Endelman & Associates

What Endelman & Associates does

Endelman & Associates PLLC is a Seattle-headquartered accessibility compliance consultancy founded in 1997 by William E. Endelman, now led by Principal Michael B. Schneider, AIA, NCARB, LEED AP, CASp. The firm provides Americans with Disabilities Act (ADA) surveys, Fair Housing Act (FHA) plan reviews and site observations, code compliance consulting, due diligence surveys, and litigation/expert witness services to multifamily housing developers, architecture firms, public entities, and attorneys across more than 30 U.S. states and into British Columbia, Canada. Notable engagements include work for the U.S. Department of Justice as an outside consultant and testifying witness, as well as projects for AvalonBay, Greystar, Wood Partners, Lincoln Property, Trammell Crow, Mill Creek Residential, University of Arizona, King County, and Pike Place Market.

The firm operates on a project-based professional services model with multi-year contracts and bills against scope, travel, and complexity rather than published rate cards. Its central technology asset is a proprietary ADA Survey Solutions Software platform used to standardize field surveys, manage barrier-removal workflows, and generate client deliverables. A staff of approximately 12, including multiple CASp-certified consultants and architects with AIA, NCARB, and LEED AP credentials, delivers work both from the One Union Square office in Seattle and via regional and national travel. There is no evidence of external funding, M&A, or institutional ownership; the firm is privately held and appears to be founder/principal-owned.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Perkins&Will: Global architecture practice with substantial in-house accessibility expertise serving healthcare, education, and civic clients - parallels Endelman's institutional/hospital/government workload from a much larger platform.
• SmithGroup: Major U.S. architecture firm with a dedicated accessibility practice providing ADA/FHA consulting on healthcare, education, and workplace projects at national scale - parallels Endelman's institutional client work from a much larger platform.
• Stantec: Large global AEC firm with an established accessibility consulting practice - competes with Endelman on multi-unit housing, institutional, and public-sector accessibility reviews from a much broader portfolio and larger bench.
• Wiss, Janney, Elstner Associates (WJE): National engineering/architecture consulting firm conducting investigative, code-compliance, and building-condition studies - directly analogous to Endelman's sub-consulting work on accessibility and due-diligence surveys.
• Heery International: Historic AEC/PM firm where founder William Endelman previously served as ADA Program Manager - overlapping accessibility program management capabilities and a natural strategic acquirer in this space.

Emerging players

• AudioEye: Public digital accessibility SaaS company providing automated ADA testing and remediation for websites - adjacent to E&A's built-environment accessibility focus and illustrative of the digital-physical divide in the accessibility market.
• Level Access: Digital accessibility SaaS and services firm operating in the broader accessibility market but focused on web/digital ADA compliance rather than physical building accessibility - adjacent emerging player to E&A's built-environment focus.

Direct peers

• Accessology: California-based accessibility consulting firm providing ADA/FHA plan reviews, CASp inspections, and accessibility training across multiple states - directly overlapping Endelman's core service portfolio and customer segments.
• Studio Pacifica Ltd (Karen Braitmayer): Karen Braitmayer's Seattle-based architecture firm specializing in accessibility consulting for buildings - a near-identical niche to Endelman & Associates. Endelman already partners with Studio Pacifica as a sub-consultant on accessibility surveys, evidencing direct service overlap.
• Collaborative Services Inc. Sacramento-headquartered firm providing ADA compliance services, accessibility audits, and transition plans to public agencies and developers - directly overlapping Endelman's public-sector and developer-facing ADA work.
