Himy neighbor contacted me with his plans to replace fence , however there is no issues with the fence common to my and his home, and I don't see any reason to spend unnecessary 3k to replace something which has no issue. there might be issues with his other side of fence, I have no idea, as his house is behind mine.how would you handle the situation ?

Those won't be easy to remove later, if you decide to install a different type of fence.

What kind of fence or security is recommended?

I am looking at $18.95 and add on Criminal/ sex offence ( $4) .

The city employees pick the sign up, then charge a littering offence for each sign to cover their costs---and the signs have the handy dandy phone number of who to site on them!

My husband thinks using the persons name in the business name is tacky (no offence, he's not in rei)

Usually a big difference in terms of what type of fence can be installed in the front of the home as compared to rear.

More states are promoting housing stability by removing no-cause evictions and obligating landlords to continue renting to tenants unless landlord can prove an egregious and evictable offence.

What kind of fence material are you going with? 

If not.. absolutely  no offence taken.
