Why Lighthouse Point is a cap-and-dock market
Lighthouse Point is a small boating city where many homes sit on deep canals that open to the Intracoastal near the Hillsboro Inlet. Its code is also unusual. Instead of a single 5 foot rule, Section 42-381 sets a minimum cap elevation of 4.0 feet NAVD88 and lets owners raise or cap a wall up to 5.0 feet (Ordinance 2023-0998). Raising is allowed, not required, so the cost question here is often a cap question: repair it, rebuild it taller, or leave the wall as it is.
| Work | Published range | Source |
|---|---|---|
| Partial cap repair | $1,500 to $4,500 per job | JKT Marine |
| Full cap replacement | $3,000 to $10,000 per job | JKT Marine |
| Cap repair or replacement, per foot | $600 to $900 per linear foot (Fort Lauderdale guide); $125 to $230 for caps and tiebacks (national) | Waterfront Repair FL, Angi |
| Moderate repairs, per foot | $100 to $250 per linear foot | Souffront |
| New concrete panel wall, installed | $250 to $400 per linear foot | JKT Marine |
What the Lighthouse Point code does to a quote
- Design for a 5.0 foot cap, even if you build lower. Any new wall, and any wall being substantially rehabilitated, replaced, maintained or improved, must be designed to accommodate a 5.0 foot cap. The staff report explains that a wall built lower has to be able to support one more foot later. A cheaper low wall is therefore not a lighter wall.
- Old coral rock walls. The staff report notes that many city walls are coral rock and more than 50 years old, and that they often cannot carry the weight of building on top. Pouring a taller cap on one may not be an option, which turns a cap job into a wall job. An inspection comes before any plan to raise.
- Return walls when you go higher than a neighbor. If your new wall will be higher than a neighbor's, as determined by a licensed surveyor or engineer, return walls must be built on your own property, parallel to the property line, until the grades match. That is added length and concrete beyond the wall itself.
- Tolerance. A cap from 3 feet 8 inches to 5 feet 4 inches NAVD is treated as conforming, which gives the surveyor and builder some room but not a way around the design rule.
- No adopted deadline to raise. The code sets no 2035 or 2050 date and no citation timeline, so ask the Building Department how it handles a wall that lets tide water through before you plan a budget around a date.
- Longshore insurance. The city checklist points to the federal Longshore requirement for work over navigable water and says state workers' compensation does not satisfy it (city checklist). Ask every bidder whether they carry it.
How Lighthouse Point calculates the permit fee
The city's building permit fee schedule bases the fee on the cost of construction as the applicant attests on the permit application, per trade (fee schedule):
| Item | Published rate |
|---|---|
| Minimum permit fee | $125 |
| Construction costs up to $5,000, per trade | $125 |
| Construction costs above $5,000, per trade | Plus 1.35 percent |
| Application fee, all other permits | $100, applied against the final permit cost |
| Plan re-review, re-inspection | $95 per hour for re-reviews, $95 per re-inspection |
| Concrete dock over a seawall cap | $300 for the first City Engineer review, plus actual cost for additional reviews |
The permit fee includes the first plan review and standard inspections. If the Building Official thinks the stated cost is too low, the fee can be based on a signed contract or on RS Means valuation, whichever is greatest. The Building Department's checklist also asks for outside agency approvals from Broward County, the Florida DEP or the Army Corps of Engineers, signed and sealed plans, a Notice of Commencement and an updated dock and seawall survey before the final inspection.
A worked example for a 60 foot Lighthouse Point wall
The published new-wall range used in these examples is $250 to $400 per linear foot for an installed concrete panel wall (JKT Marine). It is arithmetic on published figures, not a quote, and it leaves out demolition, dock work and difficult access. For 60 feet that is $15,000 to $24,000 for the wall.
| Line | Low end | High end |
|---|---|---|
| New wall at $250 to $400 per foot | $15,000 | $24,000 |
| Building permit: $125 plus 1.35 percent above $5,000 | $260 | $381.50 |
| Broward County general license application | $200 | $200 |
| Construction plus those two fees | $15,460 | $24,581.50 |
Lighthouse Point's own fee is a very small share of this job. The larger lines are the engineer's design, the survey, return walls where they apply, and the contractor's insurance and permitting work; one South Florida contractor publishes $2,000 to $5,000 for engineering and $800 to $3,000 for permits on a typical job (JKT Marine).
