Old Town Longmont: Authentic Historic Living in Reach
Old Town Longmont is the authentic, in-band version of walkable historic living: an 1870s grid around a working Main Street where the walkability was never designed, just never lost. Genuine old homes and a lighter historic layer than Boulder's, at a Longmont price.
If you want the real thing, an old house on an old grid a short walk from a working Main Street, Colorado gives you two honest options and one expensive one. Old Town Longmont is the accessible one. It's the original core of a town platted in 1871, a neighborhood of genuine Victorians and bungalows where the walkability was never planned into existence. It was simply never taken away. That is the whole case for living in Old Town Longmont, and it's a different case than the two neighborhoods buyers usually put next to it.
Old Town Longmont is the historic core of Longmont: the original 1870s grid of Victorian and Craftsman homes on either side of a real, working Main Street. It offers authentic walkable historic living at a Longmont price, without the blanket design-review regime of a Boulder historic district or the covenants of a designed new-urbanist community. The trade is old housing stock and honest diligence.
The walkability here was never designed. It was never lost.
The appeal of Old Town Longmont is that nobody engineered it. The 1871 town plan put shops on Main Street and homes on a grid around them, and that grid was never bulldozed for cul-de-sacs. So the short walk to a coffee shop or a brewery is inherited, not built to spec, which is exactly what separates Old Town from a designed neighborhood like Prospect and from a price-gated one like Boulder's Mapleton Hill.
Two neighborhoods get compared to Old Town, and the contrast with each one tells you what Old Town actually is. Prospect New Town, on the south edge of Longmont, is a genuinely walkable place, but it was drawn up in the 1990s to be that way, with a planned town center and design covenants that hold the look in place. Old Town's Main Street isn't a planned amenity. It's the actual downtown of the city, shops and restaurants and brewers in brick buildings that have stood since the 1880s. Mapleton Hill in Boulder is the other comparison: same era, same authentic old grid, but it sits under a strict city historic-district regime and trades mostly above what a move-up buyer can spend. Old Town gives you the authenticity of Mapleton with a lighter touch and a Longmont price. Read the three side by side.
| Walkable historic living | Old Town Longmont | Prospect New Town | Boulder historic (Mapleton Hill) |
|---|---|---|---|
| How the walkability got there | Inherited: an 1870s Main Street grid that was never un-built | Designed: a 1990s New Urbanist plan built to be walkable | Inherited: an 1880s streetcar-era grid |
| The historic layer | National Register (honorary) plus voluntary, opt-in local landmarking; ordinary exterior work isn't reviewed | HOA, design covenants, and design review, on every home, for life | Blanket local historic district; every exterior change reviewed, teardown can be blocked |
| The downtown | A real, working Main Street at the edge of the grid | A small planned town center inside the neighborhood | Downtown Boulder, a walk to the south |
| The stock | Genuine 1880s–1930s Victorians, Foursquares, bungalows | New-build, built to look traditional | Genuine 1890s–1930s Victorians |
| Price band | Entry cottages below the move-up band; restored homes reach into it | In-band for a move-up buyer | Mostly above the $800K–$1.5M band |

What living in Old Town Longmont actually is
Old Town Longmont is the original one-square-mile townsite platted in 1871 by the Chicago-Colorado Colony and named for the view of Longs Peak. Homes sit on a tight grid on both sides of Main Street, split into two National Register neighborhoods: the East Side, mostly 1800s Queen Anne Victorians, and the West Side, early-1900s Foursquares and bungalows. The downtown is a certified Creative District.
The bones of the neighborhood are the 1871 plan itself. The colony laid out stores along Main Street and homes on a grid spreading east and west, with parks worked in. After an 1879 fire took part of the 300 block, the downtown was rebuilt in brick, which is why Main Street still reads as a solid nineteenth-century street. The residential blocks around it are two officially recognized areas. The East Side Historic District, roughly 4th to 8th Avenue and east toward Atwood, was listed on the National Register in 1986 for its 67 Queen Anne and 19th-century homes. The West Side, from Main west toward Bowen, was listed in 1987 for 118 early-1900s houses in Edwardian and American Foursquare styles on somewhat larger lots. Together they're what people mean by the old town Longmont neighborhood.
