Architect vs. General Contractor in Seattle: Who Does What?

One of the most common points of confusion for first-time homeowners planning a major project is understanding the difference between an architect and a general contractor — and why you typically need both.

What an Architect Does

An architect is a licensed design professional who translates your goals into buildable drawings. Their work includes:

• Designing the spaces, layout, and appearance of the building
• Producing permitted construction documents
• Managing the permit process with the city
• Coordinating structural and mechanical engineers
• Reviewing contractor work during construction to verify it matches the drawings

An architect’s primary deliverable is drawings and specifications. They do not build.

What a General Contractor Does

A general contractor (GC) builds what the architect draws. Their work includes:

• Bidding the project based on permit drawings
• Hiring and managing subcontractors (framing, plumbing, electrical, etc.)
• Ordering and managing materials
• Managing the construction schedule and budget
• Pulling the building permit and managing inspections

A GC’s primary deliverable is a completed building.

Do You Always Need Both?

For projects requiring a building permit — additions, ADUs, new construction, structural renovations — you will need both. The permit requires architectural drawings. Construction requires a licensed contractor.

For cosmetic work (paint, floors, cabinet replacement that does not move walls) you can go straight to a contractor. But the moment you are moving walls, adding space, or touching structure, you need an architect first.

Design-Build: A Third Option

Some firms combine architecture and construction under one contract. This can streamline communication but reduces competitive bidding. See our post on architect vs. design-build for a full comparison.
