Washington DC Alteration Permit Cost (2026)
Residential alteration permit fees in Washington, DC, pulled from the DC Department of Buildings (DOB) Building Permit Fee Schedule live page at dob.dc.gov/node/1620346 (captured April 25, 2026). DC uses a four-tier value-based formula for residential alterations and repairs covering kitchen remodels, bathroom remodels, basement finishes, in-kind window replacements (over 15 units), interior renovations, exterior repairs, and most home-improvement permit categories. Tier 1 (under $500 declared value): $33 flat + 10% Enhanced = $36.30 all-in. Tier 2 ($501 - $1,000): $65 flat + 10% Enhanced = $71.50 all-in. Tier 3 ($1,001 - $1 million): $30 base + 2% of declared construction value + 10% Enhanced Fee, plus a separate Green Building Fee of 0.13% of construction value with its own 10% Enhanced. Tier 4 (over $1 million): $10,030 + 1% of value over $1 million + 10% Enhanced + GBF tiered. A $5,000 minor kitchen update runs $150.15 all-in. A $15,000 bathroom remodel runs $384.45. A $30,000 kitchen remodel runs $735.90. A $50,000 full kitchen plus basement finish runs $1,204.50.
This guide covers: Washington, DC residential alteration and repair permit fees under the DOB Building Permit Fee Schedule, captured live on dob.dc.gov on April 25, 2026. Coverage includes the four value-based tiers for the alteration_repair line item that catches kitchen remodels, bathroom remodels, basement finishes, interior renovations, exterior repairs, roof replacements treated as alterations, and most home-improvement permit categories. The universal 10% DOB Enhanced Fee surcharge applies to every tier on every line item. The Green Building Fee adds 0.13% of declared construction value for Tier 3 alterations ($1,001 to $1 million) with its own 10% Enhanced; the GBF jumps to a tiered base + rate structure for Tier 4 over-$1-million alterations.
This guide does NOT cover: Trade permit fees (electrical, plumbing, mechanical/HVAC) for the alteration scope - these are filed separately under DOB Section d Additional Supplemental Permits, each with the 10% Enhanced Fee on top of itemized trade-line pricing; new construction or additions to existing structures (handled by the DC addition permit guide at the cubic-foot rate, not the alteration tier); commercial alterations (the same tier table applies but with different inspection and review processes); historic-district reviews required for alterations on Historic Preservation Office (HPO) registered properties (separate HPRB review process outside the DOB schedule); demolition (filed under the demolition line at $30 + 2% with 10% Enhanced - same base structure as Tier 3 alterations but a separate permit category); raze (full structural razing, priced at $0.02 per cubic foot under a separate line); fees for design review meetings or repeat technical reviews ($71.50 per single-family residential repeat technical review); the cost of materials, labor, or construction itself.
Important - DC bundles plan review into the tier fee: DC does NOT charge a separate building plan review fee for standard residential alterations. The plan review cost is built into the tiered permit fee. Repeat technical reviews (plans rejected and resubmitted) are billed at $71.50 for single-family residential. Most first-pass approvals do not pay this. This is structurally different from Fairfax County (50% plan review on top of the building permit) and Norfolk's tiered plan review fees - DC's bundled plan review is one of the structural reasons DC alterations are cheaper than Fairfax alterations at the same scope.
Note on alteration vs addition classification: DC's alteration_repair tier formula covers work INSIDE the existing building envelope: kitchen remodels, bathroom remodels, basement finishes, interior renovations, exterior repair work that does not add new heated volume. Additions that add new heated volume to the home (mudrooms, sunrooms, family-room extensions, second-story additions) are NOT priced under the alteration tier - they are priced as new construction at $0.03 per cubic foot under the DC addition path. Confirm classification with DOB at intake for any project that has ambiguous scope (rear-wall removal with bump-out, sunroom over existing slab, partial second-story over existing first floor).
