West Covina Zoning and ADU Guide for Homeowners and Sellers

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team. Information comes from City of West Covina public records on its ADU ordinance; those documents may predate later changes, so sources are listed at the end.

West Covina allows accessory dwelling units in residential zones, subject to a building permit. The city’s records also show it has had to bring its ordinance in line with changing state ADU law, so confirm current rules with the city before you act.

West Covina ADU rules at a glance

Can I build an ADU in West Covina?

Generally yes in residential zones, with a building permit. The city’s records note that the state Department of Housing and Community Development reviewed the ordinance and found items inconsistent with state ADU law, so the city has amended it. Ask the city which version applies to your lot.

Is a room with no kitchen an ADU?

Not under the city’s hearing records. Accessory habitable quarters are described as not being a separate unit and as having no kitchen facilities. Adding a kitchen or a separate entrance can change how the city treats the space.

How an ADU or garage conversion affects selling a house in West Covina

A permitted ADU can be a selling point. An unpermitted one is a problem lenders and inspectors notice. In California, sellers generally must disclose known unpermitted work. On a traditional listing you can try to permit the unit, remove it, price it in, or offer a credit.

How to sell a West Covina house with an unpermitted ADU

1. Ask the city what is permitted at the address.
2. Gather what you have: plans, receipts, inspection cards.
3. Compare options: legalize, remove, or sell as-is.
4. Disclose honestly. A cash offer does not change disclosure duties but removes repair steps.

West Covina’s ADU ordinance timeline

The City of West Covina’s Planning Division says that on April 20, 2021, the City Council passed Ordinance No. 2480 to update its ADU ordinance to be consistent with state law.

The same city page says the city has 30 days to review a project from the initial official submittal, and that at 30 days the applicant receives either an incomplete (correction) letter or an approval letter.

A later round followed: the City Council considered Zone Change No. 22-02, an ADU ordinance (Ordinance No. 2500), at a public hearing on June 21, 2022, with the ordinance taking effect 30 days after adoption.

That agenda item also describes a 1,000-square-foot maximum for each ADU proposed within an existing multifamily residential use, and notes that setbacks are not required in certain instances described in Government Code section 65852.2 when an existing structure is converted to an ADU.

These records are older than today’s state statute numbers, which were renumbered in 2024, so check the city’s current ordinance text.

What state law sets as the floor for ADUs in West Covina

Whatever the city’s ordinance says, California law sets minimums that cities must follow. The Department of Housing and Community Development’s March 2026 ADU Handbook summarizes them, and the points below matter most for homeowners deciding whether a unit on their property can be permitted:

• Approval timeline: local agencies must act on a complete ADU application within 60 days.
• Size: a local agency must allow at least 800 square feet; a junior ADU is no more than 500 square feet of interior space.
• Setbacks: no more than 4 feet from the side and rear lot lines can be required for an attached or detached ADU.
• Height: 16 feet for a detached ADU, 18 feet within a half mile of a major transit stop or high-quality transit corridor (plus 2 feet for roof pitch that matches the main home), and 25 feet or the zone’s limit for an attached ADU, whichever is lower.
• Impact fees: an ADU of 750 square feet or less, or a JADU of 500 square feet or less, is exempt from impact fees charged by local agencies, special districts and water corporations.
• Parking: no more than one space per unit or bedroom, whichever is less, and the space can be tandem on a driveway. No parking can be required within half a mile walking distance of public transit, when the ADU is inside the existing home or an accessory structure, or when a car share vehicle is within one block. Replacement parking is not required when a garage is converted or demolished.
• Owner occupancy: not required for an ADU. For a JADU, owner occupancy applies if it shares sanitation facilities with the main home.
• Rentals: rental terms must be longer than 30 days.
• Separate sale: an ADU generally cannot be sold separately from the main home unless a local ordinance allows condominium conveyance or a narrow nonprofit exception applies.
• HOAs: covenants that effectively prohibit or unreasonably restrict an ADU or JADU on lots zoned for single-family use are void under the Civil Code.

On a lot with one single-family home, the handbook describes one ADU created from existing space, one JADU, and one newly built detached ADU. Multifamily lots have separate rules for conversions of non-livable space and for detached units.

How to start an ADU project in West Covina

1. Check zoning and what already exists. The city’s records say ADUs are allowed in areas zoned for multifamily and single-family residential use, subject to a building permit.
2. Read the city’s ADU handouts and guidelines. The Planning Division posts an ADU page and a Handouts and Guidelines page that includes ADU resources and application forms.
3. Submit and watch for the 30-day response. The city page describes a correction or approval letter at 30 days. Respond to corrections quickly, since the clock restarts the review process.
4. Plan utilities. City records say ADUs and junior ADUs must be connected to public utilities or their equivalent, including water and electric.
5. Schedule inspections through final. A unit that was never finaled looks like unpermitted work to a buyer.

Selling a West Covina house that has an ADU or converted garage

A permitted ADU can add value, but a buyer’s lender and appraiser will want proof that it was permitted and finaled. If you inherited the property, or bought it with a converted garage or backyard unit, ask the city what is on file before you list.

Under California Civil Code section 1102.1, an as-is sale does not waive delivery of the transfer disclosure statement, and your duty to disclose material facts stays in place, so a known unpermitted unit is something to raise with your agent or escrow officer.

If a disclosure reaches the buyer after an offer, section 1102.3 gives the buyer three days to cancel after in-person delivery or five days after mailing or agreed electronic delivery.

The usual choices are to legalize the unit, remove it, price the home accordingly, or sell to a cash buyer who takes it as it stands.

Why you should confirm West Covina’s current rules

The city’s ADU ordinance was revised more than once as state law changed, and some of the public records we reviewed date from 2019 through 2022. The state also renumbered its ADU statutes in 2024. Before relying on any summary, including this one, ask the Planning Division which ordinance applies to your lot and whether any recent change affects your plans.
