Challenges in Historic Restoration Projects in Tampa
Historic restoration projects in Tampa present unique challenges—from regulatory compliance and hazardous materials to structural deficiencies and material sourcing. Here's how experienced contractors overcome them.
Historic restoration projects in Tampa demand a level of expertise that goes far beyond conventional construction. From navigating the multi-layered regulatory environment to managing unexpected discoveries behind century-old walls, these projects test even experienced contractors. Understanding these challenges—and having strategies to address them—is essential for protecting your investment and achieving successful outcomes.
Florida Construction Specialists has encountered and overcome virtually every challenge that Tampa's historic buildings can present. Our experience with projects throughout Ybor City, Hyde Park, Tampa Heights, and other historic districts has equipped us with the knowledge and relationships needed to navigate complex restoration projects successfully.
Regulatory and Compliance Challenges
Navigating Multiple Review Authorities
Tampa's historic properties often fall under multiple jurisdictions, each with its own review process and standards. A project in Ybor City, for example, may require approval from:
- Barrio Latino Commission: Reviews all exterior alterations and new construction within the Ybor City Historic District
- Tampa Historic Preservation Commission: Reviews individually designated historic properties
- Florida Division of Historical Resources (SHPO): Reviews projects seeking federal historic tax credits
- National Park Service: Certifies federal tax credit applications
- City of Tampa Building Department: Reviews all projects for building code compliance
Each authority applies different standards and operates on different timelines. Coordinating approvals requires understanding each review process, anticipating potential conflicts between requirements, and sequencing applications appropriately. Our SHPO compliance services streamline this complex coordination.
Secretary of the Interior's Standards Compliance
Projects seeking federal historic tax credits must comply with the Secretary of the Interior's Standards for Rehabilitation—ten principles governing appropriate treatment of historic properties. These standards can conflict with owner preferences, modern building practices, and even local code requirements. Common compliance challenges include:
- Designing compatible additions that are differentiated from but don't detract from historic fabric
- Integrating modern mechanical systems without damaging character-defining features
- Balancing energy efficiency improvements with preservation of historic windows
- Finding code-compliant solutions for egress, accessibility, and life safety that preserve historic character
Building Code Compliance in Historic Structures
Historic buildings were constructed under building codes—or no codes at all—that differ dramatically from current requirements. The Florida Building Code provides some flexibility for historic structures through the Florida Building Code - Existing Building provisions, but achieving compliance often requires creative solutions. Common code challenges include:
- Means of egress: Historic buildings often have narrow stairs, limited exits, and corridor widths that don't meet current standards
- ADA accessibility: Integrating ramps, elevators, and accessible restrooms while preserving historic character
- Structural capacity: Historic floor systems may not meet current load requirements for proposed uses
- Fire protection: Sprinkler systems, fire-rated assemblies, and compartmentalization in buildings with exposed historic elements
Environmental and Hazardous Material Challenges
Asbestos-Containing Materials
Buildings constructed before 1980 commonly contain asbestos in insulation, flooring, roofing, plaster, and mechanical systems. Federal EPA regulations (40 CFR Part 61, Subpart M—the Asbestos NESHAP) and Florida Building Code Section 105.9 require asbestos surveys and proper abatement before renovation or demolition work. Key requirements include:
- Building permits must include an asbestos notification statement
- Licensed asbestos inspectors must survey the building before work begins
- Abatement must be performed by licensed asbestos contractors
- Proper notification to EPA and disposal at approved facilities
Lead-Based Paint
Virtually all buildings constructed before 1978 contain lead-based paint. EPA's Renovation, Repair, and Painting (RRP) Rule requires certified renovators and specific work practices when disturbing lead paint in pre-1978 buildings. Historic restoration projects must address lead paint on:
- Interior and exterior wood trim and millwork
- Window sashes and frames
- Doors and door frames
- Plaster walls and ceilings
- Metal components including radiators and piping
Other Environmental Concerns
Tampa's historic buildings may also present challenges from mold (particularly in Florida's humid climate), underground storage tanks, contaminated soil from historic industrial uses, and PCBs in older electrical equipment. Comprehensive environmental assessments early in the project help identify these issues before they become costly surprises.
Structural and Material Challenges
Hidden Structural Deficiencies
Historic buildings often conceal structural problems behind finished surfaces. Common issues discovered during restoration include:
- Termite damage: Tampa's climate makes wood structures particularly vulnerable to subterranean termites and drywood termites
- Foundation deterioration: Brick piers, rubble foundations, and early concrete may have deteriorated significantly
- Roof structure damage: Water infiltration, biological decay, and structural movement affect historic roof framing
- Masonry deterioration: Spalling brick, failed mortar joints, and corroded embedded metals in historic masonry walls
- Previous modifications: Structural elements removed or compromised by earlier renovations
Historic Material Sourcing
The Secretary of the Interior's Standards require replacing deteriorated historic materials with matching materials when repair is not feasible. Finding period-appropriate replacement materials presents significant challenges:
- Historic brick: Color, texture, and size variations require sourcing from salvage dealers or custom manufacturers
- Clay roof tiles: Spanish barrel tiles and other historic profiles may require specialized suppliers or custom production
- Heart pine lumber: Old-growth heart pine for structural and finish applications is increasingly scarce
- Historic window glass: Wavy glass, seeded glass, and other historic glazing types
- Decorative elements: Terra cotta ornament, cast stone details, and ornamental plaster
Our historic material sourcing services tap into networks of salvage dealers, specialty manufacturers, and craftspeople to locate or fabricate appropriate replacement materials.
