Building ADUs in Sequim's Unique "Blue Hole" Climate
Sequim, Washington is famously known as the "Blue Hole" of the Olympic Peninsula, receiving only about 16 inches of rainfall per year — far less than the surrounding region.

Whether you're looking to house aging parents, generate rental income, or add long-term property value, working with experienced ADU contractors in Sequim, WA is essential to navigating local building requirements and making the most of this sunny Pacific Northwest gem.
Sequim ADU Regulations and Zoning Requirements
Before breaking ground, homeowners must understand that ADU construction in Sequim is governed by both the City of Sequim and Clallam County regulations, depending on whether the property falls within city limits or the surrounding unincorporated areas. Key rules to be aware of include:
- Lot size requirements: Properties within Sequim city limits typically must meet minimum lot size thresholds before an ADU is permitted.
- ADU size limits: Detached ADUs are generally capped at a maximum square footage, often around 1,000 square feet, though this can vary by zone.
- Owner-occupancy rules: Some zones may require the property owner to occupy either the primary residence or the ADU.
- Setback requirements: ADUs must comply with specific front, rear, and side yard setbacks as defined in Sequim's municipal code.
- Utility connections: Separate water and sewer connections may be required, and Sequim's infrastructure considerations must be factored into project planning.