A residential alteration permit in Washington, DC is priced under a four-tier value-based formula. Tier 1 (under $500): $33 flat + 10% Enhanced = $36.30 all-in. Tier 2 ($501-$1,000): $65 flat + 10% Enhanced = $71.50 all-in. Tier 3 ($1,001-$1M): $30 base + 2% of declared construction value + 10% Enhanced on building permit, plus Green Building Fee of 0.13% of construction value + 10% Enhanced on GBF. A $5,000 minor kitchen update runs $150.15 all-in ($30 + $100 = $130 BP + $13 Enhanced + $6.50 GBF + $0.65 Enhanced). A $30,000 kitchen remodel runs $735.90 ($30 + $600 = $630 BP + $63 Enhanced + $39 GBF + $3.90 Enhanced). A $50,000 full kitchen + basement finish runs $1,204.50. Tier 4 ($1M+): $10,030 + 1% over $1M + Enhanced + tiered GBF. DC does NOT bill a separate plan review fee for standard residential alterations - plan review is bundled into the tier. Trade permits filed separately under DOB Section d.
- DC residential alterations are priced under a four-tier value-based formula at the alteration_repair line item, distinct from the cubic-foot rate that applies to new construction and additions. The alteration tier covers kitchen remodels, bathroom remodels, basement finishes, interior renovations, and most home-improvement work that does NOT add new heated volume to the building envelope.
- Tier 1 covers very small projects under $500 declared value: $33 flat + 10% Enhanced = $36.30 all-in. Tier 2 covers small projects $501-$1,000: $65 flat + 10% Enhanced = $71.50 all-in. Both tiers are flat-fee with no Green Building Fee component (the GBF threshold begins at $1,001).
- Tier 3 is the workhorse tier for typical residential alterations $1,001 through $1 million. The formula is $30 base + 2% of declared construction value, with 10% Enhanced Fee on the building permit fee. The separate Green Building Fee adds 0.13% of construction value with its own 10% Enhanced. Total effective rate at typical residential scope: approximately 2.59% of declared value (2% building permit rate x 1.10 Enhanced + 0.13% GBF x 1.10 Enhanced + $30 base x 1.10) + the $33 base portion grossed up.
- Tier 4 covers very large alterations over $1 million declared value: $10,030 base + 1% of value over $1 million + 10% Enhanced. The GBF for Tier 4 also tiers up to $1,300 base + 0.0065% above $1M with 10% Enhanced. A $1.5 million whole-home gut renovation runs approximately $10,030 + $5,000 BP = $15,030 + 10% = $16,533 BP, plus $1,300 + $32.50 = $1,332.50 GBF + 10% = $1,465.75 GBF, total approximately $17,998.75. Tier 4 is rarely triggered by individual residential homeowner projects.
- DC does NOT bill a separate building plan review fee for standard residential alterations. Plan review is bundled into the tier fee. Repeat technical reviews (plans rejected and resubmitted) are billed at $71.50 for single-family residential. This is structurally different from Fairfax County (50% plan review on top of building permit), Norfolk's tiered plan review by area, or Virginia Beach's $100 full PR / $25 counter PR. DC's bundled plan review meaningfully reduces alteration permit costs vs Fairfax at every scale.
- Compared to value-based VA jurisdictions: a $30,000 kitchen remodel costs $735.90 in DC, $255.00 in Henrico County ($100 + $150 + 2% levy), $237.62 in Richmond City ($63 + $169.96 + 2% levy), $314.00 in Virginia Beach ($50 + $150 + $100 PR + $10 tech + 2% levy on $200 BP), $152.00 in Norfolk City (flat $100 + $35 PR + $15 + 2% levy on $100), $402.90 in Loudoun County (bundled flat), and $1,377.00 in Fairfax County (3% + 50% PR + 2% levy). DC sits between the cheap value-based Hampton Roads/Richmond MSA jurisdictions and Fairfax's high-cost 3% formula.
- The Green Building Fee of 0.13% is a separate line item on Tier 3 alteration permits. It applies on top of the building permit and is itself subject to the 10% Enhanced Fee. The GBF funds DC green-building initiatives and is not optional. At $30,000 declared value, the GBF adds $39.00 + $3.90 Enhanced = $42.90 to the building permit total. At $100,000 declared value, the GBF adds $130.00 + $13.00 Enhanced = $143.00. The GBF is one of the largest single line items at higher declared values.
- Trade permits (electrical, plumbing, mechanical) are filed SEPARATELY under DOB Section d and are NOT included in the alteration tier. A typical $30,000 kitchen remodel with new circuit work, gas line for range, plumbing for new sink and dishwasher, and HVAC duct adjustment could add $80 to $200 in trade permits on top of the $735.90 tier fee. Each trade permit also carries the 10% Enhanced. Confirm exact line items with DOB at filing.
