An arson conviction in California doesn't have one clearance path — it has at least four, and picking the wrong one wastes months. The right strategy depends on whether you served probation or state prison time, whether your charge was filed as a wobbler, and what's actually blocking you today: a job, a firearm, a license, or an immigration proceeding.
Best overall for most arson convictions: Penal Code 1203.4 expungement, if you completed probation without a state prison sentence. Best for wobbler-level arson charges: felony-to-misdemeanor reduction under Penal Code 17(b). Best for convictions that included state prison time: a Certificate of Rehabilitation. Best for the most serious or lingering cases: a Governor's Pardon.
- To expunge an arson conviction in California, Penal Code 1203.4 works only if you completed probation, not state prison, on the original sentence.
- Wobbler-level arson charges under Penal Code 451 can sometimes be reduced to a misdemeanor first under Penal Code 17(b) before or instead of expungement.
- A Certificate of Rehabilitation fits arson convictions that included state prison time and are otherwise ineligible for standard expungement.
- A Governor's Pardon is the path for the most serious arson records still blocking licensing, gun rights, or immigration status in 2026.
- Cole Law, led by attorney Allison Cole, reviews the underlying case file before recommending which of these four routes to pursue.
Why this matters
Arson convictions carry consequences that outlast the sentence: firearm bans, licensing board denials, and background check flags that follow you into 2026 and beyond. The mistake most people make is filing a standard 1203.4 petition without checking whether their specific arson charge — a straight felony versus a wobbler, probation versus prison — even qualifies.
Allison Cole and the team at Cole Law start every arson case by pulling the actual disposition: which subsection of Penal Code 451 applied, what sentence was imposed, and what's changed since. That single step determines which of the four remedies below is realistic, and which one is a dead end that costs you filing fees and half a year of waiting.
What makes the best strategy for expunging an arson conviction
- Match to the actual sentence. Probation-only cases fit 1203.4; state prison time usually points toward a Certificate of Rehabilitation instead.
- Wobbler status. Only certain arson charges under Penal Code 451 can be reduced under 17(b) — arson involving an inhabited structure or great bodily injury generally cannot.
- Effect on firearm rights. Some remedies restore gun rights, others don't; this matters more for arson than for many other felonies given how prosecutors charge it.
- Licensing and background check visibility. A reduction or expungement changes what shows on most background checks, but not all of them, and not for every licensing board.
- Time to relief. A 1203.4 petition can move faster than a Certificate of Rehabilitation, which carries its own statutory waiting period.
- Whether the conviction itself was sound. If the facts point to mistaken identity or a wrongful charge, none of the above apply — a factual innocence petition does.
Arson relief options at a glance
| Legal path | Best for | Standout feature | Key limitation |
|---|---|---|---|
| Penal Code 1203.4 expungement | Probation-only arson convictions | Dismisses the conviction under state law once probation is complete | Not available if you served state prison time on the arson count |
| Felony-to-misdemeanor reduction (PC 17(b)) | Wobbler-level arson charges | Can be filed before or alongside expungement | Straight-felony arson (inhabited structure, injury) is not eligible |
| Certificate of Rehabilitation | Convictions that included state prison time | Doubles as an automatic Governor's Pardon application for many offenses | Requires a minimum period of California residency and a waiting period tied to the offense |
| Governor's Pardon | The most serious or still-restrictive arson records | Only relief that can restore certain firearm rights after a straight felony | Discretionary and can take longer than the other three paths |
1. Penal Code 1203.4 expungement: best for probation-only arson convictions
Penal Code 1203.4 lets you withdraw a guilty or no-contest plea, enter a not-guilty plea, and have the case dismissed once probation is successfully completed. For arson specifically, this only works if the sentence was probation rather than a state prison term — that single fact decides eligibility before anything else gets reviewed.
Penal Code 1203.4 pros:
- Dismisses the conviction under California law, not just seals it
- Available the moment probation ends, without a long statutory waiting period
- Covers most lower-degree arson and unlawful-fire charges under Penal Code 452
Penal Code 1203.4 cons:
- Unavailable if state prison time, rather than probation, was imposed
- Does not restore firearm rights lost due to a felony arson conviction
- Certain licensing boards can still see and consider the underlying conviction
Best for: anyone whose arson case resolved with probation, not prison. Verdict: Pursue now if your sentence matches this profile — this is the fastest of the four routes.
2. Felony-to-misdemeanor reduction (Penal Code 17(b)): best for wobbler arson charges
Some arson charges under Penal Code 451 are wobblers, meaning they can be charged and later treated as either a felony or a misdemeanor. Reducing the charge first, then pursuing expungement on the misdemeanor, often produces a cleaner outcome than expungement alone.
Felony reduction pros:
- Changes how the conviction reads on most background checks going forward
- Can be filed alongside a 1203.4 petition in the same case
- Reduces certain licensing and employment barriers tied specifically to felony status
Felony reduction cons:
- Straight-felony arson — an inhabited structure or great bodily injury — is not eligible, regardless of actual damage
- Judges retain discretion and can deny the reduction even on a qualifying wobbler
- Doesn't erase the conviction on its own; it changes its classification
Best for: lower-degree, property-only arson charges filed as wobblers. Verdict: Consult first — a felony reduction lawyer in California can confirm wobbler status before you file anything.
