How Much a Deck Permit Costs Depends on the Fee Model Your Office Uses

Search how much a deck permit costs and you land on a single number. That number cannot exist honestly: we read and classified the deck permit fee note for 137 jurisdictions, and they are not answering the same question. The largest group prices the deck like a piece of construction with a value. Others charge one flat number, a rate tied to the deck’s own square footage, or a mix that resists either. Some publish nothing you can quote at all. Averaging across those is combining incompatible math and reporting the result as one answer.

This piece is about that math, not whether you need a permit at all. The 30 inch deck rule and the four-part exemption test already cover when a deck triggers a permit. Here we assume it does, and ask what the office bills you once it has.

Five groups, hand-classified, not counted by keyword

A script that counts feeNote text for “valuation” or “per square foot” gets this wrong: a dollar-per-square-foot figure often sets the value a fee is computed from, not the fee itself, and a note using neither word can still describe a real, fixed number. Every one of the 137 rows was read individually and sorted by hand into one of five groups, each with a literal quote from that row tied to the call.

Flat fee: the same number no matter the deck

Twenty-three jurisdictions charge one number, or a short set of fixed numbers by size or plan type.

Aurora, Colorado’s flat-rate fee schedule is built around one promise, printed on the form itself: “SAME PROJECT TYPE = SAME PERMIT FEE.” Under that promise, “Single Family Residential Deck” prices at “$402 EACH.” The form adds a separate note that “you must still provide building material costs so the city can accurately estimate city use and county taxes.”

Rochester, New York’s fee page calls its own numbers “fee guideline tables to estimate costs,” and directs anyone who needs the authoritative figure to the online City Code. With that caveat: “Deck up to 144 sq. ft.” is $75, “Deck 145–400 sq. ft.” is $160, and “Deck over 400 sq. ft.” is $235. The same page carries a notice that its fees “will change effective July 1, 2026,” a date already past when we read it today; the guideline figures above are what the page states regardless.

Valuation table: fees built from a construction value

Sixty-two jurisdictions, the largest group, price the deck from a table or percentage keyed to a construction value. Several first derive that value from the deck’s own area through a published table, the way Contra Costa County values a deck at “$25.13 per square foot” before running that figure through its permit-fee table.

Denver, Colorado’s Development Fees page runs a table headed “Valuation of Work / Permit Fee / Plan Review Fee”: work valued “$1.00 to $500.00” is a flat “$20.00” permit fee with no plan review charge, “$501.00 to $2,000.00” is “$35.00,” and from “$2,001.00 to $25,000.00” the permit fee adds “$8.00 for each additional $1,000.00,” with plan review now “50%” of the permit fee.

Cincinnati, Ohio prices any “NEW CONSTRUCTION - ADDITION - ALTERATION - REPAIR,” a category that is not deck-specific: a $2,000 valuation is “$106.00” for a permit filed without plans or “$173.00” for an “RCO Project with plans,” plus a separate, non-refundable “RCO Applications” processing fee of “$49.00.” Five surcharges apply on top, by their own separate rules, not one blanket one: a “1% State Surcharge added to RCO permits as required,” a “3% Technology Surcharge,” a “1% Financial Recovery Fee,” and a “1% Training Surcharge,” each “added to all scheduled fees excluding Administrative Hearings fees,” plus a “5% Planning Surcharge on all Construction, Plumbing and HVAC permits.” A deck permit is a scheduled Construction fee, so all five reach it: 1 + 3 + 1 + 1 + 5 is 11 percent, or about $19, on the $173 base.

Cobb County, Georgia’s building permit fee is a table by construction cost: “Up to $15,000” is “$80.00,” rising through “$50,001 - $75,000” at “$450.00,” then “$6.00 per $1,000 of construction cost” above that. The schedule’s own “Find Your Construction Cost” formula builds that cost from area, “Unheated sq. ft total (x) $31.50,” so the $31.50 figure sets a value, it is not a fee. Two flat lines apply on top regardless of bracket: a “Technology Fee” of “$15.00,” and a “Site Plan Review Fee” of “$100.00” that the schedule states applies “to all New Homes, Additions, Decks, Pools, Retaining Walls, and Accessory Structures,” so it is not priced for decks alone.

Per square foot: the fee scales with the deck itself

Fourteen jurisdictions skip the valuation step and charge a rate times the deck’s own area directly.

Corpus Christi, Texas’s fee schedule prices “Residential Construction- New, Remodels, and Additions” (the schedule does not itself name “deck”) at “Plan Review- New construction, additions and remodeling* $0.146 per square foot” and “Building Permit- New Construction, additions and remodels (excludes mechanical, electrical and plumbing)* $0.461 per square foot $146.41/min.” The schedule’s own note says fees marked with an asterisk “are will be assessed a 4.5% surcharge” (its wording, not ours).

Our row files Fairfax County, Virginia’s deck under Section (A), “New Buildings, Additions or Enlargements,” of a schedule that opens with a base fee, “the minimum fee charged for any permit,” of “$141.75” (the same schedule prices some accessory structures under a different section, so confirm the classification with the office). Table 1 sets three residential rates: “$0.28” per square foot for “Type IA, and IB” construction, “$0.22” for “Type IIA, IIIA and IV,” and “$0.15” for “Type IIB, IIIB and VA, VB.” A modest deck may never leave the minimum: at $0.15 per square foot it covers up to about 945 square feet, at $0.28 up to about 506. A 2.0 percent “Code Academy levy” applies on top.

Twenty rows that do not reduce to one number

These rows run two different pricing tracks, scale by something other than area or value, or stack fees that use different mechanisms; forcing either “flat” or “valuation” on them would state a number the schedule does not promise.

Our data files Fort Worth, Texas’s attached-deck permit as residential remodel work under the ordinance’s own “TABLE IA-1,” which scales by “the number of trades required for the project,” not size or value: the column is headed “Minimum Permit Fee,” and the tiers step from “112.50” for one trade to “562.50” for five, on top of a “Permit Application Fee … 31.50” and a “Technology Fee … 16.87” charged on every application.

Eighteen rows give you nothing to quote

Eleven of the 137 jurisdictions carry no fee note in our dataset at all, and seven more have a note that names no deck permit fee: King County’s “14%” is a fee increase and its “$126” an “application screening fee,” and Arlington County’s “2.35 percent” is a charge for paying by card. That is our data gap, not evidence those jurisdictions charge nothing for a deck permit.

Sacramento County, California is one case: the county’s own Fees and Exactions page points to a fee-code page that returned HTTP 403 to an automated request when we tried it again today, exactly as it did when the row was first checked. That is our access failure, not proof the county has no fee.

Clark County, Washington’s own web pages name no number either, pointing only to “Clark County Code Title 6: Application and Service Fees.” Our row does not yet carry what Title 6 actually says: opened live, Table 6.140.030-1, under “3 Residential Permits – Total Valuation,” prices row N, “Simple garage, carport, patio cover or deck,” at “$350.50 (includes issuance and state fee).” That citation belongs in our data, not yet in it, which is exactly the gap this section is about.

What to ask

Ask what decides your number before you ask for it: a construction value (Cincinnati, Cobb County), the deck’s own area (Corpus Christi, Fairfax County), a flat table (Aurora, Rochester), or something else entirely (Fort Worth’s trade count). Each needs different information from you before it can answer.

124 of the 137 locality pages on this site link that jurisdiction’s own fee schedule directly, with the date we last checked it. If your deck may be exempt in the first place, start with the 30 inch rule and the four-part exemption test before you call about a fee you may not owe.
