Washington DC Pool Permit Cost (2026)
Swimming pool permit fees in Washington, DC, pulled directly from the live DC Department of Buildings (DOB) Building Permit Fee Schedule on dob.dc.gov/node/1620346 (captured April 25, 2026). DC uses flat-fee pricing for residential pools by size, not by declared construction value: a pool up to 15,000 gallons is $260 base, and a pool over 15,000 gallons adds $33 for each additional 1,000 gallons of capacity. Every DOB line item also carries the universal 10% Enhanced Fee. The result for a standard residential pool: $286.00 all-in for the building permit. Plumbing fixtures (pool fill line, drain, equalizer) and electrical work (pool grounding, lighting circuits, equipment service) are filed as separate trade permits under the DC schedule and priced per fixture or circuit. DC does not bill a separate plan review fee for residential pool permits - the flat fee covers it.
This guide covers: Washington, DC residential swimming pool building permit fees as published in the DOB Building Permit Fee Schedule on dob.dc.gov/node/1620346 (Section a, Swimming Pool line items). Coverage includes the up-to-15,000-gallon flat fee ($260 + 10% Enhanced = $286.00), the over-15,000-gallon formula ($260 + $33 per additional 1,000 gallons + 10%), the absence of a separate plan review line for residential pool permits, the trade permit structure (electrical pool grounding, lighting circuits, and plumbing fixtures filed under the DC trade permit schedules), and how a pool permit interacts with DC's universal 10% Enhanced Fee and Green Building Fee programs.
This guide does NOT cover: Commercial swimming pool permits (separate scope under the DOB commercial alteration tiers); the District of Columbia Department of Health licensing or operating permits for public/community pools; zoning approvals required before permit submission (lot coverage, rear-yard requirements, ANC neighborhood consultations, historic preservation review for Capitol Hill or Georgetown properties); the DOOH (DC Office of Planning) special permits for properties in historic districts; the DC Department of Energy and Environment (DOEE) Stormwater Management Plan review if the pool installation triggers a Major Land-Disturbing Activity threshold; pool barrier (safety fence) permits if the existing yard fence does not meet the DC Construction Code requirements; or any costs from the pool installation contractor (excavation, shell, decking, equipment, labor).
Note on portable wading pools: The DC DOB Building Permit Fee Schedule does not publish a depth threshold for permit exemption, but the DC Construction Code and the International Swimming Pool and Spa Code generally exempt portable wading pools (typically under 24 inches deep, designed to be drained and stored) from building permit requirements. Anything deeper, more permanent, or with a circulation system requires the pool permit. Confirm with DOB Customer Service at 202-671-3500 before purchase.
Note on the universal 10% Enhanced Fee: Every DC DOB fee line carries a 10% Enhanced Fee on top, identified in the DOB schedule as the column "Enhanced Fee." The pool permit's $260 base becomes $286.00 with Enhanced. The trade permits you file separately (electrical, plumbing, mechanical) also carry their own 10% Enhanced on each fee line.
A Washington DC swimming pool building permit for a pool up to 15,000 gallons costs $286.00 all-in: $260 base from the DOB Building Permit Fee Schedule plus the universal 10% Enhanced Fee. There is no separate plan review fee for residential pool permits - the flat fee covers it. A larger 22,000-gallon pool costs $540.10 ($260 base + 7 x $33 for the 7,000 gallons over the 15,000-gallon threshold = $491, plus 10% Enhanced). Plumbing and electrical trade permits are filed separately. A pool with the minimum electrical permit (pool grounding via instant permit) and one plumbing fixture adds roughly $50.60 in trade permit fees on top of the building permit.
- DC uses size-based, not value-based, pricing for residential swimming pool permits. A $25,000 fiberglass shell and a $90,000 gunite build with the same water capacity pay the same DOB permit fee. The construction value you write on the application changes only the contractor scope, not the city permit fee.
- Pools up to 15,000 gallons: $260 + 10% Enhanced Fee = $286.00 flat. This covers most typical residential in-ground and above-ground pools (a 16 x 32 foot rectangular pool at average depth is roughly 13,000-15,000 gallons).
- Pools over 15,000 gallons: $260 + $33 for each additional 1,000 gallons + 10% Enhanced. A 25,000-gallon pool (10,000 gallons over the threshold) costs $260 + 10 x $33 = $590, + 10% Enhanced = $649.00 all-in.
- DC does NOT bill a separate plan review fee for residential pool permits. The DOB Plan Review Structure section explicitly states the plan review cost is built into the tiered or flat-rate permit fee. The only plan-review-related fee that may apply is the Repeat Technical Review at $71.50 if your plans are rejected and resubmitted.
