Cal. Welf. & Inst. Code § 366.21
(e)
(f)
(1) The permanency hearing shall be held no later than 12 months after the date the child entered foster care, as that date is determined pursuant to Section 361.49. At the permanency hearing, the court shall determine the permanent plan for the child, which shall include a determination of whether the child will be returned to the child’s home and, if so, when, within the time limits of subdivision (a) of Section 361.5. After considering the relevant and admissible evidence, the court shall order the return of the child to the physical custody of their parent or legal guardian unless the court finds, by a preponderance of the evidence, that the return of the child to their parent or legal guardian would create a substantial risk of detriment to the safety, protection, or physical or emotional well-being of the child. The social worker shall have the burden of establishing that detriment.
(g) If the time period in which the court-ordered services were provided has met or exceeded the time period set forth in subparagraph (A), (B), or (C) of paragraph (1) of subdivision (a) of Section 361.5, as appropriate, and a child is not returned to the custody of a parent or legal guardian at the permanency hearing held pursuant to subdivision (f), the court shall do one of the following:
(1) Continue the case for up to 6 months for a permanency review hearing, provided that the hearing shall occur within 18 months of the date the child was originally taken from the physical custody of their parent or legal guardian. The court shall continue the case only if it finds that there is a substantial probability that the child will be returned to the physical custody of their parent or legal guardian and safely maintained in the home within the extended period of time or that reasonable services have not been provided to the parent or legal guardian, or in the case of an Indian child, that active efforts as defined in subdivision (f) of Section 224.1 have not been made by the agency. For purposes of this section, in order to find a substantial probability that the child will be returned to the physical custody of their parent or legal guardian and safely maintained in the home within the extended period of time, the court shall be required to find all of the following:
(C) The parent or legal guardian has demonstrated the capacity and ability both to complete the objectives of their treatment plan and to provide for the child’s safety, protection, physical and emotional well-being, and special needs.
(3) For purposes of paragraph (2), in order to find a substantial probability that the child will be returned to the physical custody of their parent or legal guardian and safely maintained in the home within the extended period of time, the court shall find all of the following:
(5) Order that the child remain in foster care, but only if the court finds by clear and convincing evidence, based upon the evidence already presented to it, including a recommendation by the State Department of Social Services when it is acting as an adoption agency or by a county adoption agency, that there is a compelling reason for determining that a hearing held pursuant to Section 366.26 is not in the best interests of the child because the child is not a proper subject for adoption and has no one willing to accept legal guardianship as of the hearing date. For purposes of this section, a recommendation by the State Department of Social Services when it is acting as an adoption agency or by a county adoption agency that adoption is not in the best interests of the child shall constitute a compelling reason for the court’s determination. That recommendation shall be based on the present circumstances of the child and shall not preclude a different recommendation at a later date if the child’s circumstances change. On and after January 1, 2012, the nonminor dependent’s legal status as an adult is in and of itself a compelling reason not to hold a hearing pursuant to Section 366.26. The court may order that a nonminor dependent who otherwise is eligible pursuant to Section 11403 remain in a planned, permanent living arrangement.
(i)
(1) Whenever a court orders that a hearing pursuant to Section 366.26, including, when, in consultation with the child’s tribe, tribal customary adoption is recommended, shall be held, it shall direct the agency supervising the child and the county adoption agency, or the State Department of Social Services when it is acting as an adoption agency, to prepare an assessment that shall include:
(C)
(H) In the case of an Indian child, in addition to subparagraphs (A) to (G), inclusive, an assessment of the likelihood that the child will be adopted, when, in consultation with the child’s tribe, a tribal customary adoption, as defined in Section 366.24, is recommended. If tribal customary adoption is recommended, the assessment shall include an analysis of both of the following:
(2)
(l) For purposes of this section, evidence of any of the following circumstances shall not, in and of itself, be deemed a failure to provide or offer reasonable services:
