What kind of fence?

There are 2 issues here - the first is the need for a fence, the second is the need to report the neighbors to the township/city for code violations (hopefully the city has one regarding the height or maintenance of lawns). As for the fence, choose one that complements your house and landscaping, don't just select one for the amount of privacy it provides, or you will be disappointed (most likely, you would need a tall, stockade-style to totally block the view, and that would detract from your beautiful yard. Before you install the fence, see if you can get the contractor to give you a visualization of the completed project before you break ground, so you can change your mind if you have to.

You need one that fits into your outside décor. Drive around the area and see what others have and if you would like copy. You need also to check out the regulations of the location before you even think about construction as you may also need a permit from your municipality. They usually have height restrictions also. It all depends on how much you want to spend. A good solid fence would stop the weeds from seeding your property, but would also block your view. Go to a hardware store that sells lumber since they usually have pamphlets with various types of fencing plans and formations. Once you have a plan go to a couple of stores to get an estimate for materials.

Check your municipality for height restrictions. Typically anything over 3' requires proper footings and a permit. Before you build, call the city surveyor out to double check property line and adequate placement for the proposed fence. You do not want to get into a neighbor dispute as to whose property it is on. Decide what type of fence compliments your home and neighborhood. Then start interviewing contractors to build.

If you talked to the neighbor and the town and neither will do anything your only recourse is a fence. You need the check with your town if you are allowed to put one up, height restrictions, permits, and inspections. Also make sure the fence is on your property not the neighbors. BTW, you cannot sue your neighbor if you get weeds. Hard to prove where they came from.

You should let the town handle this if they have blight regulations. Have them talk to him give him an ultimatum or site and fine him. If they have no rules regarding blight or a Blight Officer then he has the right to do as he pleases with and on his property. You may not like his weeds, but they are his. Wind blows/carries pollen and seeds. No way to tell if they are from his property or miles away. I can't see any judge taking a case regarding weeds on someone else's property. And to what gain.

Here in LA you couldn't get an attorney to take such a "nuisance" case and any Judge, if it actually made it to a courtroom would scold counsel for taking on such a case and waste the Courts time and resources. A small country lawyer might take just because they are bored and have nothing to do. Just for giggles, if this actually did make the books, it would be hilarious to watch the attorneys argue the case.

There is always "Small Claims Court". No lawyers necessary, you each argue your own case. You could provide pictures, statements from other homeowners on your street, and a Realtor's assessment that compares the value of your home based on others of the same size and condition as yours who do not have a house next to them with a crappy yard ( your home value could be negatively impacted by the condition of your neighbors yard). You should be able to enjoy your yard and entertain friends and family without an eyesore next door. Have estimates ready for the cost of building a fence. Then it's up to the judge after hearing both sides.It could be worse, it could be filled with junk cars and trash. You might not win, but you just might and be able to pay for a fence. Good luck.
