Entitlement and Permitting

The entitlement and permitting process is one of the most critical phases of real estate development. After feasibility studies, environmental review, and geotechnical investigations are complete, projects move into securing the approvals needed to begin construction.

In Seattle, this process can take anywhere from 6–24 months depending on project complexity, environmental conditions, and City review timelines. Successful projects require close coordination between development, architecture, engineering, and public agencies from the earliest stages.

At Stack, we help guide projects through this process from early planning through permit approval and construction readiness.

Project Ownership Structure

One of the first major decisions is determining the project ownership structure, which impacts utilities, subdivision strategy, financing, and long-term operations.

Common structures include:

• Fee Simple Townhomes – Individual ownership with separate utility meters.

• Condominiums – Shared ownership with common amenities and potential master utility metering.

• Unit Lot Subdivisions – Common for Seattle townhome projects and often subject to extended City review timelines.

Establishing the right ownership structure early can help avoid delays later in the entitlement process.

Master Use Permit (MUP)

The Master Use Permit (MUP) is Seattle’s primary land use entitlement process and is required before building permits can be issued for many projects.

MUP applications may involve:

• Environmentally Critical Areas (ECA)

• Subdivisions and plats

• Shoreline review

• Rezones

• SEPA review

• Variances

The process typically begins with a preliminary application submitted through the Seattle Services Portal. After an initial City review and site visit, the project team receives guidance on required studies, design review, and next steps.

Projects near shorelines or environmentally critical areas may require additional exemptions or relief applications before moving forward.

Once submitted, projects often go through public notice and comment periods before approval. Approved land use permits generally remain valid for three years.

Building Permit Process

After land use approvals are underway, the project moves into the building permit phase, which focuses on technical and construction review.

Prior to application, teams typically evaluate:

• Zoning and setback requirements

• Height and FAR limits

• Stormwater requirements

• Parking standards

• Applicable development incentives

The architecture team typically leads permit coordination alongside structural, civil, MEP, and utility consultants. Once submitted, projects move through multiple review cycles with City departments including SDCI, SDOT, Seattle Public Utilities, Seattle City Light, and the Fire Department. Efficient responses to correction comments are critical to maintaining schedule.

After all reviews are completed and fees are paid, the permit is issued and construction can begin.

Additional Permits

Many projects also require supplemental approvals, including:

• Street Improvement Permits (SIP) for sidewalk, utility, or right-of-way improvements

• Demolition Permits for existing structures

• Environmentally Critical Area (ECA) Relief for steep slopes, wetlands, or sensitive sites

These additional permits can significantly affect project timelines and should be evaluated early during due diligence.

Coordination Drives Success

The entitlement and permitting process is ultimately a coordination effort between developers, architects, engineers, consultants, agencies, and community stakeholders. As Seattle’s development environment continues to evolve, proactive planning and early coordination are essential to minimizing delays and moving projects efficiently from concept to construction.

At Stack, we work alongside clients and consultants to navigate Seattle’s permitting process from feasibility through construction execution.
