California Building Code Compliance Check

A single missed code item can cost a 30–90 day correction cycle. BIDGRIT screens your scope against the California Residential, Electrical, Plumbing and Mechanical Codes before you submit, flags the items most likely to draw a correction, and tells you what to fix first.

The codes we screen

BIDGRIT checks your scope against the four codes that govern most residential work in California.

CRC — California Residential Code

Egress, light and ventilation, stairs and guards, smoke and CO alarms, structural and foundation requirements for one- and two-family dwellings.

CEC — California Electrical Code

Circuit requirements, AFCI/GFCI protection, panel and receptacle rules — where a surprising share of corrections originate.

CPC — California Plumbing Code

Fixture units, venting, water heater and gas requirements, and the clearances inspectors check first.

CMC — California Mechanical Code

HVAC sizing and placement, combustion air, duct and ventilation requirements for mechanical work.

Why pre-submission screening pays off

Plan-check corrections and failed inspections are expensive precisely because they are serial — each cycle restarts the clock. The items that cause them are predictable: missing egress, wrong AFCI/GFCI coverage, inadequate venting, smoke/CO alarm placement. Catching them before you submit turns a 30–90 day correction loop into a same-day fix.

Frequently asked questions

Which building codes apply to residential work in California?

Residential work in California is governed primarily by the California Residential Code (CRC), the California Electrical Code (CEC), the California Plumbing Code (CPC), and the California Mechanical Code (CMC). Local jurisdictions may adopt amendments on top of these.

What causes most plan-check rejections?

The most common corrections are predictable: inadequate egress, missing or mis-placed smoke and CO alarms, incorrect AFCI/GFCI coverage, insufficient plumbing venting, and HVAC sizing or combustion-air issues. Screening for these before submission avoids the correction cycle.

Can BIDGRIT guarantee my project passes plan check?

No tool can guarantee approval — local amendments and plan-checker discretion always apply. BIDGRIT screens for the common, predictable corrections so you can fix them before you submit; always confirm final requirements with your building department.
