In-Ground Spa Removal - Houston

[Matthew Foucheaux]

I have a home in the Cypress, TX area that has a small in-ground spa (roughly 6'L x 3'W).  The spa has a leak and it is no longer level (sagging where the leak is).  I'd like to just back fill the thing in after punching a load of holes in the sides and bottom.  It looks to be a plastic liner on the exterior, but I have no clue what's underneath.  

Does anyone in the Houston area have thoughts or comments regarding this?  

Do I need to worry about permits?

Are there any other legal items that need to be addressed (seller's disclosure, platt, etc.)?

Any thoughts on affecting the value of the home (hot tub vs. no hot tub)?
