A guide for business owners planning a retail, office, restaurant, or tenant improvement project
Every build-out, whether for a restaurant, retail shop, salon, office suite, medical space or small business, relies on the right professional team working together. Good coordination protects your budget, your timeline and your permit approval process.
This guide explains the core team members needed for a typical commercial project and what each of them contributes.
1. Architect (Lead Consultant and Project Coordinator)
The architect is typically the first professional hired and is responsible for guiding the design process from concept through permit drawings. The architect:
- Develops layout options and space planning
- Ensures the design meets Nashville building codes, ADA accessibility requirements and zoning rules
- Coordinates with MEP, structural and other consultants
- Prepares drawings for permit submission
- Communicates with the owner, builder and consultants
- Helps anticipate issues before they delay the project or increase costs
For most tenant improvements in Nashville, the architect is the professional who keeps all disciplines aligned so the plans are code compliant and coordinated.
2. Mechanical, Electrical and Plumbing Engineers (MEP Engineers)
MEP engineering is required in nearly every commercial build-out. Nashville and Davidson County reviewers expect stamped MEP drawings for:
- HVAC sizing and duct layout
- Kitchen ventilation
- Electrical service upgrades
- Lighting and emergency egress lighting
- Receptacle and equipment circuits
- Plumbing layout, waste lines, venting and water heater specification
Spaces that almost always require dedicated MEP engineers include restaurants, salons, medical spaces, gyms, bars, retail kitchens, and any project with equipment requiring dedicated circuits or ventilation.
The architect and MEP engineers work together closely to ensure the design meets technical and code requirements.
3. Structural Engineer (Sometimes Required)
Not every commercial project needs structural engineering, but you will need a structural engineer when:
- You remove load bearing walls
- You modify roof framing
- You cut or modify floor slabs
- You design new openings
- You add rooftop mechanical units
- You install heavy equipment
Most small tenant improvements do not require structural work, but the moment a modification affects the building’s structure or roof, a structural engineer becomes necessary.
4. Civil Engineer (Project-Specific)
Civil engineering is needed when a project affects:
- Site drainage
- Parking lot layout
- New utility connections
- Grading changes
- Stormwater requirements
Most interior tenant improvements will not need civil engineering. Build-outs that modify storefronts, add outdoor seating, or adjust site access sometimes do.
5. General Contractor (GC)
The general contractor builds the project and manages:
- Cost estimating and budgeting
- Construction scheduling
- Subcontractors (framing, drywall, electrical, mechanical, plumbing, finishes, flooring, etc.)
- Site safety and inspections
- Communication with the architect during construction
Selecting a GC early helps the owner understand realistic pricing and lead times in the Nashville market. The GC also identifies constructability issues early, which keeps the project from going over budget.
6. Owner / Business Owner (Decision Maker)
The owner’s role is crucial. Owners are responsible for:
- Setting the project goals and priorities
- Approving designs and layouts
- Choosing finishes, equipment and functionality
- Approving the budget
- Completing lease negotiations
- Reviewing timelines and phasing
The owner’s timely decisions are one of the biggest factors in keeping a build-out on schedule.
7. Specialty Consultants (As Needed)
Some project types require additional specialists. The most common for Nashville commercial projects include:
Fire Protection Engineer
For projects requiring sprinklers, fire alarm upgrades or specialized detection systems.
Commercial Kitchen Consultant
For restaurants, café build-outs, bakeries, breweries and bar concepts.
Acoustical Consultant
For music studios, gyms, fitness studios, coworking spaces and venues.
IT and Low Voltage Designer
For camera systems, data cabling, POS systems and AV requirements.
Interior Designer
Helps with furniture layouts, finishes, lighting selections and brand-consistent visual identity.
Surveyor
Needed when exterior modifications occur or when site conditions must be verified for zoning or permitting.
8. The Nashville-Specific Team Benefit
Because Nashville has strict and sometimes lengthy review cycles, having the right professionals in place reduces:
- Permit resubmissions
- Incorrect drawings
- Design conflicts between disciplines
- Budget overruns caused by unforeseen conditions
- Delays in inspections
Coordinated drawings save time and reduce surprises during construction.
