Public permits go in. A dollar-sized, trade-timed call list comes out. Here's the whole engine.
A building permit isn't just paperwork — it's a countdown clock. The moment a permit is issued, every trade that will eventually work that site has a predictable window before their phone should ring. Radar Mountain watches the permits so you don't have to, and tells you where each site sits on that countdown for YOUR specific trade.
Live from Nashville's Metro open-data feed, Franklin's own city permit server, and Murfreesboro's — the same public records the county and city keep, refreshed regularly. No scraped listings, no stale leads bought and resold five times.
New construction, townhome and multifamily builds, demolitions (the earliest possible "a lot is about to become a job" signal), and residential rehabs all get sorted automatically.
Every site gets an estimated trade-package value based on unit count and project type, so a 30-unit townhome build and a single kitchen remodel don't look the same on your call list — because they aren't.
Framing crews get called immediately. Cabinet and countertop shops get called months later. Landscapers get called last. Pick your trade and the whole map re-scores instantly to that trade's real buying window.
Where the public data supports it, we cross-reference ownership and permit records to attach a real company name — not just an address — so your call list is a list of people, not pins on a map.
One click groups everything correctly (one big building is one call, not forty), ranks it by dollar value, and gives you a copy-paste list ready for your first call of the day.
This is the part almost nobody else tracks. Below is a sample of how the clock runs after a permit is issued — the same live data, thirteen different countdowns.
| Trade | Typical buying window |
|---|---|
| Framing | Immediately — 0 to 3 months |
| Roofing | 1 to 4 months |
| Plumbing | 1 to 5 months |
| Electrical | 1 to 5 months |
| HVAC | 1 to 5 months |
| Drywall | 3 to 6 months |
| Cabinets | 4 to 8 months |
| Painting | 4 to 8 months |
| Garage Doors | 3 to 7 months |
| Countertops | 5 to 9 months |
| Flooring | 5 to 9 months |
| Appliances | 6 to 10 months |
| Landscaping | 7 to 12 months |
Gold rings mean a site is in your trade's window right now. Dashed rings mean it's coming soon. Faded markers have likely already passed their window — still visible, just deprioritized.
Public building-permit and property records published by Metro Nashville, the City of Franklin, and the City of Murfreesboro — the same records anyone could request, just organized and refreshed for you.
Markets refresh on a regular schedule as part of our data pipeline. We're not reselling a static list — the map reflects current permit activity.
No — they're planning estimates based on project type and unit count, meant to help you prioritize which calls to make first, not a quote or a guarantee.
Not every permit source publishes contractor information. Where it's missing, we still show the address, project type, and timing — and where multiple permits cluster in a pattern that looks like one project, we flag that too.
Yes — every subscription includes all 13 trades. Switch anytime from the dropdown on the map; there's no extra charge per trade.
You'll be billed $99.99/month automatically unless you cancel before the trial ends. No long-term contract — cancel anytime.
