Plan review is the backbone of a safe, compliant, and efficient building process. Whether you’re a property owner, architect, or contractor navigating building permit CT requirements, understanding submission standards for drawings, specifications, and codes will save time, reduce costs, and help you avoid rework. This guide covers what reviewers look for, how to structure your submittals, common pitfalls, and how local variables—such as Wethersfield permits, contractor licensing CT requirements, and inspection requirements—fit into the bigger picture of construction approvals.
The goal of plan review is threefold: verify compliance with adopted building codes, evaluate life-safety and structural integrity, and ensure the proposed work matches applicable zoning, environmental, and accessibility provisions. Your submittal should make that evaluation straightforward.
Key concepts to keep in mind:
- Completeness: Reviewers should be able to determine compliance without guessing. Consistency: Drawings, specs, and code narratives must align. Traceability: Code citations should map directly to plan sheets and details. Local alignment: Each jurisdiction may have unique submittal, permit fees, and inspection requirements.
What to include in a complete plan review package
1) Administrative documents
- Permit application process: Submit a fully completed application with project scope, use and occupancy classification, construction type, estimated valuation, and project contacts. For Wethersfield permits and other building permit CT jurisdictions, verify the latest forms and electronic submittal portals. Proof of contractor licensing CT: Provide current licenses for general contractors and any trade contractors as required by state law. Include lead/asbestos certifications when applicable. Engineering review triggers: Identify whether structural, civil, geotechnical, mechanical, electrical, plumbing, or fire protection designs require sealed calculations or reports by Connecticut-licensed professionals. Site control and approvals: Include zoning sign-off, wetlands approvals, or historic commission decisions if required before construction approvals. Fee disclosures: Many jurisdictions require payment of plan review or permit fees at submission or prior to issuance. Clarify the fee schedule and payment timing.
2) Drawing standards
- Title sheet: Project address and parcel ID, code summary (current adopted codes in CT and local amendments), occupancy classification(s), construction type, fire-resistance rating strategy, occupant load calculations, egress summary, special inspections list, and deferred submittals. Scale and legibility: Draw to a consistent architectural or engineering scale; ensure line weights and text are readable in both print and digital formats. Coordination: Architectural, structural, MEP, fire protection, civil, and landscape drawings must align. Call out references between sheets for details and sections. Life safety plans: Show egress paths, exit widths, travel distances, common path, dead-end corridors, stair pressurization (if applicable), number and location of exits, exit signage, emergency lighting, and fire-resistance-rated assemblies with UL/Gypsum Association design numbers. Structural drawings: Foundation plans, framing plans, details, schedules, and connection details. Include design criteria (risk category, wind speed, exposure, seismic design category, frost depth, snow loads, bearing capacity). MEP and fire protection: Equipment schedules, single-line risers for electrical and fire alarm, plumbing isometrics, ventilation/airflow rates, smoke control (if used), and equipment clearances and access. Energy compliance: Envelope details, COMcheck/REScheck reports or energy modeling results, HVAC efficiencies, lighting controls, and air sealing strategies. Accessibility: Accessible routes, door clearances, restroom layouts, reach ranges, signage, and parking with van-accessible spaces and slopes. Site drawings: Limits of disturbance, erosion and sediment control, utilities, grading, drainage, and sight triangles. Stormwater compliance may trigger additional engineering review.
3) Specifications and product data
- Project manual: Organize by CSI divisions with clearly identified performance and product requirements. Align with drawings to avoid conflicts. Product cut sheets: Provide for critical life-safety components (firestopping systems, fire doors, hardware, sprinklers, alarms) and energy-related components (insulation, windows, HVAC). Fire-resistance and assemblies: Reference tested assemblies; include details for continuity at penetrations and joints. Indicate smoke and draft control where needed. Quality and testing: Special inspections, material tests, commissioning plans for energy systems, and procedures for inspection requirements.
4) Calculations and narratives
- Structural calculations: Signed and sealed by a CT-licensed engineer where required, with load paths and lateral system design clearly documented. Mechanical, electrical, plumbing calculations: Duct sizing, load calcs, fault current and AIC ratings, voltage drop, pipe sizing, fixture counts, and water heater recovery. Egress and occupant load: Provide occupant load factors, egress capacity calculations, stair and door width calculations, and elevator egress accommodations where applicable. Code compliance narrative: Cite sections of adopted codes and local amendments; explain alternative materials/methods requests and performance-based designs if used.
5) Local code adoption and amendments
- Building permit CT jurisdictions typically adopt the Connecticut State Building Code (based on I-Codes with amendments). Always verify the current edition and any local addenda. For Wethersfield permits, check the town’s website or building department for specific submittal checklists, digital upload standards, and plan review timelines.
Submittal format and process tips
- Digital submittals: Combine documents into organized PDFs with bookmarks by division or discipline. Flatten markups and ensure layers print correctly. Sheet indexing and revisions: Maintain a master sheet list; cloud and date all revisions. Provide a revision narrative addressing plan review comments. Deferred submittals: Identify early (e.g., fire sprinkler shop drawings, trusses, curtain wall) and propose a schedule that still supports construction approvals. Coordination meetings: Pre-submittal or early plan review meetings can clarify expectations and avoid cycles of comments. Response quality: When comments arrive, respond point-by-point with references to updated sheet numbers and specification sections. Avoid partial or ambiguous responses.
Permit fees, timelines, and approvals
- Fees: Permit fees and separate plan review fees vary. In some building permit CT jurisdictions, fees scale with valuation or square footage, and separate trade permits may apply. Timelines: Plan review time depends on completeness, project size, and whether third-party engineering review is required. Complex projects may use phased permits (foundations, structural frames) with conditions. Conditions of approval: Address all conditions prior to permit issuance. Some conditions may defer to inspections but must be documented.
Inspections, closeout, and certificate of occupancy
- Inspection requirements: The approved plans govern inspections. Keep a current stamped set on site. Expect inspections for footing, foundation, framing, rough and final MEP, insulation, fire systems, and final site. Special inspections: Engage special inspectors early for structural steel, concrete, soils, fireproofing, and smoke control testing if required. Changes during construction: Submit revisions for plan review before building work deviates from approved documents. Closeout: Provide test reports, commissioning documentation, O&M manuals, as-builts, and final affidavits. Once all inspections pass and conditions are met, the jurisdiction issues a certificate of occupancy.
Common pitfalls to avoid
- Missing code summary or incorrect occupancy/construction type classification. Uncoordinated life safety plans versus architectural and structural layouts. Energy compliance documents omitted or mismatched with drawings. Product substitutions that do not match listed assemblies. Lack of clarity on egress widths and door hardware functions. Ignoring local submittal checklists for Wethersfield permits or other towns.
Best practices to streamline approval
- Start with a comprehensive plan review checklist tailored to the jurisdiction. Hold internal coordination reviews across disciplines before submitting. Provide a concise, well-organized code narrative mapping drawings to code sections. Budget for permit fees and third-party reviews upfront. Keep communication open with plan reviewers; professional, timely responses build trust and speed construction approvals.
