Agency fees, funding accounts and manufacturer fee provisions
The Division of the State Architect—Access Compliance may charge manufacturers fees to cover costs for detectable warning products and directional surfaces (authorized in **§ 12-11A.207**), and those fees must be placed into the **Disability Access Account** (**§ 12-11A.208**). The CRSC text authorizes fee collection and prescribes the fund; it does not provide fee amounts, schedules, exemptions, or spending rules — those details come from the Division’s implementing regulations and published fee schedules.
Last reviewed: July 6, 2026
What the code requires — plain English
The Division of the State Architect—Access Compliance may impose a fee on manufacturers of specified detectable warning products and directional surfaces to cover program costs (§ 12-11A.207). Fees received from manufacturers must be deposited in the Disability Access Account (§ 12-11A.208) .
The single most important rule: the Division may charge manufacturers for the costs of evaluating and maintaining detectable-warning/directional-surface approvals, and those collected fees are required to go into the Disability Access Account. § 12-11A.207 and § 12-11A.208 .
Requirements in detail
Who may be charged
- The regulating agency is the Division of the State Architect—Access Compliance (bolded on first mention). That Division may impose a fee on manufacturers of the specified products to cover program costs (§ 12-11A.207) .
Where fees go
- All fees collected from manufacturers are to be placed in the Disability Access Account—this is the required fund destination under § 12-11A.208 .
What the code text does and does not specify
- The CRSC text authorizes fee imposition and requires deposit to a named account, but it does not in the retrieved text specify fee amounts, assessment method, billing frequency, which exact products or models are charged, or how the funds are spent or reported. Those operational details are not present in § 12-11A.207 or § 12-11A.208 as retrieved; you will need to consult the Division’s implementing regulations, fee schedules, or guidance for those specifics .
Decision-relevant dimensions (quick reference)
| Decision dimension | What the CRSC requires or permits | Typical question you need answered | Code Reference |
|---|---|---|---|
| Authority to charge | Division "may impose a fee" on manufacturers | Is the Division authorized to assess manufacturer fees? | § 12-11A.207 |
| Fee deposit destination | Collected fees must go to Disability Access Account | Where must collected fees be deposited? | § 12-11A.208 |
| Fee amount / schedule | Not specified in retrieved text | How much and how often are fees charged? (Not in § 12-11A.207/.208) | (Not specified in §§ 12-11A.207–208) |
| Use of funds | Not specified in retrieved text | What expenditures are allowed from the Account? (Not stated) | (Not specified in §§ 12-11A.207–208) |
| Relation to approvals | Two-year recertification requirement exists elsewhere for these products; fees likely relate to that program | Are fees tied to the two-year product recertification? (Not specified here) | § 12-11A.206 (two-year approval) |
Exceptions & special cases
- The retrieved CRSC text does not list any statutory exemptions (for example, small manufacturers or particular products) from the fee in § 12-11A.207, nor does § 12-11A.208 carve out alternative deposit rules. If exemptions exist they would appear in implementing rules or other statutes; they are not present in the retrieved sections .
- The code distinguishes detectable warning products and directional surfaces and links them to evaluation and recertification rules elsewhere (e.g., independent entity review and two-year approvals), but the fee and account language is limited to authorizing fees and identifying the fund—operational special cases are not described in these sections .
Common mistakes
- Assuming a numeric fee schedule exists in § 12-11A.207. The section authorizes the Division to impose a fee but does not list amounts or rates; don’t rely on the CRSC sections alone for fee figures .
- Treating fees as discretionary to be held in a general fund. Fees collected under § 12-11A.207 must be deposited in the Disability Access Account per § 12-11A.208; do not divert them absent other authority .
- Confusing the two-year product recertification requirement with the fee timing. The CRSC requires a two-year recertification for detectable warning products elsewhere, but § 12-11A.207/.208 do not specify that the fee is charged on that schedule; confirm timing with implementing guidance .
Worked example (illustrative only — numbers not in the CRSC)
- Facts (hypothetical): The Division adopts a supplemental rule that charges $150 per product model per recertification cycle and recertification is every 2 years.
- Calculation (illustrative): Manufacturer A sells 3 approved detectable-warning product models. At recertification time the Division bills Manufacturer A: 3 models × $150 = $450.
