River Valley Construction

Permits are pulled before work begins and then inspected by the county. A contractor who files them is working inside a system with an inspector in it, which is what unpermitted work avoids.

What the permits show

Of the permits we observed, 81% are deck & patio work.

Licensing

Frederick County does not publish license records with its permit data, so none appear here. That is a gap in the county's published data, not a statement about this contractor.

Towns we observed them working in

We hold permit records for Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Frederick County, Howard County, Prince George's County, and Washington DC. Work anywhere else is not missing from this contractor's record, it is outside what we cover.

Permits by year

Our records for this contractor's counties begin August 2021. Years before that are not shown because we hold nothing for them, not because nothing happened.

What this page is, and is not

• Frederick County: 21 permits observed, from records beginning August 2021.

This page shows permits we observed in county records. Our observation is not complete: work done before those dates, in counties we do not cover, or on filings that name no contractor does not appear here. A contractor's real work is almost always greater than what we observed, and absence of a permit on this page does not mean the work was not done or not permitted. We currently hold records for Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Frederick County, Howard County, Prince George's County, and Washington DC; see permit coverage for what that includes.

Common questions

Does a permit record mean this contractor is licensed?

County permit records here do not list a license type for this contractor. That does not mean the contractor is unlicensed; not every county publishes license data with its permits.

Why do some contractors show more permits than others?

Counties began publishing at different times and describe contractors differently, so the number reflects what we observed as much as what the contractor did. It is not a ranking.

What should I still ask for?

Proof of insurance, a written contract, and the license number for the trade being performed. A permit record is a starting point, not a substitute for either.
