Fire Debris Removal and Clean-up
Let’s start with the very first step of rebuilding a home in Altadena; cleaning up the various debris and rubble remaining after the fire. As directed by the governor, the EPA and the Army Corps of Engineers have taken the lead on cleaning up the area by dividing the project into two phases.
Phase 1 – The EPA took charge of cleaning up the hazardous household waste on each burned property. According to California’s official fire rebuild tracking website, 99% of properties have already had phase 1 cleanup completed.
Phase 2 – The Army Corps of Engineers is taking the lead in removing all fire debris and related materials from each effected property. The started by asking each effected property owner to sign a Right of Entry form which allows them to enter your property and clean up the debris.
Altadena homeowners have the ability to opt-in or opt-out of this voluntary clean up program. According to the state website, over 98% of property owners have opted in to the Army Corps clean up program. Be aware: recovery momentum has picked up, and delays in cleanup could delay other phases of your rebuild.
Army Corps Debris Removal Details
According to the Army Corps of Engineers representative at the Altadena Town Council meeting, they are well underway in starting the cleanup efforts for property owners in Altadena. He expects to continue adding more clean-up crews to speed up the process to meet the goal of having most fire debris removed by January 2026.
According to Army Corps, their debris removal efforts will include disposing off all fire remnants on the property including cars, household items, dead or dangerous trees and everything within the “ash footprint” of the previous home. The ash footprint is defined as two feet outside the original building foundation of the previous home. In this area, they will dispose of all foundations, footings, chimneys, as well as 6 inches of dirt under the foundation.
According to Army Corps and other County representatives, there is no soils testing planned for the properties affected by the Eaton fire and soils testing will not be required by property owners to rebuild their homes. Army Corps does not intend to remove septic tanks or swimming pools. Their contractors intend to ‘smooth out’ the lot surface as much as possible, but they are not bringing in any dirt from offsite. So, there may be low areas or trenches on your site from areas of footing removals.
Update June 2005 – As of this date, Army Corps of Engineers has over 120 debris crews working to clear fire debris from sites in Altadena. Over 5000 properties have been cleared of fire debris. At this time, Army Corps expects to have all Altadena effected properties cleared by fall of 2025. You can call the USACE Los Angeles County Wildfire Debris Removal Mission hotline (213-308-8305) for the latest on your site.
Once Army Corps removes the debris and finalizes their work on each property, they relay this information to LA County Public Works. This department then validates the work has been completed and within a matter of 2 days to 2 weeks will provide the homeowner a ‘final property clearance’ which is the official acknowledgment that the property is ready for the start of any redevelopment or construction.
LA County Disaster Recovery Center
The Altadena Disaster Recovery Center (DRC) at 540 W Woodbury Rd closed permanently on May 31, 2025. Federal resources (FEMA, SBA) are now transitioning to other centers.
For rebuild help, survivors can now visit the One-Stop Rebuilding Center (1828 Sawtelle Blvd.) or the Altadena Community Center (730 E Altadena Dr.).
Power & Gas
According to Southern California Edison, all power has been restored to Altadena residents. As of April 2025, Edison staff has indicated that the CPUC has allocated $50M towards undergrounding electrical utilities in Altadena. At this time, there is no established plan for what sections will be undergrounded and when this will occur, but they intend to complete over 60 miles of Altadena service area. The entire process is expected to take 2-5 years to complete. However, Edison intends to provide power to any new homes completed via existing power lines.
SoCal Gas – As of Jan 31, 2025, Gas service has been restored to 7300 customers and their crews continue to work on restoring the remaining properties.
Water Service in Altadena
Water service in Altadena is provided by three different Mutual Water Companies. Before you start building, its important to contact the water company which serves your property to confirm they are ready and able to restore your water service. Because the fire may have damaged portions of the water infrastructure on your lot, such as the main water meter, its important to understand if they will require replacement of any elements.
Also, keep in mind that your new home will require fire suppression sprinklers and these will require an added level of water capacity & pressure, so make sure to inquire with your water company that they have sufficient ability to provide this.
