Just a few miles north of Jupiter Inlet are two of South Florida’s most private towns. Both provide breathtaking views of the water. Also, the building rules in both are some of the strictest on the coast. A project might be delayed for months by a single mistake.
This guide explains Jupiter Island building requirements and Jupiter Inlet Colony. You’ll know what to anticipate whether you’re planning a major home improvement or a new estate.
What Are The Jupiter Island Building Requirements?
Jupiter Island building requirements include acquiring a local permit, hiring licensed contractors and subcontractors, passing a zoning review, and adhering to regulated seasonal working hours. Additionally, every project must adhere to the Florida Building Code, Eighth Edition (2023). The town’s Building Department is in charge of all of its planning, permits, inspections, licensing of contractors, and code enforcement.
Who Issues Permits On Jupiter Island?
All permits are issued by the Town of Jupiter Island Building Department, located at 2 Bridge Road in Hobe Sound. The office can be contacted at 772-545-0150.
How Long Does A Permit Last?
From the date of issuance, a permit is good for 18 months. If work does not begin within 6 months, it becomes null and invalid.
Key requirements:
- Every contractor, including subcontractors, needs to register with the town
- No work can start until the permit is granted
- Document a Notice of Commencement before starting any work
- Florida Statute 489.103 must be followed by owner-builders
Can You Build On Your Own?
Yes, but only to a certain extent. With Florida’s owner-builder exemption, you can build a house for yourself. It cannot be leased or sold within a year, and you must personally oversee the work.
Before breaking ground on any project, make sure it is properly registered, recorded, and follows all building codes.
What Are Jupiter Inlet Colony’s Building Rules?
In Palm Beach County, Jupiter Inlet Colony is a distinct community with its own set of regulations. Before applying for a permit, the Building and Zoning Committee must assess new buildings and significant renovations. Applicants can apply for permits online using the My Government Online (MGO) system.
How Big Can A Two-Story Home Be?
No more than 32% of a two-story lot may be occupied by buildings. The second floor’s area cannot be more than 60% of the first floor’s.
How Are Contractors Approved?
When requesting a permit, all businesses are required to first register as contractors with MGO. This is the first, not the last, step.
| Feature | Jupiter Island | Jupiter Inlet Colony |
| County | Martin | Palm Beach |
| Permit office | Town Building Department | Town, via MGO portal |
| Pre-permit review | Zoning and plan review | Building and Zoning Committee |
| Two-story lot coverage | Varies by district | 32% max |
| Seasonal work limits | Yes, strict | Check town code |
| Best for | Large estate lots, privacy | Smaller lots, inlet access |
Are The Rules Of The Two Towns The Same?
No. They are different jurisdictions with their own building departments, phone numbers, and portals. You may lose out on a complete review cycle if you file in the wrong town.
Jupiter Inlet Colony places more emphasis on housing size and mass, although both towns preserve their low-density nature.
When Is Building Permitted On Jupiter Island?
Jupiter Island limits building based on the season. Summer lasts from May 1 to October 31, whereas winter lasts from November 1 to April 30. Any equipment that produces more than 72 decibels is prohibited, and loud “restricted” equipment is prohibited throughout the winter.
| Season | Weekdays | Saturdays | Restricted Equipment |
| Summer (May 1 to Oct 31) | 7:30 AM to 6:00 PM | 8:30 AM to 5:00 PM (with permission) | Weekdays 7:30 AM to 6:00 PM |
| Winter (Nov 1 to Apr 30) | 8:30 AM to 5:30 PM | 8:30 AM to 1:00 PM | Not allowed |
What Equipment Is Considered Restricted?
Outdoor power saws and mowers that can move dirt and gravel weigh two tons or more. Within a “dried-in” structure, saws are permitted.
How Should Your Project Be Timed?
Plan to clean the site and demolish it in the summer. Keep interior work quieter for the winter.
Is It Possible To Get An Exception?
Sometimes. Give the building official a written request at least 5 business days in advance. Approval is based on neighbor impact and noise levels.
One of the easiest ways to prevent delays is to strategically plan around these seasons.
How Do Coastal Rules And Climate Affect Your Build?
In this area, houses are built to withstand the salt air, flooding, and hurricane gusts. Every coastal home must adhere to the Florida Building Code’s flood, wind, and impact standards. Lots that are right on the beach often need extra states permits. These are more expensive and time-consuming, but they protect your investment for many years.
- Wind: Engineered roof connections and impact-rated windows and doors
- Flood: FEMA flood zone maps set floor heights
- Salt Air: Corrosion-resistant coatings and stainless steel fasteners
- Beachfront: Coastal Construction Control Line (CCCL) permits issued by the Florida Department of Environmental Protection (FDEP)
Why Does Salt Air Matter?
Salt accelerates the rusting of hardware, HVAC systems, and metal. Using better materials now will save you money in repairs later on.
Do Beachfront Lots Need Extra Permits?
Yes, most of the time. Along with town permits, work done near the CCCL needs to be approved by the FDEP.
Plan early for coastal rules because they affect how things are built, how much they cost, and how often they need to be adjusted.
How Much Does Building Cost In Jupiter?
These towns have higher building costs than most of Palm Beach. High-end finishing, seasonal work restrictions, coastal engineering, and strict rules all drive up costs. Get a comprehensive, itemized quote from a builder in your area before you buy land.

When Is It Time To Choose Each Town?
