About each permit

General Business License — King County position (state license applies)

The County's own Local Services page states plainly that 'King County does not have a business license requirement, but all businesses in the state must get a Washington State business license,' so this record carries no fee, and Public Health's food-business page confirms the County 'does not require a separate business license for establishments in unincorporated King County.' The universal registration is the Washington State business license, recorded at the state layer. What the County does license is a short, named list of specific activities in Title 6 of the King County Code — amusement devices, public entertainment, massage and public bathhouses, junk shops, secondhand dealers, pawnbrokers, cannabis retail, heating and air-conditioning installers and a handful of others — each listed separately where it reaches one of the ten industries. One further Title 6 license is listed inconsistently: King County Ordinance 19030 created an 'adult beverage business' license for wineries, breweries, distilleries, cideries and remote tasting rooms operating in unincorporated King County, priced at $100 a year, and the County's 2026 Fee Guide 10 still lists it, but the chapter does not appear in the King County Code as currently published and it is not on the Local Services license list. Ask King County Permits, (206) 296-6600, whether it is still collected before relying on either its presence or its absence. Food, pet, pool, septic and (in three places) plumbing permits come from Public Health and apply county-wide, including every city. Cities inside King County — Seattle, Bellevue, Kent, Renton and the rest — run their own business licenses, out of scope here.

Commercial Tenant Improvement / Alteration / Change of Use Permit (unincorporated King County)

Fitting out or altering a leased space in unincorporated King County uses the same valuation-based plan review and inspection fees as new construction (see that record), including the $25 state building code surcharge and, where applicable, the $126 screening fee. A change of use with no building alterations costs a flat $970 plan review plus $419 inspection in 2026; if alterations are included, the valuation-based fee is charged instead. Work started without a permit is charged an investigation fee of $1,936 for commercial alterations and $8,128 for a new commercial structure (KCC 27.10.425) on top of the regular fees, and a pre-application conference is $5,809. Plan re-submittal after the second round, or a revision to an issued permit, is charged 25% of the original application fee. This is the 2026 fee schedule; King County Code sets a lower fee effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027. Public Health separately approves plumbing, septic and food plans; King County Permits' own forms route food-business plans through a 'Health Department Approval of Building Permit Application' step.

Certificate of Occupancy (unincorporated King County)

A certificate of occupancy is issued by King County Permits after final inspection of a permitted commercial building or tenant space in the unincorporated area: KCC §16.02.480 requires it once 'no violations of this code or of related land use and public health ordinances, rules and regulations have been discovered, or if such violations have been discovered and corrected.' There is no separate fee for a certificate covering one, fully completed building, because it is covered by the building permit's own inspection fee. The 2026 fee guide has four priced scenarios under KCC §27.10.510: $442 for a certificate covering an individual townhouse or a portion of a building not completely constructed, and $970 each for a temporary certificate of occupancy per building or tenant space, a certificate covering more than one building under a single permit, or a letter of completion for shell construction covering more than one building. This is the 2026 fee schedule; King County Code sets a lower fee ($387 and $849 respectively) effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027. Inside a city, that city issues the certificate instead.

Zoning Certification Letter

A written zoning certification from King County Permits confirming a parcel's zoning designation or development rights in the unincorporated area costs $483 in 2026, or $1,452 if historic research or review of other information is needed. It is optional; the County's interactive zoning map is free to consult. This is the 2026 fee schedule; King County Code sets a lower fee ($423 and $1,271) effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027. Every unincorporated-area business must follow King County's zoning code (Title 21A) whether or not it obtains a certification letter.

