- allergic to dogs trait
- chronic headaches trait

Sims 4 Spa Day Traits by Kuttoe
NOTE: This trait was last updated on 8/21/25 for patch 1.117.227
This sims 4 traits bundle includes the health nut trait and the high maintenance trait.
This cc traits mod gives you more of a reason to utilize the content that came with the Spa Day pack and to visit spas more often.
Your health nut sims will get powerful moodlets from yoga and drinking teas. And high maintenance sims will have a hard time in physical labor careers (military, manual labor, & fast food), but be great at the critic career. So funny!
The traits come with new buffs, social interactions, and custom whims.
UPDATE: These have been updated for the newest version of Spa Day. The high maintenance trait is now the lavish trait.
Sims 4 Pastry Lover Trait by Caradriel
The pastry lover sim will be much better at baking and gourmet cooking than other sims. They’ll also receive 10 custom buffs and 3 new social interactions.
One of my favorite features of this cc trait is that your sim can ask another sim about their favorite cake. You’ll even get an answer from them. Imagine making a sim their favorite kind of cake for their birthday!!
This trait would match well with the custom chocolatier career which can be found here. Overall, this is a great trait mod for storytelling and more in-depth gameplay.
Sims 4 Shy Trait by MarlynSims
Having the shy trait will really affect your sim’s life. Their social, charisma, and comedy gain at only 0.2x instead of the typical 1x. They gain relationships with pets much faster than they do with humans (relatable).
Your sim will also get positive buffs when doing communication tasks through the phone or the computer instead of in-person (super relatable.)
Sims 4 Zodiac Sign Traits by Radiophobe
This is a huge astrology mod for the sims 4. The creator attempted to recreate the zodiac signs from the sims 2 and nailed it!
This trait mod comes with TONS of new whims and your sims will autonomously do things that correlate with their zodiac signs. For example, a Virgo sim might start cleaning up around the house since Virgo’s tend to be neat and organized.
You can find the zodiac signs in the rewards store so they won’t take up one of our precious trait slots.
Sims 4 Eating Disorders Trait Mods by DaleRune
This sims 4 eating disorder trait mods includes:
- binge eating disorder trait
- avoidant / restrictive food intake disorder trait
- anorexia trait
- bulimia trait
- picky eater trait
I’m not going to go into any detail about this traits mod, in case it’s triggering to any of my readers, but you can go to the download page to get all of the details.
*I want to acknowledge that some of these cc traits talk about very sensitive topics. The point of these types of mods is to add more realism to The Sims 4. However, I would totally understand if it comes across as offensive or insensitive to anyone currently struggling with these illnesses. I am truly sorry if that is the case and I wish you healing and happiness.*
Sims 4 Hates Outdoors Trait by MarlynSims
We were given a loves outdoors trait, but not a hates outdoors trait. Makes sense. But lucky for us, MarlynSims has created a very in-depth hates outdoors trait for our sims.
With this trait, your sims will struggle to excel at any careers that require them to be outdoors (gardener, lifeguard, conservationist, etc.) and they will never autonomously start any outdoor activity.
In addition, any skill that involves the outdoors will gain 0.4x slower. This sim really hates the outdoors.
Sims 4 Hobby Trait Mods by Kuttoe
This sims 4 trait mods include:
- artisian trait
- horticulturist trait
- movie buff trait
- scribe trait
- tinker trait
- worldy trait
- competitive trait
- technophobe trait
This group of cc traits is based on a sim’s hobbies. If your sim doesn’t practice their hobby often (like watching movies or gardening) they will become stressed.
Or in the case of the technophobe trait, they will get stressed by using technology. Each of the traits comes with new buffs and social interactions.
Sims 4 Toddler Traits Bundle by Snowiii95
This sims 4 cc traits for toddlers pack includes:
- always happy trait
- naive trait
- bossy trait
- creative trait
- stranger danger trait
- bookworm trait
- fast learner trait
I was getting so BORED with the traits we have for toddlers, so I’m super happy that I was able to find a sims 4 cc trait mods for toddlers.
