Renovating a Greek property from abroad.

Few things go wrong faster in diaspora property ownership than a renovation managed by WhatsApp from 14,000 km away. The same project that would be a smooth 10 weeks for an owner who could pop in twice a week becomes a 9-month odyssey for someone visiting Greece once a year. The work isn't different; the management gap is. This handbook is how to close that gap in 2026.

It's structured around three things you need to decide upfront — scope, budget tier, and project management model — and then walks through the operational layer that makes the project survive distance.

The three renovation tiers — get clear before you start

Most Greek property renovations sit in one of three tiers. Be honest about which one you're doing.

Tier 1 — Cosmetic refresh (€4,000–€20,000)

• Painting throughout — €1,500–€4,000 for an apartment
• Light-fixture replacement — €300–€1,500
• Floor refinish or carpet replacement — €1,500–€8,000
• Kitchen cosmetic update (worktops, doors, handles, painting, but not full replacement) — €2,500–€7,000
• Bathroom cosmetic (taps, mirror, fittings, no plumbing changes) — €800–€2,500
• Furniture and soft furnishings — €4,000–€15,000

Timeline: 2–6 weeks. Permits required: typically none, provided no structural or plumbing changes. The most diaspora-friendly tier — minimal coordination, predictable outcomes.

Tier 2 — Functional refresh (€20,000–€80,000)

• Full kitchen replacement — €6,000–€25,000 depending on quality tier
• Full bathroom replacement — €5,000–€15,000 each
• Electrical rewiring (partial or full) — €4,000–€15,000
• Plumbing replacement — €3,000–€12,000
• Heating system upgrade (boiler, radiators, or heat pump installation) — €5,000–€18,000
• Air conditioning installation — €1,500–€8,000 depending on units
• New flooring throughout — €4,000–€15,000
• Window replacement (energy-efficient frames) — €4,000–€18,000

Timeline: 8–20 weeks. Permits required: small-works permit (μικρή κλίμακα) for most. The middle tier where diaspora projects most often go wrong because the management complexity exceeds the cosmetic tier without justifying full project-management.

Tier 3 — Major renovation (€80,000–€300,000+)

• Layout changes (removing walls, adding rooms)
• Full envelope renewal (windows, doors, exterior insulation)
• Structural reinforcement
• Roof replacement
• Adding bathrooms or restructuring service areas
• Energy efficiency upgrades qualifying for "Exoikonomo" subsidy programmes
• High-spec finishes and design-led work

Timeline: 4–10 months. Permits required: full building permit for any structural work, plus engineer's design and supervision. The tier where proper project management is non-negotiable.

The permit picture in 2026

Greek property work is regulated under a tiered permit system. As of 2026 the relevant categories:

• No permit required (απλές εργασίες). Cosmetic interior work — painting, flooring, basic fitting replacement. No structural change, no plumbing or electrical alteration to fixed infrastructure.
• Small works permit (έγκριση εργασιών μικρής κλίμακας). Required for changes to plumbing, electrical, partition walls (non-load-bearing), bathroom or kitchen replacement involving plumbing reconfiguration, air conditioning installation. Filed by your engineer with the local town planning office. Cost: €300–€1,000. Approval time: 2–6 weeks.
• Building permit (οικοδομική άδεια). Required for structural change, addition or removal of rooms, change in building footprint, roof reconstruction, addition of a floor, change of use. Filed by an architect or civil engineer with the local town planning office. Cost: €2,000–€8,000 for the permit itself, plus engineering and architecture fees. Approval time: 2–6 months.

Working without the proper permit triggers fines and can derail any future sale or transfer because of compliance issues at the notary. The temptation to "just do the work quietly" — common in older Greek renovation culture — is one of the costliest things a diaspora owner can do, because the unpermitted work surfaces years later at the worst possible moment.

Finding the right contractor for a diaspora project

Three contractor models exist for Greek renovations:

Model A — General contractor (γενικός εργολάβος)

One firm or individual takes responsibility for the entire project, manages the sub-trades, delivers the finished work to your specification. Easier for the owner; price premium of 15–25% over the sum of individual trades.

Best for: Tier 2 and 3 projects, especially for absentee owners. The structural simplicity of one accountable party is worth the price premium.

Model B — Direct-to-trades

You (or your representative) hire individual electricians, plumbers, painters, tilers, kitchen installers separately. Cheaper but management-intensive — someone has to sequence the trades, resolve interface issues, hold each trade to schedule.

Best for: Tier 1 cosmetic refreshes where coordination is light, or where the owner has a trusted on-the-ground project manager.

Model C — Design-and-build firm

A higher-end model where an architect or designer leads the project from concept through delivery, with their own contractor relationships. 25–40% premium over Model A but typically delivers a more polished result with less owner involvement.

Best for: high-end Tier 3 work, Riviera properties intended for premium STR, owners who want a turnkey design-led outcome.

