Reference tableFee transparency12 min readRental Junk Fee Laws by State: The 2026 All-In Rent Table for Apartment and Multifamily OperatorsAs of October 22, 2026, Colorado, Connecticut, Massachusetts and Minnesota require advertised apartment rent to carry mandatory fees, each with different exclusions. Illinois adds listing disclosure and a fee ban for leases from January 1, 2027. New York City requires listings to disclose tenant-paid fees, and the FTC treats omitting mandatory fees as deceptive.Read the guide FrameworkFair housing12 min readFair Housing Advertising Rules for Apartments and Multifamily Communities: Federal, State and City (2026)42 U.S.C. 3604(c) and 24 CFR 100.75 bar any apartment ad, notice or statement indicating a preference based on race, color, religion, sex, disability, familial status or national origin. States and cities add classes such as source of income, age and marital status, so one phrase can be lawful in Texas and a violation in New York.Read the guide ExplainerAccessibility12 min readADA Website Compliance for Apartment and Multifamily Websites: What the Law Requires in 2026Yes, in practice. The Justice Department treats a rental office as a public accommodation under ADA Title III, and courts apply Title III to websites that connect renters to that office. No federal rule sets a technical standard for private housing sites, so WCAG 2.1 Level AA is the working benchmark, and 2.2 AA is the safer build target.Read the guide Original researchListing accuracy10 min readApartment Listing Accuracy Report: Nearly 9 in 10 Multifamily Communities Describe Themselves Differently Across Listing SitesApartment listings are inaccurate far more often than operators assume. In a Brynson analysis of 6,000 communities and 1.6 million units, nearly 89% described themselves differently depending on which listing site a renter visited. Although 97% of listings had been updated within the previous 90 days, conflicting mandatory fees, missing amenities and contradictory terms persisted.Read the guide ExplainerILS strategy10 min readILS Management for Apartments and Multifamily: The Operator's Guide to Internet Listing ServicesAn internet listing service (ILS) is a rental marketplace such as Apartments.com, Zillow, Apartment List or Zumper where apartment communities advertise units, rents, fees and photos. Operators usually feed listings from their PMS, pay by subscription package, per lease or per listing, and should judge each ILS at each property by its cost per signed lease.Read the guide FrameworkCompliance operations11 min readProperty Management Compliance Software for Multifamily: A Buyer's Map of the Five Categories for Apartment OperatorsProperty management compliance software for multifamily falls into five categories: affordable housing certification (LIHTC, HUD, USDA), building and safety violation tracking, vendor insurance (COI) tracking, leasing and fair housing process workflow, and digital advertising compliance. The fifth checks what renters see: advertised fees, fair housing language, website accessibility, listing accuracy and photos. Only that one reads the published page.Read the guide

Fee Transparency and Advertised Rent

Which apartment fees must appear in advertised rent, where they must appear and under which law: FTC, all-in pricing states and city rules, each linked to its primary source.

Illinois adds listing disclosure and a fee ban for leases from January 1, 2027. New York City requires listings to disclose tenant-paid fees, and the FTC treats omitting mandatory fees as deceptive.Read the guide Checklist9 min readFee Transparency Compliance Checklist for Apartment Listings: A Multifamily Audit TemplateA fee transparency audit compares every place a property advertises price (website, floor plans, unit pages, map, fee guide, application flow, each ILS) with the PMS fee schedule and the rules at that address. A surface passes only if its total monthly price includes every mandatory recurring fee, is the most prominent price, matches the PMS and appears before payment.Read the guide Explainer8 min readFTC Junk Fee Rules for Rental Housing: What the Greystar Order and 2026 Rulemaking Mean for Apartment OperatorsThere is no final FTC rule on apartment fees yet. The FTC treats advertised rent that leaves out mandatory fees as deceptive under Section 5 of the FTC Act, settled with Greystar for $24 million in December 2025, and opened a rental housing fee rulemaking in March 2026. Comments closed April 13, 2026, and no proposed rule has been published.Read the guide Reference table12 min readWhich Apartment Fees Must Be Included in Advertised Rent? A Fee-by-Fee Guide for Multifamily OperatorsMandatory recurring fees such as trash, valet trash, pest control, technology, package and amenity fees generally belong in the advertised monthly rent under all-in rules and the FTC's Greystar order. Optional fees, contingent fees such as late, pet or transfer fees, and utilities billed at actual cost can usually sit beside the rent, clearly labelled.Read the guide Explainer9 min readDoes California SB 478 Apply to Apartments? The Honest Pricing Law and Multifamily Advertised RentSB 478 does not name apartments. It added Civil Code 1770(a)(29) to the Consumers Legal Remedies Act, in force since July 1, 2024, banning advertised prices that leave out mandatory fees other than government taxes and shipping. Whether the CLRA reaches residential leases is unsettled, so the conservative course is to price advertised rent as if it does.Read the guide How-to10 min readNYC FARE Act Requirements for Apartment Landlords and Multifamily Operators: Listing Disclosures, Fee Records and the Proposed All-In RuleThe NYC FARE Act (Local Law 119 of 2024), in effect since June 11, 2025, stops landlords passing their own broker's fee to tenants. Every listing must clearly disclose all fees a tenant must pay, and the tenant signs an itemized fee disclosure before the lease, which the landlord keeps for three years.Read the guide Explainer9 min readApartment Admin Fees: What They Cover, Where They Are Restricted and How Multifamily Operators Disclose ThemAn apartment admin fee is a one-time charge for processing a new lease, separate from the application fee and the security deposit. No federal law bans it, but the FTC's Greystar order sets the benchmark: disclose it before taking any payment. California treats it as security, Massachusetts bars it at move-in, and Illinois restricts related lease fees.Read the guide

