Summary
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.
Height limits may be increased when portions of the structure which exceed the base height limit provide one additional foot of street and interior setback beyond the required setback for each foot above the base height limit; provided, that the maximum height may not exceed 60 feet.
(b) Multiple-family developments, located outside of the downtown neighborhood, abutting or adjacent to areas zoned as single-family, or areas identified in the comprehensive plan as single-family, may have no more floors than the adjacent single-family dwellings, when single-family is the predominant adjacent land use.
(6) Applies to Each Individual Lot.
(a) The 50 percent impervious surface coverage applies to complete land use applications for subdivisions submitted on or after the effective date of Ordinance 3057, adopted May 8, 2017; provided, however, in the case of approved development applications that have not yet started construction, an applicant may file for a minor revision to the approved land use application in accordance with MMC § 22G.010.260.

(i) Regional uses shall be established at the time of permit review; or

Full Breakdown
Marysville's density and dimension table, Marysville Municipal Code Section 22C.010.080(2), sets base residential heights of 30 feet in the NR-4.5 and NR-6.5 zones, 35 feet in R-12 and WR-R-6-18, and 45 feet in R-18 and R-28. Section 22C.010.090(5)(a) lets a structure rise above its zone's base height only if it adds one extra foot of street and interior setback for every foot of extra height, and even then the building can never exceed 60 feet. Multifamily buildings next to single-family areas are also capped at the neighboring homes' floor count.
Violations & Fines
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.
