Yes, Peruvian peppertree is rated fire resistant, with its clearest guidance tied to irrigation and maintenance.
The University of California Agricultural Extension Service includes Schinus molle among plants for fire protection on irrigated hillsides. For that finding, fuel volume must be minimized, the tree watered to its needs, and accumulated litter removed. Diputació de Girona and Bombers de la Generalitat de Catalunya give Schinus molle a “recommended” garden-suitability verdict, assuming species-specific care. Their five-level qualitative method combines fire evidence with fuel structure, maintenance, origin, invasiveness, and fire-service experience.
Two California compilations reinforce the favorable verdict. The University of California Forest Products Laboratory found Peruvian peppertree recommended by 12 earlier references for high-fire-risk areas. Earlier lists often lack a scientific basis, the laboratory warns. Both compilations flag undefined rating terms, with Diablo Firesafe Council describing most terms that way. Diablo includes Peruvian peppertree in its favorable fire-performance table, whose threshold is three or more favorable references.
The balance therefore supports treating Peruvian peppertree as fire resistant, especially where the University of California’s irrigation and maintenance conditions are followed. Fire performance is not the only consideration, however: the species is flagged as invasive in two jurisdictions. Local invasive-species rules should be checked before it is chosen for landscaping.

Fire-resistant — location does not change the cited classification.
The guide presents itself as fire performance ratings for common landscape plants in a fire-prone California setting. FireApproved publishes 104 exact owners as republished California context. It is not an independent rating, a current endorsement, or parcel suitability.
The UC Forest Products Laboratory says the guide covers properties of common California landscaping plants and was prepared for California fire agencies. FireApproved publishes 130 exact owners at historical California publication scope. The report is a 1997 compilation, not a current endorsement, site rating, or independent test of every row.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Native and introduced range evidence
These are exact U.S. botanical-area records from the cited range source. Native and
introduced describe biogeographic relationship, not fire performance or planting approval.
Doubtful and extinct rows stay visible but do not count as current presence.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
Schinus molle (California pepper) appears in the source's conditioned examples for landscaping irrigated hillsides. Fuel volume is to be minimized, plants watered to their needs, and accumulated litter removed.
Schinus molle is rated “RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.

“Table 1: favorable fire performance rating in 3 or more references (refs 5,9,11,13,17,22,25,30,37,40,41,53)”
The Diablo Firesafe Council Guide to Plants lists Schinus molle (Peruvian pepper tree, California pepper tree) as tree, evergreen, in Table 1: plants with a favorable fire performance rating in 3 or more references. The guide cites 12 of its 57 numbered references for this row (5,9,11,13,17,22,25,30,37,40,41,53). The guide states the ranking terms in its underlying references were mostly undefined and makes no attempt to rank within the list, and that fire performance is compromised without maintenance.
