HousingWiki is a open resource for gathering, developing, and discussing housing and land-use issues. Particularly, to gather ideas, research, and strategies for creating more inclusive, affordable, equitable housing and communities. It was formerly YIMBYwiki, and began as an affiliate project of YIMBY Action, which is a member of the SFYIMBY coalition, San Francisco.
Build the most usable, complete, and open online resource for understanding housing and land-use issues, and for working to create more inclusive and affordable communities.

"yes, 'let the front lines build the strategies, we will systematize & internationalize.' is YIMBYwiki's imperial design."
YIMBYwiki was supported in 2017-18 by a grant from Better Boulder and Boulder Area Realtors Association. We invite further financial support to continue and expand this project, please contact us at editor (at) yimby.wiki if you're interested.
to-do items and proposed or planned developments.
This project grew out of a October 2016 discussion on the YIMBY Town mailing list (US national YIMBY email list/forum): "The Opposition in Portland has Arrived" (subsequently moved to "YIMBY knowledgebase/wiki (was The Opposition in Portland..). in October 2016.
As noted in thread, there have been various previous discussions about idea, and prior related efforts such as the YIMBY Sweden's YIMBY Wiki (see also English version via Google Translate), and the SFBARF FAQ created by San Francisco Bay Area Renters Federation) on Reddit. In 2014, San Francisco housing-finance expert (and SFYIMBY friend!) Fay Darmawi suggested a "HousingWiki" in her article "How Affordable Housing Can Make a Name for Itself (and Why)” (Affordable Housing Finance, March 19, 2014).
On YIMBY Town list, Mike Schiraldi (San Francisco) wrote:
"I don't want to get off on too much of a tangent, but one of the reasons it's so exciting to see nationwide YIMBY collaboration is that we can jointly build up a body of answers to frequent objections (both good-faith and bad-faith)....Any suggestions as to what sort of storage system might work for such a knowledgebase?"
Following on these conversation, SFYIMBY member Tim McCormick proposed and launched YIMBY.wiki, and continues to lead its development.
In the 2016 mailing-list discussion about starting this project, we debated between branding it with YIMBY vs leaving it more general such as Housing Wiki. The conclusion was to go with YIMBYwiki at least initially, on the idea of orienting to an inside/core community first and perhaps broadening later. So, the late 2019 decision to transition YIMBY.wiki into Housing.Wiki was sort of fulfilling an idea there from start.

Manual backup procedure
Note, backup currently running automatically daily using a Crontab job on server, except for the part of transferring backup files back to a personal account for personal and Google Drive backup copy. But if you need to do it manually or reset up the Crontab job, below are the commands, shown prefaced by the shell prompt '%':
% ssh firstname.lastname@example.org
now enter password for account 'yimbywiki'.
% php yimby.wiki/maintenance/dumpBackup.php --full | gzip > ~/backup/wiki-yimby_wiki-XML-$(date +%Y%m%d).xml.gz
that puts a date-labeled backup file X.xml.gz into /backup
% cd backup % tar -zcvf "$(date '+%F').tar.gz" /home/yimbywiki/yimby.wiki % mysqldump -u yimbywiki --password=XXXXXXXX --host=mysql.yimby.wiki yimby_wiki -c | gzip > ~/backup/wiki-yimby_wiki-$(date '+%Y%m%d').sql.gz
[note: replace XXXXXXXX with real database password].
To then retrive these backup files to personal computer, to store backups there and automatically on Google Drive:
Open terminal window.
Change to correct local directory, e.g.
% cd ~Users > tim > Google Drive > Tim > YIMBYwiki > site-backup
Now sftp to server:
% sftp email@example.com sftp> cd backup sftp> get [1st backup file just created] sftp> get [2nd backup file just created] sftp> get [3rd backup file just created]
These will then in turn get backed up automatically by Google Backup and Sync / Google Drive, at least on Tim's computers.
