Planning Commission weighs limits on shipping containers, sheds and accessory structures

The commission considered accessory-structure rules in Division 3 (Section 9.9), focusing on where and how detached structures and storage containers should be regulated.

Chair Lee emphasized the original purpose for setbacks: privacy, emergency access and fire separation. Commissioners generally preferred limiting encroachments into required setbacks and indicated small administrative allowances (for example, 10% encroachment) may be appropriate for minimal edits. Staff clarified accessory dwelling units are regulated separately.

Shipping containers generated the most debate. Staff said the current code allows them only on a temporary basis (flood recovery, moving, temporary construction storage). The draft proposes limiting permanent containers to industrial zoning, capped at about 10 feet in height and prohibiting double-stacking. Several commissioners and community examples showed that, when well-designed and painted to blend in, a single container placed in a commercial lot can be unobtrusive; others urged restricting or limiting permanent commercial uses to preserve neighborhood character.

Commissioners also discussed small backyard sheds, the practicality of current 4-foot separation requirements from property lines, and the distinction between engineering and building-code separation needs and on-the-ground compliance; staff said building-code fire-resistive rules drive some setbacks and that small sheds under certain sizes do not require building permits.

What happens next: staff will review building-code constraints, clarify where shipping containers may be allowed, confirm height and stacking limits, and propose language distinguishing temporary from permanent container use.

Provenance: accessory-structure discussion began at the consultant's introduction to Section 9.9 and continued through storage-container exchanges.
