Happy Valley's Growth Is Fast. Your Inspector Should Know New Construction Cold.

Happy Valley is Oregon's fastest-growing city, and most of its homes are less than 20 years old. New construction and recently annexed neighborhoods like Pleasant Valley and North Carver each carry their own inspection risks. As a Certified Master Inspector® with 10+ years of inspection experience and hands-on work as a licensed general contractor, Russ knows what builders miss.

Happy Valley Know-How

These Homes Have History. So Do I.

A Happy Valley Oregon home representative of the Clackamas County housing stock Russ inspects
Happy Valley, Oregon

Happy Valley is unlike almost any other city in the Portland metro. Most of its homes didn't exist 25 years ago. Jackson Hills, Pleasant Valley, and North Carver are still being built out. The original core neighborhoods from the early 2000s are now old enough to have real maintenance issues. And radon still needs a test, even in a county the EPA rates as Zone 3. That combination creates an inspection profile you don't see anywhere else in the region.

I've been inspecting homes for 10 years, and I'm a licensed general contractor. High-end and difficult framing is my specialty. I've also replaced roofs, built and installed cabinets, run wiring, poured concrete, waterproofed showers, set tile, hung drywall, and swapped out siding and windows. A brand new house doesn't intimidate me because of it. I already know where the crew was in a hurry.

When I walk a new build in Happy Valley, I am not looking for what the city inspector checked off. I am looking for improperly sealed ducts, flashing that doesn't meet manufacturer specs, grading that sends water toward the foundation, and radon mitigation that was installed but never tested. Those are the things that show up in the report, before they become your problem after closing.

I hold Certified Master Inspector® certification, Oregon OCHI license #1898, and Washington DOL license #1856. Every inspection includes free thermal imaging.

Know What You Are Buying

Happy Valley Homes by Construction Era

Happy Valley's housing stock skews newer than almost any city in the Portland metro, but each era still has its own inspection profile. The build year on the listing is the best single predictor of what ends up in the report.

Pre-1965 Homes

Happy Valley's oldest homes are few and scattered. Before the city incorporated and began its rapid growth, this area was largely rural, with farmhouses and a handful of early residential properties on larger lots. If you are buying one of these homes, you are looking at a property that is 60 or more years old and has likely been updated piecemeal across multiple owners.

Galvanized steel supply pipes corrode from the inside out and are common in homes from this period. After 60-plus years underground, internal diameter is often significantly reduced, water pressure drops, and discoloration at fixtures is a regular finding. A full repipe lands between $10,000 and $25,000 depending on how big the house is. The cast iron waste line under the yard went in the same year, so a sewer scope belongs on the same visit.

The wiring in these houses reads in layers. A panel gets swapped, a circuit gets added for a kitchen remodel, and the original branch wiring behind the plaster stays right where it was. An old house takes me longer for that reason. There is more history to write down.

Common findings in pre-1965 homes
Galvanized steel supply pipes
Corroded internally. Restricted flow and discoloration common. Replacement $10,000 to $25,000.
Cast iron drain lines
Sixty years in the ground. Scale buildup, seepage at the joints, roots. Get a scope before you close.
Crawlspace moisture and wood rot
Foundations built before modern waterproofing do not shed our humidity well. Rot shows first at the sill and the joist ends.
Patchwork electrical updates
Owner-added circuits from several decades, not all of it to code. Common where a rural property later became a residential one.
Roofs at or past service life
Usually on a second or third covering by now. I record layer count and what life is left.

1965 - 1985 Homes

Happy Valley had very little residential development during this period. The area was still largely rural and unincorporated. The few homes from this era tend to sit on larger lots and carry characteristics common to rural Clackamas County builds of the time. Think stick-frame construction with older mechanical systems and often a mix of well and septic infrastructure that may have since been converted to municipal utilities.

