Brownsburg is one of the fastest-growing suburbs on the west side of Indianapolis, and its neighborhoods are full of homes that are the right age for a deck addition or replacement. If you’re planning to build, expand, or replace a deck in Brownsburg, you’ll need a permit from the Town’s Department of Development Services before any work begins.
This guide walks you through Brownsburg’s permit process step by step — what you need to submit, what the town inspects, and what to know about setbacks, HOA requirements, and Indiana building code before your project gets underway.
Who Handles Deck Permits in Brownsburg?
All building permits in Brownsburg are issued by the Department of Development Services, located at Brownsburg Town Hall. This is the same office that handles planning, zoning, inspections, and code enforcement for the town.

Does Your Deck Need a Permit?
In Brownsburg, a deck is classified as a residential accessory structure. The town requires a Residential Accessory Permit for projects including decks, concrete patios, detached structures of 90 square feet or more, and driveways. If you’re building or significantly modifying a deck, you need a permit — regardless of whether the deck is attached to the house or freestanding.
Permit applications are submitted through the town’s online Development Services Portal. You can apply, upload documents, pay fees, and request inspections without visiting Town Hall in person.
What You Need to Submit
Brownsburg requires a complete set of documents with your permit application. All files must be uploaded in PDF format through the online portal. Here’s what the town expects:
| Document | What It Must Include |
| Site Plan | Drawn to scale (8½×11 or 11×17), showing the deck’s dimensioned location relative to property lines, adjacent structures on the same lot, and widths of any bordering streets or easements |
| Construction / Building Plans | Floor plan with dimensions and overall layout; foundation plan with footing specifications (type, width, depth); framing details with joist/beam sizes, spacing, and connections; elevation view showing height from grade; wall section details if applicable |
| Electrical Plan (if applicable) | Outlet and lighting locations — required only if the deck includes wired lighting, outlets, or similar electrical work |
| HOA Approval Letter | Written approval from your homeowners association — required as part of the application package |
If you’re unsure whether your project needs a permit or what documents apply, you can email a project outline to building@brownsburg.org and a staff member will follow up with the specific requirements.
Setback Rules for Decks
Brownsburg’s Unified Development Ordinance establishes setback requirements that apply to all structures, including decks. The specific setbacks for your lot depend on your zoning district and subdivision plat — setback lines established on a recorded plat take precedence over the general ordinance standards.
As a general guideline, Indiana’s standard allowances for unroofed decks apply in Brownsburg: an unroofed deck or patio that is no more than 3 feet 6 inches above the ground (excluding railings) may extend up to 5 feet into a required front yard, 10 feet into a required rear yard, and 3 feet into a required side yard. However, it may not extend closer than 1 foot to any lot line.
Before finalizing your deck design, confirm your lot’s specific setbacks with Development Services. Corner lots, through lots, and lots in newer planned developments may have different requirements than standard interior lots.
Indiana Building Code Requirements for Decks
Brownsburg follows the 2020 Indiana Residential Code, which mirrors the International Residential Code (IRC) with state-level modifications. Here are the key structural requirements that apply to residential deck construction:
| Requirement | Standard |
| Footings | Must extend below the frost line — 36 inches deep in central Indiana |
| Guardrails | Required on any deck surface more than 30 inches above grade; minimum height is 36 inches (some jurisdictions require 42 inches) |
| Baluster Spacing | Openings in guardrails must not allow passage of a 4-inch sphere |
| Stair Treads | Minimum 10-inch tread depth |
| Stair Risers | Maximum 7¾-inch rise; must be consistent within ⅜ inch across all steps |
| Ledger Board | Must be properly flashed and through-bolted or lag-screwed to the house framing per IRC Table R507.9.1.3 |
| Handrails | Required on at least one side of stairs with four or more risers; must be graspable (1¼” to 2” diameter) |
Your contractor should be familiar with all of these standards, but it helps to know them yourself — especially if you’re comparing bids or reviewing a design proposal.
HOA Approval — Required in Brownsburg
This is one detail that catches homeowners off guard: Brownsburg requires an HOA approval letter as part of your permit application. Most of Brownsburg’s residential neighborhoods are governed by homeowners associations, and the town expects you to clear your project with your HOA before submitting for a building permit.
HOA architectural review can take anywhere from a few days to several weeks depending on your community’s review cycle. Start this process early — a delayed HOA approval holds up your entire permit timeline. Common HOA requirements for decks include restrictions on materials, colors, maximum height, railing style, and whether the deck can be visible from the street.
If your property is not part of an HOA, note that on your application and the town will process it accordingly.
Inspections
Once your permit is issued, inspections are required at key stages of construction. You must schedule each inspection at least two business days in advance through the online portal. Priority is given to requests submitted online rather than by phone.
Typical inspection stages for a deck project include:
- Footing inspection — after holes are dug but before concrete is poured, to verify depth and placement
- Framing inspection — after the structural frame is complete but before decking boards are installed, to check joist sizing, spacing, connections, and ledger attachment
- Final inspection — after the deck is fully completed, to verify guardrails, stairs, fasteners, and overall code compliance
When the final inspection passes, the town issues a Certificate of Occupancy. Keep this document — it may be needed when selling the home, refinancing, or filing insurance claims. Permits expire one year after issuance if no inspections have been scheduled, and expired permits can create problems during a title search.
What Happens If You Build Without a Permit?
Building a deck without a permit in Brownsburg creates real problems. Unpermitted work can result in fines, required demolition, or a stop-work order. It also surfaces during property sales when a title company runs a search for outstanding issues. If you’ve already started or completed work without a permit, contact Development Services at (317) 852-1128 to discuss your options — an after-the-fact permit may be available, though it typically involves additional fees and inspections.
Planning Your Deck in Brownsburg
Brownsburg’s mix of established and newer neighborhoods means deck projects range from simple platform replacements on homes built in the 1990s to multi-level composite builds in recently developed subdivisions. A few planning considerations specific to this area:
- Lot sizes vary widely. Older neighborhoods near downtown Brownsburg tend to have smaller lots with tighter setbacks. Newer developments along the 267 corridor and the south side of town typically offer larger rear yards with more room to work with.
- Drainage matters. Brownsburg’s stormwater management ordinance applies to all construction. Your site plan should account for how runoff from the deck area is directed — particularly if the lot slopes toward a neighbor’s property or a drainage easement.
- Material choice affects long-term costs. The Hendricks County climate delivers the same freeze-thaw stress as the rest of central Indiana. If you’re weighing pressure-treated wood against composite options, understanding how local weather patterns impact different decking materials can help you make a more informed decision.
