SLO Regional Building Permit Data Summary Report (2000-2018)

SLOCOG staff has collected building permit data from the eight local jurisdictions in San Luis Obispo County. The data collection efforts were in the form of four separate surveys over nine years, which has resulted in a single georeferenced (GIS) dataset of residential and non-residential building permits covering years 2000 to 2018. SLOCOG conducted these surveys in 2007, 2011, 2015 and 2019; and partnered with SLO County Air Pollution Control District (APCD) on the two latter surveys. In 2015, SLOCOG staff embarked on a significant data collection effort to build a better picture of housing prices by type of housing, with an over-arching goal to identify estimated housing price by type of housing and by community. home price estimate data was collected for over 70,000 homes; data was then linked to those homes that were built between 2000 and 2014. The building permit data summary report for 2000 to 2014 is available here. For more information on the 2000 to 2018 Building Permit data, please contact Ritu Muralidharan at


Regional Definition of Disadvantaged Communities

The SLOCOG board approved the Disadvantaged Communities Assessment on June 2, 2021, for use in the 2023 RTP and the 2022 Programming Cycle. Creating a regional definition of disadvantaged communities for the San Luis Obispo region allows SLOCOG to better compete for grant funding, distribute funds more equitably, and meet the state and federal environmental justice requirements.
