MINIMUM LOT SIZE (MLS)/MINIMUM BUILDING LINE(MBL) ORD.

Building set backs and lot sizes are often defining features of a neighborhood, giving blocks a certain look and feel. Neighborhoods inside the 610 Loop that want to preserve this aspect of their character may want to explore using the Minimum Lot Size or Minimum Building Line application. In order to qualify, your neighborhood must not have deed restrictions that address lot size or building lines for all properties within the subdivision.

What is a Minimum Lot Size (MLS)?

Related Development Regulations Links (Each section has additional links)

A special minimum lot size is the minimum lot size standard currently met by at least 70% of the application area.  Applications from City designated Historic Districts use the slightly lower threshold of 60%.  By establishing this standard, lots cannot be subdivided below the “special minimum” lot size in the designated area.  For instance, if 5,000 square feet was established as the special minimum lot size, a lot could not be divided into lots smaller than that size.

If your lot is already smaller than the special minimum lot size, you will not be penalized. Existing structures may remain and can be replaced at any time without special permission.  New structures that conform to the platting and building codes may be constructed without special permission.

What is a minimum building line?

Similar to the lot size, a minimum building line, or setback, is the minimum building line currently met by at least 70% of the structures in the application area.  Applications from City designated Historic Districts use the slightly lower threshold of 60%.  Once established, structures must be constructed behind the minimum building line.
If the home on your lot is closer than the minimum building line, you will not be penalized. The existing structure may remain in place; however, any new structure on the lot must conform to the established minimum building line.

How long does this designation last?

20 years from the date City Council adopts an ordinance establishing a minimum lot size or building line.
