How this service works
Use to check whether a commercial building budget in the Rio Grande Valley, Texas is in line: median and 25th-75th percentile of filed estimated cost per square foot over the last 24 months, by county (Hidalgo, Cameron, Starr, Willacy) and type of work (new construction, renovation, addition), with n. For estimating, appraisal and lending checks. Filed estimates, not bids. Example: "What does new commercial construction cost per square foot in Hidalgo County right now?"
Output
A JSON object containing the query date, the queried county, a groups array with per-work-type breakdowns (n projects, median USD/sqft, p25/p75 USD/sqft, median square footage, date range of filings), plus metadata fields including data source, rolling window in months, cadence (weekly), dataset name, publisher, and a disclaimer about data staleness thresholds.
Example use cases
Homebuilder feasibility check
“I'm planning a new construction project in Cameron County — can you pull the current median cost per square foot and the typical range so I can rough out a budget?”
Renovation cost benchmarking
“What's the going rate per square foot for renovations and alterations in Hidalgo County based on recent state filings? I need the median and interquartile range.”
Cross-county cost comparison
“Can you get me the cost-per-sqft stats for all types of work in Starr County so I can compare it against what we're seeing in Hidalgo County?”

Choose this endpoint when you need hyperlocal construction cost benchmarks specifically for the Texas Rio Grande Valley border counties (Hidalgo, Cameron, Starr, Willacy), sourced directly from public state construction filings and refreshed weekly. It is ideal for feasibility analysis, budget estimation, and market benchmarking in these specific counties. It is not suitable for statewide Texas data, national benchmarks, or counties outside this region.
