Building codes and property taxes play a crucial role in determining whether off-grid homes can be built on land that is not zoned as farm or forest in Oregon. While zoning laws in Oregon are strict, and most private land is zoned as farm, forest, or mixed farm/forest, building codes and property taxes can also impact the ability to build off-grid homes. In some cases, building codes may require certain standards that could make off-grid living more challenging. Additionally, property taxes may be higher for off-grid homes, especially if they are not zoned as farm or forest. It is important to research and understand all regulations and laws before building an off-grid home in Oregon to ensure compliance and avoid any legal issues.
