California Penal Code 667.5: Prior Prison Term Enhancements After SB 136

California Penal Code section 667.5 adds prison time to a new felony sentence when the defendant already served time for a prior felony. A 2020 reform gutted most of the statute. What survives today: a three-year add-on for each prior violent felony prison term when the new offense is also a violent felony, and a one-year add-on that now applies only when the prior prison term was for a sexually violent offense.1California Legislative Information.

How the Extra Time Gets Added

A 667.5 enhancement is not a separate charge. It is time stacked on top of the sentence for the new felony, and it must run consecutively. Each qualifying prior counts on its own: two qualifying priors mean the enhancement is added twice, three priors mean three times.

The prior must have involved actual custody. A felony conviction that ended in probation or a suspended sentence does not count. The statute treats the defendant as being in custody through the official discharge date, which includes any period of parole or post-release community supervision.1California Legislative Information.

The Three-Year Violent Felony Enhancement

Subdivision (a) is now the heaviest part of the statute. It applies when the new offense is a violent felony listed in subdivision (c) and the prior prison term was also for a violent felony on that same list. Three years get added for each qualifying prior, consecutive to everything else.1California Legislative Information. California Code PEN 667.5 – Enhancement of Prison Terms

A defendant with three prior violent felony prison terms faces nine extra years on top of the base sentence. The math compounds fast.

The three-year enhancement has a ten-year washout. If the defendant stayed out of prison custody and picked up no new felony conviction for a full decade between discharge on the prior and the new offense, that old prison term cannot be used.

What Counts as a Violent Felony

Subdivision (c) lists 24 categories. The list is broader than the label suggests and includes:

  • Murder, voluntary manslaughter, and attempted murder
  • Rape, sodomy by force, oral copulation by force, lewd acts on a child, continuous sexual abuse of a child, and sexual penetration by force
  • Any robbery, carjacking, and first-degree burglary where a non-accomplice was in the residence
  • Kidnapping
  • Mayhem
  • Arson of an inhabited structure or property
  • Any felony punishable by life or death
  • Any felony where the defendant personally inflicted great bodily injury or personally used a firearm, when charged and proved
  • Assault with intent to commit a specified felony
  • Extortion or witness intimidation committed in connection with gang activity
  • Use of a weapon of mass destruction

The firearm and great-bodily-injury categories matter because they pull in offenses that are not otherwise on the list. Assault that would not qualify on its own becomes a violent felony when the defendant personally inflicted great bodily injury.1California Legislative Information.

The One-Year Enhancement After SB 136

Before 2020, subdivision (b) added one year for every prior felony prison term, violent or not. Someone with four old burglary convictions automatically picked up four extra years. Senate Bill 136 took effect January 1, 2020, and cut that provision down to a narrow exception.2California Legislative Information. SB 136 – Sentencing

Under the current version, the one-year enhancement applies only when the prior prison term was for a “sexually violent offense” as defined in Welfare and Institutions Code 6600. That definition covers a narrow set of predatory sex crimes. For every other type of prior felony, the one-year add-on no longer exists.1California Legislative Information. California Code PEN 667.5 – Enhancement of Prison Terms

Where the one-year enhancement still applies, it comes with a five-year washout. Five years free of prison custody and free of any new felony conviction after discharge on the prior sexually violent offense wipes it out.

Retroactive Relief for Old One-Year Enhancements

SB 136 only ran forward. People already serving sentences padded with one-year enhancements for non-violent priors got nothing at first. Senate Bill 483 changed that on January 1, 2022, declaring those old one-year enhancements legally invalid.3California Legislative Information. SB 483 – Sentencing: Resentencing to Remove Sentencing Enhancements

One exception: one-year enhancements based on a prior sexually violent offense remain valid, because they still have a basis under the current statute.

SB 483 put the burden on the correctional system, not the incarcerated person. The California Department of Corrections and Rehabilitation and county jail administrators were required to identify everyone in custody whose sentence included an invalid enhancement, then forward each person’s name, date of birth, and case number to the sentencing court.3California Legislative Information. SB 483 – Sentencing: Resentencing to Remove Sentencing Enhancements

Once the court gets the referral, it verifies the invalid enhancement, recalls the sentence, and resentences with the enhancement removed. The new sentence must be shorter than the original unless the court finds, by clear and convincing evidence, that a reduced sentence would endanger public safety. That standard is a high bar. The court cannot assume risk; it has to point to specific evidence of a likelihood of physical injury or serious danger to others.3California Legislative Information. SB 483 – Sentencing: Resentencing to Remove Sentencing Enhancements

Anyone who believes they qualify but has not been identified should raise it through their defense attorney or file a request directly with the sentencing court.

Getting the Enhancement Dismissed

Even when the prosecution proves every element, the court is not always required to impose the enhancement. Penal Code 1385 lets a judge dismiss any sentencing enhancement “in the furtherance of justice,” and the statute lists nine mitigating circumstances that weigh heavily in favor of dismissal:4California Legislative Information. California Code PEN 1385 – Dismissal in Furtherance of Justice

  • The enhancement would contribute to a racially disparate outcome
  • More than one enhancement is alleged in the case (all beyond the first should be dismissed)
  • Applying the enhancement would push the total sentence past 20 years
  • The current offense is connected to a qualifying mental illness
  • The current offense is connected to the defendant’s own history as a victim of childhood trauma
  • The current offense is not a violent felony under 667.5(c)
  • The defendant was a minor when they committed the current or prior offense
  • The enhancement is based on a conviction more than five years old
  • A firearm was involved but was inoperable or unloaded

Proving any one of these creates a presumption favoring dismissal. The court should dismiss unless it finds that doing so would endanger public safety, meaning a likelihood of physical injury or other serious danger. The court can also consider circumstances outside the list. This discretion reaches the three-year violent felony enhancement under 667.5(a).4California Legislative Information.

How the Prosecution Proves the Prior

The prosecution has to establish every element: that the defendant was convicted of a qualifying felony, actually served a prison or jail term for it, and finished that term without enough washout time before the new offense. For a subdivision (a) enhancement, the prosecution also has to prove the prior offense falls within the subdivision (c) list. Defense challenges typically target whether the prior genuinely qualifies, whether the custody records line up, or whether the washout period ran.
