Scope of practice is the boundary of what your particular license authorizes you to do. TDLR licenses are not generic permission to work in a trade — each license type defines specific work, and exceeding it is a violation even when the license is active and in good standing. Examples across the trades:
- Class B ACR contractor: limited to cooling systems of 25 tons and under and heating systems of 1.5 million BTU/hour and under. Working on a larger system with only a Class B license violates Texas Occupations Code Chapter 1302 — a Class A license has no tonnage or BTU limits
- Residential Wireman: electrical work on residential properties only — single-family homes, duplexes, and similar dwellings. Commercial and industrial work requires a Journeyman or Master license
- Cosmetology specialty licenses: an esthetician license covers skin care services such as facials, waxing, and makeup — not haircutting or nail services, which belong to other license types
Scope violations are enforcement matters like any other: they can draw administrative penalties and discipline, and they often surface through customer complaints or permit inspections.
What it means for your renewal
Know your license's limits before quoting a job, and upgrade the license before taking work beyond them — for ACR contractors that's the Class A vs. Class B decision; for electricians it's the Residential Wireman vs. Journeyman ladder. CE keeps your license active, but only the right license class makes the work legal.
