Renovating an Apartment in Florence: Costs, UNESCO Restrictions and Appreciation Potential

Leopoldo Manini - Founder MANINI® — 20 April 2026 — 20 min read

Introduction

Renovating an apartment in Florence is a very different operation from renovating a farmhouse in the countryside. The historic centre is entirely protected, condominiums add complexity, spaces are reduced and costs per square metre are among the highest in Tuscany. But the appreciation potential is enormous.

Florence is the Italian city with the highest property value per square metre after Milan and Rome. A quality-renovated apartment in the historic centre can be worth €6,000-€12,000/sqm, compared to €3,000-€5,000/sqm for an unrenovated apartment. The difference is the intervention margin.

Specific Restrictions in Florence's Historic Centre

The Monumental Protection

Florence's entire historic centre is a UNESCO World Heritage Site. This means:

• No external modifications: no work on facades, windows, entrance doors, eaves without Soprintendenza authorisation
• Mandated materials: wooden frames (no aluminium, no PVC), Florentine-style shutters, lime plaster, pietra serena for thresholds and windowsills
• Regulated colours: Florence Municipality has a colour chart for permitted facade and frame colours
• External systems prohibited: no visible external air conditioning units from the street, no antennas, no exposed cables

Condominium Regulations

Unlike an isolated farmhouse, a condominium apartment has additional constraints:

• Construction hours: generally 8:00-13:00 and 14:30-18:00, Saturday mornings only
• Noisy work restrictions: in some condominiums limited to 2-3 hours/day
• Staircase and lift access: regulated for material transport
• Common areas: any work on load-bearing walls, columns, floors requires assembly approval
• Damage liability: mandatory site insurance for third-party damage

The ZTL and Logistics

Florence's historic centre is a ZTL (Limited Traffic Zone). This enormously impacts site logistics:

• ZTL permits: required for every construction vehicle, cost €50-€150/day per vehicle
• Loading/unloading hours: limited to 6:00-9:30 and 19:00-22:00
• Public land occupation: for scaffolding or containers, municipal permit (€500-€3,000/month)
• Vehicle parking: often impossible near the site, material shuttle costs

These logistical constraints can increase costs by 15-25% compared to a site outside the ZTL.

Realistic Timelines

| Intervention type | Design | Permits | Construction | Total |

|------------------|--------|---------|--------------|-------|

| Restyling | 1-2 months | 1-2 months | 2-3 months | 4-7 months |

| Complete | 2-3 months | 2-4 months | 3-5 months | 7-12 months |

| Premium | 3-6 months | 3-6 months | 5-8 months | 11-20 months |

Florence-Specific Renovation Mistakes

1. Not verifying planning compliance before purchase

In Florence, many apartments have cadastral or planning discrepancies (moved partition walls, unauthorised mezzanines, modified windows). Without compliance, you cannot obtain permits for new works.

2. Underestimating frame costs

The mandatory wooden frames in the historic centre cost 3-4 times PVC ones. For an apartment with 8-10 windows, the difference is €15,000-€25,000.

3. Not considering acoustics

Historic Florentine buildings have wooden floors with poor sound insulation. An acoustic decoupling intervention (floating floor + false ceiling) costs €80-€120/sqm but is essential for liveability.

4. Ignoring the damp problem

Ground floors and basements of Florentine buildings suffer from rising damp. Without specific intervention (chemical cut, ventilated crawl space), any renovation will deteriorate.

5. Not coordinating with the condominium

Works affecting common parts (drains, risers, load-bearing walls) require assembly approval. If not obtained before starting works, the site stops.

Appreciation Potential

Florence offers significant appreciation margins:

• Oltrarno: purchase €4,000-€5,500/sqm → post-renovation €7,000-€9,000/sqm
• Santa Croce: purchase €4,500-€6,000/sqm → post-renovation €8,000-€11,000/sqm
• Centre (Duomo, Signoria): purchase €6,000-€8,000/sqm → post-renovation €10,000-€14,000/sqm

For an 80 sqm apartment in Oltrarno: purchase €400,000 + renovation €150,000 = €550,000. Post-intervention value: €640,000-€720,000. Gross margin: €90,000-€170,000.

Holiday vs Residential Rental

In Florence, holiday rental is regulated but still very profitable:

• Holiday rental (centre): €150-€350/night, 70-80% occupancy = €38,000-€80,000/year gross
• Residential rental (centre): €1,200-€2,500/month = €14,400-€30,000/year
• Flat tax (cedolare secca turistica): 21%

Note: since 2024, Florence Municipality has introduced restrictions on new tourist licences in the historic centre. Verify feasibility before purchase.

Conclusion

Renovating an apartment in Florence requires specific expertise: knowledge of UNESCO restrictions, ZTL logistics management, relationships with Soprintendenza and condominium, and the ability to work in reduced spaces with high standards. Costs are higher than in the countryside, but the appreciation potential is proportionally greater.
