Off-grid home design in Oklahoma is subject to zoning regulations that govern property use and construction. While there are no restrictions on the size or type of off-grid homes, local zoning laws determine what is allowed on a property. Agricultural (A-1) zoning is common and qualifying as a farm can result in tax benefits and sales tax exemptions. However, agricultural and rural lands have restrictions on commercial businesses, and land zoned for conservation or preservation has many restrictions on property use. Off-grid electric systems are legal, but there are no state rebates or property tax exemptions for solar. Net metering laws are in place for grid-tied systems. Alternative waste systems are in a legal gray zone and must be approved by the Department of Environmental Quality. Septic systems require soil tests and permits, with non-certified installers needing to have systems inspected. Domestic water use is allowed without permits, but restrictions on usage apply. While there are relaxed laws concerning water usage and zoning compared to other states, Oklahoma is drought-prone, and water is a precious resource. In conclusion, off-grid home design in Oklahoma is subject to zoning regulations, and those interested in pursuing such a lifestyle should consult local laws and regulations before building.