3. Certificate of Rehabilitation: best for arson convictions that included state prison time
When a state prison sentence rules out standard 1203.4 relief, a Certificate of Rehabilitation is the next step. It requires at least five years of continuous California residency after release, plus an additional statutory waiting period specific to the offense, and it results in a court order recognizing rehabilitation.
Certificate of Rehabilitation pros:
- Available for felony arson convictions that served state prison time
- Automatically forwards as a Governor's Pardon application for many qualifying offenses under state law
- Carries weight with licensing boards as documented proof of rehabilitation
Certificate of Rehabilitation cons:
- Requires years of residency and a waiting period before you can even file
- Not a dismissal of the conviction — it's a certification alongside it
- The hearing is discretionary; a judge can deny it
Best for: arson convictions where a prison sentence took 1203.4 off the table. Verdict: Pursue once the residency and waiting-period clock has run — file the Certificate of Rehabilitation petition as soon as you're eligible.
4. Governor's Pardon: best for the most serious or still-restrictive arson records
A Governor's Pardon is the broadest form of relief available in California and the only one of the four that can restore certain firearm rights lost after a straight felony arson conviction. For California residents, it's usually reached through the Certificate of Rehabilitation process rather than filed as a standalone petition.
Governor's Pardon pros:
- Can restore rights that survive expungement and reduction, including some firearm rights
- Carries the most weight on applications where any felony history is disqualifying
- Available even after straight-felony arson convictions that no other remedy touches
Governor's Pardon cons:
- Fully discretionary and typically the slowest of the four paths
- For most residents, it depends on first securing a Certificate of Rehabilitation
- Out-of-state residents file a different, direct application process
Best for: the most serious arson records still limiting licensing, employment, or firearm rights after 2026. Verdict: Wait and build the record first — a Governor's Pardon petition works best after a Certificate of Rehabilitation is already granted.
A fifth path worth naming
If the underlying arson charge was based on mistaken identity, a coerced plea, or facts that don't hold up, none of the four remedies above are the right tool — a factual innocence petition is. It's a narrower, harder-to-win path, but it's the only one that can remove the record entirely rather than dismiss, reduce, or certify around it.
“An arson conviction that never involved state prison time shouldn't still be blocking a background check in 2026 — that's what Penal Code 1203.4 exists to fix.”
How I ranked these
The order above follows accessibility, not severity: 1203.4 sits first because it's available to the largest share of probation-only cases and moves fastest. Certificate of Rehabilitation and Governor's Pardon sit lower because they carry residency requirements, waiting periods, and discretionary hearings that slow things down, even though they reach further for serious convictions.

Which path should you choose?
If you completed probation on an arson conviction, file the Penal Code 1203.4 petition first — it's faster and requires no waiting period beyond probation itself. If the charge was a wobbler and still shows as a felony, pair a 17(b) reduction with it. If a state prison sentence ruled out 1203.4, the Certificate of Rehabilitation is the realistic next move, and it can carry you straight into a Governor's Pardon application without a second filing. For anyone unsure which category their case falls into, that's the first question worth answering before filing anything in 2026.
FAQ
What's the best way to expunge an arson conviction in California?
Penal Code 1203.4 expungement is the best route when the arson conviction resolved with probation rather than state prison. If prison time was served, a Certificate of Rehabilitation is the more realistic path.
Is arson eligible for expungement under Penal Code 1203.4?
Yes, but only if you completed probation on the arson conviction rather than serving state prison time. Straight-felony arson sentences that included prison generally need a Certificate of Rehabilitation instead.
Can a felony arson conviction be reduced to a misdemeanor?
Only if the specific arson charge was filed as a wobbler under Penal Code 451. Arson involving an inhabited structure or great bodily injury is a straight felony and is not eligible for reduction under Penal Code 17(b).
How long does a Certificate of Rehabilitation take for an arson conviction?
It requires at least five years of continuous California residency after release, plus an additional statutory waiting period tied to the offense, before you can even file the petition.
Does an expunged arson conviction still show up on background checks?
An expunged conviction is dismissed under California law, but some licensing boards and certain federal background checks can still see the original case. It depends on who's running the check and why.
Is a Governor's Pardon necessary if I already have a Certificate of Rehabilitation?
Not necessarily — for many offenses, a granted Certificate of Rehabilitation automatically forwards as a pardon application. A separate pardon petition is mainly needed for out-of-state residents or specific excluded offenses.
Can I own a firearm again after expunging an arson conviction?
Standard expungement under Penal Code 1203.4 generally does not restore firearm rights lost due to a felony conviction. A Governor's Pardon is the remedy most likely to address firearm restoration after arson.
How much does it cost to expunge an arson conviction in California?
Costs vary by court and case complexity, including filing fees and any attorney fees for preparing the petition. Check current filing fee schedules with the court handling your original case.
One last thing
The detail most people miss: California treats arson under Penal Code 451(b) and (c) — fires that endanger an inhabited structure or cause great bodily injury — as ineligible for 17(b) reduction no matter how minor the actual property damage turned out to be. The statute is written around the risk created, not the outcome, which is why two arson cases with nearly identical damage can land in completely different relief categories in 2026.
