Budgeting for a driveway road occupation fee in Korea
A permitted driveway across public road land may create a recurring occupation fee in addition to the original construction costs.
Remembering the initial bill while overlooking annual notices can leave a shop owner or homeowner short of cash.
This calculator connects the permitted area, official prices of adjacent land, billable period, confirmed relief and annual adjustment to a funding plan.
The jurisdiction is South Korea and the rule year is 2026, for one permit and one fiscal year.
The national preset covers a state-managed national road with a driveway classified under item 3 of Appendix 3 to the Enforcement Decree of the Road Act, such as access to a parking facility or service station.
A separate mode supports a confirmed local ordinance using the same monthly proration method.
A calculated fee does not establish a right of access, approval to build a driveway or permission to occupy the road.
Recurring fees versus building-permit costs
The building-permit calculator collects a checked occupation charge as one initial project expense.
This tool instead reconciles recurring driveway assessments and the cash needed before the next due date.
Design, pavement works, kerb alterations and restoration deposits are separate and are not automatically included.
Identify the road authority before selecting a tariff
State-managed national road
Confirm that the national charging provisions in Road Act Article 66 and Decree Article 69 apply.
The annual rate for an Appendix 3 item 3 driveway is 2% of the relevant land price per square metre.
This preset does not cover farm access, temporary construction access, other facility classifications or occupation fees determined through a competitive award.
Local roads and locally managed national roads
A road can be designated a national road while its relevant section is locally managed.
Use the applicable ordinance in that case.
No rate is automatically selected from a place name.
Confirm the annual rate, monthly proration, rounding unit and minimum charging threshold; if the local proration method differs, use the confirmed notice total for budgeting only.
Record the relevant national road office or municipal department in the location memo.
The road number alone does not identify the charging authority; check the issuer of the permit.
Rural roads governed by a different statute, private access payments and river occupation charges are outside this calculator’s scope.
Understand the area and land-price inputs
Use the permitted occupation area
Enter the area in square metres shown on the permit drawing, not just the entrance width.
Do not substitute the building floor area, the entire property area or the area of an adjacent parcel.
If the occupied area has changed, confirm the permit amendment and the date from which the assessment changes.
Use adjacent non-road parcels
Appendix 3 note 2 uses the official individually assessed price of land touching the occupied road portion, excluding road land.
Do not use a purchase price, building valuation or a price estimate.
When more than one parcel touches the occupied portion, apply a weighted average reflecting their respective contact proportions.
Having two parcels does not automatically justify a simple average.
Keep contact weights in the same unit
Use contact lengths or proportions verified with the authority, consistently across all rows.
Mixing metres in one row with percentages in another produces an invalid average.
The calculator divides by the sum of the weights, so they do not have to sum to one hundred.
For a single parcel, weight 1 is sufficient.
A parcel’s total area is not automatically its contact weight; take the drawing to the authority if the contact measurement is unclear.
Formula, billable months and rounding
Calculation sequence
- Weighted price = sum of each parcel price × contact weight / sum of contact weights
- Base annual fee = permitted area × weighted land price × annual rate
- Reduced annual fee = base annual fee × (1 − confirmed final reduction rate)
- Apply annual adjustment, then multiply by billable months / 12
- Round down to the charging unit, apply the minimum threshold and add the confirmed VAT for that period.
For an annual tariff with an assessment period shorter than one year, Appendix 3 note 3 treats each complete month as 1/12 of a year and omits an incomplete month.
Do not simply divide elapsed days by 365 or round remaining days up to a month.
Enter the authority-confirmed number of whole billable months for the fiscal year, from 0 to 12.
Do not combine multiple fiscal years into a single row.
The national preset discards amounts below the KRW 100 unit under note 5.
Decree Article 71(5) does not charge an assessed occupation fee below KRW 10,000.
An amount of 9,999 becomes 9,900 and is not charged; 10,000 is charged; 10,099 becomes 10,000; and 10,100 stays 10,100.
The annual reference is not rounded first and then reused for proration: the period calculation uses the unrounded adjusted annual basis to avoid double rounding.
Enter the final confirmed reduction
Road Act Article 68 and Decree Article 73 provide relief for qualifying residential access, residential quasi-housing and small-business premises.
The corresponding full-housing, residential quasi-housing and small-business reductions are 100%, 50% and 10%, subject to the relevant conditions.
A building name or business registration alone does not establish eligibility.
Select confirmed no reduction separately from unknown reduction status.
Mixed buildings and temporary relief
For a building combining housing with other uses, review the exemption for the occupation area corresponding to the housing share of total floor area.
For residential quasi-housing combined with other uses, the half reduction applies to the corresponding share.
Enter an authority-confirmed final equivalent reduction rate rather than exempting the entire occupation area without verification.
Announcements of temporary 25% small-business relief in 2026 require separate confirmation of eligibility, regular-assessment coverage and interaction with existing relief.
Do not automatically add it to 10% and assume a 35% reduction nationwide.
Do not carry an expired policy into a future year or treat an application as approval.
The annual 10% increase adjustment
Decree Article 69(3) addresses continuous occupation spanning at least two fiscal years when the annual fee calculated under the applicable provisions increases by 10% or more over the annual fee paid for the previous year.
The supported automatic scenario is limited to national rules, unchanged continuous occupation, a complete 12-month assessment and a positive comparable prior annual fee.
