Waves Make sure to mention the free installation to your community! (I may limit this to a small initial number of customers, we'll see how it goes).
I have an HOA, as well. In our bylaws, we're allowed a garden of 50 square feet without explicit permission, so I didn't apply for an arch. request. But I'd be happy to help any customers apply.
