Castle Rock CO rent increase 2026 Castle Rock, Colorado has no local rent control in 2026. Castle Rock IS the Douglas County seat — the courthouse (Douglas County Combined Court, 4000 Justice Way, Castle Rock CO 80109) is located within Castle Rock itself. Castle Rock landlords file evictions in their own city, unlike Parker (~22 miles away), Highlands Ranch (~12–18 miles), and Lone Tree (~10–14 miles), all of which travel to Castle Rock to file. As a municipality, Castle Rock could enact rent control under Colorado HB 21-1117 (2021) but has not done so. Population ~82,000 and growing rapidly (from ~20,000 in 2000 — 310% growth in 24 years). Castle Rock Adventist Hospital / AdventHealth (~200 beds; ~1,200 employees). Douglas County Government (county seat). DCSD schools (Castle View HS, Douglas County HS, Legend HS). I-25 midpoint between Denver (30 miles) and Colorado Springs (60 miles). New construction dominates. 10-day pay-or-quit (HB 21-1121). 60-day deposit return; 3× willful penalty.

Colorado HB 21-1117 and Castle Rock: no rent control, but not immune

Colorado HB 21-1117 (April 2021) repealed the 1994 statewide rent control preemption, restoring authority to enact rent stabilization to Colorado municipalities. Castle Rock is an incorporated municipality (technically a “town” under Colorado law, though approaching city-level population) with a governing board (Town Council) authorized to enact local ordinances.

This means Castle Rock is legally capable of enacting rent control — it simply has not done so. The Castle Rock Town Council has not introduced any rent stabilization or rent control ordinance as of 2026. Castle Rock’s rapid new-construction growth and politically moderate-to-conservative town council make rent control unlikely in the near term, but it is not legally impossible the way it is for Highlands Ranch.

The bottom line: Castle Rock landlords operate under Colorado state law only — no cap, no formula, no notice requirement for the amount of increase (only for the timing of notice). Any amount increase is permitted at lease expiration.

Castle Rock is the Douglas County seat: a key courthouse advantage

For landlords in Castle Rock specifically, the county-seat location provides a meaningful practical advantage: the Douglas County Combined Court (4000 Justice Way, Castle Rock CO 80109) is within Castle Rock’s own city limits.

Compare the travel burden for other Douglas County landlords:

• Parker: approximately 22 miles north of Castle Rock (Hess Rd / Lincoln Ave area to Castle Rock via I-25 and Founders Pkwy).
• Highlands Ranch: 12–18 miles north of Castle Rock depending on property location within Highlands Ranch.
• Lone Tree: approximately 10–14 miles north of Castle Rock via I-25.
• Larkspur: approximately 9 miles south of Castle Rock (smaller Douglas County community).
• Castle Pines: approximately 4 miles north of Castle Rock.

Every Douglas County FED case — evictions from Parker to Highlands Ranch to Lone Tree — is filed at Castle Rock’s courthouse. Castle Rock landlords are the only Douglas County landlords who walk to the courthouse from their own community.

Major employers and rental demand in Castle Rock CO

Castle Rock Adventist Hospital / AdventHealth Castle Rock

AdventHealth Castle Rock (formerly Centura Health Castle Rock Adventist Hospital; 2350 Meadows Blvd, Castle Rock CO 80109) is the primary acute care hospital serving the Castle Rock and southern Douglas County communities. Operating approximately 200 licensed beds, the facility provides emergency, surgical, cardiac, maternity, and oncology services. AdventHealth (the Seventh-day Adventist Health system) employs approximately 1,200+ people at this campus including physicians, nurses, therapists, and administrative staff. Healthcare workers here earn $45,000–$250,000+ and represent a stable, locally-rooted base of rental demand in northwest Castle Rock near Meadows Blvd.

Douglas County Government — county seat employment

As the Douglas County seat, Castle Rock hosts the full range of county government operations: the Combined Court (judges, clerks, public defenders, district attorneys), Douglas County Sheriff headquarters, Douglas County Assessor, Douglas County Clerk and Recorder, Douglas County Human Services, and various other administrative departments. Douglas County employs approximately 2,000+ people in Castle Rock, making county government one of the top single employers in the city. Many county employees choose to live in Castle Rock to minimize commutes to county offices and the courthouse.

Douglas County School District RE-1 — staff employment

DCSD is Douglas County’s largest employer countywide, with approximately 5,500+ district employees. Castle Rock-area schools include Castle View HS, Douglas County HS, Legend HS, and Rhyolite Elementary, as well as numerous other elementary and middle schools. Teachers and support staff employed at Castle Rock schools who do not own locally often rent within Castle Rock, contributing to baseline demand for mid-range apartments and townhomes.

