Static caravan

Hi
I am applying for a fiance visa. My partner lives in (and owns) a static caravan on a non-residential park which closes for a few weeks each year when he goes on holiday. He pays no Council Tax as I understand the accommodation is not classed as permanent. I see nothing specific in the immigration rules about this. Would this accommodation be acceptable to UKVI?
Thanks

Please provide more detail, e.g how is it that your partner resides on a non-residential site (which seems to be a contradiction) and why doesn't he pay council tax? Also will the caravan not be overcrowded when you arrive and does it comply with public health regulations?

Read the Accommodation and Ownership/occupation sections here:

and note:

The decision maker must be satisfied that adequate permanent accommodation will be available after the marriage or the civil partnership has taken place and that adequate temporary accommodation will be available in the meantime

Thank you manci, very helpful reference.
