Aging US housing stock and repair demand

The US housing stock keeps getting older

New construction adds only a sliver of homes each year, so the stock ages almost one year per year. NAHB's analysis of American Community Survey data puts the median age of owner-occupied homes at 42 years in 2024, up from 31 in 2005^[1]. Around 47% of owner-occupied homes were built before 1980, including about 34% built before 1970, while homes built from 2020 to 2024 account for only about 4% of the stock^[1].

For home service businesses this is a structural tailwind. Most homes are well past the life of their original roof, water heater, HVAC equipment and garage door opener, and many have wiring, plumbing and insulation that were never designed for today's loads and expectations. Every one of those systems will be repaired or replaced, by someone, on a schedule driven partly by age and partly by failure.

Where homes are oldest

Age is not spread evenly. New York has the oldest owner-occupied homes with a median age of 64 years, followed by Massachusetts and Rhode Island at 59 each; Nevada is youngest at 25 years, followed by Texas at 28^[2]. NAHB describes the age of the stock as an important indicator for the remodeling market, since older homes tend to be less energy-efficient and more likely to need repairs^[2].

Inside a state the spread is wider still. An inner suburb built in the 1950s and a new subdivision twenty minutes away need different services. That is why national averages are only the start: the useful number is the year-built profile of the ZIP codes your trucks already drive.

What older homes mean for each trade

• Lead paint: EPA's Renovation, Repair and Painting Rule requires anyone paid to disturb painted surfaces in pre-1978 homes to be certified and workers trained in lead-safe practices^[3]. That covers far more than painters: electricians cutting into walls, HVAC installers and window or door replacers can all be affected.
• Garage doors: the federal entrapment-protection standard applies to automatic residential operators made on or after January 1, 1993^[4], so very old openers deserve a safety conversation.
• Energy: ENERGY STAR says sealing and insulating ducts can improve heating and cooling efficiency by up to 20%^[5], a strong offer for older duct systems.
• Safety: an estimated 344,600 residential building fires occurred in 2023^[6], and more than 400 Americans die each year from unintentional non-fire carbon monoxide poisoning^[7]. Inspections of old electrical and combustion equipment are genuine safety work.

Turning home age into planned work

1. 01

   Get the year-built profile of your area

   On data.census.gov, the American Community Survey publishes year structure built and median year built by ZIP code tabulation area and county.

2. 02

   Add year built to customer records

   Ask on every new booking (“roughly when was the home built?”) and fill gaps from public property records where your state allows. Store it as a field, not a note.

3. 03

   Build age-based offers

   For example, a panel and wiring check for homes before a certain decade, duct testing for older HVAC systems, an opener safety check for old garage doors.

4. 04

   Train the office to ask

   Year built changes the questions a CSR should ask and the parts a technician should carry.

5. 05

   Measure response by age band

   Track bookings and sales from each offer by home age, then keep the offers that work.

Example: a fictional HVAC company finds that two of its five ZIP codes have a median year built in the 1960s and the other three in the 1990s. It sends a duct-sealing and repair-or-replace mailer only to the older ZIP codes, and a maintenance-agreement offer to the newer ones. The older-home campaign produces fewer leads but larger tickets; the newer-home campaign grows agreements. Neither would have worked as well sent to everyone.

What the age data does not tell you

Year built describes the structure, not its systems. A 1965 house may have a two-year-old heat pump, a new roof and a rewired kitchen; a 2005 house may still run its original water heater and opener. Treat home age as a prompt to ask better questions, not as a diagnosis. The age of each system, recorded on the customer record when a technician sees it, is far more valuable than the age of the house, and it is the field most companies fail to fill in.

Remodeling history matters too. A home that was renovated in the 1990s may have newer wiring in one wing and original circuits in another. Ask, photograph and note what you find, so the next technician does not start from zero.

Who makes the repair decision

The homeownership rate was 65.5% in the third quarter of 2026^[8], so roughly two in three homes are owner-occupied and the owner decides and pays. In rented homes the decision sits with a landlord or property manager, who weighs repair cost against rent and vacancy; the rental vacancy rate was 7.6% in the same quarter^[8]. Older rental stock often needs the same work as older owned homes, but sales conversations differ: landlords want reliability, documentation and quick turnaround between tenants rather than comfort upgrades.

Record who you are dealing with on every job. An owner-occupant, a landlord and a property manager need different booking questions, different approvals and different invoices, and a company that handles all three well can build steady work across the older parts of its service area.

Older homes, insurance and damage

Older roofs and systems meet weather and pests with less margin for error. Wind and hail caused the largest share of homeowners insurance claims from 2018 to 2022, at 2.8% of insured homes a year, followed by water damage and freezing at 1.6%^[9]. Termites cause more than $6.8 billion in US property damage each year, costs not covered by homeowners insurance^[10]. Inspection-led maintenance in older homes is the work that keeps these events from becoming emergencies.

Be clear with customers about what insurance does and does not cover. Contractors who explain that wear and pest damage are usually maintenance items, while sudden storm damage may be claimable, build trust and avoid jobs stalled by denied claims.

Questions for the office to ask on older homes

1. Roughly when was the home built, and has the system we are coming to see been replaced?
2. Has any work been done on the walls, ceilings or windows we will need to open? (Triggers a lead-safe check on pre-1978 homes.)
3. Is the electrical panel original, as far as you know?
4. Is there an attic, crawl space or basement the technician will need to reach, and is it accessible?
5. Do you own the home, or should we contact a landlord or property manager to approve the work?

Those five answers let the dispatcher send the right technician with the right equipment and time slot, and let the estimator price lead-safe work, access and likely extras up front instead of after the first visit.

Talk about age without scaring customers

Age is a reason to inspect, not proof of failure. A 40-year-old house with a well-maintained replacement system is not an emergency. Keep the conversation factual: what you checked, what you found, photos, and options with prices. Customers respond to evidence and to choices; they resent fear-based selling, and reviews punish it.

Homeowners are already spending on maintenance: Angi found 44% completed at least one maintenance project in 2025^[11]. Position your age-based offers as planned maintenance that avoids an emergency, and most of the work will come on your schedule instead of the night something breaks. See homeowner repair spending for how that spending splits between planned and emergency work, and the home services market overview for the trade-by-trade picture.
