On the water and behind a gate in Miami, most of a home’s value and most of its risk sit in records a listing never shows: the lowest bridge between the dock and the bay, the depth at low tide, the seawall’s cap elevation, the permits behind the dock and lift, the flood panel, and the rules of whoever runs the gate. An agent who reads only the house description prices the house and misses the water.

We are The Audrey Ross Team at Compass Florida, and our office sits at 4699 Ponce de Leon Boulevard in Coral Gables. Audrey Ross opened her own firm in 1984, and the team has worked this market for more than 40 years. This guide sets out the questions to put to any agent before you buy or sell a waterfront or guard-gated home in Miami-Dade, and the public record that answers each one, as of November 2026.

What Should You Ask a Miami Waterfront or Guard-Gated Agent Before You Hire Them?

Ask questions only a public record can answer, and listen for whether the agent names the record. The sections below explain each one.

What to ask	Why it matters here	Where to check it
What is the lowest fixed bridge between this dock and the bay?	One fixed span caps the height of every boat that will use the dock.	NOAA chart; U.S. Coast Pilot 4
What depth do the slip and route carry at low tide?	The Coast Pilot reports 5 feet in two local canals (1999).	A current sounding
What is the seawall cap elevation, and which rule applies?	The County, Coral Gables and Miami set different minimums.	Survey; County or city code
Is there a closed permit for every dock, lift and wall?	The County requires a Class I permit over tidal water in every city.	Miami-Dade RER; city records
Which flood zone applies now, and after February 19, 2027?	New FEMA maps take effect that day.	FEMA Flood Map Service Center
Who pays for the gate?	A City guard district bills on the tax bill; a club bills members.	Property Appraiser; club documents
Must a club approve the buyer, and when?	Approval sets the closing date and the contract clause.	Club application and bylaws
Which recorded sales price this lot?	Few homes trade in each enclave.	Property Appraiser search by subdivision

Can the Agent Show You That Your Boat Will Reach Biscayne Bay?

A capable agent answers with the route traced on the current NOAA chart and a recent sounding, not with the listing phrase no fixed bridges. Two comparisons decide whether a boat fits a dock: the lowest fixed bridge on the route against the boat’s air draft, and the shallowest point on the route against its draft.

Both sit on tidal datums. NOAA’s U.S. Coast Pilot gives bridge clearances in feet above mean high water unless otherwise stated, so a higher tide leaves less room than the published figure. NOAA charts refer depths to mean lower low water, which is why a sounding at a known tide is the number to underwrite.

The Coast Pilot, as published November 1, 2026, reports a controlling depth of 5 feet in 1999 for the Coral Gables Waterway, and lists the fixed bridge over the Snapper Creek Canal at 11 feet of clearance. Our guide to deep-water, no-bridge dockage in Miami sets out the City of Coral Gables’ published bridge clearances, and our Snapper Creek Lakes guide traces that community’s marina route.

Why the Answer Is Lot by Lot

Two homes behind the same gate can sit on different water. Snapper Creek Lakes Club describes 124 lots, of which 30 are lakefront and six have direct access to Biscayne Bay. Ask the agent to name the lowest fixed span on the route from that specific dock, its published clearance, and the date and source of the last sounding.

Which Seawall Elevation Rule Applies to the House You Are Buying?

It depends on which government issues the building permit. Miami-Dade County, the City of Coral Gables and the City of Miami each set a minimum for the crest of a new or rebuilt seawall, and they do not use the same vertical datum.

Where the house is	Minimum crest, new or rebuilt wall	Code and date
Unincorporated Miami-Dade	6 inches above the County Flood Criteria elevation, which is never below 6.0 ft NAVD88	County Code s. 11C-9; Ordinance 22-141, October 18, 2022
City of Coral Gables	6 ft NGVD29, built to support 7.5 ft	Zoning Code s. 3-706
City of Miami	6 ft NAVD88; 4 ft NAVD88 on the Miami River, built to be raised 2 ft	City Code s. 29-89; Ordinance 13980, March 25, 2021

Source: Miami-Dade County Ordinance 22-141 (County Flood Criteria Map effective October 28, 2022); Coral Gables Zoning Code, official online code, November 2026; City of Miami Code of Ordinances, version of November 5, 2026. Retrieved November 2026.

