Federal Way's Building Safety: The Rules That Matter

Every city handles building safety a little differently. In Federal Way, Washington, there are 5 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.

Childcare Center Rules

Federal Way requires commercial day care and school-type childcare centers to pass Process II site plan review under Federal Way Revised Code 19.210.020 before opening in the professional office zone and comparable commercial districts. The code mandates a fenced outdoor play area sized to enrollment and sets a floor-area-based parking ratio the Community Development Department checks at permit intake.

Key details: Governing section: FWRC 19.210.020. Review process: Process II, possibly Process III. Outdoor play area: 75 sq ft per child, enclosed. Fence height: At least 6 feet, solid screen. Play equipment setback: At least 10 feet from property line.

Operating a commercial day care center without the Process II land use approval FWRC 19.210.020 requires, or building the center without the outdoor play area, the six-foot solid fence, or the 10-foot play equipment setback the section mandates, is a zoning violation. The city can withhold occupancy or site plan approval, require corrective construction to the required play-area and fencing dimensions, and issue a stop-work order until the site conforms before any children are cared for on the property.

Building Permits

Federal Way requires a building permit for construction work under the adopted 2021 International Building Code, and FWRC 13.16.030 tightens the standard IBC exemptions: work inside a mapped critical area always needs a permit, and only small detached accessory structures under 200 square feet and 10 feet of wall height skip the permit step.

Key details: Code adopted: 2021 International Building Code (FWRC 13.16.020). Critical-area work: Permit always required, no exemptions apply. Shed exemption: 200 sq ft or less, 10 ft wall height max. Amended-permit fee: Set by city fee resolution. Appeal deadline: 14 days to hearing examiner.

Building without the required permit, or performing critical-area work under the mistaken belief that the IBC's standard exemptions apply, is enforced under the FWRC 1.10.010 general penalty: a misdemeanor punishable by up to a $1,000 fine, up to 90 days in jail, or both, with each day of unpermitted construction charged as a separate violation the building official can refer for civil abatement under Chapter 1.15 FWRC.

Fire Sprinkler Requirements

Federal Way's fire code goes beyond the base IBC and IFC sprinkler triggers: FWRC 13.31.050 requires an approved automatic sprinkler system in any new building lacking adequate fire flow or fire department access, and in any occupancy other than single-family homes or utility buildings once total floor area across all levels, including basements, tops 5,000 square feet.

Key details: General rule: Fire sprinkler systems shall be installed. Size trigger: 5,000+ sq ft, all levels, non-R3/U. R3 exemption: Single-family additions exempt if fire flow OK. Fire-flow credit: Up to 50% reduction with NFPA 13/13R. Minimum reduced flow: 1,500 gallons per minute.

Constructing or occupying a building that triggers FWRC 13.31.050 without installing the required automatic sprinkler system is enforced as a fire code violation under the citywide criminal penalty at FWRC 1.10.010: a misdemeanor carrying up to a $1,000 fine, up to 90 days in jail, or both, and the fire code official can also order the work or occupancy to cease under Chapter 1.15 FWRC.

Plumbing Permits

Federal Way plumbing work runs under the 2021 Uniform Plumbing Code, adopted by FWRC 13.34.020 with the venting, combustion-air, and building-sewer chapters carved out and sent to other city codes. A plumbing permit issued under this chapter expires if the work does not start, or sits abandoned, for 180 days, per the local amendment at FWRC 13.34.030(2).

Key details: Code adopted: 2021 Uniform Plumbing Code (UPC). Permit expiration: 180 days if work not started. Abandonment limit: 180 days suspended voids permit. Extension available: Building official may grant 180-day extensions. Lapse over 1 year: Requires new full permit fee.

Plumbing work performed after a permit has expired under FWRC 13.34.030(2), or without a permit at all, is enforced under the citywide misdemeanor penalty at FWRC 1.10.010: up to a $1,000 fine, up to 90 days in jail, or both, and the building official may require a full new permit fee before reviving work suspended more than a year.

Electrical Permits

Federal Way electrical work is governed by the 2023 National Electrical Code, adopted at FWRC 13.38.020 along with the state's WAC electrical safety chapters, and every installation needs a permit unless it falls into one of the narrow exemptions the city carved out in FWRC 13.38.040, such as temporary decorative lighting or theater stage wiring.

Key details: Code adopted: 2023 National Electrical Code (NEC). State chapters: WAC 296-43, 296-45, 296-46B. Permit exemptions: Decorative lighting, lab wiring, stage sets. Existing wiring: Grandfathered unless deemed dangerous. Max penalty: $1,000 fine and/or 90 days jail.

Performing electrical work without a required permit, or outside the FWRC 13.38.040 exemptions, is enforced under the citywide misdemeanor penalty at FWRC 1.10.010, punishable by up to a $1,000 fine, up to 90 days in jail, or both, with each day of the unpermitted installation charged as a separate violation.

The Bottom Line

Federal Way'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 Federal Way is broadly strict or permissive.
