The Assessor’s Office manages programs authorized in State law to address the special valuation of affordable housing. Eligible properties may apply for both the Affordable Housing Special Assessment Program and the LIHTC valuation program.
Affordable Housing Special Assessment Program
The Affordable Housing Special Assessment Program incentivizes the rehabilitation and new construction of multi-family residential properties to create and maintain affordable housing. This program establishes assessment reductions for multifamily rental developments subjected to certain rent, tenant income, and related restrictions.
If you are the owner of an affordable housing project and seek assessment under this special assessment program, you must complete the form applications. To receive the special assessment on the 2023 tax bill for the 2022 assessment year, eligible applicants should submit parts 1 and 2 of the application no later than January 31 of the same assessment year.
Please note, the Rental Information/Tenant Household Income Report Form included in Part 2 of the Eligibility has a limit of 25 units. If your project has more than 25 units, please download the excel version (go to the file drop-down menu, click download, choose excel) and upload it as part of your attachments corresponding to the Required Documentation section in part 2 of the application. For an example of a completed Rental Information/Tenant Household Income Report Form, download here.
