.

This is where Cypress differs from the incorporated suburbs. Texas Occupations Code 1301.551 requires every city with more than 5,000 people to regulate plumbing by ordinance and to require a permit for most plumbing work. Because Cypress is not a city, that city permit system does not exist there. Harris County's Office of the County Engineer permit list covers items such as residential construction with septic systems, residential water wells, swimming pools and commercial buildings, but it does not list a general residential plumbing permit for repairs or water heater swaps.

That does not mean there are no rules. Two things still apply:

• The state license requirement. Plumbing for hire must be done or supervised by a TSBPE license holder, inside or outside city limits.
• Your water district's service rules. Public water systems in Texas use the TCEQ customer service inspection certificate (Form 20699) for new construction, for existing service where contaminant hazards are suspected, and after a material improvement, correction or expansion of private plumbing. It checks for cross-connections, backflow protection and lead limits. Only a TCEQ licensed customer service inspector, a licensed plumbing inspector or a licensed plumber with a Water Supply Protection Specialist endorsement may sign it.

Before a large job such as a repipe or a new irrigation or pool connection, call the district operator listed on your water bill and ask whether it requires an inspection or a tap fee. Get the answer in writing.

Cypress stayed mostly rural until the early 1990s and then grew quickly, and the 2020 Census counted 66,150 housing units, according to the same Wikipedia entry. Much of the housing stock is therefore relatively new. In homes built on a concrete slab, supply and drain lines run under the foundation, so finding the leak is the first question when a water bill jumps. Our slab leak guide explains why Houston-area clay soils matter here.

Flooding is the other factor. The area sits in the Cypress Creek and Little Cypress Creek watershed, one of the 23 primary watersheds the Harris County Flood Control District manages, and Hurricane Harvey in 2017 was one of the most significant recent storms to affect the community. Heavy rain can push water into sewer systems and back up through low drains; see our sewer backup guide.

Texas licenses plumbers at the state level, through the Texas State Board of Plumbing Examiners (TSBPE). Under Texas Occupations Code 1301.351, a person other than a responsible master plumber may not do plumbing unless they hold the proper license, registration or endorsement and their work is supervised by a license holder. Anyone who advertises plumbing must secure a responsible master plumber, and license holders must carry the license on them while working. That rule applies the same way in unincorporated Cypress as it does inside Houston.

1. Ask for the name and license number of the person doing or supervising the work, not just the company name.
2. Search it in the Texas plumbing license search, by name or license number.
3. Confirm the status is active and the license type fits the job.
4. Get a written estimate that lists the scope, materials and price before work starts.

Homeowners have one exemption: Section 1301.051 says a property owner does not need a plumbing license to do plumbing in their own homestead. Someone you hire, including a handyman, is not covered by it. Our guide to choosing a plumber covers estimates, payment and warning signs in more detail.
