[quote=CVnewbie]We then called the HOA and asked when do we need to get an approval. They said anything that is visible from the Common Area will need an approval. Our backyard is not visible from the street or common area. The only one who can see it is our next door neighbor.

If this is indeed the case then stand firm. Write to the HOA and let them know that you’re not violating the rules and that if they believe otherwise then they’re welcome to come out to your home and explain/point out exactly what and how the playhouse violate the CC&Rs.

The way I have always dealt with HOA is by shifting the burden of proof to them.
