Selling single family homes and vacant land often times involves getting a land survey. Some owners have survey documents from their purchase of a home, which the new buyer might choose to accept, especially if it seems clear the boundaries haven't changed since the current seller took possession of the property. That will save the seller the cost of having a new survey done and maybe help the buyer get a slightly better price. If significant changes have been made to the property or the survey is old the buyer might insist on a new survey.
How old is "old"? If there hasn't been a survey in decades, it's time for a new one. Even if the perimeter of the lot looks the same as it did before, the land may have shifted. Measurement tools used by surveyors have improved and what was once considered a de minimis encroachment with new measurements might be actually greater than six inches, or vice-versa.
If you have your original survey, the company that performed it will usually give a discount if you contact them for a new survey of the same property.
Here are some survey companies we've worked with on Oahu for residential properties:
There have been changes in the surveyor scene in the past couple of years. I called surveyors recently and found that two had gone out of business. They are:
DJNS Surveying & Mapping Inc - Dennis retired on 4/30/2016
Po Box 25636
Honolulu, HI 96825
Melvin Masuda - retired and sold his business to Gavin Hirano (see above)
Wes Tengan has been around for a long time and is well respected. With DJNS and Mel Masuda now retired, Wes might be busier than in the past. Plan your surveys accordingly. Wes might not have time in his schedule for a last-minute rush job!
