Portable Generators: Best for Short Outages
Pros
- Low upfront cost ($500 – $3,000)
- No installation required
- Portable — take it camping or to job sites

- Gasoline storage is a fire hazard
Standby Generators: Best for Whole-Home Backup
Pros
- Automatic — starts within seconds of outage
- Powers entire home (or critical circuits)
- Runs on natural gas — unlimited runtime
- Quieter than portable models
- Increases home value
- No manual intervention required
Cons
- Higher upfront cost ($3,000 – $15,000 installed)
- Requires professional installation and permits
- Permanent installation — not portable
- Annual maintenance recommended
- HOA approval may be required
Generator Considerations for Los Angeles
Los Angeles has unique challenges that make standby generators especially valuable:
PSPS Events
PG&E and SCE implement Public Safety Power Shutoffs during high fire danger. These can last 2-5+ days. A standby generator keeps your home powered through extended outages.
Heat Waves
Summer heat waves strain the grid. A standby generator keeps your A/C running when you need it most — critical for elderly family members and medical equipment.
Earthquake Preparedness
After a major earthquake, power restoration could take days or weeks. A standby generator with natural gas provides reliable backup when the grid is down.
Generator FAQ
What is the difference between a portable and standby generator? +
A portable generator is a temporary, movable power source that runs on gasoline or propane. A standby generator is a permanent, automatic system installed outside your home that runs on natural gas or propane and activates within seconds of a power outage.
How much does a standby generator cost in Los Angeles? +
Standby generators cost $3,000-$15,000 installed, depending on size and fuel type. A typical 20kW whole-home generator runs $8,000-$12,000 installed with transfer switch.
Can I install a standby generator myself? +
No. Standby generator installation requires a licensed electrician and plumber. LADBS requires permits for both the electrical transfer switch and gas connection. Our C-10 license handles the electrical side.
How long do portable generators last? +
Portable generators typically last 10-20 years with proper maintenance. However, they require regular oil changes, fuel stabilization, and periodic test runs.
Do standby generators require maintenance? +
Yes. Standby generators need annual maintenance including oil changes, filter replacement, and test runs. We offer maintenance plans to keep your generator ready.