DC Alteration Permit Fee Components by Tier
DC's residential alteration permit splits into three component lines on Tier 3 (the workhorse tier for typical home-improvement work): the base + percentage building permit fee, the 10% DOB Enhanced Fee applied to the building permit, the Green Building Fee at 0.13% of declared value, and the 10% Enhanced applied separately to the GBF. Tiers 1 and 2 are simpler flat-fee components with no GBF. The breakdown below shows component math at six typical residential alteration scopes.
| Component | $400 minor (Tier 1) | $5k kitchen (Tier 3) | $15k bathroom (Tier 3) | $30k kitchen (Tier 3) | $50k whole-home (Tier 3) |
|---|---|---|---|---|---|
| Base building permit | $33.00 flat | $30 + $100 = $130.00 | $30 + $300 = $330.00 | $30 + $600 = $630.00 | $30 + $1,000 = $1,030.00 |
| 10% Enhanced on building permit | $3.30 | $13.00 | $33.00 | $63.00 | $103.00 |
| Green Building Fee (0.13% of value, Tier 3 only) | N/A (Tier 1) | $6.50 | $19.50 | $39.00 | $65.00 |
| 10% Enhanced on GBF | N/A | $0.65 | $1.95 | $3.90 | $6.50 |
| All-in alteration permit total | $36.30 | $150.15 | $384.45 | $735.90 | $1,204.50 |
Source: DC Department of Buildings Building Permit Fee Schedule, Section a (Building Structures and Equipment), live page on dob.dc.gov/node/1620346 captured April 25, 2026. The alteration_repair tier table shows four declared-value tiers; the 10% Enhanced Fee applies to every line item independently. The Green Building Fee of 0.13% of construction value applies to Tier 3 alterations ($1,001-$1M) and is itself subject to a separate 10% Enhanced Fee. Plan review for standard residential alterations is bundled into the tier fee; DOB does NOT bill a separate plan review fee. Trade permit fees (electrical, plumbing, mechanical) under Section d are filed separately and are not included in this table.
Worked Examples - Real Alteration Projects in DC
The four worked examples below cover typical DC residential alteration scopes from a small repair under $500 (Tier 1) through a $50,000 full kitchen plus basement finish (Tier 3). Trade permits for electrical, plumbing, and mechanical scope are NOT included - they would be filed separately under DOB Section d and add their own itemized line items plus 10% Enhanced on top of the alteration tier fee.
A homeowner files a permit for minor interior drywall repair after a small plumbing leak, replacement of a damaged interior door, and repainting of an affected wall section. No structural, electrical, or plumbing work beyond patch repair. Contractor invoice: $400 (materials + labor for the drywall patch, door, and paint).
- Declared value: $400 (Tier 1, under $500)
- Building permit (Tier 1 flat): $33.00
- 10% Enhanced on building permit: $3.30
- Green Building Fee: N/A (Tier 1)
- Building permit total: $36.30
Note: this is the cheapest priced residential permit in DC. Many minor repairs under $500 in DC do not require a permit at all (cosmetic-only work, replacement of fixtures without scope changes, in-kind window/door replacement of fewer than 15 units). Confirm whether your specific scope requires a permit before filing. If the work needs a permit, $36.30 is the floor.
A homeowner files an alteration permit for a minor kitchen update: replacement of cabinets and countertops, addition of a new pot-filler faucet over the range (which requires a plumbing rough-in), upgraded outlets and undercabinet lighting (which requires electrical work on a new circuit). Contractor invoice: $5,000 (cabinets + counters + minor plumbing + minor electrical, materials and labor).
- Declared value: $5,000 (Tier 3, $1,001-$1M)
- Building permit ($30 + 2% of $5,000): $30 + $100 = $130.00
- 10% Enhanced on building permit: $13.00
- Green Building Fee (0.13% of $5,000): $6.50
- 10% Enhanced on GBF: $0.65
- Building permit total: $150.15
Note: trade permits for the new plumbing rough-in (one fixture - the pot filler) and the electrical work (new circuit for undercabinet lighting and outlets) would be filed separately under DOB Section d. Estimated electrical permit minimum $24.20, plumbing $28.60 = approximately $53 in trade permits on top of the $150.15. Total all-in for the kitchen update: approximately $203. The same project in Fairfax County runs approximately $229.50 ($150 BP + $75 PR + $4.50 levy). DC and Fairfax are roughly comparable for very small alterations under $5,000.
