Summary

In the City of Sonoma, a home occupation approved through the standard administrative permit may host only one client, patient, or pupil on site at any given time, per Municipal Code § 19.50.040(E)(5). The code separately bars any traffic increase beyond what is normal for a residential neighborhood.

11. Traffic Generation. The home occupation shall not generate additional pedestrian or vehicular traffic substantially greater than that normally associated with residential uses in the surrounding area; ... ... 5. Allowable On-Site Visits. The home occupation may allow only one client, patient, or pupil to be present at any one time (except for child day care facilities).

Full Breakdown

040(E) lists extra limits that apply to a home occupation approved through the city's administrative permit process, and limitation 5 caps on-site client traffic hard: only one client, patient, or pupil may be present at any one time, with the sole exception of licensed child day care facilities. 040(B)(11) backs this up, prohibiting any home occupation from generating pedestrian or vehicular traffic substantially greater than what is normal for a residential area. 040(F)(4) requires a conditional use permit reviewed by the planning commission for teaching organized classes of more than six persons at a time.

040(B)(13). 040(E)(3), so a converted garage entrance used by visiting clients would itself be out of compliance. These limits apply only within the City of Sonoma; homes in the surrounding unincorporated Sonoma Valley are regulated by Sonoma County, not this code.

Violations & Fines

Exceeding the one-visitor limit is grounds for denial or revocation of the home occupation permit under § 19.50.040(I), and constitutes a code violation under Chapter 1.12 SMC: fines run from $100 for a first infraction up to $500 for a third within one year, with continued noncompliance also risking the business license required by § 19.50.040(H).

Frequently Asked Questions

Can two clients visit my home-based business at the same time in Sonoma?
No. Under Sonoma Municipal Code § 19.50.040(E)(5), a home occupation approved through the city's administrative permit may have only one client, patient, or pupil on site at any one time. The only carve-out is for licensed child day care operations, which follow different visitor rules.
Can I teach a class of ten students from my home in Sonoma?
Not under the administrative permit. Section 19.50.040(F)(4) requires a conditional use permit, reviewed by the planning commission, for teaching organized classes of more than six people at a time. Below that threshold, and within the one-visitor rule, the simpler administrative permit applies.
How many deliveries can my home business receive each day?
Up to two. Sonoma Municipal Code § 19.50.040(B)(12) limits every home occupation, regardless of permit type, to two deliveries per day, and separately restricts operating hours to between 7:00 a.m. and 10:00 p.m. except for child day care facilities.
