Finding the right Denver apartment website can save weeks of scrolling. Denver renters can search online through general listing sites, a free apartment-locator service, and public city and state housing tools. We compared six Denver apartment websites based on three things: how much real building-level detail they give you, how Denver-specific the information is, and whether you can actually use the site without talking to anyone first. Updated October 2026.
Denver Apartment Websites Compared
1. DenverApartmentBuildings.com
Best for: comparing buildings side by side before you ever contact anyone.
DenverApartmentBuildings.com is a free, independent directory of 194 apartment buildings across twelve neighborhood categories in the City and County of Denver (four of them in Glendale, a separate city surrounded by Denver), with structured, per-building data: floor count, unit count, year built, nearest RTD rail station and its straight-line distance, and amenities like pet policy, in-unit laundry, parking, air conditioning, and fitness center. It also publishes a citywide data breakdown — amenity rates, building age, and neighborhood counts — so you can see how a building or neighborhood compares before narrowing your search. There’s no locator to call and no lead form to fill out; it’s a free, self-serve reference built around the buildings themselves rather than individual unit listings, and it carries no rents, rankings, reviews or paid placement.
2. AptAmigo
Best for: renters who want a free, personal apartment hunter.
AptAmigo is an apartment-locating service that operates in Denver among nine U.S. cities. A locator contacts you to discuss your needs, does the searching, recommends buildings, and schedules tours — the service is free to renters because, per AptAmigo, it provides marketing support to the buildings it partners with. It’s a good fit if you’d rather hand off the legwork than do your own research, though you’re working through an agent rather than browsing raw data yourself.
3. Denver Housing Authority
Best for: renters looking for Housing Choice Vouchers or other affordable-housing programs in Denver.
The Denver Housing Authority (DHA) describes itself as a quasi-municipal corporation with a portfolio of over 13,000 units, and states that its mission is “to develop and provide high-quality, affordable housing with responsive services.” It provides Housing Choice Vouchers and lists affordable and subsidized housing options, with an online My Housing Portal for residents.
4. ColoradoHousingSearch.com
Best for: a free statewide search that includes affordable and accessible units.
ColoradoHousingSearch.com calls itself Colorado’s housing search site and is free to use. It carries the logos of the Colorado Housing and Finance Authority and the Colorado Department of Local Affairs. You can search by address, city, county, or ZIP code for affordable and market-rate rentals, including accessible units, and landlords can list properties for free.
5. Apartments.com
Best for: a large raw inventory of listings, if you want to cast a wide net.
Apartments.com is one of the biggest general apartment websites in the country, with thousands of Denver rentals listed alongside its nationwide database. Listings show starting rents by bedroom count, amenity tags, and current specials, with filters for price, beds and baths, home type and move-in date plus a map view. The tradeoff for that scale is depth — you get unit-level marketing details, but not the kind of structured, comparable building data a Denver-specific directory can offer.
6. Zillow
Best for: renters already using Zillow for buying/selling research.
Of all the Denver apartment websites on this list, Zillow is probably the most familiar name — its rental listings sit alongside its well-known home-sale and Zestimate tools. It’s convenient if you’re already comparing renting against buying, though its Denver-specific building detail is thinner than a dedicated local resource.
Methodology note: this list of Denver apartment websites reflects how much Denver-specific, building-level detail each resource makes available to renters directly, and how easily that information can be used without contacting an agent first. It will be revisited periodically as these services change.
