What to Expect When Getting a Building Permit in Sacramento County

If you're planning a home addition, ADU, remodel, or any significant construction project in Sacramento, you're going to need a building permit. For most homeowners, the permit process is unfamiliar territory — and that unfamiliarity leads to delays, extra costs, and frustration.

This guide demystifies the process. By the time you finish reading, you'll know what to expect, what to prepare, and how to move through the system as efficiently as possible.

Why Building Permits Exist (and Why You Should Care)

Building permits aren't just bureaucratic red tape. They serve a real purpose: ensuring that construction meets minimum safety standards for structural integrity, fire safety, electrical systems, and plumbing.

From a homeowner's perspective, permits also protect your investment. Unpermitted work can:

• Complicate or block a future home sale
• Void your homeowner's insurance for related claims
• Create liability if something goes wrong
• Result in costly legalization or demolition orders

Getting the permit right the first time is always cheaper than dealing with unpermitted work later.

What Projects Require a Permit in Sacramento?

Not every home improvement requires a permit, but most significant work does. In Sacramento County and the City of Sacramento, permits are generally required for:

• New construction (ADUs, additions, accessory structures)
• Structural changes (removing or adding walls, changing roof lines)
• Electrical work beyond simple fixture replacements
• Plumbing work beyond minor repairs
• HVAC system installations or major modifications
• Garage conversions and ADU conversions
• Decks over 30 inches above grade

Minor cosmetic work — painting, flooring, cabinet replacement — typically does not require a permit. When in doubt, call your local building department or ask a licensed drafting professional.

The Sacramento Building Permit Process: Step by Step

Step 1: Prepare Your Permit Documents

Before you can apply for a permit, you need a complete set of drawings. The building department will not accept incomplete submittals, and missing documents are one of the most common causes of delay.

For most residential projects, you'll need:

• Site plan — shows the property, existing structures, proposed work, setbacks, and dimensions
• Floor plans — detailed layouts of all affected spaces with dimensions and labels
• Exterior elevations — drawings of the building's exterior from all four sides
• Structural details — foundation plans, framing plans, and connection details
• Electrical, plumbing, and mechanical plans — required for projects involving those systems
• Title 24 energy compliance documentation — required for new construction and additions

These documents must be prepared to professional standards. Most homeowners work with a licensed drafting professional or architect to produce them.

Step 2: Submit Your Application

In Sacramento, you can submit permit applications in person at the building department counter or, for many project types, online through the jurisdiction's permit portal.

City of Sacramento: Permits are submitted through the SacConnect portal or in person at 300 Richards Blvd.

Sacramento County: Unincorporated county projects are handled through the County's online portal or at the Bradshaw Road office.

Other jurisdictions (Folsom, Elk Grove, Roseville, Rancho Cordova, etc.) have their own portals and counter locations.

At submittal, you'll pay an initial permit fee. The total fee is calculated based on project valuation and is typically paid in full when the permit is issued.

Step 3: Plan Check Review

After submittal, your plans go into plan check — a review by building department staff to verify code compliance. This is where most of the waiting happens.

Typical plan check timelines:

• City of Sacramento: 4–8 weeks for standard over-the-counter review; express review (additional fee) can reduce this to 1–2 weeks for eligible projects
• Sacramento County: 4–10 weeks depending on current workload
• Folsom, Elk Grove, Roseville: 3–8 weeks; varies by project complexity and department volume

During plan check, reviewers may issue correction comments — a list of items that need to be addressed before the permit can be issued. This is normal and expected on most projects.

Step 4: Respond to Plan Check Corrections

If corrections are required, your drafting professional prepares a written response addressing each comment and revises the drawings as needed. The corrected package is then resubmitted for a second review.

How many rounds of corrections should you expect?

On a well-prepared set of drawings, one round of corrections is common. Two rounds happen occasionally. Three or more rounds usually indicate a problem with the original drawings — either incomplete information, code violations, or unfamiliarity with local requirements.

This is why the quality of your initial drawings matters so much. A drafting professional who knows Sacramento's building departments and their specific preferences can dramatically reduce correction rounds.

Step 5: Permit Issuance

Once plan check is complete and all corrections are resolved, the permit is issued. You (or your contractor) pick up the permit and approved plans, which must be kept on-site during construction.

Step 6: Inspections During Construction

Building permits require inspections at specific milestones during construction. Your contractor is responsible for scheduling these, but it helps to understand what's involved.

Common inspection milestones include:

• Foundation inspection — before concrete is poured
• Framing inspection — after framing is complete but before insulation or drywall
• Rough electrical, plumbing, and mechanical — before walls are closed
• Insulation inspection — before drywall
• Final inspection — when all work is complete

Failing an inspection means the work must be corrected and re-inspected before you can proceed. Staying on top of scheduling and making sure work is ready before the inspector arrives keeps your project moving.

Step 7: Final Permit Sign-Off

When all inspections pass and the work is complete, the building department issues a final sign-off (sometimes called a Certificate of Occupancy for new structures). This document confirms that the work was completed in accordance with the approved plans and applicable codes.

Keep this document — it's important for future sales and insurance purposes.

Common Reasons for Permit Delays

After working on permit projects across Sacramento and surrounding counties, we see the same delay causes repeatedly:

Incomplete submittals. Missing a required document means your application is rejected at the counter or flagged during plan check. Always confirm the submittal checklist with the specific jurisdiction before you submit.

Drawings that don't meet local standards. Each jurisdiction has preferences and requirements beyond the state building code. A drafter unfamiliar with Sacramento's specific expectations will produce drawings that generate more correction rounds.

Slow correction responses. Plan check corrections have a response deadline. Missing it can result in your application being closed and requiring a new submittal. Respond promptly.

Contractor scheduling issues. Inspections must be scheduled in advance, and some jurisdictions have limited availability. Build inspection time into your construction schedule.

Scope changes mid-project. If you change the scope of work after the permit is issued, you may need to submit revised drawings for approval. Avoid scope changes if possible; if they're necessary, address them proactively with the building department.

How a Drafting Professional Helps

Navigating the permit process is much smoother when you have an experienced professional preparing your drawings and managing the submittal. Here's what a good drafting professional brings to the table:

• Local knowledge — familiarity with each jurisdiction's specific requirements, preferences, and quirks
• Complete, accurate drawings — reducing correction rounds and delays
• Correction response management — handling plan check comments professionally and efficiently
• Coordination — working with structural engineers, energy consultants, and other specialists when required
