Electrician Services ยป Commercial Electrical Services ยป Common Electrical Problems in Sarasota Retail, Restaurant, and Office Build-Outs | CoHarbor Electric
Commercial build-outs look straightforward from the outside. You find a space, sign a lease, gut the interior, build it back out the way you need it, and open for business. Simple enough in concept. In practice, especially in Sarasotaโs commercial real estate market where a lot of the available space is in older buildings, the electrical side of a build-out is often where projects stall, budgets get stretched, and timelines slip.
Weโve worked on commercial build-outs throughout Sarasota for a long time โ restaurants going into existing kitchen spaces, retail operations taking over former offices, professional services firms moving into older strip center suites along the Tamiami Trail. The electrical problems that come up arenโt random. There are patterns, and they tend to cluster around a few predictable issues that catch tenants and their contractors off guard when nobodyโs done a proper assessment up front.
This is what we see most often, and what you should understand before you sign a lease or break ground on a commercial build-out in Sarasota.
The most common mistake in commercial build-outs โ by a wide margin โ is assuming the existing electrical infrastructure is going to work for the new use. A space that was an insurance office for 15 years might have adequate panel capacity and circuit distribution for computers, phones, and lighting. Put a fast-casual restaurant in that same space and youโve got completely different electrical requirements: hood systems, commercial cooking equipment, refrigeration, dishwashers, point-of-sale at multiple stations. The panel that was fine for the previous tenant canโt come close to supporting the new one.
Weโve walked into spaces in the Gulf Gate area, downtown Sarasota, and along Fruitville Road where a business owner was already mid-build-out and the general contractor had just assumed the electrical was usable. Pulling the panel cover off told a different story โ a 100-amp service that was already near capacity, no room for new circuits, and in a couple of cases, wiring that wasnโt remotely adequate for commercial kitchen loads. Catching that before the build-out starts instead of after saves a significant amount of money and time.
This is a step most business owners skip, and it shouldnโt be optional. Before you commit to a space, having a commercial electrician walk through with you โ or at minimum evaluate the panel and service โ gives you real information about what itโs going to cost to make the electrical work for your use.
At Coharbor Electric, weโve done pre-lease assessments for business owners who were looking at spaces in downtown Sarasota, the Rosemary District, Southside Village, and commercial corridors out toward Bee Ridge and Cattlemen Road. What comes out of that conversation is actual numbers: this space needs a service upgrade, this space already has the capacity you need, this space has good bones but the panel needs to be replaced before you can add circuits. That information changes the negotiation. Sometimes the landlord covers the cost of bringing the electrical up to spec as a condition of the lease. Sometimes it factors into the build-out allowance. But you need to know what youโre dealing with before youโre locked in.
Sarasota has a substantial inventory of commercial space in buildings from the 1960s through the 1980s. Thatโs the era when a lot of the strip centers along the Trail, the smaller office buildings near downtown, and the older retail corridors were developed. Electrical service standards from that period didnโt anticipate what commercial tenants would need 40 or 50 years later.
A 100-amp service feeding a commercial suite was reasonable in 1975. Today, a restaurant or a salon or a medical office in that same suite may need 200-amp service or more. When the service isnโt there, youโve got a few paths: negotiate with the landlord to have the service upgraded, factor it into your build-out budget, or choose a different space. None of those options is great when you find out about it after youโve already signed.
This comes up most often with restaurant and food service clients. A lot of commercial kitchen equipment โ particularly larger refrigeration compressors, commercial dishwashers, and some cooking equipment โ is designed to run on three-phase power. Three-phase is more efficient for high-draw motors and delivers better performance for the equipment.
Whether a space has three-phase available depends on what the building was set up for and what FPLโs infrastructure in that area supports. In some parts of Sarasotaโs commercial corridors, three-phase is readily available. In others, getting it requires significant coordination and cost. If your restaurant concept depends on equipment that needs three-phase power, verifying availability before committing to a space isnโt optional.
Of the three build-out categories weโre covering here, restaurants are consistently the most complex from an electrical standpoint. The combination of high-draw cooking equipment, ventilation requirements, refrigeration loads, lighting demands, and point-of-sale infrastructure means a restaurant electrical scope is almost never simple.
The commercial hood system is one of the most code-sensitive areas of a restaurant build-out. The hood exhaust and makeup air system have specific wiring requirements, and the interlock between the hood system and the cooking equipment โ where the hood has to be running before the cooking equipment can operate โ is a code requirement with fire safety implications.
Weโve been brought in to correct hood system wiring on restaurant build-outs where the original electrical contractor missed the interlock requirements or wired the system in a way that didnโt pass the fire marshal inspection. Thatโs a delay nobody wants when youโre trying to get to opening day. Getting the hood system wiring right the first time, with someone who understands both the electrical code and the specific equipment being installed, is worth the investment.
Walk-in refrigeration units have specific circuit requirements โ dedicated circuits properly sized for the unitโs amperage draw, with correct wire gauge and breaker sizing. Motor loads have high startup current that the circuit has to handle without the breaker tripping on startup. If the circuit isnโt properly sized for the specific unit being installed, youโll have problems from day one.
We see oversized and undersized circuits both cause issues. An undersized circuit trips breakers on startup or runs too hot. An improperly fused circuit doesnโt provide the protection the equipment needs. The right answer is looking at the nameplate data on the actual refrigeration unit and sizing the circuit accordingly โ not just running a โstandardโ circuit and hoping it works.
