Building Setbacks & Zoning in Bellingham, WA

If you live in Bellingham or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Bellingham has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Lot Coverage Limits

Bellingham caps standard multifamily lot coverage at 35% of the site under BMC 20.32.040(D), but BMC 20.32.050(C) lets developers build up to 45%, 55%, 65%, or 75% coverage by meeting stricter wall-to-property-line ratios and covered-parking requirements.

Key details: Standard multifamily cap: 35% of site area. Level 4 maximum: 75% coverage. Trade-off for higher coverage: Covered parking required. Excluded areas: View, shoreline, flood, steep slope.

Exceeding the applicable coverage cap without qualifying for a higher option level, or building under the option without meeting the wall-ratio and covered-parking conditions, is a zoning violation subject to city enforcement.

Structure Height Limits

Bellingham's Residential Single zone caps buildings at 35 feet measured to the roof peak from grade at the wall, or 20 feet under the alternate on-site grade method.

Key details: Zone: Residential Single (RS). Height limit, Definition No. 1: 35 feet, wall grade to roof peak. Height limit, Definition No. 2: 20 feet, on-site grade method. Enforcement: Civil infraction, $500-$1,000 fine.

Exceeding the height limit or building without required approval is a civil infraction under BMC 20.52.010: up to $500 for a first offense, $1,000 for a second, each day a separate violation.

Setback Rules

In Bellingham's Residential Single (RS) zone, main buildings need a 5-foot side yard, a 10-foot rear yard, and a front yard set 50 feet from the street centerline.

Key details: Side yard setback: 5 feet from property line. Rear yard setback: 10 feet from property line. Front yard setback: 50 feet from street centerline. Zone: Residential Single (RS).

Building within these minimum yards without an approved variance or recorded plat exception is a zoning violation; the city can deny occupancy or require the structure be removed.

The Bottom Line

Bellingham's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Bellingham is broadly strict or permissive.

These rules come from Bellingham's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
