Sacramento Solar Permit Requirements 2026: City, County, and SMUD vs. PG&E Guide
Everything solar contractors need to know about solar permits in the Sacramento area — City of Sacramento requirements, surrounding cities, SMUD vs. PG&E interconnection, and 2026 timelines.
Everything solar contractors need to know about solar permits in the Sacramento area — City of Sacramento requirements, surrounding cities, SMUD vs. PG&E interconnection, and 2026 timelines.
The Sacramento area is one of California's most active and growing solar markets. Strong sun, rising utility rates, and a large, growing housing stock create consistent solar demand across the City of Sacramento and surrounding communities. For contractors expanding from coastal markets or building a Central California operation, the Sacramento area offers strong economics with permit timelines that are generally better than Southern California's Inland Empire.
Sacramento area jurisdiction map: who permits what
The Sacramento area has multiple permit authorities depending on the project address:
- City of Sacramento: Handles permits for addresses within city limits. Uses an online permit portal.
- Sacramento County: Handles unincorporated areas only — not any incorporated city.
- Roseville: Independent city in Placer County — permits go through Roseville Building Division.
- Elk Grove: Independent city — permits go through Elk Grove Building Division.
- Folsom: Independent city in El Dorado/Sacramento County border — permits through Folsom Building Division.
- Rancho Cordova: Independent city — separate from Sacramento County.
Always verify jurisdiction before submitting. Submitting a Roseville project to Sacramento County is sending it to the wrong authority.

SMUD vs. PG&E: the Sacramento utility split
This is the most important Sacramento-specific issue for solar contractors. The Sacramento area is divided between two utility service territories:
SMUD (Sacramento Municipal Utility District) serves the City of Sacramento and many surrounding areas. SMUD has its own NEM interconnection program, separate from PG&E. SMUD's NEM program has different rates, different application forms, and a different interconnection timeline than PG&E's program.
PG&E serves Roseville, Folsom, parts of Elk Grove, and other surrounding areas. PG&E NEM 3.0 applies in these areas.
The boundary between SMUD and PG&E territory is not obvious from looking at a map — it can change street by street in some areas. The only reliable way to determine which utility serves a specific address is to look up the address on SMUD's service territory map or call SMUD/PG&E directly.
Submitting to the wrong utility is a costly mistake: Submitting a SMUD NEM application for a PG&E property (or vice versa) requires starting the interconnection process over from scratch. This mistake adds 6–10 weeks to project completion. Always verify utility before starting the interconnection application.
