Top 10 Origin ZIP Codes for Castle Pines Relocating Homebuyers (Last 4 Years)

Over the past four years, Castle Pines (ZIP 80108) has seen notable migration from both local and out-of-state homebuyers. While roughly 68% of Castle Pines buyers come from within the Denver metro area, about one-third are relocating from other cities and states. Real estate migration data (primarily from Redfin and U.S. Census estimates) highlight the following top 10 origin ZIP codes (by city/metro) for people moving into Castle Pines, Colorado:

1. 90001 – Los Angeles, CA: Los Angeles is the #1 origin for Castle Pines newcomers. Redfin identifies the L.A. metro as the top source of homebuyer interest in Castle Pines, with Los Angeles homebuyers leading all other metro origins. In a recent quarter, this translated to a net inflow of about 589 Castle Pines-bound searches from Los Angeles – roughly 27% of all out-of-metro interest. Many Californians are drawn by Colorado’s relatively affordable home prices and high quality of life compared to Southern California’s expensive housing market. This trend accelerated post-2020, as major cities like Los Angeles saw population losses and residents looked for opportunities in places like Denver’s suburbs.

2. 80920 – Colorado Springs, CO: Colorado Springs ranks #2 among origin areas. Significant in-state migration comes from the Colorado Springs area (ZIP codes 809xx), located about an hour south of Castle Pines. Redfin data shows a net inflow of roughly 328 home searchers from the Colorado Springs metro to Castle Pines in early 2025. This suggests many Front Range residents are moving north – potentially for jobs in the Denver area or to enjoy Castle Pines’ family-friendly suburban environment and schools. Proximity and familiarity play a role, as intra-Colorado moves remain common (Colorado Springs is a large city whose residents often relocate within the state for career or lifestyle reasons).

3. 77024 – Houston, TX: Houston is the #3 origin for Castle Pines movers. The Houston metro (ZIP 770xx) is a major out-of-state feeder to Colorado. Redfin’s migration tracker recorded about 249 net homebuyers from Houston searching in Castle Pines during a recent period. This reflects a broader Texas-to-Colorado migration pattern – Texas was the second-largest source of new Colorado residents in 2022 (over 25,000 Texans moved to CO that year). Many Houston families are relocating to Colorado for its milder climate, outdoor recreation, and booming job market, despite Colorado’s somewhat higher cost of living. Houston’s inclusion (along with Dallas and Austin) underscores Colorado’s appeal to those leaving Texas.

4. 94102 – San Francisco, CA: The San Francisco Bay Area is another top source, ranking #4. Redfin data show around 214 net searches from the San Francisco metro (ZIP 94xxx) into Castle Pines homes. High-cost California markets like San Francisco have consistently sent buyers to Colorado, as they seek more house for the money. In fact, Denver-area home prices, while elevated, are still “significantly more affordable than San Francisco”. Bay Area transplants are attracted by Colorado’s relative affordability and quality of life – selling a pricey California home often allows them to upgrade to a larger home in Castle Pines. The lifestyle change (from crowded Bay Area to spacious, scenic Colorado) is another draw for these movers.

5. 81004 – Pueblo, CO: Pueblo (southern Colorado) appears as the #5 origin. Approximately 190 net home searchers came from the Pueblo metro (ZIP 810xx) into Castle Pines, per Redfin’s recent data. This indicates that some residents of Pueblo – a more affordable Colorado city – are moving north to the Denver suburbs. They may be pursuing higher-paying jobs or seeking the amenities of Douglas County (one of Colorado’s fastest-growing counties). The pattern suggests equity migration: homeowners in lower-cost areas like Pueblo can sell their homes and relocate to upscale communities such as Castle Pines. The draw of better schools and newer housing in Castle Pines may also be factors for families coming from Pueblo.

