Commercial Electrical Planning Guide for Sarasota Tenant Improvements

Tenant improvements are one of the most common triggers for commercial electrical work in Sarasota, and they’re also one of the most common sources of project delays, budget overruns, and post-completion problems. The reason isn’t that tenant improvement projects are inherently complicated — most of them aren’t. The reason is that electrical planning tends to get treated as something that gets figured out during construction rather than something that shapes the project before it starts.

We’ve been involved in tenant improvement projects throughout Sarasota County for a long time — office renovations in the downtown professional corridor, retail fit-outs in Gulf Gate and along the Tamiami Trail, food service spaces in the Rosemary District, medical office build-outs near Fruitville Road, and commercial suites across the barrier island communities. The projects that go smoothly are almost always the ones where someone involved in the early planning thought seriously about the electrical scope before the first wall was touched. The ones that don’t are usually the ones where the electrical was an afterthought.

This is a practical planning guide for tenants, landlords, and project managers navigating tenant improvement electrical in Sarasota — what to think about before you start, what to expect from the process, and where the common problems actually come from.

Understanding What a Tenant Improvement Is — and What It Triggers

A tenant improvement is any modification a tenant makes to a leased commercial space to fit it for their intended use. That can be as minor as adding a few outlets and reconfiguring some lighting, or as major as a full gut and rebuild of a commercial kitchen or a complete reconfiguration of an office floor plan.

From an electrical standpoint, the scope matters a lot — not just because of the work itself, but because of what that work triggers. Any tenant improvement that includes electrical work beyond the most basic like-for-like replacements requires a permit in Florida. And once you’re pulling a permit for a commercial electrical modification in Sarasota, the work has to comply with current code — not the code the building was built under, but the code in effect today.

That’s a distinction that catches a lot of tenants off guard. A suite in a building from 1985 was wired to 1985 code standards. If you’re doing a tenant improvement in 2025 that involves any meaningful electrical work, the circuits you touch — and in some cases the broader system — need to meet current National Electrical Code requirements as adopted by Florida and Sarasota County. What that means in practice depends on the scope, but it’s a real consideration that affects both the electrical budget and the project timeline.

What Typically Triggers Code Upgrade Requirements

Not every tenant improvement triggers a top-to-bottom electrical code review. But certain scopes consistently bring code compliance into play:

Adding new circuits of any kind brings those circuits under current code. Modifying an existing panel — adding breakers, replacing a panel, reconfiguring circuits — brings the panel work under current code. Relocating or reconfiguring a kitchen or break room area triggers GFCI requirements for the new configuration. Work in any area that involves egress changes affects emergency lighting and exit sign coverage requirements. And in tenant improvement projects that exceed a certain percentage of the building’s assessed value, more comprehensive code compliance reviews can be triggered.

The right approach is to know upfront what the project will trigger — not to discover it mid-construction when it affects the schedule.

Starting Right: The Pre-Project Electrical Assessment

Before a tenant improvement project scopes out, before a lease is signed with a build-out allowance negotiated, and certainly before a contractor breaks ground — someone should evaluate the electrical infrastructure in the space as it exists.

What does the panel serving the suite look like? Is it properly sized for the tenant’s intended use, or is it already near capacity? What circuits are in the space, where do they run, and are they in usable condition? Is the wiring original to the building, or has it been partially updated? Are there any known issues — corrosion, improper modifications from a previous tenant’s work, circuits that don’t function correctly?

For a prospective tenant, this information changes the conversation with the landlord. If the suite needs significant electrical work to support the intended use — and that work wasn’t factored into the landlord’s build-out allowance — the tenant is either absorbing a cost they didn’t anticipate or going back to the negotiating table. Better to know before the lease is signed than after.

For landlords, knowing the electrical condition of a vacant suite before marketing it means no surprises when a prospective tenant’s electrician walks through. It also identifies pre-existing issues that would need to be addressed regardless of the next tenant’s specific requirements.

At Coharbor Electric, we do pre-project electrical assessments for tenant improvement projects throughout Sarasota — evaluating what’s in a space, identifying what works and what doesn’t, and giving tenants and landlords the factual basis for planning and negotiating the electrical scope of the build-out.

Load Calculation: The Math Behind Circuit Planning

One of the most important things that happens during electrical planning for a tenant improvement is the load calculation — figuring out whether the electrical service feeding the space is adequate for the intended use, and whether the panel has room for the circuits the project requires.

This matters most for tenants whose electrical demand is significantly different from the previous tenant’s use. A professional office moving into a space previously used as a storage suite. A food service concept going into a space that was a retail shop. A medical practice going into general office space. In each of these cases, the new use puts very different demands on the electrical system than the previous one did.

Why Existing Service Capacity Isn’t Always What It Appears

Here’s something that trips people up regularly. A suite might have a 200-amp panel, and the tenant assumes that’s adequate for their use. But the panel’s rated capacity isn’t the same as its available capacity. If several breaker slots are already occupied by circuits serving HVAC equipment, shared building systems, or other fixed loads, the available capacity for new tenant circuits may be considerably less than the panel’s nameplate suggests.

