ADU Types We Design in Anaheim
Spanish-Style ADU
A Spanish-style ADU complements many Southern California homes with stucco exteriors, clay tile accents, and arched details. This design approach balances timeless curb appeal with modern structural and energy standards.
Thoughtful proportions and durable materials ensure the unit feels cohesive with the main residence while delivering long-term performance.
Studio ADU
A studio ADU offers compact, efficient living ideal for rental income or guest accommodations. Smart layouts integrate kitchen, living, and sleeping zones without sacrificing comfort.
Built-in storage and strategic window placement help smaller footprints feel open and functional, making this option practical for many Anaheim properties.
Cottage ADU
A cottage ADU creates a welcoming, independent living space with charming architectural details and efficient interior planning. Gabled rooflines, inviting entryways, and durable finishes provide character while supporting everyday functionality.
This style works well in established neighborhoods where scale and visual harmony matter, carefully balancing privacy and connectivity to outdoor areas.
2 Bedroom ADU
A 2-bedroom ADU supports families, caretakers, roommates, or extended stays with clearly defined private and shared spaces.
Efficient circulation separates sleeping areas from the main living zone, enhancing comfort. Well-planned kitchens and bathrooms ensure the layout functions like a small home rather than a secondary unit.
3 Bedroom ADU
A 3-bedroom ADU maximizes living capacity for larger households or long-term rental strategies. Expanded common areas and carefully placed bedrooms create flexibility for changing needs.
We optimize flow, privacy, and sound attenuation while meeting structural and energy standards so that the unit feels as solid and quiet as a main residence. This option adds substantial utility and value to qualifying properties.
Garage ADU
A garage ADU transforms underused square footage into a fully functional residence. We evaluate structural integrity, slab condition, insulation, and fire separation requirements before redesigning the space.
With proper upgrades and thoughtful planning, an existing garage can become a comfortable, code-compliant living environment for family or a high-performing rental unit for extra income.
Junior ADU
A Junior ADU converts interior space within the primary residence into a self-contained unit. Often created from an existing bedroom or portion of the home, it includes a kitchenette and separate entrance where permitted.
This option can be ideal for a caregiver, aging family member, student, or starter rental for supplemental income without expanding the home's footprint.
Our Straightforward Approach
Building an accessory dwelling unit in Anaheim should always be an organized and predictable process.
We begin with a feasibility review that evaluates zoning, setbacks, lot coverage, utilities, and your long-term goals. From there, we develop tailored plans and clear investment ranges before managing permit submissions and plan-check responses with the city.
Once approved, we coordinate with trusted builders and remain involved through key milestones, keeping your Anaheim ADU on schedule, compliant, and aligned with your expectations.
