Gonzalez v. Mathis, 20 Cal. App. 5th 257

Background

Plaintiff Luis Gonzalez, an independent-contractor window washer, fell from an exposed two-foot roof ledge while accessing a skylight at defendant John Mathis's residence and sued for negligence/premises defects.
Gonzalez alleged three dangerous conditions: (1) a parapet wall forcing access along the unguarded narrow ledge, (2) dilapidated/slippery shingles, and (3) lack of tie‑off points.
Gonzalez had regularly worked on the roof, knew of the shingles and lack of railings/tie‑offs, and testified he used the outside ledge because interior access was blocked by piping/equipment.
Mathis moved for summary judgment invoking Privette and its progeny (generally barring contractor claims against hirers), arguing neither exception (retained control or concealed hazard) applied; he relied on 2015 photos/video suggesting interior passage was feasible.
The trial court granted summary judgment for Mathis; the appellate court reversed, finding triable factual issues about hirer liability under Kinsman and that retained‑control evidence was insufficiently shown by Mathis.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Does Privette bar Gonzalez's action?	Privette applies but exceptions save claim.	Privette bars recovery because Gonzalez was an independent contractor.	Privette applies generally, but exceptions may allow recovery; case not resolved by blanket bar.
Retained‑control exception (Hooker) — did hirer retain and exercise control contributing to injury?	Carrasco's directions about order of work and telling Gonzalez to tell employees to use less water, plus Mathis being sole party able to fix roof, show retained control.	Carrasco's instructions were limited and did not direct how work was done; mere authority to fix hazards without affirmative exercise is insufficient.	No triable issue shown on retained‑control theory — plaintiff presented no evidence that Mathis exercised retained control in a way that affirmatively contributed to the fall.
Hazardous‑condition/landowner duty (Kinsman) — concealed vs. open hazards and avoidability	Kinsman permits liability where hazard is concealed or where an open/known hazard cannot reasonably be avoided; Gonzalez says he could not reasonably avoid the ledge.	Kinsman applies only to concealed hazards; alternatively, photos/video prove interior route was feasible so hazard was avoidable.	Triable issue exists under Kinsman whether the ledge was avoidable: photos/video taken years later do not conclusively refute Gonzalez’s testimony that interior access was impracticable at the time.
Was summary judgment appropriate?	Factual disputes over avoidability and hirer authority preclude summary judgment.	Documentary/video evidence conclusively disproves plaintiff’s account.	Summary judgment reversed — reasonable minds could differ, so issues must go to jury.
