Do I need a solar permit in Elk Grove? Yes: SMUD's letter first, three-day review or SolarAPP+, and the state fee cap

Two routes to the permit

Sources: the City's Residential Solar Photovoltaic Permit and SolarAPP+ pages, read 23 October 2026. SolarAPP+ projects may include "up to 400A main service, 225A service disconnect switches and 225A busbars"; batteries go through a separate solar-and-storage training path, so ask your installer which route a solar-plus-battery job takes. The City's SolarAPP+ page also says, in its FAQ, that there is no total wattage limit, which conflicts with the 38.4 kW figure; confirm with the City if your system is large.

The standard route, step by step

1. Get SMUD's approval letter. The City says an "Approval letter from the Sacramento Municipal Utility District (SMUD) is required prior to submitting". SMUD's solar team: (916) 732-6420.
2. Combine one PDF. "Combine the SMUD letter, specifications, and construction plans into a single PDF", with a complete set of construction plans.
3. Register and apply. Contractors register through the City's licensed contractor form; members of the public use eTRAKiT's general registration. Pay the plan review or permit fee in eTRAKiT.
4. Plan review. At least three business days for the first review of a system up to 38.4 kW.
5. Inspection. "You must have the building permit, approved plans, and any supporting documents available for the building inspector." Inspections are scheduled from the eTRAKiT dashboard (Minor Residential Building Permits).

What the fee can be

The City's solar pages list no dollar amount. California's Government Code §66015 (read 23 October 2026) caps what a city may charge for a residential rooftop solar permit at "four hundred fifty dollars ($450) plus fifteen dollars ($15) per kilowatt for each kilowatt above 15kW", effective 1 January 2024 and in force until 1 January 2034. A city may charge more only if it adopts a written finding, by resolution or ordinance, that its reasonable cost is higher. For any system of 15 kW or less that cap is $450; whether Elk Grove charges less is something the eTRAKiT invoice will show.

Who should install it

CSLB's C-46 Solar classification, or a C-10 electrical contractor, covers solar; a B general contractor can submit SolarAPP+ jobs too. Check the license on CSLB's Check a License. More in the Elk Grove contractor license lookup.

What 3,735 Elk Grove solar permits show

Two cautions on reading this. Production homebuilders pull solar permits on the new houses they build, and two are among the five busiest solar filers, so the file mixes builder installs with retrofits. The usual filed value, $9,234, also sits below the middle half of firms' usual values, because the busiest filers write lower values on their permits than most smaller firms do; treat it as a floor, not a price. And Elk Grove solar permits almost always close: 96.1% of those a year or more old were finaled, so an installer with open permits stands out. Prices by system value are on the Elk Grove solar cost page; national figures in solar panel installation cost.

What this does not tell you

Elk Grove permits carry no license number, so our CSLB match is by business name and phone; 13.0% of solar firms did not match, which is our gap, not proof they are unlicensed. The City's site blocks automated reading, so its pages were read through a page reader. SMUD's interconnection approval is a separate step our file does not cover.
