If you can’t find any records online, you’ll need to contact your county clerk’s office to do further research. They should have property records on file, or can at least point you in the right direction of who to contact. You can also speak with your neighbors about when their houses were built because they were likely built around the same time.

Measure from zero on a measuring tape by placing the metal hook right up against the edge of what you need to measure. You can also latch the hook onto an open edge—of, say, a table—to accurately measure as well. If you begin at the 1-inch mark, you'll need to subtract an inch from your total.

With proper training and experience, reading blueprints is fairly straightforward and not very difficult. If you don’t have the necessary knowledge to interpret the symbols, abbreviations, and other notations used, blueprints may not make sense. Learning to read blueprints can help you understand the construction process and keep you more involved and informed when you’re building a house.

If you or your mortgage lender think your land survey needs to be more accurate, double-check the survey report and get at least a second opinion from the original surveyor and an inspector, if possible. Although it’s unlikely, even reputable surveying companies can make mistakes. An inaccurate survey can cause problems down the road in the case of any property line disputes, so it’s best to resolve any inaccuracies as quickly as possible.