I especially love the fast learner trait. It makes teaching your toddlers skills much easier and faster.
Shutterbug Trait by MarlynSims
Sims with the shutterbug trait love photography. They even build their photography skills 1.6x faster than normal.
And the best part about the trait is that your sims will earn 4x as much money for their photographs as other non-shutterbug sims would!!
This trait would go perfectly with the semi-active photography career you can find here.
Sims 4 Seducer Trait by KiaraSims4Mods
Seducer sims know how to get their way when it comes to romance. They have special new interactions like “Do you know amazing you are?” and “I’ll never get over you” to win over new lovers.
These sims frequently get whims to do romantic things and enjoy new buffs when woohooing or trying for a baby. This trait makes for a spicy love life!
Sims 4 Beach Lover Trait by KiaraSims4Mods
The beach lover trait is perfect for your sims that live in Sulani. With this cc trait, your sims will get special buffs from doing beach-related activities like sunbathing, diving in the ocean, sailing on a boat, and more.
Your beach lover sims will also get two new interactions: talk about the beach & chat about beach views.
Sims 4 Trait Mods Seasons Trait Pack by Vicky Sims
This sims 4 trait mods includes
- child of winter trait
- child of the moon trait
- child of spring trait
- child of summer trait
- child of the sun trait
- child of fall trait
I LOVE this trait pack. Seasons definitely affect us as humans and I’m sure they affect our sims too. When it’s fall, I feel so happy. I love the warm and cozy feelings of the autumn season. Now fall can have the same effect on my sim. So cool!
These traits come in the reward store (in addition to CAS) so they don’t have to take up one of your sim’s trait slots.
Sims 4 Social Anxiety Trait by Scarlet & Kuttoe
NOTE: This mod was Last updated July 22nd, 2025
This is another sims 4 mental illness trait. This one specifically deals with social anxiety. I find this trait to be pretty similar to the agoraphobia and shy traits we’ve previously talked about. But it does have a few features that make it unique.
For example, with the social anxiety trait, your sim can take medication for their social anxiety, but they will receive one random side effect. These side effects include decreased appetite, dizziness, nausea, or drowsiness.
Sims 4 Brave Trait by KiaraSims4Mods
This sims 4 cc trait is perfect if your sim is looking to excel at the military, detective, astronaut, or firefighter careers. They’ll earn a 2x career boost just by having the brave trait.
Your sim will also learn fitness 2x faster and get two new social interactions: brag about being brave & you’re safe with me.
Please note that this mod conflicts with Clumsy, Lazy, Loner, Squeamish, and Socially Awkward traits.
Sims 4 Night Owl Trait by KiaraSims4Mods
I absolutely love this custom trait! With this trait, your sims will thrive when the moon is out.
They also love the entire nightlife scene. Your sim will get whims to want to travel to clubs and be uncomfortable during daylight hours.
Sims 4 Vegan Trait by KiaraSims4Mods
I know that a vegan trait for the sims 4 has been requested a lot! Well, finally it’s been made.
With this trait, your sim will not eat meat or any animal products at all ( think eggs, honey, etc.) and they don’t even want to use products that contain animal products.
Sims 4 Industrialist Trait by MarlynSims
This sims 4 cc trait is basically the opposite of the green fiend trait that comes with the Eco Living expansion pack. Instead of loving an eco-friendly environment, your sim actually enjoys the smog and pollution that comes with living in an industrial area.
They have no desire to work in a “green” career field and gardening just isn’t their thing. They even have a hard time making friends with tree huggers who are green fiends, recycle disciples, and freegans.
Sims 4 Vacationer Trait by KiaraSims4Mods
Does your sim love to take vacations? This is basically a sims 4 loves to travel trait.
