How to Become a Home Inspector in Colorado: Step-by-Step Guide
Becoming a home inspector in Colorado involves learning the trade, meeting any recommended qualifications, and setting up your business. Unlike many states, Colorado doesn’t impose strict licensing, but aspiring inspectors should still pursue education and certifications to build credibility. This guide will walk you through everything from state regulations to starting your own inspection business, with clear steps and resources for each part of the journey.
1. Licensing Requirements and State Regulations
Colorado does not require a state license to work as a home inspector. In fact, home inspectors are not regulated by any state agency in Colorado . Legislative efforts to introduce licensing have failed – for example, a 2017 bill to require inspector licensing was narrowly defeated , and a 2019 state “sunrise review” likewise recommended against regulating home inspectors . As of 2025, no state board or exam governs general home inspectors in Colorado.
State regulations: With no licensing law, there is no state-mandated training or exam that you must complete for general home inspections. Inspectors are free to practice as long as they operate within general business laws and ethical standards. However, you are still subject to consumer protection laws (for example, against fraud or negligence) even without a license. It’s wise to adhere to industry Standards of Practice (such as InterNACHI or ASHI standards) to ensure your inspections meet professional benchmarks, since these can serve as a guideline for what is expected in an inspection.
Local requirements: Keep in mind that some local jurisdictions in Colorado have their own rules for specific types of inspections. For instance, Denver now requires an inspection by a registered inspector as part of its rental licensing program . (Denver began phasing in this requirement in 2022 for residential rental properties.) Similarly, the City of Lakewood stipulates that short-term rental properties be inspected by an approved inspector – InterNACHI-certified inspectors are explicitly accepted for this purpose . If you plan to do specialized inspections (like rental housing code compliance in certain cities), be sure to check city ordinances for any registration or certification you might need.
Specialized inspection regulations: While general home inspections are unregulated, Colorado does license certain related activities. Notably, as of July 2022, radon measurement professionals must be state licensed . If you intend to offer radon testing, you’ll need to obtain the Colorado radon license through the Department of Regulatory Agencies (DORA). Other ancillary services may have their own requirements as well – for example, wood-destroying organism (termite) inspections might require a pest control license if you are performing formal termite/pest reports. Always check the rules for any specialized inspection service you plan to provide.
Governing bodies: In the absence of state oversight, there is no Colorado home inspection licensing board. If future legislation were enacted, it would likely fall under DORA (the Colorado Department of Regulatory Agencies), which oversees many professions. For now, industry associations effectively set quality standards. Many Colorado inspectors voluntarily join professional organizations (like InterNACHI or ASHI) which require adherence to codes of ethics and standards of practice. These associations fill the gap by providing guidelines and a form of credentialing, helping consumers identify qualified inspectors. (The Colorado Association of REALTORS® also advises consumers to vet inspectors’ qualifications since the state doesn’t license them .)
2. Education and Training Programs

While Colorado law doesn’t mandate formal education, proper training is essential for success. To perform competent inspections (and to attain certifications that clients recognize), you should complete a home inspector training program. Fortunately, there are several reputable options in Colorado, including both online and in-person courses. Here are some accredited schools and programs that meet industry standards:
-
InterNACHI School (International Association of Certified Home Inspectors): InterNACHI, based in Boulder, offers a tuition-free online Home Inspector Certificate Program for its members . This comprehensive program is accredited and covers all aspects of residential inspections. Training modules, the InterNACHI certification exam, and ongoing continuing education are free with membership . InterNACHI’s curriculum is very accessible – you can take courses online at your own pace, and they cover Colorado-specific topics as well. They also provide unique hands-on training at the House of Horrors, a full-size model house in Boulder with 1,000+ built-in defects for students to find . InterNACHI is a popular choice in Colorado because membership not only gives you education but also a pathway to Certified Professional Inspector (CPI) certification (more on that in the Certification section).
-
American Home Inspectors Training (AHIT): AHIT is a well-known training provider that offers online courses and live classes. In Colorado, AHIT’s program is often recommended, and it typically includes around 120 hours of training covering all the major home systems. For example, Aims Community College in Greeley partners with AHIT to offer a Colorado Home Inspector training course through their continuing education department . This course is designed for beginners and teaches you everything from the ground up – no construction experience required. By the end of the program, students are prepared to take the National Home Inspector Exam (NHIE) and even earn certifications in specialties like radon or mold inspection . AHIT’s training mixes online learning with optional in-field practical sessions. They often host multi-day hands-on labs where you can practice inspecting actual homes under an instructor’s guidance. The AHIT courseware is industry-recognized, and completing it provides a certificate that will be useful when seeking employment or clients.
