Upgrading buildings is one of the most important parts of progressing in Police Chief game. Every major facility has its own resource requirements, construction time, and upgrade prerequisites, and the costs become much more expensive as you move toward higher levels.
This Police Chief building construction guide covers the Cash, Ammo, Electricity, Gas, construction time, and required buildings for every main upgrade from Level 1 through Level 30. Use it to plan your upgrades in advance and make sure you have enough resources ready before starting a long construction.
The Chief’s Office is especially important because many other buildings are locked behind its level. Training facilities, the Dispatch Center, Research Center, Command Center, and other important structures also have their own upgrade requirements.
Police Chief Building Upgrade Costs & Requirements Guide
Most buildings begin at Level 1 and can be upgraded multiple times. Each upgrade consumes resources and takes time to complete. Higher-level upgrades require significantly more resources and can take several days.
The main resources used for construction are:
- Cash – Used for almost every building upgrade.
- Ammo – Becomes important for higher-level buildings, usually starting around Level 11.
- Electricity – Required for buildings once they reach higher upgrade tiers.
- Gas – Starts appearing in later upgrades and becomes increasingly expensive.
- Construction Time – The base time required to complete the upgrade before applying any bonuses or reductions.
Construction times shown in this guide are the base times. Your actual timer may be shorter because of research, buffs, construction bonuses, or other effects.

This guide covers the following main buildings:
- Chief’s Office

Security Wall
The Security Wall is different from most buildings because it only has 10 levels. Its upgrades are tied directly to specific Chief’s Office milestones.

Tips for Managing Construction
Prioritize the Chief’s Office
The Chief’s Office should generally be one of your main upgrade priorities because its level determines when many other buildings can progress. Before starting an expensive Chief’s Office upgrade, check every listed prerequisite and upgrade those buildings first.
Upgrade Required Buildings Before You Need Them
Don’t wait until you have enough resources for the Chief’s Office and then discover that another building is blocking the upgrade. Check the requirements for your next Chief’s Office level ahead of time and work toward those buildings while gathering resources.
Save Resources for Higher Levels
The resource requirements increase dramatically in the later levels. Once you reach the higher tiers, it becomes much more important to plan your Cash, Ammo, Electricity, and Gas spending instead of upgrading every available building immediately.
Use Construction Bonuses
The times in these tables are the base construction times. Research, buffs, bonuses, and other effects can reduce the actual time shown in-game. Apply construction-speed bonuses whenever possible, particularly before starting upgrades that take multiple days.
Don’t Ignore the Research Center
Research can improve different aspects of your city and may provide bonuses that make future progression easier. Keeping the Research Center upgraded can therefore be useful even when it isn’t your immediate Chief’s Office prerequisite.
Final Thoughts
Police Chief’s building progression becomes much more resource-intensive as you move beyond the early levels. The biggest mistake is upgrading without checking the next requirement and then getting stuck behind another building.
Use the Chief’s Office level as your main progression target, keep prerequisite buildings close to the required level, and stockpile the resources needed for major upgrades before starting them. Once construction times reach several days, planning your upgrade queue becomes just as important as gathering the resources themselves.
Note: The construction times listed here are base times and may differ from the timers shown in your account because of active research, buffs, bonuses, or other construction-speed modifiers.
