AB336 modifies Penal Code section 452, which criminalizes ‘‘unlawfully causing a fire,’’ by attaching explicit monetary fines to felony offenses, clarifying penalties for different fire outcomes, and reinforcing consecutive sentencing for crimes committed by incarcerated persons. The bill specifies a fine not to exceed $10,000 for felony variants of the offense that cause great bodily injury, cause an inhabited structure or property to burn, or involve structure or forest land.
Beyond monetary penalties, the bill keeps the existing felony/misdemeanor distinctions and preserves shorter jail terms for lesser property fires, while adding a provision that treats fires started on merchant premises to facilitate organized retail theft as an aggravating factor at sentencing. Together these changes expand the court’s punitive tools and create new practical considerations for charging, plea bargaining, and post-conviction custody calculations.
At a Glance
What It Does
The bill amends Penal Code §452 to make three felony variants of ‘‘unlawfully causing a fire’’ eligible for an additional fine up to $10,000, preserves the misdemeanor classification for simple property fires, requires sentences to run consecutive when the offender is already confined, and lists fires on merchant premises connected to organized retail theft as aggravating conduct.
Who It Affects
Prosecutors and defense attorneys handling arson and wildfire cases, judges setting fines and sentences, incarcerated individuals who start fires while confined, county jails and state prisons managing consecutive terms, and retailers where fires associated with organized retail theft occur.
Why It Matters
By adding an explicit fine ceiling and tightening consecutive-sentence rules, the bill increases the maximum legal exposure for defendants and gives prosecutors more leverage in negotiations. It also raises implementation questions about collection of fines, proof of recklessness in complex wildfire causation, and overlap with existing arson and restitution laws.

What This Bill Actually Does
AB336 keeps the core of California’s unlawful-fire offense — the crime consists of recklessly setting, burning, or causing to be burned a structure, forest land, or property — but adds concrete financial and sentencing mechanics that change how cases will be handled in practice. For the more serious felony permutations (fires that cause great bodily injury; fires that burn inhabited structures or inhabited property; and fires of structures or forest land), the bill authorizes courts to impose a fine up to $10,000 in addition to the statutory prison terms already listed.
That means judges can now stack a monetary penalty onto existing imprisonment ranges.
For less serious incidents — fires of property that do not meet the felony thresholds — the bill leaves the offense as a misdemeanor, with the long-standing exception that burning one’s own property isn’t criminal unless it injures someone else or someone else’s property. The bill also directs that when a person commits this offense while already serving a sentence in state prison, a prison camp, or county jail, any new sentence must run consecutive to the existing one, effectively extending total time behind bars for in-custody offenses.Finally, AB336 instructs courts to treat an offense committed within merchant premises to facilitate organized retail theft (as defined elsewhere in statute) as a factor in aggravation at sentencing.
That ties retail-theft-related fires to harsher sentencing considerations and signals prosecutorial intent to treat those incidents more severely. Taken together, these changes adjust both the scale of punishment and the calculus for charging and plea bargaining in fire-related prosecutions.
The Five Things You Need to Know
The bill adds an explicit fine up to $10,000 to each felony variant of Penal Code §452 (subsections (a)–(c)).
Subsection (a) (fire causing great bodily injury) remains a felony with prison terms of two, four, or six years, now also subject to up to $10,000 in fines.
Subsection (d) preserves the misdemeanor classification for unlawfully causing a fire of property and keeps the self-property burning exception unless another person or property is harmed.
The bill requires that sentences for §452 convictions committed while an offender is confined (state prison, prison camp, or county jail) run consecutive to the sentence for which the person was then confined.
The statute adds that fires set on merchant premises to facilitate organized retail theft count as a factor in aggravation during sentencing.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Felony for fires causing great bodily injury — added fine
This subsection addresses the most serious outcome: a fire that causes great bodily injury. The statutory prison terms (two, four, or six years) remain unchanged, but AB336 explicitly permits the court to impose a fine up to $10,000 in addition to imprisonment. Practically, that means convictions under (a) expose defendants to combined custodial and monetary penalties rather than prison-only exposure.
