What Redmond Inspectors Check
Redmond has significant tree canopy regulations — the Tree Retention and Land Clearing code is actively enforced. If your exterior project involves removing trees over 6 inches DBH (diameter at breast height), you may need a tree removal permit in addition to your building permit. Inspectors also pay attention to impervious surface limits, as Redmond is within the Sammamish River watershed.
