The short answer
In California, K-12 school and community college construction is reviewed, permitted and inspected by the Division of the State Architect rather than the local building department, and general acute care hospital, acute psychiatric hospital and skilled nursing buildings are handled by the Department of Health Care Access and Information. On those projects low voltage work is part of the approved construction documents: deferred items cannot be installed before the agency approves them, a field change that affects structural safety, fire and life safety or accessibility must be approved before the affected work proceeds, and an inspector of record retained by the owner provides continuous inspection. The project is certified only after verified reports are filed by the design professionals, the inspector of record and each contractor holding a prime contract.

What triggers DSA review on a school project?#
The Division of the State Architect reviews, approves and provides construction oversight for K-12 public school and community college construction in California. It is not an extra layer on top of the city building department. It replaces it. There is no city plan check, no city inspector, and no city certificate of occupancy on the school building.
DSA reviews in three disciplines: structural safety, fire and life safety, and access compliance. A submitted set is routed to specialists in each, and each set of comments has to be cleared before the project is approved. For a low voltage subcontractor, that matters because a device that seems purely functional can be caught by two of the three. A card reader height, a call station mounting height, an assistive listening system and a visual notification appliance are access compliance items. A cable penetration through a rated corridor wall is fire and life safety. A ceiling mounted speaker or camera and a floor mounted rack are structural safety.
DSA publishes Interpretation of Regulations A-22, which lists construction projects and items exempt from DSA review. The exemptions are specific, not categorical, and IR A-22 states plainly that all public school construction projects, including those exempt from DSA review, approval and construction oversight, must still comply with the currently effective Title 24. Exempt does not mean uncoded.
What triggers HCAI review on a healthcare project?#
The Department of Health Care Access and Information, formerly OSHPD, holds jurisdiction over hospital construction under the Alfred E. Alquist Hospital Facilities Seismic Safety Act. HCAI classifies buildings, and the classification decides who permits the work.
| Classification | Building type | Permitted by |
|---|---|---|
| OSHPD 1 | General acute care hospital buildings | HCAI |
| OSHPD 1R | Hospital buildings removed from acute care service | HCAI |
| OSHPD 2 | Skilled nursing and intermediate care facility buildings | HCAI |
| OSHPD 3 | Licensed clinics and freestanding buildings under a hospital license providing outpatient services | Local building department |
| OSHPD 4 | Correctional treatment centers operated by law enforcement | Certified to HCAI by the operating entity |
| OSHPD 5 | Acute psychiatric hospital buildings | HCAI |
The OSHPD 3 line is where most bid confusion lives. An outpatient clinic, an imaging suite in a medical office building and a physical therapy tenant improvement generally go to the local building department. A clinic licensed under an acute care hospital that serves more than 25 percent inpatients does not. A skilled nursing building is HCAI even when the work is a nurse call replacement rather than a structural project. Confirm the classification with the owner before you price, because it changes the submittal path, the inspection regime and the closeout package. Our healthcare and clinics page and senior living page describe how we sequence this work in occupied facilities.
How DSA, HCAI and a city building department compare#
| DSA | HCAI | Local building department | |
|---|---|---|---|
| Applies to | K-12 and community college construction | OSHPD 1, 1R, 2 and 5 buildings | Everything else, including OSHPD 3 clinics |
| Plan review | Structural safety, fire and life safety, access compliance | Structural, fire and life safety, and health facility code review | Building, electrical, mechanical, plumbing, fire |
| Field inspection | Project inspector certified by DSA, retained by the district | Inspector of record approved by HCAI, employed by the facility | Department inspector, called for by the contractor |
| Inspection frequency | Continuous, by an inspector assigned to the project | Continuous, with field logs reviewed by HCAI staff | Milestone inspections on request |
| Field change to approved work | Category A construction change document on form DSA 140, approved before the affected work begins | Amended construction document by the design professional of record, approved before affected work proceeds | Field correction, often resolved with the inspector on site |
| Deferred items | Approved separately before installation | Approved separately before installation; specifications must prohibit starting work first | Deferred submittal, handled locally |
| Closeout | Verified reports from design professionals, project inspector and prime contractors; project certified or closed without certification | Close-out documentation, then a certificate of occupancy or construction final | Final inspection, then a certificate of occupancy |
The single largest difference for a subcontractor is the middle row. On a private tenant improvement, a field conflict between a cable tray and a duct is solved on site in an hour. On a DSA or HCAI project, if the fix touches the reviewed disciplines, it is a document that goes back to the agency and comes back approved before the work proceeds. Budget the coordination time up front.
Which low voltage systems are inside the reviewed set?#
There is no low voltage exemption. When a project requires DSA or HCAI review, the low voltage drawings are part of the approved construction documents like any other sheet, and the installation has to match them.
DSA’s IR A-22 lists fire alarm and emergency voice alarm communication systems as exempt from structural safety and access compliance review, but expressly not exempt from fire and life safety review, and it exempts reconstruction or alteration of existing fire alarm and emergency voice alarm systems below a cost threshold from DSA review. It does not carry a general exemption for communications, data cabling, intercom, public address, master clock, video surveillance or access control systems. Practically, that means those systems come along with the project.
