Bellevue residential building height: what homeowners should check

Start with the zoning district

Bellevue's official building-height guidance says the maximum depends on the property's zoning. Confirm the parcel's zone before applying a number from a nearby project or an old plan.

• Check the city zoning map and current Land Use Code table.
• Confirm whether an overlay, shoreline area, critical area, or recorded approval adds another limit.

Height starts at average existing grade

For a single-family house, Bellevue measures to the highest point of the roof from average existing grade around the proposed footprint. The city describes elevations taken at 10-foot intervals and a site plan with two-foot contours. This makes a survey and a clear grading plan important on sloped lots.

The facade limit is a separate check

Bellevue also applies a maximum individual facade height of 40 feet to most new single-family houses and additions. A design can comply with the overall zoning height and still need adjustment because one downhill facade is too tall.

Our take

Ask the surveyor and architect to show the grade points, average calculation, roof peak, and tallest facade on one diagram. That is much safer than discussing height as a single number without the measurement method.
