Summary
San Marcos zones home occupations under Municipal Code § 20.400.100 and flatly bars any appreciable increase in traffic. The rule covers both foot and vehicle traffic, meaning client visits, deliveries, or parked cars that noticeably change the neighborhood's traffic pattern can put a home business's license at risk.
C. Use Regulations. No person shall conduct a home occupation use unless such home occupation use is conducted in conformity with all the following criteria: ... 6. No appreciable increase of traffic, pedestrian or vehicular, shall result from such use.

Full Breakdown
100 governs home occupations in Residential (R), Agricultural (A), and Mixed Use (MU-1, MU-2) zones. 08, and every standard in this section must be met before that license can issue. 7, which bars parking any fleet vehicle, equipment truck, or food truck at the home business site unless the applicable zone expressly allows it: only resident vehicles may be stored on-site. Other standards in the same list cap floor space devoted to the business at 200 square feet unless the Director approves more, bar outside employees (only residents of the dwelling may work there), prohibit display or storage of goods or merchandise visible from outside, and limit the business to utility services normal for a residence.

Violations & Fines
Failure to meet any Section 20.400.100 standard, including the traffic limit, is grounds for the City to deny, suspend, or revoke the home business license issued under Chapter 3.08. The Development Services Department investigates complaints and can require the operation to stop generating additional traffic or shut the home occupation down entirely; unresolved violations also expose the property to standard municipal code enforcement, including citation.
