Milestone 2:
Procure Project Materials

Overview

Now that the contract is signed, we shift into planning and purchasing mode. During this milestone, we schedule the first round of trades—excavation, foundation, underground plumbing, and electrical—and begin ordering all the long-lead materials your project needs, from windows and doors to framing lumber and specialty plumbing fixtures. Getting ahead on materials means fewer delays down the road.

What to Expect

We’ll be ordering materials on your behalf

Items like windows, doors, sill pans, framing materials, shower pans, and specialty plumbing fixtures will be ordered during this phase. Some of these items have long lead times, so ordering early keeps us on schedule.

Material deliveries may arrive at the jobsite

You might notice deliveries showing up at your property. We coordinate this carefully, but if anything seems out of place or is blocking access, just give us a text and we’ll sort it out.

You may be contacted to confirm selections

If there are any final decisions on finishes or fixtures that haven’t been locked in, this is the time we’ll reach out. Quick responses help us stay on track with ordering.

This phase typically takes about 10 days

Most of this work happens behind the scenes, so your day-to-day won’t be disrupted yet. We’re simply getting everything queued up so construction can start smoothly.

Milestone 3:
Break Ground

Overview

This is the exciting one—construction officially begins! We’ll walk the site with you, set up all the necessary equipment and safety measures, and then the real physical work gets underway. Existing structures may be demolished, trees removed if needed, and the site is cleared, graded, and excavated. Utility trenching follows. By the end of this phase, the ground is shaped and ready for your foundation.

What to Expect

We’ll do a site walkthrough with you before anything starts

Before a single shovel hits the dirt, we’ll walk the property with you to review the plan, answer questions, and make sure everyone is aligned. This is a great time to point out any concerns about access, landscaping, or neighbors.

The jobsite will change dramatically

You’ll see a porta potty, signage, cameras, and a job box appear on-site. These are standard construction setup items. If anything is placed in a spot that causes an issue for you, let us know and we’ll adjust.

Expect noise, heavy equipment, and dust

Excavation, demolition, and trenching involve heavy machinery and can be loud. Work typically happens during standard business hours on weekdays. If you have sensitivities or special timing needs (like a work-from-home schedule), text us so we can coordinate.

There will be extra dirt and debris

Excavation and trenching generate a lot of displaced soil. We do our best to manage it, but if dirt or debris is piling up in a way that blocks access or causes an inconvenience, just text us and we’ll organize a cleanup.

Utility locating will happen (811 call)

Before we dig, we’ll have underground utilities marked. You may see spray paint or flags on your property—this is standard safety procedure and temporary.

Your neighbors may notice the activity

If you’d like, we can provide a brief note to share with your neighbors to let them know about the project. We would also be happy to communicate them with directly on a shared email. A heads-up goes a long way in maintaining good relationships during construction.

An invoice will be sent at the end of this phase

Once the site is excavated and ready, we’ll send Invoice 02 per your contract’s payment schedule.

Milestone 4:
Foundation

Overview

With the ground prepared, we now build the foundation your ADU will stand on. This is a detailed, multi-step process involving formwork, rebar, underground plumbing and electrical, several inspections, and finally the concrete pour. It’s one of the longer milestones, but every step is critical to ensuring your structure is solid and code-compliant from the ground up.

What to Expect

Multiple inspections will take place

The city and our structural engineer will visit the site several times during this phase to inspect formwork, underground utilities, rebar placement, and the pre-pour setup. These inspections are required before we can pour concrete and occasionally cause brief scheduling pauses while we wait for inspector availability.

Your water may be temporarily shut off

When our plumber is doing the below-ground rough-in, they may need to shut off your water supply for a few hours. We’ll notify you as far in advance as possible, but please text us if the timing causes any issues and we’ll work around your schedule.

Concrete trucks will visit the site

On pour day, you’ll see concrete trucks arrive. This can be loud and may temporarily affect street parking or driveway access. We’ll give you a heads-up on the scheduled pour date so you can plan accordingly.

The foundation needs time to cure

After the pour, the concrete needs time to set and cure properly. You’ll see the forms stay in place for a bit before they’re stripped. Please keep people and pets away from the fresh concrete—it looks solid before it’s fully cured.

Drainage work may follow the pour

A French drain and drywell may be installed after the foundation is poured. This involves additional trenching near the foundation, so expect a bit more ground disturbance before we move on to framing.

Sewer work may cause a temporary odor

Below-ground sewer rough-in involves opening sewer lines, which can occasionally produce odors. This is temporary and typically resolves once connections are sealed and inspected.

This phase typically takes about 4 weeks

The foundation is methodical by design. Weather and inspector availability can shift the timeline slightly. We’ll keep you informed of any changes.

An invoice will be sent at the end of this phase

Once the foundation is complete, we’ll send Invoice 03 per your payment schedule.

Milestone 5:
Framing

Overview

Now the fun part—your ADU starts to take shape! Framing is when walls go up, the roof structure is built, and sheathing goes on. You’ll finally be able to walk through the space and see the layout come to life. This phase also includes multiple inspections, installation of pocket door frames and blocking, and a detailed internal review to make sure everything is perfectly aligned before the next trades come in.

What to Expect

Your ADU will visually take shape

This is one of the most exciting milestones because you’ll see your project go from a flat slab to a three-dimensional structure. Feel free to visit (safely!) and take photos—just let us know when you plan to stop by.

