How to Detect Unpermitted Work on Any LA Property
Our unpermitted work checker cross-references the structures and square footage of a property against the official LADBS permit record. If we find a significant mismatch - a large addition, converted garage, or additional unit with no corresponding permit - we flag it as a potential unpermitted work indicator.
This tool is used by real estate investors, buyers, sellers, and attorneys to quickly assess permit risk before a transaction. It does not replace a full compliance inspection, but gives you a fast, free first read on any address.

Frequently Asked Questions - Unpermitted Work in LA
What happens if an inspector finds unpermitted work in LA?
If an LADBS inspector discovers unpermitted construction, they can issue a Stop Work Order, a Notice to Comply, or in serious cases a demolition order. You'll be required to either obtain a retroactive permit and pass inspection, or remove the unpermitted work. Fines can be assessed on a daily basis while the violation is open.
Can unpermitted work be legalized in California?
Yes, in most cases. California allows retroactive permits for work that meets current building codes. The process involves submitting as-built plans, paying permit fees (sometimes with a penalty multiplier), and passing inspections. Some work may need to be modified or partially demolished to pass. LA's ADU Amnesty Program also provides a streamlined path for unpermitted garage conversions and secondary units.
Does unpermitted work affect a home appraisal?
Yes - significantly. Appraisers are required to note unpermitted space and typically cannot count it toward the home's gross living area. An unpermitted 500 sf addition could reduce the appraised value by $50,000-$150,000 in the LA market. Read our full guide on how unpermitted work affects appraisal.
How much does it cost to legalize unpermitted work in LA?
Costs vary widely based on the type and extent of unpermitted work. A simple garage conversion legalization might cost $15,000-$40,000 all-in including permits and any required upgrades. A large unpermitted addition could cost $50,000-$150,000+ to bring into compliance. Contact CCS Inc for a free no-obligation assessment.
Should I disclose unpermitted work when selling in California?
Yes. California sellers are legally required to disclose known material defects, including unpermitted construction. Failure to disclose can result in post-sale lawsuits and liability. The safest approach is to legalize the work before listing or disclose it and adjust the sale price accordingly.