- Accounting: The Division receives the $450 and deposits it into the Disability Access Account as required by § 12-11A.208.
- Notes: This example uses illustrative dollar and scheduling values. Neither the $150 amount nor the billing cadence is specified in § 12-11A.207 or § 12-11A.208; you must check the Division’s formal fee schedule or regulations for actual amounts and timing .
Related provisions (CRSC)
- § 12-11A.205 — Independent entity evaluation for detectable warning products/directional surfaces (selection and role) .
- § 12-11A.206 — Two-year approval / recertification requirement for detectable warning products and directional surfaces .
- § 12-11A.209 — Product consistency/uniformity requirements (shape, color fastness, conformation, acoustic quality, resilience, attachment) .
- § 12-11A.210 — Definition of “significant degradation” (at least 90 percent of approved design characteristics) .
- § 12-11A.211 — Selection standards for the independent entity used by the Division .

CBC § 66000 Medium relevance — show source text
Can school districts charge impact fees? Yes. School districts are authorized to, but do not have to, levy impact fees for ADUs larger than 500 square feet pursuant to Section 17620 of the Education Code and the Mitigation Fee Act (Gov. Code, § 66000). ADUs less than 500 square feet are not subject to school impact fees. Local agencies are encouraged to coordinate with school districts to carefully weigh the importance of promoting ADUs and to ensure appropriate nexus studies are conducted on fees to facilitate construction or reconstruction of adequate school facilities, as required by the Mitigation Fee Act. Local agencies should not withhold the issuance of a permit to create an ADU or JADU due to the imposition of school fees.
Can I still be charged water and sewer connection fees? ADUs constructed from existing space and JADUs shall not be considered by a local agency, special district, or water corporation to be a new residential use for purposes of calculating connection fees or capacity charges for utilities, unless constructed concurrently with a new single-family dwelling (Gov. Code, § 66324, subd. (b)). The connection fee or capacity charge shall be proportionate to the burden of the proposed ADU, based on its square footage or plumbing fixtures as compared to the primary dwelling (Gov. Code, § 66324, subd. (e)).
Fire Protection and Fire Sprinkler Requirements
Can fire sprinklers be required for ADUs? Only when sprinklers are required for the existing primary residence. Installation of fire sprinklers shall not be required in attached, detached, or converted ADUs if sprinklers are not required by building codes for the existing primary residence. For example, a detached singlefamily home designed and constructed decades ago would not have been required to have fire sprinklers installed under the applicable building code at the time. However, if the same primary dwelling recently underwent significant alteration and is now required to have fire sprinklers, any ADU created after that alteration must be provided with fire sprinklers. Additionally, the construction of an ADU under this code section shall not trigger a requirement for fire sprinklers for the primary residence. Finally, if a primary dwelling currently does not have fire sprinklers, and an attached ADU is proposed which would trigger fire sprinkler requirements due to the increase in livable space, that requirement shall not be imposed upon the primary dwelling unit. (Gov. Code, §§ 66314, subd. (d)(12); 66323, subd. (d).)
23
Funding
Is there financial assistance or funding available for ADUs? Possibly. While at the time of this writing the funds have been exhausted, the California Housing Finance Agency’s (CalHFA) ADU Grant Program provided up to $40,000 in assistance to reimburse qualifying homeowners for predevelopment costs necessary to build an ADU or JADU on a lot with an owner-occupied single-family dwelling unit. The ADU Grant Program was intended to create more housing units in California by providing a grant to reimburse qualifying homeowners for predevelopment costs. Predevelopment costs include, but are not limited to, architectural designs, permits, soil tests, impact fees, property surveys, and energy reports.
Some local agencies are creating funding opportunities for ADU/JADU predevelopment and construction costs, or they are waiving fees.

PREFACE
This document is Part 12 of thirteen parts of the official triennial compilation and publication of the adoptions, amendments and repeal of administrative regulations to California Code of Regulations, Title 24, also referred to as the California Building Standards Code. This part is known as the California Referenced Standards Code.
The California Building Standards Code is published in its entirety every three years by order of the California legislature, with supplements published in intervening years. The California legislature delegated authority to various state agencies, boards, commissions and departments to create building regulations to implement the State’s statutes. These building regulations, or standards, have the same force of law, and take effect 180 days after their publication unless otherwise stipulated. The Califor- nia Building Standards Code applies to occupancies in the State of California as annotated.
