Alice Eve's Neighbors Fuming Over Illegal Fence

'Star Trek' actress Alice Eve is now getting the wrath of a furious neighbor who claims she illegally built a fence on city property.

The Hollywood Hills dispute is all over a 6 foot fence installed back in April at the edge of her property. Neighbors were outraged because the fence is blocking off a wildlife corridor, which is NOT part of Alice's property. One angry neighbor filed a complaint with the city.

City officials tell us the beef is legit ... the fence is on government property.

The city tells us Alice was put on notice in July for the violation, and there was a hearing on the matter in September. We're told Alice was not there. We reached out to her camp, but no word back yet.

As of Friday, the fence is still standing. The neighbor who dimed her out to the city is pissed and wants it torn down ASAP. He's clearly not a fan of her work in "She's Out of My League."

He might be alone on that one.