The County’s memorandum on the ordinance says Chapter 11C generally applies in unincorporated areas and where the County issues building permits, and that cities may adopt the County map. Coral Gables and Miami issue their own permits, so their own sections govern inside their limits. Coral Gables states its minimum in NGVD29, an older datum than the NAVD88 the County and Miami use, so a surveyor has to convert before the figures can be compared.

When Does an Existing Wall Have to Be Raised?

In the City of Miami, the minimum applies to new construction and substantial improvements. A repair of 50 percent or more of the wall’s length, or costing 50 percent or more of a new wall, brings the whole frontage to the current minimum. Section 29-95 also requires owners to keep walls in good repair, and presumes a wall is in disrepair if it allows upland erosion, lets material pass through it, or lets tidal water flow over or through it to a neighbor’s land or the public right-of-way. The County made rebuilding in place easier: Ordinance 24-136, adopted December 3, 2024, lets a replacement wall within 18 inches waterward of the old one qualify for an administrative short form permit, up from 12 inches, and Ordinance 25-73, adopted July 1, 2025, extends short form eligibility to walls whose support piles sit up to 14 inches waterward, if the new wall is no more than 18 inches waterward of the existing piles.

What Should a Seawall Inspection Cover?

Ask for an engineer’s report on the parts the County’s permit rules name: cracks and spalls on the cap and face, the pilasters, the tieback system and any undercutting at the base, plus the cap elevation from a current survey. Coral Gables requires walls designed by a Florida-registered engineer for the loads of saturated backfill.

Which Permits Should Already Exist for the Dock, Lift and Seawall?

Up to four layers apply to marine work here: the County, the city, the State as owner of the bay bottom, and the federal government. A buyer’s agent should ask for the file on each structure before the inspection period ends.

Section 24-48 of the Miami-Dade County Code requires a Class I permit for work in, on, over or upon tidal waters or coastal wetlands anywhere in the County, including inside every municipality. Under the County’s Class I package, revised May 2025, a single-family dock, davit or boat lift is usually a short form project if none of it protrudes more than 25 percent of the waterway’s width, and most short form permits are valid for two years.

The city layer sets where structures sit. Coral Gables limits a canal dock to 5 feet from the bank or seawall and a boat lift to 25 feet from the bank, and bars any dock, piling or dolphin in Biscayne Bay until the Department of the Army issues a permit. The City of Miami bars building or repairing any waterfront improvement without a building department permit under Section 29-83.

Most submerged land beneath Biscayne Bay belongs to the State, and section 253.77, Florida Statutes, bars construction on state lands without a lease, license, easement or other consent; the County’s package notes that Miami-Dade RER may grant that consent on the State’s behalf where a project meets certain standards. Section 403.813 exempts a private dock of 1,000 square feet or less of over-water surface from a state environmental permit, or 500 square feet in Outstanding Florida Waters, if it meets the section’s other conditions, but not from consent to use state lands. The Florida Department of Environmental Protection describes the Biscayne Bay Aquatic Preserve as Outstanding Florida Waters. Work over the bay may also need federal authorization from the U.S. Army Corps of Engineers, Jacksonville District.

How Should the Agent Read the Flood Map on a Waterfront Lot?

By zone, by elevation and by date, because the maps change on February 19, 2027. FEMA’s Letter of Final Determination list dated August 19, 2026 schedules new Flood Insurance Rate Maps for the City of Coral Gables, the City of Miami and unincorporated Miami-Dade County, along with Key Biscayne, Pinecrest, Palmetto Bay and other Miami-Dade cities, to take effect that day.

FEMA defines Zone VE as coastal areas with a 1 percent or greater chance of flooding and an added hazard from storm waves, and Zone AE as the base floodplain where base flood elevations are provided. Both are Special Flood Hazard Areas, where, FEMA states, homes with mortgages from government-backed lenders must carry flood insurance. In Zone VE, the federal rules that participating communities adopt require new construction and substantial improvements to stand on pilings or columns with the lowest horizontal structural member at or above the base flood level, and a substantial improvement is work costing 50 percent or more of the structure’s market value.

