Intermediate Length Occupancy (ILO) Dwelling Units

The owner or operator of each ILO is required to submit an annual usage report by March 1 of every year for the prior calendar year. 

The annual usage report may be submitted by email and must contain the following information:

1. The number of times the unit was occupied for a stay of greater than 30 consecutives days but less than one year.
2. The average duration of each stay.
3. The average vacancy between each stay.
4. Any amenities provided to occupants of the ILO, including, but not limited to, interior furnishings and reserved off-street parking for vehicles.

The email subject line should include:

• ILO Annual Report
• the address of the ILO (including the unit number, if applicable)
• the Planning Record Number (example: 2024-999999PRJ) assigned to the unit prior to authorization

Example: “ILO Annual Report for 123 Main Street, #1 – 2024-999999PRJ”

Annual usage reports may be emailed to: CPC.Intake@sfgov.org

Any ILO unit designation must be established through the issuance of a Planning Approval Letter with plans that document the location of the ILO units within the building, and each established ILO unit is subject to annual reporting requirements. However, as detailed below, some Dwelling units are either 1) prohibited from obtaining an ILO designation, 2) required to obtain a Conditional Use Authorization for an ILO designation, or 3) completely exempt from the ILO controls. All proposals for ILO Dwelling Units in either existing or buildings with permits issued prior to the program start date are encouraged to submit the required approval applications by June 22, 2022. After that date, to the extent that the 1,000 ILO Dwelling Unit limit is not met, ILO Dwelling Units may also be approved in new projects.

Prohibited

A Dwelling Unit is not eligible to be permitted as ILO if:

1. It is located on a lot within a Mixed Use Zoning District (i.e. Eastern Neighborhoods, Chinatown, etc.) regulated by Article 8 of the Planning Code
   (Note: Ordinance 70-23 inadvertently listed ILOs as principally permitted in some mixed-use districts, although such an amendment was not communicated or discussed as part of the review and adoption process. The Planning Department has confirmed that the intent of the Ordinance was to maintain ILOs as not permitted. Therefore, pursuant to Planning Code Sec. 307(a), ILOs will continue to be considered not permitted in mixed-use districts as a “rule/regulation.”); 
2. It is located in a building with 3 or fewer Dwelling Units;
3. It is an affordable unit subject to the Inclusionary Affordable Housing Program pursuant to Planning Code Sections 415 and/or 419;
4. It is subject to the price controls of the San Francisco Rent Ordinance (Administrative Code Section 37.3);
5. It is in a building with an active Notice of Violation from the Planning Department; or
6. If it is located within a new project that had its site or building permit issued after June 22, 2020 (effective date of the ILO program).

Conditional Use Authorization Required

For buildings with 10 or more Dwelling Units, ILO authorization requires a Conditional Use Authorization (CUA) from the Planning Commission, in addition to a Planning Approval with plans that document the location of the ILO units within the building, and is subject to the following criteria:

1. No more than 20% of the Dwelling Units in the building may be permitted as ILO units;
2. The authorized ILO units for the project do not result in more than 1/3 of the permitted 1,000 ILO units in the City falling outside the downtown core (i.e. C-3 Zoning Districts);
3. The authorized ILO units for the project do not result in more than 1/3 of the permitted 1,000 ILO units in the City falling within Census Tracts in sensitive communities, as defined by the UC Berkeley Urban Displacement Project Sensitive Communities Map.

Only a Planning Approval is Required

Up to 25% of Dwelling Units in buildings containing 4 to 9 Dwelling Units may be authorized for ILO designation through the issuance of a Planning Approval Letter with plans that document the location of the ILO units within the building. For example, an existing or proposed building containing 9 dwelling units may have up to 2 Dwelling Units authorized as ILO (standard rounding rules apply).

Exceptions

The following types of Dwelling Units are not subject to ILO restrictions and do not require any separate authorization for leases between 30 days and one year:

1. Any Dwelling Unit that is defined as Student Housing in Planning Code Section 102;
2. A Residential Hotel unit subject to the provisions of Administrative Code Chapter 41; or
3. An organization with tax-exempt status under 26 United States Code Sections1 501(c)(3) providing access to the unit in furtherance of its primary mission to provide housing, provided that any organization that provides an ILO Dwelling Unit complies with certain reporting requirements.

Annual Reporting

No later than March 1 of each year, the owner or operator of each ILO unit shall submit to the Department an Annual Unit Usage Report for the prior calendar year containing the following information:

1. The address and location of the ILO unit.
2. The number of times the unit was occupied by a natural person for an initial stay, whether through lease, subscription, license, or otherwise, for a duration of greater than 30 consecutive days but less than one year, including the duration and dates of each of those stays.
3. The average duration of each stay.
4. The average vacancy between each stay.
5. The nature of the services, if any, that are provided to occupants of the ILO units, including furnishings, or other amenities, and whether there has been an increase or decrease in the services since the last report.
