Phase 1

Step 1: Free ADU Space Check

Typically within 1-2 business days

Every project starts with a Free ADU Space Check.
You submit your property address, and our team completes a high-level aerial review to see if your site appears to have:

Sufficient space for an ADU

Basic delivery and access potential

Phase 2

Step 2: Site Feasibility Report ($125)

If your property appears to be a good candidate, the next step is a Site Feasibility Report.

This is a deeper, property-specific review that evaluates:

Zoning and setback requirements

ADU placement constraints

Delivery and access considerations

Potential risks or limitations

Clear next steps

Cost: $125 flat fee

Turnaround: 3–5 business days

This report helps determine whether an ADU may be possible, but does not guarantee approval or construction.
Final determinations are made by the local jurisdiction.

How Pricing Works

Mesocore offers a pre-engineered, pre-approved ADU with a fixed base price.

ADU unit price: $129,000

Installation and site work: Varies by property

While the ADU itself is a fixed cost, installation expenses depend on site-specific factors such as:

Foundation requirements

Utility connections (water, sewer, or septic)

Soil conditions

Access and delivery constraints

Local jurisdictional requirements

Because these conditions vary from property to property, total project cost cannot be accurately determined upfront.
Our process is designed to confirm these costs before you commit to construction.

Phase 3

Step 3: Financing Alignment

Before moving into permit-ready documentation and detailed cost development, we align on how you’re thinking about financing your ADU.

This step ensures the work we do next is appropriate, useful, and aligned with your goals.
At this stage, we’ll confirm whether you:

Plan to self-fund

Are interested in financing options

Would like guidance on available paths

This is not a commitment — it’s a planning conversation designed to support informed decision-making.

Phase 4

Step 4: Permit & Cost Readiness Package ($5,000)

Pre-Construction Services Agreement

Once feasibility is confirmed and financing intent is aligned, we move into our Permit & Cost Readiness Package.

This is a contracted, white-glove pre-construction step that prepares your project for permit submission and delivers meaningful cost clarity.

Depending on your property and jurisdiction, this package may include:

Site visit (if required)

Survey coordination

Soils / geotechnical testing

Permit-ready site plan

Utility and access verification

Subcontractor scope development and estimates, including:

  • Foundation

  • Water / sewer or septic

  • Masonry and flatwork

  • Site work

What you receive at the end of this step

A permit-ready documentation package

A semi-firm total project cost (ADU + site + installation)

A clear, informed go / no-go decision before construction

Fee: $5,000

Contract: Pre-Construction Services Agreement

Credit: Applied toward the total project cost if you proceed with construction

Construction is not obligated at this stage and requires a separate agreement.

Phase 5

Step 5: Permit Submission & Construction Agreement

With permit-ready documents and real pricing in hand:

Plans are submitted to the local jurisdiction

You decide whether to proceed

Final scope, pricing, and timeline are presented

If you choose to move forward, a Construction Agreement is signed and your project moves into execution.
This is where the sale occurs — based on real data, not assumptions.

Phase 6

Step 6: Manufacturing & Site Work

Mesocore ADUs are pre-engineered and pre-approved, allowing manufacturing to begin once permits are issued.

While your ADU is built off-site, site work progresses in parallel, including:

Foundation preparation

Delivery coordination

Utility connections
