Step-by-Step: Getting Your Colorado ESA Letter
Determine if You May Qualify
You need a diagnosed or diagnosable mental health condition that substantially limits a major life activity. Common qualifying conditions: anxiety disorders, depression, PTSD, bipolar disorder, OCD, ADHD, schizophrenia, and others. You do not need a prior diagnosis on paper — our clinicians assess your symptoms during the evaluation.
Choose a Colorado-Licensed Provider
Your ESA letter must be signed by a mental health professional licensed in Colorado — an LCSW (Licensed Clinical Social Worker), LPC (Licensed Professional Counselor), psychologist, or psychiatrist. Using an out-of-state provider or an automated online service significantly weakens your letter.
Complete the Clinical Evaluation
Key Step — Determines LegitimacyA legitimate evaluation includes a thorough mental health questionnaire (PHQ-9, GAD-7, or equivalent) plus questions about how your condition affects daily life and how your ESA helps. This can be done entirely online via telehealth. Avoid any service that generates a letter instantly without clinician review.
Clinician Reviews and Issues Letter
A Colorado-licensed clinician reviews your evaluation responses, makes a clinical determination, and writes your personalized ESA letter on official letterhead. This should take 24–48 hours — if a letter is issued instantly, that is a red flag.
Submit to Your Landlord
Email or hand-deliver your ESA letter to your Colorado landlord along with a formal written accommodation request. Keep copies. Your landlord has a reasonable time to respond (typically 10 business days). If denied, see our Colorado Landlord ESA Rights guide.
Who Can Write an ESA Letter in Colorado?
HUD guidance specifies that ESA letters must come from a licensed mental health professional. In Colorado, that means:
