  • Design wind speed: 97 mph (Island County (unincorporated Whidbey and Camano Islands)). Siding and trim are nailed to the maker's schedule for the wind speed, which sets the nail size and spacing.
  • Energy code climate zone 4C: any continuous insulation on the outside of the walls moves the siding out, which changes nail length, trim widths and window and door extensions.

Sources: Island County (unincorporated Whidbey and Camano Islands): Island County. Read 2026-09-28. Climate zones: Washington State Energy Code, Table R301.1. Every number is as the jurisdiction publishes it (its design criteria for houses, IRC Table R301.2(1)); a dash means it isn't published. Your lot can differ with elevation and exposure, so confirm it with the building department before you order.
