We see three main reasons:

  1. Maximization of your property usage

  2. Multi-family (generational) living that allows for all the benefits while maintaining some separation

  3. Combined uses and convenience 

Let's discuss the merits/benefits of each one:

  1. The largest cost in most real estate purchases is for your land. Investing in an accessary structure/ADU will yield a lower cost/square footage price to build, but generally produce an above 100% return.

  2. Multi-family usage can yield relational benefits/outcomes for families that transcend merely economic metrics.

  3. Combined uses may include rental income, home office space, storage, workshop space or even a spot for your vehicle.

We believe this trend of modifying ordinance/allowing ADU's within municipalities will continue. 

We will be updating information, related subject matter and creating news that we hope you find interesting.

Accessary Dwelling Units
Possibilities are much more than just an "in-law" space!

Basically, almost all of our projects are designed and built for accessary uses. The great part now is, in many municipalities they are admissible and permit-able for permanent dwelling use.

In municipalities where the word "dwelling" is not used, this does not necessarily mean you cannot have "dwelling" space.

Whatever your desired space usages are, our team can usually design a solution to facilitate your project. Strategies may require some type of variance or design application.

When completed, your investment will have a great ROI, be functional, flexible, and convenient and become a value add for your lifestyle needs.

Some general ordinance info

Accessory Dwelling Units

An ADU (accessory dwelling unit) is an additional, self-contained dwelling on a typical single-family lot. It can be attached, such as in the lower level of the main dwelling, or detached at the rear of the property.  These smaller units represent the “missing middle,” filling the gap between single-family homes and multi-unit dwellings downtown. While ADUs are not the sole answer to Decatur’s missing middle, they represent a big step in the right direction. Residents of ADUs contribute to the vitality of the community, and ADUs make it possible for more families to own and maintain a home in the city. 

ADUs as a housing type became effective in 2015 upon adoption of the Decatur Unified Development Ordinance. They are allowed in most single-family and multi-family residential zoning districts – R-85, R-60, R-50, RM-18, RM-22, and RM-43. One ADU per primary dwelling unit is possible if the lot conforms to the minimum size requirements of its zoning district. Other considerations: 

  • An ADU may be developed in or to the rear of an existing or new main dwelling. 

  • To keep true to its accessory size, an ADU may have a floor area up to 800 square feet, and should not exceed 40 percent of the floor area of the primary dwelling. If the ADU is combined with the garage, the total floor area may be up to 1,000 square feet.

  • An ADU may have up to two bedrooms. 

  • The owner is required to reside in either the main dwelling or the ADU for at least eight months of the year; an affidavit will be required of the owner confirming residency. 

  • If detached from the main dwelling, an ADU must be located in the rear yard and have a footprint no greater than 30 percent of the rear yard.  

  • In combination with the main dwelling, the total floor area should not exceed 40 percent of the lot area. 

  • Similarly, the total lot coverage of all impervious surfaces should not exceed 40 percent of the lot area. 

As a housing option, ADUs demonstrate the values of diversity and affordability promoted by the City of Decatur. They serve to fill a gap in Decatur’s housing market by providing a new, neighborhood scale rental housing option for those looking for affordable living arrangements in a more traditional single-family-home setting.
