Licensing Requirements
Texas requires Master Plumber, Journeyman Plumber, and Apprentice licenses issued by the Texas State Board of Plumbing Examiners (TBPE).

Journeyman requires 4 years documented experience, pass written and practical exams. Apprentices work under licensed supervision. All licenses renew biennially. Exam costs range $100-300; license renewal approximately $175-250 per license type.
Permit Requirements
City of San Antonio requires permits for most plumbing work including new installations, alterations, repairs to main water/sewer lines, water heater installation, and drain work. Permits obtained through San Antonio's Development Services Department. Permit costs typically $50-300 depending on project scope. Final inspection required before work sign-off. Residential repairs under $500 may qualify for expedited review. Commercial work requires additional plan review and coordination with Building Code Official.
Inspection Schedule
Initial rough-in inspection before drywall closure (typically within 48 hours of request). Final inspection after all work complete and system pressure-tested. Water quality/backflow prevention devices require certification inspection. San Antonio typically schedules inspections within 3-5 business days. Failed inspections allow 10 business days for correction before re-inspection fee imposed ($75-150).

Texas does not mandate specific minimum liability insurance for plumbers, but San Antonio municipal contracts typically require $1M general liability minimum.

How to Get Licensed
Document Your Experience
For Journeyman: Accumulate 4 years of documented full-time plumbing work under a licensed plumber. For Master: Accumulate 5 years total (minimum 1 year as Journeyman, 4 years additional). Keep detailed records with employer names, dates, and type of work performed. Texas State Board of Plumbing Examiners requires verifiable documentation; use W-2s, pay stubs, or signed affidavits from supervising plumbers. Gaps or inconsistencies will trigger requests for clarification or rejection.
Complete Continuing Education (if required)
If applying for Master license and you have a current Journeyman, complete 4 hours of continuing education within the last 24 months before application. Approved CE providers include community colleges, trade organizations, and online providers. Maintain certificates of completion. This requirement applies to renewal cycles as well—failure to complete CE results in license non-renewal and inability to work.
Submit Application to Texas State Board of Plumbing Examiners
Complete the official TBPE application form (available at www.bpe.texas.gov). Include documentation of experience (work history, W-2s, affidavits), payment of application fee ($50-$100), and proof of citizenship or work authorization. For Journeyman, include proof of 4 years experience. For Master, include proof of 5 years experience and 1 year as Journeyman. Submit by mail or online through the TBPE portal. Processing typically takes 2-4 weeks. TBPE will notify you of approval or request additional documentation.
Schedule and Pass Written Exam
Once TBPE approves your application, schedule your written examination through Pearson Vue (TBPE's exam administrator). Exams are offered monthly in multiple Texas cities. Study materials are available through TBPE and trade organizations. Written exam covers plumbing code, safety, system design, and materials. Exam fee is approximately $100-$150. Passing score is 70% minimum. Results posted within 3-5 business days. You must pass written exam before scheduling practical exam.
Schedule and Pass Practical Exam
After passing written exam, schedule practical examination (also through Pearson Vue). Practical exam tests hands-on plumbing skills: installation, troubleshooting, code compliance, and safety procedures. Exam takes 4-6 hours and includes real plumbing scenarios. Fee is approximately $150-$200. You must bring your own tools. Bring identification and proof of written exam passage. Practical exams are less frequently scheduled than written; book 2-3 months in advance. Passing score is 70% minimum. Results posted within 5-7 business days.
Receive License and Maintain Compliance
Once both exams pass, TBPE issues your license (Journeyman or Master) and assigns a license number. License is valid for 24 months. You must display your license at your place of business and carry proof of licensure when working. Before renewal, complete required continuing education (4 hours every 24 months for Master; same for Journeyman). Renewal application and fee ($175-$250) must be submitted 30 days before expiration. Failing to renew on time requires reapplication and exam retake. Keep records of all CE completion and maintain professional liability insurance throughout your career.
About This Market
San Antonio's plumbing market is steady and competitive. You've got roughly 8,320 licensed plumbing establishments across Texas, and San Antonio pulls a solid share of that work. The city runs hot—literally. That means water heater replacements, burst pipes from thermal shock, and air conditioning condensate line issues year-round. Summer demand spikes hard because homeowners tackle renovations and builders push completion schedules. Competition is moderate to heavy depending on neighborhood; north San Antonio (Stone Oak, The Dominion) commands premium pricing, while south side work runs leaner margins. Residential service calls dominate, but the city's construction boom means steady commercial plumbing work on multi-family and office builds. Labor availability is decent; the median plumber in this market earns $60,778 annually ($29.22/hr), which aligns with state and national figures. Material costs run slightly higher than national average due to regional supply chain and competitive bidding.

Minor repairs may qualify for exemption if cost is under $500, but you should verify with the Development Services Department before starting work. Permits cost $50-$300 depending on project scope. Unpermitted work can result in fines, liens on property, and mandatory re-do at your expense. Always pull the permit—it protects you and the property owner.
What licenses do plumbers need in Texas and San Antonio?
Texas requires Master Plumber, Journeyman Plumber, or Apprentice licensure through the Texas State Board of Plumbing Examiners (TBPE). Master license requires 5 years experience, passing written and practical exams, and renewal every 24 months with 4 hours continuing education. Journeyman requires 4 years documented experience and exam passage. Apprentices work under licensed supervision. San Antonio enforces these requirements strictly—the city will not issue permits to unlicensed plumbers. License renewal costs approximately $175-$250 per license type.

Rough-in inspections typically schedule within 48 hours of request; final inspections within 3-5 business days. San Antonio's Development Services Department processes inspection requests online and by phone. Inspections are mandatory after rough-in work and before drywall closure, and again after final completion. If work fails inspection, you have 10 business days to correct it and request re-inspection (re-inspection may carry a $75-$150 fee). Having your documentation ready (permit, photos, pressure test results for water lines) speeds the process. Emergency inspections may be available for rush work but incur additional fees.

Workers' compensation insurance is required for any employees. Bonding requirements vary but typically run $5,000-$25,000 for contractor bonds on permit work. Residential clients often don't ask, but commercial and government work demands proof of coverage. Having $1M-$2M liability is standard industry practice and makes you competitive. Insurance costs approximately $100-$300 per month depending on business size and claims history. Check your policy exclusions—some carriers exclude certain high-risk work like mold remediation or backflow prevention device installation.