Fair Housing Advertising

What apartment ads, ILS listings, websites and paid social may say, and whom they may target, when protected classes change by state and city.

Framework12 min readFair Housing Advertising Rules for Apartments and Multifamily Communities: Federal, State and City (2026)42 U.S.C. 3604(c) and 24 CFR 100.75 bar any apartment ad, notice or statement indicating a preference based on race, color, religion, sex, disability, familial status or national origin. States and cities add classes such as source of income, age and marital status, so one phrase can be lawful in Texas and a violation in New York.Read the guide Reference table11 min readFair Housing Words and Phrases to Avoid in Apartment Listings, With Compliant RewritesAvoid words that describe who should live in an apartment rather than the apartment: "no kids", "adults only", "perfect for young professionals", "Christian community", "no wheelchairs" and, where source of income is protected, "no Section 8". Describe the units, amenities, rent and policies instead, and check each phrase against the property's state and city classes.Read the guide Reference table12 min readSource of Income Discrimination Laws by State: Can Apartment Ads Say 'No Section 8'?Federal fair housing law does not protect source of income, but PRRAC's March 2026 compilation lists 21 states and territories, including DC and Guam, with statewide laws, plus many cities and counties. Where those laws cover vouchers and advertising, as in California, New York, Washington and Michigan, writing "no Section 8" in an apartment ad is itself a violation.Read the guide Checklist11 min readFair Housing Advertising Checklist for Apartment and Multifamily Marketing Teams (Free Template)A fair housing advertising checklist for apartments tests every channel (ILS listings, website, Google and Meta ads, social, email and text, signage and phone scripts) for words and images that indicate a preference based on a protected class. It checks each property's state and city classes, paid-ad settings and logo use, and records reviewer, date, change and evidence.Read the guide Comparison11 min readFacebook (Meta) and Google Housing Ad Rules for Apartment Marketers: Special Ad Category and Targeting LimitsApartment ads on Meta must run in the Housing special ad category: ages 18 to 65+, all genders, a 15-mile minimum radius, and no ZIP codes, lookalikes or exclusions. Google bars age, gender, parental status, marital status and ZIP targeting for US housing ads. Neither makes an ad lawful; copy and audiences still fall under the Fair Housing Act.Read the guide How-to11 min readAI Apartment Listing Descriptions and Fair Housing: Risks, Guardrail Prompts and a Multifamily Review WorkflowAI writers echo old listings and your brief, so they add lines like "ideal for a student" or "the landmark church" that describe who should live there. You still publish the ad. Give the model a fact sheet, not a pitch, add the property's state and city classes to the prompt, and have a person approve every draft.Read the guide Reference table12 min readFair Housing Protected Classes by State and City: A Reference for Apartment and Multifamily AdvertisingThe Fair Housing Act protects seven classes nationwide: race, color, religion, sex, disability, familial status and national origin. Most large rental states add more. Of the 16 states we checked, 13 add classes such as age, marital status, sexual orientation, gender identity, military status or source of income, and cities like New York and DC add many more.Read the guide Explainer9 min readHow to Advertise 55+ and Active Adult Apartments Under Fair Housing RulesAdvertise a qualifying community as housing for persons 55 or older, in those words. HUD's rule at 24 CFR 100.306(b) says phrases like "adult living" or "adult community" are not consistent with 55+ intent. The exemption lifts familial status rules only, so disability, race, religion and state age protections still govern every ad, photo and audience.Read the guide

Apartment Website Accessibility

How ADA rules reach property websites and rental applications, which WCAG level to meet, and what to do about overlays, vendors and demand letters.

