Permit Fee Limitations

Two bills signed in 2012 (AB 1801 and SB 1222) place limits on the fees that cities, counties, cities and counties, and charter cities can charge for a solar permit. CA Government Code § 65850.55 specifies that a local government cannot base the fee for a solar permit on the value of the solar system or the value of the property on which the system will be installed. It also requires the local government to separately identify every fee charged on the invoice provided to the applicant. 

CA Government Code § 66015 restricts a city, county, city and county, or charter city from charging more for a solar permit than the estimated reasonable cost of providing the service for which the fee is charged. The law further provides specific limits on the dollar amount local governments may charge for a permit:

  • Residential photovoltaic systems: $450, plus $15 for every kilowatt (kW) over 15 kW
  • Residential solar thermal systems: $450, plus $15 for every kilowatt thermal (kWth) over 10 kWth
  • Commercial photovoltaic systems: $1,000 for systems up to 50 kW, plus $7 for every kW between 51 kW and 250 kW, plus $5 for every kW over 250 kW
  • Commercial solar thermal systems: $1,000 for systems up to 30 kWth, plus $7 for every kW between 30 kWth and 260 kWth, plus $5 for every kWth over 260 kWth

The law gives local governments the ability to exceed these cost limits by resolution or ordinance if they provide substantial evidence of the reasonable cost to issue the permit, and meet other criteria. 

Expedited Permitting 

AB 2188 (CA Government Code § 65850.5) of September 2014 required all city, county, and city and county governments to adopt an ordinance that creates an expedited streamlined permitting process for small residential rooftop solar energy systems. In developing an expedited permitting process, the city, county, or city and county must provide a checklist of all requirements for small rooftop solar energy systems to comply with to be eligible for expedited review.
