SCAG has developed and maintained its regional geospatial dataset of land use information at parcel-level—approximately five million parcels in the SCAG Region. The parcel-based land use dataset is developed (1) to aid in SCAG’s regional transportation planning, scenario planning and growth forecasting, (2) facilitate policy discussion on various planning issues, and (3) enhance information database to better serve SCAG member jurisdictions, research institutes, universities, developers, general public, etc. After the successful release of SCAG’s 2016 regional land use dataset for the development of the Connect SoCal (the 2020 RTP/SCS), SCAG has initiated a process to annually update its regional land use information at the parcel-level (the Annual Land Use Update). For the Annual Land Use Update process, SCAG collected county assessor’s tax roll records (including parcel polygons and property information) from county assessor’s offices, plus other reference layers including California Protected Areas Database (CPAD), California School Campus Database (CSCD), Farmland Mapping and Monitoring Program (FMMP)'s Important Farmland, U.S. Department of Defense's Military Installations, Ranges, and Training Areas (MIRTA) as well as SCAG's regional geospatial datasets, such as airport polygons and water body polygons.
Note: This dataset is intended for planning purposes only, and SCAG shall incur no responsibility or liability as to the completeness, currentness, or accuracy of this information. SCAG assumes no responsibility arising from use of this information by individuals, businesses, or other public entities. The information is provided with no warranty of any kind, expressed or implied, including but not limited to the implied warranties of merchantability and fitness for a particular purpose. Users should consult with each local jurisdiction directly to obtain the official land use information.

3. Decade built information is only available for Los Angeles and Ventura counties. Parcels with missing data or invalid year built information are marked as empty string.
4. Based on 2019 building footprint data obtained from BuildingFootprintUSA (except that 2014 building footprint data was used for Imperial County). Please note that 2019 building footprint data does not cover the entire SCAG region (overlapped with 83% of parcels in the SCAG Region).
5. Type of public agency includes federal, state, county, city, special district, school district, college/university, military.
6. A detailed study conducted by Cal Poly Pomona (CPP) and available here conducted an extensive review of state and local requirements and development trends for ADUs in the SCAG region and developed a baseline set of assumptions for estimating how many of a jurisdiction’s parcels could accommodate a detached ADU. Please note that these estimates (1) do not include attached or other types of ADUs such as garage conversions or Junior ADUs, and (2) are conducted without screening for site-specific topological, or other constraints, or regard for financial feasibility, or development likelihood
7. These values are intended as a rudimentary indicator of accessibility developed by SCAG using 2019 InfoUSA business establishment data.
8. The SCAG travel demand model is designed for regional planning applications, focusing on regionally significant policies, programs, and transportation investments across six counties. The model is calibrated and validated at an aggregate level, such as the county or regional scale. Directly evaluating the model output at a small geographic level, such as TAZ, roadway segment, local project area, or parcel is not within the design scope of this model and these data are provided for scenario planning or initial screening purposes only. Data are not available for parcels lying in TAZs with a residential population below 50.
