Thinking about buying a new-construction home on the Eastside but not sure how to size up the builder? You are not alone. With strong demand in Bellevue and the Seattle-Bellevue-Everett corridor, you will see a wide range of builders, timelines, and contract structures. This guide shows you how to vet a builder with confidence, what to look for in contracts and construction quality, and which local checks matter most so you can protect your investment. Let’s dive in.
Why due diligence matters on the Eastside
New construction in Bellevue and greater King County follows Washington State building codes with local amendments. That means your builder must navigate permits, inspections, and Certificates of Occupancy before closing. When you confirm that process is on track and documented, you lower risk.
Local market dynamics also matter. Material costs, labor constraints, and supply-chain delays can extend timelines. Eastside demand has stayed strong, which influences pricing, upgrade availability, and how competitive you must be when selecting lots or homes. Solid due diligence helps you compare builders on more than just finishes and photos.
Verify licensing, insurance, and complaints
Start with the basics. Washington requires contractor registration and compliance with state rules. Ask the builder for proof of registration, general liability insurance, and workers’ compensation coverage. Confirm specialty licenses for key trades when required.
Check for any active discipline or enforcement actions with Washington state regulators. Review consumer complaint channels, including the Washington State Attorney General and business-rating platforms. Read online reviews with care. Look for patterns and corroborate serious claims using public records.
Use permit and inspection records
Bellevue and King County provide public permit lookup tools. Search the specific lot or project to review permit status, inspection outcomes, and any corrections. You can often see if there were stop-work orders, repeated failed inspections, or code-enforcement actions.
Ask the builder for recent addresses and walk through completed homes. When possible, visit an active job site to observe safety, cleanliness, and workmanship. If you speak with current owners, focus on warranty responsiveness, schedule accuracy, and how well the finished home matched the contract.
Evaluate portfolio, trades, and approach
A builder’s track record should align with the product you want. If you are considering a modern luxury home in West Bellevue, review similar finishes, square footage, and architectural styles in the builder’s portfolio. Consistency across homes is a strong indicator of process discipline.
Ask who performs the critical work. Some builders self-perform foundation or framing. Others rely entirely on subcontractors. Transparency about regular trades, how they are vetted, and how quality is verified tells you a lot about accountability.
Longevity and local presence matter. An established Eastside builder often has deeper relationships with inspectors, plan reviewers, and trade partners, which can smooth communication and scheduling.
Know what belongs in the contract
Protect yourself with a clear, itemized contract. Look for:
- Scope and inclusions: Detailed lists of what is included versus upgrades.
- Allowances: Dollar amounts for finishes like flooring, lighting, and appliances, plus the process to select and price options.
- Timeline: Start and completion targets, reasons for extensions, and how delays are handled.
- Change orders: How pricing works, who approves, and how schedule changes are documented.
- Financing contingencies: Whether your contract depends on mortgage approval or a specific lender.
- Deposits and escrow: Amounts, refundability, and how funds are protected.
- Remedies: Whether there are liquidated damages for late completion or remedies for buyer-caused delays.
- Dispute resolution: Arbitration or mediation rules, and small-claims options.
- Termination and default: What happens if either side ends the agreement.
- Assignment and resale limits: Especially relevant in new subdivisions or townhome communities.
Consider having a real-estate attorney or an experienced agent review the agreement before you sign. Precise language reduces surprises later.
Understand total cost beyond the base price
Budget for more than the sticker price. On the Eastside, you may see:
- Lot premiums for preferred locations or views.
- Local impact and permit fees that vary by jurisdiction.
- Utility connection fees and site work expenses.
- Landscaping allowances and hardscape extras.
- Upgrades and custom changes to finishes or systems.
- Sales tax on materials and certain services.
Ask for a line-item estimate and a realistic range for upgrades based on your preferences. Knowing the full picture early helps you manage cash flow and expectations.
