Littleton 80123 vs. 80128 in 2026: $579,830 vs. $578,830 Medians, but 57% vs. 68% Detached Houses
Quick answer: Littleton 80123 and 80128 sold at almost the same median, $579,830 vs. $578,830 for the three months ending September 2026, per Redfin. The homes differ. In Census survey data, 57% of 80123's homes are detached houses vs. 68% in 80128, and 80123 has more than twice the share in buildings of 5 or more units.

When two zipcodes post the same median price, buyers tend to treat them as interchangeable. In 80123 and 80128 that would be a mistake. The price line matches, but what stands behind it does not: the share of detached houses, how old the homes are, how many bedrooms they have and which county runs the address all split between the two.
Prices come from Redfin's 80123 and 80128 housing market pages, which I checked on October 23, 2026; they cover every home type sold. The housing figures come from the Census Bureau's American Community Survey 2020-2024 five-year estimates and count every home, owned or rented, so they describe the housing stock, not only what sold this year. The DMHP searches linked below list houses from $600,000, a bit above both medians.
How close are 80123 and 80128 on price in 2026?
Within $1,000 on the median and $8 on the square foot, for the three months ending September 2026.
- 80123: $579,830 median sale price, down 3.4% from a year earlier; $276 a square foot, up 7.0%; 163 homes sold in September; 31-day median time on market
- 80128: $578,830 median sale price, also down 3.4%; $284 a square foot, up 2.5%; 140 homes sold in September; 24-day median time on market
At those per-foot medians, $650,000 covers about 2,355 square feet in 80123 and about 2,289 in 80128, a 66-square-foot gap that condition and basement finish can erase on any one house. To test it on live listings, open the Littleton 80123 houses for sale beside the Littleton 80128 houses for sale.
What kinds of homes make up each zipcode?
80128 leans harder toward single-family homes: 84.1% of its homes are detached or attached single-family, against 67.6% in 80123.
- Detached houses: 57.0% of 80123's 19,953 homes vs. 67.9% of 80128's 14,678
- Attached single-family homes, such as townhomes: 10.5% vs. 16.2%
- Buildings with 2 to 4 units: 3.6% vs. 2.4%
- Apartment or condo buildings with 5 or more units: 28.5% vs. 13.4%
That last line explains a lot. Redfin's median mixes condos with houses, and 80123 has about 5,684 homes in buildings of 5 or more units against about 1,973 in 80128. My read is that 80123's bigger condo and apartment share pulls its all-types median down, so a detached 80123 house can run above that $579,830 line. That is an inference, not a measured price, so check recent detached sales on the specific street.
How old are the homes in 80123 vs. 80128?
Both are mostly 1970s to 1990s housing, but 80128 is older on balance: its median home was built in 1983, against 1986 in 80123.
- Built 2000 or later: 20.9% of 80123's homes vs. 13.2% of 80128's
- Built 1980 to 1999: 43.4% vs. 43.6%
- Built in the 1970s: 24.2% vs. 32.4%
- Built before 1970: 11.5% vs. 10.7%
The 1970s line is the real split. Nearly one home in three in 80128 dates from that decade. The Census survey also counts about 279 homes in 80123 built in 2020 or later and none in 80128, with a margin of error of plus or minus 29 there, so treat brand-new construction in 80128 as rare in this data rather than absent. These are survey estimates with margins of error, and year built is reported by the people who answer the survey.
How many bedrooms do homes in each zipcode have?
More of 80128's homes have room to spread out: 74.4% have three or more bedrooms, against 62.1% in 80123.
- Four or more bedrooms: 40.9% in 80128 vs. 32.9% in 80123
- Studio or one bedroom: 4.2% in 80128 vs. 14.8% in 80123
The bedroom split tracks the home mix. In raw counts 80123 is the bigger zipcode, with about 6,569 homes of four or more bedrooms against about 6,004 in 80128, so the difference is in share, not in supply. The Littleton houses from $600K to $800K search covers both zipcodes if a fourth bedroom is on your list.

What changes when a Littleton house was built before 1978?
The seller owes you a lead-based paint disclosure, and you get a 10-day window for a lead inspection unless both sides agree in writing to change or waive it.
Under the EPA's lead-based paint disclosure rule, which covers most housing built before 1978, the seller must hand over the EPA lead pamphlet, disclose any known lead-based paint and share any reports on it before you sign. With 32.4% of 80128's homes and 24.2% of 80123's built in the 1970s, plus about 11% of each built earlier, a sizable share of homes in both zipcodes fall under the rule. The Census bins run by decade, so a 1978 or 1979 house sits in the 1970s count but falls outside the rule. Ask for the disclosure early, and decide before the contract whether you want the inspection window.
Which counties does each zipcode cover?
80123 spans three counties and 80128 sits almost entirely in one, by land area in the Census Bureau's 2020 relationship files.
- 80123: 49.6% Jefferson County, 31.4% Arapahoe County, 18.9% City and County of Denver
- 80128: 90.1% Jefferson County, 9.9% Arapahoe County
The county decides which assessor values the house and where the tax bill and property records live. Inside 80123 the same files also put parts of the land in the towns of Bow Mar and Columbine Valley, the City of Littleton and the City of Lakewood. Land shares are not home counts, so confirm each address: the Jefferson County Address Lookup and Jefferson County Assessor records for Jefferson addresses, the Arapahoe County Assessor for Arapahoe ones, and Denver's property search for Denver ones.

Start from the county: with 90.1% of 80128's land and 49.6% of 80123's in Jefferson County, the Jeffco articulation areas lookup is the usual first stop for the exact address.
Use the Jeffco articulation areas lookup for Jefferson County addresses and the Denver Public Schools boundary page for an 80123 address in Denver.

Should you buy in Littleton 80123 or 80128?
At the same median price, 80128 fits a buyer who wants a detached or attached house with three or more bedrooms; 80123 fits a buyer who wants newer construction or a condo option.
Choose Littleton 80123 if:
- You want a better shot at a home built in 2000 or later (20.9% of its homes)
- A condo or a smaller home is on the table alongside houses
- You are fine checking which of three counties the address sits in
Choose Littleton 80128 if:
- You want a zipcode where single-family homes make up 84.1% of the housing stock
- You want three or more bedrooms to be the norm, as in 74.4% of its homes
- You want one county, Jefferson, which covers 90.1% of its land
Keep looking if:
- You need a home built in the last five years in 80128
- You want to skip lead disclosure forms and older systems; a house built in 2000 or later narrows both zipcodes a lot
- Your budget is far above $1M; widen to 80127 and Morrison 80465
Broker view: "When two zipcodes share a median, I stop looking at the median. In 80123 and 80128 the home type and the decade it was built tell you more about what $650,000 gets." - Nick Ahrens, eXp Realty, LLC