A homeowner files an alteration permit for a full kitchen remodel: complete demolition of existing kitchen, new cabinets and counters, new island with electrical outlet, new dishwasher rough-in, new range with gas line work, undercabinet lighting on a dedicated circuit, new pendant lighting over island, new tile floor, recessed lighting in ceiling, full new electrical panel work to support new circuits, and minor plumbing relocation for the new sink. Contractor invoice: $30,000 (mid-range remodel, full electrical and plumbing scope, no structural changes).
- Declared value: $30,000 (Tier 3, $1,001-$1M)
- Building permit ($30 + 2% of $30,000): $30 + $600 = $630.00
- 10% Enhanced on building permit: $63.00
- Green Building Fee (0.13% of $30,000): $39.00
- 10% Enhanced on GBF: $3.90
- Building permit total: $735.90
Note: trade permits for the full electrical scope (new circuits, panel work, gas line) and plumbing (new sink and dishwasher rough-in) are NOT included in the $735.90. Expect approximately $80-$150 in electrical permit and $50.60-$78.20 in plumbing on top. Total all-in approximately $865-$965 for the building permit + trades. The same $30,000 kitchen remodel costs $1,377 all-in in Fairfax County (3% + 50% PR + 2% levy) and $255 in Henrico County ($100 + $150 + 2% levy). DC sits between Henrico's value-based capped formula and Fairfax's uncapped 3% formula.
A homeowner files an alteration permit covering both a full kitchen remodel and a full basement finish: kitchen as Example 3 plus 700 sq ft of basement finishing with new drywall, framing of two bedrooms and a full bathroom, new electrical (eight circuits for the basement), plumbing rough-in for the bathroom (sink, toilet, shower), HVAC duct extension to basement zone, and finish flooring. Contractor invoice: $50,000 (combined kitchen + basement scope, mid-range finishes).
- Declared value: $50,000 (Tier 3, $1,001-$1M)
- Building permit ($30 + 2% of $50,000): $30 + $1,000 = $1,030.00
- 10% Enhanced on building permit: $103.00
- Green Building Fee (0.13% of $50,000): $65.00
- 10% Enhanced on GBF: $6.50
- Building permit total: $1,204.50
Note: trade permits for the full electrical (eight circuits + panel work), plumbing (three fixtures + rough-ins), and HVAC (basement zone extension) scope are NOT included in the $1,204.50. Expect approximately $200-$350 in combined trade permits on top, for an all-in total of approximately $1,400-$1,550 including trades. The same $50,000 combined alteration in Fairfax County runs $2,295 building permit only ($1,500 + $750 + $45 levy), and approximately $377.40 in Henrico County ($100 + $270 + 2% levy on $370). DC's $1,204.50 is closer to Fairfax at this scale but still meaningfully cheaper because of the bundled plan review.
Calculate Your DC Alteration Permit
DC's four-tier alteration formula is not currently wired as a primary path in the PermitPrice fee calculator UI - the DC calculator support focuses on flat-rate scopes (pool, garage/shed, fence, instant permit, in-kind window replacement under Instant Permit). The Tier 3 formula at $30 + 2% of declared value + 10% Enhanced + 0.13% GBF + 10% Enhanced is straightforward to compute manually: take 2.59% of declared value and add roughly $33 for the base portions, or use the worked examples on this page as a quick reference. Confirm exact pricing with DOB Scout at scout.dob.dc.gov before filing.
DC Tier 3 alteration rule of thumb: at typical residential scope, multiply declared construction value by 2.59% and add approximately $33 base. A $20,000 alteration runs approximately $551.20 ($30 + $400 + $43 + $26 + $2.60 = $501.60 - rule of thumb slightly overstates because of fixed base components, exact calculation always preferred). For declared values under $1,001 use the Tier 1/2 flat fees ($36.30 or $71.50). For declared values over $1 million, use the Tier 4 formula starting at $10,030 base.
Open the Permit Fee CalculatorTrade Permits for Alterations in DC
Residential alterations with electrical, plumbing, or mechanical/HVAC scope require SEPARATE trade permits in DC under DOB Section d (Additional Supplemental Permits). The tier-based alteration permit covers the building permit and bundled plan review only - it does NOT include circuits, fixtures, gas lines, water lines, sprinklers, ductwork, or HVAC equipment installation. Each trade permit is filed separately and carries the 10% DOB Enhanced Fee on top of itemized trade-line pricing.