This trait gives your sim more reasons to take a vacation to the wonderful worlds of Granite Falls or Selvadorada. This trait mod comes with a bunch of new interactions, buffs, and your sim will gain fun 2x faster while on vacation.
Sims 4 Updated CC Traits Mod by Snowiii95
This sims 4 traits pack includes:
- brave trait
- hydrophobia trait
- loyal trait
- animal lover trait
- panic disorder trait
- loser trait
- hopeless romantic trait
- virtuoso trait
It’s a bundle of random, but useful traits. It’s part one, so I assume a part 2 will be coming soon with even more updated traits.
A lot of these cc traits seem to be remade from sims 3. The sims 3 had SO many great traits, so I’m glad to see it!
Sims 4 PTSD Trait by MarlynSims
This is another mental illness trait for sims 4. This time the trait deals with PTSD, otherwise known as Post Traumatic Stress Disorder.
This cc trait is SUPER interesting because your sim has a chance of randomly getting this trait after going through a traumatic life event. Like a divorce, being fired, or the death of a loved one.
When your sim has this trait, they can go to therapy sessions and even possibly recover therefore losing the PTSD trait. This is a very in-depth trait mod, so I highly recommend reading through the download page to learn all about it!
Sims 4 Faithful Trait by KiaraSims4Mods
What sim wouldn’t want to marry a faithful sim? When your sim has the faithful trait, they will get two new social interactions: “express faithful love” & “you’re my forever”
They’ll also get special buffs and whims related to being an extremely loyal sim.
Sims 4 Gold Digger Trait + Aspiration by MarlynSims
This sims 4 cc trait is special because it actually comes with an aspiration too! The trait and aspiration are pretty self-explanatory. Your sim is a gold digger who seeks out wealthy sims then mooches money from them.
It adds 14 new interactions, 16 new buffs, and the aspiration has 4 levels to it. The new gold digger aspiration can be found in the love category.
Sims 4 Fairy Trait Mod by Just Kizzy
From reading around the sims forums and various comment sections of youtube videos, I’ve discovered that lots of simmers really want fairy sims.
Unfortunately, it doesn’t look like we’ll be getting them any time soon. BUT I have found this fairy mod that may just satisfy your fairy wishes for the time being.
This sims 4 fairy trait comes with the trait, buffs, whims, and custom interactions. If you’d like a more in-depth look at fairy mods, let me know and I will definitely test and find the very best ones for a future post.
Sims 4 100 Base Game Traits Pack by Vicky Sims
NOTE: This mod is compatible with patch 1.117 Aug 19
I’ve saved this HUGE cc trait pack for last. It’s a 5-part mod that totals 100 cc traits for sims 4. That’s absolutely crazy.
What’s even crazier is that each of these traits comes with custom buffs, whims, CAS animations, relationship impacts, and emotional impacts.
According to Vicky Sims:
- part 1 is focused on stimulation & emotional response traits
- part 2 is focused on extroversion, social image, and social behavior traits
- part 3 is focused on intimate relationships
- part 4 is focused on subjective qualities of sims’ appearance
- part 5 is focused on talents and weaknesses that a sim is born with. (which reminds me a lot of one of my favorite mods that you can find on this list.)
5 Sims 4 Trait Mods by jessienebulous
I was SUPER impressed by these custom traits. The icons are spot on and the descriptions are great. With this trait pack, you’ll receive the space cadet trait, gearheart trait, charming trait, insightful trait, and dramatic trait for sims 4.
One of my favorite traits included is the gearheart trait. I just think it’s very unique compared to other traits we have. This trait helps sims build handiness and rocket science skills faster. Plus they get 3 unique social interactions!
8 Custom Traits for Sims 4 by jessienebulous
This is another new custom traits pack by jessienebulous. Once again, I was so impressed by the icons and the trait mods themselves. They add a lot of depth which I love.
