Austin Plumbing Permit Requirements

Last verified 2026-06-07. Sources linked at the bottom of this page.

When you DO NOT need a permit

  • Stand-alone plumbing permits (Repairs, Change Out, Irrigation, Auxiliary Water, Abandon Septic and Connect to Sewer Tap, New Construction in ETJ) do not require a formal plan review by review staff.
  • Austin maintains a separate 'Work Exempt from Building Permits' list referenced by DSD, but its contents were not included in the fetched pages and must be confirmed at the city's Work Exempt from Building Permits page.
  • Use the city's 'Do I Need A Permit?' interactive tool to confirm whether a specific project requires a permit based on jurisdiction, property type, and scope.

Required permits and forms

  • Contractor registration with City of Austin
    Must be registered as a contractor before applying for any stand-alone plumbing permit. Registration is done through the Contractor Registration webpage.
  • Plumbing permit (stand-alone trade permit)
    Austin issues separate stand-alone plumbing permit types depending on scope: Plumbing Repairs, Plumbing Change Out, Plumbing Irrigation, Plumbing Auxiliary Water, Plumbing Abandon Septic Tank and Connect to City Sewer Tap, and Plumbing New Construction in ETJ.
  • Application via AB+C Portal
    Most stand-alone plumbing permits (Repairs, Change Out, Irrigation, Auxiliary Water, Abandon Septic and Connect to Sewer Tap) are applied for through the AB+C Portal. Plumbing New Construction in ETJ uses the Stand-Alone Trade Permit Web Form.
  • Water/Wastewater Tap permit (Austin Water)
    Required separately for permanent water and/or wastewater service, permanent water meter installation, reclaimed water service line and meter, or temporary hydrant/truck-mounted water meters. Applied via AB+C Portal.
  • On-Site Sewage Facility (septic) permit
    Required for septic tank work within the City of Austin full purpose jurisdiction and annexed areas. Submit completed documents via email to OSSF.

Typical timeline

Timeline varies by project complexity; the city does not publish a typical range.

Contractor licensing

Austin requires the applicant to be registered as a contractor with the City of Austin before applying for any stand-alone plumbing permit, per the Contractor Registration webpage referenced on the Types of Permits page. The fetched pages do not state Texas state plumbing license requirements, though Texas state law (administered by the TSBPE) generally requires a state Master or Journeyman Plumber license to perform plumbing work; this is not directly sourced from the Austin pages provided.

Disclaimer: this tool reproduces publicly published permit requirements for informational purposes only. It does not constitute legal advice. Always confirm requirements with your local building department before starting work. Requirements can change without notice between our scrapes.
Scrape notes: Well-sourced: the list of stand-alone plumbing permit types, the requirement to register as a contractor before applying, the AB+C Portal as the application channel, and the DSD phone number. Gaps: the fetched pages do not include any plumbing fee schedule, review/issuance timelines in days, or a complete 'work exempt from permits' list (DSD references a separate Work Exempt page that was not fetched). Texas state plumbing license requirements are not stated on the Austin pages provided and were not extrapolated into the requirements list. Fees and timeline fields are null because the source pages are silent on those values. The second source page appears truncated in the fetch (ends mid-section on Residential Electrical), so additional residential plumbing detail beyond the Commercial Building and Trade Permits section may exist but was not captured.
