The California Residential Purchase Agreement (RPA) is the most important legal document used when buying or selling a residential property in California. It defines the terms, conditions, rights, and obligations of both the buyer and the seller, and once signed, it becomes a legally binding contract.
This agreement is widely used by real estate agents, investors, homeowners, and attorneys across California.
What Is a California Residential Purchase Agreement?
A California Residential Purchase Agreement is a standardized contract—most commonly issued by the California Association of Realtors (CAR)—used for the purchase of residential properties, including:
- Single-family homes
- Condominiums
- Townhouses
- Small residential properties (up to 4 units)
It outlines how much is being paid, how the transaction will proceed, and under what conditions the sale can move forward or be canceled.
Why the Residential Purchase Agreement Is So Important
This agreement protects both parties by clearly stating:
- Purchase price and deposit
- Financing terms
- Inspection and contingency periods
- Closing timeline
- Responsibilities of buyer and seller
- Legal disclosures required by California law
Without a properly completed RPA, a real estate transaction in California can easily fall into disputes or legal issues.
Key Sections of the California Residential Purchase Agreement
1. Purchase Price and Earnest Money Deposit
The agreement specifies:
- The agreed purchase price
- The earnest money deposit amount
- How and when the deposit will be delivered (usually to escrow)
This deposit shows the buyer’s serious intent to purchase.
2. Financing Terms
The RPA indicates whether the buyer is using:
- Conventional loan
- FHA or VA loan
- All-cash purchase
It also includes loan contingency deadlines, giving the buyer protection if financing is not approved.
3. Contingencies
Contingencies allow a buyer to cancel the contract without penalty if certain conditions are not met, such as:
- Property inspections
- Appraisal value
- Loan approval
California RPAs are well known for having clear contingency timelines, which is critical in competitive markets.
4. Property Condition and Inspections
The agreement gives the buyer the right to:
- Conduct inspections (home, roof, pest, sewer, etc.)
- Request repairs or credits
- Accept the property “as-is” if agreed
California law strongly emphasizes full disclosure.
5. Required Disclosures
California has some of the strictest disclosure laws in the U.S. The RPA requires sellers to provide documents such as:
- Transfer Disclosure Statement (TDS)
- Natural Hazard Disclosure (NHD)
- Lead-based paint disclosure (for older homes)
- HOA documents (if applicable)
Failure to disclose properly can result in legal liability.
6. Escrow and Closing
The agreement sets:
- Escrow period (commonly 30 days)
- Closing date
- Who pays which closing costs
Escrow acts as a neutral third party handling funds and documents.
7. Possession and Final Walk-Through
The RPA defines:
- When the buyer gets possession (usually at recording)
- Buyer’s right to a final walk-through before closing
This ensures the property’s condition has not changed.
Who Should Use a California Residential Purchase Agreement?
This contract is essential for:
- Real estate agents and brokers
- Home buyers and sellers
- Property investors
- Real estate attorneys
- Real estate SaaS platforms and contract generators
Anyone involved in a residential transaction in California should use an up-to-date and state-compliant RPA.
Can You Use a Custom or AI-Generated Purchase Agreement?
Yes—as long as it complies with California law.
Many modern real estate professionals now use:
- Digital contract templates
- AI-powered contract generators
- SaaS platforms tailored to California real estate
However, it’s critical that the agreement:
- Reflects current California regulations
- Includes all mandatory disclosures
- Is reviewed before signing
