Side Income for Firefighters: 5 Ways to Use Your 48-Hours-Off Schedule

A 24-on/48-off schedule is one of the few in this list built for a real side income — the question is which option is worth the fatigue trade-off.

Firefighters have more usable side-income time than almost any other profession here, thanks to a shift schedule that leaves multiple consecutive days off. Many also already hold trade or fitness skills from before the academy. Here are five real options and the honest cost of each — including the fatigue math that most lists skip.

The 24/48 schedule genuinely supports more side income than most jobs, but stacking too many medical or physical shifts back-to-back is a real fatigue risk worth taking seriously, not just a scheduling inconvenience.

Where the real money is

1 Take on contracting or handyman work

Many firefighters already have trade skills; booking work through Thumbtack or word-of-mouth on days off can pay $40-90/hr. The catch: contractor licensing rules vary by state and city, and some departments have policies on outside employment worth checking first. Getting started: check your department's outside-employment policy, then start with word-of-mouth jobs among people you already know before advertising more broadly.

2 Coach personal training or CrossFit

NASM or ACE certification (which many firefighters already hold or can add) opens paid coaching at $30-75/hr for sessions or classes. The catch: building a client base at a gym usually starts with lower pay while you're the newest trainer on staff. Getting started: get NASM or ACE certified if you don't already hold it, then ask a local gym about part-time coaching openings.

3 Pick up per diem EMT/paramedic shifts

Staffing apps like ShiftKey list medical shifts your certification already qualifies you for, often $25-45/hr. The catch: stacking extra 12-24 hour medical shifts on top of a 24/48 fire schedule is a real fatigue and safety consideration, not just a scheduling one. Getting started: download ShiftKey and check what medical shifts are available near you, then pick a light schedule at first to see how the fatigue feels.

4 Offer fire-safety consulting or inspections

Small businesses and landlords pay per inspection for fire-safety reviews. The catch: this niche is narrower and slower to build than general contracting, and often depends on relationships with local property managers. Getting started: reach out to a few local property managers or landlords directly to offer a fire-safety walkthrough at a discounted introductory rate.

5 Run a small vending or laundry-machine route

Machines placed in apartment complexes or gyms can bring in a few hundred dollars a month per few machines. The catch: machines need real upfront capital and ongoing restocking and maintenance trips, so it isn't truly passive. Getting started: research your city's vending-machine placement regulations before investing in equipment.

How much should you realistically expect?

A firefighter using several off-duty days a month for contracting or training work can realistically add $500-1,500/month. Per diem EMT shifts pay well per hour but come with the highest fatigue cost, so many firefighters limit how often they stack them against their fire schedule. As with any of these, treat the first few weeks as a trial run to see how the extra hours actually feel before committing to a regular weekly schedule.

Questions worth answering before you start

Does my department restrict outside employment?
Many departments have specific outside-employment policies, sometimes requiring disclosure or approval, especially for jobs that could create a conflict of interest — check your department's policy manual first.

Is stacking EMT shifts on top of fire shifts actually safe?
It's a real fatigue and safety consideration, not just a scheduling one — several fire-service safety studies have linked chronic sleep deprivation to increased injury risk, so pace yourself rather than maximizing every day off.

Do I need a contractor's license for handyman work?
It depends on your state and the scope of work — many states require a license above a certain dollar threshold per job, so check your state contractor licensing board's rules.

What's the biggest mistake firefighters make with side income?
Taking on too much physically demanding work — contracting plus per diem EMT shifts — in the same week is the most common overreach; build up gradually and watch how you feel after a few weeks.

The bottom line

Given the 24/48 schedule, contracting or personal training on your days off tends to be the most sustainable starting point. Be more cautious about stacking per diem EMT shifts on top of fire shifts — that combination has the highest real fatigue cost of anything on this list.
