Zoning, HOAs & Historic Districts in the Indianapolis Metro (IN)

1. Indianapolis-Marion County's consolidated "Unigov"

In 1970, the Indiana General Assembly merged most of Indianapolis's city government with Marion County government into a single "Consolidated City" — commonly called Unigov — under one mayor and a City-County Council, expanding Indianapolis's jurisdictional footprint from about 82 to 402 square miles and its population from roughly 480,000 to 740,000 overnight. Unigov unified road maintenance, zoning, natural-resource management, flood control, and the tax base across most of the county. It did not unify everything, though: schools were explicitly excluded and Marion County still has 11 separate public school districts today; police stayed separate until 2005, when the Indianapolis Metropolitan Police Department (IMPD) was formed by merging city police with the county sheriff's department; and fire service is still split — five outer townships merged into the Indianapolis Fire Department starting in 2007, but Decatur, Pike, and Wayne townships still run their own independent township fire departments. Nine townships and roughly a dozen small "included towns" also continued as their own units of local government. Sources: Encyclopedia of Indianapolis, "Structure of Unigov"; Wikipedia, "Unigov."

2. The excluded cities: Lawrence, Speedway & more

As a compromise to reduce opposition to the 1970 merger, any already-incorporated Marion County municipality with a population over 5,000 was exempted from full consolidation — four cities cleared that bar: Beech Grove, Lawrence, Speedway, and Southport (Southport reportedly annexed extra territory just before Unigov took effect specifically to clear the threshold). Two of them — Lawrence and Speedway — get their own neighborhood guides on this site precisely because they function as genuinely separate places: excluded cities elect their own mayors and councils, run their own police departments, and hold their own zoning and planning authority rather than falling under the Indianapolis/Marion County plan commission. They still pay countywide taxes, receive countywide services in areas that weren't devolved, and their residents vote for both their own local officials and the consolidated city's mayor and City-County Council. We could not find granular, department-by-department detail on exactly how services like fire protection are split for Beech Grove and Southport specifically, and flag that as unconfirmed rather than guessing. Cumberland is set to become a fifth excluded city — House Bill 1131, signed by Governor Mike Braun on June 24, 2025, grants it excluded-city status effective January 1, 2027, the first community to leave Unigov's full-merger structure since 1970, driven mainly by frustration that Cumberland-area development projects currently need sign-off from both the town and Indianapolis; fire protection will continue through the Indianapolis Fire Department under the enacted bill. Reported figures on the fiscal impact to Indianapolis conflict — one outlet cited roughly $38,000/year in property tax revenue affected, another cited roughly $847,000/year — and we're flagging that conflict rather than picking a number.

3. Townships: a narrower, but still-real layer of government

Township government in Indiana lost its assessment role in most places starting in 2008: under Indiana Code 36-6-5-1, any township with fewer than 15,000 parcels as of January 1, 2008 had its assessment duties shifted to the county assessor, and only larger townships could keep an elected assessor after a local referendum. We couldn't confirm from public sources whether any of Marion County's townships currently retain that exception. What townships still do, and do actively: Marion County's nine townships (Center, Decatur, Franklin, Lawrence, Perry, Pike, Warren, Washington, and Wayne) each elect a trustee who administers "township assistance" — emergency help with rent, utilities, food, clothing, medical costs, and transportation to work for qualifying residents — the modern descendant of historic township poor relief. A January 2025 report by the Greater Indianapolis Multifaith Alliance found real access problems in this system: only 3 of the 9 townships offered walk-in appointments, and some approved as few as 13-16% of applicants. Decatur, Pike, and Wayne townships also still run independent fire departments (Section 1). Two 2026 bills — House Bill 1315 and Senate Bill 270 — would force smaller townships statewide to merge with a municipality or county by 2028, but both explicitly exempt Marion County, so its nine townships aren't currently at risk of elimination.

4. Indiana's Homeowners Association Act

Indiana HOAs are governed by the Homeowners Association Act, Indiana Code Title 32, Article 25.5, which traces to House Bill 1071 in the 2009 legislative session and applies core governance provisions to associations regardless of when they formed. It covers board meetings (members generally have a right to attend; a board may close a meeting only to discuss delinquent assessments or pending litigation; 10% of members can force a special meeting), records access (members can request contracts, invoices, bills, and board minutes in writing), assessment liens (a separate statute, IC Title 32, Article 28, Chapter 14, requires a notarized lien statement; an HOA lien has no super-priority — it sits behind property tax liens and a first mortgage — and a foreclosure-sale buyer isn't liable for assessments that came due before the transfer), and foreclosure (Indiana requires judicial foreclosure only — no non-judicial power of sale — and a lien not enforced within 5 years of recording is void). A wave of new HOA legislation takes effect July 1, 2026: House Enrolled Act 1115 requires at least four days' written notice and an agenda for board meetings, lets virtual attendance count toward quorum, gives HOAs statutory fining authority conditioned on a published fine schedule and advance notice, and eliminates the ability to charge for document inspection or copying entirely; HEA 1150 protects display of the U.S. and Indiana flag and bars an association from discriminating against a vehicle or home equipment based on its fuel source (so an HOA can't specifically ban EVs, or conversely gas equipment); and HEA 1152 lowers the no-quorum annual budget-increase cap from 110% to 105% for newly formed associations.

