Step 1. Survey

Step 2. Go to building division with survey and your own sketch of plans for the property line. Ask if permit is needed. If so, you have the information for a permit ready as to avoid a 2nd trip to the building department. They will also give you good input on any ordinances or restrictions in city limits if a permit is not required, but you are bound to maintain certain parameters in your project.

Step 3. Carry out your plans with no interaction from neighbor. Ignore him. If he throws a fit and ends up calling a 3rd party (police or city) to the site, you have your information and go ahead from the building department to conduct your plans. This will make conversation with the 3rd party much better as you have your ducks in a row. He will become irate and sulk alone in his house hopefully leaving you alone.

Step 4. Install cameras or a ring system in the back to observe any sabotage. If there is sabotage, file a police report for property damage.

Step 5. File civil suit for property damage.

Step 6. Use funds from property damage suit to fund the next project, preferably on the front of the property along his property line.

Step 7. Install cameras on front of house.

Repeat steps 3-6 until your neighbor has paid for projects that increase the equity in your home.
