A permit is the city or county reviewing the plan before work starts, then inspecting the work after it is built. Homeowners often experience permitting as friction. I see it as protection: for you, for the project, and for the value of the house.
Unpermitted work has a way of surfacing at resale, during an appraisal, or during an insurance claim, exactly when you least want to explain it. Permits do not make a project perfect, but they create a record and bring another trained set of eyes into the process.
What Usually Needs a Permit
Rules vary by jurisdiction, so treat this as the pattern, not a substitute for checking your city or county. A permit is commonly required when the work will:
- move or add plumbing, including relocating a fixture or drain
- add electrical circuits or upgrade the service panel
- alter, remove, or add walls
- change structural elements or the roof
- build an addition, convert a garage, or add an ADU
- change many windows or exterior doors, especially if the opening size changes
- replace or relocate water heaters, furnaces, or HVAC equipment
Cosmetic work in the same footprint may not require a permit. Paint, flooring, countertops, cabinet refacing, and fixtures swapped in place on existing connections are often simpler. When you are not sure, one call to the building department is worth making before you sign a bid.
Start With the Right Jurisdiction
The first question is who has authority over your address. If you are inside city limits, the city usually permits the work. If you are in an unincorporated area, the county usually does, even if your mailing address names a nearby city.
A quick way to confirm is to search your county assessor or parcel lookup for your address. You can also call the city building department and ask whether the property is actually in their jurisdiction.
Once you know the jurisdiction, look for the building or building-and-safety department. Many publish project handouts, submittal checklists, fee schedules, plan-check instructions, online permit portals, and local amendments to the code.
Over-the-Counter Permits Versus Plan Check
Small, well-defined work may be handled over the counter. You submit the required information, a plans examiner reviews it quickly, and the permit may be issued the same day or within a short window. A water heater replacement or a like-for-like reroof may be even simpler.
Larger projects usually go through plan check. The submittal is logged, routed to one or more departments, reviewed, and returned with comments. Comments are normal. The city may ask for clarification, a missing sheet, engineering, energy documentation, or details that were not obvious at first.
You respond, resubmit, and repeat until the project clears. Each round takes time, which is why permitting can quietly become the longest stretch of the schedule. Build the calendar around plan check, not the other way around.
What to Bring or Submit
The package depends on the scope, but a project that needs drawings may require:
- the plan set, either electronic or printed as required by the jurisdiction
- a completed permit application
- the property address and assessor parcel number
- structural calculations when structural work is involved
- Title 24 energy documentation when the work triggers it
- HOA approval if the jurisdiction requires it before submittal
- soils or geotechnical information for some hillside work, additions, or site conditions
- contractor license information once the contractor is selected
- payment for plan check, permit fees, or the first portion of them
For a simple permit, that list may shrink dramatically. Match the package to the work you are actually doing.
Title 24, HOAs, and Other Parallel Reviews
Title 24 is California’s energy code. Your designer, architect, engineer, or contractor should know when it applies and what documentation is needed. I have a separate article on Title 24 remodel requirements because it deserves its own explanation.
Your HOA, if you have one, is not the permitting authority. The HOA usually reviews appearance and community rules. The city or county reviews code, setbacks, safety, and permit requirements. Do the HOA approval early because some jurisdictions want that approval letter in the permit submittal, and an HOA can take weeks to respond.
Who Should Pull the Permit?
Usually the contractor pulls the permit under their license. That is the right default because it puts responsibility for the work on the licensed party performing or managing it.
A homeowner can pull a permit as an owner-builder, but that carries obligations most people do not want, including responsibility for the work and potential responsibility for people performing it. If a contractor asks you to pull the permit yourself so they do not have to, treat that as a flag, not a favor.
Inspections Are Part of the Permit
Inspections happen at stages. A project may have rough inspections when framing, plumbing, mechanical, and electrical work are open and visible, then a final inspection when the work is complete. The inspector confirms that the work matches the approved plans and meets code.
When several systems are ready at the same time, inspections can sometimes be coordinated so rough framing, rough electrical, rough plumbing, and similar items happen in a grouped visit. That can help the schedule, especially when walls cannot close until multiple approvals are complete.
But some inspections need to happen at a specific moment. A city may want to witness a shower pan or hot-mop water test, for example. The contractor, or you if you are managing the project yourself, should ask the inspector about expectations early. It is much better to know the inspection sequence before work is covered, tiled, or closed up.
Changes During Construction Can Reopen the Permit Question
A mid-project change can require the permit to be updated. Not always, but if the change touches structure, plumbing, electrical, or anything already inspected, ask before it is built. Inspectors would generally rather answer a question early than fail a final and require a wall to be opened back up.
Why This Belongs in the Planning Phase
Permitted work is documented work. It is something you can show a buyer, an appraiser, and an insurer without a story attached. It also gives the project a review path before the work becomes expensive to correct.
Master Build Advisor helps homeowners find out what the jurisdiction is likely to require before drawings are finalized. That way, the permit set and the bid set can support the same scope, and the schedule can allow for plan check from the start.
The objective is not more paperwork. It is fewer assumptions.
Your project. Your scope. Your decisions.
