What should I check in a 1990s St. George house?

Houses built in St. George in the 1990s are generally sound, sensibly laid out and on larger lots than what is being built now. They are also at the age where several original systems reach the end of their service lives within a few years of each other.

That is the thing to plan for. Not a defect, exactly. A sequence of replacements that arrives whether or not you budgeted for it. A house from this era that has had nothing done is not a bargain, it is a schedule.

For an older house again, the issues shift and I have covered those separately in what to check in a house built in the 1970s.

The tile roof problem, which is the big one

This is the item most specific to southern Utah and the one most frequently missed.

Concrete and clay tile is common on homes of this era here, and the tile itself lasts a very long time. The underlayment beneath it does not. It is the underlayment that actually keeps water out; the tile protects it from sun and impact.

So a roof can look immaculate from the street while the layer doing the work has become brittle and begun to fail. A visual inspection from the ground tells you almost nothing, and a general home inspection may not tell you much more.

Replacing underlayment means lifting and re-laying the tile, which is labor-intensive and not cheap. On a house of this age with original underlayment, it is a real number and it belongs in your offer calculation rather than in a surprise two years from now.

Ask directly: has the underlayment ever been replaced, and is there documentation? If the answer is no or nobody knows, get a roofer on the roof before your due diligence deadline. What roofs in southern Utah are actually made of covers why the material mix here differs from what northern buyers expect.

Supply plumbing

Some houses from this era were plumbed with polybutylene supply lines, a gray flexible pipe used widely until the mid-1990s. It has a known history of failure, insurers treat it differently, and some will not write a policy on a house that still has it.

Find out what the supply lines are. The pipe is identifiable, often visible at the water heater or in the garage, and an inspector will know it on sight. If it is present, that is a budget item and potentially an insurance conversation before you commit.

Even where the supply plumbing is fine, fixtures, valves and the water heater from this era are long past their expected lives. Hard water in this county is unkind to all of it, and the cumulative effect over thirty years is real.

The cooling equipment

Air conditioning is not optional here, and in this climate the equipment works hard for a long season. Why you genuinely need it is its own subject, but for an older house the relevant point is that the original unit is certainly gone and the replacement may itself be aging.

Ask for the age of the current system and the service records. A system installed early in the 2000s has had a full life here. Ask also about the ductwork, which is frequently original and frequently leaking into an attic that reaches extraordinary temperatures in summer, which means you are paying to cool a space you do not live in.

System	Typical state in a 1990s house	What to ask
Tile roof	Tile fine, underlayment often original	Has underlayment been replaced
Supply plumbing	Sometimes polybutylene	What material, and has any been repiped
Cooling	On the second unit, possibly aging	Age, service history, duct condition
Water heater	Replaced at least once	Age, and whether it is in the garage or attic
Windows	Builder-grade, seals failing	Any fogged units, any replacements
Stucco	Generally sound, details vary	See below
Landscaping	Often original lawn, high water use	What it costs to run

Windows

Builder-grade dual-pane windows from this period are at the age where seals fail, which shows up as permanent fogging between the panes. It is a comfort and efficiency issue rather than a structural one, and in this climate the efficiency part is not trivial.

Walk the house and look at every window from the outside in good light. Fogged units are easy to spot once you are looking, and a house with several is telling you about a replacement cost.

Stucco, where the house meets the ground

Stucco on houses of this era is generally sound. The problems are almost always in the details, and in particular where the stucco meets the soil, thirty years is plenty of time for landscaping to be built up against a wall by a succession of owners.

I have gone through what to look for in should I worry about stucco on a St. George house. The short version for a house of this age: walk the full perimeter and look at the bottom edge.

Landscaping, which is a running cost

Many houses from this era were landscaped with lawn, because that is what was done at the time. In this climate a large lawn is an ongoing expense and it is the single largest variable in what the property costs to run.

That is not necessarily a reason to avoid the house. It is a reason to ask what it costs to water, and to price a conversion if you intend to make one. What it takes to keep a yard alive here sets out the arithmetic.

What makes these houses worth buying anyway

Lot size, mostly. Houses from this era generally sit on more land than equivalent new construction, in older neighborhoods with mature trees that are genuinely valuable in this climate and impossible to buy new.

The construction is usually solid, the layouts are often more generous in the rooms that matter, and the neighborhoods have finished settling into what they are going to be.

I am Kelsey Earl, a Realtor with Keller Williams South Valley. What I tell clients looking at this era is simple: the house is probably fine and the systems are probably due. Price the systems, do not fear the house.

What to do with this

Get the roof looked at by a roofer, not only by a general inspector, and ask specifically about underlayment.

Identify the supply plumbing material before you remove contingencies.

Get ages and service records for cooling, water heater and roof, in writing.

Then build those numbers into what you offer rather than discovering them later. If you want help working out what a specific house of this vintage realistically needs, send me the address.
