Full Breakdown

Orange County's home occupation rules in the unincorporated area require the business to stay invisible from the street: no exterior evidence of the operation, no more than one client on-site at a time, and under subsection (c)(8) of Section 7-9-104, no signs at all, not even a small nameplate. The home occupation must run entirely inside the dwelling's enclosed living area and can't change the residence's principal character. Home occupations are permitted only where the zoning district allows them and where the operator meets all other subsection (c) standards, including maintaining required residential off-street parking.

Violations & Fines

Violating the Zoning Code's home occupation standards is a misdemeanor under Section 7-9-130.3, punishable by up to a $2,500 fine and six months in county jail, with each day of continued violation a separate offense.

Frequently Asked Questions

Can I put a sign in my yard advertising my home business in unincorporated Orange County?
No. Section 7-9-104(c)(8) of the county's home occupation standards states 'There shall be no signs,' so any exterior signage for a home-based business is prohibited on unincorporated county land.
Does this sign ban apply inside cities like Anaheim or Irvine?
No. This is a county code provision that only governs unincorporated Orange County. Anaheim, Irvine, Santa Ana and the county's other 34 cities each set their own home-business sign rules.
