Generator Installation Cost by State (2026)
National Baseline (Installed)
Most homeowners land somewhere in the broad “installed” range of roughly $7k–$16k depending on size and complexity, with many sources quoting typical projects in the $8k–$16k band (generator + installation).
- Typical installed range: $8,000–$16,000 (generator + install) is commonly cited by manufacturers and large providers.
- Install-only (not including generator): often $5,000–$10,000 on complex jobs (site specifics vary).
- Labor component: often ~$1,500–$5,000 for many installs (can be higher if trenching/gas upgrades are needed).

What Drives Price (Fast)
- Generator size (kW) + whether you’re running A/C, well pump, electric range, etc.
- Transfer switch location + panel upgrades (if needed).
- Fuel work: gas line sizing, regulators, propane tank placement.
- Trenching / conduit runs (distance matters).
- Permits + inspections (electrical + sometimes mechanical/gas/plumbing).
Permitting often involves staged inspections (rough/electrical/final) depending on jurisdiction and fuel work.
Permits & Inspections Checklist (Don’t Skip This)
- Electrical permit is commonly required for hardwired standby generator + transfer switch work.
- Gas / mechanical permit may apply if a new gas line is installed or modified.
- Typical inspection sequence: rough (trenches/conduit/gas), electrical (wiring/ATS), final (startup + clearances).
- Clearances must meet code and manufacturer placement requirements.
Always follow your local AHJ (Authority Having Jurisdiction) and manufacturer instructions; permitting and inspection steps vary by city/county.
How We Estimate These Ranges (Transparent)
The table uses a simple labor-tier model anchored to commonly cited national installed ranges. Manufacturer guidance often cites $8k–$16k installed, while large retailers and pricing guides show overlapping ranges depending on job type.
- Low: $7,000–$13,000
- Typical: $8,000–$16,000
- High: $10,000–$20,000
- Very High: $12,000–$25,000
These are budget ranges, not quotes. Final pricing depends heavily on distance runs, panel work, fuel upgrades, and permitting.
