I installed a privacy fence two years ago. I discussed the property line with my neighbor. Using their garage as the property line. They agreed to the fence being installed. I put the fence a foot from the garage. Our garages are (approximately 8 feet apart) the neighbor agreed I could put a flower bed between the garages, since I always maintained this area. In preparing the area I removed a lot of creek rock and dug a foot deep. Now two years later they had a surveyor find the property pins. One of the pins is between the garages. (I never found any surveyor pins during the preparation for the flower bed.) The pin at the front of my property is not in alignment with the pin between the garages. I installed the fence in alignment with the front pin. I can not see the pins only the surveyors caps. The surveyor plates from 1909 show the property is 55 ft wide front and back. The caps from the surveyor show it at an angle going inward on my property. Making my fence approximately 5 inches on their property. They have now decided to install their own privacy fence one foot from my fence going by the front pin. (Their garage would be the property line.) I discussed having two fences back to back would be a safety issue for kids and animals. If I remove my fence can I still use the land (one foot) that was going to be between the fences? Or should I still try and find the 1909 surveyor pins? Problem solved if they are in a different location than the caps the surveyor has installed. No codes or regulations for fences in my area.
