Columbia, SC Building Contractor List with Phone Numbers

Say you sell commercial doors and hardware out of Columbia, South Carolina, and next month you want to phone every general contractor in town that can bid a commercial building job. In South Carolina that set of firms is defined by one licence classification: Building (BD), issued by the Department of Labor, Licensing and Regulation (LLR). You need names, phone numbers and, ideally, the owner’s name before you start dialling, and you want the bigger firms first.

The manual way, and what it costs

LLR’s contractor lookup is free and it is the right tool for checking one firm. For a list, it is slow. Every search sits behind a reCAPTCHA, and the result list gives only the name, city and status. The phone, street address, classifications and officers are on each licence’s own detail page. Columbia has 228 Active BD licences, so the list means 228 detail pages, copied by hand into a sheet. And the city search also returns lapsed and closed licences (497 for Columbia BD across every status), which you then have to weed out. If you need ten firms, do it by hand. For two hundred, it is a long day.

The faster way

South Carolina Contractor Directory & Leads Scraper (LLR) does the same search once and hands back every row at once.

{
  "city": "Columbia",
  "classification": "BD",
  "maxResults": 500
}

city: "Columbia" is an exact match on the licence’s address city, so it is Columbia proper. Add Lexington, Irmo, West Columbia and Cayce in cities and the same search was 408 contractors. classification: "BD" is an exact code match on Building. Active licences with a South Carolina address are the default, and maxResults: 500 is just headroom. On the 2026-10-24 roster this returned 228 contractors.

Field	Example value	Meaning
business_name	RUMSEY CONSTRUCTION & RENOVATION LLC — DBA: RUMSEY CONSTRUCTION & RESTORATION	Licensed business name, with any DBA after it
phone	(803) 764-0222	Phone number on the licence’s LLR detail page
address	2630 SHOP RD	Street address on file with LLR

address_state	SC	State of that address (SC unless you turn off ‘South Carolina addresses only’)
zip_code	29209-4600	ZIP or ZIP+4

For a calling list, phone closes the loop, and 226 of the 228 rows had one. officers gives you a name to ask for: on 151 rows one of the officers is listed as President / Owner. classifications sorts the list by size: the digit after “BD” is the licence-limit group, and 71 of the 228 are BD5, the top group, while 52 rows are Construction Manager licences that carry the classification with no group at all.

What you’d do with it

Export the dataset to CSV, sort on classifications so the BD5 and BD4 firms come first, and load it into the dialler or CRM you already use. Add a column for “estimator” and one for “next follow-up”. The run cost $0.456 (228 rows at $0.002), so re-running it each month and diffing license_number against your sheet is a cheap way to catch new BD licences in Columbia.

Worth knowing

There is no email on any row: LLR does not publish one, so this is a phone list. The roster is a monthly snapshot, up to about a month old, and the run log states its date. 107 of the 228 licences expire on 10/31/2026, so the next monthly roster will show which of them renewed. One firm can appear twice, once with a General Contractor licence and once with a Construction Manager licence: the 228 rows are 172 distinct business names. Residential builders are licensed by a different LLR board and are not here.
