- Full permit review in Miami-Dade takes 4–12 weeks; total design-to-move-in timelines realistically run 6–14 months.
- Best for: Miami-Dade homeowners with pre-2000 homes in Coral Gables, Kendall, Coconut Grove, Homestead, or Hialeah planning a phased or gut renovation.
You're reading this because you're staring at a 1970s CBS home in Miami and wondering what a complete renovation will actually cost – not the national average, but the real number for your neighborhood, with your permits, in South Florida's climate. This guide reflects our team's research into Miami-Dade building requirements, local contractor market data, and verified cost sources. It was reviewed for accuracy against official county and state regulatory documents. According to gallerykbny.com, 93% of homeowners plan to hire professionals in 2026 – and in Miami, choosing the right one starts with understanding what you're actually buying.
What Does a Miami Whole Home Renovation Cost in 2026?
A Miami whole home renovation is a comprehensive upgrade of a residential property's systems, finishes, and structure – typically spanning kitchen, bathrooms, flooring, electrical, plumbing, HVAC, roofing, and windows in a single coordinated project. According to Sweeten, full home renovation in Miami starts at $100–$250+ per square foot, with Block Renovation confirming whole-home remodels in Miami commonly range $100–$250+ per square foot depending on scope and finishes.
| Finish Level | Cost/Sq Ft | 1,500 Sq Ft | 2,200 Sq Ft |
|---|---|---|---|
| Budget | $100–$150 | $150K–$225K | $220K–$330K |
| Mid-Range | $150–$220 | $225K–$330K | $330K–$484K |
| High-End | $220–$300 | $330K–$450K | $484K–$660K |
For a practical example: a 1,800 sq ft 1970s Miami home at mid-range ($175/sq ft) runs approximately $315,000 – but a budget-focused approach at $100/sq ft brings that same home to roughly $180,000, assuming cosmetic updates rather than full gut work.
Sweeten notes there's been a 20% increase in materials costs in recent years, which has pushed Miami budgets toward the upper end of national ranges. Block Renovation also flags that condos in Miami carry 20–40% higher per-square-foot rates than single-family homes due to building access restrictions and HOA requirements.
Miami-specific cost drivers you won't find in national guides: impact-resistant windows/doors (required under HVHZ code), hurricane straps, flood elevation compliance in FEMA AE/VE zones, and mold-resistant interior materials driven by South Florida's year-round humidity.
💡 Permit fees add 1–3% to total project cost. According to Block Renovation, Miami-Dade permit fees typically add $1,000–$10,000 to a project. On a $250,000 renovation, budget approximately $2,500–$4,500 in permit costs alone, before sub-permit fees for electrical, plumbing, and mechanical work.
For a deeper look at complete home remodeling in Miami, the scope and sequencing decisions are covered in detail in our complete home remodeling in Miami guide.
Key Takeaway: Miami whole home renovation costs $100–$300/sq ft. A 1,800 sq ft mid-range project runs $270K–$396K. Budget an additional $1,000–$10,000 for Miami-Dade permits and factor in mandatory hurricane-code upgrades not reflected in national cost averages.
How Do You Plan a Whole Home Renovation in Miami?
Effective planning for a Miami whole home remodel follows a four-step sequence: assess → budget → permit → phase. Skipping the assessment step is the most common reason projects run over budget here in Miami, because pre-1980 CBS homes routinely reveal aluminum branch wiring, galvanized pipes, and non-hurricane-compliant roof connections once walls open up.
Miami-specific pre-renovation checklist:
- Mold inspection (critical in South Florida's humidity)
- Roof age and compliance with current FBC HVHZ requirements
- Plumbing material – galvanized steel or polybutylene (gray plastic, common 1978–1995) both require full replacement
- Electrical panel and branch circuit type – aluminum wiring in 1960s–1970s homes requires remediation
- FEMA flood zone status – properties in AE/VE zones face the 50% rule (renovation costs exceeding 50% of pre-improvement market value trigger full elevation compliance)
- HOA or historic district restrictions (especially relevant in Coral Gables and Coconut Grove)
Prioritize structural and code upgrades before cosmetic finishes. A new kitchen looks great until a failed inspection forces drywall removal to address unpermitted electrical work behind it.
Gut Renovation vs. Phased Approach: Which Is Right for You?
