Jersey's States Assembly has approved new regulations, based on the Grenfell Tower inquiry, to improve fire safety for islanders living in tall blocks of flats.
It is estimated that around 8,500 islanders live in buildings which are four storeys or higher.
Politicians have unanimously approved the new rules, which are expected to bring several improvements.
The regulations will come into effect from April 2027.
Home Affairs Minister Mary Le Hegarat says investment will be needed from building owners to ensure they fit regulations.
"Residents should be confident that their building was built with good fire safety features.
"These regulations will require fire safety features to be regularly checked, which gives them the best chance of working effectively in a fire.
"They also require better information to be given to residents and firefighters to help them in the event of a fire."
The regulations focus on tall blocks of flats due to the number of people living in them deemed a high-risk.
The Home Affairs Minister says there is also a difficulty when it comes to rescuing people from above the fourth floor.
Deputy Mary Le Hegarat says the Grenfell fire inquiry has highlighted areas of improvement.
"I want our buildings to benefit from this learning to ensure they are well equipped if a serious fire occurs."
