Permits feel like bureaucracy until you're the one buying, selling, insuring, or repairing a house where somebody skipped them. Here's the practical version for Los Angeles homeowners.
No permit needed
- Paint, inside and out
- Flooring (carpet, LVP, hardwood replacement)
- Cabinets and counters in the same layout
- Minor drywall patches and repairs
- Fences under 6 ft, most low garden walls
- Like-for-like fixture swaps (faucet, toilet in the same spot)
Permit required
- Anything structural: walls (even "just one wall"), beams, roof framing, balconies
- Additions, ADUs, and garage conversions
- New electrical circuits, panel upgrades, rewires
- Water heaters — yes, really — plus repipes and sewer replacement
- Windows changing size or fire-escape (egress) requirements
- Re-roofs, new HVAC, gas lines
- Retaining walls over ~3–4 ft or holding weight above
Who you deal with
City of LA neighborhoods (most of the Valley, South LA, Central LA) go through LADBS. Independent cities — San Fernando, Burbank, Glendale, Inglewood, every Orange County city — run their own counters with their own quirks. Simple scopes are often issued same-day over the counter; additions and ADUs go to plan check, typically 4–8 weeks depending on the city and season.
What skipping permits actually costs
- At sale: unpermitted space gets discounted or demanded fixed in escrow, and sellers must disclose it.
- At claim time: insurers deny fire and water claims traced to unpermitted electrical and plumbing.
- At code enforcement: a complaint can bring an order to open walls, redo the work to current code, and pay penalty fees — the job costs double the second time.
- At refinance: appraisers can't count square footage the county doesn't know exists.
What it looks like when it's done right
A licensed contractor designs to code, pulls the permit, meets the inspector at each stage — foundation, framing, rough plumbing and electrical, insulation, final — and hands you a finished project with a paper trail. That trail is worth real money: it's proof your square footage, systems, and structure are legal and insurable.
