Korea Barrier-Free (BF) Preliminary & Final Certification Fee Calculator

Calculate Korea’s official BF preliminary and final certification fees by facility type and area, with a potential 50% reduction, 10% VAT, cumulative cost, and renewal reference.

Certification inputs

Choose the target, area, and application stage to apply Korea’s current Attached Table 8 fees.

Certification target

Certified total floor area

m²

Enter one certification target. The next bands begin exactly at 300, 1,000, 3,000, and 10,000 m².

Application stage

Potential reduction

A 50% reduction is discretionary, not automatic. Select it only after the certification body confirms applicability.

Reference renewal fee after the 10-year term

This is 50% of the unreduced final-certification fee. Re-evaluation after an extension or reconstruction may change it, and the social-welfare reduction does not apply to renewal.

Net fee: KRW 2,418,000
VAT: KRW 241,800
Reference renewal total: KRW 2,659,800

The former temporary 1.25 multiplier for building Band 5 has expired. The current 1.5 multiplier applies in 2026.

A zero additional outlay excludes island travel, consulting, drawing revisions, and accessibility remediation work.

The notice generally requires payment within 20 days of application. Confirm the final fee, reduction, and actual outlays on the certification body’s invoice.

Why Korea’s BF certification fee changes by target, area, and stage

Korea’s Barrier-Free certification system reviews whether people with disabilities, older people, pregnant people, and other users can use a facility or area safely and conveniently.
It is commonly called BF certification.
A preliminary certification reviews accessibility reflected in design documents, while a final certification reviews the completed target through documents and an on-site inspection, so the two stages have separate fees.

Building-type individual facilities use five total-floor-area bands.
Parks, transport modes, passenger facilities, and roads use a separate fixed fee, while regional certification uses three area bands beginning at 100,000 m².
The official table also mixes KRW and units of KRW 10,000 and states that VAT is separate, which makes missed stages and tax omissions easy in a project budget.

Amounts this calculator keeps separate

Unreduced official preliminary and final certification fees
A potential 50% reduction that still requires certification-body confirmation
The post-reduction net fee and 10% VAT
The cumulative preliminary-to-final official amount
A standard renewal-fee reference after the final certificate’s 10-year term
Separately confirmed outlays such as island airfare or ferry cost

This is a Korea-specific calculator using rules rechecked on August 7, 2026.
The invoice issued by the accepting certification body controls the final payment, and this result does not decide whether certification is mandatory or whether a reduction applies.

Choose the certification target first

Building-type individual facility

Public buildings, publicly used facilities, multi-family housing, communication facilities, and similar targets use one certification target’s total floor area.
New bands begin exactly at 300, 1,000, 3,000, and 10,000 m².

Park, transport, passenger facility, or road

These individual facilities use the fixed fee in Attached Table 8 without an area input.
The unreduced net fees are KRW 2,860,000 preliminary and KRW 4,030,000 final.

Regional certification

Enter the certified area when an entire region is the target.
The official fee table starts at 100,000 m², so a smaller area requires direct classification and fee confirmation.

This calculator does not decide whether multiple buildings or different facility types may be combined in one filing.
If the certification body treats them as separate applications, calculate and budget each target separately.

Official fee table for building-type individual facilities

Attached Table 8 of the current joint BF fee notice sets a KRW 2,060,000 preliminary base and a KRW 4,030,000 final base, then applies the multiplier for the total-floor-area band.
Every amount below is a net fee before VAT.

Official preliminary and final BF certification fees by building total-floor-area band
Total-floor-area band	Multiplier	Preliminary	Final
Band 1 · under 300 m²	0.5	KRW 1,030,000	KRW 2,015,000
Band 2 · 300 to under 1,000 m²	0.8	KRW 1,648,000	KRW 3,224,000
Band 3 · 1,000 to under 3,000 m²	1.0	KRW 2,060,000	KRW 4,030,000
Band 4 · 3,000 to under 10,000 m²	1.2	KRW 2,472,000	KRW 4,836,000
Band 5 · 10,000 m² or more	1.5	KRW 3,090,000	KRW 6,045,000

Why the former Band 5 multiplier of 1.25 does not apply

Attached Table 8 still displays a transitional note that temporarily used 1.25 for Band 5.
That treatment lasted only until the day before one year had elapsed under the amended notice and had expired years before 2026.
The calculator therefore uses the current 1.5 multiplier and returns KRW 3,090,000 preliminary and KRW 6,045,000 final.

