Where to get plot plan

[Aries Li]

Hello my friends,

I'd like to install a fence ourselves on the back yard. I checked the city code that privacy fence on back yard doesn't need a permit.

However, our HOA requires us to submit a request along with the plot plan.

I am fine with that but I couldn't find the any plot plan in the closing documents. 

Who would be able to provide or find the plot plan? I understand a contractor might do it, but we prefer to DIY. Thanks a lot.
