This is a listed eaves assembly. Listing 8140-2032:0003. This site cites sfm-12-7a-1. Match the model and orientation. A listing is not a permit.

Shakertown documents Dolly Varden as engineered tongue-and-groove cedar paneling in nominal 4- and 6-inch widths with Micro-V or Fine Line edges. Current CAL FIRE OSFM listing 8140-2032:0003 covers horizontal or vertical exterior-wall siding tested to SFM 12-7A-1, while listing 8160-2032:0004 separately covers horizontal soffits tested to SFM 12-7A-3.

Models named on the listing

Model	Application
Dolly Varden Micro-V	tongue-and-groove wall or soffit paneling; match the application-specific OSFM listing
Dolly Varden Fine Line	tongue-and-groove wall or soffit paneling; match the application-specific OSFM listing

The wall and soffit listings are separate. Wall listing 8140-2032:0003 names SFM 12-7A-1 and permits horizontal or vertical installation; soffit listing 8160-2032:0004 names SFM 12-7A-3 and is horizontal-only. Do not transfer a test or orientation between them.
The current OSFM listing names SFM 12-7A-3. Shakertown's current product page separately names ASTM E2957 for direct-to-joist WUI soffits; the two methods are not interchangeable. Obtain the applicable report and verify its specimen and acceptance conditions.
The OSFM soffit listing is horizontal-only and covers specified species, six-ply construction, 11/16-inch true thickness, and 4- through 20-foot lengths. Match the exact panel, edge, framing, fasteners, joints, finish, and installation instructions to the current data sheet.
OSFM listing is not a permit. The authority having jurisdiction decides.

Where this applies

A product is a national record; where it applies is a fact about a place. The rule that binds a given address — and every product matching it — is published on that place's own answer page, linked above and re-linked by the location lens. The complete per-place claim graph for this record, including every open official check, is in its JSON twin.
