Common Plan Review Rejections
Rejection Reason How to Fix Frequency Missing structural calculations Hire PE to stamp calcs for headers, beams, connections, foundation Very Common Setback violations Redesign or apply for variance (4-12 week delay) Common Energy code non-compliance Update insulation, windows, HVAC specs to current code cycle Common Incomplete drawings Add missing sections, details, dimensions, notes Very Common Fire separation deficient Upgrade wall/floor assemblies to required fire rating Common ADA non-compliance Revise accessible routes, grab bars, clearances, slope Common (commercial) Stormwater not addressed Add detention/retention, pervious surfaces, drainage plan Moderate Zoning use not permitted Apply for conditional use permit or rezone (major delay) Occasional Lot coverage exceeded Reduce footprint or get variance Moderate Height limit exceeded Redesign or apply for variance Occasional
Inspection Sequence (Typical New Construction)
Foundation/Footing — Before pouring concrete. Rebar, forms, depth, soil bearing.
Underground Plumbing — Before backfill. Slope, materials, cleanouts.
Underground Electrical — Before backfill. Conduit, grounding.
Slab — Before pour (if slab-on-grade). Vapor barrier, insulation, embedded items.
Framing — After rough framing complete. Structure, connections, sheathing, holdowns.
Rough Electrical — Wiring, boxes, panel, circuits before drywall.
Rough Plumbing — Supply, waste, vent before drywall. Pressure test.
Rough Mechanical — Ductwork, equipment, venting before drywall.
Insulation/Energy — After rough inspections pass. R-values, air sealing, vapor barriers.
Drywall Nailing — Before taping (some jurisdictions skip this).
Final Electrical — Fixtures, devices, panel schedule, GFCI/AFCI, smoke/CO detectors.
Final Plumbing — Fixtures, water heater, gas connections, flow test.
Final Mechanical — HVAC startup, balancing, thermostat, combustion air.
Final Building — Everything complete. Egress, railings, stairs, smoke detectors, address posted.
Certificate of Occupancy — Issued after all finals pass. DO NOT OCCUPY before this.
Permit Fee Estimation
Most jurisdictions calculate fees based on project valuation using ICC Building Valuation Data:
Construction Type $/sq ft (2025 BVD) Residential (Type VB, wood frame) $145-175 Commercial Office (Type IIB) $190-230 Retail (Type IIB) $155-185 Restaurant (Type IIB) $200-240 Warehouse (Type IIB) $95-120 Mixed-Use (Type IIIA) $175-215
Fee formula (typical):
Building permit fee: 0.5%-1.5% of project valuation
Plan review fee: 65% of building permit fee
Electrical/Plumbing/Mechanical: $50-200 each (flat) or % of sub-valuation
Impact fees: $2,000-$30,000+ (varies wildly by jurisdiction)
School fees: $2-5/sq ft in many CA jurisdictions
Park fees: $500-5,000 per unit (residential)
Fire sprinkler plan review: $200-1,000
Example — 2,000 sq ft house:
Valuation: 2,000 × $160 = $320,000
Building permit: $320,000 × 1% = $3,200
Plan review: $3,200 × 65% = $2,080
Electrical: $150
Plumbing: $150
Mechanical: $150
Total permit fees: ~$5,730 (before impact fees)
Permit Expiration Rules
Most building permits expire 180 days after issuance if work hasn't started
Active permits typically expire 180 days after last inspection
Extensions: 1-2 allowed, usually 180 days each, $50-200 fee
Expired permit = new application + new fees + current code compliance
Some jurisdictions have "sunset" provisions — 3-5 year max regardless of activity
Owner-Builder Considerations
Most states allow property owners to pull their own permits for personal residence
Owner-builder must sign affidavit (not hiring contractor, personal residence, not for sale within 1 year)
Still need licensed subs for electrical/plumbing/HVAC in many jurisdictions
Some states require owner-builder exam (FL, NV)
Resale disclosure required within 1-10 years depending on state
NO owner-builder permits for commercial projects
Red Flags That Trigger Extra Scrutiny
Project in flood zone (FEMA SFHA) — elevation certificate, flood-proofing, substantial improvement calc
Hillside/slope >15% — geotechnical report, special grading permit, retaining wall engineering
Near wetlands or waterways — environmental review, Army Corps Section 404, state buffer requirements
Historic district — preservation commission review, Secretary of Interior Standards
Wildfire zone (WUI) — fire-rated materials, defensible space, Class A roof
Seismic zone — enhanced structural requirements, special inspection requirements
Coastal zone — Coastal Commission review, setback from mean high tide
Contractor License Verification
Before pulling permits, verify your contractor's license:
California : cslb.ca.gov
Florida : myfloridalicense.com
Texas : tdlr.texas.gov (limited — TX doesn't license general contractors statewide)
New York : depends on municipality (NYC = DOB license)
National lookup : No single national database — each state is separate
Check: license status (active), insurance (current), bond (if required), complaints, disciplinary actions
When You DON'T Need a Permit (Usually)
Painting (interior/exterior, non-lead-based)
Flooring replacement (same level, no subfloor structural changes)
Cabinet replacement (no plumbing/electrical relocation)
Landscaping (no grading, no retaining walls over 4 ft)
Fencing under 6 ft (varies — some jurisdictions require permits for all fences)
Minor repairs (replacing fixtures, faucets, outlets in same location)
Window replacement (same size, same location, no structural modification)
When in doubt, call your local building department. Unpermitted work = liability, insurance issues, sale complications.
