Counts are permits issued per calendar month as Kitsap County publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.

Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice. How we calculate approval times.
Housing law — Washington
Washington's HB 1337 (2023) requires cities to allow at least two ADUs per lot in urban growth areas, bans owner-occupancy requirements, and limits parking and impact fees.
HB 1110 (2023) ends single-family-only zoning in larger cities, requiring duplex-to-sixplex middle housing scaled by city size, with Puget Sound cities phasing in compliance from 2025.
