The owners of about 40 holiday cabins in the South Australian town of Beachport have been banned from using them over summer in a drawn-out process sparked by fire safety concerns.

Meg Longstaff and her husband bought one of the units three years ago, but will not be able to spend Christmas there with their son and dog — and may never stay in the unit again.

"When the unit came up, it honestly was like a dream come true for us," Ms Longstaff said.

"We're very normal people; we're not super well-off.

" This was an affordable, good-faith investment, but it has turned into a bit of a nightmare in the past few months, not knowing where we stand. "

Fire safety risk discovered

Owners of semi-permanent units at the Southern Ocean Tourist Park can sell them on the open market.
