Which offices issue these permits in Harris County?

Permits for a contractor or trade in Harris County, TX come from 3 separate offices: Harris County Engineering Department, Office of the County Engineer, Permits Division, Texas Secretary of State, Texas Department of Licensing and Regulation. No single office issues them all, which is why an opening means filing in several places rather than one.

What does a contractor or trade need in Harris County that other businesses do not?

2 of the 2 permits particular to a contractor or trade here apply to no other business type we cover in Harris County: Contractor Licensing — State Trade Licenses Apply (Harris County) and Electrical Contractor License.

Contractor Licensing — State Trade Licenses Apply (Harris County)

No fee applies. Harris County Engineering's own Permits A to Z page — covering commercial building and site development, floodplain, on-site sewage, fire-protection systems and the Certificate of Compliance — lists no general contractor license or registration; Texas counties have only the regulatory powers the Legislature expressly grants them. A contractor doing work in unincorporated Harris County still needs the underlying trade credentials that are state functions where they apply, such as a Texas Department of Licensing and Regulation electrical contractor license or a Texas State Board of Plumbing Examiners plumbing license, and still needs the project-specific Engineering and Fire Code permits recorded above. A city where the contractor works may separately require its own registration, which is not covered on this county page.

Electrical Contractor License

Texas licenses no general contractor - there is no statewide builder license. Individual trades are licensed instead: electrical, plumbing and HVAC, each under its own programme. The $110 is the application fee. Published renewal figures conflict between $110 and $165 depending on license subtype, so no renewal amount is recorded until a reviewer confirms which applies.

The 2 state-level registrations apply to every type of business across TX and are covered on the TX state page.