A National Flood Insurance Program policy covers a home’s building up to $250,000 and contents up to $100,000, and typically takes effect 30 days after purchase unless bought with a mortgage transaction. Section 627.715, Florida Statutes, lets authorized private insurers write flood and excess flood coverage that a buyer can price against it. FloodSmart notes that an elevation certificate can lower the price. On a sale, section 689.302 requires the seller’s flood disclosure at or before signing; our guide to selling a luxury home in Miami covers what it asks.

Who Runs the Gate in a Coral Gables Enclave, and Who Pays for It?

In the Coral Gables enclaves below, guards are paid for in one of two ways: a City of Coral Gables guard district billed on the property tax bill, or a private club’s assessment.

Enclave	How the guards are paid	Approval to buy
Gables Estates	Club association fee, which the club states covers 24-hour security; no City guard district line on 2026 tax bills	Yes. The club states membership is a prerequisite to purchasing.
Snapper Creek Lakes	City of Coral Gables Guard District, $3,000 on a 2026 home folio	Yes. Board of Governors approval before ownership.
Cocoplum Section 1	City guard district, $3,865, plus a $500 lighting district, on a 2026 home folio	Read the association documents.
Old Cutler Bay	City guard district, $5,200 on a 2026 home folio	Read the recorded covenants.

Source: Miami-Dade Property Appraiser, Non-Ad Valorem Assessments, 2026 tax roll (one home folio per enclave for the amounts); Gables Estates Club, Inc.; Snapper Creek Lakes Club, Inc., 2024 New Member Application. Retrieved November 2026.

The City districts began under Miami-Dade County. In a mail-ballot election on January 23, 2018, voters in the Cocoplum Phase I, Snapper Creek Lakes and Old Cutler Bay districts approved making the City of Coral Gables their governing body, 88 to 13, 111 to 4 and 161 to 0. The Property Appraiser notes that these charges can become a lien. Where association membership is mandatory, section 720.401, Florida Statutes, requires a disclosure summary before the contract is signed. Our guide to Miami’s guard-gated waterfront communities compares the enclaves. Before an offer, the agent should pull the folio’s non-ad valorem page and the association’s current assessment and put both in your carrying-cost budget.

How Does Club Approval Change the Contract and the Calendar?

Where a club must approve the buyer, approval becomes a condition of the sale and the club’s process sets the closing date.

Snapper Creek Lakes Club’s 2024 New Member Application states that no purchaser may take ownership of property before the Board of Governors approves membership. The application goes in with a non-refundable $100,000 fee and a signed contract, which must state: “This Contract is subject to the purchaser’s being approved and accepted into the membership of Snapper Creek Lakes Club, Inc.” It requires four sponsors who are voting members in good standing. Applicants should anticipate at least 45 days after a complete application. Gables Estates Club, Inc. states that its Board of Governors meets at least four times a year, with meetings each April and November.

An agent who works in these enclaves puts the approval clause in the first draft, sets an outside date that fits the club’s process rather than a generic window, and settles in writing what happens to the deposit if approval is refused. Those terms are negotiated, not set by law. On the selling side, the seller cannot act as the buyer’s sponsor for Snapper Creek Lakes Club approval, so build the approval timeline into the contract.

How Are Homes Priced When So Few Trade Each Year?

Lot by lot, from recorded sales in the same enclave, adjusted for water position, dock and seawall. Gables Estates Club states that its community encompasses 192 lots and Snapper Creek Lakes Club counts 124, so recent comparable sales inside one gate are few and an average price per square foot says little.

The record is public. The Miami-Dade Property Appraiser’s property search runs by subdivision name and shows each folio’s ownership and sales, including whether each recorded sale is treated as qualified. The recorded names differ from the marketing names: Gables Estates sales sit under plats such as GABLES ESTS NO 2 and GABLES ESTS NO 3, and Cocoplum under section plats such as COCOPLUM SEC 1. For a seller, the strongest preparation is a file that answers the water questions first: soundings, permits, the wall report, the survey and the elevation certificate. Our guide on how to choose an agent to sell your Miami home covers the listing agreement and how to compare agents.

How Can You Check an Agent’s Waterfront and Gated-Enclave Record Yourself?

Ask for the agent’s sales list by enclave and by side, then check each sale’s date and price against the Property Appraiser’s records for that subdivision. The county record shows the sale, not the agent, so the side comes from the agent’s brokerage profile. Confirm an active license with the Florida Department of Business and Professional Regulation’s Verify a Licensee search.