Cost Considerations for Common Challenges
Understanding the cost implications of common challenges helps develop realistic budgets. The following table reflects typical Tampa-area costs for addressing these issues:
| Challenge | Typical Cost Range | Timeline Impact |
|---|---|---|
| Asbestos Survey & Testing | $3,000 - $15,000 | 2-4 weeks |
| Asbestos Abatement (per sq ft) | $15 - $50 | 2-8 weeks |
| Lead Paint Abatement (per sq ft) | $8 - $25 | 1-4 weeks |
| Structural Engineering Assessment | $5,000 - $25,000 | 2-6 weeks |
| Foundation Repair/Underpinning | $50,000 - $300,000 | 4-12 weeks |
| Historic Window Restoration (per window) | $800 - $2,500 | Varies |
| Custom Historic Brick Matching | $3 - $12 per brick | 8-16 weeks lead time |
| Tax Credit Application Management | $15,000 - $50,000 | 3-6 months review |
| Local Historic Commission Review | $500 - $5,000 (fees + documentation) | 1-3 months |
We recommend budgeting a 15-25% contingency for historic restoration projects to address unforeseen conditions discovered during construction. Projects with comprehensive pre-construction investigation typically experience fewer surprises and tighter contingency utilization.
Project Management Challenges
Scheduling Complexity
Historic restoration projects require longer schedules than comparable new construction due to:
- Extended regulatory review periods
- Specialized trade availability
- Long lead times for custom materials
- Methodical investigation and documentation requirements
- Weather sensitivity of certain restoration work
- Coordination with ongoing building operations (for occupied buildings)
Skilled Labor Availability
Quality historic restoration requires craftspeople with specialized skills that are increasingly rare. Finding qualified tradespeople for historic masonry, plasterwork, wood restoration, and other specialized disciplines requires maintaining strong relationships within the preservation community. Florida Construction Specialists has cultivated a network of skilled craftspeople experienced in traditional building methods.
Strategies for Overcoming Challenges
Successful historic restoration projects employ proactive strategies to identify and address challenges before they impact budget and schedule:
Invest in thorough assessment before design development to identify structural, environmental, and material conditions
Meet with review authorities during conceptual design to understand concerns and requirements before significant design investment
Sequence regulatory approvals to identify conflicts early and maintain project momentum
Assemble architects, engineers, and contractors with demonstrated historic preservation expertise
Budget realistically for unknowns with contingencies appropriate to building condition and scope
Identify specialty materials early and initiate procurement before construction begins
Frequently Asked Questions
How can I minimize surprises during historic restoration?
Invest in comprehensive pre-construction investigation including structural assessment, environmental surveys, and exploratory demolition in concealed areas. While this increases upfront costs, it reduces costly changes during construction and enables more accurate budgeting. Buildings with significant deferred maintenance or unknown construction history warrant more extensive investigation.
What if regulatory requirements conflict with each other?
Conflicts between building codes and preservation standards are common. The Florida Building Code - Existing Building provides flexibility for historic structures, and most preservation review authorities understand the need for code compliance. Working with authorities early to identify potential conflicts and develop acceptable solutions prevents delays. Documentation showing that preservation-sensitive alternatives were explored strengthens requests for code modifications.
How long should I expect a historic restoration project to take?
Most commercial historic restoration projects require 18-36 months from initial planning through completion. This includes 3-6 months for assessment and design, 3-6 months for regulatory approvals and permitting, and 12-24 months for construction. Projects seeking federal tax credits add 3-6 months for the Part 1/Part 2 application review process. Complex projects involving structural intervention or extensive environmental remediation may extend longer.
Is it worth pursuing federal historic tax credits given the complexity?
For qualified projects, the 20% federal tax credit can significantly offset the higher costs of historic restoration. The credit applies to qualified rehabilitation expenditures—not just the historic-specific work but most construction costs on certified rehabilitation projects. For a $2 million rehabilitation, the credit could exceed $400,000. Our team manages the application process to maximize credit value while minimizing administrative burden.
What happens if we discover issues after construction begins?
Discovery of unforeseen conditions during construction is common in historic restoration. Effective project management includes protocols for documenting conditions, evaluating options, and making timely decisions. For tax credit projects, significant scope changes require consultation with SHPO to ensure continued compliance. Adequate contingency budgeting provides financial flexibility to address discoveries without derailing the project.