Infrastructure plans are underway through the Altadena Wildfire Recovery Infrastructure Financing District (AWRIFD), which will help fund improvements in water systems, roads, and utilities, without raising new taxes for property owners. L.A. County Recovery
This could help rebuilding properties secure more stable water infrastructure in the long run.
Lincoln Avenue Water company
As of February 2025, their service is fully restored to all properties in their service areas. However, they are under a “boil water” notice until ongoing water testing reveals the water is safe to drink. According to their staff, 2600 of 4500 of their service connections (water meters) have been damaged and will need replacement or repairs. https://lawc.org/
Las Flores Water Company
As of February, 2025, they have not restored service yet and are waiting for approval of their water sampling plan by the state. They expect water sampling to start in March, with no specific visibility regarding a date for service to be restored. Staff indicated that they also have to do Fire Hydrant testing before any building permits will be issued. https://www.lasfloreswaterco.com/
Rubio Cañon Land and Water Association
As of February 2025, Rubio Canyon is still testing water and has sent reports to the state for approval. Their staff believe they are very close to restoring potable water service to their clients. https://www.rclwa.org/
LA County’s Expedited Process for “Like-for-Like Rebuilds”
The County created an expedited approval process for property owners who are planning to build homes that are similar in size and location to their previous structure. The deadline to opt-in or out has passed, but here’s some info:
These new homes will not need to be the same style, floor plan, or configuration. However, to qualify for expedited processing, the new home may not increase the size, height or building footprint by more than 10% over the original home.
The Disaster Recovery Center worked to build files for every property that indicate the specific details of the size and configuration of the original homes. Some older properties do not have good records, and it may be challenging to ascertain the exact size of the previous structures, especially including any additions over time. LA County and has permitted the start of new construction.
Altadena Zoning Code
Altadena residential properties may fall under one of several Zoning classifications set by LA County. A majority of Altadena homes fall under the R-1 zone while a few are within the R-2 zone. The maximum size of the home you can build on your property is calculated using the following formula: (Size of the lot x 25% +1,000sf).
The maximum height for these zones is limited to 30-35 feet, and 2 story maximum. The minimum yard requirements are as follows: 20 foot front yard, 25 foot backyard and 5 foot side yard setbacks from each respective property line. For homes up to 4 bedroom, 2 parking spots are required and for 5+ bedrooms, 3 parking spots are required.
There is growing interest in density under SB 9: since the fire, Los Angeles County has received several applications for density boosts through SB 9, allowing multiple units on single-family lots. For many rebuilding homeowners, SB 9 could be a tool to build ADUs, duplexes, or additional units, potentially increasing long-term value or rental options.
LA County Fire Department Requirements
LA County Fire Department has to approve all new home building plans submitted for plancheck.
Read Requirements: 2025 Eaton Fire Rebuild
One important thing to note is that the Fire Department will not allow you to receive a building permit until they can verify that your local hydrant meets their water flow requirements: 1,000 GPM for 1 hour at 20 psi residual pressure. Properties with residential fire sprinklers can have a reduced fire flow of at least 500 GPM for 30 minutes at 20 psi residual pressure. To determine whether your property meets this requirement, you must file Form 195 with the LA County Fire Department.
LA County Fees for Rebuilding in Altadena

In this area, philanthropic support is increasing. The Altadena Builds Back Foundation granted $4.55 million to support rebuilding for low- and fixed-income homeowners.
New California Building Requirements for Rebuilding
Before you begin designing your plans for a new home, there are a few important things to keep in mind with regard to current building standards and their cost implication. The California building code now has several standards that weren’t in place when your previous home was built. Specifically, all new homes require solar panels, interior fire sprinklers, an electrical-ready system for all electric appliances, and a ‘grey water ready’ plumbing system.
For homes in a designated High Fire Hazard Severity Zone, California regulations also require that homes meet the building code of Section 7A. This section requires flame and ember resistant materials for the exterior of the home, roof, windows, vents and surrounding vegetation, among other things.
