Summary
San Marcos Municipal Code Chapter 10.38 lets the City bill the host of a disturbance of the peace for every police or code-enforcement response after the first. Once officers deliver a written 'Notice of Violation: First Response' citing Penal Code § 415, any second or subsequent call to the same address becomes a recoverable debt.
10.38.010 - Purpose. It is the purpose of this chapter to provide a source of recovery for the costs incurred by the City in returning a second and subsequent time to the scene of a disturbance of the peace. 10.38.030 - First Response. (a)During the first response to a disturbance of the peace occurring on private property, the responding officer may, among other things, deliver to the responsible person or persons a "Notice of Violation: First Response" which shall contain a message substantially as follows: "This notice of violation is given to you as a result of a first response of the City of San Marcos to a disturbance of the peace occurring in violation of Penal Code, Section 415. You will be charged all City personnel and equipment expenses incurred as a result of any second or subsequent response to this location".

Full Breakdown
010. 020(a) defines the 'Responsible Person' broadly as whoever owns the property, is in charge of the premises, or organized the event causing the disturbance; if that person is a minor, their parent or guardian becomes jointly and severally liable for the response costs. 040 requires the City to compute and bill the actual response costs, which become a debt to the City recoverable through a civil action, including reasonable attorney's fees. 050 lets the City also notify the owner directly that a subsequent-response notice has been issued against the location.
Violations & Fines
There is no criminal charge under Chapter 10.38 itself; instead, the City bills the responsible party (or their parent, if a minor) for the actual personnel and equipment cost of every response after the first written warning. Unpaid charges become a civil debt collectible in court, including the City's attorney's fees.
