Building Permits and Services Available in Altadena
Los Angeles County reviews construction activities according to the type of work, property zoning, and applicable building standards. Common permit categories include:

| New homes and additions | Building plans, zoning setbacks, structural requirements, utilities, and required agency clearances. |
| Remodels and structural repairs | Whether structural, electrical, plumbing, or mechanical systems are being altered. |
| ADUs and garage conversions | ADU zoning rules, existing structure conditions, utility connections, and building approvals. |
| Electrical, plumbing, and HVAC | Trade permits and inspections for covered installation or replacement work. |

Not every project requires every permit listed above. Some minor work may be exempt, while projects involving structural changes or regulated building systems can require multiple approvals. Verify requirements before purchasing materials or beginning construction.
Check Your Property’s Jurisdiction and Zoning
Altadena addresses are generally within unincorporated Los Angeles County. However, properties close to neighboring city boundaries should be checked individually, especially when a mailing address does not establish the permitting authority.
- Open the LA County GIS-NET Public mapping page.
- Launch the mapping application and search by street address or Assessor’s Identification Number.
- Review the property’s jurisdiction, zoning designation, and applicable overlays.
- Confirm any unusual boundaries, zoning conditions, or development restrictions with LA County Planning before applying.
Historic-resource restrictions, protected oak trees, fire hazards, and other parcel-specific conditions may affect what can be built.
How to Apply for an Altadena Building Permit Online
Los Angeles County uses the Electronic Permitting and Inspections system, known as EPIC-LA. Applicants can use this portal to submit eligible permit applications, communicate with reviewers, and manage active permit cases.
- Open the official portal. Visit EPIC-LA and select the registration or sign-in option. Create an account if you have not used the system before.
- Identify your project. Select the appropriate application category. For Eaton Fire reconstruction, use the County Recovery application rather than a routine construction application.
- Enter the property information. Provide the Altadena site address or parcel identifier, project description, and applicant details. Confirm that the system identifies the correct property.
- Upload your documents. Attach required plans and supporting materials. Fire-rebuild applications also require the applicable County recovery supplemental form.
- Submit and review the case. Check your information, submit the application, and retain the case number. Monitor messages and any requests for additional documents.
- Complete approval requirements. Respond to plan-review corrections, obtain necessary clearances, and pay applicable fees or complete eligible fee-deferral documentation before permit issuance.
Documents to Prepare Before Applying
Requirements depend on the project. A typical building application may call for a site plan, floor plans, elevations, structural details, scope-of-work description, contractor information, and supporting calculations. Larger projects may need energy compliance documents, soils reports, grading plans, fire access documentation, or other agency approvals.
For disaster-recovery applications, LA County specifically requires architectural plans and the appropriate in-person application or online supplemental form. The County provides these documents through its official rebuilding application guide.
Applying in Person
Applicants who need counter assistance can visit the Altadena One-Stop Permit Center during published hours. For Eaton Fire rebuilding, take architectural plans and the completed in-person application form. Staff can identify missing submissions and direct projects through the appropriate County departments.
How to Schedule Building Inspections in Altadena
Most permitted construction requires inspections at defined stages. Your issued permit and job card establish the inspections required for your project; the exact sequence depends on the approved work.
Request an Inspection Through EPIC-LA
- Sign in to your EPIC-LA account.
- Locate the issued permit associated with the property and construction work.
- Open the permit’s inspection options and select the required inspection.
- Submit the request and monitor the portal for confirmation or instructions.
- Make the approved plans, permit information, and work area available for inspection.
- Review any correction notice and request a follow-up inspection after deficiencies are resolved.
For County fire-rebuild projects, LA County states that an inspector confirms the inspection on the following business day and provides an inspection time. This describes the County’s published confirmation process, not a guarantee that every inspection will take place the next day.
| Inspection stage | Typical purpose |
|---|---|
| Foundation / footing | Check required excavation, reinforcement, and foundation work before concealment or concrete placement. |
| Framing | Verify structural framing and approved construction details. |
| Rough trades | Review applicable electrical, plumbing, and mechanical work before covering. |
| Insulation / energy | Verify required insulation and energy-related measures. |
| Final inspection | Confirm completion of applicable requirements before final sign-off. |
Additional fire, public-health, grading, or specialty inspections may be necessary. Do not conceal work until its required inspection has been completed or the inspector has authorized the next stage.

