Selling a House With Unpermitted Work in Nevada County, CA
You can sell a Nevada County home with unpermitted work, but you must disclose what you know on California’s Transfer Disclosure Statement. Your options are to disclose and sell as-is, legalize the work first through Nevada County’s after-the-fact permit process, or disclose and adjust price or terms. Unpermitted space can affect appraisals, insurance and buyer financing, so decide before you list.
What California requires sellers to disclose
For most sales of one to four unit homes, sellers complete the Transfer Disclosure Statement. It specifically asks whether there are room additions, structural modifications or other alterations or repairs made without necessary permits, and whether any are not in compliance with building codes. Disclose what you know, even if the work was done before you owned the home.
Common unpermitted items in the foothills
- Garage or shop conversions to living space
- Added bedrooms or bathrooms
- Decks and covered patios
- Outbuildings, sheds with power, and guest units
- Replaced water heaters, electrical panels or wood stoves without permits
Your three options
| Option | Pros | Cons |
|---|---|---|
| Disclose and sell as-is | No construction delay | Unpermitted square footage may not count in appraisals; some buyers and lenders will hesitate |
| Legalize before listing | Cleaner sale, stronger buyer pool, space can be valued | Takes time and money; may require opening walls or upgrades |
| Disclose and adjust price or credits | Lets the buyer handle permits | Buyers often discount more than the actual cost |
Nevada County’s after-the-fact permit process
Nevada County’s Building Department has a defined process for permitting existing work:
- A free consultation with staff and research into the property’s permit history.
- Establishing when the work was built, which sets the building code used for review.
- Plans comparable to a normal permit application, then the application itself.
- Plan check, which may call for engineer certification or exposing parts of the construction.
- A pre-inspection meeting, then inspections.
Under the county’s as-built policy, work is generally reviewed under the code in effect when it was built, while current life-safety items such as smoke alarms, egress and certain electrical protections are still required. Contact the Building Department at (530) 265-1222. Homes inside Grass Valley or Nevada City go through that city’s building department instead.
Seller tip
Pull your permit history before you list. Knowing exactly what is and isn’t permitted lets you price correctly and avoids a buyer discovering it mid-escrow.
