LotAdjuster 2.8

Version 2.8 fixes a bug where the error "can't intersect other objects" can occur even when no such object exists.

Occupied Apartment Life apartments cannot be modified.

LotAdjuster 3.x
There is a new version of the LotAdjuster available here:

Version 3.x allows you to adjust lots in lot-sized tiles, rather than neighborhood-sized tiles. This alternate version also allows you to shift buildings on a lot by expanding one side and shrinking the other. Several other bugs have been fixed in 3.x which remain in 2.x.

Version 2.8, which adjusts in hood-sized tiles, will remain available here. It's a bit easier to use, but provides less flexibility.

The LotAdjuster allows you to modify a "Sims 2" lot in a variety of ways, including:
- Enlarge a lot up to a size of 6x6, which is the EA-imposed TS2 limit.
- Enlarge a lot over the road; allow building on both sides of the road.
- Shrink a lot; allow building to within one tile of the edge of a lot; create pseudo rowhouses.
- Move a lot within a neighborhood; move a lot away from the road.
- Add and remove roads; create a roadless lot; create a lot with multiple roads: corner lot, alleyway, service road, square.
- Unlock tiles on a lot.
- Fix vehicle and pedestrian portal locations, as well as the location of the mailbox, trash can, and phone booth.
- Fix the edges of a lot: smooth, flatten, or match neighborhood terrain.
- Fix crashing beach lots. See this link for further details:

This version of the LotAdjuster works with all expansion and stuff packs, up to and including The Sims 2 Mansion & Garden Stuff.

The LotAdjuster is the successor to the LotExpander:

- The LotAdjuster is released under the GNU General Public License.
- The program uses some DLLs from SimPE; they are included in the zip file.
- You need the Microsoft .NET Framework 2.0:

To install, just download and unzip it. Run the EXE from the unzipped location. This is "alpha" software and is still in development; it is not guaranteed to work and may corrupt your lot. Be sure to backup your game before using this tool.

I have included the source code for version 2.8 in There is no need to download this file unless you are a C# programmer who wishes to look at or modify the code.

I left the previous version ( available, in case there are any unforseen problems. There is no need to download this file.

Running under OS/X:
Please read this thread for information about running the LotAdjuster under OS/X:

At this time, there are no instructions available for the LotAdjuster; hopefully, some will be available soon. In the interim, please see the LotExpander instructions and substitute "LotAdjuster" for "LotExpander". The screenshots will be different than the LotAdjuster, but the basic method is the same.

Advanced options are changed by clicking the "Advanced" button on the lot information screen. Options in this category are more likely to require special handling. Be sure to test your lot thoroughly before sharing it.

If you have any problems with the new LotAdjuster, or if you have suggestions that you would like to see implemented, please let me know.

How to Help:
1) I'm trying to get together a list of "Search Keywords" for this post. I would appreciate people telling me what keywords they used to search for this program. This is especially useful if their initial search failed, since I can add these keywords to help other people find the LotAdjuster.

2) The LotAdjuster is a general purpose tool with a wide range of applications. The main thing that we need right now is tutorials on how to use the various features to create special types of lots. If you create a tutorial which is relevant, please post a link to your tutorial and I will include it here. Some of my thoughts on tutorials which might be helpful:

Additional Credits:
This program is derived from the LotExpander, which was designed and developed by Andi8104. Without his work, the LotAdjuster would not exist.

Thank you to all of the people who helped to make this tool a reality, including aelflaed, baratron, ebonyspiral, ikbod, Inge Jones, ingeli, KariMinger, ladykatsim, Mutantbunny, niol, plasticbox, pljones, Quaxi, and Rascal.

I'm sure that I've forgotten some people, since so many people have helped with the development of this program. If you know of someone who's been missed, it was not intentional. Please let me know and I'll add them to the list.

I just used Lotadjuster for the first time to add to a lot so I could put in a driveway. My Sims wanted a car but there wasn't enough room on the lot. Everything seemed to go well until I decided to add a garage. Alas, it wouldn't let me put a roof on the garage. So I took the garage down and my Sims have to be content with a driveway for the car. It was a Maxis house that came with Pleasantview so the problem is probably in the preset neighborhood. Thankyou for making it possible to atleast add the driveway.

Very useful indeed. Had a blast adjusting some of my lots. I messed up some of them too, hehe! Either way it's quite amusing and helpful.

This is great, it will really help me. I am glad I kept searching, as this didn't come up in my search (sims2 expand lot).

Worked perfectly apart from a few visual glitches with the lot imposter. Fixed it by repeating phase 2.