A gut renovation – stripping to the studs and rebuilding – makes sense when a home has multiple failing systems, significant mold, or requires full hurricane-code compliance. The cost efficiency of doing everything at once (one mobilization, one permit, one contractor) typically outweighs the higher upfront investment for homes with 3+ major system failures.
A phased approach works better when budget constraints are real, the home is livable, and systems are failing independently rather than simultaneously. Homeowners in Kendall and Hialeah with structurally sound CBS homes often phase kitchen and bathroom renovations over 2–3 years while deferring roof and window upgrades to a later phase.
Decision framework:
| Scenario | Recommended Approach |
|---|---|
| 3+ failing systems, pre-1980 home | Gut renovation |
| Livable home, 1–2 systems failing | Phased renovation |
| Flood zone property near 50% threshold | Gut renovation (control the trigger) |
| Historic district (Coral Gables) | Phased with ARB pre-approval |
| Budget under $150K | Phased, prioritize structural first |
For complete home remodeling in Coral Gables, the Architectural Review Board adds a pre-permit approval step that affects both timeline and material choices – plan for an additional 4–8 weeks minimum.
Key Takeaway: Start with a professional assessment of mechanical systems, roof, and plumbing before finalizing any budget. Miami's pre-1980 housing stock regularly surfaces $20,000–$50,000 in mandatory remediation items that gut renovations absorb more efficiently than phased projects.
Miami-Dade Permits for Whole Home Renovations
A building permit in Miami-Dade is required for any work affecting structural elements, electrical systems, plumbing, HVAC, roofing, or window/door replacements. According to Permitflow, structural and major alterations requiring a permit include new construction, additions, enclosing patios or balconies, and any work on load-bearing elements.
What triggers a permit vs. what doesn't:
| Scope | Permit Required? |
|---|---|
| Full gut renovation | Yes – building + MEP sub-permits |
| Window/door replacement | Yes – NOA product approval required |
| Roof replacement | Yes – HVHZ compliance inspection |
| Cosmetic paint/flooring | No |
| Cabinet replacement (no plumbing move) | No |
| Electrical panel upgrade | Yes |
According to Miami-Dade County Building Department, full residential renovation permits are processed through the county's ePermits portal, with plan review typically taking 4–12 weeks. Complex structural scopes or properties in historic districts can exceed 12 weeks. According to Falke Corp, administrative friction in the permitting phase accounts for an average of 14% of total pre-construction cost overruns – a significant risk for homeowners who don't build permit timelines into their project schedules.
Permit fee ranges (Home Briefings):
- Small bathroom updates: $250–$600
- Kitchen remodels: $500–$1,200
- Additions/major structural: $1,500+
- Electrical/plumbing sub-permits: $150–$400 each
Note: Miami-Dade County implemented a revised fee schedule effective October 1, 2025 – the first increase in more than 17 years. Obtain a current fee estimate from the MDBC portal before finalizing your budget.
⚠️ Warning: According to MySitePlan, the penalty for not pulling a permit in Florida can reach $5,000 per day. Unpermitted work also risks insurance denial, forced removal at the homeowner's expense, and complications at resale.
For a step-by-step walkthrough of the Miami-Dade building permit process process, the Home Briefings permit guide covers application sequencing in detail.
Key Takeaway: Budget 4–12 weeks for permit review in Miami-Dade and add $1,500–$5,000+ in permit fees for a full renovation. The October 2025 fee schedule increase makes early budgeting essential – get a fee estimate before signing a contractor agreement.
Room-by-Room Cost Breakdown for Miami Whole Home Renovations
Understanding individual room costs helps Miami homeowners build accurate phase budgets and evaluate contractor quotes. The figures below reflect South Florida market pricing, including the material and labor premiums driven by HVHZ requirements and humidity-resistant specifications.
| Scope | Low | Mid | High |
|---|---|---|---|
| Kitchen remodel | $25,000 | $50,000 | $85,000+ |
| Bathroom remodel (per bath) | $8,000 | $25,000 | $45,000 |
| Flooring (per sq ft installed) | $6 | $12 | $18 |
| Impact windows/doors (per opening) | $800 | $1,200 | $1,800 |
| Roof replacement | $12,000 | $22,000 | $35,000 |
| Electrical panel upgrade | $2,500 | $4,000 | $6,000 |
| HVAC replacement | $6,000 | $10,000 | $14,000 |
According to Block Renovation, Miami kitchen remodels run $25,000 for basic updates to $80,000+ for high-end spaces, while bathroom remodels start around $15,000 with primary baths landing between $28,000 and $55,000. For detailed breakdowns, see our guides on Miami kitchen remodeling costs and Miami bathroom remodeling costs Miami kitchen remodeling and Miami bathroom remodeling.
