Form & Function: ADU Builders and Carriage House Specialists
Form & Function is a contractor that specializes in building custom Accessory Dwelling Units (ADUs) and restoring original Carriage Houses. Their approach combines traditional design aesthetics with the practical demands of modern living, resulting in secondary dwelling spaces that are both functional and architecturally considered.
As an experienced ADU builder, Form & Function manages the entire construction process from start to finish. This includes new construction of detached ADU structures, home additions that create separate living quarters, and conversions of existing spaces — such as garages or basements — into independent dwelling units. They also work on detached garages with apartment space above.
What Is an Accessory Dwelling Unit?
An accessory dwelling unit is a legal term for a secondary house or apartment that shares a building lot with a larger, primary residence. The unit cannot be bought or sold independently from the main property. ADUs are commonly used to generate rental income or to provide housing for a family member, such as an elderly parent who might otherwise need to move to an assisted living facility.
ADUs are known by a variety of names, including:
- In-law apartment or in-law suite
- Granny flat
- Carriage house
- Backyard cottage
- Casita
An ADU can take several forms, such as a newly constructed stand-alone structure, an addition to an existing home that creates a separate living quarter, a garage conversion, or a detached garage with an apartment above. Form & Function has experience across these different ADU types.
Reasons to Consider Building an ADU
There are several practical reasons homeowners choose to add an accessory dwelling unit to their property:
- Generate rental income — A separate unit can be rented out to provide an ongoing revenue stream.
- House relatives — An in-law suite or granny flat offers a private living space for family members while keeping them close.
- Flexibility — An ADU allows homeowners to adapt to changing life circumstances without needing to relocate.
- Maximize property investment — Adding a secondary dwelling unit can increase the overall value and utility of a property.
- Provide housing — ADUs contribute to local housing availability in a meaningful way.
Form & Function approaches each ADU project as a distinct build, tailored to the specific needs and preferences of the homeowner. Their focus is on delivering a finished unit that serves its intended purpose while fitting naturally within the existing property.
