CRSC · California Referenced Standards Code

What requirements apply to directional surfaces under 12‑11A/12‑11B?

The CRSC (through **§ 12‑11A.204 / § 12‑11B.204**) directs that directional surfaces must meet the California Building Code (Title 24) technical rules; additionally, the CRSC requires independent evaluation of products, two‑year recertification, and that products maintain specified uniformity and durability standards (including a 90% non‑degradation threshold).

What the code requires — plain English

Directional surfaces installed in California are regulated by the California Referenced Standards Code (CRSC). The CRSC states that directional surfaces must comply with the California Code of Regulations, Title 24 — in other words the detailed technical and dimensional requirements are prescribed in Title 24, and the CRSC overlays product‑approval and evaluation rules. See § 12‑11A.204 and § 12‑11B.204 for the controlling CRSC directive.

Directional surfaces are governed by Title 24 (the California building/accessibility rules); the CRSC requires product approval, independent evaluation, and periodic recertification of those products.

Requirements in detail

1) Primary rule in CRSC

  • The CRSC rule is simple and prescriptive: § 12‑11A.204 / § 12‑11B.204 require that directional surfaces must comply with CCR, Title 24. This means installation, dimensions, color, and detectable‑texture performance are enforced through Title 24 provisions rather than repeated in the CRSC.

2) Product approval, testing and ongoing certification (CRSC requirements)

Although the technical dimensions live in Title 24, the CRSC adds mandatory product approval and oversight rules that apply to detectable warnings and directional surfaces:

  • Independent evaluation required — Directional surfaces (and detectable warning products) installed after January 1, 2001 must be evaluated by an independent entity selected by the Division of the State Architect‑Access Compliance (DSA‑AC). See § 12‑11A.205 / § 12‑11B.205.
  • Two‑year recertification — Approved products must be recertified every two years without exception. See § 12‑11A.206 / § 12‑11B.206.
  • Fees and account — The DSA‑AC may impose a fee on manufacturers for evaluation/approval; collected fees are placed in the Disability Access Account. See § 12‑11A.207, § 12‑11A.208 (and the 11B equivalents).
  • Selection of independent entity — The independent entity must be a recognized not‑for‑profit product testing/certification organization with expertise in Title 24 compliance. See § 12‑11A.211 / § 12‑11B.211.

3) Product performance / durability expectations (CRSC requirements)

The CRSC lists attributes that approved products and directional surfaces must demonstrate and preserve:

  • Products must ensure consistency and uniformity in: shape, color fastness, conformation, sound‑on‑cane acoustic quality, resilience, and attachment. See § 12‑11A.209 / § 12‑11B.209.
  • Significant degradation is defined as the product maintaining at least 90 percent of its approved design characteristics; that is the CRSC metric for unacceptable deterioration. See § 12‑11A.210 / § 12‑11B.210.

4) Where to find the dimensional and tactile specifications

  • The CRSC directs you to Title 24. The technical/tactile dimensions for directional textures (for example, transit platform directional texture) are in Title 24 (See CBC / Title 24 accessibility sections such as § 11B‑705.2 and related provisions). The CRSC itself does not restate those dimensions but requires compliance with them via § 12‑11A.204 / § 12‑11B.204.

Quick reference table — decision‑relevant values (from Title 24 / referenced)

Requirement / dimension Value (decision‑relevant) Code Reference
Directional surface must comply with Title 24 — § 12‑11A.204 / § 12‑11B.204
Independent evaluation required (who selects) DSA‑AC selects independent entity § 12‑11A.205 / § 12‑11B.205
Recertification interval Every 2 years § 12‑11A.206 / § 12‑11B.206
Product uniformity attributes required Shape, color fastness, conformation, sound‑on‑cane, resilience, attachment § 12‑11A.209 / § 12‑11B.209
Significant degradation threshold Product must maintain ≥ 90% of approved characteristics § 12‑11A.210 / § 12‑11B.210
Example dimensional specs (Title 24 authority) Directional texture height 0.1 in (2.5 mm) tapering to 0.04 in (1.0 mm); raised bars 0.2 in (5.1 mm) from surface; bar width 1.3 in (33 mm); center‑to‑center 3 in (76 mm); depth ≥ 36 in (914 mm) for platform use — see Title 24 § 11B‑705.2.

Note: the technical numbers in the final row above come from the California Building Code (Title 24) accessibility provisions — the CRSC requires compliance with Title 24 via § 12‑11A.204 / § 12‑11B.204, but the CRSC text itself does not list those numeric values.

