Summary
Every food establishment in San Marcos must keep its premises free of rats, mice, roaches, ants and other pests. If the Health Officer finds an infestation, the operator gets a written 30-day abatement notice, and missing that deadline means the health permit is summarily suspended and the establishment closed.
The owner, operator or manager of every establishment shall take every precaution to keep the premises free and rid of rats, mice, roaches, ants and other vermin and pests. Whenever it shall appear to the Health Officer that any establishment is infected with rodents, vermin or pests, a written notice shall be given to the person owning, operating or managing the establishment that said infestation shall be abated within 30 days from the date of the written notice. Failure to comply with said written notice within 30 days shall constitute a violation of the provisions of this chapter, and the Health Officer shall suspend the permit summarily and close such establishment until said nuisance has been abated.

Full Breakdown
330 places an affirmative duty on the owner, operator or manager of every permitted food establishment to take every precaution to keep the premises free and rid of rats, mice, roaches, ants and other vermin and pests. The rule is proactive, meaning the operator cannot wait for a citation; the establishment must already be free of infestation before an inspector shows up. When the County Health Officer determines during inspection that an establishment is infested with rodents, vermin or pests, the Health Officer must serve written notice to the person owning, operating or managing the establishment, and that notice starts a 30-day clock to abate the infestation.
120. 330 treats that failure as a violation of the chapter and directs the Health Officer to summarily suspend the permit and close the establishment until the infestation has been abated; there is no grace period or partial credit once the 30 days lapse. 480, complaints about restaurant rodent problems in San Marcos go to County environmental health inspectors, who issue the notice, verify abatement, and lift the suspension once the premises pass reinspection.
Violations & Fines
A written notice of infestation gives the operator 30 days to abate. Failing to comply within that window is a violation of Chapter 8.04 that triggers summary suspension of the health permit and mandatory closure of the establishment until the Health Officer confirms the infestation has been eliminated.