Felony for burning inhabited structures or property — fine added
Subsection (b) targets fires that burn inhabited structures or inhabited property and keeps the felony sentencing ranges (two, three, or four years). The bill layers the same maximum $10,000 fine onto these convictions. The combination of multi-year exposure plus a monetary penalty increases total legal exposure and can affect post-conviction financial obligations and plea bargaining dynamics.
Felony for structure or forest land fires — fine added
This subsection covers fires of structures or forest land that do not rise to the inhabited-structure or great-bodily-injury categories; punishments (16 months, two, or three years) remain but now carry the same $10,000 fine ceiling. This is the primary provision that reaches many wildland and structure-adjacent fires and therefore is the vehicle most likely to carry the new monetary penalty in typical wildfire prosecutions.
Misdemeanor classification for property fires and self-burning exception
Subsection (d) leaves lower-level property fires as misdemeanors and clarifies that burning one’s own personal property is not criminal unless it injures another person or another person’s structure, forest land, or property. This preserves a narrowing carve‑out that prevents trivial or purely self-harming conduct from triggering criminal liability while still exposing harmful consequences to prosecution.
Consecutive sentences for in-custody offenses; organized retail theft aggravation
Subdivision (e) requires that any §452 sentence imposed on a person who committed the offense while confined (in state prison, a prison camp, or county jail serving any sentence) be consecutive to the sentence for which they were confined. Subdivision (f) directs courts to treat fires committed within merchant premises to facilitate organized retail theft as a sentencing aggravator. The two provisions together increase punishment exposure for in-custody offenders and signal harsher treatment for fires tied to retail-theft operations.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- State and local prosecutors — gain greater charging leverage because convictions can now bring both imprisonment and a sizable fine, strengthening plea-bargaining position and sentencing arguments.
- Retailers and merchant-property owners — receive a statutory signal that fires linked to organized retail theft will be treated more severely, which can influence private security policies and civil recovery strategies.
- Landowners and local governments in fire-prone areas — potentially benefit from stronger deterrent language and increased penalties that could reduce reckless fire starts and offset some costs through fines.
Who Bears the Cost
- Defendants (especially low-income individuals) — face added monetary exposure on top of imprisonment, raising risks of unpayable judgments and longer-term financial consequences.
- County jail and state prison systems — may see longer aggregate custody time because in-custody offenses must be served consecutively, increasing bed needs and operational costs.
- Public defenders and indigent defense systems — will face more complex sentencing calculations and potentially greater pressure in plea negotiations, increasing workload and litigation over ability-to-pay disputes.
Key Issues
The Core Tension
The central tension is straightforward: AB336 strengthens punitive tools (monetary fines, mandatory consecutive terms, and a retail-theft aggravator) to increase deterrence and punishment for wildfire-related fires, but it does so without addressing collection mechanics, causation complexity, or the disproportionate burden monetary penalties place on indigent defendants — forcing a trade-off between harsher sanctions and equitable, practicable enforcement.
The bill’s addition of a flat fine ceiling up to $10,000 is simple on its face but creates several implementation headaches. Courts must decide whether and how often to impose the fine in cases already carrying significant custody exposure; judges commonly consider ability to pay, victim restitution priority, and existing statutory limits, but AB336 does not specify distribution of collected fines or how they interact with restitution orders.
That omission raises questions about whether fines will meaningfully compensate victims or simply become uncollectible judgments that burden defendants.
Requiring consecutive sentences for offenses committed while confined achieves a predictable punitive outcome but shifts costs to correctional systems and may deter in-custody reporting or mitigation measures. The recklessness mental state also invites evidentiary disputes in wildfire cases where causation is complex: weather, utility infrastructure, and third-party ignition sources frequently factor into investigations.
Finally, treating fires on merchant premises tied to organized retail theft as aggravating merges two distinct policy problems — retail theft and fire-starting — and may lead to uneven charging if prosecutors use the aggravator in cases where the link to organized retail theft is tenuous or where policy priorities differ across jurisdictions.
