Section 21145.04, Subd. 1(f) bars exterior and interior displays visible from outside the dwelling, and the City's sign code separately confirms no temporary or permanent sign is permitted for a home occupation or licensed home occupation.

Full Breakdown

Plymouth treats home occupation signage more strictly than nearly any other use in the City Code. 04, Subd. 1 lists the general standards every home occupation, permitted or licensed, must follow, and Subd. 1(f) states there shall be no exterior display or exterior signs or interior display or interior signs which are visible from outside the dwelling. That means even a small nameplate or window sign advertising a home-based hair stylist, tutor or repair business is prohibited if it can be seen from the street or a neighboring yard.

05, Subd. 04 forbids. The rule applies uniformly across every residential zoning district, FRD, RSF-1 through RSF-4, and RMF-1 through RMF-5, because home occupations are accessory to the residential use rather than a standalone commercial use. A home business owner may still use a doorbell nameplate identifying the resident rather than the business, but any signage naming the business, its hours, or its services violates the section if visible from outside.

Violations & Fines

The Zoning Administrator enforces the no-signage rule during the license review and any follow-up inspection authorized by Section 21145.06. Posting a visible business sign is treated as noncompliance with the home occupation's general provisions, which can lead to denial of a pending license application, revocation of an existing home occupation license, or a demand to immediately remove the sign.

Frequently Asked Questions

Can I put a small sign in my window for my home business in Plymouth?
No. Section 21145.04, Subd. 1(f) bars any interior or exterior display or sign for a home occupation that is visible from outside the dwelling, and Section 21155.05, Subd. 21 separately confirms no temporary or permanent sign is permitted for a home occupation.
Does the sign ban apply to both permitted and licensed home occupations?
Yes. Section 21145.04, Subd. 1's general provisions, including the no-signage rule in Subd. 1(f), apply to every home occupation regardless of whether it falls in the permitted track under Subd. 2 or the licensed track under Subd. 3, since both tracks must first satisfy Subd. 1.
What about a plain nameplate with my family name?
Plymouth's residential sign rules allow a nameplate sign up to four square feet under Section 21155.06, Subd. 2(b), but that provision identifies the resident, not a business; any wording that promotes the home occupation itself still falls under the Section 21145.04, Subd. 1(f) ban.