A commercial kitchen where all the high-draw equipment ends up on the same panel phases is a kitchen with electrical problems. Proper load balancing across phases, dedicated circuits for each piece of high-draw equipment, and clear circuit labeling so the staff can actually manage the electrical system โ these are things that separate a well-done restaurant electrical build-out from one that causes ongoing headaches.
Retail build-outs have different electrical demands than restaurants, but they have their own set of recurring issues. The biggest one is flexibility โ retail spaces change constantly. Merchandise layouts shift, fixtures get moved, new display cases get added. An electrical layout that made sense for the original concept becomes a constraint when the store evolves.
Retail lighting is doing real work โ itโs setting mood, highlighting product, driving purchasing decisions. And modern retail lighting, even LED, means more fixtures and more circuit demand than a vanilla commercial space is typically set up to handle. Weโve done retail build-outs in Sarasotaโs downtown shopping corridors and in the St. Armands area where the lighting design required significant new circuit capacity that the existing panel couldnโt support without an upgrade.
The other lighting issue in retail is flexibility. Hard-wired circuits that lock the lighting layout into a fixed configuration work against retailers who rearrange frequently. Track lighting systems with properly distributed circuits give more flexibility. Planning for that flexibility at the build-out stage costs less than retrofitting it later.
Modern retail point-of-sale systems, security cameras, network equipment, digital signage, and payment terminals all need power โ ideally on dedicated or protected circuits away from the electrical noise that lighting dimmers and other commercial equipment can introduce. A retail build-out that doesnโt plan for technology infrastructure ends up with extension cords and surge strips running across floors, which is both a code issue and a trip hazard.
This is especially relevant in older Sarasota commercial spaces where the existing electrical wasnโt laid out with technology infrastructure in mind. Getting the circuits right during the build-out โ dedicated circuits for network equipment, proper outlet placement for POS stations, conduit for future cable runs โ is much cleaner than patching it in later.
Office build-outs are often underestimated electrically because people assume offices just need lights and outlets. Modern office spaces are considerably more demanding than that โ dense workstation layouts, conference room AV systems, server rooms or IT closets, access control systems, and increasingly, EV charging in parking areas for employees.
Open office layouts pack a lot of workstations into a space. Each workstation has a computer, one or two monitors, phone, and potentially other devices. Multiply that across 20 or 30 workstations and youโve got a significant electrical load that needs to be distributed across enough circuits that no single circuit is overloaded. A common failure mode in office build-outs is running too few circuits to serve too many workstations โ which shows up as tripped breakers in the afternoon when everyoneโs at full load.
The calculation isnโt complicated: figure the load per workstation, factor in a diversity factor for the typical percentage running simultaneously, and design the circuit layout accordingly. But it does need to be done intentionally during the build-out, not worked out after the fact.
Any office with more than a handful of employees probably has a network switch, a router, a patch panel, and possibly a small server or NAS. That equipment needs dedicated circuits โ ideally on circuits that are also protected by a UPS โ and it generates heat, which means the room needs adequate cooling, which means HVAC electrical load to consider.
Weโve done office build-outs in Sarasotaโs professional services corridors near downtown and out toward University Parkway where the IT infrastructure wasnโt scoped into the electrical plan until the GC was already finishing walls. Planning the IT room electrical during the build-out โ dedicated circuits, proper outlet placement, conduit for cable management, coordination with the low-voltage contractor โ is the right approach.
Commercial build-outs trigger code compliance reviews, and electrical is part of that picture. Outlet height requirements, proper GFCI placement, emergency lighting coverage, exit sign placement and wiring โ these arenโt optional. A build-out that skips or shortchanges these areas will fail inspection, require rework, and delay your certificate of occupancy.
In Florida, commercial electrical work requires licensed contractors and permits. Work done by unlicensed contractors, or work done without permits, creates compliance exposure that follows the space โ it can surface during a future inspection, when the business is sold, or when a tenant change triggers a new permitting process.
A lot of business owners coming into their first commercial build-out underestimate how much of the project is driven by the permitting and inspection process. In Sarasota County, commercial electrical permits require submitted drawings for anything beyond minor work, and the review and inspection process takes time.
The practical implication is that electrical work canโt be your last-minute item. Permit applications need to be in early in the project timeline. Inspections need to be scheduled around construction progress. And if something fails inspection โ which happens when the work isnโt done correctly or when the drawings donโt match what was installed โ it adds time and cost to the project.
Working with a commercial electrician whoโs familiar with Sarasota Countyโs permitting process, who submits proper documentation up front, and who does the work correctly so it passes inspection the first time is worth more than it might seem from a pure cost perspective. Rework and inspection failures are expensive, and they push opening dates back.
Coharbor Electric handles commercial electrical build-out work throughout Sarasota and the surrounding area โ downtown and the Rosemary District, St. Armands and the barrier island commercial areas, Gulf Gate, Southside Village, the Tamiami Trail corridor, Fruitville Road, Bee Ridge, University Parkway, and commercial properties in Osprey, Nokomis, and Venice.
Weโre set up for commercial work โ licensed for commercial electrical, familiar with Sarasota Countyโs commercial permitting requirements, and experienced with the specific demands of restaurant, retail, and office build-outs. We work with general contractors, architects, and directly with business owners depending on how a project is structured.
When weโre brought in at the right stage โ before lease signing, or at the beginning of the build-out design process rather than after walls are closed โ the project goes more smoothly and the end result is an electrical system that actually supports how the space needs to function.
Whether youโre opening a restaurant, fitting out a retail space, or building out an office in Sarasota, getting the electrical scope right from the start protects your timeline, your budget, and your ability to operate the space the way you need to.
