Home renovation in St. Augustine, FL is one of the most rewarding investments a homeowner can make — and one of the most complicated if you choose the wrong approach. St. Augustine sits in one of the fastest-growing corridors in Northeast Florida, and with that growth comes a real estate market that rewards well-executed, quality renovations. Whether you are updating a 1980s ranch home in Fruit Cove, expanding a townhouse in Nocatee, or overhauling the kitchen of a historic property near the old city, the fundamentals of a successful renovation project are the same.
This guide covers what you need to know: project types, realistic costs, what sets the design-build model apart from traditional remodeling, permitting requirements in St. Johns County, and how to evaluate a contractor before you sign anything.

What Is Design-Build Home Renovation?
The design-build model puts your architect and your builder under one roof, with one contract and one point of accountability. Traditional remodeling splits the job: you hire a designer or architect separately, receive drawings, solicit bids from contractors, and then coordinate between them throughout construction. That gap — between what the designer drew and what the contractor actually builds — is where most renovation projects go sideways.
With a design-build firm like Wilson & Co, the same team that creates your design executes the construction. There is no handoff, no blame-shifting, and no budget surprises that show up when a contractor reprices plans they had no hand in creating. For homeowners in St. Augustine undertaking kitchens, bathrooms, additions, or whole-home remodels, this structure is a significant advantage.

Most Popular Home Renovation Projects in St. Augustine, FL
Kitchen Remodeling
Kitchen renovations consistently top the list of requested projects in Northeast Florida. The combination of open-concept living demand, aging builder-grade cabinetry in 15–25-year-old homes, and the genuine impact on daily quality of life makes kitchen remodels a priority for most homeowners.
A mid-range kitchen renovation in St. Augustine — new cabinetry, quartz countertops, appliance upgrades, updated lighting, and tile backsplash — typically runs $50,000–$80,000. Full gut renovations with layout changes, island additions, or premium finishes from brands like Sub-Zero or Wolf can exceed $100,000.
The return on a well-executed kitchen renovation in this market is strong: quality kitchens routinely return 70–80% of their cost at resale, and in a competitive listing environment, an updated kitchen can shorten time on market considerably.
Bathroom Remodeling
Florida bathrooms work harder than in most states. Humidity, hard water, and heavy daily use expose cheap materials fast. A proper bathroom renovation in St. Augustine needs to account for climate-appropriate waterproofing, ventilation, and durable tile and fixture choices built for the environment.
Common scopes:
- • Guest bath refresh: $15,000–$25,000 (new vanity, tile, fixtures, lighting)
- • Master bathroom remodel: $30,000–$55,000 (new shower, soaking tub, double vanity, heated tile floors)
- • Luxury master bath: $60,000–$90,000+ (frameless glass, custom tile work, freestanding tub, specialty lighting)
Home Additions
For homeowners who love their location but need more space, a home addition is often the most cost-effective path. Moving in Northeast Florida means leaving a favorable mortgage rate, absorbing transaction costs, and competing in a tight inventory market. An addition eliminates all of that.
Popular addition types in St. Augustine:
| Addition Type | Typical Cost | Timeline | |---|---|---| | Florida Room (screened) | $20,000–$45,000 | 2–3 months | | Florida Room (enclosed) | $50,000–$120,000 | 3–4 months | | Master Suite Addition | $100,000–$225,000 | 4–6 months | | In-Law Suite / ADU | $90,000–$210,000 | 4–7 months | | Second Story Addition | $200,000–$500,000+ | 6–10 months |
All home additions in St. Johns County require a building permit and must comply with Florida's wind-load codes, including hurricane strap requirements for all roof framing connections. We manage the full permitting process as part of every project. For a detailed breakdown of timelines and what happens during each phase, see our home addition process guide.
Custom Interiors and Built-Ins
Not every renovation requires moving walls. Custom built-ins — walk-in closet systems, home office cabinetry, entertainment walls, mudroom organizers, decorative ceiling beams — transform how a home feels and functions without the timeline or cost of structural work. These projects also add meaningful value for buyers who recognize quality craftsmanship.