There will be significant material deliveries

Lumber, sheathing, and other framing materials will be delivered. This can temporarily take up driveway or yard space. If access is a concern, text us and we’ll coordinate delivery timing.

Expect sawing, hammering, and nail guns

Framing is one of the noisier phases. Crews will be cutting lumber and using nail guns throughout the work day. If you have meetings or events at home, let us know in advance and we’ll see what we can do.

City and structural engineer inspections will occur

The structural engineer will do a framing special inspection, and the city will inspect shear, roof nailing, and the frame. These are standard checkpoints that ensure structural integrity.

We’ll verify cabinetry and layout details

Before rough-in begins, we’ll take precise measurements of all framing openings and verify the cabinetry layout. If we have questions about your selections or layout preferences, we’ll reach out to confirm.

Roofing materials will be ordered

Once the roof structure is sheathed, we order roofing materials including gutters, downspouts, and gutter guards. You may see additional deliveries arrive.

This phase typically takes about 3 weeks

Framing moves quickly once it starts, but inspections and weather can introduce short pauses. We’ll keep you updated on progress.

An invoice will be sent at the end of this phase

Once framing is complete and inspected, we’ll send Invoice 04.

Milestone 6:
Sheetrock

Overview

This is the longest and most activity-packed milestone. It covers everything from the roof going on, to all the mechanical rough-ins (electrical, plumbing, HVAC), to windows and doors being installed, and finally the sheetrock going up and getting finished. Multiple city inspections happen during this phase. By the end, your ADU will have sealed walls, a finished roof, and be ready for the finishing touches.

What to Expect

Many different trades will be on-site

Roofers, electricians, plumbers, HVAC technicians, window installers, and sheetrock crews will all cycle through during this milestone. You’ll see a lot of different faces and vehicles. This is normal and means progress is happening on multiple fronts.

Your water or power may be briefly interrupted

The above-ground plumbing and electrical rough-ins may require brief service interruptions to your main house. We’ll always try to give you advance notice. If any interruption is causing a problem, text us right away.

The exterior will come together

Roofing, house wrap, windows, doors, and flashing will all be installed. Your ADU will start looking like a finished building from the outside. Siding is typically installed during or shortly after this phase.

Multiple city inspections are required

The city will inspect the rough mechanical work (electrical, plumbing, HVAC), exterior waterproofing, and sheetrock screws. Each inspection must pass before we can proceed to the next step. Occasionally, an inspector may require a minor correction, which is routine.

Sheetrock dust is unavoidable

Hanging and finishing sheetrock generates fine dust. We take precautions to contain it, but some dust may drift beyond the construction area. If it’s affecting your main home, let us know and we’ll take additional measures.

Taping and topping takes time

After the sheetrock is hung, the taping, mudding, and finishing process takes about 10 working days. Each coat needs to dry before the next can be applied. The space will look rough during this process, but the end result is smooth, paint-ready walls.

We’ll finalize landscaping and hardscaping plans with you

During this phase, we’ll sit down with you to finalize any landscaping, hardscaping, deck, or fencing plans so everything is ordered and scheduled in time for the final phases.

We’ll notify you about window and door lien requirements

Per state regulations, you’ll receive a notification about material liens related to your windows and doors. This is standard procedure and protects both you and the suppliers.

This phase typically takes about 6 weeks

This is the longest milestone because so much happens. Weather, inspector availability, and material lead times can all affect the timeline. We’ll provide regular updates.

An invoice will be sent at the end of this phase

Once sheetrock is complete, we’ll send Invoice 05.

Milestone 7:
Millwork & Trim

Overview

This is where your ADU transforms from a construction site into a home. Paint goes on the walls, flooring is installed, cabinets and countertops go in, and all the trim, baseboards, and millwork give the space its finished character. Plumbing and electrical get their final fixtures, appliances are installed, and the HVAC system is commissioned. It’s the phase where all the details come together.

What to Expect

The space will start looking move-in ready

This is the most visually rewarding phase. Each day brings noticeable progress as paint, flooring, cabinets, countertops, and fixtures transform the space. We love sharing progress photos during this time!

Paint fumes may be noticeable

Interior and exterior painting happens early in this phase. While we use standard-grade paints, some odor is unavoidable. Keep windows in your main home closed if it bothers you, and let us know if you have any sensitivities.

Flooring installation requires a controlled environment

Flooring materials often need to acclimate to the space before installation. You may notice materials sitting in the unit for a day or two before the installers arrive—this is intentional and ensures a quality result.

Cabinetry and countertops are installed in sequence

Cabinets go in first, followed by countertops. There’s typically a gap between the two while countertops are fabricated to fit. This is normal and not a delay.

Final plumbing and electrical fixtures go in

Sinks, faucets, toilets, light fixtures, outlets, and switches are all installed during this phase. If you have any last-minute questions about placements, now is the time to ask.

HVAC will be tested and commissioned

Your heating and cooling system will be turned on and tested. We’ll verify it’s working correctly before moving to the final phase.

We’ll do a thorough internal punchlist

Our team conducts a detailed post-sheetrock punchlist to catch any imperfections—paint touch-ups, trim adjustments, hardware alignment, etc. This review takes about a week and ensures everything meets our standards before your walkthrough.

This phase typically takes about 6 weeks

There are many sequential tasks that can’t overlap, so this phase takes a while even though the work moves steadily. We’ll keep you updated on progress.

An invoice will be sent at the end of this phase

Once all millwork and trim is complete, we’ll send Invoice 06.
