What we build (6)

Ground-up residential, end-to-end.

Show us your vision. We'll tell you what it'll cost to build.

01 Site prep + grading

Clearing, rough grade, pad cut, drainage. We start from a survey and finish with a pad ready for foundation.

Grading & compaction
Erosion control
Underground utilities

02 Foundation + structural

Footings, slab or stem-wall, framing — engineered to your soils report and the load you're carrying overhead.

Engineering coordination
Slab or stem-wall
Framing inspection

03 Vertical construction

Walls, roof, sheathing, weather barrier — the dry-in moment is when the project pivots from contingency to certainty.

Framing & sheathing
Roofing
Weather-tight envelope

04 Mechanical, electrical, plumbing

mechanical, electrical, and plumbing rough-in routed to fit your finish plan, not the other way around. Trim sizes and wall depths get the design they earn.

05 Interior finishes

Cabinetry, stone, tile, paint. Every selection log gets a written allowance against it; surprises are how trust dies.

From vision to keys

Phase 01 · Survey
Walk the lot first.
Soils, slope, setbacks, neighbor friction. We flag what's hard before drawings start, not during permitting.
Phase 02 · Engineering
Drawings built to clear plan check.
Architect coordination, structural engineering, and soils when the lot calls for it — prepared to keep city-comment cycles short.
Phase 03 · Permits
We handle city submittal.
We take care of the submission, comments, and resubmittal to the city. You sign once; we carry it all.
Phase 04 · Construction kickoff
Construction officially begins.
We prepare the site, confirm the plan, and begin the first phase of work.
Phase 05 · Inspection
Inspector Ready, Project Steady.
We schedule the required inspections, meet with the city inspector, and address any corrections needed to keep the project moving.
Phase 06 · Project Completion
Finished, Polished, Delivered.
Final work is wrapped up, the site is cleaned, and we walk through the finished project with you.

Process

From survey to certificate of occupancy.

One conceptual floor plan, developed through every phase. Schematic, not an engineering detail.

Free consultation

We meet you on the lot. Soils, slope, setbacks, neighbor friction — flagged before drawings start, not discovered during permitting.

01 / Time and budget

How long does ground-up actually take in Orange County?

Plan on twelve-to-eighteen+ months from permit submittal to certificate of occupancy on a single-family build, longer for a complex site. The variance is permitting, not construction — we tell you on day one which side of that range your vision lives on.

Will the bid hold through a long schedule?

We carry escalation as a written allowance. Material movements get tracked monthly; if a category is going to land outside the allowance, you hear it before the trade starts, not at billing.

02 / Working with Avorino

What if I haven't picked an architect?

We can work with your architect, or we can handle the project through our design-build process. Either way, design and construction stay aligned from day one, so decisions are guided by real budget, schedule, and buildability.

Can you handle the engineering, soils, and survey work?

We coordinate the engineer of record, soils engineer, and surveyor. You see one project schedule and one point of accountability.

What's your role after move-in?

Final walkthrough plus the tiered warranty — 1-year fit & finish, 4-year systems, 10-year structural — with the same Avorino team on the phone. Most ground-up clients call us once or twice in the first year, then we talk again when they're ready for the next project.
