Full Breakdown
Tehama County Code § 17.04.020(D) requires a home occupation to 'produce no evidence of its existence beyond the premises, except signs of not more than one square foot,' alongside a ban on noise, smoke, odors and vibration detectable off the property. That one-square-foot cap is far below the four-square-foot sign the county allows a licensed bed-and-breakfast under § 17.08.010(I)(3), underscoring how tightly home-business signage is limited. The rule governs only unincorporated Tehama County; Red Bluff, Corning and the City of Tehama set their own home-business sign standards.
Violations & Fines
Posting a sign larger than one square foot, or any other visible or audible sign of the business's existence, forfeits the home occupation's by-right status and invites zoning code enforcement.