6. 10001 – New York, NY: New York City is the #6 source of Castle Pines newcomers. Even though it’s across the country, the NYC metro (ZIP 100xx and surrounding) contributed a net inflow of about 183 Castle Pines home searches in a recent quarter. This mirrors pandemic-era migration trends – New York saw residents leave after 2020, and some headed for Colorado’s Front Range. In 2022 alone, 8,526 people moved from New York to Colorado. Many of these buyers are likely drawn by Colorado’s lower taxes, spacious suburban homes, and outdoor lifestyle. Remote work has made such long-distance moves easier, enabling NYC professionals to settle in places like Castle Pines while retaining East Coast jobs. The inflow from New York underscores the nationwide reach of Colorado’s appeal.

7. 60610 – Chicago, IL: Chicago ranks #7 among origin locations for Castle Pines. The greater Chicago area (ZIP 606xx and suburbs) accounted for roughly 161 net searches for Castle Pines homes in Redfin’s data. Illinois has been a notable contributor to Colorado’s population growth – about 9,281 Illinoisans moved to Colorado in 2022 – and Chicago’s share in Castle Pines migration reflects that trend. Drivers include corporate relocations and lifestyle preferences: Chicagoans might trade Midwest humidity (and tollways!) for Colorado’s sunshine and mountains. The robust Denver job market and desire for more outdoor recreation can entice families from Chicagoland to communities like Castle Pines. This Midwestern migration adds to the diversity of newcomers in the area.

8. 75204 – Dallas, TX: Dallas–Fort Worth is #8 on the list of origins. Redfin’s tracker shows about 144 net homebuyer inquiries from the Dallas metro (ZIP 75xxx) into Castle Pines. Along with Houston and Austin, this cements Texas as a key feeder region for Colorado. In fact, Texas overall was behind only California in sending new residents to Colorado (over 25,000 Texans relocated to CO in 2022). Many Dallas-area families cite Colorado’s cooler climate, mountain lifestyle, and tech jobs as reasons for moving. Castle Pines, as part of Denver’s affluent southern suburbs, is appealing for those seeking larger homes and open space. The continued Dallas-to-Colorado flow underscores how Colorado’s economic and lifestyle advantages attract movers from even relatively prosperous Sun Belt cities.

9. 78759 – Austin, TX: Austin appears at #9 among top origin ZIPs, albeit with a smaller share. Redfin reports a net inflow of roughly 43 Austin-area homebuyers into Castle Pines in the recent period. Austin’s representation – alongside Houston and Dallas – highlights the Austin-to-Colorado tech corridor: both Austin and Denver are tech hubs, and some talent relocates between them. Austinites moving to Castle Pines may be chasing new job opportunities in Denver’s tech scene or simply a change of scenery. Additionally, Colorado’s less humid climate and outdoor recreation can be attractive after Central Texas’s hot summers. Although the volume is modest, Austin’s inclusion shows that even America’s booming tech cities are source regions for Castle Pines’ growth.

10. 19103 – Philadelphia, PA: Philadelphia (including South Jersey suburbs) rounds out the top 10. The Philly metro (ZIP 191xx) contributed an estimated 31 net home searchers interested in Castle Pines. This smaller inflow still underscores that Castle Pines draws newcomers from coast to coast. Some Philadelphia-area families and retirees have been relocating westward, drawn by Colorado’s strong economy and lifestyle. Whether it’s for jobs in the aerospace/tech industries or simply a mountain-state retirement, a trickle of East Coast buyers are choosing communities like Castle Pines. This illustrates the broad nationwide appeal of Colorado: even the Mid-Atlantic region sends a contingent of homebuyers to the Denver suburbs each year, adding to Castle Pines’ growth and demographic mix.

Each ZIP code above is paired with its city and state, representing a ranked origin of Castle Pines homebuyers from 2019 to 2023. These trends are supported by real estate data from Redfin’s migration analysis and U.S. Census-based migration figures. In summary, California and Texas dominate the inbound migration (with multiple cities each in the top 10), followed by other Colorado cities and a few major metros in the Northeast/Midwest. The common thread is that many newcomers are coming from higher-cost or larger urban areas and are attracted to Castle Pines for its affordable upscale housing, jobs, schools, and quality of life. This migration pattern has fueled Castle Pines’ rapid growth (33% population increase since 2020) and solidified its status as a sought-after destination for relocators from across the country.