South Florida's humidity adds a material premium across interior scopes. Mold-resistant drywall and primer add approximately 8–15% to interior wall costs versus standard drywall – a whole-home consideration in Miami's climate, not just wet areas.
Many 1950s–1970s Miami homes also feature original terrazzo floors. Restoration (grinding, polishing, sealing) runs $3–$8/sq ft and is typically more cost-effective than replacement, which adds $6–$18/sq ft for new flooring over the existing mortar bed.
Hurricane-Code Upgrades: What Miami Homeowners Must Budget For
Miami-Dade sits in Florida's High-Velocity Hurricane Zone (HVHZ), the most stringent wind-resistance designation in the country. Any permitted renovation that touches roofing, windows, or structural elements triggers HVHZ compliance requirements – these are not optional upgrades.
Mandatory HVHZ line items for a full renovation:
- Impact windows/doors: 12 openings × $1,200 avg = $14,400 (required for full renovation permit; all products must carry a Miami-Dade Notice of Acceptance)
- Hurricane straps/clips: $1,500–$4,500 for a typical single-family home, triggered when a re-roofing permit is pulled
- FBC-compliant roofing system: $12,000–$35,000 for HVHZ-approved tile, metal, or shingle
For homeowners in Homestead, Kendall, or Miami Beach planning complete home remodeling in Kendall or surrounding areas, these hurricane-code costs are non-negotiable budget items – not upgrades to consider later.
Key Takeaway: A 12-opening impact window upgrade alone runs ~$14,400 at Miami market rates. Combined with hurricane straps and HVHZ roofing, mandatory code upgrades can add $30,000–$55,000 to a full renovation budget before a single cosmetic finish is selected.
How to Choose a Whole Home Renovation Contractor in Miami
Selecting a qualified contractor for a Miami whole home remodel requires verifying credentials at both the state and county level – a dual requirement that catches many homeowners off guard. According to Florida DBPR, all general contractors must hold a Florida CGC (Certified General Contractor), CBC (Certified Building Contractor), or CRC (Certified Residential Contractor) license, verifiable at myfloridalicense.com.
Miami-Dade adds a second layer: trade contractors performing electrical, plumbing, and mechanical work must hold both a Florida state license and a Miami-Dade County Certificate of Competency. A contractor whose subs lack county competency cards cannot legally pull MEP permits in Miami-Dade – a red flag that surfaces during inspections, not before.
5 red flags to screen for before signing:
- Refuses to pull permits or suggests "working without" to save time
- Demands more than 10% upfront without immediate permit activity (see Florida Statute 489.126)
- No written contract with itemized scope of work
- Cannot provide proof of general liability and workers' comp insurance
- Unfamiliar with Miami-Dade wind-load requirements or NOA product approval process
Quote comparison framework – ask every bidder for:
- Itemized scope of work (not lump sum)
- Specific product specifications (impact window brand/model with NOA number)
- Payment schedule tied to milestones, not calendar dates
- Three Miami-area references on projects completed in the last 18 months
Fab's Construction & Remodeling is a Miami-Dade licensed contractor serving homeowners across the county, including projects in Coral Gables, Coconut Grove, and Pinecrest. When evaluating any contractor, confirm their CGC or CBC license number through DBPR and verify their familiarity with HVHZ requirements before requesting a bid.
For complete home remodeling in Pinecrest and complete home remodeling in Coconut Grove, where older homes and HOA restrictions add complexity, contractor experience with local permitting offices matters as much as price.
Key Takeaway: Verify Florida CGC/CBC license via DBPR and confirm Miami-Dade County competency cards for all trade subs. Contractors unfamiliar with HVHZ requirements or NOA product approvals are a liability risk on any permitted Miami renovation.
What Is the Realistic Timeline for a Miami Whole Home Renovation?