Exceptions & special cases

  • Residential products: for directional surfaces used in residential housing, the CRSC requires that the independent evaluation be done in consultation with the Department of Housing and Community Development. See the CRSC scope text.
  • CRSC does not replace Title 24: whenever CRSC is silent on a technical detail (for example, exact bar spacing or color), the applicable Title 24 section governs — follow the Title 24 citation required by § 12‑11A.204 / § 12‑11B.204.

Common mistakes

  • Assuming the CRSC lists the technical tactile dimensions. It does not — it requires compliance with Title 24 and focuses on product approval and certification. The exact tactile/dimensional specs are in Title 24 (e.g., § 11B‑705.2).
  • Installing products that lack a current independent‑entity approval or whose two‑year recertification has lapsed. The CRSC requires evaluation and strict two‑year recertification. See § 12‑11A.205 / § 12‑11A.206 (and 11B equivalents).
  • Using a product that has degraded below the CRSC’s 90% performance threshold without reapproval or replacement — that condition is explicitly defined as significant degradation and is not acceptable. See § 12‑11A.210 / § 12‑11B.210.

Worked example

Scenario: A transit agency plans to install a directional tactile strip directly behind the vehicle doors on a new light‑rail platform.

  • Step 1 — Follow CRSC product approval flow: procure a directional surface product that has been evaluated and approved by the independent entity selected by DSA‑AC (per § 12‑11B.205).
  • Step 2 — Verify Title 24 dimensions: confirm the product meets Title 24 tactile dimensions for transit directional texture: height 0.1 in (2.5 mm) tapering to 0.04 in (1.0 mm); raised bars 0.2 in (5.1 mm) from the surface; bar width 1.3 in (33 mm); center‑to‑center 3 in (76 mm); and depth ≥ 36 in (914 mm) in the direction of travel (these are Title 24 specifications under § 11B‑705.2).
  • Step 3 — Documentation and schedule: obtain the independent‑entity report and keep the product’s recertification schedule on file; plan to recertify every 2 years per § 12‑11B.206.
  • Step 4 — Maintenance: monitor the installed units for significant degradation; if a unit loses more than 10% of its approved characteristics (i.e., drops below 90%), initiate corrective action/replacement. See § 12‑11B.210.

Related provisions (CRSC / Title 24 cross‑references)

  • § 12‑11A.204 / § 12‑11B.204 — Directional surfaces must comply with CCR, Title 24.
  • § 12‑11A.205 / § 12‑11B.205 — Independent entity evaluation requirement.
  • § 12‑11A.206 / § 12‑11B.206 — Two‑year recertification.
  • § 12‑11A.207 / § 12‑11B.207 — Fees for manufacturers.
  • § 12‑11A.209 / § 12‑11B.209 — Required product consistency/uniformity attributes.
  • § 12‑11A.210 / § 12‑11B.210 — Definition and threshold for significant degradation (≥ 90%).
  • Title 24 (California Building Code) accessibility provisions for technical/tactile specifics (example): § 11B‑705.2 (directional texture dimensions for transit platforms).

If you want, I can extract the exact Title 24 text for the specific installation type you’re dealing with (transit platform, boarding area, blended transition, etc.) and map the CRSC product‑approval checkpoints you need to document for plan review.

Frequently asked questions

What exactly does § 12‑11A.204 / § 12‑11B.204 require?

They require that directional surfaces comply with CCR, Title 24 — the CRSC does not restate Title 24 technical specs but mandates compliance and ties products to CRSC product‑approval procedures.

Who performs the required product evaluation?

An independent entity (a not‑for‑profit product testing/certification organization) selected by the Division of the State Architect‑Access Compliance. See § 12‑11A.205 / § 12‑11B.205.

How often must directional surface products be recertified?

Every two years, per § 12‑11A.206 / § 12‑11B.206.

What is “significant degradation” under the CRSC?

“Significant degradation” means the product no longer maintains at least 90 percent of its approved design characteristics — a CRSC threshold for unacceptable deterioration. See § 12‑11A.210 / § 12‑11B.210.

Where do I find the numeric dimensions (height, spacing, depth)?

Numeric tactile/directional dimensions are in Title 24 (California Building Code) accessibility sections — for example § 11B‑705.2 contains directional texture dimensions for transit platforms. The CRSC points you to Title 24 via § 12‑11A.204 / § 12‑11B.204.
