Yes, you can sell part of your property in any state, but it is not a normal real estate transaction. Before any sale can close, you have to go through a lot split (sometimes called a minor subdivision) to carve out a new, legally recognized parcel. That means local government approval, a professional survey, likely cooperation from your mortgage lender, and a tax bill on the gain. Done right, it is a routine process. Started without checking the right things first, it can waste thousands of dollars before you ever reach a buyer.
Check These Three Things First
Three issues can stop a lot split before it begins, and all three can be investigated cheaply.
The first is deed restrictions, also called restrictive covenants. These are conditions written into the property’s chain of title that may prohibit subdivision outright or impose minimum lot sizes larger than what local zoning allows. They can date back decades and remain enforceable even when they don’t show up in your current deed. A title search through the full chain of title is the only reliable way to find them.
The second is your homeowners association, if you have one. HOA covenants and bylaws can independently restrict or forbid dividing lots regardless of what zoning permits.
The third is your mortgage. Federal law recognizes a due-on-sale clause as a provision allowing a lender to demand full repayment if “all or any part of the property” is sold or transferred without prior written consent.1Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions The federal exceptions that protect certain transfers, like moving the property into a living trust or to a spouse, don’t cover selling a subdivided piece to an outside buyer. If there’s a mortgage on the property, you need the lender’s cooperation.
Getting Your Lender to Release Part of the Property
A mortgage is a lien against the entire property. Selling a piece of it shrinks the lender’s collateral, so no lender is obligated to agree. What you have to ask for is called a partial release, and lenders evaluate these case by case.
Fannie Mae’s servicing guidelines give a sense of how strict the conditions can be. The loan generally must be current and seasoned, with a clean recent payment history. If the loan-to-value ratio after the split would stay below 60 percent, the servicer can approve the release. If it would be 60 percent or higher, the borrower has to pay down the loan balance enough to keep the LTV at the pre-split level or at 60 percent, whichever is higher.2Fannie Mae. Evaluating a Request for the Release, or Partial Release, of Property Securing a Mortgage Loan A new appraisal is usually required.
Not every lender follows Fannie Mae’s framework, and some will simply decline. If yours does, you’re left with paying off the mortgage, refinancing, or dropping the project. Sort this out before you spend money on surveys and application fees.
Zoning and Subdivision Approval
Local government controls how land can be divided, through two separate sets of rules: zoning ordinances and subdivision regulations. Both are administered by your city or county planning and zoning department, which is where you should start once your deed and mortgage situation are clear.
Zoning sets the minimums each new parcel has to meet. The common ones are minimum lot size (in square feet or acres), minimum road frontage so the parcel has street access, and setback distances dictating how far structures must sit from new property lines. If your proposed split would create a parcel that violates any of these, you need a variance, which is a separate approval with no guaranteed outcome.
Subdivision regulations govern the mechanics of the division. They define what counts as a subdivision, what documents you file, and what infrastructure the new parcel must have. Many jurisdictions require new parcels to connect to public water and sewer, and the planning commission can condition approval on the owner installing sidewalks, curbing, stormwater drainage, or utility connections.
Surveys, Easements, and Infrastructure Costs
Every lot split application rests on a professional land survey. A licensed surveyor establishes the exact boundaries of the proposed new parcel and produces a plat map with dimensions, acreage, and a legal description. Costs vary with parcel size, terrain, and local pricing, from several hundred to several thousand dollars, and more for complex sites.
If the new parcel doesn’t front a road, you’ll need to create a permanent access easement across the land you’re keeping. An easement is a legal right allowing someone to cross or use another person’s property for a defined purpose. Easements are also needed when utility lines, water pipes, or sewer connections have to cross your retained land to reach the new lot. Draft these carefully, because once recorded they run with the land and bind every future owner.
Infrastructure obligations often go beyond what the original property needed. The new lot may require its own water and sewer connections, with hookup fees and installation costs that can be substantial. Where municipal sewer isn’t available, the new lot needs a septic system, which means the soil has to pass a percolation test or the more detailed soil and site evaluation many jurisdictions now require. If the soil can’t support a septic system with the required backup drain field, the lot may be unbuildable and the application will be denied. Stormwater management is another common requirement, sometimes triggering a drainage study and physical improvements like retention basins or grading changes before approval.
