What OSHPD Is Called Now
California renamed the former Office of Statewide Health Planning and Development (OSHPD) to the Department of Health Care Access and Information (HCAI). In field conversation, “OSHPD” still gets used all the time, but the current official agency name is HCAI.
Official pages: OSHPD becomes HCAI, HCAI Building Safety.
OSHPD / HCAI Occupancy Classifications
| Classification | Facility Type | Description | Jurisdiction Notes |
|---|---|---|---|
| OSHPD 1 | General Acute Care Hospitals | Buildings providing 24-hour inpatient care, including surgery, intensive care, and emergency services. | HCAI has full jurisdiction for plan review, construction observation, and major compliance oversight. |
| OSHPD 1R | Removed from Acute Care | Former hospital buildings that no longer provide acute care services but remain on a hospital campus. | Always verify the exact current use, facility license status, and project path. |
| OSHPD 2 | Skilled Nursing & Intermediate Care | Used for freestanding skilled nursing facilities and related intermediate care uses. | Often divided in practice into 2A and 2B construction types, but HCAI remains central to the compliance framework. |
| OSHPD 3 | Licensed Clinics | Primary care, specialty, and surgical clinic environments. | Jurisdiction is often relinquished to the local building official, while HCAI still sets the standards. |
| OSHPD 4 | Correctional Treatment Centers | Health facilities within law enforcement or correctional institutions. | Verify the exact review and inspection path from the approved project documents. |
| OSHPD 5 | Acute Psychiatric Hospitals | Facilities providing 24-hour inpatient psychiatric care. | Like OSHPD 3, jurisdiction may often stay with the local authority even though HCAI standards still matter. |
Seismic Performance Categories (SPC / NPC)
In healthcare work, “OSHPD levels” also gets used in conversation to describe seismic performance categories. These do not replace occupancy classifications. Instead, they measure how the building and its critical nonstructural systems are expected to perform during and after an earthquake.
| Level | Structural Performance Category (SPC) | Non-Structural Performance Category (NPC) |
|---|---|---|
| 1 | At risk of collapse and must be removed from service. | Non-functional. Systems and equipment do not meet seismic bracing standards. |
| 2 | Does not jeopardize life safety, but may be unrepairable. | Critical systems braced only in high-hazard areas. |
| 3 | Compliant with the 1973 hospital seismic act and likely repairable. | Full compliance for critical life-safety systems, including fire alarms. |
| 4 | High compliance and expected to become operational shortly after a seismic event. | Includes NPC 3 plus cladding and ceiling systems meeting seismic requirements. |
| 5 | Immediate occupancy and full post-event functionality. | Includes NPC 4 plus on-site backup support for extended continued operation. |
Who Issues the Permit for Different OSHPD / HCAI Projects?
For many hospital and healthcare projects, the permit and construction observation path runs through HCAI rather than the local building department. HCAI breaks this into a formal process including project creation, plan review, and permit and construction observation.
When HCAI is typically central
- General acute care hospital building work
- Skilled nursing and intermediate care facility work
- Projects where the HCAI permit path is explicitly required
- Projects with healthcare seismic and observation obligations tied to HCAI programs
When local authority may still matter
- Certain clinic and outpatient work
- Some OSHPD 3 scenarios
- Scope-specific local fire authority coordination
- Deferred submittals and fire department signoff points depending on the project setup
Authority Stack for Healthcare Fire Alarm Design
| Authority Layer | Why It Matters | Typical Relevance to Fire Alarm Work |
|---|---|---|
| HCAI process and guidance | Controls project path, submittals, observation, seismic programs, and healthcare-specific review culture. | Permits, comments, deferred submittals, field observation, TIO, and closeout. |
| California Building Code / Fire Code / Administrative Code | Adopted state law framework. | Occupancy, egress, healthcare construction administration, and inspection path. |
| California Electrical Code | Wiring methods, separation, and healthcare electrical environment. | Raceways, supports, conductor fill, Article 760 issues, and healthcare electrical coordination. |
| NFPA 72 | Fire alarm and signaling design, installation, testing, records, ECS, notification, and pathways. | Chapters 10, 12, 14, 17, 18, 21, 23, 24, and 26 depending on scope. |
| NFPA 99 and project-specific standards | Healthcare facility operational and system context. | System interfaces, essential systems, and clinical environment expectations. |
| Manufacturer listing / HCAI preapprovals | Listed equipment still has to align with California healthcare seismic and installation rules. | OSP, OPM, OPD, anchorage details, support details, and approved methods. |
Does the Fire Alarm Design Need an FPE or EE Stamp?
On healthcare work, the better question is not “Does this always need one exact stamp type?” but “Who is the registered design professional in responsible charge for this exact scope and submittal?”
In practice, fire alarm design responsibility on HCAI work is often carried through the engineer or design professional of record, commonly involving an Electrical Engineer (EE), a Fire Protection Engineer (FPE), or coordinated work under the larger project design team.