The items that most often generate agency comments on a low voltage scope are consistent across both agencies:
- Seismic anchorage and bracing of equipment racks, freestanding cabinets, wall mounted enclosures, cable tray and ceiling mounted devices. On HCAI projects anchorage and bracing is a recognized deferred approval category, and the calculations come from an engineer, not from a rack manufacturer’s brochure.
- Penetrations of rated walls, floors, shafts and corridors, and the listed firestop system used at each condition.
- Mounting heights and reach ranges for card readers, call stations, intercom stations, assistive listening receivers and any operable part, which are access compliance items.
- Pathway routing through rated assemblies, smoke barriers and areas of refuge.
- Nurse call and emergency call coverage, station types and annunciation, which on an HCAI project is reviewed against health facility code requirements rather than against a manufacturer’s standard layout. Our nurse call systems page covers the design side.
- Any interface with the fire alarm system. Fire alarm sits outside the C-7 classification and is performed by a licensed C-10 fire alarm contractor. Telelink coordinates the interface and does not perform fire alarm work.
What is a deferred approval and what does it cost you?#
A deferred approval covers a portion of the construction that cannot be fully detailed on the initial approved plans because product design and manufacture vary. HCAI’s design guidance describes it that way and gives medical gas systems, elevators and fire sprinklers as examples. The detailed design is prepared after the main approval, stamped and signed by a California licensed engineer, and submitted for its own agency review.
Two rules make this a schedule item rather than a paperwork item. First, the contractor cannot start construction work on a deferred item before the agency approves it, and HCAI guidance directs that the specifications say so. Second, HCAI expects deferred design documents to be submitted within 30 days of construction start. If a system in your scope is a deferred approval, the design has to be engineered at the beginning of the job, not when the material lands.
For low voltage scopes the deferred item is most often the seismic anchorage and bracing package, and sometimes a manufacturer engineered system whose final layout depends on the equipment selected. Ask at the preconstruction meeting which items are deferred, who is preparing them, and what the agency review duration has been running. Then put the review on the schedule as a lead time.
The project inspector, the inspector of record, and what changes for a sub#
On both DSA and HCAI projects, an inspector works on the project continuously and is not employed by the agency and not employed by the contractor.
On DSA projects the project inspector is certified by DSA in classes based on building size and construction type, and is retained by the school district or community college that owns the project. DSA does not employ project inspectors. The inspector verifies that construction complies with the DSA approved construction documents and files a verified report at the end.
On HCAI projects the inspector of record is employed by the facility, works under the direction of the design professional of record, is approved by HCAI, and must have a current workload report approved by the regional compliance officer before the building permit is issued. The inspector provides continuous inspection, documents discrepancies between the approved plans and the field, and keeps a field log that HCAI staff review. Where a modification is not material, HCAI field personnel confirm acceptability by reviewing that log.
What this changes for a subcontractor is the rhythm of the work. Concealment happens on the inspector’s schedule, not on the crew’s. Cable above a ceiling gets looked at before the grid closes. Anchorage gets looked at before the rack is loaded. Firestop gets looked at before the wall is patched. Crews used to private work often lose a day recalling an inspector to open something back up. The fix is scheduling rather than speed: build the inspection holds into the two week look ahead and treat them as fixed dates rather than as interruptions.
What documentation closes the project out?#
DSA certification is a document exercise, and a project that is built correctly can still fail to certify if the paperwork is short.
| Party | DSA closeout document | Notes |
|---|---|---|
| Architect or engineer in general responsible charge, and the structural, mechanical and electrical engineers | Verified report, DSA 6-AE | One from each design professional in responsible charge |
| Project inspector | Verified report, DSA 6-PI | States that the work complies with the DSA approved construction documents except as noted |
| Each contractor holding a prime contract with the district | Verified report on the DSA 6 series | A construction manager files only if it holds the contracts and is at risk |
| Testing laboratory | DSA 291 | Materials testing |
| Special inspectors | DSA 292 | Where special inspection was required |
| Geotechnical engineer | DSA 293 | Where applicable |
A project that satisfies DSA is certified. A project with missing documents, unresolved deviations or safety deficiencies is closed without certification, which is a problem the district carries on its facilities record and often has to resolve before the next bond project on the same site.
On HCAI projects, close-out documentation is submitted after construction and, once approved, HCAI issues a certificate of occupancy or a construction final and the project is closed in compliance. The owner then applies to the licensing department for the license to operate the facility. That last step is why a hospital or skilled nursing closeout package is not something to hand over in pieces: the owner cannot license the space until the agency is satisfied.
A low voltage subcontractor is rarely the party filing a verified report, because it is rarely a prime contract holder. What it owns is the input: approved submittals matching what was installed, test and certification results, labeled as-builts, firestop documentation with the listed system numbers used, anchorage calculations and their inspection sign-offs, and closeout manuals. Deliver that as a single indexed package. Our for general contractors page lists the format we use.
