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.

Default Corner Lots

Take a look at the EA/Maxis-created Broke house in the Pleasantview neighborhood which is shipped with the game. If you try moving the house, you will notice that it requires two intersecting roads before you can place it. There is a road at the front of the house, which has the mailbox, and another road on the left side of the lot (as seen from the front).

Each lot has the ability to have up to 4 roads on the lot, one in each direction. Each road takes up a row of the lot which might otherwise have been used for building, but can now be used for vehicle and pedestrian traffic.


Sorry, I missed the question about how to create a corner lot...

First, you need to have space for the additional road on the right or left side of the lot. If your lot doesn't have adequate space, be sure to specify that you want to expand by 1 the side with the new road.

Now, to add a road to a lot, click on the "Advanced" button on the lot information screen. Click on "Add and remove roads". You will see that the Road checkmarks become enabled. Usually, the road for "Front yard" will be checked, and all of the other roads will be unchecked. Click on the road checkbox for the right or left side of the lot. (See attached picture.)

Click on next and the LA will expand your lot (if requested) and add the new road.

Be sure to edit the lot and move it in the neighborhood, as specified in the old LotExpander tutorial.

A corner lot is a lot that has two roads, e.g. in front and on the left side.

(Mootilda explained it better .. we crossposted)

Mootilda: maybe you shoud say more explicitely in the OP that the LA supports lots with *multiple* roads? "Add and remove" perhaps sounds too much like "add/remove the one road there is" because people can't imagine a lot with more than one road (can't blame them -- this is new) .. for example,

"Add and remove roads; create a roadless lot; create a lot with two or more roads: corner lot, alleyway, service road, square .."

Remove everything from the area to be trimmed, plus one additional tile at the edge of the new lot. Then rerun the LotAdjuster.

..uh what? D:

I built everything 1 click away from the last tile, and then i added a roof.. can it not be built to the last tile?

You should be able to build a roof to 1-tile away from the new edge of the lot. However, you cannot build a roof on the outer tile.

If you'd like me to take a look at your lot, please attach the pre-shrunken lot here and I'll see whether I can figure out what the problem is.
#35 Old 21st Apr 2008 at 3:32 AM
Nah, I got it, it turns out.. that it was a very very silly mistake. The lot in-game is 2x3 and the lot as told by the Lot Adjuster was 3x3 (because it counts the road), so i clicked -1 on each of the things and it kinda freaked out because I made the lot.. just the lot, without a road. xD

No problem with the Lot Adjuster, just with my brain. :p

Um, when I open the lot adjuster I can only see the left half of the screen and there's no way to drag the frame or expand it. Have I done something wrong? (I've re-downloaded twice and am still getting the same thing)
#37 Old 21st Apr 2008 at 12:15 PM
If you want to do shrinking (or the other more risky features), press the button labelled Advanced - that will open up the other half of the screen.

Wow, this seems like something really cool to play with, now I can have houses up on a tall hill, with a dirt road leading to it. Thanks so much for this, it looks like it took a lot of hard work to make. I don't know where some people just get the brains for starting a full blown project like this, you're pretty smart, Mootilda!

In this case, I do have a question. When I opened up the zip, there were all kinds of plugins and things. What do I do with those plugins? Do they go into a special folder of some sort?

Just create a folder somewhere on your hard drive and unzip everything in the zip file into that folder. Run the EXE file from that folder and it will be able to find everything that it needs.
#41 Old 22nd Apr 2008 at 1:45 AM
Sparklesim, it's best to unzip into a subfolder. You don't need to do anything with all those files, just keep them together. When you want to use the LA, click on the exe icon. You might like to make a shortcut to that file, and then you won't even have to open the subfolder to use the LotAdjuster.

Mootilda, I love you! I always wanted to build lots away from the road (rural lots just don't work next to a public road).

I was just wondering, if you package the lot which is away from the road in your game, will whoever downloads have to use this program to set it away from the road?

Thanks in advance, Wil xx :D
#43 Old 22nd Apr 2008 at 1:47 AM
Wil, you'd have to give the downloaders direction on what to do with the lot, yes. They would need to install the lot normally, then use the LA to shift it themselves.

Because the LotAdjuster has so many advanced options, it's a bit difficult to answer your question without knowing specifically what you intend to do to your lot. Are you leaving the standard road unmodified at the front of the lot? If so, then the lot should be shareable in the usual way. If people want to move your lot away from the road, then they can use the LotAdjuster to move it, just as you did.

