Unlike incorporated cities, Colton falls under the jurisdiction of Clackamas County's land use and zoning regulations, which significantly shapes how ADU (Accessory Dwelling Unit) contractors operate in this area. The rural character of Colton, surrounded by forests and farmland, means that ADU projects here often involve unique site considerations such as well water systems, septic systems, and larger lot sizes — all of which experienced local ADU contractors must be well-versed in handling.
