- Documents
- Visualization
- Structural engineer coordination
- Title 24 energy efficiency
- City submittal & plan check
- Approved, ready to build
Why it matters
The costliest correction is the one found after you submit
Most permit delays come from the same four problems. Each is cheap to fix on paper and expensive to fix later.
Caught at plan check
A setback nobody measured
The layout gets drawn first and the lot gets checked second. The city sends it back and the design starts over.
Caught at plan check
Sheets that disagree
The designer, engineer and energy consultant each work alone. Their sheets don't match, and the reviewer notices.
Caught on the calendar
Corrections nobody answers
A correction list arrives and sits while consultants pass it around. Every idle week pushes your permit out.
Caught on site
A plan that can't be built
Utilities, easements or an existing footing turn up after the permit. Now the fix is a change order.
Pricing
Three builds. One complete set.
Every package includes design plans, structural calculations and Title 24. Pick a build to see it.
Final fee depends on site conditions and city requirements. City permit fees are paid separately.

About the studio
20+Years of experience
Infinity DesignPro has 20+ years of experience producing permit plans side by side with structural engineers, for some of the top contractors in Southern California.
Your plans, structural and Title 24 are drawn as one coordinated set from day one, not stitched together from separate consultants. That means fewer surprises at plan check and plans your contractor can build.
- Engineer-coordinatedStructural design worked out with licensed engineers on every set.
- Contractor-testedDrawings built by top contractors across Southern California.
- One point of contactYou deal with one studio from site visit to permit.
Your options
Three ways to get a permit set
The drawings are the same in each. What changes is who coordinates them.
| Hire each consultant | Draw it yourself | Infinity DesignPro | |
|---|---|---|---|
| Contracts to manage | Designer, engineer, energy consultant, expediter | None for drawings, but you still hire the engineer and Title 24 | One |
| Site measure & as-built | Often a separate fee | You measure | Included |
| Sheets coordinated | Each consultant checks their own | You check all of them | One set, cross-checked before submittal |
| Plan check corrections | You forward the list between consultants | You answer them | We answer every item and resubmit |

FAQ
Questions owners ask first
Rules vary by city. We confirm yours before design starts.
How long does an ADU permit take?
On a lot that already has a home, California law gives the city 60 days to approve or deny a complete ADU application. Each round of corrections adds time, so a complete, coordinated first submittal is what shortens the wait.
How big can my ADU be?
State law caps a detached ADU at 1,200 SF. A city can set a lower limit, but not below 850 SF (1,000 SF with more than one bedroom), and every city must allow at least an 800 SF unit with 4-foot side and rear setbacks. Your lot, zoning and utilities set the real number. We check that at the site visit.
Can I convert my garage?
Usually yes. State law allows converting an existing garage into an ADU, and the city can't require you to replace the parking you lose.
Do I need a structural engineer?
Most cities ask for structural plans and calculations on new ADUs, additions and second stories. Simple conversions sometimes qualify without them. Our packages include the structural calculations, so you don't hire an engineer separately.
What is Title 24?
California's energy code. New ADUs and additions need a compliance report showing the insulation, windows, heating, cooling and water heating meet it. The report is included in every package.
What do you need from me to start?
The property ZIP code, what you want to build, and any plans or survey you already have. We measure the rest on site.
