How a Plat of Survey Helps Spot Problems Before a Permit Review

You draw up the addition. The design looks clean. You file for the permit, and the reviewer sends it back over a setback you never saw. That delay stings, and a plat of survey would have caught it first. A plat of survey is the drawing that shows your lot’s real lines, dimensions and features on one page. For developers building in Montgomery, that page is an early warning system. Check the plat before you design, and you fix problems on paper instead of at the permit counter.

Setback Conflicts Hidden in an Otherwise Buildable Lot

A lot can look wide open and still fail on setbacks. Setbacks are the required gaps between your building and the property lines. The city sets them by zone, and they apply to additions, garages, decks and sheds. A plat shows your lines and dimensions, so you can measure the real buildable area.

Picture a back addition that fits the yard with room to spare. The rear setback might still cut into your plan by two feet. That gap kills the design as drawn. The plat lets you catch that conflict during design. You shrink the footprint or shift the location before a reviewer ever sees it.

Recorded Easements That Restrict the Proposed Building Area

An easement can block the exact spot where you want to build. It’s a recorded right that lets someone else use part of your land. The plat shows where these run, so you plan around them instead of into them. Several types show up on a typical lot:

• Utility easements for power, water and sewer lines
• Drainage easements that carry storm runoff
• Access easements that give a neighbor a path
• Shared driveway or parking rights

Build a garage over a utility easement and the reviewer stops you cold. The utility can also force you to tear it out later. The plat marks these strips clearly. You keep your new structure off them from the start.

Existing Improvements Positioned Too Close to Property Lines

The stuff already on your lot can cause permit problems too. A plat shows where your fences, sheds, driveways and structures actually sit. Sometimes those features sit right on a line, or across it. That’s an encroachment, and it can surface during review.

Maybe an old shed crosses onto the neighbor’s land. Maybe the driveway hugs the line with no clearance. These issues can stall a permit for new work nearby. Seeing them on the plat gives you time to plan a fix. You move the feature, correct the record or sort out an agreement before you file.

Lot Dimensions That Differ From Early Design Assumptions

Many site plans start with the wrong numbers. Designers pull dimensions from tax maps, old deeds or a quick tape measure in the yard. Those sources miss the mark often. A tax map is for assessing value, not for building.

A plat of survey gives you the true boundary dimensions, measured in the field. The real lot may run shorter or narrower than the early design assumed. Even a few feet changes what fits. Start the design on survey numbers and your plan matches the ground. Start on a guess and you redraw everything after the survey shows up.

Survey Details That Can Reduce Permit Plan Revisions

Every constraint you catch early is a revision you skip later. The plat puts setbacks, easements, existing features and true dimensions on one drawing. Your architect and contractor design around real limits from day one.

Set the order right. Get the plat first, then share it with the whole team before anyone finalizes the plan. Confirm the zoning setbacks for your parcel with the City of Montgomery. Line the design up against the plat, then file a set that already clears the obvious hurdles. Fewer surprises at review means fewer rounds of corrections. Your permit moves faster because the problems got solved before submission.

Frequently Asked Questions

What is a plat of survey?

It’s a scaled drawing of your lot that shows the boundary lines, dimensions, easements and existing improvements. A licensed surveyor measures the property and prepares it. Builders and owners use it to plan work and to check a design against real site limits.

How does a plat of survey help before a permit review?

It reveals setback conflicts, recorded easements, encroachments and true lot dimensions before you file. Catching those on the drawing lets you adjust the design early. That means fewer rejected plans and fewer rounds of corrections at the permit office.

Is a plat of survey the same as a tax map?

No. A tax map helps the county assess property value and shows only rough boundaries. A plat of survey comes from field measurements and shows exact dimensions and features. You should design and permit from the survey, not the tax map.

Will a plat show easements on my property?

It shows recorded easements that affect the lot, like utility, drainage and access rights. Those strips can block where you build. The surveyor plots them so you can keep new structures clear of them and avoid a permit holdup.

When should I get a plat of survey for a project in Montgomery?

Get it before design, not after. Early survey data lets your team plan around setbacks and easements from the start. Waiting until after you draw the plans often means redoing them once the real dimensions come in.
