Summary

Unincorporated Chelan County zones its working farmland as Commercial Agricultural Lands (AC) under Chelan County Code § 11.30.020, which sets a ten-acre minimum lot size, a thirty-five-foot height cap, and a mandatory one-hundred-foot setback keeping new houses away from neighboring AC-zoned cropland and orchards.

These county ordinances apply to unincorporated areas of Chelan County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

All development in this zone shall meet the applicable provisions of the Chelan County Code, including without limitation the following: ... (1) Minimum lot size: ten acres, which measures to the centerline of adjoining public rights-of-way, which may be modified one time for: ... (6) Setbacks from Agriculture. No new dwelling unit shall be placed within one hundred feet of a property zoned as commercial agricultural lands (AC).

Full Breakdown

04 district use chart. 030, or the one-time lot-size reduction for an existing dwelling described later in the same section. 170 allows more, and lot coverage cannot exceed thirty-five percent. Front yards run twenty-five feet from the property line or fifty-five feet from the street centerline, whichever is greater; rear yards are twenty feet; side yards are ten feet, widening to twenty-five feet on a corner lot's street side. Subsection (6) adds the agricultural buffer: no new dwelling may be placed within one hundred feet of AC-zoned land.

The administrator can shave that buffer by up to twenty percent for lots legally created before September 9, 1997, and neighbors can waive it entirely with a notarized agreement recorded at the county auditor's office, which then binds future enlargements or additional dwellings to a fresh waiver. Plats, short plats, and building permits within five hundred feet of designated agricultural, forest or mineral land must carry a recorded notice warning buyers that nearby commercial farming may bring noise, dust or spraying at certain times of year.

Violations & Fines

Community Development checks minimum lot size, setbacks and the agricultural buffer at plat and building permit review, and a proposal that crowds a dwelling inside the one-hundred-foot AC buffer without a recorded waiver or an administrator-approved modification will be denied. Once built, encroachments are handled through Chelan County's standard code enforcement and Title 16 violation process, which can require the structure be relocated or the owner obtain the missing recorded waiver from the adjoining agricultural owner before the county will clear the file.

Frequently Asked Questions

How big does a lot have to be in Chelan County's AC zone?
Ten acres, measured to the centerline of the adjoining public right-of-way, under Chelan County Code § 11.30.020(1). That minimum can be reduced only once, through a cluster subdivision or planned development, a fractional lot of at least half the district minimum in a plat, a boundary line adjustment, or the one-time reduction available for an existing dwelling.
How close can a new house be built to farmland in unincorporated Chelan County?
Not within one hundred feet of any parcel zoned commercial agricultural lands (AC), per § 11.30.020(6). The administrator may cut that buffer by up to twenty percent for lots created before September 9, 1997, and the adjoining owners can waive it entirely with a notarized agreement recorded at the county auditor's office.
What is the maximum building height in the AC zone?
Thirty-five feet, per Chelan County Code § 11.30.020(3), unless the accessory structure height provisions of § 11.88.170 permit additional height for a specific use. Lot coverage in the AC zone is separately capped at thirty-five percent of the total lot area under subsection (4).
