Unincorporated Miami-Dade County Construction Permits – Kendall, Westchester, Tamiami 2026

Unincorporated Miami-Dade County Construction Permits

A significant portion of Miami-Dade County lies outside any incorporated municipality — these areas are known as unincorporated Miami-Dade County. Communities like Kendall, Westchester, Sunset, The Hammocks, Tamiami, West Flagler, Richmond Heights, Perrine, Three Lakes, Country Walk, and large sections of western Miami-Dade are unincorporated. In these areas, Miami-Dade County's Department of Regulatory and Economic Resources (RER) is the permit-issuing authority, the zoning authority, and the code enforcement authority. Many residents mistakenly believe their neighborhood has its own city government — understanding whether your property is in unincorporated Miami-Dade County or within a municipality is the essential first step for any construction project.

How to Determine If Your Property Is Unincorporated

The most reliable way to determine whether a property is in unincorporated Miami-Dade County is to use the Miami-Dade County Property Appraiser's website (miamidadepa.gov) or the Miami-Dade County GIS mapping portal. Searching by property address or folio number will show the municipality designation. If it shows "Miami-Dade County" or "Unincorporated," the property is under county jurisdiction and permits must be obtained from Miami-Dade County RER. The mailing address and the governing jurisdiction do not always match — a property with a "Miami" mailing address may be in unincorporated Miami-Dade County, while a property with a "Kendall" address may be in unincorporated territory, the City of Kendall Lakes (which does not exist as a separate city), or adjacent to a municipality.

Miami-Dade County RER Permitting and Inspection Center

For unincorporated Miami-Dade County, the Miami-Dade County Department of Regulatory and Economic Resources (RER) Building Division at the Permitting and Inspection Center is the permit-issuing authority. The main office is located at 11805 SW 26th Street (Coral Way), Miami, FL 33175. Phone: (786) 315-2100. Website: miamidade.gov/permits. Online permit applications, permit tracking, inspection requests, and fee payments are available through the county's online portal. The Building Official for unincorporated Miami-Dade County oversees all plan review, inspections, and code compliance activities. RER processes permits for all construction types: residential, commercial, industrial, and institutional.

Zoning in Unincorporated Miami-Dade

Unincorporated Miami-Dade County is governed by the Miami-Dade County Zoning Code (Chapter 33 of the Miami-Dade County Code). Chapter 33 establishes zoning districts, permitted uses, development standards (setbacks, heights, lot coverage, parking), and the variance and special exception process. The Zoning Division of RER reviews building permits for compliance with Chapter 33. For projects requiring a variance because the proposed design does not comply with Chapter 33 setbacks or other requirements, a hearing before the Miami-Dade County Board of County Commissioners (sitting as the Zoning Appeals Board) or before a hearing examiner is required. These are quasi-judicial public hearings where neighboring property owners are notified and may testify. Variance proceedings add USD fees and potentially several months to the project timeline.

Kendall and Southwest Miami-Dade Construction Activity

The Kendall area — encompassing Kendall, Kendall Lakes, Kendall West, East Kendall, and Kendale Lakes — is one of the most densely populated unincorporated areas in Florida. Kendall has an extremely active residential construction market: swimming pool installations, home additions, window and door replacements, HVAC replacements, roofing projects, and kitchen and bathroom remodels generate thousands of permit applications to Miami-Dade County RER annually. The suburban character of Kendall — single-family homes on standard residential lots — means that zoning compliance is generally straightforward, but HVHZ structural and product approval requirements apply to all construction, just as they do throughout Miami-Dade County.

The Hammocks, Tamiami, and Three Lakes Areas

The Hammocks, Tamiami, and Three Lakes are unincorporated master-planned communities in southwest Miami-Dade County. These planned unit developments (PUDs) have homeowners associations (HOAs) that impose architectural review requirements in addition to the government's building permit requirements. A property owner in The Hammocks undertaking a home improvement project must obtain both HOA architectural review approval and Miami-Dade County RER building permits. HOA approval does not substitute for a government permit, and a government permit does not substitute for HOA approval — both are legally required. The HOA's architectural review ensures that the design is consistent with the community's aesthetic standards; the government permit ensures that the construction is structurally safe and code-compliant.

DERM Environmental Review in Unincorporated Areas

Many unincorporated communities in Miami-Dade County are located in areas subject to environmental review by the Miami-Dade County Department of Environmental Resources Management (DERM). The Hammocks was developed adjacent to significant natural hammock ecosystems, and tree removal in the area requires DERM tree permits. Tamiami borders the Miami-Dade County Wellfield Protection System, imposing restrictions on underground storage tanks and hazardous materials. Richmond West and Country Walk are near environmentally sensitive areas. For any construction project in unincorporated Miami-Dade County that involves tree removal, stormwater impacts, or work near water bodies or wetlands, DERM review is a mandatory part of the concurrent plan review process. USD fees for DERM review are separate from building permit fees.

Code Compliance and Enforcement in Unincorporated Miami-Dade

Miami-Dade County's Code Compliance and Enforcement Division enforces building codes and zoning regulations in unincorporated areas. Code officers respond to complaints about unpermitted construction and issue notices of violation. Unpermitted structures in unincorporated Miami-Dade County are subject to fines assessed per day until corrected. The Code Relief (Amnesty) program under Ordinance 02-44 provides a path to legalize structures built without proper permits, subject to USD fees, code compliance inspections, and any required structural upgrades. Contractors performing work without permits in unincorporated Miami-Dade County face civil penalties and potential license revocation proceedings.

Abandoned Construction Projects in Unincorporated Miami-Dade

An abandoned construction project in unincorporated Miami-Dade County — where work has begun under a permit but inspections have not been completed and the construction has been left in an incomplete state — is a code violation subject to enforcement action. Fines for abandoned construction projects can exceed $20,000 USD plus the cost of required demolition permits, demolition plans, and site restoration. The property owner is responsible for the condition of their property regardless of whether a contractor abandoned the project. Never begin a construction project in unincorporated Miami-Dade County without confirming that your contractor has the financial resources and commitment to complete the work from start to final certificate of completion or occupancy.

Government Accountability for Unincorporated Miami-Dade Permits

Miami-Dade County RER's Building Division, Zoning Division, Environmental Division, and Public Works all review permits for unincorporated Miami-Dade County. As noted throughout Endless Life Design's permit blog series, government professionals can make errors — incorrect review comments, missed inspection appointments, administrative delays exceeding published timelines. Endless Life Design has caught government mistakes in Miami-Dade County RER permit processing, provided written correction requests citing applicable code provisions, and forced expedited reviews when the county's errors caused project delays. When the government acknowledges its error, USD fees may be waived and expedited processing granted. Property owners and contractors who simply accept government errors without pushing back are leaving money and time on the table.

USD Permit Costs for Unincorporated Miami-Dade

USD permit fees for construction in unincorporated Miami-Dade County are per the Miami-Dade County Building Fee Schedule published by RER. Fees are based on construction valuation. In addition to building permit fees, USD fees apply for zoning review, DERM environmental review, Public Works review, and inspection and reinspection fees. Property surveys ($800 USD to $8,500 USD to update if more than one year old) are often required for permit applications involving structural work, additions, or site improvements. The total USD cost of permitting a residential addition in unincorporated Miami-Dade County — including engineering, architectural, permit fees, and survey — can range from $3,000 USD to $20,000 USD or more depending on the scope and complexity of the project.
