Key provisions · Claude summary of the digest, not bill text

Tightened postentitlement phase permit review by capping plan check cycles, narrowing tolling, shortening appeal timelines, and making violations enforceable under the Housing Accountability Act.

  • Two plan checks. Prohibited a local or state agency from requiring or requesting more than 2 plan check and specification reviews for a building permit application, while allowing denial of noncompliant applications after 2 reviews and allowing applicants to request additional submittals.
  • Inspection deviations. Prohibited agencies from requiring actions, through building inspections, that deviate from a previously approved building plan or similar approval, except as specified.
  • Tolling narrowed. Replaced outside-entity tolling with tolling only when federal or state law requires review by an independent public agency before the agency may act, with notice to the applicant.
  • Faster appeals. Shortened final appeal determinations to 30 business days for projects of 25 units or fewer and 45 business days for projects of 26 units or more, and removed prior appeal-body specifications.
  • Writ of mandate. Authorized applicants to seek a writ of mandate compelling approval if an appeal is denied, not decided on time, or no appeals process is provided.
  • HAA enforcement. Made violations of the postentitlement phase permit provisions a violation of the Housing Accountability Act and included failure to comply with them in the definition of "disapprove the housing development project."
  • Charter cities. Declared the changes a matter of statewide concern applying to all cities, including charter cities; incorporated changes proposed by SB 1072 to Government Code Section 65589.5 if enacted last.

SEC. 1.5In the navigator:§ 65589.5changes

Section 65589.5 of the Government Code is amended to read:

SEC. 2In the navigator:§ 65913.3changes

Section 65913.3 of the Government Code is amended to read:

SEC. 3

The amendments of subclause (I) of clause (i) of subparagraph (A) of paragraph (3) of subdivision (k) of Section 65913.3 of the Government Code made by this act do not constitute a change in, but are declaratory of, existing law.

SEC. 4. The Legislature finds and declares that Section 2 of this act amending Section 65913.3 of the Government Code addresses a matter of statewide concern rather than a municipal affair as that term is used in Section 5 of Article XI of the California Constitution. Therefore, Section 2 of this act applies to all cities, including charter cities.

SEC. 5

Section 1.5 of this bill incorporates amendments to Section 65589.5 of the Government Code proposed by both this bill and Senate Bill 1072. That section of this bill shall only become operative if (1) both bills are enacted and become effective on or before January 1, 2027, (2) each bill amends Section 65589.5 of the Government Code, and (3) this bill is enacted after Senate Bill 1072, in which case Section 1 of this bill shall not become operative.

SEC. 6. No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution because a local agency or school district has the authority to levy service charges, fees, or assessments sufficient to pay for the program or level of service mandated by this act, within the meaning of Section 17556 of the Government Code.
