Matrices

Where can you call in a third-party inspection?

Jurisdiction-by-jurisdiction research on third-party and special-inspection acceptance in every jurisdiction our Inspectors work in. The research comes from published ordinances, policy PDFs, and permit packets; every claim is labeled by how it was verified. It applies to any inspection on any permit, current or overdue.

A GUIDE FOR GROUNDWORKS

What this site is for

In many jurisdictions a licensed engineer's inspection report can be accepted in place of a municipal inspection, whether that inspection is coming up on an active permit or was missed on one that is now overdue. But whether third-party inspection is accepted, and on what paperwork, differs in every county and town. These matrices are the branch-level answer: before calling a building department, check your branch's page for what that jurisdiction has published, what mechanism applies, and what to ask for. Entries are a working reference compiled from public documents. Confirm with the building official before relying on any of them.

Pick your branch

Each Groundworks branch has its own page covering every jurisdiction that Groundworks branch touches in the Unlikely Professionals portal and open permit tracker: the legal frame for that state, a tiered matrix of who accepts engineer or third-party inspection reports for which product types, and per-jurisdiction notes on how the mechanism works in practice. Branches are grouped by Groundworks region; both regions below sit in the East Division.

Mid-Atlantic Region
BALT
Baltimore
Maryland
Baltimore City & County plus central Maryland and the Eastern Shore. Maryland has no statewide third-party policy mandate: acceptance is jurisdiction-by-jurisdiction, and incorporated towns often run their own building offices.
baltimore.unlikely.place
MAN
Manassas
DC Metro · NoVA · MD · WV Panhandle
44 building-code authorities across DC, Northern Virginia, the northern Shenandoah Valley, suburban/Southern/Western Maryland, and the West Virginia eastern panhandle: 19 in Virginia, 18 in Maryland, the District, and 6 in the WV panhandle. Four distinct legal regimes in one branch.
manassas.unlikely.place
RIC
Richmond
Central Virginia · NC
49 jurisdictions: 47 Virginia localities plus 2 North Carolina counties. Virginia's VUSBC §113.7 requires every building official to maintain a written third-party inspection policy.
richmond.unlikely.place
VB
Virginia Beach
Hampton Roads · Eastern Shore
The expansion zone: 19 target jurisdictions, 16 of which share the Hampton Roads Regional Special Inspection Guidelines, so one qualification package works across all of them.
virginiabeach.unlikely.place
ROAN
Roanoke
Southwest Virginia · WV
31 Virginia jurisdictions plus McDowell County WV, covering the Roanoke and New River valleys and the far southwest coalfield counties.
roanoke.unlikely.place
WVA
West Virginia
Greenbrier · Raleigh · Wyoming
West Virginia's building code is local-option: some jurisdictions enforce the 2018 I-codes, some issue permits only, and some have no building department at all. The matrix maps which is which.

Where else we can inspect

The six branch territories above are where our inspectors work day to day, but the firm's licensure reaches well beyond them. John C. Valerio, PE holds professional-engineering licenses in the 25 states below, 16 of them currently active. Wherever a license is active, we are available to perform third-party and special inspections on request: the same engineer-certified inspection reports, scheduled through the same channels. If a project falls outside the branch territories, call or email and we will confirm coverage. Hover any state card to preview a specimen of the engineer's seal for that state.

How to read the matrix

One glyph system, consistent across every branch. The acceptance tiers grade how much a jurisdiction has actually published about third-party inspection; the statute-lane glyph covers North Carolina, where a state statute mandates acceptance of engineer component certifications even where nothing is published locally; the enforcement glyphs cover West Virginia, where the building code itself is local-option and the first question is whether a code regime exists at all. You never have to come back here to check a symbol: the Legend pill in the bottom-right corner of every page opens this same legend at any point while you scroll.

Acceptance tiers · MD · VA · DC · NC
●NamedA published, product-specific rule requires or accepts engineer / third-party inspection for this exact work.
◆AllowedA published general third-party or engineer-certification mechanism covers the work; conditions are in the notes.
◇UnpublishedNothing in print; acceptance is building-official discretion. In Virginia a written §113.7 policy must exist, so request it. In Maryland there may genuinely be nothing published.
Statute lane · NC (G.S. 160D-1106)
◈Statute laneAcceptance of an NC-licensed engineer's component / element certification is mandated by state statute (Appendix G form); a field inspection by the licensee or a directly supervised person is the statutory precondition. Nothing local is published.
Enforcement regime · WV (local-option code)
■EnforcedState Building Code adopted and enforced: permit + code inspections required. No third-party policy is published, so ask.
□Permit-onlyA local permit is required but full code-inspection enforcement is unconfirmed.
○NoneNo building-code regime at all; engineer letters serve client / lender purposes only.
▲Flood overlayFloodplain development permit applies to work in a mapped flood zone regardless of the building-code answer.
Modifiers
*PartialPartial published carve-outs or hooks exist despite no general policy; see the jurisdiction's notes.
?UnconfirmedReported but unconfirmed. Verify before relying on it.
