Program Description and Application Instructions

California Advanced Services Fund (CASF) promotes deployment of high-quality advanced communications services to Californians.

Funding is allocated to four CASF accounts (please go to the linked page for a description of the account):

Annual Right Of First Refusal (ROFR) Demonstration Letter

The Right of First Refusal (ROFR) Resolution T-17590 does not prohibit existing providers from submitting the ROFR letter indicating an intent to build in a given area beyond the 180 days and before the next ROFR process begins. However, Commission receipt of the letter will not bar the Commission from approving a grant to build in the same area.

Background and History

The Commission authorized the California Advanced Services Fund (CASF) on December 20, 2007, by adopting D.07-12-054 in accordance with Public Utilities (P.U.) Code § 701. The CASF provides grants to “telephone corporations” as defined under P.U. Code § 234 to bridge the “digital divide” in unserved and underserved areas in the state. With an initial funding of $100 million, the CASF supports projects that will a) provide broadband services to areas currently without broadband access and b) build out facilities in underserved areas, if funds are still available.

The Commission adopted the CASF application requirements, timelines, and scoring criteria for parties to qualify for broadband project funding in Resolution T-17143 issued on June 12, 2008. The Legislature reaffirmed the Commission’s creation of the CASF program in Senate Bill (SB) 1193, which Governor Schwarzenegger signed on September 27, 2008, and codified the program as Public Utility Code § 281.

On September 25, 2010, Governor Schwarzenegger signed SB 1040 (Chapter 317, Stats 2010), which provided an additional $125 million, allocated to the following CASF accounts: $100 million to the Broadband Infrastructure Grant Account, $10 million to the Rural and Regional Urban Consortia Account, and $15 million to the Broadband Infrastructure Loan Account.

To implement the provisions of SB 1040 and improve the program based on CASF’s three year implementation experience, the Commission opened an Order Instituting Rulemaking (R.10-12-008) on December 16, 2010.

On June 28, 2011, the Commission approved D.11-06-038 to implement the Rural and Urban Regional Broadband Consortia grant program to help fund activities promoting broadband deployment, access, and adoption with a budget of $10 million.

Recent Legislation

On November 1, 2012, the Commission issued Order Instituting Rulemaking (OIR) 12-10-012, which proposed to extend CASF applicant eligibility to facility-based broadband service providers that hold neither a CPCN nor WIR. The OIR further proposed to extend CASF eligibility to any commercial provider of broadband access or any nonprofit entity, including government entities or community anchor institutions that elect to provide facilities based broadband service.

The OIR acknowledged that any change in eligibility requirements was contingent upon legislative action because these requirements are defined in statute. During the 2013-2014 Legislative Session, the Legislature passed SB 740 to expand eligibility. The legislation requires that the Commission give priority to last mile projects serving unserved households, that newly eligible non-CPCN/ WIR holders must provide a last mile connection to an unserved household, that the CPUC must give existing providers the opportunity to upgrade their networks in areas serving underserved households before funds are awarded to a new provider, and that local governments may apply for funds only if its project provides a connection to an unserved household or business and no other eligible entity has applied.

Additionally, during the 2013-2014 Legislative Session, the Legislature passed AB 1299. AB 1299 created an additional account under the CASF called the Broadband Public Housing Account to support projects to deploy local area networks and to increase adoption rates in publicly supported housing communities. These efforts will be funded through $20 million from the CASF Broadband Infrastructure Account and $5 million from the Revolving Loan Account, respectively.

On October 15, 2017, Governor Brown signed AB 1665, which amends Pub. Util. Code Sections 281 and 914.7 to extend the date of the CASF goal from 2015 to 2022 and modify the goal to approve funding for broadband infrastructure projects that will provide broadband access to no less than 98 percent of California households in each consortia region, as identified by the commission on or before January 1, 2017. AB 1665 revises eligibility requirements for Broadband Infrastructure Account and creates a Right of First Refusal process and a Line Extension program. It also creates the Broadband Adoption Account and eliminates the Loan Account. 



On February 27, 2014, the Commission approved D14-02-018 which amends the eligibility rules for the CASF Program according to the definition of eligibility in SB 740. It gives the Commission the authority to enforce the terms and conditions of the grant awards and to impose penalties under P.U. Code §§ 2111 and 2108.

Resolution T-17443 (approved June 26, 2014) implements new timelines for applicants to CASF, including how and when local government agencies and non-telephone corporations may apply pursuant to Senate Bill (SB) 740. It also describes how existing providers may exercise their right of first refusal as provided under SB 740. In addition, this Resolution lists areas in California that various CASF-funded regional consortia groups and state agencies have identified as priorities for broadband infrastructure deployment.

On December 18, 2014, the Commission approved D14-12-039 which implements (SB) 1299 and adopts the CASF Broadband Public Housing Account, establishing application requirements and guidelines. 



The CASF is funded by a surcharge rate on revenues collected by telecommunications carriers from end-users for intrastate telecommunications services. On January 1, 2008, the Commission adopted a surcharge rate of 0.25% to fund the program. On December 17, 2009, the Commission approved Resolution T-17248 which reduced the CASF surcharge from 0.25% to 0.00% effective January 1, 2010. To collect the additional funds authorized by SB 1040, the Commission issued Resolution T-17343 on September 22, 2011, which revises the surcharge from 0.0% to 0.14% effective November 1, 2011. The Commission approved Resolution T-17386 on February 13th, 2013, increasing the surcharge rate from 0.14% to 0.164% effective April 1, 2013. The Commission approved Resolution T-17434 on February 27th, 2014, increasing the surcharge rate from 0.164% to 0.464% effective April 1, 2014. The Commission approved Resolution T-17536 on October 13, 2016, decreasing the surcharge rate from 0.464% to 0.00% effective December 1, 2016. The Commission approved Resolution T-17593 on December 14, 2017, which adopts a surcharge rate increase from 0.00% to 0.56% effective March 1, 2018, and thereafter, until December 31, 2022.