But, if you are overwriting the road with a "country road" texture, or removing the road at the front altogether, then the lot may not be shareable in the usual way.

Above all, you should be sure to test this yourself and make sure that things are working the way that you expect them to: ie, package your lot, create a new test neighborhood, install the packaged lot, and then try placing the lot into your test neighborhood. Make sure that it can be placed and moved in the way that you want.

Before sharing any lot, you'll want to go through the experience that the people who download your lot will have, so that you know that it will work and so that you'll be able to answer their questions.

may also take note on the values you used for the lot to be away from the road, and notify downloaders about it.

#47 Old 22nd Apr 2008 at 6:40 PM Last edited by Mootilda : 13th Jan 2010 at 11:16 PM. Reason: Intermittent OS X (MAC) crash-on-load
Default Known Issues

1) When moving a pool with rounded edges, the rounded edges will not move. For now, just delete the rounded edges before expanding or shrinking the lot and add them back to the pool in the new location once the modification is complete. If you accidently expand or shrink a lot without removing the rounded edges, the lot can be fixed using the normal build tools; however, it is more difficult than just removing them beforehand.

2) If a lot is occupied during expansion or shrinking, you may notice that your sims are not in their expected locations on the lot. If your sims are using an object, such as sleeping on a bed, the object may also appear in an unexpected location. If you run the game, the sims (and associated objects) should "jump" back to their correct locations on the lot after a few seconds. I am investigating this problem.

3) There is an intermittent MAC OS X crash-on-load with shrunken lots which meet BOTH of the following criteria:
1. The lot has a perpendicular wall on one edge;
2. The lot has a length of 4 units (including the road).

Which edge the wall has to be on in order to crash depends on the U11 value of the lot:
U11 = 0: left
U11 = 1: front
U11 = 2: right
U11 = 3: back

U11 corresponds to the sun direction:

Here is plasticbox's report of the issue:

Other Issues:

1) Expanded terrain takes its form from the terrain at the edges of the existing lot. This does not always produce the desired result, especially for hilly terrain and beach lots. I am investigating whether the LotAdjuster can use the actual neighborhood terrain for the additional land. Resolved.

2) Shruken terrain takes its form from the existing lot terrain. If the edge of the newly shrunken lot is located on bumpy terrain and the "Keep Lot Edges" option is selected, then a blue tear or disconnect can result at the edge of the lot. Resolved.

3) Some of the advanced options can modify your lot so that it requires special handling. For example: roadless lots and lots which are built "over the road" cannot be picked up and moved in-game, and cannot be packaged and shared normally. This is because the Sims 2 game requires a neighborhood road for the lot to "snap to". Be sure to keep your backup until you are certain that the modified lot is functioning as you want it to.

For more information, please see this post:

4) Restrictions on Shrinking: The LotAdjuster will not allow you to shrink a lot if there is anything in the outer tile of the shrunken lot, because shrunken lots with walls at the edge of the lot (rowhouses) have proven to be unsafe. After shrinking, you should be able to add fences and objects to this outer tile from within the game. I am looking into minimizing the restrictions on shrinking, while still ensuring that shruken lots are safe.

If you want to share a shrunken lot, please tell people that your lot has been shrunken using the LotAdjuster, and give them a link to this upload thread. Although the shrinking feature has been well-tested and I believe that these lots are safe, I would like to be able to track any future problems.

5) Beach lots have special EA-imposed areas within the lot, such as the beach area and the water area. Because of this, there can be issues with beach lots which are shrunken in particular ways. For example: the water occurs on the side of the lot furthest from the road; if you shrink a beach lot at the back, you will obviously lose the water. The beach area is the row next to the water, if you shrink a beach lot too much at the front, you can remove all buildable areas.

As well, beach lots are very finicky about their placement within a neighborhood; shrunken beach lots are equally finicky. Be aware that you can shrink a beach lot so that it has different requirements than the standard beach lots.

Another issue with beach lots is the beach portals. There is one beach portal on every tile at the water's edge. Before shrinking a beach lot, I recommend that you use the Portal Revealer to remove unnecessary beach portals from the area to be trimmed.

Please see the research thread for further information on shrinking beach lots:

6) A new driveway may rotate when you try to place it after an adjustment. To solve this, be sure to snap the lot to the road in the neighborhood view after an adjustment.
