As a trusted ADU builder serving the Santa Cruz area, OCA Builders offers a comprehensive range of construction types to suit different property layouts, budgets, and lifestyle needs.
Exploring the ADU Construction Options Available
Detached ADU: A detached ADU is a stand-alone structure built on the same property as the primary residence. This option provides maximum privacy and flexibility, making it ideal for generating rental income or independently housing family members. Think of a backyard cottage or a modern studio nestled in the garden — a true granny flat or Casita solution.
Attached ADU: An attached ADU is physically connected to the primary home but features its own private entrance. This option is often more cost-effective than a fully detached build and allows for close proximity while maintaining separate living spaces. It integrates seamlessly with the existing home structure, making it a popular choice for in-law suite configurations.
Garage Conversion ADU: As a skilled garage conversion contractor, OCA Builders transforms existing garages into fully livable units. By utilizing an already-standing structure, this approach typically reduces both construction costs and timelines. A single or double garage can be converted into a one-bedroom apartment or studio with modern finishes and full amenities.
Internal ADU: An internal ADU is created within the existing footprint of the primary residence — such as an attic space or a reconfigured section of the main home. This is a cost-effective solution that requires minimal changes to the exterior and is particularly well-suited for multi-generational living arrangements.
Junior ADU (JADU): As a capable JADU contractor, OCA Builders also constructs Junior ADUs — smaller units of up to 500 square feet built within the walls of an existing single-family home. JADUs are more affordable and quicker to build than larger ADU types, allowing homeowners to maximize their existing space without significant structural alterations. A typical example includes converting a master bedroom suite or a large room into a self-contained living unit with a small kitchen and bathroom.
