Historic Building Renovation in Florida: What Owners Need to Know Before Work Begins

Key takeaways:

• Owners often underestimate how much existing conditions, preservation requirements, code upgrades, and material choices can affect a historic renovation.
• Preserving character does not mean sacrificing safety, code compliance, or business function.
• The right General Contractor protects the owner from costly surprises, poor sequencing, and unnecessary change orders.

Older buildings have big potential. But they require big plans.

There’s something special about historic buildings. Because of their unique shapes or craftsmanship, they really stand out, particularly when surrounded by modern structures that often all look the same. 

Historic buildings also have their own character, and their location in a community can harken back to a bygone era. 

This doesn’t mean that they’re museums, however, as decades-old (or maybe even centuries-old) buildings can still be functional. 

But when a historical building renovation is necessary, owners have to understand that this can be significantly different from a standard commercial buildout. 

To bring a space back to life or add updated amenities, there are numerous areas to consider, and this has to happen well before work begins.

What Owners Should Know Before Renovating a Historic Building

Any construction project requires extensive planning, and this is particularly true when it comes to renovating a historic building. 

Key areas that need to be a focus include:

• The location of the property and whether it’s locally designated, listed, or part of a historic district.
• Approvals that may be needed include exterior work, signage, window changes, additions, and major alterations.

Most historic buildings have been in existence for a very long time, and as such, there are often underlying issues that may not be obvious on the surface. 

This is why owners need to closely evaluate early on:

• Roof
• Foundation
• Moisture
• Old repairs
• Electrical
• Plumbing
• HVAC
• Accessibility
• Life-safety needs

Restaurants and retail spaces typically have specific needs to plan for, such as:

• Kitchens
• Restrooms
• Ventilation
• Grease systems
• Electrical loads
• Customer flow
• Storage
• Back-of-house needs

It’s not uncommon for hidden conditions to arise during a construction project on a historic building. 

These could include things like water damage, bad wiring, or hazardous materials, and owners need to be aware of this when devising budgets and timelines. 

It’s important to remember that historic renovations are won or lost before construction begins.

Valuable Resources for Florida Property Owners

Owners of historic buildings in Florida have to know that everything they intend to do with their properties is above board. 

Fortunately, the Florida Division of Historical Resources can help. This agency provides reviews and technical assistance related to preservation compliance. In addition, Florida building code resources should be checked during planning because requirements and supplements can change.

What Makes Historic Renovation Different from Standard Construction

When starting a construction project with an empty lot or shell of a building, you basically have a clean slate to work with, and this can give you a lot of options. 

That’s not the case, however, with a historic building renovation. Not only is it already built, but it also has a story and a place in the community. It may also have stringent limitations, as well as the possibility of surprises. 

It is important to remember that existing conditions drive many project decisions. For example, instead of being replaced, original materials may have to be repaired. Design choices might need to respect the building’s historic character. 

When making changes or additions, they have to feel compatible without pretending to be original. Building codes, accessibility, fire safety, and modern business needs must be layered into an older structure. Historic renovation is not just construction; it’s careful problem-solving.

Another good resource to consult is the National Park Service and its rehabilitation standards. These emphasize preserving historic character, avoiding unnecessary removal of historic materials, repairing deteriorated features when possible, and making new work compatible with the historic property.

How a General Contractor Preserves Character While Updating the Building

The question of “character” is one of the most important things to consider when deciding to make major changes to a historic building. 

In order to preserve character without sacrificing safety, comfort, or business function, these steps need to be taken:

1. Documenting what’s already there.
2. Identifying character-defining features worth preserving.
3. Separating what must stay, what can be repaired, and what can be updated.
4. Bringing in modern systems carefully.
5. Using materials and finishes that fit the building.
6. Keeping new work functional, safe, and compatible.

Examples include:

• Preserving:
  • Storefronts
  • Masonry
  • Wood floors
  • Exposed beams
  • Original ceilings
  • Historic windows
  • Tile
  • Millwork
  • Façade details

• Hiding or carefully routing:
  • New HVAC system
  • Plumbing
  • Electrical
  • Lighting
  • Fire-safety systems

• Cleaning and repairing historic materials with the least aggressive method that works.
• Choosing replacements that match the original look when repair is not realistic.

Why the Right General Contractor Matters

A successful historic renovation requires coordination between all stakeholders, including:

• Owner
• Architect
• Engineers
• Preservation professionals
• Local officials
• Specialty trades
• General Contractor

The General Contractor may be the most important of all, as they help owners understand what is happening now and what is coming next. 

They also work to prevent costly change orders, poor sequencing, and unpleasant surprises with early estimating, planning, sequencing, and value engineering.

When choosing a General Contractor, keep in mind that the lowest bid may not be the safest choice if it misses hidden conditions, preservation requirements, material needs, or code upgrades. 

So, what makes a strong General Contractor for a historic building project? One that prioritizes clear communication, has a dedicated project team, and focuses on conceptual planning. 

They should also have extensive experience and a proven track record of working on historical renovations. 

Quick Owner Checklist Before Work Begins

Don’t begin a historic building renovation until you closely review this checklist:

1. Confirm whether the building has historic status or local review requirements.
2. Walk the property with experienced construction professionals before finalizing the budget.
3. Evaluate structure, moisture, MEP systems, accessibility, life safety, and code needs.
4. Identify which original features should be protected.
5. Plan for restaurant or retail operations early.
6. Set a realistic contingency.
7. Ask how the project team will communicate changes, timelines, and next steps.
8. Bring in a General Contractor before the design is too far along.

A Note About Accessibility

Restaurants, stores, and many public-facing businesses are covered as public accommodations. 

This means that any altered facilities must be made accessible to the maximum extent feasible. Just because a building is older does not automatically shield it from accessibility obligations.

Respect the Past, Build for What Comes Next

Even if they have been neglected or poorly maintained, it’s possible to rejuvenate old buildings and turn them into beautiful and useful commercial spaces. 

This starts with the owner working with the right team to create the right plan.