The LA County Public Works and Building Departments have indicated that property owners who choose to rebuild may be required to upgrade the size of their main water line…the section that runs from the water meter at the sidewalk to the house. If the water main line was installed many years ago, it is likely to be undersized to serve a new home, especially one that is required to include fire sprinklers.
Its important to keep these building requirements in mind because they will impact your rebuilding budget. Your architect will know to integrate these requirements in your building plans, so you don’t have to worry about that. Your responsibility will be to work closely with your building contractor to understand the cost implication of these requirements on your rebuild budget.
Planning and Budgeting for your Altadena Rebuild
Alright, let’s look at the first step of building your dream home: planning and budgeting. Before you start spending any money, it’s important to do your homework. You’ll need to do make sure you have a good understanding of what you’ll be allowed to build, how much it will cost to build a home in Altadena, how long the homebuilding process will take, and any other questions that will help you plan for your new home project.
Start by visiting your local Disaster Recovery Center and the speaking to the County’s Building Department and Planning Department staff to learn about their restrictions and requirements. This will give you a clear idea of what they will and won’t allow you to build. Be sure to get a full list of the fees they’ll charge and ask about any new or unusual requirements for new home construction.
Next, it’s a good idea to talk to several architects and contractors in your area who have experience with new home construction. These experts can provide valuable insights into the building process, and many are willing to have an initial meeting or call with you for free. You’ll likely come away from these conversations with a much better understanding of what’s involved in building a home. GreatBuildz can connect you with vetted architects and builders in Altadena.
If you’re planning to finance your new home, now is the time to reach out to multiple lenders about construction loans. These loans differ from traditional mortgages in terms of rates, fees, and how funds are distributed. It’s important to understand how construction financing works and how to time your loan in relation to the other aspects of starting your new home build.
Developing Building Plans for your New Home
After completing your initial planning and due diligence, the next step in designing your new home is selecting the right architect. Begin by researching architects who specialize in home projects similar to yours. Evaluate potential candidates based on their experience, reputation, and familiarity with local zoning laws and building codes. GreatBuildz can connect you with a local Altadena architect.
Once you’ve chosen an architect, the design process typically begins with a series of conceptual floor plans. These initial sketches help visualize the layout and flow of your future home. Expect multiple iterations, as your feedback is essential to refining the design to meet your preferences and functional needs.
After finalizing the conceptual design, the architect will develop detailed building plans. This full set of documents includes specifications for materials, structural elements, and systems. A structural engineer may be involved to provide detailed designs for the foundation and framing. These detailed plans are essential for obtaining accurate construction bids.
With the detailed blueprints in hand, the next step is to submit them to the LA County building department for approval.
This plan check process involves a thorough review by building department staff to ensure the plans meet applicable building codes and regulations. It’s common for the building department to request revisions or additional information. Your architect will address these requests, making necessary adjustments to the plans. Once all comments are resolved, the building department will issue a permit, authorizing you to start construction.
The County of Los Angeles is allowing architects to develop Altadena pre-approved plans for residents to use when rebuilding after the Eaton Fire. These plans will be approved and available at this County website. GreatBuildz can you help you get accurate cost estimates for these Altadena pre-approved plans.
Bidding and Signing a Contract
As soon as you submit your plans for County approval, it’s go-time for gathering contractor bids. Don’t wait until you’ve got a permit in hand to start getting bids from builders. Start this process early because you need to know quickly if the quotes from builders match your budget. If bids come back way higher than expected, this is your window to tweak your plans to decrease the budget. Waiting until after permit approval to discover costs are too high means you’d have to redesign and resubmit everything, setting your project back by months.
However, hold off on signing any final contracts with your chosen builder until your plans get the County permit. Agreeing to terms based on preliminary designs can lead to headaches down the road if changes arise during the plancheck process. It’s best to finalize contracts once everything’s set in stone to avoid any frustrating renegotiations.
Construction
After all the planning and decision-making, your dream home is finally coming to life. It’s exciting to see the walls go up, but there’s still a long road ahead. Building a custom home usually takes about a year, and along the way, there will be plenty of choices to make and challenges to navigate.