Plan and Submittal Requirements for HCAI Fire Alarm Work
HCAI’s standard process requires project creation through the eServices Portal, upload of construction documents, review, comment resolution, permit issuance, construction observation, and closure. The permit page also notes that a Testing, Inspection and Observation (TIO) Program must be submitted before a permit can be issued.
| Document | What It Should Do | Why It Matters on HCAI Work |
|---|---|---|
| Code summary / basis of design | Identify occupancy, project type, governing codes, and facility classification assumptions. | Keeps reviewers from having to guess the project identity. |
| Floor plans with device layout | Show every initiating device, control interface, NAC or speaker coverage area, modules, and major pathway. | Core drawing set for review and field observation. |
| Riser diagram | Show panel architecture, node relationships, power supplies, transponders, amplifiers, pathway classes, and interfaces. | Vital for review, troubleshooting, and acceptance. |
| Sequence of operations matrix | Translate cause and effect into a reviewable control logic format. | Prevents scope gaps between trades. |
| Voltage drop and battery calculations | Demonstrate reliable operation under adopted rules and manufacturer parameters. | Critical for review and acceptance testing. |
| Cut sheets and listings | Show model numbers, listings, compatibility, and key product data. | Essential for review and field verification. |
| Seismic support details | Show cabinet anchorage, bracing, supports, and preapproved details where used. | Healthcare work in California demands real seismic coordination. |
| Deferred submittals if allowed | Identify which items are deferred and who reviews them. | Needs alignment with HCAI office and field expectations. |
| TIO documentation | Define who inspects, tests, observes, and signs what. | Permit prerequisite and closeout backbone. |

Install to Signoff Workflow for the Field
| Phase | What the Fire Alarm Team Should Verify | Typical Failure Mode if Ignored |
|---|---|---|
| Preconstruction | Approved documents, permit status, phasing restrictions, infection control coordination, and outage planning. | Installing from a non-final set and getting hit by comments later. |
| Rough-in | Raceways, supports, wall ratings, above-ceiling conflicts, seismic bracing approach, and pull box access. | Conduit work that clashes with ceilings, med gas, duct, or support rules. |
| Device install | Mounting heights, location intent, room function, ceiling treatment, and patient care sensitivity. | Approved symbol on paper, wrong real-world location in the room. |
| Panel and power | Branch circuit source, breaker identification, clearances, cabinet anchorage, and remote supply layout. | Late-stage power issues and relocation requests. |
| Programming / cause-effect | Matrix confirmation, interface verification, phasing logic, trouble routing, and supervisory mapping. | System “works” in isolation but fails the healthcare sequence intent. |
| Pretest | Point list, labels, addresses, candela and speaker taps, battery, voltage drop assumptions, and record documents. | Acceptance test turns into live improvisation. |
| Final / turnover | As-builts, O&M manuals, test records, owner training, and signoff documents. | System passes but turnover package is incomplete. |
Field Installation Requirements: Wiring, Conduit, Devices, and Placement
Wiring Methods
- Use the adopted California Electrical Code and NFPA 72 pathway requirements as the baseline.
- Coordinate healthcare electrical-space requirements early, especially where branch power and transfer equipment are involved.
- Keep supports, boxes, and raceways coordinated with ceiling systems, ductwork, med gas, plumbing, and seismic support locations.
- Do not let field routing break the pathway intent or future service access.
Device Placement
- Match device location to the actual room function, not just the room name on an old background.
- Patient rooms, staff work areas, corridors, mechanical rooms, and specialty spaces can all change application decisions.
- Coordinate ceiling treatments, soffits, beams, lifts, med gas booms, and infection-control restrictions before finalizing spot locations.
Deferred Submittals
Deferred does not mean casual. It means controlled. Verify what is deferred, who reviews it, and how it gets approved and documented in the field.
OSHPD / HCAI Seismic Bracing for Fire Alarm Conduit and Panels
On California hospital work under HCAI, fire alarm systems and their supporting nonstructural elements are subject to a stricter seismic framework than ordinary commercial projects. In practical terms, that means the fire alarm designer and installer need to think about more than just device layout and pathway routing. The support method, attachment detail, cabinet anchorage, and deferred submittal path all matter.
HCAI separates its seismic preapproval programs by purpose. The OSHPD Preapproval of Manufacturer’s Certification (OPM) is used for the seismic design of supports and attachments for nonstructural components, including electrical raceway bracing. The OSHPD Preapproved Details (OPD) program provides HCAI preapproved standard details. The OSHPD Special Seismic Certification Preapproval (OSP) program applies to nonstructural components that require special seismic certification, such as certain control panels and equipment.
