Thinking about adding or repairing a dock on Perdido Bay or Old River? The water is inviting, but the rules can feel tricky. You want safe access for your boat, clear guidance on permits, and a design that protects seagrass and holds up through storms. In this guide, you’ll learn who regulates docks in Perdido Estates, when you can qualify for an exemption, what documents to prepare, and how to care for your dock year round. Let’s dive in.
Who regulates docks in Perdido Estates
Escambia County reviews docks as accessory structures and issues local building permits. The county typically requires your approved state and federal paperwork before it will issue a building permit. See how docks are treated in the county’s land development code in this overview of Escambia County’s land development rules.
The Florida Department of Environmental Protection (FDEP) handles Environmental Resource Permits and submerged lands approvals. Many projects use a joint application that routes to the right reviewers.
The U.S. Army Corps of Engineers, Jacksonville District, reviews work in navigable waters. Even small docks can require a notification. You can view current guidance and examples on the USACE Jacksonville Regulatory public notices page.
Permit vs. exemption: what counts
Some small, private docks may be exempt from a full Environmental Resource Permit if they meet strict limits. Florida’s exemption rule outlines thresholds such as being noncommercial, built on pilings, and staying below certain over‑water square footage. Review the criteria in Florida’s exempt activities rule, 62-330.051.
Key thresholds you’ll see:
- One dock per frontage: the one-dock-per 65 feet of shoreline rule applies in many cases.
- Over-water area: 500 sq ft in OFW waters and 1,000 sq ft elsewhere are common exemption caps for private docks.
Even if your dock qualifies for a permit exemption, you may still need authorization to use state-owned submerged lands. Larger or multi-slip docks often require a lease from the Board of Trustees. Read the framework in Florida Statutes, Chapter 253.
Step-by-step permitting checklist
Confirm your boundary and riparian frontage with a current property survey. This helps determine where you can place structures and how much state bottom you might preempt.
Do a quick pre-application check with Escambia County Development Services. Ask about local setbacks, flood zones, and submittal requirements for dock plans.
Commission technical surveys if needed. In areas with seagrass or shallow flats, FDEP and the Corps commonly request bathymetry and a benthic/seagrass survey.
Prepare engineered plans. Include dimensions, materials, pile spacing, walkway width, terminal platform size, boat lift locations, and construction notes that avoid dredging.
Submit the state joint application. In northwest Florida, projects typically use the FDEP joint application package (Form 62-346). File your USACE notification or application as needed.
If required, secure sovereignty submerged lands consent or a lease. Multi-slip or large-footprint docks usually need this proprietary authorization under Chapter 253.
Provide state and federal approvals to Escambia County. The county issues the local building permit after it receives copies of your FDEP and USACE authorizations or exemption letters.
Smart design for Perdido Bay and Old River
Design choices that reduce shading and bottom impacts often move faster through review. Many aquatic-preserve design standards favor narrow walkways and small platforms. See examples in the aquatic preserve design rules, 18-20.004.
- Minimize the footprint. Keep access walkways narrow and use the smallest terminal platform that serves your needs.
- Let light through. Grated or high-open-area decking protects seagrass under the dock. Research shows shading reduces seagrass density; agencies often ask for grating where submerged aquatic vegetation is present. Learn more from this seagrass and docks science summary.
- Elevate and orient wisely. Raising the deck and aligning the pier to reduce shading improves light to the bottom and can ease review.
- Avoid dredging if possible. Single-family docks that rely on natural depths tend to face fewer hurdles than those that propose dredging.
Materials, construction, and safety basics
Choose durable, water-compatible materials like approved treated wood, composite, steel, or concrete. Keep fasteners corrosion resistant and connections tight.
Use construction methods that limit turbidity and bottom disturbance. Driven piles, limited pile counts, and careful staging reduce sediment resuspension.
Build with safety in mind. Include proper lighting, railings where appropriate, and electrical work that meets code, especially for boat lifts.
Daily use and maintenance
Protect seagrass by operating in adequate depth. Keep propellers and hull at least about 1 foot above the bottom at low water when maneuvering. This helps prevent prop scarring; see this local guidance on minimum clearance and shallow-water operation.
Prevent pollution. Never refuel over water, keep absorbent pads and a small spill kit on hand, and avoid in-water sanding or painting. The EPA’s marina guidance explains these best practices in detail in the National Management Measures for marinas.
Plan annual inspections. Tighten hardware, check piles for damage, service lift motors and cables, and remove marine growth carefully so you do not spread invasives.
Hurricane prep for docks and lifts
- Remove or secure loose items early. Stow furniture, hoses, and ladders.
- Prepare the boat and lift. If safe, remove the boat from the lift. If you must leave it, follow manufacturer guidance for strapping and cradle position.
- Install breakaway sections if permitted. Designed weak points can reduce structural damage by releasing in extreme surge.
- Document and photograph. Keep records of permits, plans, and pre-storm condition for insurance and repairs.
Timeline: what to expect
There is no single standard timeline. In general, simple repairs in the same footprint that meet exemption criteria move faster than new docks.
For new docks that need state, federal, and submerged lands approvals, expect a few months at minimum. FDEP often issues Requests for Additional Information and can allow about 90 days for responses, which can extend the process. Larger footprints, dredging, seagrass impacts, or multi-slip layouts typically take longer.
Buying or selling a waterfront home?
If you are purchasing, verify dock permits, inspect the structure, and confirm any submerged lands lease obligations. Ask for copies of FDEP and USACE approvals, the county building permit, and any lease or consent under Chapter 253.
If you plan upgrades after closing, check whether aquatic preserve standards apply to your shoreline. Many design details, such as width limits and platform sizes, are outlined in Rule 18-20.004. Starting with the right survey and plans saves time.

FAQs
Do I need a permit to repair or replace an existing dock in Perdido Estates?
- Many like-for-like repairs or replacements in the same footprint can qualify for state exemptions, but you still need county review and, in many cases, written confirmation of exemption before a local building permit is issued.
What size dock can be exempt on Perdido Bay or Old River?
- Private docks that meet strict limits may be exempt, often capped at 500 sq ft in OFW waters or 1,000 sq ft elsewhere, with the one dock per 65 feet frontage rule also applying.
Will I need a U.S. Army Corps permit?
- Work in navigable waters usually requires at least a notification to the Corps; larger impacts can need a formal permit. Many small docks qualify under general permits, but you should confirm early.
How long does dock permitting usually take?
- Simple, exempt repairs can be quick. New docks that need state, federal, and submerged lands approvals typically take a few months or more, especially if agencies request additional information or if seagrass surveys and mitigation are involved.
What if there is seagrass where I want my dock?
- Expect to provide a seagrass or benthic survey and to design for light penetration using grated decking and elevation. Avoiding shading and prop scarring is often a key permit condition.
Do multi-slip docks need a state submerged lands lease?
- Often yes. When a structure preempts more state bottom than allowed by consent, a lease and added conditions can apply, especially for multi-slip layouts.
Can I dredge to gain depth at my dock?
- Dredging for single-family docks is discouraged and brings more review, likely mitigation, and added federal oversight. Designing to use natural depths is usually the simpler path.
