Clyde Hill residential zoning
Clyde Hill residential zoning and setbacks
Clyde Hill uses one R-1 residential district, but the side-yard requirement changes with lot area. This makes the parcel's surveyed area, width, legal-lot status, and original grade especially important.

|---|---|
| 15,000 sq ft or more | 15 ft on each side |
| More than 10,000 but under 15,000 sq ft | 10 ft on each side, plus upper-story angle plane |

Parcel-specific checks
What can change the table
- The code also lists 100 feet of minimum frontage and 100 feet of minimum lot depth for a standard R-1 lot.
- Clyde Hill does not use FAR in the base R-1 table. Height, setbacks, structural coverage, and impervious coverage control instead.
- Original grade matters for the 25-foot height limit. Preserve survey evidence before demolition or grading.
- A nonconforming lot, accessory structure, private covenant, street condition, or tree issue can require separate analysis.
How to use this guide
Turn a zone row into a useful screen
- 1
Find the parcel on the city's current zoning map and copy the complete zone name.
- 2
Read the full row, table footnotes, and definitions. Do not use only the front setback.
- 3
Check corner-lot yards, access easements, critical areas, shorelines, trees, overlays, and recorded restrictions.
- 4
Use a boundary and topographic survey to place the setbacks against the actual lot.
- 5
Have the city or project team confirm any uncertainty before the design is fixed.
