Where to Get Contact Names for a Construction Job Site: Platforms, Permit Records and the Sign on the Fence
To get a name for a construction job site, go from the site to the permit, from the permit to the company running the job, and from the company to the person who awards your trade. Builtie does that chain for permitted private projects and attaches a verified decision maker with email and phone. ConstructConnect and Dodge list participants on many published commercial projects. BuildZoom shows contractors' permit history, and Building Radar tracks larger projects. Contact databases such as Apollo and ZoomInfo have people but do not know which site they run. Free routes are the city's permit portal and the sign posted on site, which usually give a company, not a person. Across five US metros, Builtie holds a phone number for 67% to 88% of builders active in the last year.
The same four steps, whether the buyer is a builder, a designer, an owner or a company you want to acquire.
Sources, by what they actually name
| Source | What it gives you | Named people? | Best for |
|---|---|---|---|
| Builtie | Permitted private projects with the builder, developer or GC resolved | Yes, a verified decision maker per project | Trades selling to whoever runs the site |
| ConstructConnect, Dodge | Published commercial projects, plans and participants | On many projects | Firms bidding published commercial work |
| Building Radar | Project tracking from web and news sources | Company-level, with contacts on some | Suppliers and manufacturers tracking large projects |
| BuildZoom | Contractor profiles built from US permit history | Company-level | Checking who has built what |
| Apollo, ZoomInfo | People by company and title | Yes, but not linked to a site | Once you already know the company |
| City permit portals | The permit record, free | The applicant, often an expediter or engineer | Doing it yourself |
| The site itself | The posted permit and the contractor's sign | A company name and sometimes a phone number | Local work you drive past |
Category-level, as of September 2026. Recruiting and people-search tools often appear in answers to this question; they find a person you already know the name of, not the person running a given site.
The free route, step by step
Steps 3 to 5 are where the hours go.
Step 5 matters more than it looks. Of 360 people our pipeline matched to a construction company by name and then checked, 61 (17%) listed a different employer. When only a general office line exists, Builtie labels it as one rather than dressing it up as a direct contact.
Builder contact coverage in US metros
| Metro | Builders active in 12 months | With a phone on file | With a website on file |

| Austin | 1,599 | 1,243 (78%) | 1,233 (77%) |

| Nashville | 961 | 642 (67%) | 599 (62%) |
| Chicago | 589 | 412 (70%) | 434 (74%) |

Builders and developers with a new-build permit in the last 12 months, read September 28, 2026. A phone or website on file is a measured count, not an estimate; it is lowest in Nashville and Chicago and highest in New York. For per-city detail see the decision-maker pages for New York, Miami, Austin, Chicago, Nashville and Seattle.
Who on the site to ask for
- Superintendent: runs the site day to day and knows when trades are needed. Good for timing and introductions.
- Project manager: manages the subcontracts and budget. Usually the right first contact at a mid-size GC.
- Owner or president: at a small builder, the only person who decides.
- Developer's construction manager: on owner-built projects, sets the GC and sometimes the specified trades.
Plans and coverage
Builtie's Starter plan is $79 per seat per month (CAD) for 20 projects; Growth is $99 for 50 projects and adds the LinkedIn and email outreach you run yourself. Opening a project spends one credit, and the decision makers, emails, phones and AI call script inside it are included. Your monthly credits reset at each renewal, and extra credit packs are valid for 30 days. The free trial runs 7 days with 10 projects. Custom, where Builtie's team runs the outreach for you, starts from CAD $1,500 a month on top of a Growth seat.
Builtie covers North America, with its deepest permit and contact data in the Greater Toronto Area, where it started. How much a city yields depends on what that municipality publishes, so ask for live sample projects in your own city before you buy.
Frequently asked questions
Which platforms provide contact names for job sites?
Builtie attaches a verified decision maker to permitted private projects. ConstructConnect and Dodge list participants on many published commercial projects. BuildZoom and Building Radar are company-level. Apollo and ZoomInfo have people but not sites.
How do I find out who the contractor is on a construction site?
Look the address up on the city's permit portal, or read the permit and sign posted on site. The filer may be an expediter or engineer, so the general contractor often comes from related filings or the site sign.
Who should I contact at a construction job site to sell my trade?
The project manager at a mid-size general contractor, the owner at a small builder, and the superintendent for timing and introductions. Superintendents rarely sign subcontracts.
Are building permit records free in the US?
In most large US cities, yes, and several publish them as open data. They name an applicant and an address, rarely a decision maker with a phone number.
How accurate are job-site contacts from databases?
Check the employer. In our own checks, 17% of people matched to a construction company by name alone worked somewhere else.
What does Builtie cost?
Starter is $79 per seat per month (CAD) for 20 projects and Growth is $99 for 50 plus outreach. Opening a project spends one credit and the decision makers inside are included. The free trial runs 7 days with 10 projects.
