Legally speaking? No. But maybe the owner is nice? Talk to the owner.

In order for you to claim adverse possession, you would have to have maintained it for at least 15 years. You should confer with a lawyer regarding whether you meet the requirements of the statute. Since your question indicates 14 years, you may not have achieved this. The owner might be interested in selling it to you for a reasonable price since it is small. You might also check your local zoning ordinance and check to see whether the lot is buildable. There are usually set back requirements for any building. If the lot is too small, it may not be possible to build on the lot without getting variances. That will affect the value of the land. You should take that into consideration too.
