The required lots size depends on whether you are dividing a new lot or building on an existing lot. Susan is correct that you need to meet minimum requirements to create a new lot .

You can however build on a smaller lot if it was legal when it was created and you can meet minimum setback requirements. A lot that is 50 feet wide is still very buildable. Even with some caution a lot that is less than 50 feet wide may be buildable.

Do your homework before you buy the lot. Ask your Realtor and more important ask at City Hall. Go to the Zoning and Building Inspector offices and any other offices they suggest. Ask them if they know of ANY reason you would not be able to build on the lot and how you can solve the issue. If it can't be solved pick a different lot.

Existing lots in Oshkosh are limited but there are some that still exist and if you can find one they can be a good choice for your needs.

It is great that youths are getting involved in helping other. Good luck to you

Hi Brian,

Susan is correct on what our city requirements are for new construction in the city. There are exceptions with existing lots where a home has been raised. If you have a site in mind, check specifically about that lot. There are several in the inner city core that have been grandfathered.

minimum width 60 feet, minimum depth 100 feet, minimum area 7200 square feet. I've included a link to the city's zoning ordinance. Most cities now have this information available on the internet. Check out chapter 30 and the addendum.
