That Little Drawing of Your Lot: What Is a House Location Survey?

A Blueprint for Peace of Mind (For Your Lender)

Here’s the small mystery at the heart of the house location survey: while you, the buyer, pay for it, it isn’t primarily for you. It’s for your lender and your title insurance company. Think of it as a crucial check-up before a massive investment is made. A lender is about to extend you a loan for, say, $650,000 to buy a home in Arlington. Your title insurer is about to issue a policy guaranteeing that you have clear, legal ownership of that home. Before they commit, they need to see with their own eyes—or rather, the surveyor’s eyes—that the physical property matches the legal paperwork.

They need to know that the beautiful four-bedroom colonial you’re buying is actually located fully within the property boundaries described in the deed. They need to know its brand-new deck doesn’t accidentally overhang the neighbor’s yard, a problem we call an encroachment. They need to know the detached garage wasn’t built over a buried utility line, violating a recorded easement (a right for someone else, like a utility company, to use a portion of your property).

These potential issues represent risks. An encroachment could lead to a lawsuit, legal fees, and even a court order to tear down the offending structure. That would diminish the value of the property, which serves as the collateral for the lender’s loan. The survey is their tool for managing that risk. It’s a snapshot that assures them the asset they are financing is physically sound and free of major boundary conflicts.

What the Surveyor’s Drawing Actually Shows

When you see the survey, you’ll get a one-page, top-down drawing. It’s a simple diagram, not a fancy 3D rendering. On it, a licensed surveyor will plat, or map out, several key things:

• The property lines, as taken from the legal description in the land records.
• The location of the house and other significant structures on the property, like a garage, a shed, or a pool.
• Major improvements like the driveway, walkways, patios, and decks.
• Visible fences and evidence of any easements (like utility boxes or manhole covers).

The drawing will clearly show the relationship between all these elements and the property lines. It will note, for instance, that the house is 15 feet from the front line and 10 feet from the side line. More importantly, it will flag any encroachments—your fence being two feet onto the neighbor's property, or the neighbor's driveway crossing a corner of yours.

It’s important to understand what a house location survey is not. It is not a Boundary Survey. A boundary survey is a much more detailed and expensive process where a surveyor physically locates or sets metal pins or concrete monuments at the precise corners of your property. That’s what you would order if you were planning to build a fence and needed to know the exact line. The house location survey is simply a picture of what’s already there for insurance purposes.

Navigating the Requirement in D.C., Maryland, and Virginia

So, when is this document actually required? The answer is fairly consistent across the DMV, because it’s driven by lenders, not local law.

Generally, if you are getting a mortgage to purchase a single-family detached home, a duplex, or a townhouse, your lender will require a new house location survey. It’s a standard condition of the loan.

The most common exception is a condominium purchase. When you buy a condo in Dupont Circle or a high-rise in Bethesda, you are primarily buying the airspace within your unit’s walls, along with a shared interest in the common areas. The boundaries of your ownership are defined by the condominium plat filed when the building was created, so a separate survey for your individual unit isn’t necessary for the lender.

What if you’re a cash buyer? With no lender, there is no one to *require* you to get a survey. However, waiving it is a significant risk. If you skip the survey, you are personally accepting the financial and legal liability for any boundary disputes, encroachments, or other issues that a survey would have uncovered. Furthermore, your owner’s title insurance policy will likely take an exception for these matters, meaning it would not cover you for claims related to problems a survey would have revealed. For this reason, we almost always encourage cash buyers to invest in a survey for their own due diligence and peace of mind.

The process is simple. Your title company—that’s us—will order the survey on your behalf from a trusted, licensed surveyor. The cost, which can often range from $450 to $750 for a typical lot in the DMV, will appear as a line item on your Closing Disclosure. It’s a small price for a great deal of clarity.

A Final Thought

The journey to homeownership is full of abstract documents—deeds, notes, policies. The house location survey is different. It’s a bridge between the legal language of ownership and the physical reality of home. It takes the words written in a county courthouse and translates them into the space where you will plant a garden, watch your children play, and build a life. It confirms that the place you’ve fallen in love with is, in fact, the place you are about to own.