- Trade permits are required and priced separately. Electrical pool grounding is itemized on the DC trade permit schedule (Section d). Plumbing fixtures (pool fill line, drain, equalizer) are $26 first fixture + 10% = $28.60, then $22 each additional. An Instant Permit option exists for limited-scope electrical work at $22 each (with Enhanced) - which can cover simple pool electrical scopes.
- No filing deposit applies to DC pool permits. The DOB filing deposit (50% of assessed permit fee, max $20,000) applies only to new construction and additions, not flat-rate pool permits.
- DC's pool permit price is mid-pack across the DMV region. At $286.00 it sits between Norfolk City ($192.50 flat) and Loudoun County (bundled $402.90). Fairfax County charges $413.10 for the same standard pool because Fairfax adds a 50% plan review surcharge on top of its $270 flat pool fee. See the DC vs Fairfax comparison for full math across decks, alterations, and pools.
- The DOB Building Permit Fee Schedule is a live page on dob.dc.gov (not a dated PDF). PermitPrice captured the page state on April 25, 2026 and re-verifies quarterly. DOB updates the page when the DC Council adopts new fees; verify current rates with DOB Customer Service at 202-671-3500 before filing.
DC Pool Permit Fee Components
A DC pool building permit is built from two components only: the base flat fee (size-driven) and the universal 10% Enhanced Fee. There is no separate plan review fee for residential pools. There is no state levy in DC (the 2% Virginia state levy that applies to all VA permits does not apply in the District of Columbia). The Green Building Fee, which applies to alterations and new construction, does not apply to flat-fee pool permits.
| Component | Pool up to 15,000 gal | Pool 25,000 gal (10,000 over) |
|---|---|---|
| Base building permit fee | $260.00 flat | $590.00 ($260 + 10 x $33) |
| 10% Enhanced Fee | $26.00 | $59.00 |
| Separate plan review | $0 (built in) | $0 (built in) |
| State levy | $0 (DC, not VA) | $0 (DC, not VA) |
| All-in building permit total | $286.00 | $649.00 |

Live page on dob.dc.gov captured April 25, 2026. The above-15,000-gallon formula is published as $260 base + $33 per additional 1,000 gallons; PermitPrice applies the 10% Enhanced Fee per DOB schedule convention.
Worked Examples - Real Pool Projects in DC
Each example shows arithmetic from the same DC DOB fee schedule. DC's pool fee is driven by gallon capacity, not declared construction value. The same $286.00 building permit applies whether your 14,000-gallon plunge pool cost $30,000 to install or $75,000.
A homeowner installs a 16 x 32 foot fiberglass in-ground pool with an average depth of 4 feet (approximately 14,000 gallons). The pool is under the 15,000-gallon threshold so it uses the flat-rate line.
- Base building permit fee: $260.00 flat (pool up to 15,000 gallons)
- 10% Enhanced Fee on $260: $26.00
- Separate plan review: $0.00 (built into the flat fee)
- Total building permit: $286.00
Note: this $286.00 covers the building permit only. Trade permits (electrical pool grounding and lighting circuits, plumbing fixtures for fill and drain) are filed separately and priced per unit. Budget an additional $50-$150 in trade permits depending on installer scope.
A homeowner installs an 18 x 40 foot gunite in-ground pool with an average depth of 5 feet (approximately 25,000 gallons). The pool is 10,000 gallons over the 15,000-gallon threshold.
- Base building permit fee: $260.00
- Additional gallons surcharge (10 x $33): $330.00
- Subtotal: $590.00
- 10% Enhanced Fee on $590: $59.00
- Total building permit: $649.00
Note: DOB requires the actual filled water capacity at normal operating level for the gallon-count line. A pool builder's spec sheet typically lists the water-volume figure; if not, the DC inspector calculates from pool dimensions during plan review.
The same 14,000-gallon in-ground pool from Example 1, this time including the typical electrical and plumbing trade permits a residential pool requires. Trade permit totals depend on the actual scope your contractor files; this example uses minimums from the DC trade permit schedules.
Building permit (from Example 1): $286.00
Electrical permit (pool grounding + 1 lighting circuit via Instant Permit):
- Instant Permit electrical (general scope): $22.00 each with Enhanced
- Per-circuit lighting fee approximation: included in instant permit scope
- Subtotal (estimate): $22.00 (minimum; full electrical scope with multiple circuits priced higher under Section d Group 1-7)
Plumbing permit (2 fixtures - pool fill line and drain):
- First plumbing fixture: $26.00 + 10% = $28.60
- Each additional fixture (1 x $22 + 10%): $22.00
- Subtotal: $50.60
Combined permit total (estimate): $358.60
Estimate caveat: the electrical and plumbing trade permit lines depend on actual project scope. If your installer is adding multiple new circuits (pool pump, salt cell, heater, lighting), each circuit is itemized under Section d Group 1-7 of the DOB schedule (outlets/fixtures $20 per 10 with Enhanced; service meter 0-200 amp $39 first with Enhanced). If a gas pool heater is installed, mechanical trade permits add to the total. Treat the trade permit subtotals here as floor estimates from the DC schedule, not final invoiced amounts. Your installer's permit application is the source of truth.
