As the housing situation is only going to get worse why don't local governments and councils allow more static caravan sites become residential?.
I know many people that would love to live in there static caravans but are not allowed because they must nit use it as a postal address, many retired couples already are as good as living in them 10 months of the year but have to return home as most sites must close for 6 weeks to 8 weeks of the year. If councils gave permission to turn them residential, then many people could sell or rent out there homes this putting many more homes on the market. All that you old then need is to make the caravan owners pay A band council tax for local services. Also councils could buy or use available land and turn them into static residential sites, better then covering them in houses. They could pre buy static caravans on a bulk deal and rent them out this helping to reduce council waiting lists, especially as most static caravans are much better accommodation than the houses they build these days, also much better than housing people in dangerous high rise flats that are highly flamible..
