Retail build out construction in Palm Beach is not the same job it is in a suburban strip center in Lake Worth or Riviera Beach. On Worth Avenue and through the surrounding Worth Avenue District, you're often working inside 1920s–1930s Mizner-era masonry buildings with hollow clay tile walls, cast-in-place concrete slabs poured before anyone thought about conduit routing, and shared party walls where your neighbor's HVAC lineset already occupies the chase you were counting on. Add landlord work letters that protect historic arcade facades and vias, and a build out that looks like a four-week paint-and-fixture job on paper becomes a real construction project. We survey before we price: as-built verification, slab thickness, existing panel capacity and where the sanitary line actually runs.
Permitting is where most retail build outs in the Town of Palm Beach lose their schedule. Plans go through Palm Beach Town Hall, and depending on the address and the exterior scope you may also be looking at ARCOM review for signage, storefront glazing, awnings or lighting visible from the street. That's a calendar-driven process, not a same-week counter approval. Interior-only work still needs sealed drawings for anything touching egress, occupancy load, fire sprinkler head relocation or grease-producing equipment. We assemble the package — architect, MEP engineer, life safety plan — before demo starts, because a Certificate of Occupancy is what actually lets you open the doors, and no fixture install schedule matters until that's in sight.
The tropical climate drives real material decisions. Hot humid summers mean interior spaces that sit vacant between tenants pull moisture into gypsum board, wood trim and MDF millwork; we've opened up North End and Midtown units where baseboard and cabinet backs were already soft before a single trade arrived. We spec moisture-resistant board in back-of-house and restrooms, seal slabs before installing wood or LVT so vapor drive doesn't lift flooring by the second summer, and size HVAC for dehumidification — not just cooling tonnage — because a boutique with cold air and 65% RH will fog glass and curl leather goods. Exterior scope gets impact-rated glazing and stainless or hot-dip hardware; salt air off the ocean in the South End eats plated fasteners fast.
Scheduling around the season is its own discipline. Nobody in the Worth Avenue District wants jack hammers running when The Breakers is full and the Society of the Four Arts has a season calendar going, so landlords commonly restrict noisy demo to early hours, cap deliveries, and shut down loading zones during peak weeks. That pushes serious work into the summer window, which is also hurricane season — meaning open storefronts need a dry-in and board-up plan, and long-lead items like custom storefront systems, glass and commercial HVAC should be ordered months out. We build the schedule backward from your target open date and flag the long leads on day one rather than at week six.
Technician insight
In Palm Beach, the thing that catches most tenants out is assuming an interior fit-out means an easy permit. The moment your scope touches the facade, an awning, a sign or the storefront glass on Worth Avenue, you're into a review calendar that runs on months, not days. The second gotcha is the buildings themselves — a lot of these Mizner-era masonry and clay tile shells have no usable chase for new conduit or plumbing, so what the designer drew as a straight run becomes a saw-cut trench in a historic slab. I always verify panel capacity and where the sanitary line actually sits before anyone prices the job.
Boutique Fit-Out Stalled By An Undersized Electrical Service
A tenant took a small unit off Worth Avenue with a lighting-heavy display design and a signed opening date, then found the electrician wouldn't sign off. We pulled the panel schedule and found an aging service shared with the neighboring suite, with almost no spare capacity once the new HVAC and track lighting loads were added. We re-engineered the lighting to a lower-draw package, coordinated a dedicated subpanel and meter with the landlord, and phased demo into the building's permitted morning noise window. The store opened on its target date and now runs its display lighting at full output without nuisance trips.

How it works
- 1
Site Walk And Existing Conditions Survey
We walk the unit with you and your lease or work letter in hand, verify as-built conditions, check panel capacity, slab and sanitary routing, and identify landlord-restricted scope. You get an honest read on what the space can and cannot do before you commit.
- 2
Design, Drawings And Budget
We coordinate architect and MEP engineer for a sealed permit set, then build a line-item budget with long-lead items flagged. Anything touching the exterior on Worth Avenue or in the historic districts gets flagged for review timing up front.
- 3
Permitting And Landlord Approvals
We submit through Palm Beach Town Hall, respond to comments, and run the landlord approval track in parallel. Insurance certificates, work hours and loading logistics get locked before mobilization.
- 4
Construction And Trade Coordination
Demo, rough-in MEP, inspections, drywall, finishes, fixtures. We work within building noise windows and delivery restrictions, keep the common areas clean, and hold weekly look-ahead schedules so you can plan staffing and merchandise delivery.
- 5
Inspections, Punch And Certificate Of Occupancy
Final trade inspections, life safety sign-off, punch list closeout and handover with warranty and equipment documentation. We stay on it until CO is issued and you can open.
Pricing
Retail build outs are priced per project after a site walk — the space's existing condition, MEP capacity and your landlord's work letter drive the number far more than square footage alone. We give upfront, line-item quotes so you can see where the money goes, and we flag long-lead items and likely permit timelines before you sign. Site walks and preliminary budget conversations cost nothing.
