A buyer closes on a Palm Beach estate in January, envisioning a finished kitchen and a new pool house by the following season. They hire a well-regarded architect, sketch out a scope that would take most Florida municipalities six weeks to approve, and submit it to the Town. Eighteen months later, construction has not started. The project remains in review by the Town's five-member volunteer Architectural Commission, ARCOM, which meets once a month and answers to the Town Council.
Its monthly review is one part of the Palm Beach renovation process. Buyers who understand the commission’s role before they write an offer can plan for the review timeline.
Renovation Timelines to Consider Before an Offer
At any given moment, roughly 80 significant single-family projects are working their way through permitting on the island of Palm Beach. Fewer than half will deliver on the timeline the owner originally set. Owners can consider the commission's review process and evaluation criteria when planning a project.
This matters because the appreciation numbers a buyer arrives with tell only half the story. Palm Beach Island has posted 118.2 percent appreciation over the past five years, with average home values now near $9.8 million and a mid-2025 median single-family sale price close to $12.9 million. Nearly seventy percent of single-family closings in the first half of 2025 cleared $10 million. Those figures describe what the island's real estate has been worth. They say nothing about how long it takes to turn an estate you bought into the one you actually want to live in.
ARCOM's review timeline became a lot more visible after the pandemic buying wave hit the island. As Premier Estate Properties broker Jim McCann told Florida Trend while describing the shift in demand, "We had what I thought was a healthy market, and then COVID hit, and everything went ballistic." New owners sought changes to their properties, whether that meant a full teardown or a simple pergola. ARCOM's docket got longer. The review pace did not speed up to match it.
Three Review Bodies, Not One
Palm Beach Island is not a single regulatory environment. Depending on where a parcel sits, a project can answer to as many as three separate bodies, each with its own scope and its own added weeks.
| Review body | What it covers | Typical timeline impact |
|---|---|---|
| Architectural Commission (ARCOM) | Exterior design, massing, materials, and landscaping | Adds roughly 6 to 12 weeks on top of standard permit review |
| Landmarks Preservation Commission (LPC) | Landmarked properties and historic districts, under Chapter 54 of the Town Code | Full commission review can add months, especially with remands |
| Coastal Construction Control Line (CCCL) | Oceanfront parcels, administered under Florida state law | Runs in series with ARCOM rather than parallel, adding another 3 to 5 months |
A standard permit review for a new single-family home on the island runs 12 to 20 weeks on its own. Layer in ARCOM, and a clean custom residence typically needs additional review time beyond the standard permit process to move from complete design documents to an issued permit, followed by 16 to 22 months of construction. Add an oceanfront lot with CCCL requirements running in sequence rather than alongside ARCOM, and the pre-construction phase alone can stretch past a year.
How Review Steps Affect Renovation Timelines
ARCOM meets monthly. Architects present in person, typically with the owner and general contractor in the room. The commission reviews scale, proportion, exterior materials, and compatibility with the surrounding streetscape. Projects that arrive underprepared get remanded, and each remand costs the owner another four to six week cycle before the next hearing slot opens.
The projects that clear on the first or second try almost always went through a pre-application staff meeting first, a working session where Town staff flag likely objections before they become a formal vote. Recent agendas show the range of work that comes before the commission in a single cycle: a combined renovation and addition at 150 Dunbar Road and 151 Atlantic Avenue, a new two-story residence proposed for 142 Casa Bendita, and storefront signage changes at 259 Worth Avenue.
Historic-District Review and Renovation Plans
If a parcel sits inside one of the island's historic districts, the project answers to the Landmarks Preservation Commission and the standards codified in Chapter 54 of the Town Code, not just ARCOM. More than 328 landmarked properties, sites, and vistas are currently protected under that ordinance, and the LPC meets monthly to review changes to them.
Historic renovations typically run 15 to 30 percent higher in cost than comparable non-historic work, with two to six month timeline extensions common. Historic-district requirements also affect renovation choices. Palm Beach Contractor Authority says replacing a historically significant slate or clay tile roof with asphalt shingles requires full commission review; such a replacement is routinely denied on contributing structures, while in-kind replacement using matching materials can qualify for a faster administrative track. Sabal Luxury Builder says demolition of a contributing structure built before 1965 inside the overlay is not routine, and denial is common. Additions to a historically significant structure must be subordinate in scale, meaning an owner cannot simply match the original design if the original itself is what's being protected.
A Recent Example of ARCOM Review
As Florida Trend reported, developer Todd Michael Glaser, known in Miami Beach for high-end projects including a stint flipping Al Capone's former house, relocated to Palm Beach in recent years; his projects became visible examples of ARCOM review. He paid $85 million for Tarpon Island and $18.5 million for the estate on El Brillo Way once owned by Jeffrey Epstein, which he tore down with plans to replace it with what he described as a design that could one day be a landmark in its own right. Florida Trend reported that he described the ARCOM process as "disheartening"; he had also received prior approvals from the board.
In a Florida Trend report, ARCOM's chairman at the time responded to criticism of the commission's review process:
"We don't need to see every little thing."
That tension, between an owner's desire to move fast on a major asset and a commission's mandate to protect a shared aesthetic, is not going away. In a Florida Trend report, Town attorney John "Skip" Randolph described the general sentiment inside Town Hall as positive, saying that people felt the commission was "doing a good job on behalf of the town." Owners' experiences can differ depending on the review process and any remand cycles.
Plan for Renovation Timelines Before Making an Offer
For anyone weighing a purchase with renovation plans attached, the realistic sequence looks like this:
- Pre-application and schematic design. Four to eight weeks of architectural work before anything reaches the Town's planning desk.
- Staff preview meeting. An informal working session with ARCOM staff that surfaces likely objections early, which is how experienced architects avoid losing the first hearing.
- First formal ARCOM hearing. The commission votes on preliminary approval or sends the project back for revisions, each remand adding four to six weeks.
- Final architectural approval. Detailed elevations, material samples, and window specifications go before the commission a second or third time.
- Permit submission and review. A base 12 to 20 week process through the Town's Building Division, running longer if the parcel triggers CCCL review.
- Construction. Typically 16 to 22 months for a 6,000 to 10,000 square foot custom residence, assuming no major change orders.
Closing before ARCOM approval is common, and most buyers do it. The tradeoff is that carrying costs add to the expense of design and review.
Frequently Asked Questions
What should I budget for if I close before ARCOM approves my renovation plans? Carrying costs add to the expense of design and hearings.
Does buying off-market make the renovation process any faster? The regulatory overlay is identical whether a property sells on-market or off. What off-market access can offer is time, specifically the chance to start a pre-application dialogue with the Town before the parcel is even under contract.
How do I know if my property is inside a historic district before I make an offer? Ask the Town's Planning, Zoning and Development Review office whether the parcel sits within a historic district or overlay, since these trigger Landmarks Preservation Commission review under Chapter 54 in addition to standard ARCOM review. The Town's Planning, Zoning and Development Review office maintains current district maps and can confirm a parcel's status before you write an offer.
If you're evaluating a Palm Beach estate with renovation in mind, the purchase price is only one half of the math. The other half is how realistically you've modeled the months between closing and the first shovel in the ground. The South Ocean Group works these numbers with clients before an offer goes in, not after. Browse homes currently available on the island, or reach out for a free home value consultation if you're weighing whether now is the right time to sell before someone else takes on the renovation timeline instead.
