Sometimes the best way to make a small or awkward lot work is to buy the one next to it. Combining parcels is often called assemblage.
Why Buyers Combine Lots
Two lots together may meet minimum area and frontage requirements that neither meets alone. A larger combined site may also allow better placement of a house, septic system, and well, with more room for setbacks.
Check Zoning First
Read the zoning schedule for the district and compare it with the combined dimensions. Also ask the municipality how it treats adjoining lots held in common ownership, since some towns treat them as merged for zoning purposes.
Merger and Its Effects
Merger can be helpful or limiting. It may make a building plan possible, but it can also remove the option of selling the lots separately later. Discuss your goals with your attorney before closing.
Taxes and Title
Combined lots may be reassessed, and the legal description and tax map may need updating. A title search on each lot will show whether the same owner holds both and whether easements or liens affect either.
Timing the Purchases
If the lots have different owners, coordinate contracts so that one purchase does not leave you holding a lot you cannot use. Contingencies tied to the second purchase can help, and your attorney can draft them.