A complete Miami whole home renovation realistically spans 6–14 months 6–14 months from design kickoff to move-back-in, once Miami-Dade permit review timelines, inspector availability, and hurricane-season supply chain factors are included.
| Phase | Duration |
|---|---|
| Design & drawings | 4–8 weeks |
| Permitting (plan review) | 4–12 weeks |
| Demolition | 1–2 weeks |
| Rough-ins (electrical, plumbing, HVAC) | 4–6 weeks |
| Inspections & approvals | 1–3 weeks |
| Finishes (drywall, flooring, cabinets, tile) | 6–10 weeks |
| Total | 20–41 weeks (5–10 months active construction) |
A practical example: design started in January, permits pulled in March, construction underway by April, with a realistic move-back-in target of October for a 2,200 sq ft home – assuming no major inspection delays or material backorders.
According to Falke Corp, a delay of 90 days in the current economic climate can reduce total project ROI by 7% or more – making early permit submission a financial priority, not just a scheduling one.
Miami-specific delay factors to plan for:
- Inspector availability (Miami-Dade inspection queues run 1–2 weeks during peak periods)
- Hurricane season (June–November) supply chain disruptions for roofing and windows
- HOA approval processes in Doral, Kendall, and gated communities
- Coral Gables ARB review cycles (monthly meetings; a missed cycle adds 4–6 weeks)
💡 Tip: Start design and permit drawings before finalizing all material selections. Submitting permit documents early – even with some finish selections pending – can save 4–6 weeks of total project time.
Key Takeaway: Plan for 6–14 months total for a Miami whole home renovation. Submit permit applications as early as possible – Miami-Dade's 4–12 week review window is the single largest controllable delay in the entire project timeline.

Do I need permits for a whole home renovation in Miami-Dade?
Direct Answer: Yes. Any work affecting structural elements, electrical, plumbing, HVAC, roofing, or windows requires a building permit in Miami-Dade County.
According to MySitePlan, the penalty for unpermitted work in Florida can reach $5,000 per day. Unpermitted renovations also risk insurance denial and forced removal of completed work. All permits are processed through Miami-Dade's ePermits portal.
How long does a whole home renovation take in Miami?
Direct Answer: A complete Miami whole home renovation realistically takes 6–14 months from design start to move-back-in, including 4–12 weeks for Miami-Dade permit review alone.
The longest single delay factor is permit plan review. According to Falke Corp, a 90-day permit delay can reduce project ROI by 7% or more. Starting design and permit drawings simultaneously is the most effective way to compress the overall timeline.
Is it cheaper to renovate or buy a new home in Miami?
Direct Answer: For most Miami homeowners, renovating an existing home is more cost-effective than purchasing a comparable move-in-ready property, particularly given Miami's current real estate market conditions.
Approximately 54% of renovation costs are recouped in added home value. gallerykbny.com notes that nearly 79% of homeowners report wanting to stay in their current home rather than move – a preference that renovation supports directly.
Can I live in my home during a whole home renovation in Miami?
Direct Answer: Living in your home during a full gut renovation is generally not practical or safe; phased renovations that isolate active construction zones can allow partial occupancy.
During demolition, rough-in work, and active electrical or plumbing phases, dust, noise, utility interruptions, and open walls make occupancy impractical. For phased projects – for example, renovating one bathroom at a time – temporary occupancy is feasible with proper dust containment and contractor scheduling.
What should I renovate first in a Miami whole home remodel?
Direct Answer: Prioritize structural and code-required upgrades first – see our guide on what to renovate first in your home – roof, electrical, plumbing, and hurricane-code compliance – before any cosmetic work.
Opening walls for cosmetic finishes before addressing failing systems means doing the same work twice. In Miami specifically, mold remediation, galvanized pipe replacement, and HVHZ window upgrades should all precede kitchen or bathroom cosmetic renovations. For a detailed sequencing framework, see our guide on complete home remodeling in Miami.
How do I find a licensed whole home renovation contractor in Miami?
Direct Answer: Verify Florida CGC or CBC license status at myfloridalicense.com and confirm Miami-Dade County competency cards for all trade subcontractors before signing any contract.
According to Florida DBPR, all general contractors must hold a state-issued CGC, CBC, or CRC license. Miami-Dade additionally requires county-level competency cards for electrical, plumbing, and mechanical trades – a dual requirement unique to this market. Ask for three local references on projects completed within the last 18 months and confirm the contractor pulls all permits in their own name.
