Milwaukee DNS Permit & Development Center fee combo (MCO 200-33), updated 2026 (source retrieved Sep 1, 2026). The official path is the deck plan-exam plus accessory-structure building permit plus processing fee, with the 1.6% surcharge applied to the plan-exam and building lines.
The fee is a flat amount on the official row. A permit is required on that path.
The low fee is $162.24, the typical fee is $217.10, and the high fee is $253.68. Those bands are the documented 200 sf / 320 sf / 400 sf walks, not valuation bands.
The official typical project value is $12,000. Listed assumed valuations are $8,000 low, $12,000 typical, and $19,200 high.
Valuation is unused for the fee walk; deck square footage drives the building-permit dollars. Plan exam decks is $50 and is included.
Plus 1.6%: $50 × 1.016 = $50.80. Accessory structure building permit is $0.45/sf and is included; at the typical 320 sf that line is $144 before the 1.6%.
Processing fee is $20 and is included; it is not multiplied by 1.6%. Walk the three documented sizes.
200 sf low: plan exam $50 × 1.016 = $50.80; building $0.45/sf × 200 × 1.016 = $91.44; plus processing $20; $50.80 + $91.44 + $20 = $162.24, so the low fee is $162.24. 320 sf typical (16×20): plan exam $50 × 1.016 = $50.80; building $0.45/sf × 320 × 1.016 = $146.304; plus processing $20; $50.80 + $146.304 + $20 = $217.104, listed as the typical fee of $217.10.
400 sf high: plan exam $50 × 1.016 = $50.80; building $0.45/sf × 400 × 1.016 = $182.88; plus processing $20; $50.80 + $182.88 + $20 = $253.68, so the high fee is $253.68. The $217.10 typical is not added on top of the $162.24 low, and the $253.68 high is not added on top of the $217.10 typical.
Deck plan-exam $50 is explicit. Building permit uses accessory >150 sf at $0.45/sf.
16×20 = 320 sf. This note does not invent a fee beyond the official $162.24 / $217.10 / $253.68 totals.
