Can I do my own electrical work in California?

A homeowner improving their principal residence is exempt if the work is done before sale, they have lived there for the 12 months before the work is finished, and they have not used this exemption on more than two structures more than once in any three year period. An owner who does all the work personally, or with employees paid wages only, and does not offer the improvements for sale is also exempt (B&P 7044). (source: California Legislature)
Proof that you sold or offered the property for sale within one year after finishing is presumed to show the work was for sale (B&P 7044). (source: California Legislature)

What CSLB says owner-builders take on
- When you sign a building permit application as an owner-builder, you assume full responsibility for all phases of your project and its integrity. You must pull all building permits, and your project must pass codes and building inspections.
- If you use anyone other than a licensed subcontractor, you may be considered an employer, with tax, workers' compensation, disability insurance and unemployment duties.

Owner-builder risks
- Subcontractors and suppliers who are not paid on schedule may file mechanics liens against your property.
- If your workers are injured, or your subcontractors are not licensed or insured and they are injured, you could be asked to pay through your homeowner's insurance policy or face lawsuits.
