Everything you need to build, review, or browse on WHOLE.

A field guide to pre-reviewed infill housing in Indianapolis. How the marketplace works, what we look for in an architect, how the City reviews a design, and the vocabulary every audience needs to speak the same language.

For Owners & CDCs.

WHOLE Neighborhoods is a public marketplace of pre-reviewed single-family, duplex, and ADU designs matched to vacant Indianapolis parcels. Every design has already cleared a structured city review — so when you choose one, you skip months of plan review.

The three-step path
  1. 01
    Browse the marketplace

    Filter by neighborhood, typology, square footage, and cost. Save designs you like.

    Open the marketplace
  2. 02
    Request a consultation

    Send a brief to a verified architect with a parcel attached. They reply with feasibility + a fixed fee.

    Browse architects
  3. 03
    Move to expedited review

    Architect files the parcel-specific drawings with the City. Pre-reviewed designs typically clear in 14 days vs. 90+.

Typical cost
$8.4k – $24k
design license

One-time fee paid to the architect for the right to build their pre-reviewed design on one parcel. Larger typologies (duplex, multi-family) sit at the upper end.

Typical timeline
14
days to expedited approval

Compared with 90+ days for a non-pre-reviewed submission. Construction inspection windows are unchanged — they live in Accela.

Owner FAQ.

The architect owns the design. You buy a single-parcel license — the right to build it once on a specific lot. The license is non-transferable.

For Architects.

WHOLE Neighborhoods is a marketplace for licensed architects who want to build durable infill homes at neighborhood scale. You submit pre-reviewed designs once, list them publicly, and the City does plan-review work upfront — so each homeowner contract is fast, predictable, and parcel-specific.

Application & approval
  1. Step 01
    About you & your firm

    Headshot, license number, firm name, tagline, year founded, team size.

  2. Step 02
    Practice

    Service areas, typology specialisations, practice statement (≥300 chars), biography, lifestyle focuses.

  3. Step 03
    Credentials & documents

    AIA / NCARB / LEED credentials, license certificate, E&O insurance, optional portfolio samples.

Median time to approval: 3 business days, end-to-end.

What we look for in approval.

  • Active licensure in Indiana, verifiable against state records.
  • Current E&O insurance covering residential design at ≥ $1M.
  • Demonstrated infill experience — at least one residential project on a lot ≤ 5,000 sq ft within the last 5 years.
  • A coherent practice statement that names a stance, not a service list.
  • No active license discipline in any state.

Design submission checklist.

  • Site plan with setbacks, drives, and easements (1:200 or 1:100)
  • Floor plans for every level (1:50)
  • Two elevations, minimum (front + one side)
  • Section through the longest dimension
  • Material schedule with manufacturer-grade SKUs where applicable
  • Energy compliance narrative (Indiana Residential Code Ch. 11)
  • Three renders: street view, interior living area, kitchen
  • Cost narrative: target build cost ± 12%
  • Six pre-approved typology classification (single_family / duplex / adu / multi_family)
  • Self-attestation: structural, mechanical, and plumbing scopes are within your license envelope or stamped by a partner

How the City reviews.

City Staff at the Department of Metropolitan Development (DMD) review pre-reviewed candidates through Accela — the City's system of record. WHOLE is observational; Accela governs. Reviewers check four classes of compliance:

  1. Zoning — typology against the parcel's overlay (front yard, side yard, lot coverage, height, FAR).
  2. Egress & life safety — IRC chapters R310 / R311.
  3. Energy — Indiana Residential Code Ch. 11.
  4. Form-based overlays — Mass Ave, Mile Square, and historic district guidelines where applicable.

Revenue & payment.

You set the per-parcel license fee for each design (typical range $8k – $24k). WHOLE charges a transparent 10% platform fee on the license, plus a flat $250 consultation handling fee per matched consultation. Funds are held in escrow and released on milestone:

  • 30% when the owner accepts the consultation.
  • 70% when parcel-specific drawings are delivered to Accela.

Receivables show up on /architect/payments with a per-line breakdown and downloadable PDF receipts.

For City Staff.

Accela governs. WHOLE observes. WHOLE Neighborhoods does not write to your records. It mirrors relevant signals — submission counts, review queues, inspection states — into a single editorial surface so DMD staff can spot trends without leaving the system of record.

How the Accela sync works.

A scheduled sync polls Accela every 15 minutes for cases in any stage between Submitted and Issued. The sync writes only into WHOLE's read replica:

  • Case ID and current stage
  • Parcel reference
  • Linked design (if any)
  • Reviewer notes that DMD has marked public

The Sync state is displayed on every case row: Synced, Pending sync, or Sync error. Errors are routed to devops@wholeneighborhoods.org and rarely block governance.

Review SLAs.

Standard review
90 days

Conventional residential submittal.

Expedited (pre-reviewed)
14 days

Matched against a pre-reviewed design.

RFI response window
10 days

Owner / architect response before stale.

The six pre-approved typologies.

WHOLE's catalog is intentionally narrow. Six typologies cover ~92% of Indianapolis infill demand and let DMD invest review time once per typology, not once per project.

Single-family detached
Modest 2-3 BR on standard 50' lot
Stacked duplex
Two units, one upper, one lower
Side-by-side duplex
Two units sharing a center wall
Detached ADU
Backyard cottage, ≤ 800 sq ft
Attached ADU
Above garage or in-law suite
Small multi-family
3-4 units on combined parcels

Recording a code change.

When DMD or City Council passes an ordinance that affects pre-reviewed designs (height limits, lot coverage, energy targets), it must be recorded on WHOLE so affected designs are flagged for resubmission. Platform Admin records the change at /admin/code-changes. WHOLE then notifies every architect whose designs intersect the change.

Civic glossary.

Fifteen terms used across the platform. If you only read one section before a stakeholder meeting, read this one.

Pre-reviewed design
An architectural design that has already cleared a structured city review against zoning, life-safety, and energy code. Buying a license lets you skip 80% of plan review.
Expedited review
Accela's 14-day track for permits using a pre-reviewed design on a verified parcel.
Accela case
The City of Indianapolis's permit record. The system of truth for every project. WHOLE mirrors but never overwrites.
Overlay district
A zoning layer that sits on top of base zoning with additional rules — historic, form-based, environmental, riverfront.
Code change
A formally adopted ordinance or rule change that retroactively affects already-approved designs. Recorded on WHOLE so designs can be flagged or revised.
RFI
Request for Information. A reviewer's question that pauses the review clock until the architect or owner responds.
Consultation
The owner's first formal contact with an architect on WHOLE — a brief, optional parcel, and a request for feasibility and fee.
Permissive zoning
A zoning regime in which a use is allowed by right (no variance, no special exception). Most WHOLE-catalogued designs target permissive zones.
ADU
Accessory Dwelling Unit. A secondary residence on a lot with a primary residence — detached cottage or attached in-law suite.
Typology
The architectural class of a design — single-family, duplex stacked, duplex side-by-side, ADU detached, ADU attached, small multi-family.
Verified architect
A WHOLE network member whose license, E&O insurance, and infill credentials have been confirmed by Platform Admin.
E&O insurance
Errors & Omissions professional liability. Architects must carry at least $1M residential coverage to publish on WHOLE.
Compliance preview
A pre-submittal compliance scorecard generated by WHOLE that shows likely zoning, life-safety, and energy hits before drawings reach DMD.
MBE / WBE / VBE
Minority / Women / Veteran Business Enterprise. Self-attested flags on architect profiles to surface diverse firms in match-making.
CDC
Community Development Corporation. Non-profit developer working block-by-block in a defined neighborhood — a core WHOLE customer.