5. The Indianapolis Historic Preservation Commission's districts

The Indianapolis Historic Preservation Commission (IHPC), created in 1967 and strengthened several times since (Lockerbie Square became its first designated district in 1968; the commission was reorganized to nine members in 1982), now operates under the city's Department of Metropolitan Development. Within an IHPC-designated local historic district or conservation area, exterior renovation, new construction, demolition, or significant site work requires a binding Certificate of Appropriateness — a real, enforceable design-review requirement distinct from Indianapolis's separate 19 honorific National Register of Historic Places districts, which carry no such local review. Sources differ slightly on the exact current count of local historic districts (12, 13, or 14 depending on the source), but they agree on the roster and on 5 conservation districts (Cottage Home, Cumberland, Fayette Street, New Augusta, and Ransom Place); named local historic districts include Lockerbie Square, Old Northside, Fletcher Place, Chatham Arch, Fountain Square, Massachusetts Avenue, Irvington, Herron-Morton Place, the Wholesale District, Woodruff Place, Monument Circle, St. Joseph, Lockefield Gardens, and the Indiana World War Memorial Plaza. Two of this guide's own neighborhoods — Fountain Square and Lockerbie Square — sit inside IHPC-designated districts themselves, meaning exterior changes there go through the Certificate of Appropriateness process rather than standard permitting alone.

6. Zoning & historic character in the metro's other cities

Outside Indianapolis's own IHPC and Unigov-era zoning, this metro's other cities each run their own planning authority. Carmel has its own Planning & Zoning Office and is known for its walkable Arts & Design District in Old Town and for the HOA-governed, New Urbanist-style Village of West Clay. Fishers runs its own Planning & Zoning Department, including a specialized development code for its downtown Nickel Plate District. Noblesville has several National Register historic districts, including the Noblesville Commercial Historic District (listed 1991), though we found no confirmed local commission with binding design-review authority there — worth a direct check if that matters for a specific property. Westfield, one of the fastest-growing communities in the state (roughly 9,300 residents in 2000 to an estimated 58,400 by 2023), is anchored by the Grand Park Sports Campus and has the honorific, National Register-listed Union High Academy Historic District. Zionsville's brick-paved Main Street runs through "the Village," and the town introduced an ordinance in 2022 to create its own Historic Preservation Commission — we found evidence the ordinance passed a first reading and the commission met, but couldn't confirm final adoption or whether it currently holds binding design-review authority, so treat that as unresolved. Greenwood runs its own Planning Department and Advisory Plan Commission, was reported in early 2025 to be overhauling its Unified Development Ordinance, and has the honorific Greenwood Commercial Historic District (National Register, 1991). Brownsburg and Avon both maintain their own planning departments; we did not find a confirmed historic district or notable HOA-heavy master-planned community for either in this pass — a gap in what we could confirm, not a negative finding.

7. A pending statewide zoning shake-up: HEA 1001 (2026)

Worth knowing if you're weighing future density near a specific property anywhere in this metro: House Enrolled Act 1001, a statewide housing and zoning law, was signed by Governor Mike Braun in early March 2026 (reporting on the exact date varies slightly; confirm against the Indiana General Assembly's own bill-history page if the date matters to you). It requires every local government in Indiana — meaning Indianapolis and every one of this metro's other cities and towns — to hold a public hearing by January 1, 2027 reviewing its own zoning code specifically through a housing-production lens: whether to allow duplexes, triplexes, or fourplexes in single-family zones, permit accessory dwelling units, allow adaptive reuse of commercial buildings into housing, increase density, or reduce lot sizes, setbacks, and parking minimums. In its final, narrowed form, the law also makes certain housing types — duplexes, ADUs, and commercial-to-residential conversions — "by-right" permitted uses that can skip discretionary zoning hearings near transit corridors, in riverfront redevelopment projects, and in designated redevelopment areas, unless a local government affirmatively opts out by a stated deadline (reported as December 31, 2026 in some coverage — we could not independently confirm this exact date against the bill's enrolled text). A companion law, HEA 1210, separately preempts local ordinances that cap or restrict residential rentals. Builders and business groups supported the final package; local officials, mayors, and county commissioners in the affected cities largely opposed it as state override of local zoning authority. As of this research (September 2026), which of this metro's cities and towns will opt in, opt out, or adopt their own version of these housing allowances is genuinely unresolved — worth tracking through each city's own council or plan-commission agenda over the rest of 2026.

8. How we keep this page current

Unigov's structure (Section 1) and the excluded cities' basic status (Section 2) are settled, decades-old facts, though Cumberland's pending 2027 transition is genuinely in motion and its exact fiscal impact is a real, unresolved conflict in our sources. Township government (Section 3) and Indiana HOA law (Section 4) are stable but see incremental legislative changes most years — the July 2026 HOA amendments in Section 4 are worth re-checking once they've been in effect a while. The historic-district roster in Section 5 comes from the city's own Encyclopedia of Indianapolis-sourced material and IHPC's public records, though the exact current district count has minor source disagreement. Section 7's HEA 1001 rollout is the single most fluid item on this page — every city and town in this metro has a hearing deadline of January 1, 2027, and outcomes weren't yet known as of this writing. If you spot something on this page that's changed, or notice a broken link, we'd like to know — see our contact information.