It uses the smaller of the annual fee after reduction and 1.1 times the prior paid annual fee.
Use a confirmed annual amount for different circumstances
If the previous notice includes VAT, late charges, installment interest or another permit, do not enter its total as the comparable annual fee.
Confirm the treatment of changed area or use, partial-year occupation, or a prior full exemption.
For local-road adjustments, partial periods or combined relief, enter a confirmed adjusted annual fee.
That amount already reflects reduction and adjustment and is not reduced again.
It can support period budgeting even if the underlying land-price or relief data remain incomplete, provided the annual amount and period rules are confirmed.
Worked fictional examples
Annual budget and monthly saving target
Assume 20 m² of permitted area, adjacent prices of KRW 1,000,000 and 3,000,000 per m², and equal contact weights of 1.
The weighted price is KRW 2,000,000 per m².
At an annual rate of 2%, the base annual fee is KRW 800,000; a confirmed 10% reduction leaves KRW 720,000.
With no annual adjustment, 12 months and a confirmed period VAT amount of KRW 72,000, the total is KRW 792,000.
Funds available of KRW 192,000 leave a KRW 600,000 gap, requiring KRW 50,000 per month over 12 saving months.
The VAT amount is a fictional confirmed input, not a statement that every occupation fee is taxed at the same rate.
Changing period, weights or prior annual fee
Six billable months at the same annual basis produce a fee of KRW 360,000.
A separately confirmed period VAT amount of KRW 36,000 makes the total KRW 396,000; do not reuse the 12-month VAT amount.
Changing the contact weights to 1 and 3 makes the weighted land price KRW 2,500,000 per m².
In the original example, a comparable prior annual fee of KRW 600,000 limits the current 12-month fee to KRW 660,000 when all automatic adjustment conditions are confirmed.
A notice overrides the estimate for budgeting
If the original example has a final notice total of KRW 750,000, budgeting uses that amount and separately displays an estimate-minus-notice difference of KRW 42,000.
The difference does not prove an assessment error or entitlement to a refund.
It identifies a reason to compare the price year, assessed area, reduction period, rounding and tax lines.
Step-by-step use and result interpretation
- Collect the permit, drawing, current notice and prior-year notice, and confirm the authority and road classification.
- Enter the occupation area and the official prices and contact weights of adjacent non-road parcels.
- Select the fiscal-year billable months, final confirmed reduction and annual adjustment method.
- Enter the actual period VAT amount or confirm no VAT; add the notice total if available.
- Enter funds already available and the saving horizon before the due date to see the funding gap and monthly target.
- Save the review sheet, resolve the pending items with the authority and update the inputs.
The annual reference fee is a 12-month amount under the current inputs, excluding VAT and before applying the minimum charging threshold.
The period occupation fee is a separate result after proration, rounding and the minimum rule.
The monthly target divides the remaining funding gap by the saving months and rounds up to a whole won, so accumulated savings may slightly exceed the target.
When funds already cover the budget, the funding gap and monthly target are zero; the payment obligation itself remains.
Practical checks for shop owners and homeowners
Shop operating budget
Set aside recurring fees alongside monthly operating costs.
Check changes in business name, the contractual allocation between landlord and tenant, and the named permit holder separately.
Avoid counting the same fee twice in the owner’s and tenant’s budgets.
Mixed residential and commercial use
Obtain the calculation of the occupation area eligible for residential relief and confirm the final reduction rate.
Do not infer housing or residential quasi-housing status from a shop sign or a building’s informal name.
Ask the authority about period-specific treatment after a change of use.
Regular billing, a temporary permit, the end of occupation and actual restoration may have different dates.
Reducing the period in this tool does not amend a permit or automatically refund an existing assessment.
After closure or lease termination, confirm the actual end of occupation and the required procedure to avoid overlooking later notices.
Frequently asked questions
Can I substitute the purchase price for the official land price?
No.
Confirm the individually assessed prices of adjacent non-road parcels and their reference year.
A confirmed adjusted annual fee or notice total can separately support budgeting.
Can I simply average two adjacent parcel prices?
Only when equal contact proportions have been confirmed.
Use a contact-weighted average and exclude road land.
Does every driveway use the 2% annual rate?
The preset supports only the confirmed Appendix 3 item 3 driveway classification on a state-managed national road.
Check the relevant category or ordinance for other facilities and locally managed national roads.
Is residential access automatically free?
Confirm eligibility and the affected area first.
A mixed-use building requires review of the occupation area corresponding to its residential share.
This calculator does not determine eligibility.
Can I pay in the monthly amounts displayed?
The monthly amount is a savings target.
Under the national rule an annual fee exceeding KRW 500,000 may be charged in up to four installments per year, with interest on the balance and authority confirmation.
Approval and interest are not calculated here.
Can unknown VAT be treated as zero?
Unknown is different from confirmed no VAT.
The estimate total remains pending if VAT is unknown, even when the occupation fee is known.
A confirmed final notice total can still be used to prepare funds.
Will next year’s notice be the same?
Land prices, permitted area, relief and local rules may change.
The annual reference is an amount under current inputs, not a forecast of a future notice.
Does the review sheet require personal identification?
No name or personal identification number is required.
The location memo, authority and calculation inputs are sufficient.
