Unfortunately we do not do any type of awnings. What i would do is call the HOA and ask them what they allow back there. 

I second the suggestion for the Eze Breeze panels. Great product and our clients love them! Here are a few pictures of a nice porch we completed a few years ago using this product.

That is a great questions, you have several options.

First, I usually recommended allowing the deck to weather for a few months.  This gets rid of some of the surface chemicals used in pressure treating lumber thereby allowing a better adhesion of your deck paint or stain.  If you do not want to wait you can power wash the deck but we have had less success with this option as it sometimes ends up “splotchy”. 

Next, there are many great products on the market, our company uses Sherwin Williams “Super Deck” but other painting companies have great products as well.  I would stay with a better known company such as Sherwin Williams or Benjamin Moore.  In my experience the quality is definitely better.

Finally, realize that you will need to remain proactive with your deck.  Inspect it every year to see how it is holding up and whether you need to make repairs or reapply your stain.  We have found that stains last about 2 years and deck paints 2-3 years despite what the manufacturer states.

I hope this helps
