CRSC · California Referenced Standards Code
What is the recertification period for detectable warning products and directional surfaces?
If your home or project uses DSA‑approved detectable warnings or directional surfaces, know that the California Referenced Standards Code requires those products to be recertified every two years (no waivers). An independent testing entity chosen by the State evaluates and recertifies products; fees may apply and the products are expected to remain largely unchanged for five years.
Last reviewed: July 6, 2026
What the code requires
Detectable warning products and directional surfaces must be recertified every two years — no exceptions or waivers — as set by § 12-11A.206 and § 12-11B.206.
Detectable warning products and directional surfaces require a mandatory two‑year recertification cycle; the code does not allow an exception or waiver.
Requirements in detail
Recertification interval (short answer)
- The required interval is two years. This is a strict period: every two years without exception or waiver under § 12-11A.206 and § 12-11B.206.
Who performs evaluation / recertification
- 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). The independent entity is a not-for-profit product safety testing and certification organization.
Fees and administrative handling
- The Division of the State Architect — Access Compliance may impose a fee on manufacturers to cover recertification costs (see § 12-11A.207 / § 12-11B.207). Fees collected are placed in the Disability Access Account (see § 12-11A.208 / § 12-11B.208).
Durability & performance expectations (related, but not the recertification interval)
- The code requires that detectable warning products and directional surfaces ensure consistency and uniformity of shape, color fastness, conformation, sound-on-cane acoustic quality, resilience, and attachment will not degrade significantly for at least five years (see § 12-11A.209 / § 12-11B.209). Significant degradation is defined as maintaining at least 90 percent of approved design characteristics (see § 12-11A.210 / § 12-11B.210).
Quick reference table
| Decision dimension | Required value / rule | Code Reference |
|---|---|---|
| Recertification interval | Every 2 years (no exceptions or waivers) | § 12-11A.206, § 12-11B.206 |
| Evaluation entity | Evaluation/recertification by an independent entity selected by DSA‑AC | § 12-11A.205, § 12-11B.205 |
| Manufacturer fee | Division may impose a fee on manufacturers | § 12-11A.207, § 12-11B.207 |
| Fee deposit | Fees go to the Disability Access Account | § 12-11A.208, § 12-11B.208 |
| Durability expectation | No significant degradation for at least 5 years | § 12-11A.209, § 12-11B.209 |
| Significant degradation definition | Maintain ≥ 90% of approved design characteristics | § 12-11A.210, § 12-11B.210 |
Exceptions & special cases
- There are no exceptions or waivers to the two‑year recertification requirement — the code language is explicit: every two years without exception or waiver (see § 12-11A.206 / § 12-11B.206).
- For product evaluation of items used in residential housing, the independent‑entity evaluation is done in consultation with the Department of Housing and Community Development (see § 12-11A.205 / § 12-11B.205).
- The two‑year requirement applies to detectable warning products and directional surfaces installed after January 1, 2001 (see the product approval scope and independent entity language in related sections).
Common mistakes
- Mistake: treating the five‑year durability target as the recertification interval. Correction: recertification is two years; the five‑year statement in § 12-11A.209 / § 12-11B.209 describes expected product longevity, not the approval interval.
- Mistake: assuming recertification may be delayed or waived. Correction: no waivers or exceptions for the two‑year recertification (see § 12-11A.206 / § 12-11B.206).
- Mistake: using non‑approved products. Correction: only approved DSA‑AC detectable warning products and directional surfaces are allowed; manufacturers must participate in the approval/recertification process. See the product approval and independent entity sections.
Worked example
A manufacturer’s detectable warning product is approved and the certificate date is March 1, 2024. Under § 12-11A.206 / § 12-11B.206, the manufacturer must obtain recertification by March 1, 2026 (two years later). If the Division charges a fee, the manufacturer must pay it as part of the recertification process (see § 12-11A.207 / § 12-11B.207). Independently, the product is expected to maintain at least 90% of its approved design characteristics for at least five years per § 12-11A.209 and § 12-11A.210; however, that five‑year durability requirement does not lengthen the mandatory two‑year recertification cycle.

12-3 RELEASING SYSTEMS FOR SECURITY BARS IN DWELLINGS
(This standard includes provisions of Underwriters Laboratories Subject 2326, Appendix B, dated December 17, 1999, reprinted with their permission.)
INTRODUCTION
SECTION 12-3-1—SCOPE
12-3-1.1 These requirements cover releasing systems for bars, grilles, mesh, glazing or other items intended to provide security at doors and windows required for emergency escape from dwelling units. When actuated by the occupant, the system allows the obstructions over the door or window to be moved so occupants can escape in the event of an emergency.

SECTION 11B- 705 — DETECTABLE WARNINGS AND DETECTABLE DIRECTIONAL TEXTURE
11B-705.1 Detectable warnings
11B-705.1.1 General. Detectable warnings shall consist of a surface of truncated domes and shall comply with Section 11B- 705 .
11B-705.1.1.1 Dome size. Truncated domes in a detectable warning surface shall have a base diameter of 0.9 inch (22.9 mm) minimum and 0.92 inch (23.4 mm) maximum, a top diameter of 0.45 inch (11.4 mm) minimum and 0.47 inch (11.9 mm) maximum, and a height of 0.2 inch (5.1 mm).
11B-705.1.1.2 Dome spacing. Truncated domes in a detectable warning surface shall have a center-to-center spacing of 2.3 inches (58 mm) minimum and 2.4 inches (61 mm) maximum, and a base-to-base spacing of 0.65 inch ( 16.5 mm) minimum, measured between the most adjacent domes on a square grid.
Frequently asked questions
How often must a detectable warning product be recertified?
Every two years — without exception or waiver — per § 12-11A.206 and § 12-11B.206.
Who performs the recertification?
An independent entity (a not-for-profit testing/certification organization) selected by the Division of the State Architect — Access Compliance performs evaluations and recertifications (see § 12-11A.205 / § 12-11B.205).
Can a manufacturer skip or delay recertification if the product is durable for five years?
No. The two‑year recertification requirement is mandatory and is separate from the product’s five‑year durability expectation in § 12-11A.209 / § 12-11B.209.
May the Division charge a fee for recertification?
Yes — the Division may impose a fee on manufacturers to cover costs (see § 12-11A.207 / § 12-11B.207), and fees are deposited to the Disability Access Account (see § 12-11A.208 / § 12-11B.208).
What does “significant degradation” mean?
“Significant degradation” means the product retains at least 90 percent of its approved design characteristics (see § 12-11A.210 / § 12-11B.210).