The other half of the case is the downtown itself. Longmont's Main Street has been rebuilt over the last decade into a working commercial district, and in 2014 it was certified as a Colorado Creative District, with galleries, an arts center, restaurants, and a dense run of breweries, cideries, and distilleries. For a buyer who wants to walk out the front door to somewhere real, that district is the draw, and it's a fact about the place, not about who lives there. The flip side is worth walking before you commit: the closer to Main Street and the rail line, the more you hear it, from First-Friday and festival traffic to weekend brewery-district crowds to the freight-train horns of an old railroad town (whether a given block sits in a quiet zone varies, so check it on foot at night).
The historic layer is lighter than a Boulder district
Living inside an Old Town Longmont National Register district does not, by itself, restrict what you do with your house. National Register status is largely honorary, and Longmont applies design review only to homes their owners have voluntarily landmarked. That's the key difference from Boulder's Mapleton Hill, where every home in the district is under mandatory review. The one real exception in Old Town is demolition.
This is the part most buyers get backwards, so it's worth getting exactly right. Old Town's East Side and West Side are National Register districts, and under federal rules a National Register listing places no restriction on a private owner using private money. The City of Longmont's own guidance says it plainly: there are no added restrictions or review for a home in a Register district unless the owner is pursuing a historic financial incentive.
The layer that does have teeth is separate, and it's voluntary. Longmont was Colorado's first Certified Local Government for historic preservation, and its preservation program, established in 1971, has since designated more than 120 individual local landmarks. But that designation is opt-in: the city can only landmark a property with the owner's consent. A locally landmarked home does need a Certificate of Appropriateness for exterior work like paint, windows, a reroof, or an addition. The great majority of Old Town homes are not individually landmarked, and for those homes, ordinary exterior work isn't design-reviewed at all. That is the accessible middle in one sentence: the character of a historic district, without the blanket rulebook of one.
There's one citywide exception worth knowing before you buy, and it isn't small. Under the municipal code, demolishing a building more than 50 years old inside the original townsite plat, landmarked or not, goes to the Historic Preservation Commission for review, and the commission has postponed a teardown of an older home while the owner documented the case. It's a review that can delay, not the outright denial a contributing home faces in Mapleton Hill, but if your plan is to scrape an old lot and build new, confirm exactly what's allowed on that parcel first.
What owning a century-old home here asks
The trade for authentic old character in Old Town Longmont is old-home systems. A house from the 1880s to the 1920s can carry aging wiring, old supply and waste plumbing, a buried sewer lateral, and a foundation that has settled over a century. None of it is a dealbreaker, and it's lighter than a review-gated Mapleton restoration, but it's a real budget line. The northern Front Range is also EPA radon Zone 1.
An old house is a beautiful thing and a mechanical one, and the systems list runs the same as the one our Mapleton Hill guide itemizes in full, without the mandatory review that makes fixing them slower there. The item to find first is knob-and-tube wiring, still live in some homes this age: a carrier may refuse to write it, and a rewire runs into five figures. Cast-iron and galvanized plumbing has a service life measured in decades and is often near the end of it, and the clay sewer lateral running to the main is its own risk, so add a sewer scope to the inspection. These homes sit on expansive clay soils, and unreinforced stone or brick foundations, dirt-floor cellars, and crawlspaces move differently than a poured slab, so give the foundation a specific look. Every home here is old enough to carry lead paint and, often, asbestos in plaster, tile, or pipe wrap, which are health items and the real reason a renovation on an old house costs more and moves slower than on a new one. And because the northern Front Range sits in EPA radon Zone 1, the highest, a radon test and possible mitigation are standard here, not optional.
One daily-life adjustment a move-up buyer should picture honestly: many Old Town homes have no attached garage, only detached alley access or street parking, on a tight grid where winter snow and downtown-event parking get real. If a two- or three-car attached garage is on your list, walk the block before the porch closes the deal.
The honest framing on the rest is that this is real work but not review-gated work. Unless the specific home is a voluntary local landmark, you're free to rewire, replumb, and modernize on your own schedule, which is a materially lighter path than restoring a home inside a mandatory-review district. You still pull City of Longmont permits, and opening walls on an old house can trigger current-code upgrades, so "freely" means no design review, not no permit. Get an old-home inspection that looks specifically for these systems, and get the insurance quote inside your inspection window rather than the week before closing.
