Jurisdiction guides: what to learn about an AHJ before you submit.

Two projects with identical drawings can move very differently across a county line. This guide covers how LPG researches an Authority Having Jurisdiction — the agencies, the adopted codes, the portal, the fees and the local practices that don't appear in any code book.

Key takeaways
  • The first question is never 'what does the code say' — it's 'who has authority here, and for what?'
  • Adopted code editions and local amendments vary widely; a state baseline is a starting point, not an answer.
  • Portal mechanics, naming conventions and intake screening rules cause more rejections than code issues do.
  • Fee structures and required pre-application meetings belong in the schedule before design is finalized.

Step one: identify the Authority Having Jurisdiction

An address inside city limits, an address in the unincorporated county, and an address in a special district can each answer to a different building department, fire authority and utility provider. Before anything else, LPG confirms which agency issues the building permit, which fire authority reviews life safety, whether health department review applies, and whether the site sits in an overlay, historic district, airport influence zone, community development district or special taxing district that adds a review layer.

  • Building permit authority — city, county, or a consolidated code-enforcement agency
  • Fire review authority — local fire marshal, county fire authority, or state fire marshal
  • Planning and zoning authority, including overlays and design review boards
  • Health department jurisdiction for food service, pools and onsite septic
  • Public works and transportation for right-of-way, access and driveway permits
  • Utility providers — municipal, cooperative, private or investor-owned

Step two: adopted codes and local amendments

Adopted editions matter. Some states adopt a statewide code with mandatory local enforcement, others leave adoption to the locality, and many localities layer amendments on top of the state code. LPG documents the adopted building, residential, fire, mechanical, plumbing, electrical, energy and accessibility standards for the jurisdiction, then looks specifically for local amendments and technical bulletins — the amendments are where projects get surprised.

  • Building and residential code editions currently in effect
  • Fire code edition and referenced NFPA standards
  • Energy code or state-specific energy compliance path
  • Accessibility standard, including any stricter state requirement
  • Local amendments, ordinances and administrative bulletins
  • Effective dates and any grandfathering rules for in-progress projects

Step three: submittal mechanics

This is the layer most teams underestimate. How a jurisdiction wants the package delivered often decides whether it clears intake on the first try. Sheet size and orientation, separate versus combined PDF files, digital signature and seal formats, file naming, maximum upload size, and whether the trades submit under the building permit or as separate applications are all jurisdiction-specific.

  • Permitting portal and whether an account or contractor registration is required first
  • Digital signature and professional seal requirements
  • File format, file separation and file naming conventions
  • Whether trade permits are combined with or separate from the building permit
  • Intake screening or prescreen process and what it checks
  • Whether third-party or private provider review is permitted

Step four: fees, timing and required meetings

Published fee schedules, impact fees, mobility or transportation fees, utility connection charges and plan review deposits all belong in the project budget early. Where the jurisdiction publishes review turnaround targets, LPG records them as published targets — not commitments. Required pre-application or pre-submittal meetings can add weeks if they are discovered after the design is complete.

  • Published fee schedule and how valuation is calculated
  • Impact, mobility and utility connection fees where applicable
  • Published review turnaround targets and resubmittal handling
  • Required pre-application, pre-submittal or DRC meetings
  • Permit expiration, extension and revision rules

Step five: local practice

Every jurisdiction has unwritten patterns — which reviewer disciplines comment most, which documents intake always asks for even when the checklist doesn't list them, whether comments are issued per-discipline or consolidated, and how revisions and deferred submittals are handled. This knowledge is built over repeated projects and direct agency contact, and it is often the difference between one review cycle and three.

How LPG uses this on your project

Jurisdictional research is the foundation of our Site Investigation Reports and of every permit we manage. We assemble the agency map, the permit matrix, the submittal requirements and the fee picture, then keep it current as the project moves. When something is not published or cannot be confirmed, we say so and mark it for direct agency verification rather than presenting an assumption as a requirement.

Frequently asked questions

Can you tell me the requirements for any jurisdiction in the country?
We research any U.S. jurisdiction, and we maintain verified requirement libraries for jurisdictions we work in regularly. For a new jurisdiction, requirements come from that agency's published materials and direct contact — not from assumption.
Isn't the code the same everywhere?
The model codes are broadly consistent, but adoption editions, state amendments, local amendments, zoning and submittal procedure are not. Local requirements are usually what determines whether a package clears intake.
Can you tell me how long review will take?
We report published review targets and what we've observed on comparable projects. Official review and approval timelines are controlled by the jurisdiction and utility providers, and we don't guarantee them.
Do you handle pre-application meetings?
Yes. Where a jurisdiction requires or offers a pre-application or pre-submittal meeting, we identify it, schedule it, prepare the materials and coordinate the design team's attendance.

Jurisdictional requirements change. Code adoptions, fee schedules, portal procedures and local amendments are updated by the agencies that publish them, and this guide is educational rather than a substitute for direct verification with the Authority Having Jurisdiction on a specific project.

Need the jurisdiction mapped before you design?

LPG researches the agencies, codes, submittal requirements and fees for your site so the design and schedule are built on the actual path to approval.
