How much does a commercial hood suppression permit cost in Washington DC in 2026

Most restaurant and commercial kitchen owners in Washington DC pay $200 – $750 for a hood suppression permit in 2026, driven by declared construction value, whether the grease duct and ventilation are part of the scope, plan review, and the District’s percentage surcharges.

A commercial kitchen hood system combines two things: the fire-suppression system over the cooking appliances and the exhaust hood with its grease duct. In DC, the suppression side and the mechanical side can travel on separate permits, and the Department of Buildings (DOB) treats fire-suppression as fire-protection work. That split is where budgets go wrong. Here is the realistic range.

Cost breakdown (2026)

Fee component	Typical 2026 cost
Filing fee	$32
Base permit fee (tiered by construction value)	$33 – $150
Fire-suppression trade permit	$120 – $350
Mechanical permit for hood / grease duct	$65 – $200
Plan review (when required)	$50 – $200
Technology fee (10%)	~10% of permit fee
Enhancement fee (6%)	~6% of permit fee
Inspection	Included with permit
Typical total	$200 – $750

If your build-out also touches gas lines or electrical circuits for the kitchen, those pull their own permits — see gas line permit costs and DC building permit costs for the rest of the project.

What affects the price

• Declared construction value. The main driver. Swapping an existing hood system declares little value; a full kitchen build-out with new hood, duct, and appliances declares far more, and the fee scales with it.
• Grease duct length and routing. Long runs, rooftop terminations, and fire-rated enclosures add scope and inspection points.
• Historic district review. Restaurants in historic districts may need review for rooftop exhaust or visible equipment, adding time and potential fees.
• Expedited processing. DOB expedites for a fee — usually only worth it when a lease or health inspection deadline looms.
• Agency add-ons. Zoning sign-offs for a change of use, right-of-way work for curb-side grease containers, or utility coordination add separate costs.

How the fee is calculated

DOB layers the hood suppression cost rather than quoting one number. Under the DOB fee schedule (2026):

1. Filing fee: roughly $32, charged up front.
2. Base permit fee: tiered by declared construction value — roughly $148 for the first $1,000 of value, then about $10 per additional $1,000. Minimum flat tiers for very low-value work run around $33 – $65.
3. 10% technology fee: added on top of the permit fee.
4. 6% enhancement fee: also added on top.
5. Zoning fee: where a zoning review applies.

The fire-suppression and mechanical permits each carry their own modest valuation-based fee, and both are subject to the same percentage surcharges. That is why a small suppression job’s all-in permit cost usually lands nearer the top of the range once the mechanical side is included. The rule of thumb: fees scale with declared construction value.

Timeline & steps

1. Hire licensed DC contractors — a fire-protection contractor for suppression and a mechanical contractor for the hood and duct.
2. File via CitizenAccess. Submit the appliance list, hood UL listing, and suppression design with declared value through DOB’s portal.
3. Plan review: simple like-for-like hood swaps can clear in 1 – 2 weeks; new kitchens and duct work typically take 2 – 4 weeks.
4. Install and inspect: after installation, the contractor schedules the DOB inspection before the kitchen is cleared to operate.
5. Closeout: both permits must pass so your certificate of occupancy or health approval is not blocked.

Common mistakes

• Pulling only the suppression permit. The hood, fan, and grease duct need a mechanical permit too — a half-permitted kitchen fails inspection.
• Ignoring the appliance list. Suppression systems are sized to specific appliances; adding a fryer later can invalidate the approval.
• Understating declared value. It triggers corrections and delays your opening.
• Letting permits lapse. An open permit blocks occupancy and turns up at sale or refinance.

FAQ

Do I need both a suppression permit and a mechanical permit?

Usually yes. The fire-suppression portion is a fire-protection permit, while the exhaust hood, fan, and grease duct require a mechanical permit. Both must pass inspection before the kitchen is approved.

Is plan review required for a commercial hood in DC?

Simple like-for-like replacements may skip full review, but new hoods, ducts, and kitchen build-outs are typically reviewed, adding cost and time.

Do the 10% technology fee and 6% enhancement fee apply?

Yes. Both surcharges apply on top of the base permit fee under the DOB fee schedule (2026), raising the effective total above the base permit figure.

How long does approval take?

Expect 1 – 4 weeks depending on scope and whether plan review is required, plus inspection scheduling after installation.

Can a restaurant owner pull the permit?

Generally no. DC requires licensed contractors to pull fire-protection and mechanical trade permits. The owner signs as property owner; the licensed contractor is the applicant of record.