How the Approval Process Works
You file a formal plat application with the local planning commission or zoning board. The package usually includes the application form, multiple copies of the plat map, and a fee ranging from a few hundred to several thousand dollars depending on the jurisdiction.
Staff reviews the submission for compliance with every applicable ordinance. Most jurisdictions then schedule a public hearing where the planning commission considers staff recommendations, hears public comment, and votes. Approval may come with conditions you have to meet before the plat can be recorded, like installing a driveway or completing utility connections. A denial will specify which requirements weren’t met, and you can usually appeal or revise and reapply.
From the first survey to a recorded plat, the process commonly takes several months. Backlogs or complex projects can push it longer. If you already have a buyer, build that timeline into the purchase agreement.
Taxes When You Sell Part of Your Land
The tax side is where sellers most often get caught off guard. Selling a subdivided parcel is a sale of property for IRS purposes and triggers capital gains tax. Your gain is the difference between the sale price and your allocated cost basis for that specific parcel.3Office of the Law Revision Counsel. 26 USC 1001 – Determination of Amount of and Recognition of Gain or Loss
Splitting Your Cost Basis
Because you’re selling only part of what you originally bought, you have to divide your total cost basis between the parcel sold and the land kept. The IRS formula multiplies your total cost in the tract by a fraction: the fair market value of the lot being sold over the fair market value of the entire tract.4Internal Revenue Service. Publication 551 (12/2025), Basis of Assets If you paid $200,000 for the property and the parcel you’re selling represents 30 percent of total fair market value, your basis in that parcel is $60,000. Sell it for $100,000 and your taxable gain is $40,000.
Getting the allocation right matters because you can’t fix it later. If you use the wrong basis on a sale in a prior year, the IRS won’t let you correct it once the statute of limitations (generally three years) has run.4Internal Revenue Service. Publication 551 (12/2025), Basis of Assets A professional appraisal at the time of the split that values both the sold parcel and the retained land is the best support for your numbers if you’re audited.
Capital Gains Rates
If you’ve owned the property for more than a year, the gain qualifies for long-term capital gains rates, which for 2026 are 0 percent, 15 percent, or 20 percent depending on your taxable income. Most sellers land in the 15 percent bracket. Held for a year or less, the gain is taxed as ordinary income at your regular rate.
The Home Sale Exclusion Usually Won’t Save You
If the land is part of your primary residence, the Section 121 exclusion can in principle shelter up to $250,000 of gain, or $500,000 for married couples filing jointly.5Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence But selling a vacant lot apart from the house comes with strict conditions. The land must be adjacent to your dwelling, you must have owned and used it as part of your principal residence, and you must sell the dwelling itself within two years before or after the land sale in a transaction that also qualifies under Section 121.6eCFR. 26 CFR 1.121-1 – Exclusion of Gain From Sale or Exchange of a Principal Residence
That last requirement is the problem for most people. If you plan to keep living in your house and only sell a side lot, the exclusion does not apply. The gain is fully taxable. The exclusion only works when you’re also selling the home within that two-year window, and the combined exclusion across the house and land sales is capped at $250,000 or $500,000 total, not per transaction.7Internal Revenue Service. Publication 523 (2025), Selling Your Home
Closing the Sale and Recording the Split
Once the planning commission approves the split, the rest looks more like a conventional closing. A new deed is prepared for the parcel being sold, with the precise legal description from the approved plat. You and the buyer sign a purchase agreement covering price, contingencies, and closing terms. The buyer will typically order a title search on the new parcel to confirm clear ownership and check for liens.
Recording order matters at closing. The approved plat map is recorded with the county recorder of deeds first, which is what gives the new lot legal existence. Immediately after, the deed transferring the parcel to the buyer is recorded. The deed references a legal description that doesn’t exist in public records until the plat is filed, so the sequence has to run plat first, then deed. Once both are recorded, the new boundaries and ownership change become part of the public record and the sale is complete.
