One Seattle Plan Overview

The One Seattle Plan is Seattle’s updated Comprehensive Plan, which guides how the city will grow and develop through 2044. It addresses housing, land use, transportation, and neighborhood planning across the city.

The plan was adopted by the Seattle City Council in December 2025. It is now the official framework used to guide future zoning decisions and development.

What the Plan Does

The One Seattle Plan establishes a long-term vision for:

• Where housing and jobs will be located
• How neighborhoods may change over time
• How the city plans for population growth
• How land is used across Seattle

It also aligns with state requirements to increase housing capacity and support population growth.

Key Components

Growth Strategy

The plan identifies different types of areas where growth will be focused:

• Urban Centers: Larger areas with significant housing, jobs, and transit access
• Neighborhood Centers: Smaller hubs where additional housing and mixed-use development may be encouraged
• Corridors: Streets and transit routes where increased density may be considered

These designations help guide where future zoning changes may occur.

Housing Changes

Seattle has already implemented citywide zoning updates that allow a broader range of housing types in residential neighborhoods. These include duplexes, triplexes, fourplexes, and, in some cases, up to six units per lot.

These changes are part of statewide requirements and are now in effect.

Implementation Phases

Phase 1 Completed

Phase 1 of the plan has been completed and adopted. This phase established:

• The overall growth strategy
• The locations of Urban Centers, Neighborhood Centers, and corridors
• Policy direction for future zoning updates

Phase 2 In Progress

Phase 2 focuses on the details of zoning and development standards. This includes:

• Building heights
• Density limits
• Design standards
• Specific zoning maps

As of 2026, Phase 2 is under review by the Seattle City Council. Updates and revisions may occur as part of the legislative process.

What This Means for Neighborhoods

Neighborhoods across Seattle, including Madrona, may see changes over time. Changes will reflect adopted city goals for housing, growth, and land use, and the
extent and timing will depend on City Council decisions.

Potential changes may include:

• Additional housing types in residential areas
• Increased density near Neighborhood Centers and transit corridors
• Adjustments to building height and scale in certain locations

The extent and timing of these changes will depend on future City Council decisions and implementation steps.

Ongoing Process

Although the One Seattle Plan has been adopted, work continues on:

• Finalizing zoning regulations
• Updating maps and development standards
• Implementing policies over time

City Council review and public input remain part of the process as additional legislation is considered.
