The Sims 4: Lot Challenges, Explained

The Sims 4 highlights many facets of life—the highs and lows—and is an ideal game for storytellers and designers alike. Life simulation games typically include laid-back gameplay like community building, character creation, and social relationships.

However, certain life simulations have chaotic moments, especially the Sims franchise. Lot challenges are one way The Sims 4 continues to build upon its gameplay systems by shaking things up with spontaneity that makes the in-game worlds come to life.

Updated May 22, 2025, by Taylor Pittman: Simmers are always finding new ways to make the popular life sim, The Sims 4, more challenging. Community challenges, scenarios, and lot challenges add restraints, difficulties, or guidelines that players must follow. Expansion packs add new content to the free base game, such as careers, traits, gameplay, and lot challenges. We've updated this guide to include information on the added lot challenges in the base game, Horse Ranch, and For Rent in The Sims 4.

What Are Lot Challenges in The Sims 4?

Lot Challenges were first seen with patch115 in July 2021 and revamped the lot trait system by splitting "good" and "bad" lot effects. Lot challenges started as lot traits but became a separate feature after the patch, although they are found in the same panel. Many are included in DLC and can have broader effects on the lot they are attached to. As the name insinuates, lot challenges trigger harder gameplay or have negative consequences on the lot, like natural disasters.

There are 18 Lot Challenges in The Sims 4, with only three being a part of the base game.

Base Game Lot Challenges

3 Lot Challenges

The Sims 4 base game is free to play, so anyone can enjoy the franchise without breaking out their wallet if they aren't worried about getting any DLC. The base game's lot challenges include Off-the-Grid, Scare Seeker, and Heist Havoc.

Off-the-Grid

Icon	Description
	Off-the-Grid lots don't have access to water or power lines attached to the city utilities. As a result, Sims will need to use Off-the-Grid items that don't require typical electricity or plumbing, and they get to avoid utility bills.

Scare Seeker

Icon	Description
	Lots with the Scare Seeker trait have an ominous aura, and Sims often find themselves with the scared moodlet. Additionally, occult Sims are more likely to walk around the lot's neighborhood.

Heist Havoc

Icon	Description
	Heist Havoc adds flair to the burglars in The Sims 4. Lots with this trait are more likely to be visited by burglars, and alarm systems can develop issues.

City Living Lot Challenges

6 Lot Challenges

City Living introduces apartments, community festivals, and new careers to The Sims 4. Many of the lot challenges are inspired by the not-so-fun parts of cheap apartment living. City Living lot challenges include Cursed, Filthy, Gremlins, Grody, Quake Zone, and Spooky.

Cursed

Icon	Description
	Cursed lots are full of bad luck and weird vibes. Things are more likely to break, catch fire, and Sims have a higher risk of dying from physical deaths like electrocution and exhaustion. Sims can also get put under voodoo when entering the lot.

Filthy

Icon	Description
	Filthy lots get dirty faster. Countertops, sinks, toilets, showers, and bathtubs will become dirty twice as quickly.

Gremlins

Icon	Description
	Gremlin lots say they have tiny creatures that cause mischief around the place at night, but players don't see any Gremlins appear. Instead, at midnight every night after everyone goes to bed, objects like sinks, showers, and toilets will break.

Grody

Icon	Description
	Grody lots are similar to filthy lots, but rather than physically seeing the dirt, Sims get overwhelmed by how nasty the lot is and feel nauseous when eating, drinking, or going to the bathroom.

Quake Zone

Icon	Description
	Quake Zone lots have to deal with the occasional earthquake. The lot will shake, and Sims will get scared and run around frantically.

Spooky

Icon	Description
	Spooky lots have many things that bump in the night at 10:30 PM. Specifically, a ghost will appear and mildly haunt Sims and scare them. Unfortunately, ghosts sometimes have a terrible habit of breaking items.

Cottage Living Lot Challenges

2 Lot Challenges

Cottage Living offers fun rural gameplay, with new farm animals, community markets, fairs, and more. The pack's lot challenges encourage players to let go of the conveniences of commercial and residential neighborhoods. Cottage Living lot challenges include Simple Living and Wild Foxes.

Simple Living

Icon	Description
	Simple Living lots do not automatically stock fridges with ingredients for every meal. Instead, Sims must grow, purchase, or fish for all food items. They will also get a positive moodlet from the fresh ingredients and learn to write a cookbook after maxing out their cooking skill.

Wild Foxes

Icon	Description
	Wild Foxes are one of the animals introduced in Cottage Living. Lots with this trait will periodically have foxes visit and wreak havoc on chickens, gardens, and wild rabbits. However, players can befriend them after a while or scare them off.

Eco Lifestyle

2 Lot Challenges

Eco Lifestyle is a different approach to Expansion packs than fans have seen in past Sims games. It focuses on nurturing the environment (or not) to change a neighborhood's eco footprint to Green, Neutral, or Industrial. Eco Lifestyle lot challenges include Landfill Lots and Reduce and Recycle.

Landfill Lot

Icon	Description
	Sims must work extra hard to get their Eco Footprint to Green with Landfill Lots. They become the town's dumping ground, and trash piles up there easily, making the Industrial footprint stronger.

Reduce and Recycle

Icon	Description
	On Reduce and Recycle lots, Sims will get the chance to recycle or compost trash, which means that outdoor trash cans will have to be manually emptied and will attract bugs if left overflowing.

Island Living

1 Lot Challenge

Island Living is all about beach life, island culture, and nature. The vast world with the Expansion pack features beautiful oceans, vibrant greenery, and even a volcano. The Island Living lot challenge is Volcanic Activity.

Volcanic Activity

Icon	Description
	Another natural disaster, lots with Volcanic Activity, will occasionally involve volcano tremors and lava rain. Steam vents may also appear, and Sims must keep their distance to avoid fire and overheating.

Jungle Adventure

1 Lot Challenge

Jungle Adventure is the only Game pack with a lot challenge. It includes a vacation world on the edge of a lively jungle with hidden temples, ancient artifacts, and native wildlife to discover. The Jungle Adventure lot challenge is Creepy Crawlies.

Creepy Crawlies

Icon	Description
	Lots with Creepy Crawlies are home to spiders, bees, and bats that will attack Sims whenever they get the urge.

Horse Ranch

1 Lot Challenge

The Horse Ranch expansion added a new animal for Sims to raise, train, and love. Owning horses is a full-time job in The Sims 4, and players can make the job even more complicated with lot challenges. Horse Ranch has one lot challenge called Wild Prairie Grass.

Wild Prairie Grass

Icon	Description
	While labeled as a lot challenge, Wild Prairie Grass can actually be handy. With this challenge, clusters of prairie grass will grow on lots, feeding horses and providing ingredients for Nectar.

For Rent

2 Lot Challenges

Players can rent houses, apartments, and duplexes to Sims with For Rent. They can play as landlords or tenants, each with its own difficulties and gameplay aspects. The two lot challenges in the pack are Mold and Maintenance Troubles.

Mold

Icon	Description
	Mold is a rather serious lot challenge in The Sims 4. Once it starts to form, it isn't long before it spreads, and Sims can even die from mold if they don't treat it quickly.

Maintenance Troubles

Icon	Description
	Lots prone to Maintenance Troubles are more likely to have rentals with issues such as electrical failures, cursed books, pool algae, and other inconveniences.
