In short
- A dock that reaches more than 6 ft has to stay back from the ends of your water frontage line.
- Regular lot: 12 ft each side.
- End, adjacent or lake lot: 12 ft at 80 ft of frontage or more; (frontage - 40) x 0.3 between 40 and 80 ft; zero at 40 ft or less, plus a center band.
- Enter your lot and plan to see each side against the rule.

This dock side setback calculator is for Cape Coral canal owners who are planning a new dock or a rebuild and want to know how far it has to sit from the ends of the lot before they ask contractors to draw it. Pick your lot type, enter the water frontage and your plan, and it applies the offsets in Land Development Code section 5.4.3. Where the text can be read two ways, it shows both. It uses code text only, with no prices. For how far the dock may reach, see the dock projection calculator, and for deck area the dock size limit calculator.

Example: regular lot with 60 ft of frontage, a dock 20 ft out and 30 ft wide, placed 9 ft from one end. Illustrative numbers, not a recommendation.
How the check works
- Pick the lot type.
Regular, end or adjacent. Each uses a different rule.
- Enter the water frontage.
The length of the lot along the seawall. On end lots it sets the setback.
- Enter the plan.
Reach, width along the shore and the gap to the nearest end.
- Read each side.
The tool compares the gap on each side with the setback required.
- Take any shortfall to your builder.
Ask what can move before the permit drawings are sealed.
The rules the checker uses
| Case | Rule | Code section |
|---|---|---|
| Reach of 6 ft or less | May run the full frontage | 5.4.3.A.2 |
| Regular lot, over 6 ft | 12 ft from each extended side property line | 5.4.3.A.1 |
| End or adjacent, 80 ft or more | 12 ft from each end of the frontage | 5.4.3.A.5.b |
| End or adjacent, over 40 and under 80 ft | (frontage - 40) x 0.3 from each end | 5.4.3.A.5.c |
| End or adjacent, 40 ft or less | Ends of the frontage, and within 10 ft of the center on each side | 5.4.3.A.5.e |
| Pilings and mooring posts | 2.5 ft from a storm drain pipe | 5.4.2.E |
Side setback by water frontage
| Frontage (ft) | End or adjacent (ft) | Regular lot (ft) |
|---|---|---|
| 30 | 0 | 12 |
| 40 | 0 | 12 |
| 50 | 3 | 12 |
| 60 | 6 | 12 |
| 70 | 9 | 12 |
| 80 | 12 | 12 |
| 100 | 12 | 12 |
Setback on each side for a structure that reaches more than 6 ft. At 40 ft of frontage or less the setback from the ends is zero, but the 20 ft center band applies. The code gives no frontage-based figure for a regular lot, so the 12 ft column does not change.
Where the code text can be read two ways
For an end or adjacent lot with 40 ft of frontage or less, the code says two things. The marine improvement area rule (5.4.3.A.10.a.iv) puts the offset points at the ends of the frontage, which is zero. But the small-lot rule (5.4.3.A.5.e.ii) says nothing over 6 ft out may extend more than 10 ft either side of the center of the frontage. We show both readings and the worse one decides.
| Reading | Rule | Example: 36 ft frontage |
|---|---|---|
| A. Inside the lot ends | Setback 0 at each end | passes |
| B. Center band | Within 10 ft of center: at least 8 ft from each end | 6 ft: fails |
| Verdict | Passes A but not B: ask the city | unclear |
Example: 36 ft of frontage and an 18 ft wide structure placed 6 ft from one end sits 12 ft from the other end, so it passes A. The center band needs at least 8 ft from each end, so the tool flags B.
What the numbers do not cover
Meeting the setback does not mean a permit. Reach, deck area, the open navigable water rule and the building permit are separate checks, and the permit reviewer decides. Outside corners, lake and basin corners and the Caloosahatchee River use areas the city draws or state and federal rules. The permit steps are in the dock and boat lift permit checklist, and the piling and deck heights are in the dock construction code calculator.
Questions to ask your dock builder
- How far is the design from each end of the lot? Ask for both gaps on the drawing.
- What type of lot is mine? Regular, end, adjacent and corner lots use different rules.
- What is my marine improvement area? If the lot is at a canal end or on a lake, ask for the drawn area.
- Is there a storm drain pipe nearby? Pilings must sit 2.5 ft from it.
- How do I choose a builder? See choosing a seawall contractor.
Next step: get a written quote
This tool checks numbers, not the job. We are a referral service, not a contractor; we connect visitors with independent local providers. Use the form below to ask independent local seawall and dock contractors for a written quote, and ask each to state the gap to both ends of the lot.

Frequently asked questions
How far from the end of my lot does a Cape Coral dock have to be?
On a regular canal lot, a structure that reaches more than 6 ft from the water frontage line has to stay 12 ft from each extended side property line (Land Development Code section 5.4.3.A.1). A structure that reaches 6 ft or less may run the full frontage.
Does the setback change on a canal-end lot?
Yes. On end, adjacent and lake or basin lots the setback depends on the frontage: 12 ft with 80 ft or more, (frontage minus 40) x 0.3 with more than 40 and less than 80 ft, and zero at the ends for 40 ft or less. At 40 ft or less the structure must also stay within 10 ft of either side of the center of the frontage.
How far can a dock reach on an end lot?
The text sets 30 ft for end lots. An adjacent lot may reach 30 ft or 25 percent of the canal width, whichever is less. At 40 ft of frontage or less the text offers a platform dock up to 10 ft wide and 16 ft out, or up to two finger piers with 6 ft of deck in all reaching up to 30 ft.
How far from a storm drain pipe does a piling have to be?
Section 5.4.2.E requires pilings and mooring posts to be offset at least two and one-half feet from any storm drain outfall pipe, measured from the outside edge of the pipe to the center of the piling.
Which lots does this tool not cover?
Outside corners of two canals, lake and basin corners, and the Caloosahatchee River. Those use areas the city draws or state and federal rules, so ask the city for the marine improvement area of your lot.
