Title 24 planning in Simi Valley
Preparation guidance for energy compliance documentation in Simi Valley, California. Remote statewide service; local requirements come from your building department.
Hypothetical example / Simi Valley
A second-story addition changing the roof and duct location
Picture adding a second story while part of the existing roof becomes a floor assembly and ducts are relocated. Give the preparer sections showing what remains, what is removed and where the final thermal boundary runs. A floor-area summary alone will not explain the roof transition or the distribution changes. Record whether old equipment stays and which assemblies serve the added rooms. This Simi Valley example is an organizing exercise, not a structural recommendation or a claim about local addition requirements. Structural and mechanical design remain separate responsibilities.
Illustrative scenario only; not a statement about local projects, climate or permit rules.
Scenario checklist
- Provide existing and proposed sections
- Trace the final thermal boundary
- Show relocated equipment and ducts
- Tag removed and retained roof areas
Explain the assembly transition before modeling
Project-preparation guidance, not a statement of local requirements. Confirm applicability with your project team and reviewing agency.
Make the section readable
A section can reveal whether a space is enclosed, conditioned or adjacent to an attic. Pair each relevant assembly with a specification and mark unknown existing conditions. Ask the preparer which details are essential before finishing the construction drawings. Use the same assembly tags on sections and schedules so a relocated thermal boundary does not leave conflicting insulation notes behind.
Synchronize revisions across disciplines
If structural coordination changes a roof thickness, duct route or ceiling condition, notify the preparer rather than assuming the energy inputs are unaffected. Maintain an agreed final assembly schedule, and ask which installation or verification documents follow from the selected measures.

Is an energy report also a structural design for a second story?
No. The report documents its stated energy-compliance scope. Structural suitability, equipment design and other permit disciplines need their own qualified review.
Do you have an office in Simi Valley?
No. Service is remote and statewide; this page is a planning guide.
Where do I confirm Simi Valley requirements?
With the building department that reviews your permit. Many incorporated cities run their own; confirm whether Simi Valley or Ventura County reviews your parcel.

Start at Simi Valley’s city site for city department navigation; the county link provides separate county context.
The CEC climate tool supports a location-specific lookup; this guide assigns no climate zone. The CEC Energy Code Support Center separates edition-specific forms and building categories. Confirm the applicable edition, document family and any registration or verification requirements before using a form.
