What We Build

Ground-Up Construction, Managed Start to Finish

New home construction involves more moving parts than a remodel — design, engineering, permitting, and a much longer build. One licensed contractor manages all of it.

Custom Home Builds

A full custom home built from the ground up on your lot — designed around how you actually want to live, not a production floor plan.

Teardown & Rebuild

Demolish an outdated or damaged home and build new in its place — often the better move than renovating a structure that's fighting you at every turn.

Spec Homes

Built on speculation to sell — designed with broad market appeal, quality finishes, and a build process managed to protect your margin from surprise cost overruns.

Accessory Dwelling Units

Detached ADUs, garage conversions, attached ADUs, and JADUs — a faster, lower-cost path to real square footage under California's streamlined ADU laws. See our full ADU services.

Design & Permitting

Architectural plans, structural engineering, and submission through your city's plan check process — plus HOA architectural review where applicable — managed for you.

Site Prep & Utility Connections

Grading, excavation, and new or upgraded electrical, water, and sewer connections — coordinated so every system is in place before framing starts.

Why ProHome

A builder that manages the whole process

New construction fails most often when the design team, the permitting process, and the construction crew aren't coordinated — plans that don't match what the city will approve, or a builder who inherits someone else's design mistakes. We manage it as one process, start to finish.

Regular Updates, Without Asking

A build that takes a year or more only works if you're not left guessing. You'll hear from us throughout — what happened, what's next, and any changes.

One Team, Design Through Final Inspection

Architecture, engineering, permitting, and construction managed under one roof — no gap where the designer's plans don't match what actually gets built.

No Surprise Costs

A detailed, itemized scope before ground breaks. Change orders are presented before work starts — not as a line item you discover on the final invoice.

Common Questions

Home Builder FAQ

Straight answers to the questions we hear most often from Orange County homeowners.

What kind of home building projects do you take on?
We build custom single-family homes from the ground up, handle teardown-and-rebuild projects on existing lots, build spec homes, and construct accessory dwelling units (ADUs) — detached, attached, garage conversions, and JADUs. As a licensed B-General contractor (CSLB #1140564), we manage design coordination, permitting, and construction under one roof.
How long does it take to build a custom home in Orange County?
Design and permitting typically take 4 to 9 months depending on your city's plan check timeline and project complexity. Construction on a custom single-family home generally runs 10 to 18 months once permits are issued. Teardown-rebuild projects add demolition time upfront. We give you a realistic project timeline before you sign anything.
Do you handle the architecture and permitting, or just construction?
We coordinate the full process — architectural plans, structural engineering, and submission through your city's plan check, along with HOA architectural review where applicable — then build once permits are issued. You have one point of contact from first sketch to final inspection instead of managing a designer and a separate builder yourself.
What does it cost to build a new home in Orange County?
Ground-up construction in Orange County typically runs $350 to $600+ per square foot depending on finish level, lot conditions, and site work, with teardown-rebuilds adding demolition and utility costs. An ADU is a more contained project, generally $150,000 to $400,000 depending on size and finishes. We give you an itemized estimate after a site visit — not a rough per-square-foot number pulled from a national average.
Can I build an ADU instead of a full new home?
For many Orange County homeowners, yes — an ADU adds real living space, rental income potential, or room for family, often for a fraction of the cost and timeline of a full custom build. California's streamlined ADU laws have made the permitting process faster than a standard addition. See our dedicated ADU contractor pages for detached ADUs, garage conversions, attached ADUs, and JADUs.
