I'm Brian Cooper. Building a custom home in Simi Valley — from raw parcel to closing — is a rewarding but complex journey. Here's the process step by step so you know what to expect.
Step 1: Land and feasibility
Acquire a buildable lot, then verify zoning, utilities, soils, and any geotechnical or grading needs before you commit to a design.
Step 2: Design and budget
Engage an architect, develop plans, and build a realistic budget with contingency for overruns. Choose your builder and lock a contract with a clear scope, allowances, and change-order process.
Step 3: Permitting
Submit to the City of Simi Valley / Ventura County for plan check and permits. This can take months and may require revisions.
Step 4: Construction and financing
A construction loan typically funds in draws as work completes, converting to a permanent mortgage at the end. Stay on top of draws, allowances, and change orders.
Step 5: Inspections and completion
Inspect at key stages (foundation, framing/pre-drywall, final), complete a punch list, pass the final municipal inspection, and obtain a certificate of occupancy before closing the permanent loan.
Bring your own agent — it doesn't cost you more
The friendly sales associate at the a custom build model home works for the builder. They're paid to protect the builder's interests and maximize the builder's price and margin. You deserve someone on your side.
In California, having your own buyer's agent at a new-construction community generally does not raise your price — builder marketing budgets anticipate buyer-agent participation. The one rule: I usually need to register with you on your first visit. If you tour and give your information before I'm named, some builders will not honor representation later.
Questions to ask the builder before you sign
- What's included as standard versus an upgrade on this floor plan?
- What incentives apply right now, and are they tied to your preferred lender?
- What is the exact Mello-Roos/CFD amount and HOA due on this specific lot?
- What's the realistic completion date, and what happens if it slips?
- What does the warranty cover, and for how long (workmanship, systems, structural)?
- Can I use my own lender and my own inspector?
- Which lots carry premiums, and why?