Salon / Cosmetology Licensing — State License Applies (King County)

Salon and cosmetology licensing is a Washington State Department of Licensing function, recorded at the state layer, and the County's business-license list names no salon license, so this record carries no fee at the county level. The Board of Health's only cosmetology chapter, Title R18, covers ear-piercing sanitation standards alone, with no permit or fee, and neither the County's current business-license list nor Title 6 has a cosmetology, barber or nail license. Two County licenses can still reach a salon in the unincorporated area: the public bathhouse license if it offers baths, saunas or hot tubs, and the massage license if it provides massage outside a state-licensed cosmetologist's authorized scope of practice (see the massage and bathhouse record). Ordinary building, sign and, in Seattle, Clyde Hill and unincorporated King County, plumbing permits apply to a salon's premises as they would to any commercial space.

Commercial Building Permit — New Construction (unincorporated King County)

In unincorporated King County a new commercial building needs a building permit from King County Permits (Department of Local Services). The fee has two parts calculated from the County's construction valuation: plan review starting at $103 plus $27.40 per $1,000 up to $25,000 (reaching $1,988 at $100,000 of value) and inspection starting at $183 plus $44.60 per $1,000 up to $25,000 (reaching $3,153 at $100,000), plus a $126 application screening fee for most permit applications requiring plan review and screening, plus a flat $25 state building code surcharge that Washington law sets as the minimum fee on a building permit (it does not apply to mechanical, fire-protection or tank permits). This is the 2026 fee schedule; King County Code sets a lower fee effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027. Fire systems, plumbing, signs and land-use approvals are billed separately. Electrical permits and contractor registration come from the state (Labor & Industries). Inside a city, that city's own permit applies instead.

Commercial Sign Permit (unincorporated King County)

A new, altered or relocated sign in unincorporated King County needs approval from King County Permits: $1,597 plan review plus $737 inspection, $2,334 in total for 2026, plus the application screening fee where it applies; multiple similar wall signs on one structure pay a single fee. Repainting, cleaning and face or copy changes that do not alter the size or structure of a sign are exempt from the building permit requirement. Sign area and type limits vary by zone (KCC 21A.20.060-.110). This is the 2026 fee schedule; King County Code sets a lower fee ($1,398 plus $645, $2,043 total) effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027. Signs inside a city are permitted by that city instead.

Conditional Use Permit

A conditional use permit is required in unincorporated King County only where the zone's land-use table (KCC 21A.08) marks a use 'C'. The 2026 fee is $13,266 for a commercial use, $18,106 for an industrial, institutional or other use, and $6,487 for a residential or home industry use, plus environmental review if triggered. Special use permits are $18,106 and other temporary use permits $10,360. KCC 21A.08.030 marks 'Home Industry' as a conditional use in the A, RA, UR and R-1 zones: this is the route by which a use barred outright as a home occupation — for example auto repair or a veterinary clinic in a residential zone — can still be permitted, at $6,487, though wineries, breweries, distilleries and cannabis retail remain barred as home industries too. This is the 2026 fee schedule; King County Code sets lower fees ($11,610 / $15,846 / $5,677, and $15,846 for special use, $9,067 for other temporary use) effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027.

Home Occupation — Allowed Under Zoning Standards (King County)

No fee applies. King County charges no permit fee for a home occupation in unincorporated King County; it is allowed as an accessory use if it meets zoning standards, and which uses are barred depends on the zone. In the R, UR, NB, CB and RB zones (KCC 21A.30.080.E), a home occupation may not be automobile, truck or heavy-equipment repair, auto body work or painting, a veterinary clinic, recreational cannabis processing, production or retail, or a winery, brewery, distillery or remote tasting room. In the A, F and RA zones (KCC 21A.30.085.J) the barred list is shorter and different: hotels, motels or other lodging; dry cleaning; automotive towing, wrecking or tow-in lots; recreational cannabis; and winery, brewery, distillery or remote tasting-room uses — auto repair and veterinary clinics are NOT barred as home occupations in these agricultural, forest and rural zones. The two zone groups also differ on the operating standards themselves: the R/UR/NB/CB/RB zones require indoor-only operation, one non-resident employee, appointment-only patron service and one business vehicle, while the A/F/RA zones allow limited outdoor operation, up to three non-resident employees, no appointment-only restriction and two to four vehicles; both cap floor area devoted to the occupation at 20% of the dwelling. A use barred outright as a home occupation may still be reachable through a home industry conditional use permit (see that record). Regulated activities such as massage still need their own Title 6 license, and food businesses still need a Public Health permit regardless of zone.

