You cannot open a new café in the centre of Florence. Not because the rent is impossible, though it is, but because the comune has blocked it: since 2017 the city has used a heritage-protection power to stop new food and drink businesses opening inside the World Heritage site, and in April 2026 the council extended that block to 2031. The same boundary carries a second rule, no new short-term tourist lets, in force since 31 May 2025. Both apply to the 532 hectares inside the ring of avenues that follows the line of the fourteenth-century walls, which is very nearly the whole area a visitor pictures as Florence. Neither rule closes anything already trading, and neither restricts you as a visitor. What they change is what you find when you go looking for a room.
Where the UNESCO boundary runs
Florence's restrictions hang on a mapped line rather than a vague notion of the old town, and that line is easy to recognise on the ground. The inscribed property covers the area inside the circuit of avenues that corresponds to the ancient circle of the fourteenth-century walls, according to the Comune di Firenze's own World Heritage office (Ufficio Firenze Patrimonio Mondiale, The boundaries of the property, checked 15 September 2026). Those avenues are the viali di circonvallazione, laid out in the nineteenth century after the walls came down. If you are inside them, you are inside the World Heritage site.
UNESCO inscribed the Historic Centre of Florence in 1982 under criteria (i), (ii), (iii), (iv) and (vi), and records the property at 532 hectares with a buffer zone of 10,453 hectares (UNESCO World Heritage Centre, Historic Centre of Florence, checked 15 September 2026).
The buffer zone is not subject to the shop and letting rules described below. It is a landscape protection belt across the hills, and it governs what may be built and what views are protected, not what may open on a street in the centre.
The legal tool behind it
Italy gave its comuni a specific power to restrict business openings in heritage areas, and Florence was among the first to use it. Regione Toscana describes the instrument as one introduced by legislative decree 222 of 2016, under which a comune, acting in agreement with the region and having heard the competent superintendent of the culture ministry, may adopt resolutions delimiting zones of particular archaeological, historical, artistic and landscape value in which economic activities judged incompatible with heritage protection may be prohibited or made subject to authorisation (Toscana Notizie, Commercio, intesa Regione-Comune di Firenze a tutela centro storico, 29 March 2017, checked 15 September 2026).
The first Florentine application of that power was narrow and time-limited: a three-year prohibition on new food service openings in the historic centre. When the region and the comune renewed the agreement in 2020, the scope covered both new somministrazione di alimenti e bevande and new fixed-premises food retail, and it also blocked the transfer of existing businesses from outside into the UNESCO centre (Toscana Notizie, Commercio, Regione e Comune Firenze rinnovano accordo per tutela centro storico, 7 April 2020, checked 15 September 2026).
That last clause is the one that shapes the street. Without it a business could relocate in from the suburbs and the block would achieve nothing.
The rules now sit in a single municipal text, the Regolamento per la tutela e il decoro del patrimonio culturale del centro storico, whose Article 1 defines its area of application as the Centro Storico Patrimonio Mondiale UNESCO as drawn in the city's planning instruments (Comune di Firenze, regolamento text of December 2024, checked 15 September 2026). Florentines call it the Regolamento UNESCO.
What cannot open inside
Florence's Regolamento UNESCO works in two layers, and the difference between them decides whether a ban expires or does not. The table below compares the two mechanisms and what each one covers.
| Layer | What it covers | How long it lasts |
|---|---|---|
| Limitazioni con vincolo temporale | New food retail, food and drink service including home restaurants, food artisan production, bakeries, direct farm sales, cooking schools | Time-limited: three years in the 2024 text, five years in the 2026 text |
| Limitazioni senza vincolo temporale | Pizza-only sales, pre-cooked and frozen food preparation, food and drink vending machines, fast-food and self-service formats, nightclubs, money change and phone centres, ATMs, wholesale, compro-oro, betting shops, massage centres, unsupervised storage | Permanent, with no expiry date |
The permanent list is the more revealing of the two. It tells you what the comune considers corrosive to a heritage street: not restaurants as such, but the formats that scale fastest in a tourist district. Both lists sit in the regulation's Articles 2 and 4 (December 2024 and April 2026 texts, checked 15 September 2026).
In March 2026 the Giunta approved a five-year extension with new items attached, and the Consiglio comunale confirmed it on 13 April 2026, taking the block to 2031. The additions were cooking schools, a prohibition on new ATM devices outside commercial premises, and a rule blocking new premises for "consumo non assistito sul posto di prodotti alimentari, bevande comprese" where the usable floor area is under 100 square metres (Comune di Firenze, Giunta press release, 16 March 2026, and Consiglio press release, 13 April 2026, both checked 15 September 2026).
The seventy-one protected streets
A second, stricter regime applies inside Florence's centre to a named list of streets and squares rather than to the whole area. After the April 2026 extension the list runs to 71 streets, nine more than before, and includes Ponte Vecchio, via Tornabuoni, via Maggio and the main piazzas, among them San Giovanni, Duomo, Repubblica, Santa Croce and Signoria.