Load calculations done properly account for the actual existing load on the panel, the demand of all the new circuits the project requires, and the required headroom for code compliance. In older Sarasota commercial buildings where panels may have been added to over the years without formal documentation, understanding actual load versus theoretical capacity requires someone who physically opens the panel and evaluates what’s there — not just looks at the panel’s nameplate.

Service Upgrades for High-Demand Uses

When load calculations show that the existing service isn’t adequate for the intended use, a service upgrade is the solution. That means coordinating with Florida Power & Light to increase the service feeding the building or the suite, replacing or upgrading the panel to accommodate the higher capacity, and pulling the appropriate permits for the service work.

Service upgrades take time — more time than most project timelines initially account for, because they involve FPL coordination, permitting, and scheduling that’s partly outside the electrician’s control. For any tenant improvement project where a service upgrade might be needed, that process needs to start early. Finding out the service needs to be upgraded six weeks into a build-out means six weeks of delay while waiting for FPL and permit processing to work through.

Electrical Planning for Specific Tenant Types in Sarasota

Different commercial uses have different electrical planning requirements, and understanding what your specific tenant type needs helps scope the project correctly from the start.

Office and Professional Services

Modern office tenants are more electrically demanding than the conventional wisdom sometimes reflects. Dense workstation configurations, server closets or IT rooms, conference room AV systems, access control systems, and increasingly, EV charging for employees or clients — these all need to be accounted for in the electrical plan.

The planning considerations for office tenant improvements in Sarasota generally include: adequate circuit density for workstation areas (how many circuits per station, how the circuits are distributed across the floor plate), dedicated and protected circuits for IT infrastructure, proper placement of outlets relative to the furniture plan, conference room electrical for AV and presentation technology, and any specialized systems the tenant requires.

For office tenants in Sarasota’s professional corridor — downtown, around the Fruitville Road office parks, out toward University Parkway — we’ve seen a consistent increase in the circuit density requirements as companies bring more technology into the workspace. Planning for that at the tenant improvement stage is far less expensive than retrofitting it after move-in.

Medical and Healthcare Offices

Medical tenant improvements have electrical requirements that go beyond standard commercial office work. Exam rooms need specific circuit configurations. Medical imaging or diagnostic equipment has dedicated circuit and power quality requirements that can’t be accommodated on shared circuits. Life safety code requirements for healthcare occupancies are more stringent than for standard office use.

In Sarasota, medical office development has been active — both in the established healthcare corridor near Sarasota Memorial and in satellite locations throughout the county where practices are locating to serve growing suburban residential populations. Tenant improvements for medical office use require electrical planning that accounts for the specific equipment, the occupancy classification, and the life safety code requirements that come with healthcare use.

If you’re planning a medical office tenant improvement in Sarasota and haven’t engaged a commercial electrician with healthcare electrical experience early in the process, that should be the first phone call.

Food Service and Restaurants

Restaurant tenant improvements are the most electrically complex of any common commercial use. The combination of commercial kitchen equipment loads, hood system electrical and interlock requirements, walk-in refrigeration circuits, front-of-house lighting and POS systems, and exhaust and ventilation electrical means the electrical scope of a restaurant tenant improvement is frequently the largest single trade budget in the project.

The critical planning consideration for restaurant tenant improvements is getting the equipment list finalized before the electrical design is done — not after. The circuit requirements for commercial cooking equipment are nameplate-specific. A 60-amp, 240-volt circuit for a fryer that ends up being replaced with a different model requiring an 80-amp circuit isn’t a small change. In a restaurant build-out where walls are closed and the kitchen is being finished out, a circuit change like that is a real cost and schedule problem.

We’ve worked on restaurant tenant improvements in spaces throughout Sarasota — in downtown locations, in the Gulf Gate and South Trail commercial areas, in spaces along the main tourist corridors. The projects that stay on schedule are the ones where the equipment selections were locked down before the rough-in started and the electrical design matched the actual equipment.

Retail and Salon Services

Retail and personal services tenants — salons, spas, fitness studios, and specialty retail — have their own specific planning considerations. Salons and spas use significant amounts of 240-volt equipment: hair dryers, processing equipment, UV systems, spa jets and heating elements. A salon going into a space that was previously general retail needs circuits that the previous configuration didn’t include, and those circuits need to be planned for the actual equipment the salon will use.

Retail lighting is another planning area where getting it right during the tenant improvement pays off. The combination of ambient lighting, accent lighting, and display lighting that makes a retail space work from a merchandising standpoint requires adequate circuit capacity, properly placed junction boxes, and dimming systems that are correctly specified for the fixtures they’ll control. Retrofitting lighting infrastructure after the space is built out is expensive.

Coordinating With the General Contractor and Other Trades

Tenant improvement electrical work doesn’t happen in isolation. The electrical scope intersects with the GC’s overall schedule, with the mechanical contractor’s HVAC work, with the low-voltage contractor running data and communications cabling, and with the plumber on anything involving equipment near water.