Altadena Eaton Fire Rebuilding Permits in 2026
The January 2025 Eaton Fire caused extensive property damage in Altadena. Los Angeles County established a coordinated rebuilding process involving Public Works, Regional Planning, the Fire Department, and Public Health.
For affected properties, the first major decision is whether a replacement project qualifies as a like-for-like rebuild or is considered a non-like-for-like rebuild.
Like-for-Like vs. Non-Like-for-Like Rebuilding
| Rebuild category | What it means in Altadena |
|---|---|
| Like-for-like | Generally replaces a legally established building in the same location and use. In the Eaton Fire area, qualifying modifications may increase floor area, size, height, or footprint by no more than 10% or 200 square feet, whichever is greater, subject to County rules. |
| Non-like-for-like | Projects outside the qualifying replacement limits are subject to current zoning and development standards and may require further planning review. |
The Fire-Rebuild Process
- Confirm debris clearance. The required hazardous-material and fire-debris removal phases must be completed before a rebuilding permit can be issued.
- Prepare replacement plans. Identify the pre-fire legally established structure, proposed dimensions, building location, and whether the project is like-for-like.
- Submit a County Recovery application. Use EPIC-LA or the Altadena One-Stop Permit Center. The County’s Unified Permit process coordinates reviews among participating departments.
- Address agency comments. Complete required zoning, structural, fire-safety, utility, and public-health reviews.
- Obtain the approved permit. Verify site clearance and any remaining conditions before beginning reconstruction.
- Complete inspections and final approval. Schedule inspections as construction progresses and obtain the required Certificate of Occupancy before moving into the completed replacement home.
For complete County disaster-recovery applications, the published expedited review target is a first review within 10 business days and subsequent reviews within 5 business days. These are review targets, not guaranteed permit-issuance times. Complex or non-like-for-like projects may take longer.
Temporary Housing and ADUs
Eligible disaster-affected households may be able to use a permitted RV, manufactured home, or mobilehome as temporary housing. Temporary units cannot be placed on an existing debris field, and additional site conditions apply.
Owners may also be able to pursue an accessory dwelling unit before replacing their primary residence. ADU applications must satisfy applicable standards, and fire-rebuild fee eligibility should be checked separately.
Building Permit Fees and Fire-Rebuild Fee Relief
Standard permit charges depend on the proposed work, project valuation, plan review, inspections, and any required agency approvals. A single fixed fee does not apply to every Altadena building project.
Who May Qualify for Eaton Fire Fee Deferrals?
LA County provides permit-related fee deferrals or refunds for qualifying owners rebuilding fire-damaged single-family homes in unincorporated County areas.
Generally, qualifying owners must have owned and occupied the affected property before January 7, 2025, and the project must meet the County’s fire-recovery criteria.
Eligible charges can include County zoning review, building plan review, building permit and inspection, fire review, and applicable public-health fees. However, private design and construction costs, utility charges, certain external-agency fees, and other excluded expenses are not covered.
Commercial properties, non-owner-occupied rental properties, multifamily buildings, and temporary housing projects do not qualify under the same single-family fee-deferral program.
How to Request Fee Relief
- Open the official County fee-deferral and refund page.
- Download the County’s Request for Fire Rebuild Fee Deferral or Refund form.
- Complete the eligibility declaration and project details.
- Email the form to recovery@planning.lacounty.gov or submit it at the Altadena One-Stop Permit Center.
- If qualifying fees were already paid, use the same form to request an eligible refund.
Building Codes Applicable in Altadena in 2026
California’s 2025 California Building Standards Code took effect January 1, 2026. Los Angeles County incorporates state building standards with locally adopted amendments through its County Code.
Depending on the project, applicable requirements may include:
- Los Angeles County Building Code — Title 26.
- County Residential Code — Title 30.
- County Electrical, Plumbing, and Mechanical Codes — Titles 27, 28, and 29.
- Applicable California Energy and Green Building Standards.
- Fire and wildfire-resilience requirements, including relevant wildland-urban interface provisions.
- County zoning standards under Title 22, where applicable.
The applicable code edition and amendments can depend on the application date and special fire-recovery provisions. Owners rebuilding older homes should not assume that all original construction details remain acceptable under current building and fire-safety requirements.
Official code source: California Building Standards Commission — Current Codes. County-specific requirements should also be confirmed with LA County Building and Safety.
Common Permit Problems and What to Do
| Problem | Practical next step |
|---|---|
| Incorrect permit jurisdiction | Check the parcel through County GIS-NET and confirm whether it is within unincorporated Los Angeles County. |
| Application marked incomplete | Review the portal’s correction request and submit the missing plans, forms, or property details. |
| Rebuild exceeds like-for-like limits | Ask County Planning whether revised drawings or non-like-for-like review is needed. |
| Debris clearance outstanding | Verify completion of both required debris-removal phases before expecting permit issuance. |
| Inspection not approved | Read the inspector’s correction notes, correct the work, and request reinspection. |
| Permit review taking longer than expected | Use the EPIC-LA case number to check pending comments or agency clearances, then contact the responsible office. |
