Building Permits in California: A Complete Guide for Contractors

If you run a construction company in California, you already know that the permit process can make or break a project timeline. A job that should take six months can stretch to a year if plans are rejected, corrections pile up, or inspections are missed. And in a state with some of the most complex building codes in the country, the margin for error is thin.

This guide is written for construction professionals — contractors, project managers, and business owners — who want a clear picture of how the California permit process works, what the most common failure points are, and how to build a workflow that keeps projects moving.

Why California's Permit Process Is Different

California operates under the California Building Code (CBC), which is based on the International Building Code (IBC) but with significant state-specific amendments. The 2022 CBC is currently in effect, and it includes requirements that go well beyond the base IBC in areas like:

• Seismic design (California is in one of the highest seismic risk zones in the world)
• Energy efficiency (Title 24, Part 6 — one of the strictest energy codes anywhere)
• Fire-hardening (Chapter 7A for construction in high fire hazard zones)
• Accessibility (California Building Code Chapter 11B, which exceeds federal ADA requirements)

On top of the state code, every city and county can adopt local amendments. Sacramento County, the City of Sacramento, Elk Grove, Roseville, and other jurisdictions all have their own amendments that modify the base CBC. This means plans that work in one jurisdiction may need revisions for another.

The Permit Process: Step by Step

1. Pre-Application Meeting (Optional but Recommended)

For complex projects, a pre-application meeting with the building department can save significant time. You can present your project concept, identify potential issues early, and get guidance on submittal requirements.

Most Sacramento-area jurisdictions offer pre-application consultations. Contact the building department directly to schedule.

2. Plan Preparation

This is where most delays originate. Incomplete or non-compliant plans are the single biggest cause of permit delays in California.

What a complete residential permit submittal typically requires:

• Site plan (to scale, showing all structures, setbacks, utilities)
• Floor plans (all levels, dimensioned)
• Exterior elevations (all four sides)
• Building sections
• Foundation plan and details
• Roof framing plan
• Electrical plan (or deferred submittal by licensed electrician)
• Mechanical plan (or deferred submittal)
• Plumbing plan (or deferred submittal)
• Title 24 energy compliance documentation (CF-1R, CF-2R forms)
• Structural calculations (for new construction, additions, or significant structural work)
• Soils report (for new construction in many jurisdictions)

Common plan deficiencies that cause rejections:

• Missing or incorrect Title 24 energy compliance
• Inadequate structural detail for seismic requirements
• Setback violations (especially for additions and ADUs)
• Missing egress window specifications
• Incorrect fire-hardening details for Chapter 7A zones
• Incomplete accessibility compliance documentation

3. Plan Submittal

Most Sacramento-area jurisdictions now accept electronic plan submittal (ePlans). This has significantly reduced processing times compared to paper submittals.

Sacramento County: Uses ProjectDox for electronic plan review. saccounty.gov/building

City of Sacramento: Uses Accela for permit applications and plan submittal. cityofsacramento.gov/permits

Roseville: Uses EnerGov. roseville.ca.us/permits

4. Plan Check

After submittal, your plans go into plan check — the formal review process where building department staff verify compliance with all applicable codes.

Typical plan check timelines (as of 2025):

Jurisdiction	Standard	Expedited
Sacramento County	4–8 weeks	2–3 weeks (fee applies)
City of Sacramento	3–6 weeks	1–2 weeks (fee applies)
Elk Grove	4–6 weeks	2–3 weeks
Roseville	3–5 weeks	1–2 weeks

These are estimates — actual times vary based on project complexity and department workload.

5. Plan Check Corrections

It is rare for plans to be approved on the first submittal without any corrections. Most projects receive a correction letter (also called a "redline" or "comment letter") identifying items that must be addressed before approval.

How to handle corrections efficiently:

• Read every correction carefully — some are straightforward, others require engineering input
• Respond to every correction in writing, referencing the correction number
• If you disagree with a correction, request a meeting with the plan checker — many corrections can be resolved through discussion
• Resubmit promptly — delays in resubmittal extend your timeline

At Liberty Drafting Studios, we respond to plan check corrections within 3–5 business days as a standard practice. For urgent projects, we can often turn corrections around in 24–48 hours.

6. Permit Issuance

Once all corrections are resolved and fees are paid, the permit is issued. Do not start construction before the permit is in hand. Unpermitted work can result in:

• Stop-work orders
• Fines (up to $1,000/day in some jurisdictions)
• Required demolition of unpermitted work
• Difficulty selling the property
• Insurance claim denials

7. Inspections

Inspections are required at specific milestones during construction. The exact inspection sequence varies by project type, but for a typical residential addition or new construction:

1. Foundation/Footings — before concrete pour
2. Underground utilities — before backfill
3. Framing — before insulation or sheathing
4. Rough electrical, plumbing, mechanical — before walls are closed
5. Insulation — before drywall
6. Drywall — before taping (in some jurisdictions)
7. Final — when all work is complete

Inspection scheduling: Most jurisdictions allow online or phone scheduling. Schedule at least 24–48 hours in advance. Have the permit card and approved plans on-site for every inspection.

8. Certificate of Occupancy

After the final inspection passes, the building department issues a Certificate of Occupancy (CO). This is the document that legally allows the structure to be occupied. For rental properties, you cannot legally rent a unit without a CO.

How to Build a Permit-Efficient Workflow

After working on hundreds of projects across Greater Sacramento, here is what separates contractors who consistently hit their timelines from those who don't:

1. Hire your drafting professional before you sign the construction contract. Plans take time. If you wait until after the contract is signed to start plans, you are already behind.

2. Use a drafting firm that knows local jurisdictions. Every building department has its own quirks, preferred formats, and common correction items. A firm that has submitted dozens of projects to Sacramento County knows what the plan checkers look for.

3. Build correction response time into your schedule. Assume at least one round of corrections. Budget 2–3 weeks for the correction cycle.

4. Use permit coordination services for complex projects. For large projects or projects with tight timelines, having someone dedicated to managing the permit process — tracking status, responding to corrections, scheduling inspections — can save weeks.
