Many fences are not installed on the property line. Many clients believe that the fence marks the property line. In the past, the placement of the fences was generally done based on an informal agreement between two neighbors without doing a land survey. Part of the fence may be on the line, but it could also be off by 3 inches - 1 foot more cutting into your property and, more seriously, could extend into your neighbor’s property which constitutes an encroachment.
TKM Land Surveyors LP recommends that you do a land survey before you install a fence to avoid time consuming and costly mistakes if the fence encroaches on the neighbor’s property. If your neighbor is installing a fence that you believe may be encroaching on your property, TKM Land Surveyors LP recommends you do a survey as well. If the neighbor says that they have done a survey, then you should ask to receive a copy of the survey. In the event of a variance between your neighbor's survey and the survey done by TKM Land Surveyors LP, then the next step is for both land surveyors to review their methodology and findings to determine the cause of the variance.
If you want to install a fence on two or more sides, then a boundary survey would be appropriate. A boundary/property/lot line survey would generally be recommended if you plan to install a fence on one side. Having said that, it is always good to know where your boundary lines are located as well as the total square footage of the lot to protect your property investment. For both types of surveys, TKM Land Surveyors LP is required to set durable markers at the corners as well as submit the survey to be County for review and filing.
TKM Land Surveyors LP recommends setting wooden stakes along the property lines for larger properties, or properties where there are a number of property elements (trees, fence, landscaping) that might make it difficult to create a physical property line by typing string from one durable marker to the other.
