Seattle Pre-Application Conference: When to Use It and What to Expect

The City of Seattle’s pre-application conference (pre-app) is one of the most underused tools available to homeowners and developers planning complex projects. A pre-app gives you direct access to city reviewers — planners, engineers, and fire marshal staff — before you submit a building permit application. For the right projects, it can prevent months of delays and save tens of thousands of dollars.

This guide explains when a pre-application conference is worth pursuing, what it involves, and how to use it effectively.

What Is a Pre-Application Conference?

A pre-application conference is a meeting with City of Seattle SDCI (Department of Construction and Inspections) staff to discuss a proposed project before permit application. You bring your preliminary design and specific questions; city staff from relevant departments review your materials in advance and attend the meeting to provide guidance.

Pre-app attendees from the city typically include a land use planner, a building plan reviewer, and may include an engineer, fire department reviewer, or environmental reviewer depending on the project. This is the single opportunity in the permitting process to ask specific questions and get authoritative answers before you submit.

When a Pre-Application Conference Is Recommended

Not every project benefits from a pre-app. For routine projects — straightforward additions, ADUs in standard configurations, simple commercial TIs — your architect’s existing knowledge of Seattle’s requirements is sufficient and a pre-app adds unnecessary time. Pre-apps add real value for:

• Projects with unusual site conditions: steep slopes, streams, shoreline, critical areas
• Projects near the edge of code compliance: height limits, setback variances, lot coverage at the maximum
• Change of occupancy: converting residential to commercial, or changing commercial use types
• Historically significant structures: any project on a landmarked building or in a historic district
• Projects requiring multiple permits: building permit + shoreline permit + design review + environmental review
• New construction in non-standard zones: industrial zones, commercial zones with residential components, overlay districts
• Projects with fire access questions: waterfront sites, properties with limited street frontage, large footprint buildings

How to Request a Pre-Application Conference

Pre-application conferences are requested through the City of Seattle’s permitting portal (Seattle Services Portal). You submit:

• Project address and parcel number
• Description of proposed project
• Preliminary site plan and floor plans (draft — not permit-ready)
• List of specific questions for city staff
• Pre-application conference fee (currently $1,500–$3,000 depending on project complexity)

After submission, SDCI schedules the meeting — typically 4–8 weeks from request submission. The meeting is usually 2 hours.

What to Bring to Your Pre-Application Conference

The pre-app is most valuable when you bring specific, well-formed questions — not general inquiries. Your architect should prepare:

• Site plan showing existing and proposed conditions
• Preliminary floor plans for each level
• Elevation sketches showing the proposed massing
• Zoning compliance summary (existing and proposed floor area, lot coverage, height, setbacks)
• Specific questions numbered and organized by department

The meeting produces written notes from SDCI summarizing the guidance provided. These notes are not binding — they are staff opinions, not formal decisions — but they provide a reliable indicator of how your project will be reviewed.

Pre-Application Conference vs. Early Design Guidance

Early Design Guidance (EDG) is the first formal meeting in Seattle’s design review process for projects that trigger full design review. It is a public meeting before the Design Review Board. A pre-application conference is different: it is a private staff meeting, available to any project, and focused on code compliance questions rather than design quality evaluation. EDG is part of design review; a pre-app can precede any permit type.

Using Pre-App Guidance in Your Design

The information from a pre-application conference should directly inform the design development that follows. If the planner indicates that a proposed use triggers a variance, that is a design problem to solve — not just a regulatory note to acknowledge. Your architect should treat pre-app guidance as design constraints and respond to it through the design rather than accepting it as an obstacle.

Pre-Application Conferences at Piper Cole Architects

For projects that benefit from a pre-application conference, Piper Cole Architects prepares all materials, attends the meeting with the client, and integrates the guidance into the design process. We have participated in pre-application conferences across multiple project types in Seattle and know how to frame questions to get useful, actionable answers from city staff.
