In short
Rule 4.3.13 of Joint Regulation No. 9473 sets how the premises of a beauty salon, a barbershop, a tattoo studio or an analogous establishment must be and must operate. It starts with space: they must have a minimum of one hundred square feet of floor, excluding the toilets, and that minimum is for an establishment where a single professional works; if more than one barber or specialist is offering services at the same time, there must be forty additional square feet per professional. They must have separate toilets for women and men, available to clients and employees, supplied with liquid soap, paper towel, toilet paper and a bin. Operations of this nature are not permitted in a residence, unless the area or premises to be used commercially is totally separate or independent from the residence. The most detailed part is hygiene: every tool coming into direct contact with the person is disinfected after each use by immersion, with germicides classified by the EPA as hospital-grade disinfectants, and the ultraviolet cabinet does not substitute for germicidal agents. Every razor must be disposable or single-use. Reusing towels without sanitising them and using common sponges or puffs are prohibited. And every person practising these professions must be vaccinated against hepatitis B.
What is it?
It is Rule 4.3.13 of Chapter 4.3 of Joint Regulation No. 9473, on the Health Licence, dedicated to the requirements for the design and operation of beauty salons, barbershops, tattoo studios and analogous establishments. It is thirty-one requirements about the premises, their toilets, the water, ventilation, separation from other structures, waste, the hygiene of tools and towels, the professional’s health and hygiene, and the prohibitions. This site already has guides on the professional licence for a barber or stylist and on the tattoo studio licence, and a general guide on the Health Licence written from other rules of the same chapter; this one covers the premises standard, which none of them carries.
Who can do it?
The requirements apply to beauty salons, barbershops, tattoo studios and analogous establishments. The rule expressly adds that its provisions also apply to mobile beauty specialists, mobile barbers, aestheticians and other analogous professions. And it excludes from one specific requirement — that of not having direct communication with another establishment that is not an integral part of the business — the barbershops and beauty salons located in hotels, student centres, shopping centres and other analogous establishments. To practise the profession, every person must hold a licence from the corresponding Examining Board or the colegiación, if required by law.

Step by step
Step 1: The size: a hundred feet, and forty more per professional
The establishments must have a minimum of one hundred square feet of floor, excluding the toilets. The regulation clarifies which case that minimum is for: this minimum size is permitted for an establishment where a single professional works. If more than one barber or specialist is offering services at the same time, there must be forty additional square feet per professional. It is the first calculation to make before signing a lease: a hundred for the first and forty for each additional chair that will be working at the same time.
Step 2: The toilets
They must have separate toilets for women and men, conveniently located, available to clients and employees. The number of sanitary installations follows the current Puerto Rico Construction Code, though the regulation itself says this may be waived by a variance or exception application under Rule 4.3.3 of the chapter. The toilets are kept clean at all times and in good repair, supplied with liquid soap, paper towel or another hand-drying fitting, toilet paper and a bin. And they must be well lit and adequately ventilated.
Step 3: From home: only if it is totally separate
Operations of this nature are not permitted in a residence, unless the area or premises to be used commercially is totally separate or independent from the residence. And even then, the separate toilets for women and men must be provided, conveniently located, available to clients and employees. That is: the house’s kitchen or living room do not qualify; an area with its own entrance and toilets, independent of the dwelling, is needed.
Step 4: Hot water and washbasins
They must be provided with enough hair-washing basins; the number of basins in the establishment is determined by the number of clients and the establishment’s particular need. And there must be a supply of potable water, cold and hot, with sufficient pressure, from a water supply approved by the Department of Health. The three elements — potable, hot and pressurised — go together in the text and are checked together.
Step 5: Ventilation, separation and what may not be done with the premises
The premises must have adequate natural or artificial ventilation allowing the extraction of objectionable gases, vapours or odours to the outside of the building, and they may not ventilate into the interior of other parts of the structure. They may not have direct communication with any other establishment that is not an integral part of the business — barbershops and beauty salons located in hotels, student centres, shopping centres and other analogous establishments are excluded from this provision. Using beauty salons or analogous establishments as a bedroom is prohibited. And the separation between these establishments and any other structure is by walls built from floor to ceiling, with no holes or openings.
Step 6: Waste and pests
All solid waste is deposited in receptacles of non-absorbent material with well-fitting lids, and taken out of the establishment in sealed plastic bags as often as needed so it does not become a public health danger or a public nuisance. Every owner or lessee is responsible for keeping the establishment and its surroundings free of animals, insects, rats and other vermin; all areas must be kept clean and free of solid waste, and the physical plant must be kept in good repair.
Step 7: The tools: immersion, not ultraviolet
This is the rule’s heart. Hairbrushes, combs, tools, tongs or tweezers, files, cuticle pushers, blackhead removers, scissors, contact cups or massage-machine pads, and any other kind of tool, instrument or object used in these establishments that comes into direct contact with the person, are disinfected after each use and kept properly in a cabinet. And the regulation closes the easy escape: storage in an ultraviolet cabinet does not substitute for the use of germicidal agents. The use of unsanitised instruments is prohibited. For disinfection, chemical germicides classified by the US Environmental Protection Agency as hospital disinfectants are used, at the concentration and contact time the manufacturer recommends. And the washing and sanitising system is by immersion of the object in the solution for the stipulated time; every establishment must have the equipment to carry out that process.
Step 8: The disposable razor and the spare set
Every razor used must be disposable or single-use. The razor holder must be sanitised after each use. And the establishment must keep an accessible spare set of razors. That last line exists for a practical reason: without an accessible spare, the temptation to reuse is exactly what the regulation wants to eliminate.
