Short answer: Title24Comply is an online Title 24 service for California building permits. You choose your report type, enter project details, upload your plans as a PDF and pay securely online. We model the project in CEC-approved compliance software and email a permit-ready report, typically in 2–3 business days. Reports start at $199 for ADUs, $245 for single-family residential and $345 per building for multifamily.
What a Title 24 Service Includes
A Title 24 report shows your building department that the design meets California's Building Energy Efficiency Standards (Part 6 of Title 24). Every report we prepare follows the same core process:
- Plan review — we check the scope, square footage and the documents you uploaded.
- Energy modeling — the design is modeled in CEC-approved software using the project's climate zone, envelope, windows, HVAC and water heating. The model is compared with a code-defined standard design for the same building.
- Quality review — the model and forms are checked and signed before delivery.
- Registration — where the project requires it, the report is registered with the CHEERS data registry.
- Delivery — a permit-ready PDF by email, with two revisions included.
For most single-family homes and ADUs the compliance document is the CF1R; low-rise multifamily projects use the LMCC.
Title 24 Services by Project Type
ADU Title 24 reports
Detached, attached and junior ADUs usually need an energy report before the permit is issued. ADU Title 24 reports start at $199 for up to 1,000 sq ft.
Residential (single-family) reports
Residential Title 24 reports cover single-family homes, remodels that change conditioned space and larger alteration projects. From $245.
New construction
A new home is modeled as a whole building, including mandatory measures and solar PV where it applies. See new construction Title 24.
Home additions
Room and second-story additions are usually modeled either on their own or together with the existing house. See home addition Title 24.
Garage conversions
Turning a garage into living space creates new conditioned area, which normally triggers Title 24. See garage conversion Title 24.
HVAC and window replacements
Many alterations need documentation too. We prepare reports for HVAC replacements, including heat pump changeouts, and for window replacements, depending on scope and what your building department asks for.
Multifamily
Multifamily Title 24 reports cover duplexes, triplexes, fourplexes and larger low-rise buildings, priced per building from $345.
Commercial
Nonresidential projects are priced by custom quote because scope, building type, conditioned area, compliance method, and mechanical and lighting systems vary widely. Request a commercial quote — we typically reply in about 5–15 minutes during business hours.
Working With a Title 24 Consultant
A Title 24 consultant (also called an energy consultant or documentation author) turns your plans into an energy model and the compliance forms your building department reviews. The responsible designer on the project signs the documents alongside the consultant. Good results depend on clear inputs, so it helps to send:
- Floor plans, elevations, sections and a site plan showing orientation
- A window schedule with sizes and, if chosen, the product ratings
- Wall, roof and floor assembly details and insulation
- HVAC and water-heating equipment, if already selected
See what documents to upload for the full list. Preliminary plans are fine for many projects; if the design changes later, we can update the report. When plan check returns comments on the energy documents, the two included revisions cover typical plan check corrections.
Because the work is done from plans, you do not need a site visit or a local office. Title24Comply works with projects statewide across all 16 California climate zones.

Frequently Asked Questions
Do I need an engineer for a Title 24 report?
Usually not for typical residential work. Title 24 energy documentation for homes, ADUs, additions and alterations is generally prepared by an energy consultant and signed by the responsible designer; a licensed engineer is not normally required for it. Some nonresidential projects may need a licensed professional's signature, so check with your building department if your project is commercial.
Which Title 24 service do I need?
Pick the option that matches your permit scope: ADU, residential (single-family, additions, garage conversions, alterations) or multifamily. If you are unsure whether your project needs a report at all, see when Title 24 is required.
How long does a Title 24 report take?
Standard turnaround is 2–3 business days after we receive complete plans, with next-day and same-day rush options.
Is the report a field inspection?
No. The report is prepared from your plans. Your building inspector and, where required, a HERS rater verify the work in the field later.
