Yes. California law lets the values of separate thefts be added together into one theft count, and it gives prosecutors more than one way to do it. Whether that pushes a case from petty theft to grand theft, and whether you face one count or several, depends on which rule the prosecution uses and what the evidence shows about each incident.

The older rule: one intention, one general impulse, one plan

The classic version of this rule comes from the California Supreme Court’s decision in People v. Bailey (1961) 55 Cal.2d 514. When a series of takings, each too small to be grand theft alone but together above the grand theft line, are all motivated by one intention, one general impulse, and one plan, the offense is one grand theft rather than a string of petty thefts, and the values are added together. The Legislature has since written a version of this test into Penal Code section 487(e): if distinct but related acts, including acts against different victims or in other counties, together exceed $950, their value may be aggregated to charge one count of grand theft when the acts share that one intention, impulse, and plan. The statute gives examples of evidence that can support that finding: the acts involve the same defendant or defendants, are substantially similar in nature, or occur within a 90-day period. The list is not exhaustive, and no single item on it is required.

Workplace takings have their own rule. Under section 487(b)(3), money or property that an employee, agent, or servant takes from an employer or principal can be totaled over any 12 consecutive months to decide whether the theft is grand theft.

This question often comes up in shoplifting cases involving more than one visit or item, and in grand theft cases where an employer or investigator adds up several smaller incidents. When the prosecution relies on the one-plan theory, CALCRIM No. 1802 tells jurors who find more than one theft that grand theft requires proof of two more things: that the combined value was over $950, and that the defendant was motivated by one intention, one general impulse, and one plan in obtaining the property. If grand theft is not proved, the thefts the jury finds proven are petty thefts.

A second, broader aggregation rule

Since Proposition 36 took effect on December 18, 2024, Penal Code section 490.3 has given prosecutors another option for theft and shoplifting cases: the value of property or merchandise from one or more acts of theft or shoplifting may be aggregated into a single count or charge, and the total decides the degree of the theft. Unlike section 487(e), the text of section 490.3 does not repeat the one-intention, one-impulse, one-plan requirement. CALCRIM No. 1801 reflects this with a separate bracket stating that the defendant committed grand theft if the combined value of all the property or merchandise referenced in the count is more than $950, with no common-plan finding. Section 490.3 is recent, so how courts apply it, including whether they will require any connection between the acts, is a question to raise with your lawyer.

One plan does not mean only one count

Both aggregation statutes say the value “may” be combined, so aggregation is a tool the prosecution can use. And a shared plan does not limit the case to a single count when the takings were separate acts. In People v. Whitmer (2014) 59 Cal.4th 733, the California Supreme Court held that separate and distinct acts of theft can support multiple grand theft convictions even when they were all part of one overarching scheme. The court distinguished Bailey, which involved a single false statement followed by a series of payments, and disapproved readings of Bailey that would allow only one conviction for separate and distinct acts committed under one scheme. Arguing that several takings were all “one plan” therefore does not, by itself, reduce several counts to one.

Depending on the values involved, combining incidents can turn several petty thefts into one grand theft, while charging them separately can mean several counts. Which approach the prosecution takes, and whether the facts support it, both affect your exposure.

Facts that affect how incidents are charged

Whether incidents share one intention, impulse, and plan, or were separate and distinct acts, is a factual question, so the details of each incident matter:

  • How much time passed between the incidents, and whether they fall within a 90-day period
  • Whether the incidents were substantially similar in method, place, or type of property
  • Whether the same person or people were involved each time
  • Whether each taking was its own act with its own intent, or one act that produced a series of payments or receipts
  • Existing receipts, transaction logs, and records that show how the incidents were connected or separate
