Most single-family homes in California can build an ADU if your lot meets zoning, lot size, and setback requirements. Eagle ADU can quickly check your property and estimate your ADU potential.

ADU costs vary by size, model, and site conditions. A studio ADU typically starts around $230K, a 1-bedroom around $300K, and a 2-bedroom ADU can go $360K+. Eagle ADU provides detailed cost estimates based on your lot. Starting prices reflect standard lot conditions, mid-range finishes, and typical East Bay permitting. Your free feasibility visit will include a realistic project estimate specific to your property.

Eagle ADU installations usually take 90–120 days from permit approval to move-in.

We offer three refined ADU models designed for efficient permitting, predictable pricing, and faster delivery: Eagle Studio ADU – 400–500 sq ft Eagle One-Bedroom ADU – 600–700 sq ft Eagle Two-Bedroom ADU – 800–900 sq ft Each model features designer-curated interior and exterior finish collections, with select options for colors, materials, and upgrades—delivering a high-end result without slowing the process. We focus on executing these proven designs at a high level. Custom projects may be considered selectively and will require additional time and investment. This approach is ideal for clients who value quality, efficiency, and a streamlined building experience.
