What matters for project planning
This is the trade local designation touches most often, and it catches people by surprise because painting feels like maintenance rather than alteration. On a designated property, changes visible from the street can be reviewable, and that can extend to color and to finish on trim, porches and siding -- so confirming status for the specific parcel before purchasing anything is the cheap step. The stormwater program has nothing to say about paint. What it does bear on is site work incidental to a repaint, such as regrading or replacing a walk while access equipment is already on site.
