What is small-scale works approval?
Small-scale works approval is a simplified permitting process regulated under Article 29 of Greek Law 4495/2017. It allows property owners to carry out specific renovation and modification works without needing a full building permit. This streamlined process is faster and often more cost-effective than obtaining formal building permission, provided the works do not materially change the building structure or fundamentally alter its intended use.
Which works are covered by small-scale approval?
Small-scale works approval covers a broad range of interior and non-structural activities, provided they remain within legal limits set by Greek law. These typically include:
- Interior renovations of residential, commercial, and office spaces
- Modifications to interior layouts using non-load-bearing partitions
- Installation of plumbing and electrical systems within existing spaces
- Installation of air conditioning and heating systems
- Interior joinery work including doors, windows, and built-in storage
- Bathroom and kitchen renovation within defined limits
- Flooring, wall finishes, and decorative treatments
Works that alter the building structure, increase the floor area, change the building's classification, or modify its primary function do not qualify as small-scale and require a full building permit instead.
What documents are required?
To apply for small-scale works approval, you must submit the following documents:
- Application form: The standardized form provided by your municipality or planning authority
- Topographical plan: An up-to-date drawing showing the precise boundaries of your property
- Current-state plan: A drawing showing the existing condition and all planned modifications
- Proof of ownership: Your deed, ΓΕΩΤ.Ε.Ε extract, or equivalent property ownership document
- Identity document: A valid passport or national ID copy
- Technical studies: If works involve electrical, plumbing, or other technical systems, relevant engineering studies may be required
Different municipalities may request additional documents based on the nature of the works or property characteristics. Check with your local authority for a complete checklist.
How do I submit the application?
Applications for small-scale works approval can be submitted in two ways:
- Online via e-Permits: The e-Permits platform operated by the Greek Ministry of Environment and Energy allows electronic submission. This is the preferred method as it saves time and provides a digital record.
- In person: Alternatively, you can visit your local municipality or planning office and submit the documents directly to the counter.
After submission, the planning authority reviews your application for completeness and legal compliance. If all documents are in order, approval is issued. In some cases, the authority may request clarification or additional information before making a decision.
How long is the approval valid?
Small-scale works approval is typically valid for two years from the date of issue. All works must be completed within this time frame. If you are unable to finish within two years, you may apply for an extension or renewal through your local authority, though this is subject to approval and may depend on circumstances at the time of application.
Which works do not require any permit?
Some minor works can be legally performed without any permit or approval. These include:
- Interior painting and surface restoration without dimensional changes
- Installation of wall-mounted cabinets and built-in furniture
- Installation of bathroom fixtures and accessories
- Installation of interior lighting and electrical outlets within existing spaces
- Small agricultural structures on rural land (up to 15 m² in certain zones)
- Installation of household appliances and equipment
Although these works do not require legal approval, you must still comply with all relevant safety codes and technical specifications.
Building permit or small-scale approval: how to choose?
Choosing between a full building permit and small-scale approval depends entirely on the scope and nature of your proposed works:
- Full building permit is required when: Works alter the building structure, increase the floor area, change the building's use category, add new facades, or create entirely new spaces.
- Small-scale approval applies when: Works are confined to interior renovation and modification within legal thresholds, with no structural changes or use-category changes.
Misclassifying your project creates legal problems and may result in forced remediation. Always consult with a qualified engineer or your local planning authority before submitting an application.
Common mistakes to avoid
When applying for small-scale works approval, property owners frequently make errors that lead to rejections or delays:
- Incomplete documentation: Missing drawings or signatures force the authority to request supplements, extending the process.
- Outdated topographical plans: Using old drawings that don't match the current property condition.
- Exceeding small-scale limits: Proposing works that fall outside permitted scope, requiring a full building permit.
- Starting work before approval: Beginning construction before receiving formal approval is illegal.
- Lack of professional supervision: Proceeding without an engineer to oversee compliance and quality.
To avoid these pitfalls, engage a qualified engineer from the outset to guide you through the process and ensure all requirements are met.
Frequently asked questions
What works are classified as small-scale?
Small-scale works fall under simplified approval when they involve renovations, modifications to interior spaces, installation of plumbing and electrical systems, fitted joinery, and similar improvements within legal thresholds. The key constraint is that they must not materially alter the building structure or change its primary function. The specific classification depends on the property type and local regulations.
What documents do I need to submit?
Required documentation typically includes: the application form (obtained from the municipality), a topographical plan of the property, a plan showing the current state and proposed changes, proof of ownership (deed, ΓΕΩΤ.Ε.Ε extract, etc.), identity document, and in some cases technical studies if the works involve electrical or plumbing systems. Each municipality may request additional documents depending on the work type.
How much does a small-scale works permit cost?
The cost of small-scale works approval is typically significantly lower than a full building permit, but varies by municipality and work type. Each municipality sets its own fees independently. Contact your local planning authority or a technical engineer for specific pricing information relevant to your project.
How long is the small-scale works permit valid?
A small-scale works permit is typically valid for two years from the date of issue. The works must be completed within this period. If completion is not possible within the timeframe, it may be possible to renew or extend the permit through a formal procedure with your municipality.
Do I need an engineer to supervise small-scale works?
While not always mandatory, depending on the complexity of the works and your municipality requirements, having an engineer supervise is recommended and often required. An engineer ensures compliance with standards and regulations, and their involvement protects you legally and technically.
Does a small agricultural storage building under 15 square meters need a permit?
Small agricultural structures, such as storage buildings under 15 m², are often exempt from permitting requirements under certain provisions. However, this depends on local regulations and the specific zone classification. Always verify with your local planning authority before starting any work.
What happens if I carry out works without approval?
Performing construction works without proper approval or permit is illegal and carries serious consequences. These include administrative penalties, substantial fines, and in severe cases, court-ordered demolition or restoration of the original condition. It also creates major complications when selling the property and causes difficulty obtaining financing.
What is the legal basis for small-scale works permits in Greece?
Small-scale works approval is governed by Article 29 of Law 4495/2017, which establishes the criteria, conditions, and procedures for approval. This legal framework allows certain minor construction and renovation works to proceed with simplified approval rather than full building permits.
