An Accessory Dwelling Unit (ADU) is an additional, but separate living space within a single-family residential property. While the name serves to describe this type of construction, there are a variety of ways in which an ADU can be developed. Let us tell you all about the different types of ADUs.
Detached new construction
Let us start with the most expensive kind of construction by looking at a detached new construction. A separate unit will require new utility lines and adequate room for construction, Furthermore, this type of development is currently required to meet certain parking regulations in the state of California. If homeowners are able to look beyond the extra cost, detached ADU’s offer the most privacy to everyone living in the property.
Garage conversion
Depending on the kind of garage, this type of construction can be either an attached or detached ADU. However, this living space will likely be subject to the garage’s original blueprints. As a result, this type of construction is cheaper than a brand new construction.
Above a garage
While this option might sound as simple as a garage conversion, it usually presents a few more complications. For instance, most garages do not possess enough support for a second floor. Many times, the cost of reinforcing the garage to hold a second hold is quite significant. As a result, many homeowners opt for a brand new construction in place of the old garage.
Bump out
A bump out ADU is an internal conversion of the main residence. The best way to imagine it is as an extension that shares a wall with the primary house. This ADU choice is common to citations where a garage isn’t available for conversion.
Basement conversion
Basement ADUs are perhaps some of the most effective conversions possible, securing a big addition by investing a small budget. While some have the idea that a basement ADU is likely to miss sunlight due to its nature, it is possible to brighten a conventional basement with full-size windows.
Interior ADUs
While a basement ADU can also be considered an interior conversion, a strictly interior ADU consisting primarily of a section of the primary house besides the basement is converted to a secondary living space. While this might also be a cost effective way to create an ADU, it is also the form that allows for less privacy.
Attic conversion
An attic ADU is another kind of interior conversion that allows for an exterior entrance. As a result, privacy issues are likely not to be a factor in this type of living arrangement. SImilarly, loft spaces can work similarly to attic conversions.