Regional and park, transport, passenger-facility, and road fees

The preliminary regional fee is KRW 4,290,000 in all three bands, while the final fee rises with the larger review and travel scope.
Parks, transport modes, passenger facilities, and roads use a separate fixed individual-facility amount.

Official preliminary and final BF fees for regional certification and parks, transport, passenger facilities, and roads
Target and area	Preliminary	Final
Region · 100,000 to under 2,000,000 m²	KRW 4,290,000	KRW 6,180,000
Region · 2,000,000 to under 3,000,000 m²	KRW 4,290,000	KRW 8,070,000
Region · 3,000,000 m² or more	KRW 4,290,000	KRW 9,950,000
Park, transport, passenger facility, or road	KRW 2,860,000	KRW 4,030,000

Attached Table 8 provides no regional fee band below 100,000 m².
The calculator does not silently borrow the first amount and instead limits regional input to at least 100,000 m².

How the calculation works

1. Select the official base fee

A building uses its total-floor-area band, a region uses its regional area band, and a park or transport-type target uses the fixed amount.
The lower boundary belongs to the next band, so a building of exactly 3,000 m² is in Band 4 rather than Band 3.

2. Apply one confirmed reduction

No reduction preserves the listed amount.
If the certification body confirms that the non-mandatory or social-welfare provision may apply, the calculator uses 50% of the base as the potential net fee.
It never stacks the two reasons into a 75% or larger reduction.

3. Add the selected stage and VAT

Selected net fee = selected preliminary fee + selected final fee
VAT = selected net fee × 10%
Official payment estimate = selected net fee + VAT
Total budget = official payment estimate + confirmed additional outlay

Attached Table 8 states that VAT is separate, and Article 30 of Korea’s current Value-Added Tax Act sets the rate at 10%.
The additional-outlay input is treated as the final tax-inclusive amount confirmed by the certification body, so the calculator does not tax it again.

Step-by-step use

Choose the certification target.Use the building-type choice for a public building, publicly used facility, multi-family housing, communication facility, or a similar target, and use the fixed choice for a park, transport mode, passenger facility, or road.
Enter the applicable area.Use total floor area for a building-type target and the certified regional area for regional certification.
Choose the application stage in this budget.Use preliminary for the design phase, final for the post-completion filing, or both for the full project cash plan.
Select a reduction only after confirmation.Do not assume that a private facility is non-mandatory; confirm both its legal status and the accepting body’s treatment.
Add VAT and confirmed actual outlays.Keep VAT on for a cash-payment budget and enter only quoted island travel or another documented extra amount.
Review the full breakdown.Compare the band, unreduced fee, potential reduction, net fee, VAT, cumulative amount, and renewal reference with the written quotation or invoice.

Worked examples for boundaries and cumulative cost

Example 1 · A 3,000 m² building

Exactly 3,000 m² is Band 4, producing KRW 2,472,000 preliminary and KRW 4,836,000 final.
With no reduction, the two-stage net fee is KRW 7,308,000 and 10% VAT is KRW 730,800, for a cumulative official amount of KRW 8,038,800.
The standard renewal net reference is 50% of the final fee, or KRW 2,418,000, and the VAT-inclusive reference is KRW 2,659,800.

Example 2 · Final certification at 10,000 m²

Exactly 10,000 m² is Band 5, and the current 2026 multiplier is 1.5, producing a final base fee of KRW 6,045,000.
If the certification body confirms the potential 50% non-mandatory treatment, the net fee is KRW 3,022,500.
Adding KRW 302,250 VAT produces an estimated official payment of KRW 3,324,750.

Example 3 · A 2,000,000 m² region

Exactly 2,000,000 m² enters regional Band 2.
The preliminary fee of KRW 4,290,000 and final fee of KRW 8,070,000 produce a KRW 12,360,000 net total.
With no reduction and VAT included, the cumulative official amount is KRW 13,596,000.

Example 4 · Preliminary filing with island travel

A 3,000 m² building has a preliminary net fee of KRW 2,472,000.
If the project accounts for VAT separately and the certification body quotes KRW 500,000 for round-trip island air or ferry travel, the total budget shown without VAT is KRW 2,972,000.
Tax treatment and supporting documents for the actual outlay still come from the invoice.

