Whittier Building Permits Guide for Homeowners and Sellers

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team. Information comes from the City of Whittier Building and Safety pages; sources are listed at the end.

Whittier keeps scanned copies of many issued permits in its online document archive, which makes it easier than in many cities to check a house’s permit history before you list. A buyer’s inspector or lender may find a mismatch, so it helps to find it first.

Whittier building permits at a glance

When does Whittier require a permit?

The city says permits are required to build, construct, enlarge, alter, repair, move, improve, remove, convert or demolish a building, and for most plumbing and electrical improvements. The FAQ lists one-story detached tool or storage sheds and playhouses as exceptions when they meet the conditions it states, so read the FAQ before assuming a structure is exempt.

How do I look up permits on a Whittier property?

Use the Accela portal for permit status, and search the City Clerk’s Online Document Archive for scanned permits. Look for permits opened but never finaled, work you know was done that has no permit, and additions that do not match the original plans.

How permits affect selling a house in Whittier

Permit problems usually surface when a buyer’s inspector or lender asks whether finished space was legally built. In California, sellers generally must disclose known problems, including work you know was done without a permit. On a traditional listing, the usual choices are to finish the open permit, permit the work after the fact, lower the price, or give a credit.

How to sell a house in Whittier with unpermitted work or open permits

1. Pull the permit history first.
2. Write down what you know: who did the work, when, and what receipts or plans you have.
3. Compare options: fix it, sell with a credit, or sell as-is to a cash buyer.
4. Disclose honestly. A cash offer does not change disclosure duties but removes repair steps.

Which Whittier projects need a permit, and which do not?

The city’s Building and Safety FAQ is more specific than most. It says a building permit must be issued before work starts to erect, construct, enlarge, alter, move, improve, remove, convert or demolish any building or structure, and that electrical, plumbing or mechanical permits may also be needed.

The examples it gives are useful when you are trying to work out whether a past owner’s project was done properly:

• Permit required: patio covers, window replacement, water heater replacement, air conditioner condenser replacement or new installation, roofing and re-roofing, demolition, footings for a future patio cover, wood or vinyl fences over 18 inches high, block walls 18 inches or taller, and retaining walls of any height.
• No permit required: a one-story detached tool or storage shed, playhouse or similar building with a floor area of 120 square feet or less (though Planning still reviews its location), a patio or driveway slab, painting, wallpaper, carpet or flooring, window coverings, and garage sales.
• Driveways: they need approval from the Planning Division and a driveway approach permit from the Engineering Division of Public Works.

How long Whittier plan check takes

For projects that need plan review, the FAQ explains the usual path. Typically four sets of plans are submitted. The plan reviewer picks up and delivers plans on Wednesday mornings, and the review usually takes about two weeks from the Wednesday after submittal.

When plans come back with corrections, you resubmit the marked-up originals plus three new sets, and rechecks usually take about one week. The plans then go to the Planning Division for final approval, after which Building and Safety tells you the permit is ready to issue.

The city lists the drawings that may be required, including site plan, floor plan, elevations, foundation and framing plans, cross sections, energy calculations and structural calculations. If you are selling and need to resolve an open item, build these weeks into your timeline.

Permit expiration and final inspection in Whittier

Two rules in the FAQ matter a lot to sellers. First, a building permit remains valid for 180 days from the date it is issued, and each time the project passes an inspection on the city job card the expiration date extends to 180 days from that inspection.

If work has stalled, you can request a 180-day extension in writing with a timeline. The city also says exterior improvements must be completed within 24 months of permit issuance.

Second, a final inspection is required on every building permit, and the city says it is ultimately the property owner’s responsibility to make sure the final happens. Failing to get a final can lead to withholding approval of future permits.

For permits over $1,000 in value, the final also checks that smoke detectors and carbon monoxide sensors are installed where the California Building Code requires them.

If you bought a house where a previous owner started a project and never finished it, an expired or unfinished permit may still sit in the city’s records. That is one of the first things to look for.

Owner-builders: who can pull permits and the catch for sellers

The city defines an owner-builder as a homeowner who acts as the general contractor, lives at the work site as a principal residence for 12 months before completion, and does not build and sell more than two structures in any three-year period.

Owner-builders pull all building permits and sign the state’s owner-builder forms. The city also says anyone who contracts for work valued at $500 or more in labor and materials must hold a current license from the Contractors State License Board.

The city’s warning about the risks includes costly mistakes, liens from unpaid suppliers, and liability for injuries when workers are unlicensed or uninsured. If a past owner did major work themselves, ask for the permit records and final inspection sign-offs, because a buyer’s lender will want them.

Inspections, hours and school fees

Inspections can be requested by phone at (562) 567-9320, online through the city’s permit and inspection portal, or at the counter.

The city says to call at least one business day ahead, give the permit number and job address, provide full access (including a ladder for roof work) and have an adult present. The cutoff for next-business-day requests is 3:00pm.

Construction activity, including preparation, cleanup and material delivery, is allowed from 7:00am to 9:00pm Monday through Friday and from 9:00am to 9:00pm on Saturdays, Sundays and legal holidays. The city’s pages list slightly different counter hours in different places, so confirm before you visit.

Permit fees are based on construction valuation, and school district development fees apply to construction of 500 square feet or more, paid before the permit is issued; the FAQ lists a per-square-foot rate for each school district that serves the city.

What buyers and lenders look at in Whittier

Under California Civil Code section 1102.1, selling as-is does not waive delivery of the transfer disclosure statement, and your duty to disclose material facts that affect value stays in place.

A patio cover, new water heater, converted garage or finished attic that has no permit is something to raise with your agent or escrow officer.

Disclosure timing is covered by section 1102.3: a buyer who gets a required disclosure after making an offer can cancel within three days of in-person delivery or five days of mailing or agreed electronic delivery.

Search the city’s online document archive first, ask Building and Safety about anything open, and decide whether to finish the paperwork, credit the buyer, or sell as-is.
