Appraisal licensing is not one credential. Appraisers hold different levels of certification, and each level defines what an appraiser is legally permitted to value. For commercial property, the distinction is not a formality — it determines whether a report is valid at all.
A Certified Residential Appraiser is authorized to appraise one-to-four unit residential properties without regard to value or complexity, and certain smaller non-residential assignments. That scope covers houses, condominiums, and small residential buildings. It does not extend to commercial property.
A Certified General Appraiser (CGA) is authorized to appraise all types of real property — commercial, industrial, multifamily, land, and special-purpose properties — without limitation on value or complexity. Office buildings, retail centers, warehouses, apartment complexes of five units or more, hotels, and development land all fall under the CGA scope.
Commercial valuation demands analysis that residential work does not. Income capitalization, discounted cash flow, lease analysis, and highest-and-best-use studies are core to commercial assignments and are not part of residential practice. The Certified General credential exists because these properties require a deeper analytical skill set. A residential license does not authorize this work, and no amount of experience substitutes for the correct credential.
Using an appraiser without the proper certification is not a technicality that gets overlooked. A commercial appraisal performed by an appraiser who lacks the Certified General credential can be rejected outright by a lender. For federally related transactions, credentialing requirements are enforced under FIRREA, and a report from an under-credentialed appraiser can trigger a review, a delay, or a demand for a new appraisal — at the borrower's expense. In litigation or estate matters, opposing counsel or a taxing authority can challenge the appraiser's qualifications and undermine the report's weight.
The Certified General credential is the highest level of appraisal certification. Earning it requires substantial specialized education in appraisal principles, income capitalization, statistics, and USPAP — capped by a bachelor's degree or its equivalent. It requires thousands of hours of supervised experience, with a meaningful portion in non-residential work. And it requires passing a national examination specific to general appraisal practice. After certification, CGAs must complete ongoing continuing education, including recurring USPAP updates, to keep the credential active.
Anyone ordering a commercial appraisal can confirm the appraiser's credential through the Appraisal Subcommittee's National Registry at asc.gov. Search by name or license number, verify the state, and confirm the credential level shows Certified General. It takes two minutes and eliminates one category of risk entirely.
At Nationwide Commercial Appraisers, every assignment is completed by a Certified General Appraiser. There is no exception by property type, size, or purpose.