This trait mod pack includes the witty trait, cool trait, film buff trait, morning person trait, night owl trait, lusty trait (spicy!), shy trait, and the baby crazy trait. Eight brand new traits for your sims 4 game!
(BTW This picture doesn’t include all of them. I forgot to add the shy trait 🤦)
Rainbow Baby Trait by DaleRune
This rainbow baby trait will add that next level of realism to your sims 4 gameplay. Rainbow babies are very cherished by their families. They are babies that are wanted beyond belief.
It’s a trait that’s perfect for storytelling and is even better when used with sims 4 pregnancy mods.
Sims 4 Myers Briggs Personality Traits Pack by InsightBond
If you’re not familiar with the Myers-Briggs Personality test, it’s basically a long series of questions that divides people into 16 distinct personality types to discover your strengths.
With this cc traits pack, you can give your sims their very own Myers-Briggs personality type or create a sim based on your own personality type!
Sims 4 Claustrophobic Trait by Splendiferous Sims
This trait mod is the perfect addition to Sims 4 Tiny Living gameplay!
Imagine being a sim that gets terrible claustrophobia but is forced to live in a tiny home.
Now that could make for some VERY interesting storylines!

Sims 4 Trait Mods FAQ (2026)
1. Are Sims 4 trait mods safe to use?
Yes, trait mods are generally safe when downloaded from reputable creators and updated regularly. Problems usually occur when trait mods are outdated or conflict with other gameplay mods that modify moods, autonomy, or personality systems.
2. Do trait mods work with the latest Sims 4 patches in 2026?
Because they’re not script mods, most actively maintained trait mods work with current 2026 patches. However, EA frequently updates personality-related systems, so older trait mods may need updates after major game patches to function correctly.
3. Can I use multiple trait mods at the same time?
Yes, you can use multiple trait mods together. Issues only arise if two traits try to override the same behavior, moodlets, or autonomy rules. Be sure to read the compatibility notes to help avoid conflicts.
4. Will custom traits show up in Create-a-Sim (CAS)?
Yes, they will. You must assign the traits in CAS under custom trait categories, so they show up in your gameplay. However, some mods add traits through gameplay rewards or menus instead, depending on how the creator designed them.
5. Do trait mods affect autonomous behavior?
Many trait mods do. Some change how Sims react emotionally, make decisions autonomously, or interact with other Sims. Others are mostly descriptive and affect moodlets without altering behavior heavily.
6. Can trait mods impact game performance?
Trait mods are usually lightweight and rarely affect performance. However, if you use many script-based personality mods at once, they can increase simulation load, especially in large households or long-running saves.
7. Are trait mods compatible with expansion packs?
Compatibility depends on the trait. Some traits require specific expansion packs to function properly, while others are base-game compatible. Always check the pack requirements before installing.
8. Can I remove a trait mod mid-save?
You can, but it’s not recommended without caution. Removing a trait mod while Sims are actively using those traits can cause missing moodlets or reset behaviors. It’s safest to remove traits from Sims first, then uninstall the mod.
9. Do trait mods work with story progression or autonomy mods?
Some do, some don’t. If both mods modify autonomy, emotions, or personality logic, conflicts may occur. Creators often list compatible or incompatible mods in their descriptions, so check these out before downloading.
10. Can I use trait mods on toddlers, children, or teens?
Many trait mods are age-specific. Some are designed only for adults, while others support teens or younger life stages. Always confirm age compatibility to avoid traits not appearing or functioning incorrectly.
11. Why aren’t my custom traits showing up in CAS?
This usually happens because:
- The mod is outdated
- Required expansion packs are missing
- The trait uses gameplay unlocks instead of CAS
- The mod is placed too deeply in the Mods folder
Update the mod and clear cache files to fix the issue.
12. Are trait mods available for console players?
No. Trait mods are only available on PC and Mac. Console versions of The Sims 4 do not support mods or custom scripts.
