A home gym can add value when it provides useful, flexible space rather than simply housing expensive workout equipment. This guide covers how a fitness room affects home gym resale value, buyer appeal, potential ROI, and what to prioritize when creating a gym that works for both you and future buyers.
Realtor’s 2025 trends report put home gyms at #7 on its list of hottest home features, and listings with one showed up 91% more often than the year before. Homes with a dedicated fitness space carried a median list price around $599,000. That’s a big enough shift that it’s worth thinking about before you convert a spare room, not after.
Key Takeaway: A well-built home gym can increase your home’s value when it’s finished, permitted, insulated, and treated as usable living space. The biggest gains come from adding functional square footage and creating a flexible fitness room that appeals to a broad range of buyers. If you’re planning a home addition Van Nuys, prioritize the room itself: flooring, lighting, ventilation, electrical, and flexibility, over expensive workout equipment.

Home Gym Affects Property Value and Buyer Appeal
A home gym can influence value in more than one way, from how the added space is assessed to how useful and appealing it feels to potential buyers.
- Appraised Value
Square footage is square footage to an appraiser, as long as it’s finished and conditioned. A permitted gym addition counts. An extension cord running to a garage rack doesn’t. Van Nuys additions typically add somewhere between $80 and $150 per square foot once the county reassesses the new space, separate from whatever equipment is sitting inside it.
- Marketability
Even buyers who have zero interest in lifting weights usually still like seeing a finished, flexible room. It reads as extra livable space, not a single-use gimmick, and that keeps the listing appealing to more people than just the fitness crowd.
- Flexibility
It matters here too. Pull the flooring and the mirrors and you’ve got an office or a guest room in a weekend. That’s part of why gyms don’t scare off buyers the way, say, a built-in sauna sometimes does. Nobody’s locked into anything.
- Health Culture Shift
This isn’t a pandemic leftover. Civic Science’s 2026 numbers show 52% of U.S. adults now work out at home regularly, against 28% who rely on a public gym membership. Statista has home-equipment ownership sitting around 40% of adults. That’s a real chunk of the buyer pool, and it’s not shrinking.
Did you know? Home gyms are becoming a mainstream home feature, with more than half of U.S. adults now exercising at home regularly.
- Smart use of dead space
An oversized garage bay, an attic with decent height, a bonus room nobody uses, converting one of those into a gym is usually cheaper than a full addition, and it puts square footage to work that was previously just… there.
Expert Note! The room itself usually matters more for resale than the equipment inside it.
- High ROI
It comes up a lot in owner surveys too. Garage Gym Experiment’s 2026 data found 93% of owners say they save time and 43% say they save money versus a public gym membership, which runs about $69 a month on average. Do the math on a year of that and it adds up fast.
- Cost savings
There’s a consistency angle worth mentioning: at-home exercisers are more likely to work out at least once a week than people relying on a gym membership, per the same survey.

- Privacy
It rounds it out. No waiting on equipment. No shared locker room. Not working your schedule around class time. 86% of home gym owners say they prefer training at home over a public gym, and 78% say they work out more often simply because the room is already there.
| Factor | Public Gym | Home Gym |
| Annual cost | ~$828/year membership | One-time build + equipment |
| Weekly consistency | Baseline | 21% higher |
| Property value impact | None | Adds to appraised sq. footage |
| Space flexibility | N/A | Converts to office, guest room, etc. |
Worth noting! More than half of home gym owners say they plan to spend at least $1,000 on the space in 2026.
How to Maximize Your Home Gym’s Resale Value
The room does most of the work here, not the equipment. A few things worth getting right before you start hanging mirrors:
- Keep it convertible. Skip permanent gym-only fixtures, built-in mirrors on every wall, wall racks that leave holes behind. Removable flooring and freestanding gear keep the room’s next use open.
- Upgrade the room itself first. Flooring, lighting, ventilation, outlets. A bare room finished well shows better than a cluttered one with expensive equipment in it.
- Don’t overfill it. One rack, a few dumbbells, a cardio machine reads as useful to almost anyone touring the house. Five different specialty machines start to feel like a hobby room instead of a gym.
- Clear it out before showings. Buyers respond to open space they can picture themselves in.
- Photograph it clean and well-lit. It’s often the room people mention after a showing, for better or worse.
If you’re planning something like this in Van Nuys, an experienced contractor who’s dealt with LADBS permitting and Title 24 compliance before will save you a redo later. Cutting corners on either usually costs more than doing it right the first time.
FAQs

Yes, and it’s not a small bump. Listings with home gyms jumped 91% year-over-year in 2025, and over half of U.S. adults now exercise regularly at home. Most current owners, 60%, expect the trend to keep growing rather than fade.
Is a home gym worth it for regular use?
If you’ll actually use it, generally. Owners report saving both time and money, and the majority say they prefer it to a public gym. The value shows up in habit as much as resale.
Does it raise property taxes in California?
Only on the added square footage. Your existing home stays protected under Prop 13. The new portion gets reassessed at current market rates, typically $80 to $150 per square foot around Van Nuys.
What permits does a Van Nuys gym addition need?
LADBS requires a building permit for any room addition, plus Title 24 energy compliance paperwork, structural plans, and electrical or HVAC permits depending on scope. Fees usually land between $3,000 and $10,000.
What does it cost to build one in Van Nuys?
Somewhere between $125 and $500 per square foot for a typical build, more for premium finishes. A 300 to 400 square foot room usually runs $60,000 to $100,000 total.
Is a Home Gym Worth the Investment
Whether a home gym is worth adding ultimately depends on how often you’ll use it, how much space you have, and whether the finished room adds meaningful functionality to your home. Done right, a home gym adds real value, both in appraised square footage and in how buyers respond to the listing. Done as an afterthought, it’s just equipment in a room.
