Contact

National Home Inspection Authority serves as a public-facing reference directory for the residential inspection sector across all 50 states. This page covers how to reach the directory's administrative office, what geographic scope the resource addresses, how to structure a message for efficient handling, and what response timelines apply to different inquiry categories. Practitioners, researchers, and service seekers navigating the home inspection profession will find the relevant contact logistics here.

How to reach this office

National Home Inspection Authority operates as a national-scope directory resource within the residential construction and inspection sector. The administrative contact function for this directory handles four distinct inquiry categories:

1. Listing submissions and updates — requests from licensed home inspection professionals or firms to add, modify, or remove directory entries
2. Data corrections — factual corrections to inspector credentials, license numbers, service area descriptions, or affiliated certifications listed in the directory
3. Research and press inquiries — requests from journalists, academic researchers, or industry analysts seeking sector-level data or structural information about the home inspection profession
4. General directory questions — questions about how the directory is organized, what qualifications are reflected, or how the Home Inspection Listings resource is structured

All contact should be directed through the administrative messaging interface associated with this domain. Telephone inquiries are not processed at the directory level. Physical mail to a general address is not a supported contact method for this resource.

Service area covered

This directory addresses the home inspection profession at the national level, spanning all U.S. states and territories where residential property inspection services operate under state-level licensing or certification frameworks. Home inspection licensing requirements differ substantially by jurisdiction — as of the most recent American Society of Home Inspectors (ASHI) tracking data, more than 40 states maintain some form of mandatory licensing or registration for home inspectors, while a smaller subset operate under voluntary certification standards only.

The directory does not restrict listings by state. Inspectors holding credentials from recognized bodies — including ASHI, the International Association of Certified Home Inspectors (InterNACHI), and the National Academy of Building Inspection Engineers (NABIE) — are eligible for directory consideration regardless of the state in which they hold licensure.

Inspection categories covered within the national scope include:

• General residential inspection — whole-home assessments benchmarked against standards such as ASHI Standard of Practice or InterNACHI's Standards of Practice
• Specialty inspections — radon, mold, sewer scope, infrared thermography, and wood-destroying organisms (WDO), each of which may carry distinct licensing requirements under state or EPA frameworks
• New construction phase inspections — foundation, framing, pre-drywall, and final inspections tied to the building permit cycle under International Residential Code (IRC) jurisdiction
• Pre-listing and pre-purchase inspections — transaction-specific inspection types governed by timing conventions in real estate contracts rather than separate licensing tiers

What to include in your message

Incomplete messages create processing delays. The following structured breakdown covers what each inquiry type requires for efficient handling.

Listing submission or update:
- Full legal name and trade name of the inspection firm or sole proprietor
- State(s) of licensure and current license number(s) as issued by the relevant state agency
- Certification body affiliation(s) (ASHI, InterNACHI, NABIE, or equivalent) and membership or certification ID
- Primary service counties or metropolitan areas covered
- Specialty inspection categories offered, if applicable
- Preferred contact URL or phone number for the public-facing listing

Data correction:
- The specific listing or entry in question, identified by inspector or firm name
- The incorrect data field and the documented correct information
- A reference source for the correction (e.g., state licensing board verification URL, certification body member lookup)

Research or press inquiry:
- Institutional affiliation of the requesting party
- Specific data points or directory scope questions being researched
- Publication or project name, if applicable

General directory question:
- A plain-language description of the question, referencing the specific page or section of the directory that prompted it — for example, the Home Inspection Listings page or the purpose and scope reference

Messaging that omits licensing credential details in listing requests will not be processed until that information is supplied. The directory applies a verification standard that cross-references submitted license numbers against publicly accessible state licensing board databases where those databases are available.

Response expectations

Response timelines vary by inquiry category and complexity. The following framework applies:

Listing submissions flagged for additional credential verification — particularly those involving multi-state licensure or specialty inspection categories regulated under federal frameworks such as EPA Section 608 (refrigerant handling) or EPA RRP (Renovation, Repair, and Painting Rule for lead-based paint) — may require up to 14 business days before confirmation.

Incomplete submissions do not enter the active queue. A single follow-up notification is issued when a submission is placed on hold for missing information; if the missing data is not supplied in a timely manner of that notice, the submission is closed and must be resubmitted.

Responses are issued to the email address provided at point of contact. Bulk submission requests from multi-inspector firms or franchise operations covering 10 or more listings should note that designation in the message subject line, as those are routed through a separate batch review process with an extended 15-business-day standard window.
