Our Process: Your ADU, Built with Ease and Confidence

At Contemporary Tiny Homes, we make building your ADU simple and stress-free.

We'll handle all aspects of the process for you, from designing your custom home, obtaining all necessary permits from your town, preparing the construction site, doing all the excavation and building your foundation, doing the permanent connections to all utilities (water, sewer and electricity) and building your home including interior & exterior finishes, and all bathroom, kitchen & lighting fixtures.

Phase 1: Feasibility & Design

Timeline: Less than 1 Month

We start by working closely with you to finalize the design and specifications of your ADU. During this phase, you’ll:

Choose colors, flooring, cabinetry, fixtures, and lighting.
Make slight adjustments to the floor plan, with options for larger changes if needed (costs may vary).

We’ll coordinate a site survey to evaluate your property. For homes with wells or septic systems, additional engineering may be necessary to assess water and sewer capacity.

Phase 2: Permit Application

Timeline: Typically a Month or Two

Once your design and site survey are complete, we’ll prepare and submit all necessary documentation to obtain the required permits from your local authorities. This includes:

Site survey data.
Finalized plans and specifications.
Any required engineering reports.

All required Construction Documents (CDs).

While permit timelines vary depending on your town, we handle the process efficiently to keep your project on track.

Phase 3: Construction

Timeline: Approximately 3–4 Months

This is where your ADU starts to take shape! During construction, we:

Prepare the site by installing a tracking pad, dumpster, and portable facilities.
Excavate and pour the concrete for the foundation.
Frame the structure, add the roof, siding, doors, and windows.
Complete interior work, including plumbing, electrical, HVAC, insulation, drywall, flooring, and finishes.
Install cabinetry, countertops, fixtures and, as an option, appliances.

The result? A fully finished ADU, ready for move-in!

Phase 4: Final Walkthrough & Delivery

Timeline: Approximately 1-2 Weeks

Before handing over the keys, we invite you to a final walkthrough of your new ADU. This allows us to:

Ensure every detail is completed to your satisfaction and as agreed upon.
Make any final adjustments needed.

Once approved, your ADU is ready for you to enjoy!
