Altadena Homeowner Guide: Eaton Fire Rebuilding, Permits and Selling

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team.

Altadena is an unincorporated community, so Los Angeles County, not a city, handles its permits, zoning and code rules, and the Eaton Fire that began on January 7, 2025 has made rebuilding rules the main local issue for owners. This guide covers how County rules apply in Altadena, what the County calls a like-for-like rebuild, how the Altadena Community Standards District fits in, and how all of it affects a sale.

Fire recovery programs change often, so confirm current details with the County before you act.

What the County means by a like-for-like rebuild

According to LA County Recovery, a like-for-like rebuild is a project with structures of the same size, in the same location and for the same purpose as the structures damaged or destroyed by the fire. Like-for-like structures can be smaller or have a different floor plan than the original.

In the Eaton Fire area, the County says a replacement can include modifications that do not increase floor area, size, height or building footprint by more than 10 percent or 200 square feet, whichever is greater.

The County also states that like-for-like structures do not have to meet current Zoning Code requirements, but they do have to comply with current Building, Fire, and Health and Safety Code requirements. That distinction matters for a buyer. A lot with a like-for-like path may be easier to underwrite than one that needs a redesign.

When the Altadena Community Standards District applies

The County says replacement structures that are not like-for-like must meet current Zoning Code requirements, and that in Altadena this includes the Altadena Community Standards District (CSD). It adds that some Zoning Code requirements may be modified for fire rebuilds.

For example, the CSD’s front yard setback requirements do not apply to non-like-for-like rebuilds, and the minimum required front yard setback for them is 20 feet. LA County Planning’s list of adopted CSDs includes Altadena, which earlier County records place in Chapter 22.306 of Title 22, adopted in 1998.

I did not retrieve the full current CSD text, so check the Title 22 chapter before you plan a larger or different home.

The rebuild steps the County describes

LA County Recovery lays out four steps: site clearance and plan submission, permits, construction and inspections, and move-in. Site clearance includes household hazardous debris removal and fire debris removal before plans are submitted.

The County lists LA County Planning, Building and Safety, Fire, and Public Health as the reviewing agencies, with the U.S. EPA and U.S. Army Corps of Engineers involved in debris removal.

LA County Planning also says it offers pre-approved standard plans for fire rebuilds and does not charge a Planning fee for them. I did not confirm current building permit fee reductions, so ask the County what applies to your parcel.

Temporary housing and ADUs on fire-damaged lots

LA County Planning defines temporary housing as use of a recreational vehicle, manufactured home or mobilehome on a property where a legally established single-family home, accessory dwelling unit or caretaker’s residence was destroyed or made uninhabitable by a disaster.

The agency’s list of adopted ordinances shows an Eaton Fire disaster interim ordinance and an ADU ordinance amendment. I did not retrieve their text, so confirm the current ADU size, height and fee rules with County Planning before you design a unit.

Selling an Altadena lot or damaged home

Owners facing a rebuild have three broad choices: rebuild, sell the lot or damaged structure, or sell and let a buyer take on the process. A buyer who pays cash is not waiting on a lender’s appraisal of a rebuild.

Before you decide, gather your insurance claim documents, any debris-removal records, the permit history of the structure that stood there and the parcel number, and ask the County whether your property qualifies as like-for-like. Insurance and tax treatment can be complicated, so talk with your insurer and a tax professional. Our Prop 13 guide explains reassessment basics.

Permits and selling an Altadena house

Buyers and lenders ask about permit history, and California sellers generally disclose known unpermitted work on the Transfer Disclosure Statement. Our guide to selling as-is with unpermitted work explains what disclosure involves, and the seller closing costs guide shows what else to budget. If tenants live in the home, read the tenant-occupied home sale guide.

When an Altadena home has an open permit, an expired one or work done without a permit, you generally have three options: finish and finalize the permit before listing, disclose the work and negotiate on the open market, or sell as-is to a cash buyer who takes the house in its current condition. Use this checklist:

• Ask the permitting agency for the permit record on your address.
• List every addition, garage conversion, enclosed patio or outbuilding, and note which have permits.
• Gather final inspection records, plans and contractor invoices.
• Ask what plans, fees and inspections it would take to permit each unpermitted item.
• Compare that cost and time with a no-repairs cash sale. New construction can also be reassessed for property tax, which our Prop 13 guide explains.

Code enforcement and open violations

An open notice does not stop you from selling. California sellers generally disclose known notices on the Transfer Disclosure Statement, and a title search will show any recorded lien.

Sellers with open violations usually choose one of three paths: correct the problem and ask the agency to close the case before listing, disclose it and sell with a price adjustment, or sell as-is to a cash buyer who takes on the cleanup. Before you decide:

• Get the case number, notice date and the specific code sections cited.
• Ask the agency what must be done to close the case and whether it will re-inspect.
• Ask for a current statement of fines and fees, and whether a lien has been recorded.
• Get quotes for the work so you can compare repair cost with a no-repairs sale.
• Check whether tenants, an estate or a co-owner need to be part of the decision.

The costliest mistake is ignoring a notice. Appeal deadlines are short, fines and fees can escalate, and unpaid costs can end up as a lien that follows the property. Keep every notice, photo and receipt, and write down the name of each staff member you speak with. If the home came to you through an inheritance, our probate home sale guide and inherited home tax basis guide cover the basics.

State ADU law and Altadena

California’s ADU statute, Government Code section 66314 and following, sets a floor that every local government must follow.

The state generally requires ministerial review within 60 days of a complete application, limits the standards a local agency can impose, and generally allows an ADU or conversion inside existing space without added setbacks. The California Department of Housing and Community Development (HCD) publishes a handbook of the state requirements.

I did not confirm the current County ADU ordinance text, size limits or fee amounts for this guide, so ask County Planning for the current handout before you design anything.

Many older homes have a converted garage or a backyard unit built without permits. Buyers and lenders ask about them, and an appraiser may not count unpermitted space.

A junior ADU is a unit of up to 500 square feet created inside an existing or proposed single-family home, with an efficiency kitchen and a recorded restriction. New construction can be reassessed under Prop 13, so an ADU may raise the tax bill for the whole property.

Before you list, check records for permits on any ADU or conversion, ask Planning whether the structure could qualify under current rules, and compare the cost of legalizing it with selling as-is.

Property tax and recording when you sell

Property in Altadena is taxed by the County, and a sale triggers a deed recording and, generally, a documentary transfer tax. See our Los Angeles County property tax guide for supplemental bills and proration, and the Recorder and deed transfer guide for recording. If the owner has died, the probate and inherited home guide explains the usual path.

What is a like-for-like rebuild in Altadena?

The County defines it as a structure of the same size, in the same location and for the same purpose as the one the fire damaged or destroyed. In the Eaton Fire area, modifications up to 10 percent or 200 square feet, whichever is greater, are allowed.