On those streets a new business must belong to a defined set of attività di pregio. The comune's own list names high fashion, prêt-à-porter and designer clothing retail, bookshops, art galleries and antique dealers, furniture and design, banks and insurance, precious objects, watches, art and antiques, numismatics and philately, traditional and artistic crafts, and retail of flowers and plants (Comune di Firenze, Consiglio press release, 13 April 2026, checked 15 September 2026).
The 2026 additions split into two kinds. Via dei Gondi, via Vacchereccia and Sdrucciolo dei Pitti join the prestige-only list; via Palazzuolo, Corso dei Tintori, Borgo dei Greci and via dei Benci become streets where an existing food licence may no longer be transferred in.
Two absences are worth stating. The Regolamento UNESCO does not cap prices, and it makes no judgement about quality. A shop can be permitted, protected and still sell you a mass-produced apron.
Short lets and the 2025 block
Florence's short-term rental restriction is a planning rule, not a commercial one, and it reached the statute book by a different route. In July 2024 the comune inserted a variant into the Piano Operativo that introduced "residenza temporanea" as a distinct use within residential use and prohibited that use from being newly established in the UNESCO historic nucleus (Comune di Firenze, Affitti turistici brevi, inserita nel Piano operativo la norma per il blocco in centro storico, 18 July 2024, checked 15 September 2026).
The operative instrument is the Regolamento per le Locazioni Turistiche Brevi, in force since 31 May 2025, which requires an authorisation from the comune for lets of up to 30 days and treats entrepreneurial lets as requiring a SCIA as well (Comune di Firenze SUAP, Locazioni turistiche brevi, checked 15 September 2026). Authorisations run for five years, the minimum dwelling size is 28 square metres, and operators outside the rules face fines of EUR 1,000 to EUR 10,000.
The comune widened the block on 4 June 2026. The table below sets out where new short-let authorisations are still possible.
| Area | New authorisations | Since |
|---|---|---|
| Sottozona A1, the UNESCO area, about 5.05 sq km | Blocked | 31 May 2025 |
| Sottozone A3 and A4, nine belt zones, about 11.21 sq km | Blocked | Approved 4 June 2026 |
| Remainder of the comune | Possible, subject to authorisation | — |
The nine belt zones are Campo di Marte, San Jacopino, Gavinana, Pignoncino e Paolo Uccello, Statuto e Rifredi, Libertà, Oberdan e Savonarola, Bronzino e Pier Vettori, and Fonderia e Petrarca.
What it means for booking
Your practical exposure to Florence's centre rules is narrow but real, and it concerns mainly where new supply appears. Florence counts 16,906 registered short-term letting activities, and the comune reports online listings rising from 10,867 in 2023 to 12,211 in 2026, roughly 85 per cent of them in the historic centre (same press release, 4 June 2026, checked 15 September 2026). The stock inside the walls stays large; what has stopped is its growth.
Because new authorisations inside the A1, A3 and A4 zones are closed, genuinely new apartment listings appear further out, beyond the belt zones. That is not a downgrade. Pressure on the centre is measurable: accommodation businesses recorded over 4.7 million arrivals and 11.5 million overnight stays in 2025, up 10.2 and 11.1 per cent on 2024.
Two things follow when you book. Treat a listing's distance from the viali as the useful measure rather than its distance from the Duomo, because the viali are where character and price change. And if a listing inside the centre looks unusually cheap for its address, ask the host for the authorisation: the regime has run since May 2025 and a compliant operator will have one.
The shop rules change what you will not see rather than what you will. New chain food formats, new vending-machine shops, new money-change counters and new ATMs outside shops are not arriving on these streets. Existing ones remain, so do not expect a centre swept clean.
What this guide does not cover
This guide covers the Comune di Firenze only, and only the two instruments named above. Neighbouring comuni in the buffer zone, including Fiesole, Sesto Fiorentino and Bagno a Ripoli, set their own commercial and letting rules, and nothing here describes them.
It does not cover Italy's national short-let framework, the CIN identification code, the tax treatment of a let or Florence's tourist tax. It also gives no legal advice to anyone planning to open a business or let a property; the regulation texts and the SUAP page are the documents to read, and both are linked above.
One caution about interpretation. The comune presents these measures as heritage management, and the site's own monitoring documents name the decline in resident numbers and the impact of mass tourism as threats to the property's integrity (Ufficio Firenze Patrimonio Mondiale, monitoring of the management plan, checked 15 September 2026), alongside a management plan approved in November 2022 with 30 projects and 171 indicators (Comune di Firenze, 4 November 2022, checked 15 September 2026). Whether the rules are working is a question those indicators are designed to answer over years, and no source consulted here claims an answer yet. Check the comune's press pages before assuming any of these dates still stand, because each has already been extended once.
