Title and Deeds

Title refers to the ownership. Deed refers to the actual document noting the ownership.  A deed must be signed over and delivered to a buyer as well as recorded in government records.


State and local law often requires that residential property be retrofitted with various devices in order to bring them “up to code”.  The devices include smoke detectors, water conservation devices, and other safety or environmental protection devices or improvements.  It is customary for the seller to bear these upgrade costs –including new inspections, notifications, and reporting- prior to ownership transfer.    

Property Value Tax Reassessment

Under Proposition 13, real property is reassessed for property tax purposes only when a change in ownership occurs or when new construction is completed.  "New construction" is any improvement outside of normal maintenance. It does not mean only construction of a "brand new" building.

Non-Permitted or Non-Conforming Rooms, Additions, or Alterations

Buyers are advised to be cautious about properties that have been remodeled with new additions or significant alterations.  If these additions and alterations were made without permits they may be non-conforming and, if discovered by code enforcement officials, removed at the owners cost.  As such, before purchasing a home a buyer is encouraged to compare the actual building to the public records pertaining to the building and ensure that any additions or changes made to the building were done so according to building code and with the appropriate permits. 

Megans Law

Real estate sales contracts for property with 1-4 units as well as all rental or lease agreements are required to reference "Megan's Law".  In 1996, the California State Legislation required sex offenders to register with local and state agencies and require those agencies to release the available information about these sex offenders in an effort to create awareness and protect the public.  What does this mean? If you are selling a property, you have to disclose specific language in the purchase contract regarding the availability of the public information on any sex offenders. If you are buying a property (or renting or leasing an apartment), the seller or landlord should disclose to you in your agreement  that Megan's Law exists and that the information is available to you at a local government agency.  It is NOT their responsibility to inform you of any specific person that may or may not be residing in your neighborhood. They only have to inform you about the rule and state where you can find the specific information at your local government agency.