Massage Business / Public Bathhouse License

In unincorporated King County a massage business, or any place furnishing baths of any kind — including Finnish, Russian, Swedish and Turkish baths, saunas, steam rooms and hot tubs at a gym or salon, but not an ordinary tub or shower where no attendant is required — needs a $150-a-year public bathhouse or massage business license expiring each November 30, valid for one location; individual massage practitioners pay $50. Per the County's own license page, businesses of the kind that need this license include hot tub establishments, sauna establishments, beauty salons and athletic clubs offering bath facilities; the code itself exempts barbers and cosmetologists from needing the license for massage practiced within their state-authorized scope of practice, but sets no exemption for a state-licensed massage practitioner who owns their own massage business, so the $50 practitioner fee still applies unless the business itself qualifies for the cosmetologist exemption. An ordinary hair, nail or skin salon without bath facilities and without massage service beyond a cosmetologist's authorized scope does not need a license under this chapter. Applications are inspected by the Sheriff's Office and Permitting. This Title 6 fee is fixed in the code and is not affected by the Local Services fee schedule that expires January 1, 2027.

Contractor Registration — State Labor & Industries Applies (King County)

No fee applies at the county level. RCW 18.27.020(1) requires every contractor to register with the Washington State Department of Labor & Industries, and RCW 18.27.020(2)(a) makes it a gross misdemeanor to advertise, bid or perform work as a contractor without that registration. King County Code §16.32.275 itself directs plumbers and contractors to 'comply with all applicable state or local rules and regulations concerning plumber certification and contractor registration' rather than adding a county credential of its own, and L&I also issues electrical permits in unincorporated King County. The only county-level contractor credentials are the $50-a-year HVAC installers license (KCC 6.32) and the $183 annual tank-removal contractor certification (KCC 27.10.580.C), both listed separately. A contractor building in the unincorporated area obtains building, mechanical and fire permits from King County Permits, plumbing and gas permits from Public Health (in Seattle, Clyde Hill and unincorporated King County only), and each city's own permits elsewhere.

Zoning Variance

A zoning variance in unincorporated King County costs $13,266 for review and $483 for an extension of approval in 2026. This is the 2026 fee schedule; King County Code sets a lower fee ($11,610 review, $423 extension) effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027.

Secondhand Dealer's License

In unincorporated King County a business that buys, sells, trades or takes on consignment secondhand goods — antique and consignment shops, and repair garages dealing in used or remanufactured items including used tires and parts — needs a $40-a-year secondhand dealer's license, payable December 31 for the following year and prorated quarterly if issued mid-year. Used motor vehicles and boats are excluded from the definition, as is anything already covered by the junk-shop license. Applications are reviewed by the King County Sheriff's Office and by Permitting for fire, building and zoning compliance. This Title 6 fee is fixed in the code and is not affected by the Local Services fee schedule that expires January 1, 2027.

Pawnbroker's License

A pawnshop in unincorporated King County needs a $500-a-year pawnbroker's license, payable December 31 for the following year and prorated quarterly if issued mid-year, with Sheriff's Office record-keeping and reporting requirements. This Title 6 fee is fixed in the code and is not affected by the Local Services fee schedule that expires January 1, 2027.

Auto Repair Shop — County License Touchpoints (King County)

The County's business-license list and Title 6 name no automotive repair shop license as such, so this record carries no fee. A repair garage that deals in used or remanufactured parts or tires needs the $40 secondhand dealer's license in the unincorporated area, and one that buys or stores scrap or salvage may need a junk shop license instead. Fire-code operational permits, plumbing permits (in Seattle, Clyde Hill and unincorporated King County), on-site sewage approval, and, for process wastewater from cleaning or rinsing, Industrial Waste Program approval, can all apply. Automotive repair and body work are barred as home occupations in the R, UR, NB, CB and RB zones (KCC 21A.30.080.E.1-2), though not in the A, F and RA zones. The trade credential itself is the state Motor Vehicle Repair Dealer license, recorded at the state layer.