Where polybutylene plumbing is present in this era across the Portland metro, it's less prevalent in Happy Valley than in cities that grew faster during the 1975 to 1995 window. That said, any home from this period that was built or remodeled in the late 1970s through mid-1990s could have it. I check for it on every inspection. Knowing before closing means you know what you are taking on. Finding out after means a $10,000 to $20,000 repipe on your own dime.

Common findings in 1965 - 1985 homes
Polybutylene plumbing (where present)
Less common in Happy Valley than in denser suburbs, but present in some remodeled or expanded homes. Degrades with chlorine exposure.
Federal Pacific and Zinsco panels
Documented safety concerns. Insurance carriers frequently flag or decline coverage on homes with these panels.
Legacy septic or well systems
Some rural-era properties converted to municipal systems, some have not. Specialist evaluation required for active private utilities.
Crawlspace moisture
Older vapor barriers and foundation drainage common on Clackamas County's hillside lots.
Roofing and sealant age
A house this age is usually on its second roof. I record covering age, condition, and remaining life.

1985 - 2005 Homes

This is where Happy Valley's residential development really started. The original core of the city, neighborhoods like the established subdivisions along Sunnyside Road, grew during this period. These houses are 20 to 40 years old now, which is the age where deferred work starts coming due all at once. They show well. The furnace, the roof, and the water heater that were all new in 1995 are running out of road together.

An early-2000s roof is at the back end of its 25-year rating. Window and door sealants have gone hard and split. CPVC supply line went into a lot of Oregon houses between 1995 and 2005, and the material gets brittle as it ages, worst where it runs near the water heater. Fittings crack first, so that is where the flashlight goes. Radon belongs on this list too, because Clackamas County soil does not care what year the house went up.

Common findings in 1985 - 2005 homes
CPVC plumbing brittleness
Becomes brittle with age and heat exposure. Cracking at fittings is the early warning sign.
Composite wood siding failure
1990s hardboard and wood-fiber siding absorbs moisture in wet climates. Fails from the bottom up.
Roofs at or beyond service life
Shingles rated for 25 years and nailed down around 2000 are out of warranty and out of life. Budget $10,000 to $20,000.
Radon in every era
Radon comes from the soil under new and old houses alike here. Test the one you are buying.
Deck ledger connection deficiencies
Attached decks from these years fail at the ledger more than anywhere else. I check the bolts, not the boards.

Jackson Hills and New Construction

Happy Valley's newest neighborhoods, Jackson Hills, Pleasant Valley, and North Carver, represent the city's ongoing growth edge. Plenty of buyers here skip the inspection because nobody has lived in the house yet. The city inspector who signed off checked framing and rough-in against a minimum standard at a few set points during the build. Nobody walked the finished house on your behalf.

On new Happy Valley builds the same four things keep turning up. Grading that runs water back at the foundation on a lot that was bare dirt last spring. Ductwork that was never sealed, or was sized wrong. Flashing missed at a window. Attic insulation with gaps in it. Your builder owns all four until closing, and a written report is what makes that stick.

The 11-month warranty inspection exists for one reason, which is getting defects on paper while the builder is still obligated to fix them. Your year starts the day you close. Book around month ten and you will have room to file.

Common findings in new construction
Grading and drainage toward foundation
A lot graded last season tends to settle back toward the house. Cheap to correct now, expensive once you own it.
HVAC installation defects
Open duct joints, a bath fan venting straight into the attic, a system nobody commissioned. All three show up in new Happy Valley builds.
Flashing deficiencies at windows and doors
Water gets behind the siding through a window that looks perfect from the driveway.
Insulation and ventilation gaps in attic
You cannot see them. The infrared camera can, and the builder still owns them if you catch it in time.
Radon (yes, even in new homes)
New construction here sits on the same ground as everything else. A passive stack does not prove anything on its own. The test does.

8 quick questions. No contact info required.

1 of 8
01

How old is the home?

You'll have the year built from the listing or the seller. Home age is the single biggest driver of inspection risk.

