Step 1: Identification of Developable Sites Government Code section 65583.2(a)
Housing Element Sites Inventory Guidebook (AB 1397) · 2026 edition · updated 2026-07-29 · California
Generally, a site is a parcel or a group of parcels that can accommodate a portion of the jurisdictions RHNA. A jurisdiction must identify, as part of an inventory, sites within its boundaries (i.e., city limits or a county’s unincorporated area)[2] that could have the potential for new residential development within the eight- or five-year timeframe of the housing element planning period.
Types of sites include:
Vacant sites zoned for residential use.
Vacant sites zoned for nonresidential use that allow residential development.
Residentially zoned sites that are capable of being developed at a higher density (nonvacant sites, including underutilized sites).
Sites owned or leased by a city, county, or city and county.
Sites zoned for nonresidential use that can be redeveloped for residential use and a program is included to rezone the site to permit residential use.
Pending, approved, or permitted development:
Projects that have been approved, permitted, or received a certificate of occupancy since the beginning of the RHNA projected period may be credited toward meeting the RHNA allocation based on the affordability and unit count of the development. For these projects, affordability is based on the actual or projected sale prices, rent levels, or other mechanisms establishing affordability in the planning period of the units within the project (See Part E). For projects yet to receive their certificate of occupancy or final permit, the element must demonstrate that the project is expected to be built within the planning period.
Definition of Planning Period: The “Planning period” is the time period between the due date for one housing element and the due date for the next housing element (Government Code section 65588(f)(1).) For example, the San Diego Association of Governments’ 6[th] Cycle Planning Period is April 15, 2021 to April 15, 2029.
Definition of Projection Period: “Projection period” is the time period for which the regional housing need is calculated (Government Code section 65588(f)(2).). For example, the San Diego Association of Governments’ 6[th] Cycle Projection Period is June 30, 2020 to April 15, 2029. End definitions
Please note, sites with development projects where completed entitlements have been issued are no longer available for prospective development and must be credited towards the RHNA based on the affordability and unit count of the development. “Completed entitlements” means a housing development or project which has received all the required land use approvals or entitlements necessary for the issuance of a building permit. This
2 In some cases, jurisdictions may want to include sites anticipated to be annexed in the planning period. Annexation is considered a rezoning effort to accommodate a shortfall of sites. For more information on annexation please see Part E, Step 3.

means that there is no additional action required to be eligible to apply and obtain a building permit.
Jurisdictions may choose to credit sites with pending projects since the beginning of the RHNA projection period towards their RHNA based on affordability and unit count within the proposed project but must demonstrate the units can be built within the remaining planning period. Affordability must be based on the projected sales prices, rent levels, or other mechanisms establishing affordability in the planning period of the units within the project.
Census definition of a unit: A housing unit is a house, an apartment, a group of rooms, or a single room occupied or intended for occupancy as separate living quarters. Separate living quarters are those in which the occupants do not live and eat with other persons in the structure and which have direct access from the outside of the building or through a common hall. Living quarters of the following types are excluded from the housing unit definition: dormitories, bunkhouses, and barracks; quarters in predominantly transient hotels, motels, and the like, except those occupied by persons who consider the hotel their usual place of residence; quarters in institutions, general hospitals, and military installations, except those occupied by staff members or resident employees who have separate living arrangements.
Student/University Housing: Please be aware, college and university student housing may be considered noninstitutional group quarters and not a housing unit for purposes of meeting the RHNA. According to the census, college/university student housing includes residence halls and other buildings, including apartment-style student housing, designed primarily to house college and university students in group living arrangements either on or off campus. These facilities are owned, leased, or managed by a college, university, or seminary or can be owned, leased, or managed by a private company or agency. Residents typically enter into “by the bed” leases (i.e., single-liability leases). Another distinguishing factor is that the unit is not available for rent to non-students. For further information on whether university housing meets the definition of a housing unit, please contact the Department of Finance at (916) 323-4086. End definitions
- Exempt entity controlled sites (state excess sites, military, university, and tribal land)
HCD recognizes that the development of new housing on exempt entity sites (land controlled by exempt federal, state, or tribal entities) can meet a portion of a jurisdiction’s RHNA. However, sites located on land controlled by exempt entities are analyzed differently because the jurisdiction may not have control over the planning, permitting, and decision-making processes of land owned by another public entity.
that the development of new housing on exempt entity sites (land controlled by exempt federal, state, or tribal entities) can meet a portion of a jurisdiction’s RHNA. However, sites located on land controlled by exempt entities are analyzed differently because the jurisdiction may not have control over the planning, permitting, and decision-making processes of land owned by another public entity.
Sites controlled by exempt entities can be used to accommodate RHNA when documentation can be provided that demonstrates the likelihood that the planned housing will be developed within the current RHNA/housing element cycle. Adequate documentation can vary due to differences in the planning processes on land controlled by exempt federal, state, or tribal entities. The following are examples of documentation that demonstrates the likelihood of housing being developed on sites outside the control of a local government. In each of these examples, the units would have to meet the U.S. Census Bureau (Census) definition of a housing unit:
