Deck Permit in Indianapolis, Indiana
It depends
Sometimes, depending on the project
Before building a deck that stands 18 inches or more above grade, which needs an improvement location permit, and before building one where any part of the floor is more than 30 inches above finished grade, which needs a structural permit as well.

Quick answer
Indianapolis runs a deck through two separate permits and the answer changes twice. A deck less than 18 inches above grade level is a Minor Residential Feature and is on the improvement location permit exemption list, so it needs no permit. A deck 18 inches or more above grade is a Minor Residential Structure and requires an improvement location permit. A structural permit is separately required once any part of the deck floor is more than 30 inches above finished grade, since Sec. 536-201(b)(15) exempts only a deck where "No part of the floor is more than thirty (30) inches above finished grade" and where the contractor or owner complies with the county assessor notification requirement of Sec. 536-215.
Typical threshold: deck height above grade, excluding handrails, at which an improvement location permit becomes required.

What a deck permit costs in Indianapolis
How to apply in Indianapolis
A residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- A permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- A scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- A deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- A section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
Deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Indianapolis permit portal or by phone at 317.327.8700.

Deck height above grade, excluding handrails, at which an improvement location permit becomes required. Always confirm with the office before starting.
- How much does a deck permit cost in Indianapolis?
- DBNS Fee Schedule (Permits, as of 1.5.2026): Improvement Location Permit - Residential (ILP), "Single-family Accessory Buildings and Additions," $32.00 per application plus $108.00. If a structural permit is also required, Structural Permit - Residential (STR), "Construction or placement of, or additions to, accessory Class 2 structure": $40.00 per application, review fee $150.00 for 1,000 sq ft or less plus $25.00 per additional 500 sq ft, issuance fee $300.00 (the schedule prints the range 200 - 1,000 sq ft). See the official fee schedule for current amounts.
- How long does a deck permit take in Indianapolis?
- DBNS target for initial review is 10 business days for remodels, additions and similar residential projects. Times can vary by workload and project scope, so confirm with the office.
- Where do you apply for a deck permit in Indianapolis?
- You can apply through the Indianapolis permit portal or contact the City of Indianapolis Department of Business and Neighborhood Services (DBNS) directly. The links are listed on this page.
- Can a homeowner pull a deck permit themselves in Indianapolis?
- Under Indiana law (IC 36-7-8-3(a); IC 36-7-8-3(d); IC 25-28.5-1-11; IC 25-28.5-1-32(5)): Indiana is unusually permissive toward the homeowner doing the work. IC 36-7-8-3(d) provides that a county building standards ordinance adopted under that section does not apply to private homes that are built by individuals and used for their own occupancy, although the onsite sewage system still must comply with state law. That exemption is narrow: it reaches county ordinances for unincorporated areas under IC 36-7-8, not a city or town permit ordinance, so a homeowner inside municipal limits still answers to the local building department. On the trades, Indiana licenses plumbers at the state level but exempts the homeowner: IC 25-28.5-1-11 makes it unlawful to act as a plumbing contractor or journeyman plumber without a state license, while IC 25-28.5-1-32(5) excludes the owner occupant of a dwelling of eight or fewer residential units who is installing, altering, or repairing the plumbing system. Electricians are not licensed by the state at all: Indiana Code Title 25, which houses the professions and occupations licensing chapters, contains no electrician licensing chapter, and IC 36-7-8-3(a) instead lets a county adopt electrical standards by ordinance, so electrical licensing in Indiana is a local matter. Confirm how Indianapolis applies this before you apply.
