— Our Process
How Ironside Building Manages Your Project from Start to Finish
Construction project management is where projects succeed or fail. Our structured process gives you full transparency at every phase — no surprises, no gaps in accountability, no budget ambiguity.
Step 1 — Site Evaluation & Project Scoping
We begin with a thorough site assessment and consultation to understand your goals, constraints, and budget. For commercial projects this includes zoning review and landlord coordination. For residential, we assess lot conditions, setbacks, and utility access. This phase produces a clear project scope before any dollars are committed to design.
Step 2 — Design & Pre-Construction Planning
Our design-build model integrates architecture and construction from day one. We develop detailed construction drawings, coordinate with structural and MEP engineers, and build out your bid package with itemized line items. You review and approve before we touch a permit application.
Step 3 — Permitting & Municipal Coordination
We navigate the permitting requirements for your specific Orange County municipality — whether that’s the City of Irvine’s plan check process, coastal development permits in Laguna Beach, or health department approvals for restaurant build-outs. Our team manages all submittals, plan check responses, and inspection scheduling so nothing falls through the cracks.
Step 4 — Subcontractor Coordination & Construction
We work with a vetted network of licensed subcontractors across all trades — framing, plumbing, electrical, HVAC, concrete, drywall, and finish work. Our superintendents manage daily site operations, enforce quality standards at each milestone, and coordinate inspections with your city’s building department.
Step 5 — Final Inspections, Punch List & Handover
We conduct a thorough pre-final walkthrough before inviting city inspectors, addressing any outstanding items ahead of your Certificate of Occupancy inspection. You receive a complete close-out package including warranty documentation, as-built drawings, and final lien releases from all subcontractors.

— Frequently Asked Questions
Common Questions About General Contractor Services
Q: What does a general contractor do in Orange County?
A general contractor manages the full scope of a construction project — hiring and scheduling subcontractors, procuring materials, pulling permits, coordinating inspections, and ensuring the project is completed on time and within budget. In Orange County specifically, a GC also navigates the unique permitting requirements across 34 different municipalities, coastal zone regulations, and California energy compliance standards like Title 24.
Q: Do I need a licensed general contractor in California?
Yes. California law requires that any contractor performing work valued over $500 must be licensed by the Contractors State License Board (CSLB). Hiring an unlicensed contractor exposes you to significant legal and financial risk — including liability for injuries on your property. Ironside Building carries a Class B General Building Contractor license, a $25,000 contractor’s bond, and full General Liability and Workers’ Compensation insurance.
Q: How long does a custom home take to build?
A custom home typically takes 12–18+ months from permit issuance, depending on size and complexity. Pre-construction — design, engineering, and plan check — can add another 3–6 months before construction begins. Our design-build process streamlines this timeline by keeping architecture and construction under one roof, reducing the back-and-forth that delays traditional project delivery.
Q: How much does a high-end home remodel cost in Orange County?
Whole-home renovations in premium coastal areas like Newport Beach typically run $200–$280 per square foot for comprehensive interior and exterior scope. Luxury kitchens, primary suite remodels, and projects involving structural modifications will sit at the higher end of that range. Ironside Building provides detailed, itemized bids so you know exactly where every dollar is going before work begins.
Q: How much does a commercial tenant improvement cost in Orange County?
Tenant improvement allowances in Southern California currently range from $30–$45 per square foot for Class A inline retail, and $50–$65 per square foot for restaurant uses in premium centers. Total project cost depends on existing conditions, finish level, and scope. We provide fully itemized bids before any work begins so there are no surprises at the end.
Q: Can Ironside Building help with ADU construction?
Yes. We build Accessory Dwelling Units across Orange County, navigating the evolving ADU regulations supported by legislation including AB 68, SB 9, and AB 1033. ADU projects typically cost $60,000–$350,000 and take 6–14 months from design through Certificate of Occupancy. We manage design, permitting, and construction as a single integrated process.
Q: Does Ironside Building handle production housing and multifamily development?
Yes. We support developers and production builders with high-volume residential construction across Orange County. This includes tract housing, planned communities, townhome developments, apartment projects, and mixed-use builds. Our systemized construction processes manage concurrent trade scheduling across multiple units — delivering consistency and speed without sacrificing quality.
