Auburn's Building Safety: The Rules That Matter

Every city handles building safety a little differently. In Auburn, Washington, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Scaffold & Sidewalk Shed

Scaffolding at Auburn construction sites follows Washington State Building Code (RCW 19.27) and WISHA safety rules, with permits required for scaffolds over 10 feet and right-of-way encroachments needing city approval.

Key details: Code: RCW 19.27 + WAC 296-874. Permit Trigger: Over 10 feet or attached. Right-of-Way: Separate ROW permit required. Guardrails: 42 inches with midrail and toeboard. Power Line Clearance: 10 feet minimum.

Plumbing Permits

Auburn adopts the 2021 Uniform Plumbing Code by reference under ACC 15.07.010(D)(8) and classifies plumbing permits as Type I administrative decisions. Applicants file with the department of community development, pay plan-review and permit fees, and rough-in plumbing must be inspected before any connection to primary utilities.

Key details: Adopted code: 2021 Uniform Plumbing Code. Adopting section: ACC 15.07.010(D)(8). Permit classification: Type I administrative decision. Rough-in inspection: Required before utility connection. Appeal deadline: 20 calendar days.

Under ACC 15.07.140(E), failing to comply with the adopted plumbing code is a violation punishable as a misdemeanor, gross misdemeanor, or civil infraction depending on the underlying offense classification; where no specific penalty applies, a misdemeanor carries up to 90 days in jail and a $1,000 fine, and a gross misdemeanor carries up to one year and a $5,000 fine. The department of community development enforces building and plumbing codes, and the Auburn police chief may issue criminal citations when criminal sanctions apply.

Building Permits

Auburn requires a written permit application to the department of community development before any work covered by the adopted International Building, Residential, Mechanical, Fire, Fuel Gas, Plumbing and Energy Codes begins, per ACC 15.07.050. The application must identify the work, tax parcel, valuation, and the contractor's state registration and city license; work in the public way, on utility poles, or on flood-control structures is exempt under ACC 15.07.010(C).

Key details: Governing chapter: ACC 15.07, Construction Administrative Code. Permit applicant files with: Dept. of Community Development. Exempt work: Public way, utility poles, flood-control structures. Appeal deadline: 20 calendar days to hearing examiner. Misdemeanor penalty: Up to 90 days jail, $1,000 fine.

Working without a required permit, or failing to comply with the adopted technical codes, violates Title 15 under ACC 15.07.140(E). Absent a more specific penalty, the offense is a misdemeanor punishable by up to 90 days in jail and a $1,000 fine, or a gross misdemeanor punishable by up to one year and a $5,000 fine; the building official weighs the safety risk and compliance effort in setting the penalty.

Fire Sprinkler Requirements

Auburn's amended fire code, ACC 15.36A.041(C), mandates automatic sprinklers in most new buildings over 10,000 square feet, taller than 30 feet, or needing more than 2,500 gpm fire flow, plus any new building lacking adequate fire flow or emergency access, with Group R-3 and U buildings exempted from the size trigger.

Key details: Size trigger: >10,000 sq ft, >30 ft, or >2,500 gpm. Group A trigger: >8,000 sq ft of Group A occupancy. Exempt occupancies: Group R-3 and Group U (size trigger). Riser room: Dedicated fire-resistive room required. Penalty: Up to 90 days jail, $1,000 fine.

Occupying or building without the sprinkler system ACC 15.36A.041(C) requires is enforced under ACC 15.36A.071 as a misdemeanor: a jail term of up to 90 days and/or a fine of up to $1,000 for each violation, with every 10 days a prohibited condition continues counted as a separate offense. The fire chief or a court can also order corrective work within a fixed deadline.

This is not one of those rules that cities tend to ignore. Auburn actively enforces its fire sprinkler requirements requirements.

Building Inspections

Auburn's building official inspects construction in defined stages under ACC 15.07.090: a combined rough-in inspection for mechanical, gas, plumbing and electrical work before it is covered, a four-part energy-efficiency envelope inspection, and special inspections the official can order beyond IBC Chapter 17 requirements.

Key details: Rough-in inspection: Mechanical, gas, plumbing, electrical before covering. Envelope inspections: Wall insulation, glazing, roofing, slab (4 stages). Special inspections: Building official may order, no city cost. Utility connection rule: No hookup until rough-in approved. Penalty for violation: Up to 90 days jail, $1,000 fine.

Covering rough-in work, insulation, or glazing before the required inspection is approved, or connecting to primary utilities before rough-in sign-off, violates ACC 15.07.090 and is enforced under ACC 15.07.140(E) as a misdemeanor punishable by up to 90 days in jail and a $1,000 fine absent a more specific penalty, with the building official able to withhold a certificate of occupancy until the work is corrected.

Electrical Permits

Auburn does not run its own electrical permit program: ACC 15.28.010 requires all electrical wiring, equipment and appliances to conform to state statutes and states that no additional local permits or licenses are required beyond what state law demands, leaving inspection to the Washington Department of Labor & Industries.

Key details: Local electrical permit: None; state law controls. Governing statute: Chapter 19.28 RCW. Inspecting agency: WA Dept. of Labor & Industries. IRC exclusion: City IRC excludes Ch. 34-43 Electrical. Local code section: ACC 15.28.010, Electrical Code.

Because Auburn does not issue its own electrical permit, violations of electrical work are enforced under state law through Chapter 19.28 RCW and the Washington Department of Labor & Industries, not through a city citation. A contractor who performs electrical work in Auburn without the required state permit or the state contractor registration listed on a city building permit application under ACC 15.07.050 risks having that city permit application rejected as incomplete.

If you are coming from a city with tighter rules, you will find Auburn gives residents more flexibility on electrical permits.

Green Building Code

Auburn adopts the 2021 International Green Construction Code by reference under ACC 15.07.010(D)(13), but only as an optional guide for developers who choose to build to it; the city does not require any project to meet the code. Where the Green Construction Code conflicts with Auburn's own engineering or stormwater standards, the city's standards control under ACC 15.07.020(A).

Key details: Code adopted: 2021 International Green Construction Code. Mandatory status: Optional guidance only, not required citywide. Incentive path: Master plan height bonus under ACC 18.53.070. Conflict rule: City engineering standards override the Green Code.

Because ACC 15.07.010(D)(13) adopts the International Green Construction Code only as an optional guideline, there is no separate fine or permit denial for failing to build to it outside the master plan program. A developer who claims the ACC 18.53.070 height and fee-refund incentive without documenting the required Green Building Code certification risks losing that specific incentive during plan review by the planning and building divisions, not a code violation citation.

Auburn is more permissive than most cities when it comes to green building code. That said, there are still limits.

Elevator Maintenance

Auburn elevators are regulated by Washington Department of Labor and Industries under RCW 70.87 and WAC 296-96. Annual inspections, operating permits, and licensed contractor maintenance are required.

Key details: State law: RCW 70.87 / WAC 296-96. Agency: WA L&I. Operating permit: Required and posted. Inspection: Annual or biennial. Contractor license: Required for maintenance.

This is not one of those rules that cities tend to ignore. Auburn actively enforces its elevator maintenance requirements.

The Bottom Line

Auburn's building safety rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Auburn is broadly strict or permissive.

These rules come from Auburn's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