All 8 guides Compliance360 Web Accessibility
Explainer12 min readADA Website Compliance for Apartment and Multifamily Websites: What the Law Requires in 2026Yes, in practice. The Justice Department treats a rental office as a public accommodation under ADA Title III, and courts apply Title III to websites that connect renters to that office. No federal rule sets a technical standard for private housing sites, so WCAG 2.1 Level AA is the working benchmark, and 2.2 AA is the safer build target.Read the guide Checklist12 min readApartment Website Accessibility Checklist: WCAG 2.1 AA for Every Multifamily Page TypeCheck an apartment website page type by page type against WCAG 2.1 AA: gallery photos and floor plans need text alternatives, unit maps, tour schedulers and chat must work by keyboard, application fields need labels and readable errors, and text needs 4.5:1 contrast. Automated tools catch only part of WCAG, so mark which items a person must verify.Read the guide How-to9 min readADA Accessibility for Online Rental Applications: Fixing Barriers in the Apartment and Multifamily Leasing FlowTreat the online application as the highest-risk page on a property site: it is where an applicant is either let in or turned away. Test every step against WCAG 2.1 AA (2.2 AA is the safer target), make your vendor show its conformance report, and publish a phone, in-person and accommodation route on the apply page.Read the guide Explainer9 min readAccessibility Overlays and Widgets on Apartment Websites: Do They Make a Multifamily Site ADA Compliant?No. A widget or overlay script does not by itself make an apartment website conform to WCAG. In April 2025 the FTC finalised an order requiring accessiBe to pay $1 million and barring it from claiming, without competent evidence, that its automated tool can make any website WCAG compliant. Conformance comes from fixing the site's own code and re-testing it.Read the guide Reference table12 min readWCAG 2.2 for Apartment and Multifamily Websites: The New Criteria Mapped to Maps, Floor Plans and ApplicationsWCAG 2.2, published by W3C on October 5, 2023, keeps every WCAG 2.1 criterion except the obsolete 4.1.1 Parsing and adds nine new ones, six at Level A or AA. On apartment websites they hit sticky tour bars and chat bubbles that hide focus, draggable maps and sliders, small gallery controls, repeated application fields and portal logins.Read the guide How-to9 min readApartment Website ADA Lawsuits and Demand Letters: What Multifamily Operators Should DoDo not ignore it, and do not edit the site first. Send the letter to counsel the day it arrives, preserve how the cited pages looked and worked, reproduce each barrier, then check every property on the same template. Federal website accessibility suits rose 27% to 3,117 in 2025, led by New York, Florida and Illinois.Read the guide Comparison9 min readWebsite Accessibility Tools for Property Management Companies: Compliance360 and Point Tools Compared for MultifamilyA property management company needs a tool that tests every property site and the rental application against a chosen WCAG level, explains each fix, re-scans after releases and keeps a dated record. Compliance360 does this beside fee, listing and fair housing checks. For accessibility alone, WAVE, axe, Pope Tech and Siteimprove are strong options.Read the guide How-to9 min readAlt Text for Apartment Photos, Floor Plans and Unit Maps: Accessible Media Patterns for Multifamily WebsitesWrite alt text for apartment photos that says what a renter would learn from the image, in one short sentence, with no "photo of" and no keyword lists. Mark purely decorative images alt="". Give every floor plan a text summary, every pricing grid a real data table, every interactive unit map a list view and every tour a transcript.Read the guide

