Frequently Asked Questions
New Construction Process
How long does new construction take?
Plan on 10-14 months from groundbreaking to completion for most new homes. Larger homes, complex sites, or extensive custom features extend timelines. Weather affects foundation and framing schedules significantly. We provide realistic timelines based on your specific project and keep you updated as construction progresses.
What's the first step in new construction?
We start by understanding your vision, budget, and timeline. Then we assess your site for building feasibility, soil conditions, access, and utilities. From there, we develop or coordinate design plans and provide detailed cost estimates. Once plans and budget are approved, we handle permits and begin construction.
Do you handle all permits and inspections?
Yes, we manage all permitting, building department coordination, and inspection scheduling. We know what Sonoma and Marin County building departments require and submit complete applications. We schedule required inspections at the right times and address any inspector comments immediately.
Can we make changes during construction?
Changes can be made, but early changes are much easier and less expensive than changes after framing or systems are installed. We document all change orders with cost and timeline impacts clearly spelled out. You’ll understand exactly what changes mean before we proceed with the work.
Design & Planning
What's included in design-build services?
Design-build includes initial design consultation, floor plan development, exterior and interior design, material selections, construction drawings, permit processing, and complete construction. You work with one team throughout instead of coordinating separate designer and builder. This streamlines communication and accountability.
How detailed are the construction plans?
Construction plans include floor plans, elevations, foundation details, framing plans, electrical and plumbing layouts, and specifications for materials and finishes. Plans need enough detail for permitting, accurate estimating, and guiding construction. We ensure plans are complete before construction starts.
Can we see 3D models before construction?
Yes, 3D modeling is part of our design process. We create models showing exterior appearance and interior spaces so you can visualize the finished home. This helps with design decisions and material selections. Changes in 3D cost nothing compared to changes during construction.
Do you work with our interior designer?
Yes, we coordinate with interior designers regularly. Designers help with finish selections, color schemes, fixture choices, and decorative details. We integrate their selections into construction and coordinate timing for custom elements. Good collaboration produces better finished homes.
Site & Foundation
What site conditions affect new construction?
Soil conditions, slope, drainage, access, and utility connections all affect construction. Rocky soil or poor bearing capacity require different foundation approaches. Steep slopes need retaining walls and engineered solutions. Limited access affects equipment use and material delivery. We assess these factors during planning.
How do you handle challenging building sites?
Challenging sites require proper engineering and planning. We bring in soil engineers for testing, design appropriate foundation systems, plan drainage solutions, and coordinate equipment access. Difficult sites cost more and take longer, but we assess them realistically and plan accordingly.
What foundation types do you use?
Foundation type depends on soil conditions, slope, and home design. We use slab-on-grade for flat sites with good soil, crawl space foundations for moderate slopes or poor drainage, and engineered systems for hillsides or challenging conditions. We design foundations to match site conditions and building loads.
Do you handle site utilities?
Yes, we coordinate all utility connections—water, sewer or septic, electric, gas, and internet. We work with utility companies on service installations, handle trenching and connections, and ensure everything is tested and operational before final inspection.
Budget & Timeline
What affects new construction costs?
Size, finish quality, site conditions, and design complexity affect costs most. Custom features, high-end materials, and challenging sites increase expenses. Efficient floor plans and material choices help control costs without sacrificing quality. We provide detailed estimates showing where money goes.
Are there costs beyond the construction contract?
The construction contract covers building the home, but you’ll also have costs for land purchase, financing fees, design fees if using an architect separately, furniture, and initial landscaping beyond basic grading. We help you understand total project costs up front.
How do we pay for new construction?
Most clients use construction loans that disburse in phases as work progresses. We work with your lender on draw schedules, provide required documentation, and coordinate inspections for fund releases. Final payment typically happens at completion when you secure permanent financing.
What if costs exceed the budget during construction?
We provide detailed estimates and work to hit those numbers. If unexpected conditions arise—like poor soil or hidden site issues—we communicate immediately with cost implications before proceeding. Our goal is preventing surprises through proper planning and clear communication.
Quality & Completion
How do you ensure construction quality?
Quality control happens at every phase. We use skilled tradespeople, source quality materials, inspect work before covering it up, and don’t move forward until work is done correctly. Our reputation depends on quality, so we don’t cut corners or rush work.
What warranty comes with new construction?
We provide comprehensive workmanship warranties, and manufacturers warrant appliances, systems, and materials. We address any issues promptly during the warranty period. We stand behind our work and remain available after you move in.
What happens at final walkthrough?
At final walkthrough, we inspect everything together to ensure it meets your expectations. We address any punch list items, demonstrate how systems work, provide warranty information and manuals, and answer questions. We don’t consider the project complete until you’re satisfied.
