Plenty of electricians are good in a house. Fewer are just as good in a restaurant, an office suite or a warehouse, where the power is three-phase, the energy code is stricter, and every hour of downtime costs money. If you own a home and a business, or manage property, one certified contractor who handles both can save you time, paperwork and repeat site visits—whether you need routine commercial maintenance or guidance on what to do when your home loses power. These five California electricians do both well.
Home job or business job? What changes
| Residential | Commercial | |
| Power | Mostly single-phase, 100–400 amp service | Often three-phase, higher loads |
| Code focus | California Electrical Code, GFCI/AFCI protection | Code plus Title 24 energy rules for lighting and controls |
| Permits | Panel, circuits, EV chargers, rewiring | Nearly all work, plus tenant-improvement plans |
| Scheduling | Around family routines | Around business hours, to limit downtime |
| Typical jobs | Panels, rewiring, EV chargers, lighting | Tenant improvements, LED retrofits, dedicated equipment circuits |
A contractor that works on both sides should be comfortable with every row of this table.

Before a commercial electrical job: a manager’s checklist
- Confirm the scope in writing, including any tenant-improvement plans your landlord or city requires.
- Ask about Title 24. New or altered lighting in California commercial spaces must meet state energy rules for controls and efficiency.
- Plan the shutdown. Agree on when power will be off, and schedule it outside business hours if you can.
- Check capacity. New equipment, kitchens or EV chargers may need three-phase service or a panel upgrade.
- Verify bonding and insurance. Many commercial landlords require proof of both before work starts.
- Book the inspection early, so it doesn’t hold up your reopening.
Why one contractor for both can pay off
Using the same certified contractor for your home and your business means one set of records, one relationship and fewer first-visit diagnoses. The contractor already knows your panels, your loads and your permit history. Just make sure its commercial experience is real: ask for two recent commercial jobs similar to yours.
Owner and manager questions
Do residential and commercial electricians need different licenses?
No. In California, the C-10 electrical contractor license covers both. The difference is experience: commercial work often involves three-phase power, heavier loads, Title 24 energy rules and tenant-improvement plans. Ask about recent commercial projects before hiring for one.
What is a tenant improvement?
A tenant improvement is a build-out or remodel of a commercial space for a new or existing tenant, such as adding circuits, lighting or equipment for a restaurant or office. It usually needs plans, permits and inspections, and the landlord may set its own requirements.
Can commercial electrical work be done after hours?
Often, yes. Many contractors schedule shutdowns early, late or on weekends to avoid disrupting a business. After-hours labor can cost more, so ask for the rate and weigh it against lost trading time.
How do I check a commercial electrician’s credentials?
Look up the C-10 license on the CSLB website, then ask for a certificate of insurance and proof of bonding. For larger projects, ask for references from similar commercial jobs.
Conclusion
The best contractor for both homes and businesses is certified, experienced on each side, and clear about pricing. Blue Moon Electrical leads for all-round residential and small-business work across California, and Electrical Land for round-the-clock service with written, pre-approved pricing. Image Electric, Wells Electrical and Leone Electric bring deeper commercial reach in LA and Orange County, the Bay Area and the Long Beach area.
Match the contractor to the size of your commercial job, check the license and bonding, and get the scope in writing before any power goes off.
