Building Setbacks & Zoning in Marysville, WA

Marysville maintains 123 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Marysville falls on the strict-to-permissive spectrum compared to other cities.

Setback Rules

Marysville's density and dimension table at Marysville Municipal Code § 22C.010.080(2) sets minimum street, side and rear yard setbacks for every residential zone. Street setbacks run 20 to 25 feet, side yards 5 to 10 feet, and rear yards 20 to 25 feet depending on the zone, with case-by-case reductions and a mandatory 50-foot buffer against adjoining agricultural land under § 22C.010.090.

Key details: Street setback: 20-25 ft, varies by zone. Side yard setback: 5-10 ft, varies by zone. Rear yard setback: 20-25 ft, varies by zone. Ag-zone buffer: 50 ft minimum, no reduction. Street setback reduction: To 10 ft with 20-ft driveway.

Building without the required setback is enforced under Marysville Municipal Code § 4.02.040 as a Title 22C land use violation: a first offense runs $150 for a noncommercial property and $250 for a commercial one, a second offense $300 or $500, and a third violation within two years becomes a misdemeanor punishable by up to $1,000 and 90 days in jail. Each day of noncompliance is a separate infraction.

Lot Coverage Limits

Marysville Municipal Code § 22C.010.080(2) caps building coverage and total impervious surface for every residential zone. Building coverage tops out at 40 percent in the NR-4.5, NR-6.5 and WR-R-6-18 zones and 50 percent in R-12, R-18 and R-28. Impervious surface, meaning any hard surface that sheds rainwater, is capped at 45 to 50 percent in the NR zones and 70 to 75 percent in the R zones under § 22C.010.090(6).

Key details: Building coverage, NR zones: 40% max. Building coverage, R zones: 50% max. Impervious surface, NR zones: 45-50% max. Impervious surface, R zones: 70-75% max. 50% impervious threshold: Subdivisions filed after 5/8/2017.

Exceeding the building coverage or impervious surface cap is a Title 22C land use violation enforced under Marysville Municipal Code § 4.02.040: a first offense costs $150 for a noncommercial lot and $250 commercial, a second offense $300 or $500, and a third violation within two years becomes a misdemeanor carrying up to $1,000 and 90 days in jail, with each day a separate infraction.

Structure Height Limits

Marysville sets base residential height limits of 30 feet in the NR-4.5 and NR-6.5 zones and up to 45 feet in R-18 and R-28, letting builders go higher by adding extra setback, but never past an absolute 60-foot ceiling.

Key details: Base height, NR-4.5/NR-6.5: 30 feet. Base height, R-18/R-28: 45 feet. Absolute max height, any zone: 60 feet. Height bonus trade-off: 1 extra setback ft per ft over base. Citation: MMC §§ 22C.010.080, .090(5).

A structure built above its zone's base height without the matching extra setback fails plan review and can draw a stop-work order or correction notice under Marysville's Title 22A civil code-enforcement process, including daily civil penalties until it is fixed.

The Bottom Line

Marysville'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 Marysville is broadly strict or permissive.

Keep in mind that Marysville can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