How Much Does Home Renovation Cost in St. Augustine, FL?
Cost varies by project type, scope, and finish level. The table below provides general ranges based on local project data for Northeast Florida.
| Project Type | Budget Range | Mid-Range | Premium | |---|---|---|---| | Kitchen Remodel | $35,000–$50,000 | $55,000–$85,000 | $90,000–$150,000+ | | Bathroom Remodel | $15,000–$28,000 | $30,000–$55,000 | $60,000–$100,000+ | | Room Addition (per sq ft) | $200–$250 | $255–$325 | $330–$400+ | | Custom Built-Ins | $5,000–$12,000 | $13,000–$25,000 | $25,000–$50,000+ | | Whole-Home Remodel | $150,000–$250,000 | $260,000–$450,000 | $450,000+ |
Costs include design, permitting, labor, and standard materials. Structural upgrades, foundation work, flood zone compliance, and premium material selections increase the total.
What Drives Costs Up in Northeast Florida?
Florida building code requirements. Wind-load compliance, hurricane straps, impact-resistant windows and doors, and elevated foundation requirements in flood zones all add cost compared to non-hurricane-zone construction. These are not optional — they protect your home and your insurance coverage.
Permitting timelines. St. Johns County is one of the busiest permit markets in Florida. Plan review and approval for a substantial renovation can take 4–8 weeks. Contractors who promise to "start Monday" without a pulled permit are a red flag — unpermitted work can create serious problems at resale and may void your homeowner's insurance for covered losses.
Materials. Northeast Florida does not have the same supplier concentration as Orlando or Tampa. Specialty materials sometimes carry longer lead times, which a well-organized design-build firm accounts for in the project schedule up front.

Choosing a Home Renovation Contractor in St. Augustine
The St. Augustine market has no shortage of contractors. Here is what to verify before signing:
- • Active Florida CGC or CBC license — Verify at the Department of Business and Professional Regulation (DBPR) website
- • General liability and workers' compensation insurance — Get the certificates, not just a verbal assurance
- • Permit history — A legitimate contractor pulls permits for every project; ask for examples
- • Written contract with detailed scope — Avoid contractors who operate on verbal agreements or vague "allowances"
- • Local references — Ask to see a recently completed local project, not just photos

Home Renovation and Property Value in St. Augustine
St. Augustine's real estate market has performed well over the past decade, driven by proximity to Jacksonville's employment base, quality St. Johns County schools, and the consistent appeal of coastal Northeast Florida living. Renovation ROI here compares favorably with state averages:
| Project | Average Cost (NE FL) | Average Value Added | ROI | |---|---|---|---| | Kitchen Remodel (mid-range) | $65,000 | $48,000–$55,000 | 74–85% | | Bathroom Remodel (master) | $42,000 | $27,000–$32,000 | 64–76% | | Home Addition (master suite) | $160,000 | $80,000–$110,000 | 50–69% | | Curb Appeal / Exterior | $18,000 | $14,000–$17,000 | 78–94% |
These figures represent cost recoup at resale. The lifestyle value of living in a renovated, well-designed home during the years you own it is separate from the resale calculation — and for most homeowners, that is the more meaningful number.

FAQ: Home Renovation in St. Augustine, FL
How long does a home renovation take in St. Augustine? Timeline depends heavily on scope. A kitchen or bathroom remodel typically takes 6–12 weeks of active construction, plus 4–8 weeks of permitting before work begins. Home additions run 4–10 months from design to completion. We provide a specific project schedule during the planning phase so you can set realistic expectations.
Do I need a permit for a home renovation in St. Johns County? Yes. Any renovation involving structural changes, electrical, plumbing, or HVAC work requires a building permit through St. Johns County Building Services. Cosmetic work — paint, flooring, cabinet hardware — generally does not. Wilson & Co handles all permitting for every project we build.
Can I live in my home during a renovation? For most projects, yes. Kitchens and bathrooms are temporarily out of service during active construction, but we create temporary solutions and sequence work to maintain livable conditions. For whole-home remodels or major structural additions, partial or temporary relocation may be necessary during certain phases.
What is the difference between a general contractor and a design-build firm? A general contractor builds from plans provided by someone else. A design-build firm creates both the design and executes the construction under one contract. The design-build model reduces handoff errors, shortens the overall project timeline, and provides a single point of accountability for the entire project.
How do I get started with Wilson & Co Design Build? The process begins with a free consultation at your home. We discuss your goals, evaluate the existing space, and provide an honest assessment of what is achievable within your budget. There is no obligation and no pressure — we want to make sure it is the right fit before either of us commits to anything.
