Seattle BEPS reporting deadlines and provider roles
Understand Seattle Building Emissions Performance Standard reporting dates, annual benchmarking, Qualified Person roles, and the services to research next.
First reporting datesOctober 1, 2027 for buildings over 90,000 square feet; 2028 for 50,001–90,000; 2029 for 30,001–50,000; and 2030 for 20,001–30,000. Annual benchmarking remains a separate June 1 deadline.
How to use this guide
Verify the exact scope.
Seattle's Building Emissions Performance Standard adds a city reporting and emissions track for covered existing buildings. The first interval requires benchmarking verification and a greenhouse gas report; later intervals require emissions targets or an allowed alternative path.
The city portal lists separate annual benchmarking and BEPS deadlines. It also states that BEPS reporting must be completed by a Qualified Person and that the entity performing benchmarking verification cannot be the same entity that submits the annual benchmarking report. Define those roles before hiring one firm for every task.
Five size cohorts
Track the first BEPS report separately from annual benchmarking.
The October BEPS year changes by building size. Annual Seattle benchmarking is still due June 1 each year, including the year a BEPS report is due.
90,001 through 220,000 square feet
The first BEPS reporting date is October 1, 2027. Annual benchmarking is due June 1. The first emissions-target year is 2032.
50,001 through 90,000 square feet
The first BEPS reporting date is October 1, 2028. Annual benchmarking is due June 1. The first emissions-target year is 2033.
30,001 through 50,000 square feet
The first BEPS reporting date is October 1, 2029. Annual benchmarking is due June 1. The first emissions-target year is 2034.
20,001 through 30,000 square feet
The first BEPS reporting date is October 1, 2030. Annual benchmarking is due June 1. The first emissions-target year is 2035.
Common questions
Understand the service before comparing firms.
Short answers grounded in public program and federal guidance. The written scope still controls each engagement.
What is due in the first Seattle BEPS interval?
Seattle describes the 2027–2030 interval as benchmarking verification and greenhouse-gas reporting. The exact year depends on building size. Later 2031–2035 dates introduce the first emissions targets for nonresidential buildings.
Is annual benchmarking part of the same deadline?
No. The city portal lists annual Energy Benchmarking as a separate June 1 deadline. In a BEPS compliance year, the owner must track both the June benchmarking deadline and the October BEPS deadline.
Who can complete BEPS reporting?
The city portal states that BEPS compliance reporting must be completed by a Qualified Person. It also states that benchmarking verification cannot be performed by the same entity that submits the annual benchmarking report.
Before hiring
Questions worth asking every finalist.
- Which city building record, size cohort, and BEPS deadline apply?
- Who submits annual benchmarking, and who independently performs benchmarking verification?
- Who serves as the Qualified Person for the BEPS report, and what credentials will be documented?
- What greenhouse-gas calculations, assumptions, planning materials, and owner approvals are included?
- How will this Seattle scope coordinate with any Washington Clean Buildings requirements without merging the two submissions?