A city, county, or city and county may establish more restrictive building standards reasonably necessary because of local climatic, geological or topographical conditions. Findings of the local condition(s) and the adopted local building standard(s) must generally be filed with the California Building Standards Commission (or other filing if indicated) to become effective, and may not be effective sooner than the effective date of this edition of the California Building Standards Code . Local building standards that were adopted and applicable to previous editions of the California Building Standards Code do not apply to this edition without appropriate adoption and the required filing.
The referenced standards contained in Part 12 are developed by the state agencies listed herein. The Part 12 Cross Reference Table herein identifies the state agency to which the standard applies, the subject of the standard and the provisions in other parts of Title 24 where the application of the standard is required.

CRSC § 317.1.2.1 Medium relevance — show source text
The provisions of Section 317 through 323 also establish minimum standards for earthquake evaluation and design for rehabilitation of existing public buildings currently under the jurisdiction of DSA-SS.
317.1.2.1 Reference to other chapters. For public schools, where reference within this chapter is made to sections in Chapters 16, 17, 18, 19, 21 or 22 of the California Building Code, the provisions in Chapters 16A, 17A, 18A, 19A, 21A and 22A of the California Building Code, respectively, shall apply instead.
317.1.3 Community college buildings. [DSA-SS/CC] The provisions of Sections 317 through 323 establish minimum standards for earthquake evaluation and design for the rehabilitation of existing buildings for use as community college buildings under the jurisdiction of the Division of the State Architect—Structural Safety/Community Colleges [DSA-SS/CC], refer to Section 1.9.2.2.
The provisions of Section 317 through 323 also establish minimum standards for earthquake evaluation and design for rehabilitation of existing community college buildings currently under the jurisdiction of DSA-SS/CC.
317.1.3.1 Reference to other chapters. For community colleges, where reference within this chapter is made to sections in Chapters 17 or 18 of the California Building Code, the provisions in Chapters 17A and 18A of the California Building Code, respectively, shall apply instead.
317.2 Scope. All alterations, structurally connected additions and/or repairs to existing structures or portions thereof shall, at a minimum, be designed and constructed to resist the effects of seismic ground motions as provided in this section. The structural system shall be evaluated by a registered design professional and, if not meeting or exceeding the minimum seismic design performance requirements of this section, shall be retrofitted in compliance with these requirements.
Exception: Those structures for which Section 317.3 determines that assessment is not required, or for which Section 317.4 determines that retrofit is not needed, then only the requirements of Section 317.11 apply.
317.3 Applicability.
317.3.1 Existing state-owned buildings. [BSC, DSA-SS] For existing state-owned structures including all buildings owned by the University of California and the California State University, the requirements of Section 317 apply whenever the structure is to be retrofitted, repaired or modified and any of the following apply: 1. Total construction cost, not including cost of furnishings, fixtures and equipment, or normal maintenance, for the building exceeds 25 percent of the construction cost for the replacement of the existing building. The changes are cumulative for past modifications to the building that occurred after adoption of the 1995 California Building Code and did not require seismic retrofit.

Frequently asked questions
Who sets the dollar amount of the manufacturer fee?
The CRSC authorizes the Division to impose a fee (§ 12-11A.207) but does not state amounts; the Division’s implementing regulations or fee schedule set the dollar amounts .
Where must collected fees be deposited?
All fees collected from manufacturers under this authority must be placed in the Disability Access Account per § 12-11A.208 .
Are fee amounts or exemptions listed in these sections?
No. § 12-11A.207 and § 12-11A.208 do not include fee schedules, exemptions, or procedural billing rules; those details are not present in the retrieved text and must be obtained from the Division’s rules or guidance .
Is the fee tied to the two-year recertification schedule?
The CRSC links detectable-warning products to a two-year recertification elsewhere, but the fee sections do not specify timing; check the Division’s implementing rules to confirm whether fees are charged on recertification or another schedule .
Can local jurisdictions use these fees for other purposes?
Not without separate authority. The CRSC requires deposit to the Disability Access Account; permitted uses would be defined by statute or implementing regulations—not in §§ 12-11A.207–208 as retrieved .
