Full Breakdown
E set the Building Form standards for the Residential Neighborhood (RN) district, Lynnwood's base residential zone for single-family homes, duplexes, triplexes, fourplexes, cottage housing, townhouses and stacked flats. The Detached Configuration table lists Maximum Building Height at 35 feet, and the Attached Configuration table repeats the identical 35-foot maximum. 2 for four units, so a larger building is only permitted by adding units within the same 35-foot envelope rather than by exceeding it. The Detached Configuration table also caps Maximum Street-Facing Entry Spacing at 40 feet, while the Attached Configuration table instead requires a Minimum Street Facing Entrances count of one entrance for one to two units and two entrances for three to four units.
RN is Lynnwood's implementation of Washington's HB 1110 middle-housing mandate, which required the city to permit up to four units per lot in this zone; the 35-foot cap applies regardless of how many of the four allowed units a project includes. The section was last amended by Ordinance 3492, Sections 3 through 5, in 2025, following adoption by Ordinance 3481, Section 7, in 2025, after the prior Title 21 zoning code, which used different height limits, expired June 30, 2025.
Violations & Fines
A building exceeding the 35-foot height limit in the RN district cannot receive site plan or building permit approval from the City of Lynnwood's Community Development Department, which checks every new construction and addition against the RN Building Form table. A project already under construction that is found to exceed 35 feet faces a stop-work order and must be modified to comply before occupancy is granted.
