You’ve spent three hours meticulously detailing a custom interchange. The traffic flows like a dream. Then, suddenly, those annoying little blue icons start popping up over your residential zones. Too few services. It’s the bane of every mayor's existence in Cities: Skylines. You look at your budget, you look at your map, and you think, "I literally just placed a police station right there."
Honestly, it’s frustrating.

The game doesn't always tell you which service is missing. It just gives you that vague, judgmental bubble. Most players assume they just need more hospitals or schools, but the logic under the hood of Colossal Order’s simulation is a bit more finicky than that. It isn't just about physical proximity; it’s about the "service coverage" mechanic and how it interacts with building leveling.
The Mystery of the Too Few Services Cities Skylines Warning
Basically, every building in Cities: Skylines has a hidden "experience bar." As you provide more amenities, the building levels up. Higher levels mean more taxes and wealthier citizens. But if a building is ready to hit Level 5 and you haven't given it enough "points" across various service categories, you get the too few services Cities Skylines error.
It’s a check-and-balance system. The game is essentially saying, "Hey, this skyscraper is too fancy to only have a single bus stop and a landfill nearby."
It's Not Just Police and Fire
When people see "services," they immediately go for the big three: Fire, Police, and Health. While those are foundational, they often aren't the culprit for mid-to-late game complaints. You've probably already got a fire house on every corner.

The "hidden" services often include:
- Education: Even if you have capacity, the physical distance of the school matters for the "land value" boost.
- Public Transport: This is the big one. Buildings get a massive service score boost from having a bus stop, metro station, or tram line within a few blocks.
- Entertainment/Parks: If your residents have nowhere to walk their digital dogs, they’ll complain about services.
- Deathcare: This is a classic "silent killer" of city happiness. If hearses can't reach a building because of a one-way street or heavy traffic, the "service" isn't being delivered.
The Logic Behind Service Coverage
There's a distinction between "service range" and "service effect."
When you place a building, you see those green roads. That's the primary range. However, the benefit of that building often extends further, albeit at a lower intensity. If you’re seeing the too few services Cities Skylines notification, it usually means the building is sitting in a "yellow" or "uncolored" zone on the service overlay.
Traffic is the secret enemy here.
You can have forty police stations, but if they are all stuck in a massive jam on the industrial highway, the service "score" of your residential district drops. The game calculates how effectively a service vehicle can reach the destination. If the pathing is blocked or too long, the building won't receive the "service points" it needs to satisfy the requirement for its current level.
Why Parks are Actually "Services"
In the game’s code, parks aren't just for looks. They function as a "passive service." If you’re struggling with the too few services error in a high-density area, try dropping a Small Park or a Plaza.

Oftentimes, this provides just enough of a land value bump to clear the icon. It’s cheaper than a hospital and requires no maintenance vehicles to navigate traffic.
High Density vs. Low Density Requirements
Low-density suburban houses are pretty chill. They don't need much. A school nearby and a trash pickup once a week keeps them happy.
High density is a different beast entirely.
Once you start zoning high-density residential or commercial, the "service threshold" skyrockets. A Level 5 high-density residential building requires almost every single service type to be present and efficient. If you forget to include a library or a post office (if you have the Industries or Financial Districts DLCs), the building might stall or give you the error.
The Post Office Trap
If you have the Industries DLC, the Post Office becomes a vital service. Many players forget this. They build a sprawling metropolis and ignore the mail system. Suddenly, half the city is complaining about services.
Check your mail overlay. If your sorting facilities are overwhelmed or your post vans are stuck in traffic, that's your "too few services" culprit right there.
Troubleshooting the "Too Few Services" Icon
- Check the Leveling Progress: Click the building. Look at the bar at the bottom. If it's flickering or the building is trying to level up, it needs more service points.
- The Transport Hack: Place a bus stop directly in front of the complaining building. Wait ten seconds. Often, the icon disappears immediately. Public transit is one of the highest-weighted "services" for building leveling.
- Check for Death: Use the Deathcare overlay. Are there dead bodies waiting for pickup? A building with a corpse in it for too long will trigger a service warning before it eventually abandons.
- Listen to the Chirper: Seriously. Sometimes the annoying bird actually gives you a hint. If citizens are talking about "smelly trash" or "fear of crime," you know exactly which service is failing.
Real World Example: The "Crematorium Crisis"
I remember a city I built where a whole district of high-rise apartments started flashing the service icon. I had plenty of clinics. I had a massive police headquarters. I had a high school right across the street.
I couldn't figure it out.
I zoomed in and realized my crematoriums were all located on the other side of a bridge that was currently experiencing a 90% traffic bottleneck. The hearses couldn't get through. Because the "deathcare service" wasn't reaching the buildings, the game flagged them for too few services. Fixing the bridge didn't just fix traffic; it satisfied the service requirement for 50,000 people.
Cargo and Commercial Services
For commercial zones, "services" includes the delivery of goods. If your shops can't get deliveries from your industrial zones or cargo hubs, they will eventually complain. While this usually manifests as "Not enough goods to sell," it can sometimes contribute to a general lack of service satisfaction if the underlying land value is also low.
Actionable Steps to Clear the Icons
Stop spamming expensive service buildings and try these targeted fixes instead:
- Diversify your parks. Don't just use the same "Park with Trees" over and over. Use different types of plazas and recreational spots to maximize the "entertainment" service score.
- Optimize your transit lines. A metro line with high frequency is worth more "service points" to a building than a distant hospital.
- Check your budget. If you've lowered the budget for a specific service to 50%, you've effectively reduced the number of vehicles and the "green range" on the roads. Bump it back to 100% (or 150% at night) to see if the icons clear.
- Use Policies. The "Big Town" or "High Tech Housing" policies can influence how buildings react to services, though they usually increase the requirements rather than lowering them.
- Upgrade your roads. Sometimes, adding decorative trees to a road increases the "land value" which counts toward the service threshold for leveling up.
The too few services Cities Skylines warning is basically a puzzle. It’s the game telling you that the infrastructure hasn't kept pace with the ambition of your zoning. Look beyond the basics—check your mail, your buses, and your hearses. Usually, the solution is a simple bus stop or a better-placed crematorium.
