Step 1 of 5: Project and client information
Plain-language terminology
Permit terms, without the shorthand.
Use these definitions as orientation, not as a substitute for the applicable code, agency direction, or professional review.
Alteration and repair
Changing, replacing, or fixing an existing building or its systems. Example: reworking a storefront or repairing a damaged structural member. It matters because the permit path depends on what is changed and how much of the existing building is affected.
Renovation
Updating an existing space or building. Example: modernizing a lobby and restrooms. It matters because even cosmetic-looking work can trigger building, trade, accessibility, or fire review.
Tenant improvement
Work that prepares an existing space for a particular tenant. Example: dividing an open office into rooms for a new company. It matters because the tenant scope, occupancy, and base-building conditions often determine the permit set.
Tenant fit-out
The construction and installation that turns a shell or existing suite into an operating space. Example: adding a restaurant kitchen, counters, and finishes. It matters because fit-outs commonly involve building, MEP, fire, accessibility, and sometimes health review.
Addition
New floor area attached to an existing building. Example: adding a rear classroom wing. It matters because the addition can affect zoning, lot coverage, structure, utilities, stormwater, and the existing building.
New construction
Building something where a building does not currently exist. Example: constructing a new warehouse on a vacant parcel. It matters because it usually requires coordinated building, site, zoning, utility, and life-safety approvals.
Change of use
Changing what a space is used for. Example: converting retail space into a restaurant. It matters because the new use can change zoning, occupant load, egress, fire protection, accessibility, and system requirements.
Change of occupancy
A code classification change based on how people occupy the space. Example: converting an office to an assembly venue. It matters because it can trigger a deeper code, fire, egress, and accessibility review even when the walls move very little.
Certificate of Occupancy
A document confirming how a building or space may be occupied after required approvals. Example: obtaining a new certificate after a restaurant conversion. It matters because operations may not lawfully begin until the required occupancy documentation is in place.
Building permit
Approval for construction work that changes a building or its safety conditions. Example: a permit for a commercial interior alteration. It matters because approved plans establish the scope that may be built and inspected.
Trade permit
A permit for a specific building system such as mechanical, electrical, or plumbing work. Example: a new electrical service and lighting permit. It matters because trade work may need separate applications, plans, inspections, and licensed contractors.
Structural modifications
Work that changes how a building carries loads or resists forces. Example: removing a bearing wall and adding a beam. It matters because structural calculations, special inspections, and sequencing may be required.
Mechanical / electrical / plumbing (MEP)
The building systems that heat, cool, power, light, supply water, and remove waste. Example: adding rooftop equipment and new branch circuits for a tenant. It matters because each system can have separate technical and inspection requirements.
Fire suppression
Systems that control or extinguish fire, such as sprinklers or clean-agent systems. Example: extending a sprinkler main for a new room layout. It matters because fire protection design and inspection are closely tied to life safety and occupancy approval.
Sitework
Work outside the building that prepares or changes the site. Example: grading, paving, utility connections, or a new retaining wall. It matters because sitework can trigger civil, zoning, stormwater, utility, and land-disturbance review.
Land disturbance
Earthwork or activity that exposes, moves, or changes soil. Example: excavating for foundations. It matters because sediment, erosion, stormwater, and environmental controls may be required before work starts.
Public-space permit
Approval to occupy or affect public right-of-way or public property. Example: placing a dumpster, crane, scaffold, or construction fence in a sidewalk area. It matters because the building permit alone does not authorize use of public space.
Sediment and erosion control
Measures that keep disturbed soil from leaving a site. Example: stabilized construction entrances and inlet protection. It matters because some jurisdictions require an approved plan or inspection before land disturbance.
Zoning
Rules about what may be built and how property may be used. Example: checking whether a restaurant is allowed in a district and whether parking or setbacks apply. It matters because a building permit cannot solve an incompatible use or dimensional issue.
Historic preservation
Review for work affecting a designated historic property or district. Example: changing windows on a historic storefront. It matters because exterior materials, demolition, signage, and visible alterations may need separate approval.
Gross floor area
The total floor area measured under the applicable code or zoning definition. Example: adding a second floor increases the project’s gross floor area. It matters because floor-area limits, fees, occupancy, and thresholds may use different area definitions.
Construction area
The portion of the property or building where work is proposed. Example: a 4,000-square-foot tenant suite within a larger building. It matters because permit scope, review effort, and documentation often depend on the actual construction area.
Lot area
The area of the parcel of land. Example: calculating the lot area before checking coverage or setbacks. It matters because zoning controls often compare building area, open space, and impervious area to the lot.
Building footprint
The area covered by a building where it meets the ground. Example: an addition expands the footprint toward a side yard. It matters because setbacks, lot coverage, stormwater, and site approvals can depend on it.
Construction type
A code classification describing a building’s materials and fire-resistance characteristics. Example: determining whether a project is Type II-B or Type V-A. It matters because construction type affects allowable height, area, fire ratings, and code strategy.
Authority Having Jurisdiction (AHJ)
The public agency or official responsible for reviewing and enforcing a requirement. Example: a county building department reviewing a permit application. It matters because the AHJ, not this website, makes the official determination.
Plan review
An agency’s examination of drawings and documents for code and regulatory compliance. Example: reviewers comment on egress, accessibility, and structural notes. It matters because comments must be answered before approvals can advance.
Third-party inspection
Inspection by a qualified party other than the building owner or general contractor. Example: a special inspector observes reinforcing steel or concrete placement. It matters because the inspection scope and reporting can be a condition of approval or closeout.
Permit expediting
Coordinating permit information, submissions, reviews, responses, and approvals. Example: tracking agency comments and organizing the next response package. It matters because disciplined coordination can reduce avoidable delays without guaranteeing agency action.
