Section 2: Existing Fire Protection Systems

Required — complete before proceeding

Both questions in this section are required. Eastside Fire & Rescue uses this information to determine applicable life safety requirements. This section cannot be skipped.

Existing automatic fire sprinkler system?

Yes No

Monitored household fire alarm system per NFPA 72?

Yes No

Monitored household fire alarm vs. smoke alarms — what's the difference?

A monitored household fire alarm system (NFPA 72, Chapter 29) is a centrally supervised system installed by a licensed fire alarm contractor under permit. It includes smoke detectors, notification appliances, and a connection to a 24-hour monitoring station. Installation requires a fire alarm permit and final inspection by Eastside Fire & Rescue.

This is different from:

Interconnected smoke alarms (hardwired or battery, including 10-year sealed models) — required under the IRC but do not constitute a monitored household fire alarm system
Networked consumer devices (Nest, Ring, SimpliSafe, etc.) not listed under NFPA 72 and installed without permit
Any system not connected to a 24-hour monitoring station or approved monitoring point

If you are unsure whether the existing system qualifies, select No. Your plan reviewer will verify during review.

Section 3: Construction Valuation Type

Select the tier that best describes the construction quality of the existing structure. Eastside Fire & Rescue verifies the selected tier against the King County Assessor's building grade as a matter of routine intake review.

Good — $213.27/sf

Basic construction, standard-grade materials, meets code minimums. Typical of utility structures, unfinished accessory buildings, and budget additions. Corresponds roughly to King County Assessor Grade 7 (average).

Very Good — $272.51/sf Most common — select if unsure

Above-average quality materials and workmanship. Typical finish level for most permitted residential projects. Corresponds roughly to King County Assessor Grade 8 (good) to Grade 9 (better).

Very Good Custom — $331.75/sf Substantiation required

High-end custom design, premium materials, upgraded mechanical and electrical systems, above-standard architectural detailing. Corresponds roughly to King County Assessor Grade 10–11.

Luxury Custom — $450.23/sf Substantiation required

Top-tier construction, premium or imported materials, bespoke finishes, architect-supervised execution. Corresponds roughly to King County Assessor Grade 12–13.

Section 2: New Construction — Gross Floor Area

IBC Definition — Gross Floor Area

Gross floor area is the area in square feet under the roof line of the structure, including all usable space whether heated or not, above and below grade. This includes the attached garage and any unheated storage rooms or attachments including covered decks. If it is usable space, include it.

This is not the same calculation as the gross floor area (GFA) ratio used for zoning purposes.

Section 4: Existing Building — Square Footage & Standardized Value

IBC Definition — Gross Floor Area

Gross floor area is the area in square feet under the roof line of the structure, including all usable space whether heated or not, above and below grade. This includes the attached garage and any unheated storage rooms or attachments including covered decks. If it is usable space, include it.

This is not the same calculation as the gross floor area (GFA) ratio used for zoning purposes.

Enter current square footage for each space type. Standardized values calculate using the tier rate selected in Section 3. Attached garage, covered decks, and other unfinished space use a flat rate of $43.99/sf regardless of tier.

Section 5: 60-Month Prior Permit History

Under AWV107.2, the construction value of all additions, alterations, or repairs at this address within a rolling 60-month period is cumulative. Prior permitted work is added to the current project value when calculating the threshold percentage.

Has there been other permitted work at this address in the last 60 months?

Yes — prior permitted work exists within the last 60 months No — no prior permitted work at this address within the last 60 months I cannot verify — I am unable to determine the complete permit history at this address

Acknowledgment Required

You have indicated that you cannot verify prior permit history at this address. Eastside Fire & Rescue will verify permit history as a matter of routine intake review. Any prior permitted work within the rolling 60-month period may be included in the cumulative valuation under AWV107.2, which may affect the applicable life safety threshold for this project.

I acknowledge that Eastside Fire & Rescue will verify the 60-month permit history at this address, and that prior permitted work, if identified, may be included in the cumulative threshold calculation.
