That might be helpful to go thru verbally with them and you could make the assessment on what the place looks like using the scale

Will give you a chance to do a rough assessment as to what level they are at - FWIW I am a hoarder in recovery, 3 years ago I was in the RED now I am in the Green, it been a long slow process.
I have 2 support workers who come to me weekly and they get the stuff out of the house asap, I get a list of stuff to complete for the following week.
They are employed by a charity but their funding is provided by the local housing office to ensure that I have a hope of maintaining my tenancy and have a safe place to live.
I have been in the past to the post where sectioning for my mental health was discussed as I was living in such squalor but ended up doing an industrial clearance of the house, without the mental health side addressed within a couple of years it was far worse.
Almost 3 years ago, I engaged with these support workers with the aim of getting this under control, they provide support, chat and physically sorting stuff as we carry on.
I have addressed informally the reasons why thru discussions with them for hoarding, MH team has been a chocolate teapot in that regard.
If you look at the clutter picture scores I was at 9, now I am at worst a 2. It was my physical health decline which made things a hell of a lot worse added by a manic episode and a need to hold onto things.
The manager of the support service apparently thought I was paying lip service to them and that I wasnt actually going to engage and they would be signing me off their books within 3 months (she didn't say it to me). She has eaten her words, I engaged fully and was signed off at almost 2 years with a lot of progress.
I was taken back on after an agreed period and I had made more progress. I still have a bit to go and then its the maintenance period, where they will check in monthly for 3 years to ensure I am maintaining.
For an example of the scales -

I've addressed my root cause and its taken time to get back from that point, I still have a way to go but I am going in the right direction.
Yes to the fire service, community safety officer in the local council, they have done fire checks for me and provided extra smoke alarms, co2 alarms and other stuff.
Like your DSis op my problem started out as a mental one, then my physical health spiralled downhill, I wasnt coping and buying more stuff "to help" but then couldn't find it in the middle of things so was rebuying.
I wasnt physically able to move stuff and go thru it on my own, that's what the 2 support workers did they physically put stuff in front of me to make a decision on.
Keep, bin, donate, recycle - the bin and recycle stuff went off to the local dump before our weekly session was over so that it didn't clog up my bins altogether as it would have. The recycling went away in that car run as well in bags which then was emptied at the tip into appropriate sections.
The donate piles went flying out the door and to x charity the next morning. I now have several thank you cards from that charity (the feel-good factor) as they were v appreciative of the stuff and several items were almost fought after in their shops but some lucky person basically went in and found their wedding (top table arrangement, small arrangements, posies, bouquets, buttonholes, bridesmaids dresses, shoes, headpieces, page boy suits) as the originally intended wearers have now grown and not an option to use - (my wedding is on hold indefinitely due to circumstances we both find ourselves in but we are still together although live apart)
Best of luck