Electrical permit basics for alterations: Minimum permit fee $22 + 10% Enhanced = $24.20. Outlets/receptacles/switches/fixtures: $20 per 10 (or fraction) + 10%. Lighting fixtures: $8 per 10 + 10%. Service meter up to 200 amp first: $39 + 10% = $42.90 (heavy-up). The Instant Permit Electrical Heavy-Up ($64.90 with Enhanced) covers a typical 200-amp service upgrade. Central AC residential up to 5 ton: $65 first + $26 each additional + 10%. Most kitchen and bath remodel electrical scope falls under the minimum permit fee or low single-digit line items - typically $24.20-$80 in electrical on top of the alteration permit.
Plumbing permit basics for alterations: First fixture $26 + 10% = $28.60. Each additional fixture $20 + 10% = $22.00. Appliance installation first $26 + 10%. Gas conversion or new burner: $50.60 each. Line cap/cut/test: $28.60 each. A typical kitchen remodel with new sink rough-in (one fixture) and dishwasher rough-in (one appliance) runs approximately $50.60-$78.20 in plumbing. A full bathroom remodel with sink + toilet + shower/tub + vent runs approximately $94.60.
Mechanical/HVAC permit basics for alterations: Refrigeration Class E (0-120k BTU, typical residential): $50.60 each (with Enhanced). AC Class D (120-600k BTU, larger residential): $85.60 each. Instant Permit up to 10 ton (typical residential AC/heat pump replacement): $50.60 each. A typical kitchen remodel with minor HVAC adjustment (no new equipment) does not require a mechanical permit; a basement finish with new ducted extension or zoned mini-split adds approximately $50.60. Confirm equipment-class classification with DOB or your HVAC contractor before filing.
DC Alteration Permit Cost vs DMV Neighbors
DC's four-tier value-based formula with the bundled plan review sits structurally between the Hampton Roads / Richmond MSA value-based formulas (which are cheaper at typical residential scope) and Fairfax County's 3% formula with separate plan review (which is more expensive at every scope). The table below compares the all-in alteration permit cost across the verified DMV cluster at three typical residential declared values: $5,000 minor update, $15,000 bathroom remodel, and $30,000 kitchen remodel. Trade permits are excluded across all jurisdictions to keep the comparison apples-to-apples.
| Jurisdiction | Alteration Pricing Method | $5k update | $15k bathroom | $30k kitchen |
|---|---|---|---|---|
| Washington, DC | $30 + 2% + 10% Enhanced + 0.13% GBF + 10% Enhanced | $150.15 | $384.45 | $735.90 |
| Norfolk City | Flat $100 + tiered PR ($35) + $15 + 2% levy | $152.00 | $152.00 | $152.00 |
| Richmond City | $63 + $6.07/$1,000 over $2,000 + 2% levy | $83.13 | $144.75 | $237.62 |
| Henrico County | $100 + $6/$1,000 over $5,000 (cap $680) + 2% levy | $102.00 | $163.20 | $255.00 |
| Virginia Beach | $50 + $5/$1k + $100 PR + $10 tech + 2% levy on BP | $186.50 | $237.50 | $314.00 |
| Loudoun County | Bundled $395 flat + 2% levy | $402.90 | $402.90 | $402.90 |
| Fairfax County | 3% of value + 50% PR + 2% levy | $229.50 | $688.50 | $1,377.00 |
All figures are building permit only - trade permits (electrical, plumbing, mechanical) excluded across all jurisdictions. Norfolk's flat $152 is structurally the cheapest small-alteration jurisdiction in the verified DMV cluster but does not scale with project size - the same fee applies at $1,000 or $30,000 declared value. Richmond's value formula climbs at $6.07 per $1,000 with no cap. Henrico's formula caps at $680 building permit + 2% levy = $693.60 all-in at approximately $101,667 declared value. Virginia Beach includes the $100 full plan review at all alteration scopes. Loudoun bundles plan review and zoning permit into the $395 flat for alterations under 1,000 sq ft. Fairfax adds 50% plan review on every building permit. Chesterfield County is NOT in this comparison because Chesterfield's residential fee schedule does not include a verified general-alteration line item in PermitPrice's source data - confirm with Chesterfield Building Inspection at (804) 748-1057 for alteration-specific pricing. Source-age caveats: Loudoun is July 2022; Norfolk is July 2021; Richmond is June 2022. Verify all figures with the respective building department.
