Zoning & land use come first
Before any dock, seawall, or lift is designed, your project has to fit Miami-Dade County’s zoning and land-use rules. Confirming this early is the cheapest way to avoid a redesign later.
Zoning district
Your parcel's zoning (residential, conservation, waterfront overlay) sets what marine structures are allowed and how close to the property line and water they can sit.
Setbacks & limits
Riparian setbacks, dock length and coverage caps, height limits, and shoreline buffers are checked against your survey before a permit can move forward.
Overlays & approvals
Coastal construction, manatee-protection, or special overlay zones can add a zoning review or variance step — worth confirming before you spend on design.
Zoning rules are set locally and change over time. Always confirm the current requirements for your specific parcel with the Miami-Dade County zoning or planning office (or a licensed professional) before relying on them.
Your permitting journey, end to end
A typical Florida waterfront project moves through six phases. Many overlap — the survey can start while zoning is confirmed — so the whole journey usually runs shorter than adding every phase together.

Typical ranges for residential Florida waterfront projects. Many phases overlap, so the whole journey usually runs shorter than adding every phase together. Permit review timelines vary by county, agency, project type, and how complete your first submission is — these are planning estimates, not guarantees.
Before you can apply
Permit review is the last leg of the journey. Most projects need a few professional steps completed first — these often start with Surveying, followed by Engineering and shape your overall timeline.
Surveying
2–4 weeksA licensed surveyor documents your shoreline, water depths, and property lines — the foundation every drawing is built on.
Engineering
3–4 weeksAn engineer prepares stamped plans for your dock, seawall, or lift so the design meets code and can be reviewed.
Environmental assessment
2–4 weeksSeagrass, resource, and habitat checks confirm your project protects the waterway before it reaches an agency.

Who reviews marine permits here
Depending on your project and its location, review can involve the county itself, state agencies, water management districts, and federal reviewers. In the records we analyzed for Miami-Dade County, these agencies appear most often:
What to expect
A clean, complete submission in Miami-Dade County typically reaches a decision in about 27 days — but incomplete applications can take far longer once correction rounds start.
Most delays are avoidable: missing surveys, unsigned engineering, or overlooked agency sign-offs are the usual culprits behind requests for more information.
The Tideway platform uses historical permitting data and TideAI to help identify likely requirements and common problems earlier, so submissions are less likely to come back for avoidable corrections.
A complete, internally consistent package in front of every reviewer the first time is the best way to reduce the rounds of agency corrections that add calendar time.
About these numbers: benchmarks are computed from 13,743 public permit records filed 2005–2026 across the agencies that publish data for Miami-Dade County. Medians describe past filings, not promises — every project is different, record coverage varies by agency and year, and processing times change. Timeline figures reflect the 9,078 records with complete application and approval dates.