Denver Tech Center commuters and I-25 access

Castle Rock’s most important economic driver for rental demand is its position on I-25: approximately 30 miles south of the Denver Tech Center (DTC) at Arapahoe/I-25, approximately 35 miles south of downtown Denver, and approximately 60 miles north of downtown Colorado Springs. This I-25 location enables a commuter lifestyle: workers at Denver Tech Center, Centennial, south Denver, and even Colorado Springs employers choose Castle Rock for more affordable SFR rentals, larger properties, and DCSD school access while accepting the 30–45 minute I-25 commute. Castle Rock is particularly attractive for dual-income households where one partner works north (Denver/DTC) and one works south (Colorado Springs area).

Castle Rock Premium Outlets

The Castle Rock Premium Outlets (5050 Factory Shops Blvd, Castle Rock CO 80108) is one of the largest outlet mall complexes in Colorado, anchoring a significant retail employment cluster along I-25 at the Meadows Pkwy interchange. While retail wages are lower than the tech/healthcare employer base, the outlet complex employs 500–1,000+ workers who represent demand for Castle Rock’s more affordable apartment inventory (older stock; smaller units) in the range of 1BR $1,100–$1,500.

Eviction process in Castle Rock CO: step-by-step

Step 1: Serve 10-Day Demand for Payment or Possession

CRS §13-40-104(d) (as amended by HB 21-1121): for non-payment of rent, serve written notice stating the exact amount of rent owed and demanding payment or possession within 10 days. If the tenant pays the full stated amount within 10 days, the landlord cannot file for eviction. Include only past-due base rent in the notice — not late fees or utilities — as overstatement of the amount owed can void the notice.

Step 2: File FED complaint at Douglas County Combined Court

Douglas County Combined Court, 4000 Justice Way, Castle Rock CO 80109. Castle Rock is the Douglas County seat: the courthouse is in Castle Rock. No travel to a separate county seat required. Filing fee approximately $85–$175.

Step 3: Douglas County Sheriff serves summons; hearing scheduled

The Douglas County Sheriff serves the summons on the tenant. Hearing typically scheduled within 7–14 business days.

Step 4: Writ of Restitution and lockout

Upon judgment for the landlord, the court issues a Writ of Restitution. The Douglas County Sheriff posts the 24-hour notice and executes the lockout. Total uncontested timeline from 10-day notice service to lockout: approximately 4–6 weeks.

10 common Castle Rock landlord mistakes under Colorado CRS

1. Using the old 3-day eviction notice. Colorado HB 21-1121 (2021) extended the non-payment notice to 10 days. A 3-day notice served in 2026 is legally defective. The FED case will be dismissed. Must re-serve a proper 10-day notice and restart the timeline.
2. Confusing Castle Rock (Douglas County seat) with other cities that must travel to Castle Rock to file. Castle Rock landlords file IN Castle Rock. This is not obvious to new landlords who hear “go to the Castle Rock courthouse” and assume that means they must be outside Castle Rock. You are already there — the courthouse is at 4000 Justice Way within your own city.
3. Missing the 30-day deposit return deadline after written demand. If the tenant sends a written demand for return of the security deposit, the 60-day deadline collapses to 30 days. Use 30 days as the internal standard. On a Castle Rock new-construction SFR deposit of $3,800, willful wrongful withholding = $11,400 + attorney fees.
4. Not itemizing the deposit deduction statement. CRS §38-12-103(2): every deduction must be itemized by item and dollar amount. A vague statement (“cleaning and repairs: $450”) may not satisfy the statute. Document each item separately.
5. Entering the unit without 24-hour written advance notice. CRS §38-12-1102 (HB 19-1118): 24 hours’ advance written notice required. Text message sent 20 hours before entry is legally borderline. Written email or hand-delivered notice at least 24 hours prior is the safe standard.
6. Self-help eviction: changing locks, removing belongings, shutting off utilities. CRS §38-12-510: $5,000 punitive damages + actual damages + attorney fees. In a Castle Rock FED, the timeline from filing to lockout with sheriff service is 4–6 weeks — faster than many markets. The shortcut is not worth the penalty.
7. Underpricing based on older Castle Rock rent comparables. Castle Rock has grown ~310% since 2000; the newer construction stock (2015–2024) commands premiums significantly above older apartments built before 2010. Anchoring rent to old data undervalues new construction inventory.
8. Not documenting DCSD school zone in rental listings. Castle View HS and Legend HS feeder zone properties command $150–$300/month more than equivalent units outside premium DCSD school zones. Listing without school zone information leaves money on the table for landlords in high-rated feeder areas.
9. Expecting I-25 congestion not to affect vacancy. I-25 between Castle Rock and Denver can be extremely congested during peak commute hours. Units marketed to DTC commuters are most attractive when they are close to Castle Rock’s northern I-25 entrance (Founder’s Pkwy / Meadows Pkwy interchanges). Units requiring a drive across Castle Rock to reach I-25 are less desirable for commuters.
10. Not having a lease termination clause for new-construction delivery delays. New construction is common in Castle Rock, and delays in developer project completion can create scenarios where a landlord has an incoming tenant but the property is not ready. Clear contractual provisions for delivery delay scenarios reduce disputes and potential tenant damage claims.
