Texas Handyman Limitations Most states put a financial limit on what you can do without a contractor's license – usually limiting jobs to $500, $1,000, or even $3,000. However, in Texas, that isn't the case. There are currently no limits on job size for unlicensed contractors.
Hire contractors who are licensed and insured. Texas does not require general contractors to be licensed or bonded, but they are required to be a state-registered business.