1) Importance Factor and Why Hospital Fire Alarm Work Gets More Stringent
For HCAI hospital projects, nonstructural components tied to life safety and essential building function are generally designed under the more demanding healthcare seismic rules. HCAI OSP documentation for wall-mounted fire alarm control panels shows an Importance Factor (Ip) of 1.5, which is the level typically associated with critical nonstructural hospital components. That is one reason healthcare fire alarm seismic support and anchorage details are reviewed much more closely than standard commercial work.
2) Suspended Above-Ceiling Fire Alarm Conduit
Suspended fire alarm conduit above a hospital ceiling should be treated as part of the building’s nonstructural distribution system and supported from the structure using an approved seismic support approach. The commonly cited California thresholds for exempting some raceway runs from separate seismic bracing are tied to MEP distribution-system interpretation language, including the familiar 12-inch hanger length threshold and the 10 pounds-per-foot trapeze threshold.
These concepts align with the seismic design framework used in the California Building Code (CBC) and ASCE 7 for nonstructural components, which form the structural basis for many HCAI seismic review decisions.
- Independent support: fire alarm raceways should be supported from the structure, not from the ceiling grid or ceiling support wires.
- Short drops: where each hanger in the run does not exceed 12 inches from the raceway support point to the structure, the run may fall within the commonly cited exemption framework used for MEP distribution systems.
- Longer drops: when the drop exceeds that threshold, separate seismic restraint design is generally needed.
- Grouped conduits on trapeze: if multiple conduits are carried on a trapeze and the assembly exceeds the commonly cited 10 lb/ft threshold, the trapeze should be treated as a seismically braced support assembly rather than an ordinary hanger arrangement.
In practice, hospital fire alarm designers usually specify rigid bracing details, strut-framed support assemblies, or approved cable-bracing assemblies where permitted by the approved design. The right answer is not “whatever usually works,” but “whatever matches the approved seismic support detail, the project engineer’s design assumptions, and the HCAI-accepted submittal.”
3) Bracing Direction, Clearance, and Assembly Behavior
Once a raceway support assembly requires seismic restraint, the design should address movement in both principal directions rather than treating the conduit as if it only needs one-direction restraint. On real hospital jobs, that means thinking about transverse and longitudinal restraint, attachment capacity, brace spacing, and coordination with all the other overhead systems competing for the same ceiling space.
- Rigid bracing: often preferred where approved, commonly using steel strut systems that can resist both tension and compression.
- Cable bracing: can be used where permitted, but generally must work in opposing pairs because cable acts in tension rather than compression.
- Separation: brace wires and struts should be laid out so the intended clearance to adjacent unbraced systems is maintained and components do not strike one another during seismic movement.
4) Wall-Mounted Fire Alarm Panels and Conduit
Wall-mounted fire alarm control panels are usually handled differently from suspended raceway. HCAI OSP examples for fire alarm control panels show rigid wall-mounted configurations, and those approvals make clear that the installed mounting configuration must be similar in strength and stiffness to the tested configuration.
Conduits mounted directly to structural walls are often treated very differently from independently suspended runs because the wall itself provides continuous support. Even so, the attachment to the wall or structure still has to match the approved detail, anchor type, and substrate assumptions. If the raceway or cabinet crosses a seismic separation joint or another location where differential movement is expected, the design should address movement explicitly instead of pretending the building will move as one rigid block.
5) Approved Anchors, Preapprovals, and Deferred Submittals
HCAI’s preapproval structure is designed to streamline this work when the design team uses accepted details and accepted manufacturers’ seismic support systems. That is why hospital contractors often rely on OPM assemblies for support and attachment design, and OPD details where applicable, instead of reinventing the bracing package on every job.
- OPM: voluntary HCAI preapproval program for the seismic design of supports and attachments for nonstructural components, including electrical raceway bracing.
- OPD: HCAI preapproved standard architectural and engineering details.
- OSP: voluntary HCAI preapproval program for special seismic certification of nonstructural components that require it.
- Anchors: attachment details should match approved substrate assumptions, manufacturer data, and the specific accepted seismic detail for the project condition.
Fire alarm seismic bracing should be shown on the approved construction documents when it is part of the design package, or submitted through the project’s deferred submittal path when that approach is allowed. HCAI’s Fire and Life Safety FAQ confirms that the field Fire and Life Safety Officer decides what fire alarm deferred submittal documents can be reviewed in the field, using the FREER Manual as a guide.
6) Practical Design Rules for Fire Alarm Teams
- Support fire alarm raceways from the structure using an approved support method and detail path.
- Do not assume all conduit runs are exempt from seismic bracing just because they are small.
- Check hanger length, total trapeze weight, brace direction, and brace clearance early.
- Use OPM / OPD details for raceway support and attachment design where appropriate.
- Use OSP only where the equipment itself requires special seismic certification.
- Match the installed field condition to the approved detail, tested configuration, and substrate assumptions.
- Coordinate seismic joints, flexible fittings, and movement allowances wherever the pathway crosses a separation condition.
- Do not leave seismic bracing to a last-minute means-and-methods conversation if the approved design already controls it.
