Summary
Seattle requires Design Review before permitting most downtown development: full design review applies at 50,000 square feet of gross floor area in DOC1, DOC2 or DMC zones, and at 20,000 square feet in DRC, DMR, DH1, DH2, PMM (outside the Pike Place Market Historical District), IB or IC zones. A Design Review Board applies citywide and neighborhood design guidelines before SDCI issues a permit.
Subject to the exemptions in subsection 23.41.004.B, design review is required in the following areas or zones when development is proposed that exceeds a threshold in Table A or Table B for 23.41.004: a. Multifamily; b. Commercial; c. Seattle Mixed; and d. Downtown. ... Table B for 23.41.004 — Design review thresholds by size of development in downtown and industrial zones. A. All DOC1, DOC2, or DMC zones — 50,000 square feet or greater — Full design review. B. All DRC, DMR, DH1, DH2, PMM zones outside the Pike Place Market Historical District, IB, or IC zones — 20,000 square feet or greater — Full design review.

Full Breakdown
002). 004: design review is required in Multifamily, Commercial, Seattle Mixed and Downtown zones once a project exceeds the size thresholds in Table A or Table B. 004 sets the downtown-specific bar: projects of 50,000 square feet or more in DOC1, DOC2 or DMC zones need full design review, and projects of 20,000 square feet or more in DRC, DMR, DH1, DH2, PMM (outside the Pike Place Market Historical District), IB or IC zones need it too. Smaller downtown projects can qualify for streamlined or administrative review instead under Table A's size bands (roughly under 8,000 square feet is exempt; 8,000-35,000 square feet is administrative; 35,000 square feet and up is full review).
B). C). A the Board synthesizes community input, identifies guideline priorities, judges design compliance, and recommends to the SDCI Director whether to approve, condition or deny requested departures from Title 23 development standards. The Director, not the Board, makes the final permit decision.
Violations & Fines
Design Review isn't optional once a project crosses the Table A/B threshold: SDCI won't issue a Master Use Permit until the Board process and Director sign-off are complete. Building or using a structure "without first obtaining the permits or authorizations required" is a Title 23 violation under SMC 23.90.002, exposing the owner to a cumulative civil penalty of up to $150 per day for the first ten days of noncompliance and up to $500 per day after that under SMC 23.90.018.
