Permitted vs Unpermitted Work — 2026 LA Resale & Risk
In Los Angeles, the National Association of Realtors and multiple LA-market appraisal studies from 2022 through 2024 put the unpermitted-work resale discount at roughly 8 to 15 percent of total home value, depending on scope, visibility of the work, and the appraiser's methodology. Beyond resale, unpermitted work in LA creates three other downstream cost paths that most homeowners do not price in upfront: insurance claim rejection under CA Insurance Code §790.03 when damage traces back to unpermitted work, LADBS Code Enforcement retroactive permit fees at roughly double the standard permit fee plus required inspection and potential wall-opening, and loss of CA B&P §7031 protection if the contractor turns out to be unlicensed (which correlates strongly with willingness to skip permits). The CA B&P §7159 10% / $1,000 deposit cap still applies either way, but it does not retroactively convert unpermitted work into permitted work. Here is the full 2026 cost picture.
| Attribute | Permitted Work (LADBS) | Unpermitted Work |
|---|---|---|
| LADBS permit fee | Approx 1–2% of construction cost | $0 upfront — deferred cost at resale or discovery |
| Time to issue permit | 2–8 weeks typical (varies by scope) | N/A |
| Resale appraisal impact | Full scope appraises at market | Appraiser discounts 8–15% for unpermitted square footage (LA studies, 2022–2024) |
| Buyer discount at sale | None | 8–15% typical per LA real-estate practice |
| Homeowner insurance claim | Covered per policy terms | Insurer can deny claim if damage traces to unpermitted work (CA Ins Code §790.03) |
| Retroactive permit path | N/A — already permitted | LADBS Code Enforcement §98.0411: inspection + 2× standard permit fee + structural opening if needed |
| CA B&P §7159 protection | Applies (10% or $1K deposit cap, whichever less) | Applies to licensed work; unlicensed GC forfeits right to collect balance per CA §7031 |
| If GC is unlicensed | N/A | Homeowner can recover all payments already made (CA §7031(b)) — enforcement is litigation-heavy |
| Hillside / HPOZ / VHFHSZ risk | Permit process includes required reviews | LADBS can order demolition in HPOZ / hillside / VHFHSZ cases with no pre-approval |
| Best fit for | Any remodel you plan to keep, sell, or insure | (No defensible fit — the cost shifts, it does not disappear) |
Takeaway
The "save money by skipping the permit" argument almost never survives a 10-year hold horizon. You pay the 1–2% LADBS permit fee upfront, or you pay the 8–15% appraisal discount at resale plus the roughly 2× retroactive permit fee plus the potential insurance claim denial at the back end — the cost shifts in time, it does not disappear. For LA hillside lots under Ord 184081, HPOZ-designated properties, and Very High Fire Hazard Severity Zones (VHFHSZ), the risk tilts further because LADBS Code Enforcement under LAMC §98.0411 has authority to order demolition or reversal of non-compliant work with no pre-approval path. If you already have unpermitted work on your property — legacy additions from prior owners, converted garages, unpermitted ADUs — the retroactive legalization path exists, is well-trodden at LADBS, and is usually cheaper than losing the resale value. See /guides/unpermitted-work-legalization for NPLD's retroactive-permit workflow. The decision criterion: do you plan to ever sell, refinance, or make an insurance claim on this home. If yes, permit upfront.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