And there's one neighborhood-specific risk the systems inspection won't flag: flood. Old Town is the oldest, most river-adjacent grid in a town the 2013 St. Vrain flood hit hard. The core blocks are likely outside the mapped floodplain, but the southern margin toward the St. Vrain, and pockets near Left Hand Creek, are the real question, and the city's Resilient St. Vrain channel work and FEMA remapping have moved parcels in and out of the flood zone since. So pull the FEMA and City of Longmont floodplain status for the exact address. If it falls in a Special Flood Hazard Area, a federally backed loan will require flood insurance, and you want that priced inside your inspection window, not after.
Who Old Town Longmont fits
Old Town Longmont fits a move-up or relocating buyer who wants authentic historic character and a real downtown at the door, at a Longmont rather than a Boulder price, and who's comfortable owning and maintaining an old house. It fits less well for a buyer who wants a large lot and garage, a low-maintenance new build, or the strict permanence of a protected Boulder historic district.
Old Town fits you if
- You want a genuinely old home, a Victorian or a bungalow, and a short walk to a working Main Street rather than a planned town center.
- You'd rather buy authentic historic character inside your budget than shop above it for a Boulder historic address.
- You're comfortable owning an older house and budgeting for its systems as an ongoing line item.
- You value being inside the City of Longmont, with city water, sewer, and services rather than a well and septic.
Look elsewhere if
- You need a large lot, a three-car garage, or space for an RV; the old grid is tight and alley-loaded in places.
- You want a low-maintenance, modern house you never have to think about.
- You specifically want the legal permanence of a strict historic district, where no neighbor can ever redevelop next door.
- Your plan depends on scraping an old lot and building new.
How to check out an Old Town Longmont home before you make an offer
Diligence on an Old Town Longmont home has four moves a newer-house purchase skips: confirm whether the specific parcel carries a voluntary local landmark designation, inspect specifically for old-home systems plus radon and the sewer lateral, verify the school assignment by address, and confirm the in-city utilities. Then price the specific home against real comparable sales, not a neighborhood median.
Confirm the parcel's historic status
Check whether the specific home is an individually designated local landmark, which carries a Certificate of Appropriateness for exterior work, or simply sits inside a National Register district, which doesn't. If you intend any major change, and especially a demolition, confirm exactly what the municipal code requires on that parcel before you write the offer.
Get an old-home systems inspection, with a sewer scope and a radon test
The same century-old-systems bill described above: check the wiring and the electrical service size, the cast-iron or galvanized plumbing, and the buried sewer lateral, and test for radon (Zone 1). Line up the insurance quote before your inspection window closes, since active knob-and-tube can make a carrier balk or surcharge.
Verify schools by exact address
Old Town is served by St. Vrain Valley Schools; assignments run by boundary and can shift, so confirm the specific elementary, middle, and high school for the address rather than assuming it from the neighborhood name.
Confirm the in-city utilities and pull the tax bill
Old Town is squarely inside the City of Longmont, so you get city water, sewer, and services with no well or septic. Our guide to moving to Longmont walks the wider city-versus-county lines a Longmont address can turn on.
Pull the floodplain status by address
Old Town runs along the St. Vrain corridor, and the 2013 flood plus the FEMA remapping since make flood status a per-parcel question, not a neighborhood one. Check the FEMA and City of Longmont floodplain maps for the exact address, and price flood insurance inside your inspection window if it falls in a Special Flood Hazard Area.
About this data
A restored two-story Victorian and a one-bedroom worker cottage don't share a price, so there's no honest single "Old Town median" to hand you. This is a small pocket of varied old stock, roughly 1,000 to 3,000 square feet, and averaging a restored Victorian and a one-bedroom cottage yields a number no house on the block would sell for. The useful point is comparative: Old Town generally trades below Boulder's historic neighborhoods, so authentic walkable historic living lands inside a move-up budget here in a way it usually can't in Boulder, though the restored high end of the neighborhood reaches into and past that band.

