ACCESSORY DWELLING UNIT

Smart Additions. Endless Possibilities.

OUR PROCESS:

Every project starts with a conversation. Whether you reach out via phone, email, or referral, we take the time to understand your vision and ensure we’re a good fit from the beginning.

1. Intake

Next, we send a brief questionnaire to learn more about your goals, style, timeline, and expectations—helping us prepare for a focused consultation.

2. Questionnaire

We meet to review your ideas, sketches, or plans, evaluate the site, and discuss your goals. You’ll receive an early cost range based on the project scope.

3. In-Person Consultation

Next is to sign a Pre-Construction Agreement (PCA)— this crucial step ensures your project is accurately planned, thoroughly estimated, and set up for success. The PCA allows us to invest time and expertise into your project before construction begins, so you can move forward with confidence—knowing the scope, budget, and design are fully aligned. 

4. PCA

During this phase, we finalize layout details, refine material selections, and coordinate with our trusted network of suppliers and trade partners. We’ll also collaborate on design elements, permitting needs, and timeline expectations. Your custom estimate will include a comprehensive scope of work, budget, and material specs. Our shared goal is to finalize a plan that’s thoughtful, clear, and ready to build.

5. Planning & Estimating

Once your final estimate is approved, we’ll present the Construction Contract for mutual signature. This agreement outlines the total project cost, payment schedule, and key construction details. We’ll review it together for clarity and alignment. 

6. Construction Contract 

After signing the construction contract, we’ll invoice you for the initial construction deposit. We then confirm city permits, engage with trade partners, vendors, and craftsmen, and source products tailored to your project. A construction schedule will be established based on deposits and selected products from the Pre-Construction Agreement. 

7. Coordinating the Build 

This is where the magic happens. We’ll stay in close communication—offering weekly progress updates if you’d like—and make sure you’re never left guessing. Adam remains hands-on in the field, ensuring quality craftsmanship and problem-solving along the way. We aim to make the experience efficient, positive, and minimally disruptive to your day-to-day life.

8. Building your Dream 

If changes are needed, we’ll issue a Change Order outlining the impact on cost, timeline, and coordination. You’ll always know what to expect—no surprises.

9. In-Process Changes 

We conduct a full walkthrough with you, testing systems and addressing any punch list items. You’ll receive a full clean up, final documentation, a one-year craftsmanship warranty, and post check-ins at three and eleven months.

10. Project Hand Over 

Smart Additions. Endless Possibilities.

If you're looking to maximize your property’s potential, an Accessory Dwelling Unit (ADU) is one of the smartest investments you can make. At Hall Builders Inc., we specialize in designing and building custom ADUs that are as functional as they are beautiful—perfect for rental income, multigenerational living, guest accommodations, or a private home office.
