You buy a corner building downtown. The plan is a loading area out back plus four parking spaces. Then title work turns up a sixteen foot alley running through your site, dedicated on a plat from 1912, and nobody has driven it since the Truman administration. Land surveying records are how you learn whether that alley is a ghost or a live obstacle.

Grass growing over an alley proves nothing. Only the record closes the question.

That Strip Behind the Building Has a Paper Trail

Old alleys exist because old plats put them there. Someone subdividing a block in 1905 drew a service lane behind the lots, then dedicated it to public use.

Cities accepted many of those dedications and never built a thing. The alley lives on paper while the physical world grows fences, sheds and parking over it. Everyone forgets, including the city.

The paper doesn’t forget. It sits in the record until you apply for a permit.

The Records That Answer the Question

Four sets of documents carry most of the answer. Pull all of them, because any single one will mislead you.

The original subdivision plat

Start here. The plat shows the alley’s width, its location and the dedication language itself.

That language matters more than the drawing. Some plats dedicate the alley to the public, and others create a private easement for the lot owners only. Those two paths lead to different outcomes, and people conflate them constantly.

The chain of deeds

Every deed describes what got conveyed and what got reserved. Read them in order rather than reading only the current one.

Older deeds sometimes reference the alley directly, granting or reserving rights that survive today. Your own deed may say nothing about it, which people misread as good news.

The vacation ordinance

If the city gave up the alley, an ordinance or resolution usually says so. That document is the most valuable paper in the whole search.

Find out whether it was ever recorded in the land records. Plenty of vacations happened at a council meeting and never reached the recorder’s office, so the title search misses them. Local practice decides where to look.

Prior surveys and right-of-way maps

Somebody has surveyed this block before. Old surveys, city right-of-way maps and utility records all carry evidence about what was opened, used and abandoned. They also point to monuments that may still sit in the ground.

Vacated Doesn’t Mean Yours, and It Doesn’t Mean Clear

Owners hear “the alley was vacated” and assume the land became theirs, free and clear. Both halves of that break regularly.

When a public alley gets vacated, title generally reverts to the abutting owners, often splitting at the centerline. State law drives that rule and the vacation terms can change it, so confirm yours. You may own half the strip while your neighbor owns the rest.

The bigger trap is what the vacation kept. These ordinances commonly reserve a utility easement across the same ground. The road goes away, and the sewer main under it does not. You own the dirt, you can’t build on it, and your loading dock sits on a live main.

Your deed may stay silent about the strip even though you own it, since reversion often happens by operation of law rather than by a new deed. Silence proves nothing either way.

Shared Driveways Are Their Own Mess

Old blocks are full of driveways serving two buildings. Sometimes a recorded reciprocal easement created that. Sometimes two neighbors in 1948 just started sharing.

The first case is manageable, since a document exists and says who can do what. The second is where prescriptive claims live, and those turn on state law and decades of facts. A shared driveway with no recorded instrument behind it is a legal question, so hire an attorney rather than asking a surveyor for an opinion.

What to Pull Before You Design

Get this in hand before schematic design. Late discovery is what makes these problems expensive.

• The original recorded plat, including full dedication language
• Every deed in the chain, read in order
• Any vacation ordinance, plus proof of whether it was recorded
• Utility easements reserved in that vacation
• Prior surveys of your parcel and the adjoining ones
• City right-of-way maps and alley opening records
• Utility company records for lines in the strip

Hand the stack to your surveyor and ask for the alley plotted onto your parcel. Seeing the strip on a picture of your site turns an abstract problem into an obvious one.

When the Records Run Out

Old records have holes. Courthouse fires, sloppy indexing, plats referencing monuments that rotted a century ago. Sometimes the answer isn’t there.

Then you’re choosing between a quiet title action, a negotiated agreement, or a design that avoids the strip entirely. Attorneys handle the first two. The third is often fastest and cheapest, and fighting for eight feet of alley can easily cost more than the eight feet is worth.

Frequently Asked Questions

How do I find out if an alley behind my property was vacated?

Start with the city clerk or public works, since vacations happen by ordinance at the local level. Then check the county land records for a recorded instrument reflecting that action. The two sources disagree more often than you’d expect, because many vacations never got recorded. A surveyor or title professional who works in your area knows which office holds the answer.

If the alley was vacated, do I own all of it?

Usually not, since reversion commonly splits the strip at the centerline between abutting owners. State law controls that outcome and the vacation terms can modify it, so confirm the rule that applies to you. Your deed may not mention the strip even though you own part of it. Ask your surveyor to plot the reverted area and an attorney to confirm the split.

Can I build over a vacated alley?

Owning the ground and being allowed to build on it are separate questions. Most vacation ordinances reserve easements for utilities, and those reservations survive and follow the land. A reserved easement usually blocks permanent structures, though pavement and parking are sometimes acceptable. Read the exact language, then confirm with every utility that has lines there.

What if a neighbor has used the alley for decades?

Long use can create rights under some state doctrines, and the requirements vary enormously. Records will show whether a written easement exists, which is the easy scenario. Absent a document, you’re in legal territory rather than survey territory. Bring in a real estate attorney early, since these claims get harder to resolve the longer they sit.

Is a title search enough, or do I need survey records too?

A title search reports what’s recorded, and a survey shows how those records land on the ground. Neither covers the other, and old alleys sit exactly in the gap. The dedication may be recorded while the physical strip has been fenced into somebody’s yard for forty years. Order both, then have the surveyor plot the record onto the parcel.
