An HOA or community notice board app needs four things: announcements with push notifications, a document library (bylaws, minutes, budgets), dues reminders that link to your existing payment method, and an opt-in resident directory. Describe those to App Builder Agent in one prompt and the AI agent builds an Android app with a hosted backend so every resident sees the same board; the board updates it by typing. A first version fits in the free plan; the Member plan is $1.49 per 30 days at the time of writing for unlimited builds.
Whether you call it a homeowners association in the US, a residents' association or management company in the UK, or an owners' association in the EU, the job is the same: keep a few dozen to a few hundred households informed, store the documents somewhere findable, and get dues paid on time without a stack of letters. Email lists get ignored, group chats drift, and paid community platforms charge per unit per month for features a small association never uses. A small app of your own, built by describing it, sits between the two.
What the app needs
- Announcements with categories (notice, maintenance, event, urgent), a pinned item, and a push notification for urgent ones. Residents can tap a Seen button so the board knows a notice landed.
- Documents in folders: governing documents (CC&Rs, bylaws, rules; in the UK the lease and the estate regulations), meeting minutes, budgets and financial statements, the insurance certificate. PDF upload by the board, search by title.
- Dues and fees: each household sees its schedule (monthly or quarterly dues, special assessments, the service charge in the UK), a reminder before the due date, and a Pay button that opens the association's existing payment page or shows bank transfer details. No card processing in the app.
- Resident directory, opt-in: name, unit, phone or email, and only the fields the resident ticks. Visible to signed-in residents only.
- Maintenance requests: a form with photo and location, a status (received, scheduled, done), and a list the board or manager works from.
- Events and meetings: the annual general meeting, board meetings, community events, with an RSVP and the agenda attached.
- Board admin: a role that can post, upload, edit the dues schedule and approve new residents; residents sign up with an invite code per unit.
Everything here is shared data, so the agent will add a hosted backend (database, auth, file storage) on the platform's infrastructure. If you only need a one-way board, a website published at a link is an option, but the directory and dues reminders want accounts.
The prompt to paste
Open App Builder Agent, sign in with Google, choose a mobile app and paste one message. Change the name, the unit count and the wording to match your association.
For a UK residents' association, swap the wording: "service charge and ground rent" for dues, "lease and estate regulations" for governing documents, GBP for USD, and "managing agent" as a third role if a management company posts on your behalf. For an EU owners' association, "assembly of owners" and "administrator" are the terms residents expect, with the amount in EUR.
What you get in the first minutes
The agent writes the screens, creates the backend tables (residents, homes, announcements, documents, dues, requests, events) and shows the app in a phone preview in the browser. Post an announcement as the board, then sign in as a resident in the preview and check it shows, mark it Seen, upload a test PDF and search for it, file a maintenance request with a photo. Then iterate by describing changes:
The generated code is visible in the editor if a technically minded board member wants to see what stores what.
Getting it onto phones
For a first rollout, the Download APK button gives an installable Android build you share by link or in the next newsletter; residents allow installs from the browser once and tap the file. When the board is happy, ask for a signed build (signed APK and AAB with a package id such as com.maplegrovehoa.app) and publish it on Google Play so residents find it by name; the signed APK and AAB guide and the Google Play publishing guide cover the $25 registration, the testing requirement for personal accounts and the privacy policy Google asks for. Builds are Android only; residents with iPhones use the same project published as a website at a link on appbuilderagent.com, which the agent can build from the same description.
What it costs
At the time of writing the free plan includes 500K AI tokens a month (with a free APK download), with every feature and no card. That covers the prompt above and a couple of rounds of changes. The Member plan is $1.49 per 30 days for 5M tokens, unlimited APK builds and source export; Pro ($5.72), Business ($31.12) and Max ($11.01) add larger allowances. The hosted backend runs on the platform's servers. Compared with per-unit community platforms, the running cost is the plan, and the association keeps the ability to export its data and delete the project. Prices can change; check the AI app builder page for current plans.
Notes for the US, UK and EU
The app does not replace legal notice. In many US states, HOA statutes specify how meeting notices and assessments must be delivered (by mail, or by email with the owner's consent), so treat the app as an extra channel until your attorney confirms that electronic notice through it counts. Keep the official minutes and financials in the app, but keep the originals in the association's records. In the UK, residents' associations, right-to-manage companies and managing agents have their own consultation rules for service charges; the app's job is to make the documents easy to find, not to change the process. Across the EU and UK, the resident directory is personal data: keep it opt-in, show residents exactly what others can see, and give the board a way to delete a household when it moves out. Under GDPR and UK GDPR you need a privacy notice and a lawful basis; in California, CCPA gives residents rights to know and delete. This is general information, not legal advice; the privacy policy guide lists what to include.
If your community is closer to a club or a neighbourhood group than an association, the social app guide and the chat and messaging guide cover feeds and group chats. Browse the community and social apps for board layouts, then paste the prompt with your association's name.
Frequently asked
Can residents pay dues inside the app?
Keep payments outside the app. It sends reminders and a Pay button that opens your existing payment page or shows bank transfer details, which avoids card-processing fees and store rules for a volunteer board.
How do residents get the app on their phones?
Share the Android APK by link for a first rollout, or publish a signed build on Google Play so residents find it by name. Residents with iPhones use the same project published as a website at a link.
Is the resident directory private?
Yes, if you ask for it that way. Each resident opts in and chooses which fields to show, only signed-in residents can see it, and the board can remove an entry when a household moves out.
Does the board need a developer to update the app later?
No. The board member who holds the account describes changes in the chat (a new document folder, a new category, a different reminder) and the agent edits the code. The account can be handed over when the board changes.
What does it cost to run?
At the time of writing the free plan covers building a first version (500K AI tokens a month); a free APK download is included. The Member plan is $1.49 per 30 days for unlimited builds and source export. The hosted backend runs on the platform, and the association can export its data and delete the project.
