Community Problem Regarding Maintenance

I wondered if somebody could help iwth advice on the following comunity problem

I own  first floor apartment in a block on 4 on an urbanisation with an established community and am required to re-paint the property externally by the end of May but in order to achieve this I have to gain access to the garden below for the setup of ladders and masking off

I wrote to the administrator requests this access and was decllined advising me that I would need to find some other way to paint the walls which isn´t possible.

The property below, is managed by the President of the community, a person that I have had disagreements with in the past and that introduced the requirement to paint all properties by a certain date

I believe that there is a clause in the Horizontial Property Law that requires owners to provide access for maintenance so can anybody please clafify this

My lawyer says denounce them but tis seems a bit silly,especially as they are The President of the community 

yet another case of a president letting the power go to his head!! Thats one thing I hate about all this community crap. We had the same thing on our urb. So at the next AGM, we outed both the president and the vice presisent and voted in a much better pair.

Hope you get it sorted.

Strangely that is exactly what the lawyer has come back with which has been sent to the administrator and president and I await their response

Thank you
