Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
The County's current Codes and Ordinances page states that the 2022 California Building Standards Code updates are in effect, covering building, electrical, plumbing, mechanical, energy, fire, and life-safety requirements, together with San Luis Obispo County Building and Construction Ordinance Title 19, land-use/subdivision ordinances, including Title 26 Growth Management Ordinance, and applicable County Fire requirements.
Inspection lane
Use the PermitSLO portal to schedule inspections; requests must be received by 5:00 p.m. the day before the requested date. A permit-holder or contractor with a valid County construction or grading permit may schedule, and the inspector provides a two-hour arrival window. Inspections are generally Monday-Friday, with limited area-specific days; permitted work must be inspected before it is covered or concealed. Permit/inspection phone: (805) 788-6602.
Minor-work playbook
The County specifically documents an agricultural accessory-building exemption under Title 19 when the structure meets the applicable California Building Code agricultural definition and the County's Title 19 Section 19.02.020(f) criteria. The exemption authorizes the exempt agricultural use only; separate construction or grading permits may still be required. N/A for a general County-published minor/cosmetic exemption list.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Use the PermitSLO portal to schedule inspections; requests must be received by 5:00 p.m. the day before the requested date. A permit-holder or contractor with a valid County construction or grading permit may schedule, and the inspector provides a two-hour arrival window. Inspections are generally Monday-Friday, with limited area-specific days; permitted work must be inspected before it is covered or concealed. Permit/inspection phone: (805) 788-6602.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
San Luis Obispo County Department of Planning & Building is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Planning & Building (805) 781-5600; permits/inspections (805) 788-6602; Code Enforcement Hotline (805) 788-2350.
N/A for ordinary plan review; the County publishes a seven-phase workflow rather than a single typical approval time. Subsequent completeness-check cycles typically take 1-3 days; applicants have 10 business days to resubmit an incomplete package and 15 calendar days to pay intake or plan-review invoices.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
