Selling a mid-century modern home starts with a question every owner asks: what should I fix, and what should I leave alone? The answer isn't the same as it is for a typical house. Some repairs are tied to California's disclosure form and to the buyer's financing, while some features that can look dated, like wood paneling or a period color scheme, are part of what defines the architecture.
This guide sorts pre-sale work into three groups: items to address first, original features to keep, and the gray zone in between. It also covers the paperwork to gather and a way to pay for work before closing. It's general information, not legal advice, so take disclosure questions to a real estate attorney.
Start with the disclosure form and the buyer's lender
California's Real Estate Transfer Disclosure Statement includes certifications the seller makes as of the close of escrow. The seller certifies that the water heater tank is braced, anchored or strapped in place in accordance with state law, and that the home has operable smoke detectors that are approved, listed and installed. The form also has a checkbox for carbon monoxide devices.
The same form asks whether the seller knows of room additions, structural modifications, or other alterations or repairs made without necessary permits or not in compliance with building codes. It states that it isn't a warranty of any kind, and that buyers and sellers may wish to obtain professional advice and inspections of the property.
For homes built on or before January 1, 1994, state law adds a plumbing disclosure. The seller must disclose in writing the requirement to replace noncompliant fixtures and whether the property has any. Noncompliant means, for example, a toilet that uses more than 1.6 gallons per flush, a showerhead that flows more than 2.5 gallons per minute, or an interior faucet that flows more than 2.2 gallons per minute.
Then think about the buyer's lender. Fannie Mae's Selling Guide rates condition from C1 to C6. (Freddie Mac says the scale is unchanged on the redesigned appraisal dataset required for new reports since November 2, 2026, though the definitions were reworded.) A C5 home has obvious deferred maintenance and needs some significant repairs. A C6 home has substantial damage and isn't eligible as is; it must be repaired to at least C5 first. Anything that could push a house toward C6 belongs at the top of your list.
Fix first: items that tend to show up in reports
These items are tied to the disclosure form, to a pest or home inspection, or to the appraisal, so they're worth handling before you list:
Water heater strapping, smoke detectors and carbon monoxide devices. They're small jobs that line up with certifications on the disclosure form.
Active roof leaks. Palo Alto's Eichler design guidelines list flat roofs prone to leaks among owners' concerns. Fix the leak, then repair stains on exposed ceiling boards so they don't raise questions about whether it's still active.
Section 1 pest items. On a separated pest report, Section 1 lists active infestation or infection and damage from one. Ordering a report before listing lets you decide which items to complete. Beam ends, rafter tails and fascia boards are common places to look on a post-and-beam house.
Broken glass and stuck sliders. Glass walls are the heart of these homes, and a cracked pane or a door that won't roll is easy for a buyer to notice.
Heat that doesn't work. If the radiant system isn't heating, get a diagnosis so you can disclose accurately and decide whether to repair or offer a credit.
Noncompliant plumbing fixtures. You'll be disclosing them anyway, and replacing older toilets, showerheads and faucets is a contained project.
Leave alone: the features that define the house
Palo Alto's guidelines describe the elements that give these homes their character: walls that often feature mahogany paneling, radiant heating embedded in the slab, clerestory windows across the front, full-height glass at the rear, and plans organized around a center atrium. Pre-sale work should protect those elements, not erase them.
Wood paneling. Clean, repair and refinish it. Painting over original paneling is hard to undo, and it removes one of the house's defining materials.
The floor plan. Opening walls, closing an atrium or converting a carport right before a sale adds time, cost and permit questions without giving the next owner a choice.
Exposed beams and ceilings. Repair water stains and damaged boards rather than covering them.
Original hardware and fixtures. Clean and keep period light fixtures, cabinet pulls and built-ins that still work.
Our Eichler renovation guide covers which original features are worth restoring and which updates tend to be reversible.
The gray zone: paint, floors and kitchens
Paint. According to Palo Alto's guidelines, original exterior colors were earth tones with brighter accents on lintels, exposed carport beams and doors. A fresh coat in a period-appropriate palette can work well. In a home built before 1978, anyone paid to do work that disturbs paint must be certified under the EPA's Renovation, Repair and Painting program, so hire a certified firm.
Floors. The EPA lists vinyl floor tiles, the backing on vinyl sheet flooring and adhesives among materials that may contain asbestos. Don't tear out old tile before a sale without testing; cleaning and repairing it is usually the simpler move.
Kitchens and baths. A full remodel right before listing locks in your choices, and some buyers of architectural homes want to make their own. Repairs, new hardware and working appliances are a lighter alternative.
Landscaping. Clear plantings and soil away from siding and posts. The pest law lists earth-wood contact among conditions usually deemed likely to lead to infestation.
Gather the paperwork
Documents answer questions before they turn into negotiation points. Pull together:
Permit records from your city's building department, especially for additions, roof work and electrical upgrades.
Past pest reports. The Structural Pest Control Board lets you search whether a property was inspected in the last two years and request copies of inspection or completion reports.
Any inspection reports, roof warranties and receipts for heating, electrical or plumbing work.
Original plans, brochures or builder documents if you have them.
Our seller resources page covers the rest of pre-listing prep.
Paying for work before you sell
Pre-sale repairs and staging cost money before the sale brings any in. Compass Concierge lets sellers get fronted for the cost of home improvement services, such as floor repair, staging and interior and exterior painting, with zero due until closing. Depending on the state, fees or interest may apply, so read the terms. See our Compass Concierge page for how it works, and our home staging services for presentation.
Frequently asked questions
Should I paint over mahogany paneling before selling?
Generally, no. Palo Alto's Eichler guidelines note that walls often feature mahogany paneling, and it's one of the materials that define the style. Cleaning, repairing and refinishing it keeps the option open for the next owner.
Do I have to replace old toilets before I sell in California?
State law required owners of single-family homes built on or before January 1, 1994, to replace noncompliant fixtures by January 1, 2017, and sellers must disclose in writing the requirement and whether noncompliant fixtures remain. Ask a real estate attorney how it applies to your sale.
Should I get inspections before listing?
It can help. A pre-listing pest report lets you choose which Section 1 items to complete, and a general inspection shows what a buyer's inspector is likely to find. The disclosure form itself says buyers and sellers may wish to obtain professional inspections.
Do I have to fix every Section 1 item?
No. Who pays for Section 1 work is negotiated in the purchase contract. If an owner chooses not to correct a reported condition, the pest company isn't liable for damage caused by that choice, so weigh repairs against a credit with your agent.