One of the best things you can do is stay involved. Your builder will need your input on materials, colors, and finishes, basically, all the details that make the house feel like your home. You can tackle these choices yourself or bring in a designer to help, but either way, making decisions in a timely manner will help keep the project moving smoothly.
Once framing is done, plan to walk through your home every few weeks. These check-ins let you catch any issues early, whether it’s a small tweak to the layout or a fix that needs to be made. Making changes at this stage is much easier (and cheaper) than waiting until the end when things are already set in stone.
Final Steps & Getting Ready to Move In
Your custom home is finally complete, and you’re just a few steps away from moving in and enjoying your new space. But before you do, there are a few important things to take care of. First, do a thorough walk-through of the home and put together a punch list, a checklist of anything that needs fixing or finishing. No new home is flawless right off the bat, so this is your chance to catch things your builder should correct before you settle in. If you want extra peace of mind, you can even hire a home inspector to give everything a once-over and flag any issues.
Most reputable builders offer a limited warranty, so if anything goes wrong in the first year or so, they should take care of it. Be sure to ask about what’s covered and how to request repairs if needed. Next, you’ll need to get your Certificate of Occupancy from the builder. This is the official green light from the County that all inspections have been completed and you’re allowed to move in.
Then, don’t forget the practical stuff, setting up your utilities. Call your gas, electric, water, and trash providers to get service started. If you need internet, cable, or a home security system, now’s the time to get those scheduled too. Finally, line up your home service providers, landscapers, pest control, pool maintenance, and any other ongoing services you’ll need.
How Long Does it Take to Build a House in Altadena?
On average, building a home in Altadena takes 14 to 18 months, but the timeline can vary depending on the size and complexity of the project. It might feel like a long wait, but keep in mind that construction has to follow a specific order, with 20 to 30 different subcontractors handling everything from framing to plumbing to electrical. There aren’t many shortcuts when it comes to quality craftsmanship. Before construction even begins, you’ll need 3 to 6 months to finalize architectural plans, go through the city’s approval process, and secure a building permit.
Tips for Rebuilding a Home in Altadena
Your architect will focus on designing the home itself, but landscaping and outdoor spaces are just as important. If you want a stunning front yard, backyard, or hardscape, you’ll likely need a landscape architect or outdoor contractor to bring it all together. And don’t forget to budget for it, a well-designed backyard can easily cost over $200,000, even without a pool.
No construction project goes 100% according to plan. Delays and unexpected costs happen, and the best way to deal with them is to plan ahead. Most new builds experience 10-20% schedule delays and 5-10% cost overruns, so it’s smart to budget extra time and money upfront to avoid stress later.
Choose an architect that matches your vision. Some architects love designing homes that belong on magazine covers, but will that home feel comfortable for you? Make sure their style aligns with what you want. Look at their previous work and ensure they understand your needs, not just their artistic vision.
Bring in a Contractor early int the process. Architects design amazing homes, but they don’t always have the latest pricing info on materials and labor. Involve a contractor early on to get realistic cost estimates and identify areas where you can save money without sacrificing quality. A builder can also help “value engineer” your plans, making sure your budget goes toward the features that truly matter.
Costs to Rebuild a Home in Altadena
On average, building a home in Altadena costs between $400-$500 per square foot, but the actual range can vary from as low as $300/sq ft to over $800/sq ft. Every custom home is unique, and the final price depends on your specific choices. While overall square footage is a big factor, costs also increase with features like additional bathrooms, high-end cabinetry, custom flooring, or specialty finishes. The more details and upgrades you want, the more expensive your home will be.
The best way to determine the cost of your home is to consult with an experienced home builder and an architect. A builder can give you a realistic estimate based on your vision, while an architect can help design a home that aligns with your budget and priorities.
Make sure to speak with both your architect and contractor about other costs you might incur with rebuilding that aren’t included in the cost of the actual home. For example, will you need to rebuild property walls and fences, patio covers, backyard features, pool equipment, etc? And of course, don’t forget to budget for new landscaping.