-
Inspection Certification Associates (ICA): ICA offers an online home inspection course that is approved nationwide (with optional add-ons for specialized training). Their self-paced program teaches the technical knowledge and best practices needed to perform inspections in Colorado . One advantage of ICA is that their packages often include extras: for instance, free report-writing software, and bonus courses on mold, radon, thermal imaging, and more . Upon finishing ICA’s course, you receive a certification from ICA and are ready to start your own inspection business or join a company . ICA also periodically runs live field training classes in Colorado – e.g. a two-day hands-on training in Lakewood, CO, where students practice on real homes under instructor supervision . These in-person sessions can complement the online coursework and help you gain practical experience. ICA’s online content is accessible 24/7 and is known for covering not just how to inspect, but also business and marketing topics.
-
Other Training Options: There are additional schools and resources you may consider. Kaplan (KapRE) used to offer home inspection licensing courses and may still have online study packages for Colorado. Professional Home Inspection Institute (PHII) provides an online certification course as well – their program is advertised as meeting “all Colorado requirements” (given there are none, it focuses on aligning with national standards) and includes interactive content and support. PHII and similar programs typically allow you to study at your own pace and take a final exam to earn a completion certificate. Additionally, some community colleges and technical institutes in Colorado offer home inspection training as part of their continuing education catalogs (often these are in partnership with providers like AHIT or ICA). When choosing a program, make sure it covers the breadth of topics (structure, electrical, plumbing, HVAC, roofing, exteriors, interiors, etc.) and ideally prepares you for the NHIE – even though Colorado doesn’t require the NHIE, that exam’s content is a good benchmark for a thorough education.
Tip: Look for courses that are accredited or approved by national inspector organizations. InterNACHI’s school is accredited by the U.S. Department of Education , which speaks to its quality. Many courses (like AHIT and ICA) align with the exam and certification standards of associations like ASHI or InterNACHI. Also consider how you learn best – if you want hands-on practice, opt for programs that include live training or field events in Colorado. If you need flexibility, an online self-paced course might be better. Continuing education is important too; even after initial training, plan to keep learning. (While Colorado doesn’t mandate continuing education, InterNACHI requires its certified inspectors to complete 24 hours of CE annually , and ASHI also has annual CE requirements for members.)
3. Certification Options
Even though Colorado doesn’t license inspectors, earning a professional certification is highly recommended. Certifications demonstrate your knowledge and credibility to clients and real estate agents. In fact, industry experts note that while not mandatory, certifications “can boost your credibility and marketability” as a home inspector . The two most recognized certifications in Colorado (and nationally) are through InterNACHI and ASHI, but there are a few others to consider as well. Here are the main certification options and designations:
-
InterNACHI Certified Professional Inspector (CPI) – This is one of the most popular credentials in Colorado. To become an InterNACHI CPI, you must join InterNACHI and complete their certification requirements. InterNACHI’s requirements include passing an online inspector exam, completing a series of training courses, passing ethics and standards of practice quizzes, and submitting mock inspection reports. The good news is InterNACHI provides all the required training and exams online for free to members . Once you complete the process, you earn the Certified Professional Inspector designation. CPI is a well-known mark; it shows you have met InterNACHI’s standards and abide by their Code of Ethics. InterNACHI certification is voluntary (since the state doesn’t require it), but it’s often expected by clients. Additionally, InterNACHI members in Colorado get access to an InterNACHI photo ID, a certification logo to use in marketing, and ongoing support. Many Colorado inspectors go this route because InterNACHI membership comes with not only the CPI certification but also resources to help in starting the business (education, marketing, documents, etc.). Bottom line: InterNACHI’s CPI is an excellent baseline certification to attain – it assures the public that you have completed a rigorous training program and examination.
-
ASHI Certification (American Society of Home Inspectors): ASHI is the oldest home inspector association in the U.S., and their certification is highly respected. ASHI Certified Inspector status is a bit more involved to achieve initially: all new ASHI members start as Associates and then work their way up. To become ASHI Certified, an inspector must pass the National Home Inspector Examination (NHIE) and complete at least 250 paid inspections that are verified by ASHI . ASHI also requires passing their own Standards of Practice and Code of Ethics exam (usually a shorter test). In practice, many inspectors join ASHI early on – you can join as an Associate before you have 250 inspections – and meanwhile take training and pass the NHIE. Once you reach the experience threshold, you can move up to ASHI Certified Inspector (ACI) status. ASHI’s certification process is robust: it effectively combines education, exam, and experience. While working toward full certification, ASHI members can use titles like “ASHI Associate” or “Inspector-in-Training”. Achieving ACI status is a strong credential that tells clients you meet a national standard. In Colorado, ASHI’s Rocky Mountain Chapter provides support to members (including peer review of reports and ride-along opportunities that can count toward the 250 inspections). Even if you pursue InterNACHI’s certification, you might consider also joining ASHI to tap into its network and reputation. Some inspectors maintain both InterNACHI and ASHI certifications for maximum credibility.
