Taking ownership of your new construction home and moving in can feel like the finish line. As relieving as that milestone may be, it is not a time to stop thinking about the home.

Closing day comes with a set of deadlines, financial adjustments, and maintenance windows that no builder sales office bothers to explain. The buyers who miss them often pay for it in ways that feel completely avoidable in hindsight.

If you are buying in Clark County, here is what you need to know before those windows close.

Property Taxes Can Jump in Year Two

When you close on a new construction home, the property tax assessment often reflects only the land value. The completed structure has yet to enter the equation. That changes fast, and the gap between what your lender estimated and what Clark County actually bills can be jarring.

Under Washington State's property assessment process, governed by the Washington State Department of Revenue, the county reassesses once construction is complete. Your year-two tax bill can land significantly higher than what your lender modeled at closing.

If your escrow account covers only the original land-only assessment, the payment adjustment will feel like it came from nowhere. However, there is a way to prepare. Before you close, ask your lender to walk you through what year-two taxes will likely look like once the home is fully assessed. Get a realistic number and build it into your monthly budget now.

A property tax adjustment of $150 to $400 per month is not unusual in Clark County's newer communities. That is a number worth planning for in month one rather than absorbing in month thirteen.

You can also explore Washington's available exemptions early. Qualifying senior buyers should look at the Clark County Assessor's senior property tax relief programs. Getting that paperwork filed right after closing puts the savings to work immediately.

Issues That Can Void the Builder Warranty

Builder warranties can seem simple at a glance. They outline time periods under which certain issues are covered. However, the terms are complex, and buyers can void parts of coverage in ways they might not expect.

Most buyers know the house has warranty coverage, but few actually understand their role in maintaining coverage. That's where having representation for a new construction purchase can make a difference.

"If you go and put on a covered patio and it was not done by the builder, it could negate your siding warranty. If you put arborvitae in for some privacy, that could negate the drainage warranty because you might change the grade of the backyard. You need to know what the warranty verbiage means. And you need to know whether what you're planning could negate it." – Erin Smiley, New Construction Specialist, New Construction Market Experts

The 2-10 Home Buyers Warranty program, common across Clark County builders, has shifted its structure in recent years. The first year offers craftsmanship coverage. Systems coverage beyond that no longer follows the clean timelines it once did. The protection is likely still there, but you need to understand what you have before you start modifying the home.

What Should Be on Your Year-One Ownership Calendar?

Year one in the new home is a time to stay engaged and manage your coverage. Knowing what you should and shouldn't do can protect your coverage and the investment in the home.

"Put in your calendar these time frames so you don't forget. Go to Amazon, subscribe, and have a lovely air filter delivered to your front door every three months so you don't have to think about it. You can have a home inspection at that year mark, just to make sure everything looks good. And if something comes up, send in an email through the warranty portal. If you've had a problem at six months and you wait until month fourteen, you're no longer covered. That's going to be an uphill battle." – Erin Smiley, New Construction Specialist, New Construction Market Experts

Here is the basic calendar that protects most buyers:

• Month One: Your superintendent is likely still on site, so it's a great window to take advantage of. Small items get resolved with zero friction at this stage.
• Every Three Months: Replace HVAC filters regularly and check the crawl space, especially after heavy rain. If a room runs consistently hot or cold, call your warranty department and request an HVAC technician to rebalance the system. That is a covered service. Do not let the window close before you use it.
• Month Eleven or Twelve: Schedule a third-party home inspection before your craftsmanship warranty expires. This is your last low-friction opportunity to document anything that needs attention under covered terms. Book it in advance since inspectors fill up fast; it's a smart move to secure your spot early.

Many Clark County builders now send quarterly newsletters with seasonal maintenance reminders. In the Pacific Northwest, that includes checking drainage grades after fall rains and blowing out irrigation systems before a freeze. Taking them seriously can help turn what might become a $4,000 repair into a simple $200 service call.

Is a New Construction Home Actually Low Maintenance?

New construction buyers sometimes arrive at closing feeling they have purchased something close to maintenance-free. The home is brand new, everything works beautifully, and there's a warranty in place. While that is mostly true, being proactive during that first year matters.

• Nail pops are normal; framing adjusts as seasonal moisture changes, and the structure settles over the first twelve to eighteen months.
• A loft that runs warm in summer can often be corrected by a covered HVAC rebalancing, if you report it during the warranty window.
• Settling cracks in drywall are expected and covered under craftsmanship terms.

None of these issues mean there is anything wrong with the home. It's all just part of that first year of settling. Many of them can also be addressed under the warranty if you pay attention and take the time to report them.

FAQs About the First Year in a New Construction Home

Why did my property tax bill jump significantly in year two?

At closing, your property tax assessment typically reflects only the land value, not the completed structure. Once Clark County reassesses the finished home, the taxable value increases substantially. This reassessment usually hits in year two and can produce a bill that is noticeably higher than what your lender estimated at closing. Planning for this adjustment before closing is far easier than absorbing it after.

What specific improvements most commonly void a builder warranty?

Landscaping that alters the drainage grade near the foundation is one of the most common triggers to watch for. Patios or covered structures installed by non-builder contractors, along with roofline or exterior cladding modifications, are also worth keeping in mind. Fence installations that disturb grading and irrigation systems added after closing can also create issues. The rule is simple: contact your warranty department before any exterior modification, regardless of how minor it seems.

How does the 2-10 Home Buyers Warranty structure work?

The program offers warranty protection, typically divided into three tiers. It includes one year of craftsmanship coverage, two years of systems coverage for plumbing and electrical, and ten years of structural coverage. Builders issue their own addendums on top of the base program, and those terms have been shifting. Your actual warranty documents govern, not the general program description.

How much does a third-party home inspection cost at the one-year mark?

Inspection costs in Clark County typically range from $300 to $500 for a standard single-family home. Actual costs depend on square footage and the inspector's scope. A documented inspection in month eleven gives you a timestamped record before your craftsmanship warranty closes, and a qualified inspector will find things you missed.

What should I do if a builder denies a warranty claim I believe is valid?

Pull the warranty documents to identify the specific coverage language the builder is relying on to explain their decision. Submit a formal written response through the warranty portal, citing the relevant section. If the denial stands and the issue is significant, there's a clear path forward. Washington's construction defect statute, RCW 64.50, establishes a notice-and-cure process before litigation becomes necessary. Consult a qualified attorney for guidance on your specific situation. For a deeper look, read our post about the value of researching builder warranty reputation.

If my builder sends a warranty addendum mid-construction, am I required to accept it?

This is a contract and legal question that depends on your specific purchase agreement and Washington State law. Do not accept or sign any addendum without first understanding how it changes your existing coverage. Consult a qualified attorney before signing anything that modifies your warranty terms. A buyer's agent who specializes in new construction can be a real asset. They can often flag these situations early, well before they turn into a real problem.

Does submitting a warranty claim affect my relationship with the builder or my ability to resell?

No. Submitting warranty claims does not create a negative record that follows the home or affects your ability to sell. In fact, documented repairs with timestamps can demonstrate to future buyers that issues were properly addressed and resolved during the warranty period.
