Commercial and Multifamily Cost Segregation Companies
Compare cost segregation providers by property fit, study scope, evidence, review and total fees. Published by Stratum; no independent ranking.
For a large apartment, office, retail or industrial building, compare the proposed technical team, similar-property experience, site verification and basis reconciliation. A national brand or long menu of incentives does not establish the scope of your particular study.
Publisher disclosure: Stratum provides property studies and is a commercial participant in this market. Provider inclusion is a research shortlist, not a ranking or verified endorsement for every building. Public descriptions do not establish a signed engagement.

Compare the proposed work
Ask each firm to explain how it will inventory shared systems, verify quantities, address tenant improvements and reconcile phases or buildings. Request a redacted report from a comparable property and the credentials of the people assigned to your engagement.

Make the pricing comparison meaningful
Obtain written proposals using the same property records. Identify inspection, study, revisions, examination support, accounting-method work and return preparation separately. Stratum charges $1 per square foot with a $2,000 minimum per property; confirm the commercial engagement scope, and competitor fees are not inferred from unverified third-party directories.
Your next step
Discuss your property
Bring the property type, acquisition and placed-in-service dates, approximate basis, improvement history and existing depreciation schedule. AE Tax Advisors hosts discovery; confirm the study scope and any separately engaged tax implementation.