02

What did the roof look like from the street?

Look for curling shingles, dark patches, missing granules, or visible moss. A good look at the roof from the ground can tell you more than you'd think.

03

Did you notice any musty smell inside the home?

A musty or earthy odor is the most reliable clue buyers can detect about crawlspace moisture or mold, even without going under the house.

04

Did you see the electrical panel? What did it look like?

It's usually in a utility room, garage, or hallway. Federal Pacific (orange breakers) and Zinsco panels are known fire risks and still common in Portland-area homes from the 1960s to 1980s.

05

Did you notice any water stains on ceilings or walls?

Look near the corners of ceilings, under windows, and in bathrooms. Even old-looking stains matter, they show water has been in places it shouldn't be.

06

How did the overall condition of the home feel?

Trust your gut. A home that feels well-loved and maintained usually is. One that feels neglected almost always has deferred items hiding out of sight.

07

Did the home have a finished basement, addition, or garage conversion?

These are some of the most common places to find unpermitted work. A finished space isn't automatically a problem, but without permits, there's no record of whether it was done safely.

08

Where are you in your homeownership journey?

Know Your Neighborhood

Happy Valley Area by Area

Each part of Happy Valley has its own housing age, character, and inspection focus. Here is what buyers typically encounter in each area.

Jackson Hills
2000s - present

Happy Valley's luxury segment. Custom and semi-custom homes, many over $800,000. Premium finishes and larger lots, but high-end doesn't mean defect-free. These homes still need roofing, HVAC, flashing, and grading looked at closely. Radon testing still belongs on the list. Individual homes test high even in a Zone 3 county.

Pleasant Valley
Mixed eras, annexed 2023

A mix of older rural properties and new suburban development on land recently brought into the city. Some homes here still operate on septic and well water, which require separate specialist evaluations. Buyers should clarify current utility connections before closing. Soil settlement from recent development is also a factor to watch.

North Carver
Early-stage development, annexed 2023

Larger lots and ongoing construction on the city's outer edge. Private utilities are still common. Some buyers underestimate how much the transition from rural to suburban infrastructure matters when buying here. The inspection covers the home's physical condition. The utility and HOA picture needs to be understood separately.

Original Core (Sunnyside Area)
Early 2000s - 2010s

Established subdivisions with active HOAs, mature trees, and homes that are now 15 to 20 years old. Roofing systems are aging. Sealants around windows and doors have dried. CPVC plumbing from the early 2000s warrants attention. These homes need a different inspection focus than new construction across town.

HOA & Planned Communities
Mixed eras

Much of Happy Valley is HOA-governed. The inspection covers the home's physical condition. Reserve funding, pending assessments, and drainage connections to community infrastructure are separate due diligence items. Buyers in planned communities should review HOA documents before closing, not after.

Rural & Acreage Properties
Mixed eras

Larger lots on Happy Valley's edges, some with outbuildings, wells, and septic systems. These properties add scope to any inspection. Outbuildings are included. Well and septic evaluations require separate specialists. Wildfire risk is a factor on elevated or forested parcels in Clackamas County.

Clackamas County Risk Factors

What Makes Happy Valley Homes Different to Inspect

Happy Valley's geology, rapid growth, and EPA radon designation create inspection concerns that are specific to this part of the Portland metro.

Radon: Test Every Home

EPA rates Clackamas County as Zone 3, but individual homes still test high. The gas moves up out of the soil and enters through foundation cracks and crawlspace openings. You cannot see or smell it, and long-term exposure raises lung cancer risk. Buyers here often assume a builder-installed passive system settles the question. It doesn't. Those systems fail, and levels move with the seasons. Testing is the only thing that answers it, on a new house as much as an old one.

