Frequently Asked Questions
Do I need a permit for a garage conversion or ADU?
Yes, permits are required for any accessory dwelling unit, including garage conversions and detached backyard structures. The permitting process ensures compliance with Dublin’s zoning, safety, and structural regulations. As a leading ADU builder in Dublin, we handle all permit applications, revisions, and communications with the city on your behalf. Our familiarity with local codes streamlines approvals and minimizes delays.
How much does it cost to build an ADU in Dublin?
The investment for a secondary living space varies based on size, design complexity, and site conditions, with most projects starting in the low six figures. Significant factors include foundation work, utility connections, interior finishes, and permit fees. During your initial consultation, we provide a transparent estimate and explore options to align the project with your budget. We also advise on financing strategies to make the addition more affordable.
What is the difference between a junior and full-sized addition?
A junior accessory dwelling unit is typically less than 500 square feet and is located within the main home, which often features a kitchenette and a private entrance. It shares utilities with the primary residence and is ideal for single occupancy or extended family. In contrast, a full-sized space is usually a separate structure with its kitchen, bathroom, and living space. These upgrades offer greater independence and are suited for long-term rental or multigenerational living.
How long does it take to build an ADU?
The average timeline for accessory dwelling unit installation ranges from 3 to 5 months. This includes planning, permitting, and construction phases. The exact duration depends on the type of addition, site conditions, and permitting complexity. We provide a detailed schedule upfront and manage progress to stay on track.
Can an addition be integrated with a broader home upgrade?
Yes, as your ADU Builder in Dublin, we can integrate the project with a larger home remodeling service for a seamless and cost-effective approach. Many of our clients choose to improve their kitchens, bathrooms, or layouts while adding to their homes. Doing both at once can reduce disruption and create a more cohesive property design. We’re happy to coordinate these efforts under one comprehensive plan.
