Can I get a survey drawing of my property from the city or county?
Some cities — not all — keep survey drawings on file when a house or building is constructed. They are generally kept with the records of the Building Inspector, and indexed by the address of the property. There is less chance of there being such a drawing for an older house. These drawings vary, but usually they show the property dimensions and the distance from the house to the property lines at various points. If you can find such a drawing, it may be useful. But bear in mind that it is not new, and that there may have been changes in the house or other objects shown.
All counties keep plats on file. A plat is a map or drawing that is made and recorded when a larger piece of land is divided into lots. The process of dividing land by means of such a map or drawing is known as platting. Not all property is platted. But if your property is described as "Lot 7, Block 3, Jones Addition", or something similar, the phrase "Jones Addition" is the name of a plat that is filed at the courthouse in the county where the property is located.
Copies of plats can be obtained for a small fee from the County Recorder, and may also be available from the County Surveyor if there is one.
A plat is the official record of the location and dimensions of the lots shown on it. Newer plats give complete dimensions for all lots. Older plats may have missing or inaccurate dimensions. One type of plat, known as an Auditor's Subdivision, was not always surveyed on the ground. Plats in Minnesota may be as old as the early 1850's.
Some counties also maintain half-section maps or tax maps. These are made by combining information from plats, deeds, and other sources. They are not considered official records, and may not include complete dimensions. However, they do show all properties, whether or not they are platted. These maps, in counties where they are available, can usually be obtained from the County Assessor or County Surveyor.
In some counties, land parcel maps are prepared by private companies and combined in books. These are commonly known as "plat books", although the maps they contain are not actually plats. The books are available from the companies themselves, and are also sometimes found in public libraries. The maps generally do not include many property dimensions.
County maps and plats generally cost from $2 to $20. When ordering maps and plats, it is best to give your legal description (see Question 15) to the clerk or technician to make sure you get the right one. Some plats have multiple sheets of drawings, only one of which will show your property. Some plats also have a separate sheet with text only, rather than drawings. The name of the surveyor who prepared the plat is given in this text, along with other information.
Although a half-section map, tax map, or plat will give the dimensions of a piece of property, it does not show buildings, fences, curbs, sidewalks, or other visible objects. When using such a map, it is often hard to tell where the property lines are located on the ground. That is much easier to do with a survey drawing which shows the visible objects.
