Add-A-Level in Jacksonville

Local Expertise in Jacksonville, Duval County

Jacksonville spans historic riverfront districts, mid-century suburbs, and new infill across both sides of the St. Johns River. From the bungalows of Riverside and Avondale to the ranch homes of Arlington and Ortega, each part of the city brings its own structural quirks, lot constraints, and permitting history. We build across all of Duval County.

Areas We Serve in Jacksonville

  • Riverside
  • Avondale
  • San Marco
  • Ortega
  • Springfield
  • Arlington

Building Conditions & Permitting

Older Jacksonville neighborhoods like Springfield and Avondale carry historic-district overlays and aging framing that often need bringing up to current code during a renovation. We assess existing structure, knob-and-tube or undersized service, and foundation settling before scoping the work — no surprises mid-project.

Common Questions

Add-A-Level in Jacksonville — FAQs

How much does add-a-level cost in Jacksonville, FL?
Costs vary by project scope, materials, and site conditions in Jacksonville. Blue Diamond provides detailed written estimates after a site visit — no ballpark figures. Call (813) 587-0368 to schedule your free Jacksonville consultation.
Can you work on historic homes in Riverside or Springfield?
Yes. We routinely renovate historic Jacksonville homes and understand the historic-district review process. We preserve original character where required while upgrading structure, electrical, and envelope to current Duval County code.
How long does permitting take in the City of Jacksonville?
Standard residential permits in Duval County typically take 4–8 weeks depending on scope and whether historic or zoning review applies. We submit complete packages up front to avoid back-and-forth that drags out review.
What is included in the Add-A-Level package?
Our standard package for a 1,500 SF home includes 3 bedrooms and a full bathroom on a new second floor, starting at $99,000. This covers structural engineering, permits, framing, roofing integration, electrical, plumbing, HVAC extension, insulation, drywall, windows, doors, and interior finish work.
Is my home structurally capable of supporting a second story?
Most single-story homes in Northeast Florida can support a second story with appropriate structural engineering. We review your existing foundation, framing, and bearing walls as part of our assessment. If the foundation needs reinforcement, we identify it upfront and include the cost — no surprises.
How long does an Add-A-Level take from start to finish?
An Add-A-Level project typically takes 6–10 months from contract to certificate of occupancy: 2–4 months for engineering and permitting, 4–6 months for construction. We provide a full schedule at contract and update you at every phase.
Why does an Add-A-Level require a CGC license?
Structural additions require a Certified General Contractor (CGC) license in Florida — the highest level. A CGC oversees structural engineering, pulls all permits, coordinates all licensed trades, and takes full project responsibility. Specialty and subcontractor licenses are not sufficient for second-story structural additions.
