Ordinance

This article is about the game concept. For file format in savegame files, see Ordinance Subfiles.

In SimCity 4, there are exactly 20 ordinances which you can enact, and 19 that have an effect on your city. All ordinances are predefined in the game's executable. Existing ordinances can be replaced or modified to a certain degree, but new ordinances cannot be added due to this limitation.

Ordinance exemplars have their own Type and Group IDs, 6534284A and A9C2C209 respectively. Every language has a separate name for each ordinance. The ones in the table below are from the UK English version of SimCity 4, and listed in alphabetical order of their Exemplar Names, as listed in SimCity1.dat.

There are two known unused properties in the Ordinances, the year they became available in (presumably) an Alpha version of the game and only edited from 0 in the Power Conservation Act, and the "Monthly Chance", which is set to 0.5 in all Ordinances.

City eligibility for ordinances is re-evaluated every month.

Availability

All ordinances become available after one in-game month, except four, which have prerequisite buildings which must be built first. Their in-game names and their required buildings are listed both below and in the table.

• Junior Sports Programs (Park)
• Landfill Gas Recovery Program (Landfill + Gas Power Plant)
• Neighborhood Watch Program (Police Station)
• Trash Presort Requirement (Recycling Center)

Benefits, Detriments and Costs

This table contains all of the ordinances in the game defined by Maxis and their effects. In-game names are as they appear in the UK Englsh (British English) version of the game.

Mayor Rating alterations are not in percent, as the Mayor Rating is defined as a number from 1 to 255, and subtract from that number. For example, "Decreased by 5" means the Mayor Rating is decreased by exactly 5, not 5%.
