Radius Fulton rest home in Caversham would require significant repairs and its residents had been relocated, Mr Pickford said.
Council building inspection and environmental health teams had visited 11 properties where assistance with flooding issues had been requested and more visits would be done this afternoon

Civil Defence made the announcement just before 10am and said the Emergency Operations Centre would remain active as the recovery from the flooding got under way
Mayor Dave Cull praised the way people worked together to get through yesterday's event.
“It was great to see the whole community – residents, businesses, emergency services, health, DCC staff and contractors and many others – working together to get through yesterday’s flooding,” he said
“The early and proactive preparations by all involved ensured that the community coped as well as it possibly could with the downpour.”
DCC Chief Executive Sue Bidrose earlier saod they were aware of 13 properties, most of them in South Dunedin, which had floodwater enter living areas.
''Our building inspection and environmental health teams are out this morning assessing the affected homes.''
“We urge anyone who had floodwater enter their living areas and hasn’t let us know, to call us on 03 477 4000 or register on the DCC website at www.dunedin.govt.nz/adverse-weather so we can provide assistance as needed,” Dr Bidrose said.

History repeated itself yesterday for many residents, who faced similar flooding in 2015 and wake this morning facing another clean-up. A state of emergency was declared at 2.20pm. Dunedin had received 18mm of rain an hour in the previous two hours.
"That is more than our system is designed to cope with, even though it has operated exactly how it is intended to," Mayor Dave Cull said.
Overall, 108.4mm of rain fell up until 9pm yesterday.
Emergency services, which had been stretched on Wednesday to deal with a large fire in Burnside, were flat out once more, with multiple calls to deal with weather-related mayhem.
Residents at Radius Fulton Care Centre, in South Dunedin, suffered badly in the 2015 floods and were again evacuated yesterday.
Managing director Brien Cree said the Southern District Health Board, Civil Defence, emergency services and family members were helping move the elderly residents to safer premises.
He did not know when residents would be able to return.
A spokeswoman said plans had been put in place after 2015 for a similar incident, and the relocation of the 89 residents was going smoothly.
There were no reports of flood-related injuries.
The Dunedin City Council opened two evacuation centres — at Caledonian Gym and at Mosgiel’s Memorial Park hall — but they were closed at 7pm due to lack of demand.
However, the state of emergency remained in place overnight and would be reviewed this morning.
South Dunedin’s stormwater system was unable to cope with the 2015 deluge, and struggled with the amount of rain which fell in a short time yesterday.
"It was just the sheer volume of rain in such a short period of time meant that some of the groundwater entered the wastewater system, and that’s what caused the problem," Civil Defence controller Leanne Mash said.
Wastewater and floodwater mingled in Surrey St, Forbury, and more South Dunedin streets were expected to be affected.
"We are treating all floodwater in South Dunedin as if it were potentially contaminated and it should be avoided," Ms Mash said.
She did not know how many homes and businesses were affected by flooding in South Dunedin. Earlier estimates were 800 premises might be at risk.
"Right now we are working through all the reports that have come through police or to our own call centres and combining them together into an action plan.
"We are also asking people to go on line and fill out a form if they have had floodwater through their home or business so we can get them into the system and inspect their property."
Various roads around Dunedin would remain closed until they were clear of water, and Surrey St and Hillside Rd were closed due to concerns about wastewater flooding.
Coastal settlements avoided major damage, although Aramoana Domain flooded and rock walls collapsed near Waipuna Bay.
The road to Aramoana was closed last night due to debris.
Authorities had feared a predicted king high tide about 5pm would cause serious issues, especially on the West Harbour and Otago Peninsula roads.
State Highway 88 to Port Chalmers will need to be reduced to one lane today for repairs to a wastewater pump station affected by a power cut.
Two cruise ships are due in port today, and the road works will be scheduled around peak transport times.
Several schools closed early yesterday in an effort to keep cars off the roads when rainfall and flooding was expected to peak.
South Dunedin schools would be able to open today, depending on how much floodwater remained nearby, Ms Mash said. The Forbury Park trotting meeting yesterday did not go ahead. Masters Games participants are arriving today, and the condition of sports grounds will be checked this morning.
The Taieri was also hit hard, with extensive flooding in Mosgiel and its surrounds.
"There has been a significant amount of surface water in Mosgiel ... and it has been too great for the system to cope with," event controller Richard Saunders said.
"There have been some flooding issues out there."
Civil Defence was still monitoring the Silver Stream last night but expected no serious problems after the rain had eased off.The wider Otago region did not escape the deluge.
Roxburgh, which was cut off by flash floods in November, was again dealing with major landslips which had made the three main routes in to the town impassable.
An estimated 100mm of rain fell in the central Otago town yesterday.
Transport Agency senior network manager John Jarvis said highways would remain closed overnight before hopefully reopening this morning.
"We haven’t had any massive rocks that have come down in this event, it’s been more finer material that’s come down, but a lot of it."
