Best of luck to you, love your community
at hand.... If you do not live in a subdivision with a Home Owners Association contact the building commissioner of your town, they will be able to tell you exactly what you can and cannot do, you then have
to provide them with a plan and present them for acceptance....
Each town has its own rules and sometimes they are different for different properties, i.e. how far away from the next property, how close to the home, to the alley way etc.
So careful double check, and if you are the buyer, same here do not buy the property thinking you can do this that and something else, get the information from the right source first and your Realtor who is helping you
to find your property will be of assistance where to check.... and make sure you know exactly what you need.

I'm fairly familiar with Treyburn, and would suggest he following site to you http://www.treyburnhomeowners.com
there are a number of links to HOA specific documents. Fences are allowed, but there may be different requirements affecting the different sections within Treyburn. Outbuildings are allowed (again you would need to seek approval from the HOA) but could be limited by the size of the lot you're consdiering. I'm unclear if you're looking at one of the large lots at Treyburn Pointe for example and having a home built or if you're looking at a resale home somewhere else within Treyburn.
Based on my clients experiences I consider Treyburn's HOA relatively easy to work with, and you'll always get more being nice than starting off confrontational.
If I can be of any further assistance to you, feel free to contact me through my perrsonal profile here on Trulia.
Good Luck and Happy House Hunting!
My recommendation is that if your unsatisfied, keep trying to collaborate and coordinate with the community leaders. It can get expenisive if you don't. Take it from someone who learned the hard way.
You can find the answers to your question at http://www.treyburnhomeowners.com, there are links to the information there as well as contact numbers for the Home owners assoc.
