SEC EDGAR Company Search & Filing Archive

SEC EDGAR company search and filing archive data is the Multi-Family Residential REITs catalog's primary-document record: EDGAR, the U.S. Securities and Exchange Commission's electronic filing archive, covering every disclosure filed by listed apartment REITs and searchable by company, ticker or full text. Six issuers anchor the multifamily cohort - Equity Residential, AvalonBay Communities, Mid-America Apartment Communities, UDR, Essex Property Trust and Camden Property Trust - and each carries the full filing trail: annual 10-Ks with property-level schedules, 10-Q quarterlies, 8-K current reports, DEF 14A proxies, S-3 and S-11 registration statements, and Forms 3, 4 and 5 insider transactions.

For anyone modeling apartments the pitch is blunt: audited disclosures and standardized financial facts sit in one registry keyed by Central Index Key, so the sector's evidence base arrives assembled rather than hunted down issuer by issuer.

Three shapes arrive in one pull: submission index rows, extracted XBRL facts, and the ticker-to-CIK reference spine:

entity : Vivmark Residential (CIK 0000906107)   formerly Equity Residential / ERP Operating LP
form   : 10-K        filed : 2026-02-13     period : 2025-12-31
accession : 0001193125-26-051433            document : eqr-20251231.htm

form   : 10-K        filed : 2025-02-13     period : 2024-12-31
accession : 0000950170-25-019894            document : eqr-20241231.htm

us-gaap concept : Revenues                  period : 2020-01-01 to 2020-03-31
value  : 682329000    fy : 2020    fp : Q1    form : 10-Q    frame : CY2020Q1

ticker : AVB    cik : 915912    title : AVALONBAY COMMUNITIES INC
ticker : CPT    cik : 906345    title : CAMDEN PROPERTY TRUST

Eleven consecutive 10-Ks reaching back to 2015 were confirmed for that one CIK, with 1,006 recent filings indexed inline - the archive routinely runs deeper than any single screen shows, which is precisely why it rewards a defined slice over a casual scroll.

Thirteen documented fields carry every submission row and extracted fact, each exemplified in the table below. Full-text-search hit attributes and the filing documents themselves sit outside the standard pull, so they fold under additional fields on request.

• Geography: every SEC-registered domestic and foreign filer, including each US-listed multifamily or apartment REIT - the whole cohort resolves through one ticker-to-CIK reference map holding 10,387 registered tickers.
• Temporal: filings from EDGAR's mid-1990s launch through today. Roughly the last 1,000 filings per issuer surface in the standard pull; older filings remain reachable through paginated archive indexes.
• Granularity: two layers - whole documents per filing, and individual XBRL facts per quarterly or annual period, each stamped with value, period start and end, fiscal year and form.

API, files, or your warehouse. Daily, weekly, or hourly.

Every delivery ships the complete field dictionary above, the sample rows and the coverage profile mapped to your scope - no integration archaeology on your side.

1. REIT investors and quants anchor models in primary documents: 10-K property schedules feed occupancy and portfolio analyses, while XBRL revenues and net income drop straight into screens - 593 us-gaap concepts were verified for a single issuer.
2. Competitive-intel teams at rental platforms track insider Form 4 activity, proxy compensation and 8-K announcements across the multifamily cohort without hand-assembling filings issuer by issuer.
3. Investor-relations and capital-markets teams benchmark their own disclosure cadence and structure against peers', placing any metric against every filer for the same period - CY2025Q1 revenues alone returned 1,934 facts across companies.
4. Journalists and academics cite accession-numbered primary sources rather than secondhand summaries, with full-text search narrowing hits to multifamily-specific language.

Notes worth having in hand:

• One registry, every form type - 10-Ks with property schedules, 10-Qs, 8-Ks, DEF 14A proxies, S-3 and S-11 registration statements and Forms 3, 4 and 5 all hang off one searchable registry.
• Numbers beside the paper - standardized facts arrive as typed values with period stamps, so rebuilding an income statement needs no document parsing.
• The CIK spine - the 10,387-ticker reference map ties this archive into quote feeds and financial datasets without guesswork.
• Peer-scale aggregation - one concept aggregated across all filers for a calendar period yields instant benchmarks.

Where this set stops, neighbors pick up: Nareit's Residential REIT sector page adds association-level performance context, Yahoo Finance quote and historical pages carry market pricing, and the same EDGAR machinery applied to another sector shows how the slice scales.