Step 9: Hands, towels and single-use material
Every professional must wash their hands properly with soap and water or a bactericidal solution before attending each client. If a client affected by a rash, cut, inflammation or purulent lesion is attended, the whole contact area is disinfected immediately, after washing with soap and water, followed by an effective disinfectant. Aprons, towels, head protectors and any other analogous non-disposable material are subjected to washing and disinfection after each use; where plastic protectors are used, paper towel must be used so they do not touch the client’s skin directly. All common-use towels are kept in closed compartments and each towel is strictly sanitised after being used; reusing towels without proper sanitising is prohibited, and the use of common sponges or puffs is prohibited. And single-use material is deposited after use in a sanitary receptacle and may under no circumstances be used on more than one client.
Step 10: The person: hygiene, hepatitis B and licence
Both employees and owners practising a profession related to the establishment’s operations must keep their clothes clean and in good condition, their nails trimmed and clean, and take care that their person is in perfect health. Every person, owner or employee, working as a beauty technician or specialist, barber or in analogous professions, practising in Puerto Rico, must be vaccinated against hepatitis B. And to practise the profession, every person must hold a licence from the corresponding Examining Board or the colegiación, if required by law.
Step 11: What may not be offered, and smoking
Every medicinal product used to coagulate blood is used only as a solution or powder and applied with sterilised gauze or cotton. Beauty specialists, barbers and analogous professionals do not give treatment for skin diseases; they may only give the facial and scalp treatments recommended by the field’s textbooks, provided no legislation or approved regulation is violated. And smoking is prohibited inside every beauty salon, barbershop or analogous establishment.
Step 12: If you work at clients’ homes
The rule closes by extending its reach: this article’s provisions also apply to mobile beauty specialists, mobile barbers, aestheticians and other analogous professions. That is: the rules on immersion disinfection, disposable razors, sanitised towels, single-use material and hand-washing before each client do not stay in the premises: they travel with the professional.
Where to do it
These requirements are checked within the Health Licence process before OGPe and in the Department of Health’s inspections. If you need to be exempted from the number of sanitary installations the Construction Code sets, the chapter itself allows requesting it by a variance or exception under its Rule 4.3.3. The licence to practise the profession is issued by the corresponding Examining Board, which is a separate process and has its own guide on this site.
How long it takes
What to do if something goes wrong
The costliest mistake is made before opening: renting premises without doing the square-footage calculation. It is one hundred square feet of floor, excluding the toilets, for a single professional, plus forty additional per professional who will be offering services at the same time. The second is trying to operate from home without an area totally separate and independent from the residence, with its own separate toilets for women and men. The third is a daily-operation one and the one that appears most at inspection: the ultraviolet cabinet does not substitute for germicidal agents, and the sanitising system must be by immersion, with germicides classified by the EPA as hospital-grade disinfectants, and with the equipment to do it available on the premises. And if you are a client, there are three things you can look at knowing nothing about regulations: that the razor is disposable, that the towel comes out of a closed compartment and that the professional washes their hands before attending you.
Common mistakes
- Renting premises under one hundred square feet of floor, not counting the toilets.
- Putting several chairs working at once without the forty additional square feet per professional.
- Operating inside the residence without an area totally separate and independent from it.
- Not providing separate toilets for women and men available to clients and employees.
- Relying on the ultraviolet cabinet as a disinfection method.
- Disinfecting without immersion, or without germicides classified by the EPA as hospital-grade.
- Reusing razors instead of using disposable or single-use ones, or not keeping the spare set accessible.
- Reusing towels without sanitising them, or keeping them outside closed compartments.
- Using common sponges or puffs.
- Reusing on another client material that is single-use.
- Ventilating the premises into the interior of other parts of the structure.
- Using the salon as a bedroom, or allowing smoking inside the premises.
- Practising without the hepatitis B vaccine or without the corresponding Examining Board’s licence.
Frequently asked questions
How many square feet does a beauty salon need?
A minimum of one hundred square feet of floor, excluding the toilets. That minimum size is permitted for an establishment where a single professional works; if more than one barber or specialist is offering services at the same time, there must be forty additional square feet per professional.
Can I set up a barbershop or salon in my home?
Operations of this nature are not permitted in a residence, unless the area or premises to be used commercially is totally separate or independent from the residence. In that case, the separate toilets for women and men must also be provided, conveniently located and available to clients and employees.
Does the ultraviolet light cabinet work for disinfecting?
Not as a disinfection method. The regulation says expressly that storage in an ultraviolet cabinet does not substitute for the use of germicidal agents. Disinfection is done with chemical germicides classified by the EPA as hospital disinfectants, at the concentration and contact time the manufacturer recommends, and by immersion of the object in the solution; the establishment must have the proper equipment for that process.
Can the barber reuse the razor?
No. Every razor used must be disposable or single-use. The razor holder must be sanitised after each use, and the establishment must keep an accessible spare set of razors.
Do you need a vaccine to work in this?
Yes. Every person, owner or employee, working as a beauty technician or specialist, barber or in analogous professions, practising in Puerto Rico, must be vaccinated against hepatitis B. Moreover, to practise the profession you must hold a licence from the corresponding Examining Board or the colegiación, if required by law.
Do these rules apply if I work at clients’ homes?
Yes. The rule says expressly that its provisions also apply to mobile beauty specialists, mobile barbers, aestheticians and other analogous professions.
