Glendora Municipal Code

Determining Your Zoning

Glendora has several different single-family residential zones, each with different requirements.  The zoning map shows the zoning designation of every property.

Determining Your Property Lines

Property dimensions are usually visible on parcel maps available from the Los Angeles County Assessor.  To determine the exact location of your property lines with certainty, you must hire a licensed surveyor to survey your property.

Building Permit History

The building permit files for all properties in Glendora are available for public viewing in the Building Division.

Additions and Remodels

Remodels with no addition of square footage typically only require building permits, which are issued by the Building Division.  The Planning Department will review plans to ensure that all zoning requirements are met.  Additions must comply with all zoning requirements including setbacks and Floor Area Ratio, which determines the maximum size of a house.  This information is available on the single-family zones handout.  All two-story additions require approval from the Planning Commission through the Development Plan Review process.

Accessory Buildings

Recreation rooms, pool houses, storage sheds, detached garages, and other such accessory buildings are allowed in single family zones subject to certain limitations as listed on the single-family zones handout.

Accessory Dwelling Units / Guest Houses

Accessory Dwelling Units provide separate and independent living quarters and can be rented out on a long-term basis.  Guest Houses cannot be rented and are intended only for short-term stays by guests of the main house.  The summary handout highlights the differences between Accessory Dwelling Units and Guest Houses and outlines the requirements for each.

Home-Based Businesses

Home-based businesses, also known as home occupations, are allowed subject to certain restrictions as specified in the Glendora Municipal Code.  A business license issued by the Finance Department is required for all home occupations.