-
National Home Inspector Examination (NHIE): The NHIE is the national exam that many states use for licensing. Colorado doesn’t require it, but it’s still a respected credential to have on your resume. You can choose to take the NHIE voluntarily to test your knowledge. It’s a 4-hour, 200-question proctored exam that covers all aspects of home inspection practice . Each attempt costs about $225 . Passing the NHIE can fulfill the exam requirement for ASHI certification and is viewed favorably by some insurance companies and clients. If you’re planning to work in or near states that do require licensing (for example, Kansas or Texas) or you want to be prepared in case Colorado enacts licensing in the future, taking the NHIE is a smart move. Upon passing, you’ll receive a score report and you can say you’ve “passed the National Home Inspector Exam,” which is a confidence booster for clients even if it’s not mandated. Keep in mind that you’d need to study for it (even experienced inspectors often use exam prep courses because of the exam’s breadth). Many training programs, like those mentioned above, include NHIE prep.
-
Other Certifications and Designations: Beyond the basic inspector certifications, there are additional credentials you might pursue:
- Specialty Certifications: If you plan to offer services like radon testing, mold inspection, or sewer scope inspections, seek the relevant certifications. For example, you can become certified by the National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB) for radon testing (and remember Colorado now requires a state license for radon measurement). InterNACHI offers a Certified Radon Tester course and certification as well. For mold, there are certifications like Certified Residential Mold Inspector. These specialized certs are often voluntary but can be selling points to clients.
- Certified Master Inspector (CMI): This is a prestigious professional designation awarded by the Master Inspector Certification Board (associated with InterNACHI, but a separate entity). To qualify, you need to have been in business for at least three years and completed 1,000 inspections or hours of education combined, among other criteria. CMI is an advanced title that some veteran Colorado inspectors hold. It’s something to keep on your radar for the future; it can set you apart once you have substantial experience.
- Other Associations: There are smaller organizations like the National Society of Home Inspectors (NSHI) and the now-defunct NAHI (National Association of Home Inspectors). NSHI is another certifying body (the Colorado Association of REALTORS® has mentioned NSHI as a resource ). However, NSHI is not as widely recognized as InterNACHI or ASHI. Since NAHI merged into ASHI, essentially ASHI and InterNACHI are the two pillars of the industry now. You might also come across state-specific groups or certifications, but in Colorado, no state agency certificate exists due to the lack of regulation.
In summary, while you could legally inspect homes in Colorado without any certification, doing so is not advisable. Getting certified through InterNACHI, ASHI, or both will greatly enhance your professional image. It shows you’ve met industry standards for knowledge and performance. Clients, real estate agents, and insurance providers will trust you more if you carry well-known credentials. Plus, membership in these organizations often provides ongoing education – ensuring you stay current with building practices and inspection techniques. Many Colorado inspectors choose to become InterNACHI Certified and pass the NHIE (meeting ASHI requirements), covering all bases. Evaluate which path suits your career goals and complete those certification steps as one of your early milestones.
4. Costs Involved
Starting a home inspection career in Colorado entails several up-front and ongoing expenses. It’s important to budget for education, exams, business startup costs, and tools. Below is a breakdown of typical costs:
-
Training and Education Fees: These can range from free (with membership) to a few thousand dollars, depending on the route you choose. For instance, if you go with InterNACHI, the online training and certification program itself costs nothing beyond the membership dues (InterNACHI membership is 499 per year , which gives you unlimited access to all courses). Other training options like AHIT or ICA have set course fees – an online course might cost around 800, while a premium package with classroom training can cost 2,000. As an example, ICA’s online course is roughly in that range (their bundle including an English and Spanish course is about 2,495. The good news is these are usually one-time costs to get started. You should also factor in any optional courses (like a radon class or a termite inspection course) if they’re not included in your main program. Some programs include those extras in their price. Always confirm what a course package includes (textbooks, field training, etc.) so you know what you might need to purchase separately.
-
Exam Fees: If you plan to take the National Home Inspector Examination, the fee is about **80–50–$200, though some training packages include exam prep.
-
Certification and Membership Fees: While not mandatory, you will likely invest in association memberships for the benefits and credibility. InterNACHI’s membership is 499/year . This fee covers all training, certification, and even a suite of business tools, which is a great value for most inspectors. ASHI’s membership is on a yearly basis – there’s a 449 per year** in dues . (ASHI also offers a monthly payment option around 499, ASHI 500 a year for each association membership you maintain. These fees are typically considered business expenses (tax-deductible). Aside from association dues, certification-specific fees are minimal – InterNACHI charges no extra for the CPI designation beyond membership, and ASHI’s certification process doesn’t have an extra charge beyond membership and exam costs. If you pursue a Certified Master Inspector (CMI) later, note that the one-time fee for that title is around $2,500 (as it is meant for experienced inspectors). Specialty certifications might have costs too (e.g., a radon license exam fee or NRPP certification fee of a few hundred dollars).
