Renovating an Old House in Italy: Costs, Timeline, and the Paperwork Part
The honest costs, timeline, and bureaucracy of renovating an old house in Italy — permits, the geometra, the surprises behind the plaster, and what to budget before you start.
Renovating an old house in Italy is two projects at once: the one you can see — stone, plaster, light — and the one you can't — permits, certificates, and the slow machinery of the comune. Fall in love with the first and forget the second, and the house will teach you the difference the expensive way. This is the field note I wish I'd had before I started imagining what I'd do with a wreck in the centro storico.
I'm still deciding whether to take one on myself. But I've learned enough — and lost enough — to tell you how the real version works.
What to know first: nothing happens without permits
Even “just” renovating usually means filing with the comune through a geometra or architect — a CILA or SCIA for most works, a full permesso di costruire for bigger structural or volume changes. Historic centers add a layer: the Soprintendenza (heritage authority) can weigh in on what you touch, from windows to roof tiles to the color of your shutters. Beautiful constraints, but constraints.
The real-life version: the surprises behind the plaster
Old Italian houses keep their secrets in the walls — damp, ancient wiring, a beam that's more history than structure, a “small” layout change that turns out to need permits. Budget for discovery. The first wall you open will tell you how honest the rest of the renovation is going to be.
Costs and timeline, roughly
| Phase | What it involves | Reality check |
|---|---|---|
| Due diligence | Geometra, permits check, surveys | Do this before you buy |
| Design + permits | Drawings, comune filings, heritage sign-off | Months, not weeks |
| Build | Structure, systems, finishes | Always longer than quoted |
| Contingency | The surprises behind the plaster | Budget 15–20% on top |
Costs swing widely by region, condition, and ambition. The honest rule: take your first number, add the contingency, then add time. An old house is not a fast project.
What I'd do differently
- Get the geometra and a permits check before buying, not after. (Ask me how I learned this, or read How We Lost Our House.)
- Confirm what the Soprintendenza controls before you plan a single change.
- Build a real contingency into the budget and the timeline. Then add a little more.
- Hire local trades through people who've actually used them.
Common mistakes to avoid
- Assuming a renovation is simpler than a build. The paperwork can be just as involved.
- Starting work before permits are approved — an abuso you create is one you'll pay to fix.
- Budgeting only for what you can see.
Frequently asked questions
Do I need a permit to renovate a house in Italy?
Almost always — usually filed via a geometra or architect (CILA/SCIA), with a full building permit for structural or volume changes. Historic centers add heritage approval.
What is the Soprintendenza?
The heritage authority that oversees changes to protected and historic buildings. In a centro storico, they may weigh in on materials, windows, roofs, and more.
How much does it cost to renovate a house in Italy?
It varies enormously by region and condition. Whatever your first estimate, add a 15–20% contingency and extra time for the surprises old houses always hold.
How long does an Italian renovation take?
Design and permits alone can take months. The build is almost always longer than quoted. Plan for patience as a line item.
Should I buy a wreck or a finished house?
A wreck can be the most honest, rewarding project there is — if you go in with permits checked, a contingency budgeted, and your romance balanced by paperwork.