The coordination that matters most, and that gets mismanaged most often, is the relationship between the electrical rough-in and the other rough-in work happening at the same time. Walls get closed once — ideally after all the rough-in trades have finished their work in those wall cavities and the rough-in inspections are passed. When the electrical rough-in doesn’t happen on schedule, it either delays wall closing for the whole project or creates a situation where walls are opened back up after they were already drywalled, which nobody wants.

Low-Voltage and Line-Voltage Coordination

Low-voltage work — data cabling, phone lines, security systems, AV wiring — and line-voltage electrical work happen in the same wall and ceiling cavities. Code requires minimum separation between line-voltage and low-voltage conductors in many configurations. When the low-voltage contractor and the electrician aren’t coordinating their rough-in sequencing, you end up with violations that come up during inspection or, if nobody catches them, potential interference problems after the space is occupied.

Getting the line-voltage and low-voltage contractors on the same page — ideally through a pre-construction coordination meeting involving the GC, the electrician, and the low-voltage contractor — prevents most of these conflicts before they happen. It’s a half-hour conversation that saves a lot of headache.

HVAC Electrical Coordination

HVAC equipment requires electrical circuits, and those circuits need to be properly sized and located relative to the equipment’s actual installation position. When the HVAC layout changes during a project — and it often does — the electrical for the HVAC equipment needs to follow. An HVAC disconnect that was planned for one wall location and ends up needing to serve a unit that got moved 15 feet is a field change that affects the circuit routing, the conduit run, and potentially the permit drawings.

For tenant improvements in Sarasota where the HVAC scope includes new equipment — which is common in older buildings where existing HVAC is being replaced as part of the tenant improvement — the electrical planning needs to account for the actual equipment selections and their specific electrical requirements before the rough-in starts.

Permit Management for Sarasota Tenant Improvements

Commercial tenant improvement electrical permits in Sarasota follow the same jurisdictional structure as other commercial permits — Sarasota County for unincorporated properties, the City of Sarasota for properties within city limits, and the City of Venice for Venice properties. The permit process for a tenant improvement follows the same general path as a full build-out permit, but the scope of the documentation required scales with the complexity of the electrical work.

For smaller tenant improvements — adding circuits, reconfiguring lighting, adding outlets — the permit application and drawings can be relatively straightforward. For larger scopes involving panel replacements, service upgrades, or complex systems like commercial kitchen electrical, the documentation requirements are more extensive and may require engineer-reviewed drawings.

Timeline Reality for Tenant Improvement Permits

One of the most common project management errors in tenant improvement projects is not starting the permit process early enough. In Sarasota County and the City of Sarasota, commercial permit review takes time — several weeks for straightforward scopes, longer for complex ones or during busy periods. If the permit application goes in after construction is already underway on other scopes, the electrical work may be sitting and waiting for a permit while the rest of the project moves forward.

The permit needs to be in hand before electrical work begins. That means the permit application, along with complete and accurate drawings, needs to be submitted weeks before the anticipated electrical start date — not days before. Build that timeline into the project schedule explicitly, not as an assumption that it’ll work out.

Coharbor Electric handles the permit documentation and submission for tenant improvement projects we’re involved in throughout Sarasota County and the City of Sarasota. We know what each jurisdiction’s plan review process requires, we submit complete applications the first time, and we track the review process so we know when the permit is in hand and work can begin.

Mistakes That Derail Sarasota Tenant Improvement Projects

These come up enough to be worth naming plainly.

Finalizing the lease before evaluating the electrical. The build-out allowance, the timeline, and the project budget all depend on what the electrical scope actually is. That scope depends on what’s in the space and what the tenant’s use requires. Signing the lease before that evaluation is done means the financial and timeline assumptions are based on unknown information.

Changing equipment selections after the rough-in. Electrical circuits are sized for specific equipment. Changing equipment after circuits are rough-in means either accepting a circuit that’s not correctly sized, or tearing open walls to replace conductors. Lock down equipment selections before the rough-in starts.

Treating low-voltage as separate from the electrical scope. Data cabling, security systems, and AV wiring all interact with the electrical design. They share wall cavities, they need coordinated box placement, and in some cases they need line-voltage power sources at specific locations. A tenant improvement that’s planned without integrating low-voltage requirements into the electrical design produces a space that needs retrofitting before it’s fully functional.

Assuming the landlord’s build-out allowance covers actual electrical costs. Build-out allowances are often calculated on a per-square-foot basis using general assumptions about fit-out costs. For tenants whose use is more electrically intensive than generic office or retail — restaurants, medical offices, salons, fitness studios — the actual electrical cost may significantly exceed what’s covered in the allowance. Understanding the gap before signing puts the tenant in a position to negotiate rather than absorb it.

Not coordinating inspection timing with the construction schedule. The rough-in inspection has to happen before walls close. If the inspection isn’t scheduled in time, either the wall closing gets delayed or the walls close and have to be opened back up. Build inspection milestones into the project schedule as firm dates, not floating items.
