Cal. Health & Safety Code § 33487

(a) Subject to subdivisions (a) and (b) of Section 33486, not less than 20 percent of all taxes that are allocated to the redevelopment agency pursuant to Section 33670 for redevelopment projects merged pursuant to this article, irrespective of the date of adoption of the final redevelopment plans, shall be deposited by the agency in the Low and Moderate Income Housing Fund established pursuant to Section 33334.3, or which shall be established for purposes of this section. The agency shall use the moneys in this fund to assist in the construction or rehabilitation of housing units that will be available to, or occupied by, persons and families of low or moderate income, as defined in Section 50093, and very low income households, as defined in Section 50105, for the longest feasible time period but not less than 55 years for rental units and 45 years for owner-occupied units. For the purposes of this subdivision, “construction and rehabilitation” shall include acquisition of land, improvements to land; the acquisition, rehabilitation, or construction of structures; or the provision of subsidies necessary to provide housing for persons and families of low or moderate income, as defined in Section 50093, and very low income households, as defined in Section 50105.
(b) The agency may use the funds set aside by subdivision (a) inside or outside the project area. However, the agency may only use these funds outside the project area upon a resolution of the agency and the legislative body that the use will be of benefit to the project. This determination by the agency and the legislative body shall be final and conclusive as to the issue of benefit to the project area. The Legislature finds and declares that the provision of replacement housing pursuant to Section 33413 is of benefit to a project.
The Legislature finds and declares that expenditures or obligations incurred by the agency pursuant to this section shall constitute an indebtedness of the project.
(c) If moneys deposited in the Low and Moderate Income Housing Fund pursuant to this section have not been committed for the purposes specified in subdivisions (a) and (b) for a period of six years following deposit in that fund, the agency shall offer these moneys to the housing authority that operates within the jurisdiction of the agency, if activated pursuant to Section 34240, for the purpose of constructing or rehabilitating housing as provided in subdivisions (a) and (b). However, if no housing authority operates within the jurisdiction of the agency, the agency may retain these moneys for use pursuant to this section.
(d) If the agency deposits less than 20 percent of taxes allocated pursuant to Section 33670, due to the provisions of subdivisions (a) and (b) of Section 33486, in any fiscal year, a deficit shall be created in the Low and Moderate Income Housing Fund in an amount equal to the difference between 20 percent of the taxes allocated pursuant to Section 33670 and the amount deposited in that year. The deficit, if any, created pursuant to this section constitutes an indebtedness of the project. The agency shall eliminate the deficit by expending taxes allocated in years subsequent to creation of the deficit and, until the time when that deficit has been eliminated, an agency shall not incur new obligations for purposes other than those set forth in Section 33487, except to comply with the terms of any resolution or other agreement pledging taxes allocated pursuant to Section 33670 that existed on the date of merger pursuant to this article.
(e) Notwithstanding subdivision (d) of Section 33413, any agency that merges its redevelopment project areas pursuant to this article shall be subject to subdivisions (a) and (c) of Section 33413.
