2026 Commercial HVAC, Plumbing & Electrical Permit Intelligence Report

DibDirt's 2026 Commercial HVAC, Plumbing & Electrical Permit Intelligence Report is a practical map of the public-record landscape contractors can use to find commercial project activity earlier.

This report is based on DibDirt's internal source registry, which currently catalogs 52 official public-source entries across all 50 states plus the District of Columbia. The registry is not a claim that every source has equal depth or that every record represents open work. It is a source-quality map: what is available, what each record can prove, and where the limitations are.

2026 source-registry snapshot

• 52 official public-source entries cataloged
• 31 READY sources: verified for active production use
• 4 PARTIAL sources: useful, but with known classification or access limitations
• 17 RESEARCHED sources: identified and documented, but not represented as production-ready
• 36 statewide sources, with the remainder focused on major municipal or regional systems

Important: source count is not the same as project volume. A statewide procurement portal in a small market may produce fewer relevant opportunities than a large-city permit feed. DibDirt does not represent every state as having equal construction activity or equal public-data depth.

Where commercial project signals appear

Commercial construction activity does not live in one national database. Depending on the jurisdiction and project type, useful signals may appear in:

• municipal building and mechanical permit systems
• state plan-review databases
• state project-registration systems
• public-facilities construction programs
• state procurement portals
• public works and construction-bid systems

Those sources represent different points in the project lifecycle. A registration may surface planning activity early. A permit may confirm regulated work. A solicitation may define a formal procurement window. Contractors get better intelligence when those records are treated as different signals rather than flattened into the word “lead.”

What a public record can actually tell you

Across DibDirt's 52-source registry, 50 sources contain a way to identify commercial activity, while two major-city permit sources require more guarded classification because they do not expose a clean commercial/residential field. All 52 sources are cataloged for their ability to surface HVAC or mechanical relevance when that scope is explicitly present.

Other useful fields vary substantially by jurisdiction. The registry records whether a source can expose owners, design firms, contractors, project values, dates, and scope text. This is why one market can support a nearly complete pursuit record while another may only provide a verified project signal and official source link.

Examples of strong source patterns

Texas: statewide project registration

Texas TDLR Architectural Barriers project registrations are statewide and can expose project registration dates, scheduled construction dates, owner/design information, project value, and detailed scope. That makes the source valuable for early commercial-project research, but the record still does not guarantee that a trade package is open.

Philadelphia: explicit commercial and mechanical fields

Philadelphia's public permit data can identify records tagged Commercial and Mechanical and can expose approved scope, contractor information, owner information, address, and permit dates. This is the kind of structured public record that makes trade qualification more direct.

Los Angeles: commercial permit classification

Los Angeles public building-permit data provides commercial permit classification, project valuation, address, dates, and scope text that can be searched for explicit HVAC relevance. It is strong evidence of project activity, not evidence that a subcontract remains available.

New York City and Chicago: useful but classification-sensitive

Some large municipal datasets provide excellent permit and scope detail but do not expose a single authoritative commercial/residential field. DibDirt marks those sources PARTIAL and applies guarded exclusions rather than claiming perfect commercial classification. That limitation is part of the intelligence, not something to hide.

Permit intelligence vs. bid-board intelligence

A bid board answers a different question from a permit or plan-review record. Formal bid systems are strongest when procurement has reached a defined solicitation stage. Permit, registration, and plan-review records can reveal activity before or outside that stage. Neither source type is inherently “better.” The value depends on whether a contractor is trying to prospect early, verify project activity, or respond to an active solicitation.

How HVAC, plumbing and electrical teams should use these signals

The useful workflow is evidence-first:

1. Confirm trade relevance. Use explicit scope or permit type, not assumptions.
2. Read the timing. Application, registration, plan-review, issue, and bid dates represent different stages.
3. Separate total project value from trade value. A $5 million project is not a $5 million HVAC, plumbing, or electrical package.
4. Identify the best contact path. Owner, design firm, applicant, GC, agency, or official solicitation contact, depending on what the record actually provides.
5. Verify procurement status. Public project activity does not prove that work remains unawarded.

Why coverage depth varies by state

Public construction data is fragmented by design. Some states operate statewide plan-review, procurement, or project-registration systems. Others delegate most permitting to municipalities and counties. Some official portals expose APIs; others provide searchable websites, downloadable files, or bid listings. As a result, “nationwide coverage” should never be interpreted as identical record volume or identical field depth in every jurisdiction.

DibDirt methodology

DibDirt separates verified source facts from inference and unknown procurement status. A source can prove that a project, permit, registration, plan review, or solicitation exists. It may also prove location, dates, stated scope, parties, or total project value. Unless the official record says otherwise, it cannot prove that a specific trade contract is still open, unawarded, or worth a particular amount.
