Managing a short-term rental in Portugal involves more than having a comfortable, well-decorated space. Mandatory signage is a legal requirement that many property owners discover too late – sometimes only during an inspection.
In this complete guide, we explain everything about mandatory signage for short-term rentals: from the identification plate that must be at your door to the safety signs that protect your guests. Get ready to meet 100% of legal requirements and avoid fines.
What is Short-Term Rental Signage?
Short-term rental signage is the set of plates, signs, and notices that must be visible at your property to:
- Identify the accommodation to authorities and guests
- Ensure safety of users
- Inform about rules and emergency equipment
- Comply with current legislation
Signage is divided into three main categories:
- Identification plate (exterior/entrance)
- Safety signage (photoluminescent)
- Information notices (non-smoking, noise, etc.)
Mandatory Signage: What Does the Law Say?
Legislation regarding short-term rental signage is spread across several legal documents:
- Decree-Law No. 128/2014 (amended by Law 62/2018): Security and identification requirements
- Ordinance No. 262/2020: Identification plate specifications
- Law No. 56/2023: Noise hours signage (condominiums)
- Decree-Law No. 220/2008: Fire safety (for properties with 10+ guests)
Important note: Requirements vary according to modality (house, apartment, room, hostel) and capacity (up to 10 or more than 10 guests).

How to Install Signage Correctly?
Installation Height
Upper level signage (extinguisher, blanket, exits):
- Height: Between 2m and 2.2m from floor
- Must be visible even with people in front
Lower level signage (information, warnings):
- Height: Between 1.4m and 1.7m (eye level)
Fixing Methods
For photoluminescent signage:
- Double-sided tape (quick solution, less durable)
- Mounting adhesive (more resistant)
- Avoid nails or screws that damage signage
For identification plates:
- Stainless steel screws (mandatory for 20x20cm plate)
- Follow ordinance specifications regarding wall clearance
Maintenance
✅ Check periodically:
- Signage is visible (not obstructed by furniture/objects)
- Photoluminescent plates are clean and legible
- Fixings are secure
- Information is updated
Signage Kits: Worth It?
Many suppliers offer complete short-term rental signage kits. Advantages:

Frequently Asked Questions
Can I make my own identification plate?
Technically yes, but you must strictly follow Ordinance 262/2020 specifications. Any deviation (color, font, material, dimensions) can result in non-compliance.
Does photoluminescent signage need light to work?
Yes. Photoluminescent plates "charge" with natural or artificial light and then emit light in the dark. They must be in locations that receive lighting during the day.
How long does signage last?
Quality signage lasts 5-10 years if well maintained. Photoluminescent plates lose effectiveness over time and should be replaced when no longer clearly visible in the dark.
Do I need a safety project?
For properties up to 10 guests: no.
For properties with more than 10 guests: yes, SCIE project is mandatory.
Where to buy certified signage?
ANEPC-registered companies, specialized safety suppliers, or online stores dedicated to short-term rental equipment. Always verify certifications.
Does signage need to be in multiple languages?
Only the information book has this requirement (4 languages). For safety signage, universal pictograms are generally sufficient. For information notices (noise, etc.), at least Portuguese and English is recommended.
Conclusion
Short-term rental signage is a small investment that protects your business from big problems. For less than €100, you ensure full legal compliance, guest safety, and peace of mind during inspections.
To recap the essentials:
- ✅ Identification plate at entrance (except houses on mainland)
- ✅ Photoluminescent safety signage (extinguisher, blanket, first aid)
- ✅ 112 sign clearly visible
- ✅ Noise hours (if in condominium)
- ✅ Information signs (no smoking, complaints book)
Don't leave signage to the last moment. An inspection can happen at any time, and non-compliance consequences go far beyond fines – they can compromise your entire property operation.