-
Business Formation and Licensing Fees: Setting up your business in Colorado is relatively inexpensive. If you choose to form an LLC (Limited Liability Company) – which many inspectors do for liability protection – the Colorado Secretary of State charges a **1 under a relief program, but as of 2024 it’s back to 20. Colorado does not require a general state business license or permit to operate a home inspection business, so you won’t have a state licensing fee for the business itself . Do check if your city or county requires a local business license – some municipalities have an annual business license tax or fee (often nominal, like 50/year, but it varies). Additionally, if you will collect sales tax on any products (most inspectors don’t, since a service isn’t taxed in CO), you’d need a sales tax license (usually free or low cost through the Department of Revenue). Professional licenses: As mentioned earlier, if you offer radon testing, you’ll need to obtain the radon license through DORA – the application fee for that license (for measurement professional) is roughly 100 for exams/registration. These are optional based on services. For general home inspection, your main business-related fees will be the entity registration and any necessary local permits.
-
Insurance Costs: Insurance is one of the most significant ongoing expenses for home inspectors. It’s strongly recommended (and often effectively required by client expectations or association membership) that you carry general liability and errors & omissions insurance. General Liability (GL) insurance covers bodily injury or property damage that might occur during an inspection (for example, you accidentally break a homeowner ’s light fixture or you step through an attic ceiling). Errors & Omissions (E&O) insurance covers you against claims that you missed a defect or made an error in your inspection report. In Colorado, while not mandated by law, many brokers and customers will only work with insured inspectors, and InterNACHI/ASHI ethics pretty much demand it. Plan for roughly **50 per month for a 50–75 per month for E&O coverage** for a single-inspector firm . Actual premiums depend on your coverage limits and deductible. Some insurers offer combined GL/E&O packages for home inspectors. By one estimate, *general liability can be about 40/month and E&O about 1,200/year total for comprehensive coverage. It could be higher in your first year or if you opt for higher limits (e.g., $2M coverage). You might lower costs by choosing a higher deductible or limiting certain coverages. Also note, if you drive a personal vehicle for business, ensure your auto insurance covers business use or get a commercial rider. Some associations have negotiated discounts with insurance providers (InterNACHI members, for example, get special rates on inspector insurance). Be sure to obtain insurance before you start inspecting for pay, and include the insurance line in your ongoing budget.
-
Tools and Equipment: Acquiring a basic set of inspection tools will be another upfront cost. The nice thing is home inspection doesn’t require extremely expensive machinery, but you will need a variety of tools and gadgets to do a thorough job. Key items include: a good quality ladder (possibly both a collapsible 12-foot ladder for interiors and a larger extension ladder for roofs), flashlights (high lumen, and backups), an electrical tester (for outlets and GFCIs), a voltage detector pen, infrared thermometer or thermal camera, a moisture meter, an IR camera (optional but increasingly common to scan for temperature anomalies), combustible gas detector, carbon monoxide analyzer, and basic hand tools (screwdrivers, inspection mirror, tape measure, level, etc.). You’ll also want personal protective equipment: good boots, coveralls/old clothes for crawlspaces, gloves, dust mask or respirator, safety glasses, and maybe a hard hat for crawlspaces. If you perform sewer scope inspections, that camera equipment is a bigger cost (often 1,000+, though you could start with charcoal canisters (1,000**. For example, a quality 4-in-1 gas detector might be 100, a thermal camera 200. You can start lean (maybe $500 total for the basics) and upgrade tools as you go. Some training programs provide certain tools or offer student discounts on tool kits. InterNACHI members often get discounts from tool manufacturers as well . Remember, these are tax-deductible expenses as they are necessary for your business. It pays not to skimp on key tools like your ladder and safety equipment – your personal safety and the quality of your inspection rely on them.
-
Reporting Software: Professional home inspection software is essential for creating reports to deliver to clients. There are many options (HomeGauge, Spectora, Home Inspector Pro, EZ Home Inspection, etc.), and costs vary. Some software is a one-time purchase (e.g., 50–600** for software for the first year (could be less if you take advantage of trials or free versions). Also budget for a decent tablet or laptop if you don’t already have one, since you’ll need it on inspections to input your findings.
-
Other Business Costs: Don’t forget miscellaneous costs of running a business. This includes marketing expenses (like designing a logo, printing business cards, creating a website). Many new inspectors spend on a website domain and hosting (200/year, unless you use a free platform), and on marketing materials (business cards, brochures for real estate offices – maybe