County zone is an average, not your result

Drainage on Developed Land

A lot of Happy Valley sits on ground that was farmland or timber a few years back. Soil that hasn't finished settling, paired with grading nobody established properly, moves water toward the house instead of away from it. In the newer neighborhoods I write this up more than almost anything else, and it gets costly once you own it. Downspout locations, surface slope, and window well drainage all go in the report.

Consistent finding in new subdivisions

Wildfire Risk

A significant portion of Clackamas County properties carry some wildfire risk. Jackson Hills, North Carver, and Pleasant Valley homes at elevation or on the city's edge can fall in moderate-to-high risk zones. I evaluate defensible space, exterior cladding materials, roof and gutter condition, and venting details that matter for wildfire exposure. Insurance carriers are paying close attention to this designation in Clackamas County, and it's worth understanding before you close.

Every Home Needs Its Own Test

Radon Testing in Happy Valley

EPA rates Clackamas County as Zone 3, but individual homes still test high. Radon is a colorless, odorless radioactive gas produced naturally by uranium breaking down in soil and rock. It seeps into homes through foundation cracks, crawlspace openings, and soil contact. You cannot smell or see it. The only way to know your level is to test.

Many Happy Valley buyers assume builder-installed passive radon mitigation systems make testing unnecessary. They don't. Passive systems can fail, and radon levels vary based on soil conditions, foundation type, and ventilation. Your neighbor's result doesn't predict yours. Every home needs its own test, new construction included.

We recommend radon testing on every Happy Valley inspection. If levels exceed 4 pCi/L (the EPA action level), a mitigation system typically costs $800 to $1,500. That's a reasonable item to address before closing. It's much harder to resolve after.

Happy Valley Home Inspection FAQs

Questions buyers in Happy Valley and Clackamas County ask most before booking.

Happy Valley home inspections start at $395 for homes up to 1,000 sq ft and scale by square footage up to $845 for homes up to 5,000 sq ft. Most homes here land in the $545 to $645 tiers. Free thermal imaging is included at every price point. See full pricing at trustedhome.org/pricing.
Yes, and in a city built this recently it may be the most useful thing you do. The city signed off on framing and rough-in against a minimum standard at a few points during the build. Nobody looked at the finished house on your behalf. On new Happy Valley builds I regularly write up grading that runs water at the foundation, duct work that was never sealed, flashing missed at a window, and gaps in the attic insulation. All of it is the builder's to fix until you close, and a written report is what makes that stick. There's also the 11-month warranty inspection, which catches what surfaces during your first year.
Yes. EPA rates Clackamas County as Zone 3, but individual homes still test high. Many Happy Valley buyers assume that builder-installed mitigation systems in new homes make testing unnecessary. They don't. Passive systems can fail, and radon levels shift seasonally. The only way to know your home's level is to test. Radon testing is $150 when added to your inspection. Standalone testing is $225.
It's an inspection timed to your builder's warranty. Most Happy Valley builders cover workmanship for a year from closing. Miss that date and every defect becomes yours to pay for. Booking near month ten leaves you enough runway to file the claims. Learn more about 11-month warranty inspections.
Plan on 2.5 to 4 hours. Size, age, and condition all move that number. A Jackson Hills house or one of the original core subdivisions usually sits mid-range. An older Pleasant Valley or North Carver property with outbuildings takes longer, because there's more to walk. Come for the whole thing or just the walkthrough at the end, whichever suits you.
Thermal imaging is included at no extra charge on every inspection. The infrared camera picks up duct leaks, thin spots in insulation, and moisture behind finishes that nothing else on the truck can see. On a brand new Happy Valley build it earns its keep every time. Learn more about thermal imaging.

Multnomah County home inspections. Portland and the rest of Multnomah County are full of older housing stock, including 1920s craftsman bungalows in SE Portland, Pearl District lofts, and mid-century homes in NE Portland. Older homes mean knob-and-tube wiring, cast iron drains, and aging foundations. I’ve inspected hundreds of homes across Multnomah County and know exactly what to look for in each neighborhood.
