The laws here are somewhat strange, You can be nude in your own yard providing no one can see you or you dont cause alarm in doing so. In other words you cant ne nude!!
I have been a practicing nudist for the major part of my life , I live a nudist lifestyle when at home ,both indoors and out.
I live in an area that affords me to do so,having a rather large piece of property and I am the only house on the street,however I did erect a 7 ft fence around the perimiter of my property so as not to cause problems with paserbys.
I have an outdoor shower,Hot tub and a large deck for nude tanning, I am able to moe my lawn,wash my truck and bbq all nude.
As I said earlier the laws are strange here in the U.S But as long as you mind your own buisnes and dont cause an issue I hav never had any problems at all.

I'm not sure about the legality of it but when we had a private back yard, we sunned in the back yard all the time. Our patio table was where we ate a lot of meals and if the weather permitted, we were typically nude all the time. Here's hoping you can enjoy your back yard in your own way as well.
