Who reviews commercial building plans?
Either DSPS or a certified municipal inspector, depending on the municipality. Larger cities have their own reviewers; smaller jurisdictions route plans through DSPS.

Changing the use classification (e.g., retail to restaurant) triggers a full review that may require additional fire suppression, accessibility, and ventilation upgrades.
