You've decided to renovate your property in Greece. You've got a rough idea of what you want to do. Maybe you've even spoken to a builder. And then someone mentions permits — and suddenly everything gets a lot more complicated.
Building permits in Greece are one of the most misunderstood parts of the renovation process for Greek-Australians and other diaspora owners. The system is genuinely complex, varies by location and property type, and is entirely in Greek. But it's not as impenetrable as it feels from the outside — especially with the right people helping you navigate it.
This guide explains what you need to know: which permits apply, how the process works, how long it takes, and how to manage it remotely from Australia.
Why Building Permits Matter More Than You Think
In Australia, you'd never start a renovation without checking whether a permit is required. In Greece, it's surprisingly common for work to begin — particularly on older family properties — without the right approvals in place.
The consequences can be serious:
Fines and mandatory demolition of unauthorised works
Legal complications when you try to sell the property
Ineligibility for government programmes like the Anakenizo 2026 renovation subsidy, which requires all works to be fully compliant
Insurance issues if something goes wrong during or after construction
Getting the permits right from the start isn't just bureaucracy — it protects your investment and keeps your options open.
Do You Always Need a Permit?
Not for every type of work. Greek law divides construction activity into categories, and smaller, cosmetic works can often proceed without a formal building permit.
Works that generally do NOT require a permit:
Interior painting and decorating
Minor repairs to existing fixtures
Replacement of flooring (like-for-like)
Small-scale plumbing repairs within existing systems
Works that DO require a permit or formal notification:
Any structural changes (walls, roof, foundations)
Extensions or additions to the building footprint
Changes to the external appearance of the property
Replacement of windows and doors (in some heritage areas)
Electrical rewiring and major plumbing alterations
Swimming pools
Any works on a listed or heritage building
The grey area: The Anakenizo 2026 renovation subsidy covers comprehensive renovation — kitchens, bathrooms, flooring, plumbing, electrical, structural improvements. Most of this work will require at minimum a formal notification to the authorities, and in many cases a full building permit. This is one of the reasons having a licensed Greek architect manage your application is not optional — it's mandatory under the programme.
The Three Categories of Building Permits
The Greek permit system organises works into three main categories:
Category 1 — Small-Scale Works (Notification Only)
Minor works that don't affect the structural integrity or external appearance of the building. You submit a notification (not a full application) to the local Urban Planning Authority. This is straightforward and can often be processed quickly.
Examples: minor internal alterations, small repairs, some types of flooring replacement.
Category 2 — Medium Works (Small-Scale Permit)
Works that affect the building more significantly but don't require a full architectural submission. Requires an engineer or architect to certify the work and submit documentation, but the approval process is faster than Category 3.
Examples: renovation of wet areas (kitchens, bathrooms), electrical rewiring, significant plumbing work.
Category 3 — Major Works (Full Building Permit)
Anything involving structural changes, extensions, or significant modifications to the building. This requires full architectural drawings, engineer's reports, and approval from the local Urban Planning Authority (Πολεοδομία). This is the most time-consuming category.
Examples: structural alterations, extensions, changes to the roofline, demolition of internal load-bearing walls.
Heritage Properties and Island Regulations
If your property is in a traditional settlement, a listed heritage area, or on one of the smaller Greek islands, there are additional layers of regulation to navigate.
Works on heritage-listed buildings must comply with strict guidelines set by the Ministry of Culture. Renovations must use traditional materials and methods — modern materials or techniques are not permitted in many cases. Any significant works may also require approval from the local Archaeological Authority, particularly if the area has known historical significance.
This is not unusual in the Greek diaspora context — many family properties on the islands or in traditional villages fall into this category. It doesn't mean you can't renovate; it means you need an architect who knows the local regulations and has relationships with the relevant authorities.
At PAREA, our team includes licensed architects with specific experience in heritage renovation across Athens and the islands. We know which authorities to engage, what they expect, and how to get approvals without unnecessary delays.
The Step-by-Step Permit Process
Here's how a typical building permit application works in Greece:
1. Engage a Licensed Architect All permit applications in Greece must be submitted by a licensed architect or engineer who is a member of the Technical Chamber of Greece (TEE). This isn't optional — you cannot submit an application yourself. Your architect is also legally responsible for ensuring the works comply with all applicable codes.
2. Prepare Architectural Drawings and Documentation Your architect prepares a full set of drawings showing the existing state of the property and the proposed works. For Category 3 permits, this includes structural engineer's reports, energy performance assessments, and supporting calculations.
3. Submit via the e-Adeies Platform Greece has digitised the permit submission process through the e-Adeies online platform (e-adeies.gov.gr). Your architect submits the application on your behalf electronically.
4. Authority Review The local Urban Planning Authority reviews the application. For Category 1 and 2 works, this can be relatively fast. For Category 3, review times vary significantly by local authority — in some areas, a few weeks; in others, several months.
5. Permit Issued Once approved, the permit is issued and works can begin. Your architect must be present at key construction milestones to certify compliance.
6. Completion Certificate When works are finished, your architect certifies completion and the property records are updated. This is a critical step — without a completion certificate, the works are not formally recognised.
How Long Does It Take?
The timeline depends on the category of works, the local authority, whether the property has any heritage status, and how complete and well-prepared your application is when it's submitted. A Category 1 notification might be processed in days. A full Category 3 permit in a busy municipality could take three to six months.
This is one of the most common sources of frustration for Greek-Australians managing renovations remotely. A project that should take three months can stretch to eight if the permit is delayed — and a builder sitting idle is a builder who finds other work.
The best mitigation is preparation: starting the permit process well before you want construction to begin, and working with an architect who knows the local authority and can proactively manage the process.
Permits and the Anakenizo 2026 Subsidy
If you're planning to apply for the Anakenizo 2026 renovation subsidy, permit compliance is non-negotiable. The programme requires all works to be properly authorised, and your application will need to be signed off by a licensed architect or engineer.
This is one of the reasons we recommend starting the permit and scoping process now — before the subsidy application platform opens in May 2026. Applications that are well-prepared, with a compliant scope of works and a licensed architect already engaged, will move through the process significantly faster than those that try to put everything together at the last minute.
Common Mistakes to Avoid
Starting work before permits are in place. It happens all the time, particularly when a trusted local builder says "don't worry, we don't need a permit for this." If something goes wrong — or if you later try to sell the property, or apply for a government programme — unauthorised works can be a very expensive problem.
Using an architect who isn't TEE-registered. All permit applications must be submitted by a TEE member. If your architect can't show you their TEE registration, they can't legally submit your application.
Underestimating heritage obligations. If your property is in a traditional settlement or listed area, the requirements are more demanding. Build extra time into your planning for heritage approvals.
Not accounting for permit timelines in your project schedule. If you want construction to start in June, your permit application should be in by February or March at the latest. Build the timeline backwards from when you want to be done.
