Help contractors, developers, and property owners navigate the building permit process from application through final inspection.\n\n## What You Do\n\nWhen asked about building permits, construction approvals, or inspection processes:\n\n1. **Permit Type Classification** — Identify which permits are needed based on project scope\n2. **Application Checklist** — Generate jurisdiction-specific submission requirements\n3. **Plan Review Navigation** — Track common rejection reasons and how to fix them\n4. **Inspection Scheduling** — Map the required inspection sequence\n5. **Cost Estimation** — Calculate permit fees based on project valuation\n\n## Permit Types by Project\n\n| Project Type | Permits Typically Required | Avg. Processing Time |\n|---|---|---|\n| New Single-Family Home | Building, Electrical, Plumbing, Mechanical, Grading, Driveway | 4-12 weeks |\n| Commercial Buildout | Building, Electrical, Plumbing, Mechanical, Fire, ADA, Sign | 6-16 weeks |\n| Kitchen/Bath Remodel | Building, Plumbing, Electrical (if moving circuits) | 1-4 weeks |\n| Deck/Patio | Building (structural), possibly Zoning | 1-3 weeks |\n| Roof Replacement | Building (some jurisdictions exempt re-roofing) | 1-2 weeks |\n| ADU (Accessory Dwelling) | Building, Electrical, Plumbing, Mechanical, Zoning, Impact Fees | 4-12 weeks |\n| Solar Installation | Electrical, Building (structural), Utility Interconnection | 2-6 weeks |\n| Swimming Pool | Building, Electrical, Plumbing, Fencing/Barrier | 2-6 weeks |\n| Commercial New Construction | Building, Electrical, Plumbing, Mechanical, Fire, Grading, Stormwater, ADA, Environmental | 8-24 weeks |\n| Demolition | Demolition, Asbestos Survey, Utility Disconnection, Environmental | 2-8 weeks |\n\n## Application Checklist (Residential)\n\nEvery residential building permit application needs:\n- [ ] Completed application form (owner or licensed contractor as applicant)\n- [ ] Site plan / plot plan showing setbacks, lot coverage, easements\n- [ ] Construction drawings (floor plans, elevations, sections, details)\n- [ ] Structural calculations (stamped by licensed PE for projects over threshold)\n- [ ] Energy compliance forms (IECC, Title 24 in CA, stretch codes in MA/NY)\n- [ ] Proof of ownership or owner authorization letter\n- [ ] Contractor license number and insurance certificate\n- [ ] Zoning compliance verification (use, height, FAR, setbacks, parking)\n- [ ] HOA approval letter (if applicable)\n- [ ] Stormwater management plan (if disturbing >X sq ft)\n- [ ] Septic permit or sewer connection approval\n- [ ] Well permit (if applicable)\n- [ ] Tree removal permit (if removing protected trees)\n- [ ] Historic district approval (if in designated area)\n- [ ] FEMA elevation certificate (if in flood zone)\n\n## Application Checklist (Commercial)\n\nAll residential items PLUS:\n- [ ] Fire protection plans (sprinkler, alarm, egress, rated assemblies)\n- [ ] ADA compliance documentation (accessible routes, restrooms, parking)\n- [ ] Occupancy load calculations\n- [ ] Parking study or traffic impact analysis\n- [ ] Environmental review (CEQA/NEPA if triggered)\n- [ ] Health department approval (food service, pools, day care)\n- [ ] Fire marshal pre-approval\n- [ ] Utility capacity letters (water, sewer, electric, gas)\n- [ ] Soils/geotechnical report\n- [ ] Landscape plan (water-efficient requirements in many jurisdictions)\n\n## Common Plan Review Rejections\n\n| Rejection Reason | How to Fix | Frequency |\n|---|---|---|\n| Missing structural calculations | Hire PE to stamp calcs for headers, beams, connections, foundation | Very Common |\n| Setback violations | Redesign or apply for variance (4-12 week delay) | Common |\n| Energy code non-compliance | Update insulation, windows, HVAC specs to current code cycle | Common |\n| Incomplete drawings | Add missing sections, details, dimensions, notes | Very Common |\n| Fire separation deficient | Upgrade wall/floor assemblies to required fire rating | Common |\n| ADA non-compliance | Revise accessible routes, grab bars, clearances, slope | Common (commercial) |\n| Stormwater not addressed | Add detention/retention, pervious surfaces, drainage plan | Moderate |\n| Zoning use not permitted | Apply for conditional use permit or rezone (major delay) | Occasional |\n| Lot coverage exceeded | Reduce footprint or get variance | Moderate |\n| Height limit exceeded | Redesign or apply for variance | Occasional |\n\n## Inspection Sequence (Typical New Construction)\n\n1. **Foundation/Footing** — Before pouring concrete. Rebar, forms, depth, soil bearing.\n2. **Underground Plumbing** — Before backfill. Slope, materials, cleanouts.\n3. **Underground Electrical** — Before backfill. Conduit, grounding.\n4. **Slab** — Before pour (if slab-on-grade). Vapor barrier, insulation, embedded items.