Do I need a permit to build a deck in Greenwood?

Yes, if the deck is over 200 square feet or attached to the house. Decks under 200 square feet with ground-level framing may be exempt. Footings must reach 36 inches below finished grade. Call the Building Department if your deck is small or low — they can tell you in 60 seconds if you're exempt. If you need a permit, it's typically same-day over-the-counter approval.

How deep do deck footings need to be in Greenwood?

36 inches below finished grade, measured to the bottom of the footing. This is Greenwood's frost-depth standard and appears in the state building code. You'll add 12 inches of compacted gravel or stone for bearing, so you're looking at roughly 4 feet of hole. The footing inspector will measure — don't assume you can get away with 24 inches.

Can I pull a building permit myself if I own the house?

Yes. Greenwood allows owner-builder permits for owner-occupied residential work. You become the permit-holder and responsible party. You'll file in person at City Hall, sign the permit, and be present for inspections. Some trades — particularly electrical and HVAC — may require a licensed contractor to sign off on the work. Ask the Building Department at the time of filing which trades require a licensed signature.

How much do permits cost in Greenwood?

Greenwood typically charges a base fee plus a percentage of project valuation. Deck and fence permits are often flat-fee ($75–150). Electrical and HVAC permits run $50–200 depending on scope. Larger projects (additions, full remodels) cost 1–2% of project valuation with a minimum fee. Ask the Building Department for a fee quote when you call; they can give you a ballpark based on your scope.

How long does plan review take in Greenwood?

Over-the-counter permits (decks, simple fences, water heaters, electrical subpermits on straightforward work) are approved same-day or next business day. Larger projects with structural design, stormwater review, or HVAC ductwork changes take 2–4 weeks. Stormwater review (if your lot is in a managed drainage area) can add 1–2 weeks. Ask the Building Department for an estimate when you file.

What happens if I skip a permit and build anyway?

You risk a stop-work order, fines, and having to tear down the work or bring it into compliance after the fact — which is more expensive and disruptive than getting the permit first. A future sale, insurance claim, or neighbor complaint can surface unpermitted work and create liability. Greenwood's enforcement is not aggressive, but the risk is not worth it. Permits are cheap insurance.

Does Greenwood have an online permit portal?

No. As of this writing, Greenwood does not offer online permit filing. You file in person at City Hall during business hours (Monday–Friday, 8 AM–5 PM). Bring two copies of your application, site plan, and any relevant drawings (floor plan, deck framing, electrical schematic). The staff are efficient; most routine permits are over-the-counter approvals.

Do I need a permit in Greenwood, Indiana?

Greenwood is a Johnson County suburb south of Indianapolis with fast residential growth and a straightforward approach to permitting. The Building Department enforces the 2020 Indiana Building Code (which mirrors the 2021 IBC) with local amendments focused on stormwater management and setbacks in the city's expanding neighborhoods. Most single-family permit work — decks, fences, room additions, electrical upgrades, HVAC replacement — requires a permit. The key question for most homeowners isn't whether a permit exists; it's whether your specific project crosses the threshold that triggers one.

Greenwood's frost depth is 36 inches, which sets deck-footing and foundation requirements throughout the city. The soil is glacial till with karst terrain to the south, which affects drainage and sometimes triggers additional engineering for basements or large additions. The city allows owner-builder permitting for owner-occupied residential work, meaning you can pull permits yourself without hiring a contractor — though you'll be the permit-holder and responsible party on the job.

This guide covers the most common projects, the rules that govern them, and what to expect from the Building Department. If you're unsure whether your project needs a permit, a five-minute phone call to the Building Department removes all doubt — and it's the safest move before you buy materials or hire labor.

What's specific to Greenwood permits

Greenwood uses the 2020 Indiana Building Code, which aligns with the 2021 IBC. The city has adopted all standard residential sections (IRC R101 through R410) without major deviations, but adds local amendments on drainage, grading, and subdivision setbacks. When in doubt, assume the IRC standard applies — but always confirm with the Building Department for local tweaks, especially if your property is near a detention basin or in a newer subdivision with specific stormwater requirements.

Deck footings must bottom out at 36 inches below finished grade in Greenwood. That means if you're building a 12×16 attached deck, your footings go 4 feet deep (36 inches frost + 12 inches of gravel bearing). Many homeowners skip this step or dig only 24 inches — the footing inspection will catch that and require a do-over. Plan for the full 36-inch depth from the start.

Drainage and grading get close scrutiny in Greenwood, especially in newer subdivisions where stormwater management plans are in place. Any addition, driveway expansion, or grading change may trigger a stormwater review. The Building Department can tell you in one phone call whether your lot is in a managed drainage area and what that means for your project. This rarely stops a project, but it can add 1-2 weeks to plan review and cost $100-300 for additional engineering.

Greenwood does not currently offer fully online permit filing as of this writing. You file permits in person at City Hall during business hours (typically Monday–Friday, 8 AM to 5 PM). Bring two copies of your site plan, floor plan (for interior work), or deck framing plan, along with the completed permit application. The Building Department staff are efficient: most routine permits (fences, decks under 200 square feet, water-heater swaps) are over-the-counter same-day approvals. Larger projects enter formal plan review and take 2–4 weeks.

Owner-builder permits are allowed for owner-occupied residential work, which means you can pull permits on your own home without hiring a general contractor. You become the permit-holder and responsible party — you're the one who must be present for inspections and sign off on code compliance. Electrical and HVAC subpermits may still require a licensed electrician or HVAC contractor signature, depending on the work. Ask the Building Department at the time of filing which trades require licensed-contractor sign-off.

Most common Greenwood permit projects

These are the projects that bring most homeowners to the Building Department. Each has its own threshold, fee structure, and inspection sequence.

Decks

Attached and detached residential decks over 200 square feet require a permit in Greenwood. Footings must reach 36 inches below finished grade. Most deck permits are over-the-counter approvals with footings, ledger, and framing inspections.

Fences

Residential fences over 6 feet in rear and side yards, or any fence in a corner-lot sight triangle, require a permit. Pool barriers always require a permit regardless of height. Most fence permits are issued same-day.

Electrical work

Any permanent electrical work (circuits, outlets, panel upgrade, hardwired appliances) requires a subpermit filed by a licensed electrician. Owner-builders can often handle lower-complexity work, but verify with the Building Department.

Room additions

Any addition that expands the conditioned footprint of the home requires a full permit with structural, electrical, and mechanical plan review. Plan 3–4 weeks for review. Stormwater review may add another week if the lot is in a managed drainage area.

Basement finishing

Finished basements require a permit when you're adding egress windows, changing ceiling height, or installing a second means of egress. Egress wells must meet IRC R310.1 dimensions. Plan review takes 2–3 weeks.