Calculate Your DC Pool Permit
The PermitPrice fee calculator supports DC pools up to 15,000 gallons directly as a flat-rate project. Pools over 15,000 gallons currently route to the DC jurisdiction page for the size-based formula, since the cost-only input field cannot accept a gallon count without a separate UI surface. Pick "Washington, DC" and "Swimming Pool" in the calculator dropdowns for the standard $286.00 flat building permit fee.
Calculator coverage for DC pools: pool up to 15,000 gallons returns $286.00 flat (the same regardless of declared construction value). For pools over 15,000 gallons or unusual installations, see the full DC permit fee page for the formula and worked examples.
Open the Permit Fee CalculatorTrade permits (electrical pool grounding, plumbing fill/drain) are not modeled in the calculator and should be priced from the DC trade permit schedules with your installer.
Trade Permits DC Requires for Pools
A residential pool installation in DC almost always pulls additional electrical and plumbing trade permits beyond the building permit. These are billed under separate DC schedules (DOB Section d, Additional Supplemental Permits) with their own per-unit fees and the same 10% Enhanced Fee. Your pool installer typically pulls these on your behalf, but the costs land on the homeowner.
| Trade Permit Component | DC Fee | When It Applies |
|---|---|---|
| Electrical Instant Permit (general) | $22.00 each (with Enhanced) | Limited-scope electrical work eligible under DOB's Instant Permit program. Pool grounding for a single residential pool can often be filed this way. |
| Outlets / fixtures (10 or fraction) | $20 per 10 + 10% Enhanced | If electrical exceeds Instant Permit scope, outlets and fixtures bill per 10 (or fraction). A pool lighting + pump + salt cell circuit set typically falls under one or two 10-fixture groups. |
| Service meter 0-200 amp (first) | $39.00 + 10% Enhanced | If a sub-panel or new service is added for pool equipment. Each additional meter $16 + 10%. |
| Plumbing fixture (first) | $26.00 + 10% = $28.60 | Pool fill line, drain, equalizer count as separate fixtures. |
| Plumbing fixture (each additional) | $20.00 + 10% = $22.00 | Each additional fixture beyond the first. |
| Gas line cap/cut/test (each) | $28.60 each | If a gas-fired pool heater is installed. Gas line cap/cut/test billed separately. |
| Mechanical Instant Permit (up to 10 ton) | $50.60 each | If a heat-pump pool heater up to 10 ton is installed, eligible for Instant Permit treatment. |
| Universal 10% Enhanced Fee | Applied to every trade fee line | The Enhanced Fee column adds 10% to every base fee in the DOB schedule. Built into the figures shown above. |

DC Pool Permit Cost vs DMV Neighbors
DC's $286.00 flat pool permit sits in the middle of the DMV pricing range for a typical 30,000-dollar residential in-ground pool. Most Virginia jurisdictions price pools either via percent-of-value formulas (which scale with the declared pool cost) or via dedicated flat fees. DC's gallon-based pricing decouples permit cost from project value entirely - the same fee applies whether the contractor scope is $30,000 or $80,000.
| Jurisdiction | Pool Pricing Method | Standard Pool All-In |
|---|---|---|
| Washington, DC | $260 + 10% (size-based) | $286.00 |
| Norfolk City | $125 flat + $50 PR + $15 + 2% levy | $192.50 |
| Henrico County | $100 + $6/$1,000 over $5,000 | $255.00 |
| Richmond City | % of construction value | ~$237.62 |
| Virginia Beach City | $50 + $5/$1,000 of value | $314.00 |
| Fairfax County | $270 flat + 50% PR + 2% levy | $413.10 |
| Loudoun County | Bundled $395 + 2% levy | $402.90 |
"Standard pool all-in" assumes a typical residential in-ground pool of $30,000 declared value or up to 15,000 gallons (where size-based pricing applies in DC). All-in totals include the building permit fee, plan review (where charged separately), jurisdiction processing/technology fee, and the 2% Virginia state levy (does not apply in DC). Trade permits (electrical pool grounding, plumbing) are excluded because they vary by installer scope. Loudoun and Richmond figures carry source-age caveats as published on those jurisdiction pages.