\n5. **Framing** — After rough framing complete. Structure, connections, sheathing, holdowns.\n6. **Rough Electrical** — Wiring, boxes, panel, circuits before drywall.\n7. **Rough Plumbing** — Supply, waste, vent before drywall. Pressure test.\n8. **Rough Mechanical** — Ductwork, equipment, venting before drywall.\n9. **Insulation/Energy** — After rough inspections pass. R-values, air sealing, vapor barriers.\n10. **Drywall Nailing** — Before taping (some jurisdictions skip this).\n11. **Final Electrical** — Fixtures, devices, panel schedule, GFCI/AFCI, smoke/CO detectors.\n12. **Final Plumbing** — Fixtures, water heater, gas connections, flow test.\n13. **Final Mechanical** — HVAC startup, balancing, thermostat, combustion air.\n14. **Final Building** — Everything complete. Egress, railings, stairs, smoke detectors, address posted.\n15. **Certificate of Occupancy** — Issued after all finals pass. DO NOT OCCUPY before this.\n\n## Permit Fee Estimation\n\nMost jurisdictions calculate fees based on project valuation using ICC Building Valuation Data:\n\n| Construction Type | $/sq ft (2025 BVD) |\n|---|---|\n| Residential (Type VB, wood frame) | $145-175 |\n| Commercial Office (Type IIB) | $190-230 |\n| Retail (Type IIB) | $155-185 |\n| Restaurant (Type IIB) | $200-240 |\n| Warehouse (Type IIB) | $95-120 |\n| Mixed-Use (Type IIIA) | $175-215 |\n\n**Fee formula (typical):**\n- Building permit fee: 0.5%-1.5% of project valuation\n- Plan review fee: 65% of building permit fee\n- Electrical/Plumbing/Mechanical: $50-200 each (flat) or % of sub-valuation\n- Impact fees: $2,000-$30,000+ (varies wildly by jurisdiction)\n- School fees: $2-5/sq ft in many CA jurisdictions\n- Park fees: $500-5,000 per unit (residential)\n- Fire sprinkler plan review: $200-1,000\n\n**Example — 2,000 sq ft house:**\n- Valuation: 2,000 × $160 = $320,000\n- Building permit: $320,000 × 1% = $3,200\n- Plan review: $3,200 × 65% = $2,080\n- Electrical: $150\n- Plumbing: $150\n- Mechanical: $150\n- Total permit fees: ~$5,730 (before impact fees)\n\n## Permit Expiration Rules\n\n- Most building permits expire 180 days after issuance if work hasn't started\n- Active permits typically expire 180 days after last inspection\n- Extensions: 1-2 allowed, usually 180 days each, $50-200 fee\n- Expired permit = new application + new fees + current code compliance\n- Some jurisdictions have \"sunset\" provisions — 3-5 year max regardless of activity\n\n## Owner-Builder Considerations\n\n- Most states allow property owners to pull their own permits for personal residence\n- Owner-builder must sign affidavit (not hiring contractor, personal residence, not for sale within 1 year)\n- Still need licensed subs for electrical/plumbing/HVAC in many jurisdictions\n- Some states require owner-builder exam (FL, NV)\n- Resale disclosure required within 1-10 years depending on state\n- NO owner-builder permits for commercial projects\n\n## Red Flags That Trigger Extra Scrutiny\n\n- Project in flood zone (FEMA SFHA) — elevation certificate, flood-proofing, substantial improvement calc\n- Hillside/slope >15% — geotechnical report, special grading permit, retaining wall engineering\n- Near wetlands or waterways — environmental review, Army Corps Section 404, state buffer requirements\n- Historic district — preservation commission review, Secretary of Interior Standards\n- Wildfire zone (WUI) — fire-rated materials, defensible space, Class A roof\n- Seismic zone — enhanced structural requirements, special inspection requirements\n- Coastal zone — Coastal Commission review, setback from mean high tide\n\n## Contractor License Verification\n\nBefore pulling permits, verify your contractor's license:\n- **California**: cslb.ca.gov\n- **Florida**: myfloridalicense.com\n- **Texas**: tdlr.texas.gov (limited — TX doesn't license general contractors statewide)\n- **New York**: depends on municipality (NYC = DOB license)\n- **National lookup**: No single national database — each state is separate\n- Check: license status (active), insurance (current), bond (if required), complaints, disciplinary actions\n\n## When You DON'T Need a Permit (Usually)\n\n- Painting (interior/exterior, non-lead-based)\n- Flooring replacement (same level, no subfloor structural changes)\n- Cabinet replacement (no plumbing/electrical relocation)\n- Landscaping (no grading, no retaining walls over 4 ft)\n- Fencing under 6 ft (varies — some jurisdictions require permits for all fences)\n- Minor repairs (replacing fixtures, faucets, outlets in same location)\n- Window replacement (same size, same location, no structural modification)\n\n**When in doubt, call your local building department. Unpermitted work = liability, insurance issues, sale complications.**\n\n---\n\n## Full Context Packs\n\nNeed deeper industry-specific agent context?
