Do you need a survey when you buy a home in Miami-Dade?

Florida law does not require a survey on every residential closing, but most lenders and title companies expect one, and a current boundary survey is the main way to remove the "survey exception" from your owner's title policy. As of August 2026, a standard Miami-Dade residential lot typically runs about $300 to $800 to survey, and the buyer usually pays. For a $1M+ home, that is a small line item that can expose a fence, pool deck, addition, or easement problem before it becomes yours.

Most buyers in this price range spend their energy on the inspection, the appraisal, and the insurance quote. The survey gets treated like paperwork. I've watched it turn into the one document that changed a deal, and it almost always happens the same way: someone assumes the fence is the property line.

It usually isn't. Here's what a survey does, what it tends to find on Miami lots, and what to do with the answer.

What the survey exception really means

Your title commitment lists exceptions, which are things the policy will not cover. One standard exception covers anything an accurate survey would have shown: encroachments, boundary disputes, easements, and setback violations.

Without a survey, that exception stays in your policy. You'd own the home, but the title policy would not protect you if a neighbor's structure sits on your side of the line or your pool deck crosses an easement.

With a current survey, the title agent can narrow that exception to only what the survey actually shows. Florida Statute 627.7842 sets the framework. If a compliant survey certified to the title insurer was completed within 90 days before closing, the policy generally may except only the matters shown on that survey. The details of your commitment and any endorsements are worth walking through with your title agent, because this is a place where the paperwork matters.

What a survey tends to catch on Miami lots

A survey is not an inspection of the house. It maps the land and where everything sits on it. In Coral Gables, Pinecrest, Palmetto Bay, South Miami, and Coconut Grove, here's what I see flagged most often:

• Fences and hedges in the wrong place. A fence a few feet inside or outside the legal line is common, and it's the root of most neighbor disputes.
• Pool decks, screen enclosures, and patios over a setback or easement. These are easy to build and hard to unwind.
• Additions that don't match the recorded lot. A garage conversion or second-story expansion may sit closer to a line than current setbacks allow. Pair the survey with a permit history check. I cover that in open permits when buying a home in Miami-Dade.
• Utility and drainage easements. Power, water and sewer, and drainage easements can cut through a backyard where you plan a pool or a guest house.
• Waterfront details. On canal and bay lots, the survey can show where the property line meets the water and how docks and seawalls relate to it.
• Legal access. The survey should show the lot's access to a public road.

None of this is visible on a showing. A survey makes it visible while you still have options.

Who orders it, what it costs, and when

Under the standard Florida Realtors/Florida Bar contract, the buyer typically pays for the survey and the timelines are short. If the seller already has a survey, the contract generally calls for the seller to provide it early in the process, and the buyer then has a short window to object to anything that shows up. Check the title and survey paragraphs of your actual contract for the exact days, because missing that window can cost you leverage.

A few practical points:

1. Order it early. Surveys commonly take one to two weeks, and longer in busy stretches. Ask your title agent to send the surveyor the title commitment so every recorded easement gets plotted.
2. Make sure it is certified to the right parties. That usually means you, your lender if you have one, and the title insurer.
3. Watch the 90-day window. Surveys older than about 90 days may not be enough to remove the exception, and lenders often have their own age limits.
4. Ask about an older survey. Sometimes an existing survey can be accepted with an owner's affidavit, but that is the title underwriter's call, not yours. Don't assume.
5. Read the legend and notes. Every symbol on the survey is defined, and the surveyor's notes often contain the problem.

On cost, think of it as part of your closing budget. A standard lot in Miami-Dade generally runs $300 to $800 as of August 2026. Waterfront lots and anything needing an elevation certificate for flood insurance can cost more. The survey is separate from your title-related costs (owner's insurance, title search, and endorsements). In Florida the owner's policy premium is set by a promulgated rate, and your total title costs include search fees and any endorsements on top of it. I break down how those pieces fit together in closing costs in Miami for buyers.

What to do when the survey shows a problem

A finding is not a dead end. It's leverage for a conversation, handled inside your contract deadlines. Your realistic options are:

• Ask the seller to cure it. Remove or relocate the encroaching fence, get the missing permit, or obtain a written agreement from the neighbor.
• Negotiate a credit or escrow holdback. This makes sense when the fix will take longer than the closing date allows.
• Ask the title agent about affirmative coverage. For some matters, an endorsement can cover the risk. Whether it's offered depends on the underwriter and the facts.
• Walk away within your contract rights. If the issue is serious and the seller won't address it, the cancellation path depends on your contract and its deadlines, so get guidance before the clock runs out.

If your lot sits in a flood zone, the survey is also the right moment to talk about elevation. Flood and wind coverage affect the real monthly cost of ownership, which I walk through in what home insurance actually costs in Miami.

Every lot is different, and the right move depends on what the survey shows and what your contract deadlines allow. This is exactly the kind of review I walk my clients through before they waive or release any contingency.

Frequently Asked Questions

Is a survey required to buy a house in Florida?

Florida law does not require a survey for every residential closing. In practice, many lenders and title companies require one, and without a current survey your title policy keeps a survey exception that leaves boundary and encroachment issues uncovered.

Who pays for the survey in a Miami-Dade home purchase?

Under the standard Florida Realtors/Florida Bar contract, the buyer typically pays. Contracts can be negotiated, so confirm the terms in your own agreement.

How much does a home survey cost in Miami-Dade?

As of August 2026, a standard residential boundary survey in Miami-Dade typically costs about $300 to $800. Waterfront lots and surveys that include an elevation certificate can cost more.

Can I use the seller's old survey?

Sometimes. The title underwriter decides whether an existing survey, usually paired with an owner's affidavit, is acceptable. Surveys older than about 90 days generally will not remove the survey exception on their own.

What if the survey finds an encroachment?

Raise it with the seller in writing within your contract deadline. Options include a cure, a credit, an escrow holdback, title coverage where available, or canceling under your contract rights if the issue is serious enough.

Closing thoughts

A boundary survey costs a few hundred dollars and tells you what the home inspection and the showing can't: where the lot really begins and ends, and what's built across the line.
