What does OSHPD regulate (hospitals, skilled nursing, clinics)?

Q: What label will show OSHPD‑specific amendments in the code text?

OSHPD amendments are identified with the acronyms [OSHPD 1] (for OSHPD 1) and [OSHPD 2] (for OSHPD 2) as noted in the sections. § 106.1.3 , § 106.2.3 .

CALGreen gives OSHPD authority over general acute care and acute psychiatric hospitals (§ 106.1) and over skilled nursing/intermediate care facilities (§ 106.2), with precise carve‑outs for distinct‑part units and single‑story Type V construction; always check those two sections and their administrative standards to determine which Title 24 rules OSHPD enforces.

What the code requires — 2–4 sentences

The Office of Statewide Health Planning and Development (OSHPD) enforces CALGreen provisions that apply to state‑regulated health care facilities. Broadly, general acute care hospitals and acute psychiatric hospitals fall under § 106.1 and OSHPD enforcement, while skilled nursing / intermediate care facilities are scoped under § 106.2; clinics are included among state‑regulated health occupancies called out in CALGreen § 101.3.1, and OSHPD implements the applicable administrative and building standards listed in those sections. § 106.1 , § 106.2 , § 101.3.1 .

The practical rule: identify the occupancy (hospital, skilled nursing, clinic), check whether the space is a distinct part or freestanding unit, then apply the OSHPD scope in § 106.1 or § 106.2 to know which CALGreen/Title 24 administrative and building standards OSHPD enforces.

Requirements in detail

Who/what is in OSHPD jurisdiction (plain language)

General acute care hospitals and acute psychiatric hospitals are within OSHPD jurisdiction per § 106.1.
Skilled nursing facilities and intermediate care facilities are addressed by § 106.2 (OSHPD 2). Distinct‑part skilled nursing units that are separate units or freestanding buildings also fall under § 106.2.
Clinics (licensed by CDPH and outpatient clinical services in freestanding hospital buildings) are recognized as state‑regulated health occupancies in CALGreen § 101.3.1 and are addressed through the OSHPD sections and Title 24 Parts adopted by OSHPD.

Which standards OSHPD enforces

OSHPD enforces the Title 24 administrative standards and the applicable Parts of the California Building Standards Code listed in each OSHPD section. For example, § 106.1.1 lists the applicable administrative standards for OSHPD 1, and § 106.2.1 lists administrative standards for OSHPD 2.

Decision‑relevant dimensions (quick reference table)

Decision dimension	Key value (bolded)	Code Reference
Primary hospital scope	General acute care hospitals; acute psychiatric hospitals	§ 106.1
Exclusion from OSHPD 1 (distinct part)	Distinct part units or distinct part freestanding buildings providing skilled nursing or intermediate care are excluded from § 106.1 hospital scope	§ 106.1
Structural exception for OSHPD 1	Skilled nursing / intermediate care facilities of single‑story, Type V, wood or light steel‑frame construction are excluded from structural regulations under § 106.1	§ 106.1
Skilled nursing / intermediate care scope	Skilled nursing facilities and intermediate care facilities (including distinct part units or freestanding buildings when separate)	§ 106.2
Structural inclusion for OSHPD 2	Single‑story, Type V, wood or light steel‑frame skilled nursing/intermediate care facilities are included under OSHPD 2 for structural regulations	§ 106.2
Applicable administrative standards (example)	Title 24, Part 1: Chapters 6 and 7; Title 24, Part 2: Sections 1.1 and 1.10 (for OSHPD 1)	§ 106.1.1
Identification of OSHPD amendments	Amendments for OSHPD 1 appear with the acronym [OSHPD 1]; for OSHPD 2 amendments appear with [OSHPD 2]	§ 106.1.3, § 106.2.3

How to read the two OSHPD entries together

Use § 106.1 to determine whether a building is a general acute care or acute psychiatric hospital and the special structural carve‑outs that change which OSHPD part applies.
Use § 106.2 when the facility is a skilled nursing or intermediate care building (including distinct part or freestanding units) and to determine whether single‑story Type V construction is treated under OSHPD structural rules.

Exceptions & special cases

Distinct‑part skilled nursing units or freestanding skilled nursing buildings that are part of a hospital license are treated under § 106.2 when they are separate units or freestanding buildings — they are excluded from the general acute care hospital scope in § 106.1. § 106.1 § 106.2
For structural rules only: skilled nursing / intermediate care facilities that are single‑story, Type V, wood or light steel‑frame construction are excluded from OSHPD 1 structural jurisdiction but are explicitly brought under OSHPD 2 structural coverage. § 106.1 § 106.2
Administrative and building standard cross‑references: each OSHPD section points to the specific Title 24 Parts and administrative chapters that OSHPD enforces; consult § 106.1.1 and § 106.2.1 for the exact lists. § 106.1.1 § 106.2.1

Common mistakes

Misclassifying a distinct‑part skilled nursing unit inside a hospital as still being covered by the hospital (OSHPD 1) rules — if it is a separate unit or freestanding skilled nursing/in‑term care unit it falls under § 106.2.
Assuming all structural Type V, single‑story skilled nursing buildings are outside OSHPD jurisdiction — they are excluded from OSHPD 1 structural rules but are covered under OSHPD 2 structural rules per § 106.2.
Overlooking the administrative standards OSHPD enforces (Title 24 Parts) — always check the specific applicable administrative standards listed in § 106.1.1 and § 106.2.1.

Worked example — concrete scenario

Scenario: You are evaluating a proposed project: a 1‑story, Type V wood freestanding skilled nursing facility with a separate license (not a ward inside a hospital).

Step 1 — Identify occupancy: this is a skilled nursing facility → check § 106.2. § 106.2
Step 2 — Distinct / freestanding? It is freestanding → § 106.2 explicitly includes distinct part or freestanding skilled nursing services in its application. § 106.2
Step 3 — Construction type: single‑story, Type V wood — § 106.2 states single‑story Type V skilled nursing facilities are included under OSHPD 2 for structural regulations (i.e., OSHPD has structural authority here). § 106.2
Conclusion: The project is within OSHPD jurisdiction under § 106.2; you must apply the administrative and building standards OSHPD lists for OSHPD 2 projects (see § 106.2.1 and § 106.2.2 for the specific Parts/chapters).

Frequently asked questions

Who enforces the CALGreen rules for hospitals and nursing facilities?

OSHPD enforces the CALGreen provisions that apply to the facility types listed in § 106.1 and § 106.2; the sections also list the Title 24 administrative and building Parts OSHPD is delegated to enforce.

If a hospital has a small freestanding clinic on campus, is that clinic under OSHPD?

Freestanding hospital‑owned clinics can be under OSHPD jurisdiction when they meet the licensure/definition described in the applicable OSHPD/administrative rules; CALGreen identifies clinics among state‑regulated health occupancies in § 101.3.1 and OSHPD‑adopted Parts apply.

Does OSHPD apply to the building’s mechanical and HVAC requirements?

Yes — OSHPD adopts and enforces applicable building standards (Title 24 Parts listed in each OSHPD section). Check § 106.1.2 and § 106.2.2 for the Parts OSHPD applies.

What label will show OSHPD‑specific amendments in the code text?

OSHPD amendments are identified with the acronyms [OSHPD 1] (for OSHPD 1) and [OSHPD 2] (for OSHPD 2) as noted in the sections. § 106.1.3, § 106.2.3.