Heating, Air-Conditioning, Ventilation Systems and Equipment Installers License

King County Code sets a license fee of $50 a year, expiring each June 30, for any business selling, installing, altering or repairing heating, air-conditioning, ventilation or exhaust equipment in unincorporated King County, backed by a $1,000 surety bond under KCC §6.32.030. The chapter is codified in Title 6 and in force in the current text, but the County's own current business-license page and its 2026 Fee Guide 10 do not list this license among those it processes today. Ask King County Permits, (206) 296-6600, whether it is actively issued before applying or before assuming a contractor holds it. It is in addition to state contractor registration (Labor & Industries) and the mechanical permit, which is priced under the valuation-based building permit fees.

Tank Removal Contractor Annual Certification

Contractors who remove or decommission fuel tanks in unincorporated King County — the County's application describes the scope as fuel tanks generally and requires state licensing plus ICC UST-certified staff, not only residential heating-oil tanks — are certified annually by King County Permits; the fee is the minimum inspection-fee amount set in KCC §27.10.320.A.1, $183 in 2026. This is not the County's only Title 6 or Title 27 contractor credential: heating, air-conditioning and ventilation installers separately need the $50-a-year HVAC installers license under KCC 6.32 (listed separately), so tank-removal certification should not be treated as the sole county-level contractor credential. General contractor registration itself remains a state Labor & Industries requirement. This is the 2026 fee schedule; King County Code sets a lower fee ($160) effective January 1, 2027, unless the Council adopts a new fee ordinance first (one was due to the Council by October 1, 2026). Confirm the current fee with King County Permits, (206) 296-6600, after January 2027.

Junk Shop / Junk Wagon License

A business in unincorporated King County where scrap metal or other junk — old rope, iron, brass, copper, tin, lead, rags, bottles, paper, bagging and other worn-out or discarded material — is bought, received or stored needs a $300-a-year junk shop license; a vehicle collecting junk door to door needs a $40 junk wagon license instead. Purchases by automobile wreckers who buy vehicles with a certificate of title are excluded from the junk-shop definition. Applications are reviewed by the Sheriff's Office and by Permitting. This Title 6 fee is fixed in the code and is not affected by the Local Services fee schedule that expires January 1, 2027.

Novelty Amusement Device / Pool Table / Public Amusement Licenses

In unincorporated King County a restaurant, tavern or venue that keeps coin-operated novelty amusement devices pays $100 per device a year under KCC §6.04.040 — except a shuffleboard, which KCC §6.04.180 prices separately at $50 per year, not $100 like other novelty devices. Pool or billiard tables cost $100 per table up to $500 per establishment and expire one year from the date of application; offering live entertainment, skating, bowling, arcades or pool halls to the public needs a $200-a-year public amusement license ($100 for six months, $50 for one night). Novelty devices may not operate within 500 feet of a school. Serving food and drink alone needs none of these licenses. This Title 6 fee is fixed in the code and is not affected by the Local Services fee schedule that expires January 1, 2027.

Retail Cannabis Business License

A retail cannabis store in unincorporated King County needs a County business license — $1,000 a year, or $500 with a current Washington State Liquor and Cannabis Board medical cannabis endorsement — in addition to its state Liquor and Cannabis Board license. The license's term is set by KCC §6.70.060: it 'expires one year from the date the business license is issued,' not on a fixed calendar date such as January 1, and a renewal application must be submitted to the Director at least 30 days before that one-year expiration date. Cannabis retail is barred as a home occupation in both the R/UR/NB/CB/RB zones and the A/F/RA zones. This Title 6 fee is fixed in the code and is not affected by the Local Services fee schedule that expires January 1, 2027.