Frequently asked
Is Old Town Longmont a historic district with strict design rules like Boulder's Mapleton Hill?+
No, and this is the key difference. Old Town's East Side and West Side are National Register historic districts, which is largely honorary: a National Register listing places no restriction on a private owner using private money. Boulder's Mapleton Hill, by contrast, is a mandatory city historic district where every home's exterior changes are reviewed. In Old Town, design review only applies to homes whose owners have voluntarily landmarked them.
Do I need city approval to remodel or repaint a home in Old Town Longmont?+
For most homes, no. Longmont's local landmark designation is opt-in and requires the owner's consent, and only a designated local landmark needs a Certificate of Appropriateness for exterior work like paint, windows, a reroof, or an addition. The large majority of Old Town homes are not individually landmarked, so ordinary exterior work is not design-reviewed. The one real exception is demolition: tearing down a building over 50 years old inside the original townsite plat goes to the Historic Preservation Commission for review, so confirm the specifics on the exact parcel.
What kinds of homes are in the Old Town Longmont neighborhood?+
Genuinely old ones. The East Side, listed on the National Register in 1986, is mostly 19th-century Queen Anne Victorians. The West Side, listed in 1987, runs to early-1900s American Foursquares, Edwardian styles, and Craftsman bungalows on somewhat larger lots. You'll also find Colonial Revival homes and historic worker cottages, typically from about 1,000 to 3,000 square feet, on a tight grid with mature trees and alleys in places.
Is Old Town Longmont in the City of Longmont, and what schools serve it?+
Yes. Old Town is the original core of the City of Longmont, so it takes city water, sewer, and services, with no well or septic to manage. Schools are St. Vrain Valley (SVVSD / RE-1J); Central Elementary, built in 1878 and itself a local landmark, sits in the neighborhood. Assignments run by boundary and can change, so verify the exact elementary, middle, and high school for a specific address with the district.
Is Old Town Longmont affordable, or has it priced out?+
It's the accessible version of authentic historic living, not a uniform price. The stock is too varied to average honestly: entry cottages trade below the $800K–$1.5M move-up band, while a restored two-story East-Side Victorian reaches into and sometimes past it. The comparative point is what matters: Old Town generally trades below Boulder's historic neighborhoods, which is what keeps genuinely old walkable living inside a move-up budget here. Start with our Longmont housing market report, then get a comparative market analysis on the specific home.
What do buyers underestimate about a 120-year-old Old Town home?+
The systems and the flood check. A house from the 1880s to the 1920s can carry aging or knob-and-tube wiring, old plumbing, a clay sewer lateral, lead paint, and a foundation that has settled on expansive soil, and Boulder County is EPA radon Zone 1. Because Old Town runs along the St. Vrain, flood status is also a per-parcel question after 2013 and the remapping since. None of it is a dealbreaker, and because most homes aren't review-gated you can modernize on your own schedule, but it's real diligence a new build skips, so inspect specifically and add a sewer scope, a radon test, and a floodplain check by address.
The bottom line
Old Town Longmont is the version of walkable historic living you don't have to design from scratch or overpay for. The grid, the Victorians and bungalows, and the walk to a real Main Street are all authentically old and intact, the historic layer is far lighter than a Boulder district, and the price sits inside a move-up budget. The trade is honest and it's old: aging systems, a tight lot, and diligence a new build skips. For a buyer who wants the real thing at a Longmont price, that's one of the better trades on the northern Front Range.
That "real thing at a Longmont price" is only a good trade on the specific house, though, which is where we come in.
Looking hard at an Old Town block?
The step that protects you is knowing exactly what the house's age asks of you: the systems, the in-city utilities, and whether that specific parcel carries a voluntary landmark tag, all before you make an offer. We read old Longmont houses honestly against the rest of the corridor.
Written by the True North Boulder team, a team at eXp Realty. On an old Longmont block the work is unglamorous: we walk the specific home's systems and confirm its landmark status before you write, not after, instead of trusting the brochure version. We work with $800K–$1.5M move-up buyers across Boulder and the northern Front Range; hire us and a written buyer-agency agreement goes in place up front, on terms you set. We make no price promises, only that the numbers here trace to a current source for the specific home.
