Their conclusions came after two days of graphic evidence and detailed testimony at the inquest into the death of Travis Paranteau.
The 27-year-old committed suicide while on remand at the centre in June 2010 on charges that included sexual assault.
The recommendations of the jury were not read in court, but Dawn Knudsen, Paranteau's sister, says they include covering exposed piping in cells, which Paranteau used to hang himself.
She says the jury also wants staff at the facility to have up-to-date CPR and First Aid training.
While she's satisfied with the recommendations, Knudsen isn't convinced her brother was treated properly.
"I found that he, as probably some other inmates, were bouncing around in the remand quite frequently," said Knudsen.
Corrections workers testified Paranteau started out in a 24-hour observation unit when he arrived at the jail in 2009, but would go back and forth depending on his psychiatric assessments.
The inquest heard he was in a low-risk unit at the time of his death.
In the end, Knudsen believes her brother saw no way out because he wasn't being heard when it came to both his charges and his depression.
Paranteau's mother and two sisters attended the entire inquest and were allowed to ask witnesses questions.
Coroner Brent Gough thanked the family, saying "this is a difficult process and your participation has made it better."
May Paranteau, Travis Paranteau's mother, tearfully thanked the person jury, saying she hopes the recommendations will save lives.
"It's a horrible thing to go through, when all you have left is memories," she said.