A 50% reduction and renewal fee are not automatic entitlements

Non-mandatory-facility treatment

Article 10-11 of the Accessibility Convenience Act and Article 4(2) of the current notice permit the fee for a non-mandatory facility to be set at 50%.
A private facility can still be mandatory depending on use and scale, and the wording is discretionary, so confirm the classification and actual treatment.

Social-welfare-purpose treatment

A facility installed or planned for a social-welfare business under Article 2 of the Social Welfare Services Act may also be charged 50% of the Article 4(1) fee.
Do not infer eligibility from the facility name alone, and note that the notice expressly excludes this reduction from renewal.

Why the renewal reference remains separate

Final certification is valid for 10 years, and Article 9 of the rule places the filing window from six months to two months before expiry.
Article 4(3) of the notice sets the standard renewal fee at 50% of the certification fee, but re-evaluation after an extension or reconstruction may change it.
The calculator therefore shows a conservative 50% reference based on the unreduced final fee and does not reapply the selected reduction.

Payment deadline and cancellation refunds

Article 5 of the current notice generally requires payment to the certification body within 20 days of the application date.
Failure to pay within that period can lead to return of the application, and the unpaid period is excluded from the processing period.

Refund percentage by BF certification cancellation stage under the current notice
Cancellation stage	Refund of paid fee
After acceptance but before a document-supplement request	90%
After acceptance but before certification review	70%
After review but before certification deliberation	30%
After certification deliberation	0%

The certification body’s filing and review record determines the actual stage.
Do not assume that the same percentage automatically refunds travel or another extra outlay already incurred.

Four practical planning scenarios

Design-stage budget

Place the preliminary fee and VAT in the design-stage budget and schedule the final fee separately at completion.

Bid and contract review

Separate the statutory certification fee from self-assessment preparation, drawing revision, consulting, and remediation bundled into a service quotation.

Public-project cash plan

Use the cumulative preliminary-plus-final amount, avoid an unconfirmed reduction, and align VAT treatment with the procuring entity’s budget rules.

Renewal planning

Work backward from the six-to-two-month filing window and hold a separate allowance for re-evaluation, remediation, and on-site work beyond the standard renewal reference.

Tips for reconciling the result with a quotation

Keep the official certification fee separate from design, consulting, and accessibility remediation.
Align every quotation on a before-VAT or VAT-inclusive basis before comparison.
Use the official filed total floor area or regional area rather than adjusting an amount below a band boundary.
Budget preliminary and final certification separately because preliminary approval does not waive the final fee.
Obtain a trip-specific quotation when island airfare or ferry travel can arise.
Treat a reduction as a sensitivity case until the accepting body confirms it.
Confirm re-evaluation and separate filing for an extension, reconstruction, use change, design change, or multiple buildings.
Remember that construction needed to pass the accessibility review is outside the official fee.

Frequently asked questions

Does preliminary certification reduce the final certification fee?

No. Attached Table 8 sets separate preliminary and final fees, so a project completing both stages should budget both.

Can every privately owned building select the 50% non-mandatory reduction?

No. A privately developed facility can still be mandatory based on its use and scale, and the provision is discretionary. Confirm both legal status and certification-body treatment.

Is a building of exactly 10,000 m² still in Band 4?

No. Each lower boundary is inclusive, so exactly 10,000 m² enters Band 5 and uses the current 1.5 multiplier.

Can an 80,000 m² region use the first regional fee?

The official regional table begins at 100,000 m². Do not borrow the first amount without direct target and fee confirmation.

Does the official table include VAT?

No. Attached Table 8 expressly states that VAT is separate, so a cash-payment budget normally adds 10% to the net fee.

Can the social-welfare and non-mandatory reductions be stacked?

The notice provides two separate potential 50% treatments but no stacking formula. This calculator applies only one, and a larger reduction requires written confirmation.

Does the social-welfare reduction apply to renewal?

No. Article 4(4) of the notice expressly excludes renewal applications from that treatment.

Does the result include consulting and remediation work?

No. It calculates the official fee and VAT, plus only the confirmed amount that the user enters as an additional outlay.

Future maintenance should therefore verify the current National Law Information Center notice and attached table first, then cross-check the operating body’s practical guidance.

Build a traceable BF certification budget

Enter the target, area, and application stage above, then reconcile the official amount with the accepting certification body’s guidance.
Apply a reduction only after confirmation and keep consulting, drawing revisions, remediation, and island travel as separate quoted items, so the budget remains traceable from preliminary certification through final certification and renewal.
