Real property tax: welfare exemption: moderate-income housing.

Existing property tax law, pursuant to constitutional authorization, provides for a "welfare exemption" for property used exclusively for religious, hospital, scientific, or charitable purposes and that is owned or operated by certain types of nonprofit entities, if certain qualifying criteria are met. That law provides a partial welfare exemption in the case of residential rental property used for lower income households, as specified, calculated as that percentage of the value of the property that is equal to the percentage that the number of units serving lower income households represents of the total number of residential units.
