Planning commission debates whether repurposed semi‑trailers qualify as cargo containers under accessory storage rules

At a Planning Commission meeting, commissioners discussed amending Green River City Code section 10‑18‑2 to clarify whether repurposed semi‑trailers count as cargo containers or as accessory storage buildings.

The discussion focused on ambiguous language in current definitions and how the city should treat trailers removed from their axles, painted, or otherwise repurposed for storage. One commissioner summarized the question: "there's a little bit of ambiguity of where semi trailer actually fits" and asked whether the code should treat an axle‑removed semi as a cargo container. City planning staff noted the ordinance currently lists several transportable structures under "not an accessory storage building" and separately defines "cargo containers" using wording aimed at shipping containers and transportation equipment.

Commissioners proposed several possible clarifications: explicitly excluding single‑axle trailers unless converted (for example, removed from axles), requiring exterior painting in a single neutral color, prohibiting placement on frontage streets, and limiting cargo containers to one per acre in commercial contexts. One commissioner suggested defining a cargo container to include a semi trailer only if it has been removed from its axles; another advocated adding language to require that a fully enclosed trailer be placed on a permanent support and painted.

Members also noted the ordinance adopted Feb. 9, 2021, and said units that existed before that date may be grandfathered. Commissioners expressed concern about creating enforcement loopholes and emphasized the need to balance property owners' access to low‑cost storage with neighborhood appearance and safety. Staff indicated painting and other exterior requirements already appear elsewhere in the ordinance and that the commission should decide whether to move semi‑trailers into the cargo container definition or explicitly exclude them.

No ordinance amendment was adopted at the meeting. Commissioners asked staff to draft proposed language that would: (1) clarify whether semi‑trailers removed from axles are cargo containers; (2) require painting in one solid neutral color; (3) limit cargo containers to one per acre in commercial zones (or otherwise specify the per‑acre rule); and (4) prohibit placement on frontage streets or require placement in the rear yard. The item will return for further review at a future meeting.

Commissioners and staff repeatedly cautioned that the discussion was preliminary and procedural: the item was listed for discussion only, and any change will require a formal amendment, public notice, and votes at later meetings.
