The first step is to contact your local building department. They will be able to tell you if the house was built over the property line and what steps you need to take to resolve the issue.
2. Contact a real estate attorney.
If the house is indeed built over the property line, you may need to contact a real estate attorney to help you resolve the issue. An attorney can help you negotiate with the homeowner or take legal action if necessary.
3. Contact the homeowner.
If you are comfortable doing so, you can also try contacting the homeowner yourself to discuss the issue. Be polite and respectful, and explain that you are concerned about the house being built over the property line.
4. Get a survey of your property.
If you are not sure whether or not the house is built over the property line, you may want to get a survey of your property. A survey can show you the exact location of your property line and help you determine if the house is encroaching on your property.
5. Consider mediation.
If you are unable to resolve the issue with the homeowner, you may want to consider mediation. Mediation is a process in which a neutral third party helps you and the homeowner reach a resolution.
6. Take legal action.
If all else fails, you may need to take legal action to resolve the issue. This can be a costly and time-consuming process, but it may be necessary to protect your property rights.