How to vet a Greek contractor as a diaspora owner

The checklist before signing:

• Greek ΑΦΜ and valid VAT registration — verify on the AADE portal (your accountant can check)
• References from at least 3 prior clients you can actually contact
• Photos of completed past work (visit one or two in person via a representative)
• Insurance documentation — public liability, workers' compensation
• Engineer or architect they routinely work with (someone has to sign off on permits)
• Written quotation that itemises labour, materials, VAT, and timing
• Quote that breaks out optional vs included items so you understand the scope precisely
• Realistic timeline — be wary of unusually short promises
• Willingness to sign a written contract (not just a quote)

For diaspora projects above €15,000, we strongly recommend not appointing a contractor without a video tour of at least one previous project, or an in-person visit by someone you trust.

Payment structures that actually protect you

The standard payment structure for a Greek renovation:

• Deposit on signing: 10–20% of contract value. Establishes commitment and lets the contractor procure materials.
• Milestone payments: tied to specific completion points — demolition complete, electrical first-fix complete, plumbing pressure tested, kitchen installed, etc. Each payment 10–20% of total.
• Final payment on completion: typically 10–20%, held until the snag list is closed and the engineer issues completion sign-off.

What to avoid:

• Upfront payment of more than 25% before any physical work has started
• Cash payments above €500 — illegal under Greek tax law and removes your evidentiary trail
• Payment without a corresponding invoice from a VAT-registered contractor
• Payment to a personal bank account that doesn't match the contractor's company name

Always pay by bank transfer to the contractor's business account on receipt of a proper VAT invoice. The 24% VAT on labour and materials is real and unavoidable — the "cheaper without VAT" temptation removes your legal recourse and your insurance position.

Project management at distance — what actually works

The three things that determine whether a remote renovation runs smoothly:

1. A single on-the-ground project manager

Either the general contractor's lead engineer, an independent civil engineer you hire as supervisor (επιβλέπων μηχανικός — costs ~5–10% of project value), or a property/home-watch service with renovation oversight capacity. Whoever it is, they are the one accountable party who visits the site at least twice a week, reports to you weekly, and represents your interests in the dozens of small decisions that come up during the project.

Trying to project-manage from abroad without this layer is the single biggest cause of doubled budgets and tripled timelines.

2. A defined reporting rhythm

Weekly written report from the project manager covering: work completed this week, work planned next week, budget consumed vs budgeted, any decisions awaiting your input, any quality issues, photo documentation of progress. Friday afternoons work well — gives you time over the weekend to respond.

Plus a 30-minute video call every 2 weeks with the project manager on site, walking through the property with their phone camera. Builds your visual mental model in a way photos alone can't.

3. A defined decision protocol

At the start of the project, agree which decisions can be made by the project manager without consulting you, which require email check-in, and which require a video call. Without this, either the project manager pauses for every minor question (you become the bottleneck) or makes decisions you wouldn't have made (you discover them at completion). The middle ground is a written rubric agreed at the start.

The eight mistakes that double timelines and budgets

1. Scope creep without budget control. Decisions made one at a time during the project compound. "While we're at it, let's also do the balcony" three times in a project adds 25% to the bill.
2. Permit work skipped to "save time". Two months later, building inspection or neighbour complaint, work stops, fines, retrospective permitting at premium cost.
3. Trying to project-manage personally from abroad. Decisions delayed by 12-hour time zones turn 10-week projects into 6-month projects.
4. Materials chosen by photo, not sample. Tile colour, flooring tone, paint sheen all look different in Greek light than they do on your laptop in Sydney. Have the project manager show you physical samples on video.
5. No written contract. Quote on email is not a contract. When dispute arises, you have no enforceable position.
6. Paying milestones too early. Pay against demonstrated completion, not against contractor's request to pay before work starts on the next phase.
7. Building manager not informed. The διαχειριστής of the building has rules about construction hours, debris removal, lift use. Cooperate from the start; fight them and they make daily life difficult.
8. Skipping the snag list. The final 5% of the work is what makes the property finished. Don't pay the last 15% of the contract until the snag list is closed in writing.

The Exoikonomo angle for energy upgrades

Greek energy-efficiency subsidy programmes ("Εξοικονομώ", running variants since 2011 and refreshed regularly) can cover 25–80% of the cost of qualifying upgrades — primarily window replacement, insulation, heat pump installation, and solar water heaters. Eligibility depends on owner income and property characteristics; for many diaspora owners (whose income is fully foreign-source), eligibility is favourable.

The programme requires an energy auditor pre- and post-project, qualifying contractors, and AADE-tax-resident applicant status. Worth investigating if your renovation includes any envelope or heating upgrades. The application is bureaucratically complex; your project manager should be able to coordinate it or refer you to a specialist.

How home watch fits the renovation

For our renovation-overseeing members we typically provide:

• Contractor referrals to vetted firms we've worked with
• Site visits 2–3 times per week during active work — independent eyes, not the contractor's
• Weekly photo-documented written reports to you
• Liaison with building manager on access, hours, debris removal, common-area protection
• Materials inspection and approval against your specifications
• Milestone verification before each payment release
• Snag-list creation and closure tracking
• Final completion walk-through with engineer sign-off

See our Renovation Oversight service for the full add-on. Pricing scales with project value — typical engagement runs €1,500–€8,000 for the renovation-overseeing period, depending on tier and duration.
