You have a verity of options
1. Visit the county recorder's office or the assessor's office. Ask what maps are available for public viewing that include your neighborhood and street. Request a copy of any maps that show clear dimensions of your property lines.
2. You can also call out a land surveyor. Hire a surveyor if you do not have a survey. A surveyor is a professional who can measure and map the property lines for you. The surveyor will mark the lines at the corners with stakes. Be present when the surveyor comes to measure your property, so he can point out where the property lines are. The cost of a survey varies depending on your location, property value and lot size.
3. Check your deed. The deed contains a description of your property's measurements and boundaries in words. Measure from the landmarks in the description to the property lines. Mark each corner with a stake or other marker. Measure from each stake to the next all the way around your property to ensure the measured lines match the deed.
4.Check the official website for the assessor's office in your municipality. Some assessors have mapping tools available online for all of the real estate in the area.
