The ideaWhat this actually is

A local data business that turns two public record streams, city building permits and new business registrations, into clean weekly territory lead lists for the companies that sell to people mid-project or just starting out. A reroof permit is a shingle distributor's lead; a commercial buildout is an equipment rental yard's lead; a fresh LLC is an insurer's or commercial cleaner's lead. You aggregate scattered, inconsistent government portals, verify and segment the rows by what each buyer sells, and deliver a subscription feed. It sits below the enterprise construction-intelligence platforms that price out every local seller.

The opportunityWhy this idea works

Permit and registration filings are public, refreshed constantly, and legally resellable, but they live across dozens of inconsistent portals, which is exactly the tedious aggregation that makes a durable small data business. Enterprise platforms serve national builders at enterprise prices, leaving the lumberyard and the signage shop with no affordable territory feed. The value of reaching a project owner while the project is still on paper keeps rising as the trades selling to them get more competitive.

The openingWhy this idea is overlooked

There is no glamour here: it is government portals, parsing edge cases, and weekly verification discipline. Data entrepreneurs chase national platforms and lead sellers chase homeowners, so the overlap of people who will maintain scrapers, verify by hand, and enjoy selling to trade sellers is small. The gap is not information, it is willingness to do unglamorous work repeatedly, which is what makes it defensible.

The buildWhat you need to build this

You need	Why it matters
One busy metro's two filing systems	Permits live with the city or county and registrations with the state or clerk; mastering both for one market beats shallow coverage everywhere.
A verification and enrichment habit	Addresses change, records duplicate, and applicants need attaching; the weekly cleanup is what subscribers actually pay for.
Buyer-side segmentation	The raw rows are worthless until sorted by trade; the segmentation is the product, not the filing dump.
Deal-economics interviews	What one closed deal is worth per category sets your price far better than your own effort ever could.
A simple delivery format	A weekly email or spreadsheet feed sells now and proves value before you build any portal software.

Building permit leads for contractors and suppliers: the honest path

So if you have been wondering about building permit leads for contractors and suppliers, the steps below are the real answer, minus the hype.

The roadmap

How to start, step by step

1
Choose one metro and master both filing systems
Building permits live with the city or county; new business registrations live with the state or county clerk. Learn both portals for one busy metro, including their quirks, update cadence, and terms for public records reuse.
2
Segment the feed by what buyers sell
A reroof permit matters to shingle distributors, a commercial buildout to equipment rental and signage, a pool permit to fencing companies, a fresh LLC registration to insurers, banks, and commercial cleaners. The segmentation, not the raw rows, is the product.
3
Verify and enrich every batch
Confirm addresses, dedupe, attach the contractor or applicant of record, and add business contact details where public sources allow. One week of sloppy rows costs the subscription; the verification habit is the moat.
4
Interview sellers to set the price
Ask five prospective buyers in different categories what one closed deal from a mid-project lead is worth. Price territory subscriptions off deal economics, not off your effort.
5
Sell the sample week
The pitch is a real, current week of their territory's filings, segmented for their trade. Deliver by email or spreadsheet; build software only when subscribers ask for integrations.
6
Expand carefully along subscriber demand
Add adjacent metros and filing types (liquor licenses, health permits) as customers request them, and note that the two-card limit for this engine in this bank is deliberate: this card and the liquor license card are the same pipeline pointed at different buyers.

The traps

Common mistakes that kill this business

Mistake	What happens
Selling stale or unverified rows	One batch of wrong addresses or duplicates and the subscription cancels; freshness and accuracy are the whole value.
Building a portal before selling a feed	Months of engineering spent before learning buyers pay for timely rows, not features.
Ignoring segmentation	A raw permit dump forces the buyer to do your job, so they leave; sorting by trade is the reason they pay.
Expanding to ten metros too soon	Every metro is its own maintenance burden; shallow coverage everywhere yields a feed nobody can rely on.

The money

How this idea makes money

Territory feed subscriptions

Monthly per-metro pricing per buyer category, the core recurring revenue.

Category-exclusive tiers

A premium for being the only supplier in a trade receiving a territory's feed.

Adjacent filing feeds

Health permits, liquor filings, and buildout permits sold to the same subscribers from the same pipeline.

The start

Your first 7 days

Day 1Pick one busy metro and locate its building-permit and business-registration portals.

Day 2Pull one real week of filings by hand and study what each record contains.

Day 3Interview three local sellers in different trades about what a mid-project lead is worth.

Day 4Draft your segmentation map: which filing type maps to which buyer.

Day 5Build a verification checklist and clean one sample week into a segmented feed.

Day 6Price territory subscriptions off the deal-economics interviews.

Day 7Send the sample week to five sellers with a simple be-first pitch.

The fit

Who this is for, and who it is not for

Best for: A data-comfortable operator who likes selling practical tools to practical businesses

Not for: Anyone who wants a set-and-forget product or hates recurring maintenance; the feed is only as good as its most recent verified batch.

Your first move

Pick one metro with accessible permit and business-registration data, build a weekly verified feed segmented by project type and filing type, interview local sellers about what a mid-project or new-business lead is worth, and sell territory subscriptions with a sample week as the pitch.

Questions

What people ask about this idea

Is reselling permit data legal?

Permit filings and business registrations are public records, and compiling and reselling public records is a long-established model. Document your sources, honor each portal's terms, and sell business-contact data responsibly.

Which buyers pay the most?

Trades with high value per project: building material distributors, equipment rental, signage, and for new registrations, insurers, banks, and commercial services. Interview each; it varies by market.

What is the moat?

Coverage and reliability. Anyone can scrape once; two years of verified, on-time, well-segmented feeds and subscriber relationships are hard to copy.

How fast can it earn?

Fast for a data business: one clean metro, one buyer category, and a few sample weeks can produce first subscriptions inside 60 to 90 days. Ranges only; results depend on your market and sales effort.