A Guide for Multifamily OperatorsOn its text, California AB 723 (Business and Professions Code 10140.8, in effect since January 1, 2026) covers digitally altered images in advertising for the sale of real property by brokers, salespeople or people acting for them. It never mentions leases or rentals. Rental photos are still exposed: BPC 17500 and 17530 bar misleading real estate advertising by any person.Read the guide Checklist8 min readILS Listing Audit for Apartments and Multifamily: Why Listings Drift, What ILS SEO Really Controls and a Field-by-Field ChecklistFor apartment communities, ILS SEO is mostly data. Paid packages buy prominence, and listing sites do not publish how they rank. What you control is whether every field your PMS sends (rent, fees, availability, lease terms, pets, amenities, floor plans, photos) is complete and identical on every site. Audit field by field, fix in the PMS, verify next sync.Read the guide Checklist9 min readVirtual Staging and Listing Photo Policy Template for Apartment and Multifamily CommunitiesA virtual staging policy for an apartment community sorts every edit into three tiers: allowed without a label (lighting, color, cropping), allowed with a label and the original nearby (staging, added or removed furniture), and prohibited (features the unit lacks). It also covers model units, renderings, originals, refresh dates and who signs off.Read the guide Comparison9 min readHow to Tell If Apartment Listing Photos Are AI Generated or Virtually Staged: Tools Compared for Multifamily TeamsThere are two ways to check an apartment listing photo. AI detectors such as Hive and Sightengine return a probability that an image is synthetic. Comparison tools register the published photo against your original and show what changed. Disclosure rules ask what changed, so multifamily teams need the original on file, not only a score.Read the guide

Explainer10 min readILS Management for Apartments and Multifamily: The Operator's Guide to Internet Listing ServicesAn internet listing service (ILS) is a rental marketplace such as Apartments.com, Zillow, Apartment List or Zumper where apartment communities advertise units, rents, fees and photos. Operators usually feed listings from their PMS, pay by subscription package, per lease or per listing, and should judge each ILS at each property by its cost per signed lease.Read the guide Reference table12 min readILS Syndication for Apartments, Mapped: Where Zillow, Apartments.com, Apartment List and Zumper Multifamily Listings Appear (2026)ILS syndication means one listing contract puts your apartment community on several sites. Zillow's 25-plus-unit listings also appear on Trulia, HotPads, Realtor.com and the Redfin sites; Apartments.com runs a CoStar network of sister sites; Zumper names PadMapper, Bing, Realtor.com and ChatGPT. A stipulated FTC order filed August 2026 keeps Zillow syndicating to Redfin.Read the guide How-to8 min readPosting Rentals on Zillow for Apartment Communities: The 25-Unit Multifamily Rule, PMS Feeds and Blocked ListingsZillow treats any rental property with 25 or more units as a large multifamily listing that requires a paid listing. Smaller rentals can be posted free in Zillow Rental Manager, but apartment communities advertise through a paid agreement, usually fed from the PMS. Send each property from one source only, or Zillow is likely to decline the second version.Read the guide How-to9 min readCost Per Lease by Source for Apartments and Multifamily: How to Calculate It Honestly, With a Worked ExampleCost per lease by source is what you paid one listing source in a period divided by the signed leases attributed to that source in the same period. To make it honest, count only months with complete invoices, match leases by property and month, treat fewer than three leases as low confidence, and compare against your portfolio rate.Read the guide Comparison9 min readApartments.com Advertising Cost and ILS Pricing for Multifamily: How Zillow, Apartments.com, Apartment List and Zumper ChargeILSs bill apartment communities three ways: fixed monthly subscriptions priced by properties advertised and placement (Apartments.com), pay per lease (Apartment List, billed from your move-in reports; Zillow also sells one), and per-listing plans (Zumper, $4 to $10 per listing a month). Community rates are mostly quoted privately, so compare offers on cost per lease.Read the guide Checklist8 min readHow to Audit ILS Spend Across an Apartment and Multifamily Portfolio: A 30-Day ChecklistAn ILS audit takes about 30 days: list every contract and package by property and listing site, reconcile invoices against what you bought, check pay-per-lease charges against PMS move-ins, compare each property's cost per lease with the portfolio rate, and spot check listings. The output is a short, approved list of package changes per property.Read the guide Framework8 min readWhat Is the Best ILS for Multifamily? How Apartment Operators Choose Listing Sites by Market, Stage and Cost Per LeaseThere is no single best ILS for multifamily. The right mix depends on the market, the property's class, whether it is in lease-up or stabilized, its unit count and the cost per lease each site produces at that property. Choose property by property, judge each ILS against its own portfolio rate, and test changes before rolling them out.Read the guide
