Usually yes, through a local process often called a lot combination, lot consolidation or replat [1].
Why people combine lots:
- to build across the old line (a garage or addition that would otherwise break setback rules),
- to simplify taxes and records,
- to remove an interior lot line.
Things to consider:
- Approval: some places need only a recorded deed or form. Others need a new survey and a replat.
- Taxes and fees: the change in assessed value and recording costs.
- Mortgages: if each lot has a different lender, the combination can be more complicated.
- Selling later: separating them again may need a new approval.
Ask your county or city planning office what they need. A licensed surveyor can prepare the new legal description and plat if required [1].
