Municipal vs. state police in Puerto Rico: the differences

They are two separate forces, with two employers

The Puerto Rico Police is a single, state force governed by Act 83-2025. Municipal police are something else: each municipality may establish its own corps, the mayor appoints its members, and the municipality is the employer. Applying to one is not applying to the other.

Before going further, a warning that saves wasted time: almost everything you read out there cites the «Municipal Police Act», Act 19 of 1977. That law is **repealed**. What governs today is the Puerto Rico Municipal Code (Act 107-2020), Book III, Chapter IV. If you are reading requirements that cite Act 19, you are reading expired material.

A municipal corps cannot operate on its own terms. The mayor adopts the organization and administration regulation, the Commissioner of the Puerto Rico Police ratifies it within sixty days, and the Municipal Legislature approves it by a two-thirds vote. Until that happens, the corps does not come into force.

What a municipal officer can do

The Code gives the corps real powers, not symbolic ones, within the municipality's territorial limits. This is what Article 3.025 says, plus what 3.022 adds:

• Make warrantless arrests as law enforcement officers, under Rule 11 of Criminal Procedure.
• Prevent, detect and investigate domestic violence offenses under Act 54, and handle stalking, burglary, assault, misappropriation and misdemeanors under the Penal Code.
• Handle possession of controlled substances under Article 404 of the Controlled Substances Act.
• Enforce Act 22-2000, the Vehicle and Traffic Act, and issue tickets, **except** in fatal accidents or where there is serious bodily harm.
• Compel obedience to the municipality's ordinances and regulations.
• Preventive patrol, protection of municipal property, school zones and traffic direction.
• Pursue crimes beyond the municipality's limits when necessary to complete an intervention that began within their jurisdiction.

Where municipal ends and state begins

The Code draws three clear lines. First: specialized investigation divisions are the exclusive competence of state Police units, the Justice Department, other agencies and the federal government. A municipality may ask the Commissioner to authorize a specialized division, showing the need and the human resources, and the Commissioner has thirty days to accept or deny with reasons.

Second: under no circumstances may the Municipal Police create undercover agent units.

Third, and the one that settles arguments: in cases of jurisdictional or competence conflict, **the state Police always prevails**. Municipal powers do not restrict the state force's.

There is a coordination piece worth knowing if you want to join: the Commissioner is empowered to certify members of the municipal corps who meet the state Police's training requirements, even validating equivalent courses. That certification is what moves you from «Auxiliary Officer» to certified municipal officer.

How you get in: two years on probation

Appointments are made by the mayor. The municipality sets by regulation the rules for entry, re-entry, training and promotions, but not freely: the Code requires an exam, evaluation and investigation system similar to the one the Puerto Rico Police uses, and recruitment rules follow the requirements the state force sets by regulation. In practice, the filter is quite similar to the state one.

One fact worth knowing before applying: if you were rejected by the State Police for failing its requirements, you cannot apply to a municipal corps until the disqualification term established in Act 20-2017 has passed. Applying sooner is wasted effort.

Entry is subject to a **two-year probationary period**, twice as long as many private-sector probationary periods. During those two years the mayor, or the Municipal Commissioner by delegation, may separate you from service at any time if the evaluation shows ineptitude, manifest incapacity, carelessness, partiality or negligence, or if your habits and reliability do not warrant continuing. The Municipal Commissioner evaluates your work every six months.

Two protections you do have: any absence from active service exceeding thirty consecutive days does not count within the probationary period, and if you are separated and believe there were other reasons, you have ten days from written notice to appeal to the Public Service Appeals Commission. Also, all members must pass an intensive preparatory course designed in coordination with the State Police.

The rank ladder and the education each one requires

The Code sets a Uniform Rank System for all municipalities, with academic requirements that rise with the rank. This is the full order:

• Cadet, a member who has not yet met the basic training requirement.
• Auxiliary Officer, a member not yet certified by the Commissioner of the Puerto Rico Police.
• Municipal Officer, the personnel who directly perform the tasks of keeping order and protecting life and property.
• Sergeant; first line of supervision. Minimum: high school diploma or its equivalent by examination.
• Lieutenant, second line of supervision. Minimum: high school diploma or equivalent.
• Captain, third line of supervision. Minimum: an Associate Degree from an accredited institution; alternatively, having served as Lieutenant for more than four years in the State Police, municipal police or a federal agency.
• Inspector, fourth line of supervision. Minimum: Associate Degree. Reached by designation of the Municipal Commissioner with the mayor's confirmation.
• Commander, fifth line of supervision. Minimum: a Bachelor's degree from an accredited institution.
• Deputy Commissioner or Associate Commissioner, by designation of the Municipal Commissioner with the mayor's confirmation.

Your municipality sets the salary

This is the difference that surprises people most. The Puerto Rico Police's new salary scale (Special Order OS-1-3-3, with an officer starting at $43,354 a year) belongs to the state force. **It does not apply to municipal corps.** Each municipality is its own employer and publishes its base salary in its own announcement, so there is no single figure for «municipal police officer in Puerto Rico»: there are as many as there are municipalities with a corps.

To learn what the municipality you want pays, the direct route is its announcement. Look for it in the Central Registry of Announcements at empleos.pr.gov, filtering by that municipality, or call the municipality's human resources office or its municipal police headquarters. We only publish a salary when the official announcement states it.

Promotions do have common rules. They are granted by merit or through exams up to the rank of Captain. When a municipality calls an exam, it must offer it within a period of no less than sixty and no more than ninety days from the announcement. And there is a guarantee worth knowing: once you pass the exam and enter the eligibility register, if the post is available and the fiscal resources exist, the promotion cannot be denied to you.
