Why standby generator installation comes up in Mobile
After Hurricane Sally in 2020 left much of Mobile without power for days, many families added standby generators with automatic transfer switches. Units should sit on raised platforms above expected flood levels, especially near the bay and in low-lying parts of west Mobile, and enclosures should be built for salt air. Natural gas from Spire serves many neighborhoods; elsewhere, propane tanks are common.
Sizing for central air is a frequent choice given the heat. Alabama Power owns the electric service, and permits inside city limits come from the City of Mobile's central permitting office.
- After Katrina's surge reached downtown in 2005 and Sally's long outages in 2020, many homeowners mount standby generators on raised platforms above expected flood levels, with corrosion-resistant enclosures near the bay.

How the work is done
1. Load and site review
The electrician decides which circuits to back up, sizes the unit, and picks a compliant spot outdoors.
2. Permits and fuel
Electrical and, often, gas or propane permits are pulled, and the fuel supply is checked for capacity.
3. Install unit and transfer switch
The pad, generator, automatic transfer switch and wiring are installed; a gas fitter connects the fuel.
4. Inspection and startup
The work is inspected, the unit is started, and the transfer is tested.
What moves the price in Mobile

Standby Generator Installation in Mobile: questions
Do I need a permit for standby generator installation in Mobile?
Usually, yes. Inside city limits, electrical permits come from the City of Mobile's central permitting office; unincorporated Mobile County has its own process. Alabama licenses electricians through the Electrical Contractors Board. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Mobile?
If the work affects the meter or service, the electrician coordinates with Alabama Power, which owns the meter and service drop.
What size standby generator do I need?
It depends on what you want to run. Essential circuits may need a smaller unit; whole-house backup with central air needs more. A load calculation decides.
Standby or portable generator?
A portable generator with an inlet and interlock costs less but has to be set up and refueled by hand. A standby unit starts and switches over by itself.
Can a standby generator run on propane?
Yes. Most run on natural gas or propane; the fuel supply must be sized for the unit.
How close to the house can it go?
Manufacturers and local codes set clearances from windows, doors, vents and property lines; the installer follows both.
