A micro SaaS that auto-generates city-specific renovation permit application packages for homeowners
priced at $99 one-time + $19/mo SMS
The key is "paperwork paralysis" — what stops homeowners isn't the ability to do the work, it's not knowing which drawings, affidavits, and inspection dates the municipal permit office actually wants. The moat is localization, one city at a time (2 new jurisdictions a week).

PermitSync isn't a product with revenue already running — it's an executable idea Greg Isenberg threw out in MicroSaaS 101 for you to copy. There's a reason he raised it: in the same session he mentioned a tool called Bank Statement Converter, which does nothing but convert bank statement PDFs to Excel — about as boring a chore as exists — and yet gets to $40K/mo. Greg's logic is that the genuinely stable micro SaaS is usually unsexy: it solves a specific hassle that a certain group of people runs into every so often, and that is both annoying and urgent when they do. Before an American homeowner renovates (adding a deck, redoing a kitchen, installing a water heater), the law almost always requires a permit from the city first. The problem is that every city wants something different: which forms, whether a structural engineer's stamp is required, whether a neighbor-consent affidavit is needed, where the inspection sits in the sequence — to anyone who hasn't done it, it's a tangle. The result is that huge numbers of homeowners get stuck at step one, put off starting work, or pay through the nose for someone to file on their behalf. PermitSync productizes this: answer three questions (which city, what project, how much square footage) and it hands you a filled-out application package plus a next-steps checklist. Greg gives no real revenue numbers — that has to be flagged honestly — but he spells out the pain point, the moat, the pricing, and the upgrade path, which puts this in the most actionable tier of his long list of ideas.
The first buyers of a city-specific permit package come out of one city, never from a national launch. The opening move is to pick a single metro, normalise its published permit checklist, and cover the three projects homeowners actually file for — a deck, a kitchen remodel, a water heater swap.

Data credibility: A replicable idea Greg Isenberg laid out in his MicroSaaS 101 video, with no real revenue figures given; the Bank Statement Converter example from the same session ($40K/mo) shows this class of "boring but necessary" model can reach five figures a month. All revenue figures are founder-reported or estimated by the video creator, unaudited.
The first $99 comes from a homeowner who has already opened the city's own website, failed to understand it, and is a day away from putting the project off. That is the buying moment, and it is a relief purchase rather than a comparison.
Localisation is the flywheel, and it turns on grunt work rather than on virality.
The quiet period in this business is the localisation grind: weeks of turning messy, jargon-heavy municipal checklists into uniform structured fields, with growth that climbs in a straight line rather than spiking. The metric that keeps that honest is paid packages per city, not total traffic.