Plan your financing and incentives
Depending on the build, you may use a construction-to-permanent loan or close with a standard mortgage after the Certificate of Occupancy. If you need a longer build timeline, plan how you will handle rate locks and any extension fees.
Many builders offer incentives like rate buydowns or closing-cost credits. Compare the net value against alternative lenders and confirm any conditions. If you are using FHA or VA financing, verify that the home and builder meet program requirements before you commit.
Schedule inspections at key milestones
Municipal inspections check code compliance, but you should also invest in independent inspections. Recommended milestones include:
- Pre-pour or foundation stage to confirm footings, reinforcement, and waterproofing details.
- Rough-in after framing with plumbing, electrical, and HVAC installed but before insulation and drywall.
- Insulation and air-sealing checks to verify energy-code compliance.
- Final inspection and a thorough third-party home inspection before closing to build a punch list.
- An 11 to 12-month warranty walkthrough to catch any issues before the 1-year workmanship coverage ends.
Your inspector should review drainage, grading, and mechanical ventilation, along with typical finish items. Document everything in writing.
Check energy performance and testing
Washington’s energy code has tightened in recent years, and Bellevue may add local requirements. Ask the builder how the home complies with the Washington State Energy Code and whether the project targets voluntary certifications like ENERGY STAR, HERS ratings, or Built Green.
If a builder advertises performance claims, request the third-party testing reports. Blower door and duct leakage tests provide objective data you can use to estimate long-term energy costs.
Understand warranties and post-closing service
Most builders follow a common warranty structure: about 1 year for workmanship items, 2 years for major systems like electrical, plumbing, and HVAC, and up to 10 years of limited structural coverage. Terms vary, so get the full warranty in writing.
Clarify when coverage starts, what is excluded as normal wear, and whether the warranty transfers to a future owner. Ask for details on how to submit claims, typical response times, and whether a third-party warranty company manages the process. Request examples of warranty issues handled in the past 2 to 3 years.
Protect yourself at closing with lien waivers from subcontractors and suppliers. If necessary, negotiate a small holdback in escrow tied to final punch-list completion or permit sign-offs.
Local Eastside considerations
The Eastside includes infill single-family homes, townhomes, planned communities, and high-end custom builds. A builder experienced in your specific product type is a plus.
Many subdivisions use HOA covenants and design review. Review CC&Rs early so you understand exterior standards, landscaping rules, and any design controls.
Site conditions vary across Bellevue and King County. Confirm setbacks and easements. Understand tree protection requirements and any mitigation obligations. Review drainage and stormwater plans and clarify long-term maintenance for shared facilities. On sloped lots, ask for the geotechnical report and confirm retaining wall warranties.
Neighborhood amenities, transit access, and school boundaries can influence resale value. Check the King County Assessor for current tax details and whether special assessments apply to your development.
A practical checklist you can use
Before you sign:
- Verify contractor registration, insurance, and any regulatory actions.
- Walk completed homes and one active job site.
- Review sample contracts plus specific scope and allowance documents.
- Confirm financing contingencies and deposit refund rules.
- Obtain full warranty terms and examples of recent claims.
- Preview permit history for your lot or project.
During construction:
- Attend milestone inspections and hire an independent inspector at key phases.
- Keep all change orders in writing with itemized pricing and schedule impacts.
- Track permits, inspection results, and corrections.
- Photograph progress at key stages for your records.
Pre-closing and after:
- Complete a detailed final walk-through and punch list.
- Confirm municipal final approvals and Certificate of Occupancy.
- Collect lien waivers and final insurance confirmations.
- Calendar your 11 to 12-month warranty check.
Red flags to avoid
- No active registration or evidence of enforcement actions.
- Refusal to allow independent inspections or limited site access without cause.
- Vague language about allowances, change orders, or completion dates.
- Large, nonrefundable deposits without escrow protections.
- No references or unwillingness to share addresses of recent homes.
- Heavy subcontracting with little transparency about who does critical work.
- Poor online reputation supported by documented permit or inspection issues.
