LEGISLATIVE COUNSEL'S DIGEST


AB 869, as amended, Wood. Hospitals: seismic safety compliance.
(1) Existing law requires, no later than January 1, 2030, owners of all acute care inpatient hospitals to either demolish, replace, or change to nonacute care use all hospital buildings not in substantial compliance with specified seismic safety standards or to seismically retrofit all acute care inpatient hospital buildings so that they are in substantial compliance with those seismic safety standards. Existing law requires the Department of Health Care Access and Information to issue a written notice upon compliance with those requirements.

The bill would require all rural, district, and distressed acute care hospitals to provide the department with a seismic safety compliance plan by no later than July 1, 2026, that describes how the hospital intends to meet the seismic safety requirements described above.

(2)Existing law establishes the Distressed Hospital Loan Program to provide interest-free cashflow loans to not-for-profit hospitals and public hospitals in significant financial distress or to governmental entities representing a closed hospital, except as otherwise provided, to prevent the closure of, or facilitate the reopening of, those hospitals.

This bill would qualify a general acute care hospital that received a distressed hospital loan for an extension of the seismic safety standards described above until January 1, 2032. If the department determines that the cost of design and construction for compliance with these seismic safety standards will result in a financial hardship for a distressed hospital that may result in hospital closure, and state funds, federal grants, or private funds are not available to assist with the cost of compliance, the bill would authorize the distressed hospital to delay compliance until January 1, 2035. The bill would require the department to confirm a distressed hospital’s lack of ability to comply and that the cost of compliance may result in hospital closure, or would substantially impact the accessibility to health care in communities surrounding the distressed hospital. The bill would authorize the department to implement these provisions through emergency regulations.

This bill would authorize a Distressed Hospital Loan Program recipient, a small hospital, a rural hospital, a critical access hospital, or a health care district hospital, as defined, and except as specified, to seek approval from the Department of Health Care Access and Information for a delay to the January 1, 2030, compliance deadline described above by up to 3 years. The bill would require hospitals seeking a delay to submit a seismic compliance plan, as specified, and, if necessary, a Nonstructural Performance Category-5 evaluation report. The bill would also require the hospital and department to identify least 2 major milestones relating to the seismic compliance plan that will be used as the basis for determining whether a hospital is making adequate progress toward meeting the subject hospital’s seismic compliance deadline. The bill would subject the submitted seismic compliance plans to departmental review for reasonableness and require the hospital seeking the delay to submit any documentation requested by the department to assist its review. The bill would require the department to approve or deny a seismic compliance plan and any delay to the seismic compliance deadline within 120 days. The bill would also authorize the department to additionally delay the deadline for compliance by 2 years, up to a maximum of January 1, 2035, as necessary, for hospitals that continue to experience financial distress or that need to deal with contractor, labor, or material delays, acts of God, governmental entitlements, or other circumstances beyond the hospital’s control. The bill would require hospitals eligible to delay compliance under these provisions to comply with the seismic safety standards described above by no later than January 1, 2035.
The bill would impose a fine of $5,000 per calendar day for a hospital’s failure to comply with a revised construction schedule or to meet any major milestone established by the department until the requirements or milestones, respectively, are met. The bill would also prohibit these hospitals from being issued a building permit for any building in the facility except those required for seismic compliance, maintenance, and emergency repairs until the milestone is met and the hospital is adequately progressing toward meeting the subject hospitals seismic compliance, as determined by the department. The bill would require the department to implement the above-described provisions by regulation, as specified.
The bill would require the department to support a hospital requesting a delay under the above-described provisions to explore the opportunities under the Small and Rural Hospital Relief Program to assist with seismic compliance and to annually post a list of hospitals that have been granted a delay on its internet website, as specified.

(3)

(2) Existing law establishes the Small and Rural Hospital Relief Program for the purpose of funding seismic safety compliance with respect to small hospitals, rural hospitals, and critical access hospitals in the state. Existing law requires the department to provide grants to small, rural, and critical access hospital applicants that meet certain criteria, including that seismic safety compliance, as defined, imposes a financial burden on the applicant that may result in hospital closure. Existing law also creates the Small and Rural Hospital Relief Fund and continuously appropriates the moneys in the fund for purposes of administering and funding the grant program.
This bill would require the department to expand eligibility for grants for single- and 2-story general acute care hospitals located in remote or rural areas with less fewer than 80 general acute care beds and general acute care hospital revenue of $75 million or less. The bill would require grants under the program to provide general acute care hospitals with funds to secure an SPC-4D assessment for purposes of planning for, and estimating the costs of, compliance with certain seismic safety standards, as specified. The bill would authorize specified general acute care hospitals to apply for a grant for purposes of complying with those seismic safety standards.

The bill would delay the requirement to meet those and other building standards for specified general acute care hospitals until January 1, 2035, and would exempt a general acute care hospital with an SPC-4D assessment and with a certain estimated cost from those seismic safety standards if the department determines that the cost of design and construction for compliance results in a financial hardship for the hospital and certain funds are not available to assist with the cost of compliance.

(4)Existing law provides for the formation and administration of health care districts.

The bill would also authorize a health care district that meets certain criteria to submit financial information to the department, on a form required by the department, to allow the department to determine if the health care district is financially distressed and if so, would allow the health care district to apply for a grant for the purpose of meeting those seismic safety standards. The bill would delay the requirement to meet the seismic safety standards until January 1, 2032, for a health care district that qualifies for those grants. The bill would exempt a health care district hospital from those requirements until January 1, 2035, if the department determines that the cost of design and construction for compliance with those requirements results in a financial hardship that may result in hospital closure. The bill would authorize the department to implement these provisions through emergency regulations.

If state funds are appropriated to the Small and Rural Hospital Relief Fund in the future for the purpose of complying with the seismic safety standards described in paragraph (1), the bill would require a hospital that qualifies for assessment grants under the program to submit specified financial information relating to, among other things, the accuracy of the hospital’s SPC-4D cost estimates to the department before being awarded state funds.
