Accessory Dwelling Unit Ordinance (Secondary Dwellings)

On May 25, 2017, the San Luis Obispo County Board of Supervisors approved Phase I of the Accessory Dwelling Unit Ordinance.  The Phase I amendment, which brought the County’s Land Use Ordinance into compliance with California State Code Section 65852.2 regarding Accessory Dwelling Units, eliminated County requirements for road surfacing and owner-occupancy for secondary dwellings.

Airport Land Use Plan Update

The San Luis Obispo County Airport Land Use Commission (ALUC) is in the process of a comprehensive update to the airport land use plan for the San Luis Obispo County Regional Airport. The existing plan was prepared in 2004 and is not consistent with the guidelines contained in the latest California Airport Land Use Planning Handbook, updated in 2011.

The Final Public Hearing Draft of the ALUP Update is now available.  The County has also completed a Mitigated Negative Declaration for the project.  The Airport Land Use Commission will hold a special meeting on May 26, 2021 for potential action on the Final Public Hearing Draft.

Diablo Canyon Nuclear Power Plant Decommissioning

In 2016, PG&E decided not to renew the Nuclear Regulatory Commission licenses for the Diablo Canyon Nuclear Power Plant. As a result, the power plant will cease operating upon the expiration of the Unit 1 and Unit 2 operating licenses, in November 2024 and August 2025, respectively. PG&E then intends to begin decommissioning the power plant. PG&E's land use application submitted to the County on March 29, 2021 is for the decommissioning effort.

Elements & Mitigation Plan Update

These project updates will utilize the latest updated hazard mapping resources, consistent with state law and federal requirements, and will lead to the implementation of effective mitigation projects and climate adaptation strategies. The County and its jurisdictions will utilize this new Multi-Jurisdictional Local Hazard Mitigation Plan (LHMP) and Safety Element Update to address hazards in a coordinated effort using a whole community approach that will be built on the public’s participation in the planning process.

As part of the planning process, other local agencies, neighboring jurisdictions, and stakeholders are involved to raise awareness of this effort and provide an opportunity for input. In addition, an objective of this outreach is to coordinate with those who may bring additional information to the planning process regarding hazard issues or hazard mitigation efforts within the County.

Housing Element Update (2020-2028 Housing Element)


As one (1) of the required elements of the County of San Luis Obispo General Plan, the Housing Element is the overarching strategic housing plan for the unincorporated county. It serves four (4) main purposes:

  1. Establish Framework. Provide the framework to facilitate housing development and address current and projected housing needs. This framework will shape how the unincorporated county will grow, from a housing standpoint, through 2028. The framework comprises the Housing Element goal, objectives, policies, and programs.
  2. Assess Housing Needs. Provide an assessment of the housing needs for the unincorporated county, along with information on demographics, trends, and other housing-related data.
  3. Report on Progress. Report on the County’s progress in implementing the programs of the previous Housing Element (2014-2019 Housing Element).
  4. Qualify for Funding. Qualify the County for certain funding programs offered by the State of California. This requires the Housing Element to satisfy State Housing Element Law and achieve State certification. The process includes addressing the unincorporated county’s share of the Regional Housing Needs Allocation and establishing an inventory of sites for potential housing development.

Although each local government within San Luis Obispo County – the unincorporated county and each of the seven (7) incorporated cities – has its own Housing Element to address housing needs within their respective jurisdictional boundaries, the County and the incorporated cities have been working together to apply a coordinated regional approach to addressing housing needs throughout San Luis Obispo County. In addition to working with the incorporated cities, the County is seeking input from the public, stakeholders, and industry professionals, such as the Housing Coalition, to develop this Housing Element.


The unincorporated county setting is dynamic and the demand for housing continues to increase. As such, the framework needs to adapt in order to properly serve current and future residents of the unincorporated county. The Housing Element update process allows the public, stakeholders, developers, decision makers, and staff to work together to develop a framework that achieves this purpose.

Generally, the State requires the Housing Element to be updated every eight (8) years. This Housing Element will guide planning, development, and funding related to housing, through December 2028. At the end of this eight (8) year planning period, the Housing Element will be updated once again.

Los Osos Community Plan Update

The Department of Planning & Building was authorized to update the Los Osos Community Plan of the County’s General Plan and Local Coastal Plan on December 11, 2012.

The Community Plan is the official plan for land use and transportation in Los Osos which determines how the community will grow and develop over the next 20 years. The update will focus on protecting resources and providing adequate infrastructure.


The Board of Supervisors Adopted Plan is now available for public review: 


Los Osos Habitat Conservation Plan (HCP)

The County is seeking a programmatic incidental take permit from the US Fish and Wildlife Service.  The County, as the applicant, is requesting a permit term of 25 years to authorize take of covered species associated with covered activities in the Habitat Conservation Plan area, which is approximately 3,560 acres bounded by the Los Osos Urban Reserve Line. As the permittee, the County will have the ability to issue certificates of inclusion to confer incidental take coverage to landowners and other entities as long as their activities are included on the incidental take permit(s).

Further updates will be posted and/or linked on this page as available.

Oster/Las Pilitas Quarry

A request by Las Pilitas, LLC for a Conditional Use Permit and Reclamation Plan to allow for a new aggregate quarry and asphalt and concrete recycling facility. Mining operations would occur over a 30-year timeframe and conclude with reclamation of the site. The maximum annual extraction would be 500,000 tons. The project would result in disturbance of roughly 60 acres on two parcels totaling 203 acres in size. The project site is located east of the community of Santa Margarita at 6660 Calf Canyon Highway (Highway 58, north side), east of the Salinas River Bridge and approximately 0.25 miles west of Parkhill Road.

Phillips 66 Santa Margarita Remediation EIR

The Department of Planning & Building is currently working on the Phillips 66 Santa Margarita Remediation Environmental Impact Report.

The Final Enviromental Impact Report (FEIR) and Notice are now available for public review: 


Sign Ordinance Update

The Sign Ordinance Update is a targeted effort to revise the County’s sign regulations to comply with federal law and protect the constitutional right of free speech. In 2015, the U.S. Supreme Court Case Reed v. Town of Gilbert required local jurisdictions to be content-neutral when regulating signs (for example, not regulating a sign based on whether it carries a commercial, political, or ideological message). The Sign Ordinance Update will ensure the County’s regulations uphold constitutional speech, while also protecting the visual character of the community.

The Sign Ordinance Update was approved by the Board on August 18th, 2020. Amendments to Title 22 are effective September 18th, 2020. Amendments to Title 23 are awaiting a Coastal Commission hearing for a final decision.
