Housing Production & Capacity Portal

The Housing Production and Capacity Portal (Portal) tracks progress towards implementing the General Plan by illustrating housing production and land use capacity since 2011. The Portal answers questions like how much and where development is occurring, where are developments in the permit process located, and where there is General Plan dwelling unit capacity remaining?

The Portal results are updated quarterly and are made available on this website.

Housing Production & Capacity Portal Results

The Portal collects and aggregates information like existing number of dwelling units, changes to land use capacity, production of housing units, and remaining dwelling unit capacity of the General Plan in a series of heatmaps. The Portal results are updated quarterly and can be accessed through the Housing Production & Capacity Portal Summary, unincorporated community heatmaps, or through an online Portal Search Feature to explore remaining dwelling unit capacity of the General Plan. Portal highlights are include (updated as of 12/8/2021):

Number of Dwelling Units produced since 2011: 7,515
Number of Dwelling Units receiving discretionary permit approval since 2011: 7,865

General Plan Dwelling Unit Capacity

Dwelling unit capacity is the difference between the amount of existing development today and the likely amount allowed by the General Plan that could occur from development on vacant or developed lands within the unincorporated area. Construction of these units may or may not happen and depends on obtaining approvals from the County. Infrastructure such as roads, sewers, storm drains, and water connections may be needed. Also, site-specific conditions may limit the number of units constructed such as animal habitats, steep slopes, and flood areas; and demand for new homes.

The Portal Tracks the dwelling unit capacity and reports out results for each community planning area and unincorporated area. You can view the remaining dwelling unit capacity below by clicking on the below:

The graphic below shows the remaining general plan housing capacity by community areas. Click on each community to see a heatmap that visually shows where the remaining general plan housing capacity is located.

The unincorporated area is defined by individual subregions and community planning areas. These areas that are centered around a village, have similar geography or are divided by geographic or jurisdictional boundaries. Many are represented by the 26 Community Planning and Sponsor Groups to provide input to the Board of Supervisors on land use matters important to their community.
