Rancho Del Rey Zoning: SPA Plans, Open Space and HOAs

How planning works in a master-planned Chula Vista community like Rancho Del Rey, the SPA plans and open-space district behind it, the HOA layer, and how Rudy can help start the conversation.

Updated October 2026 · Rudy Flores · Coldwell Banker West

In a master-planned community such as Rancho Del Rey, what you can do with a property is set in more than one place: the city’s zoning, the plan the neighborhood was approved under, and the homeowners association. Here is how the layers fit, and where Rudy’s permitting experience can help you start well.

Three layers to check

Chula Vista’s zoning and building rules. The city’s Development Services department handles planning applications and permits.
The community’s planning approvals. Rancho del Rey was approved in Sectional Planning Areas, known as SPAs, and the City of Chula Vista notes SPAs I, II and III in describing the open-space district that pays to maintain natural and landscaped open space across the community. That district was formed in 1989. Ask the city how the SPA plan for your address applies.
The homeowners association. Associations set design rules for exteriors, additions and sometimes ADUs. Get the CC&Rs and the design-review process before you plan.

ADUs in Chula Vista

Chula Vista publishes an accessory dwelling unit page for homeowners and has been building a program of city-approved standard plans for detached ADUs, which can shorten review. State law guarantees the right to at least one ADU of a minimum size, and an HOA’s rules may still affect design, so check both. The ADU return estimator helps you weigh cost against rent.

Backyard and garage units. The state tightened the ADU rules again for 2026: cities have 15 days to tell an applicant whether an ADU application is complete, with silence counting as complete (SB 543); junior ADUs can carry an owner-occupancy rule only if they share a bathroom with the house (AB 1154); and a city’s ADU ordinance is void unless it is filed with the state’s housing department on time and answered promptly (SB 9 of 2025).

Canyon edges and open space

Homes backing onto open space bring extra questions: property lines and easements, drainage, fire-hazard mapping, and who maintains the slope. The article on eight things to check on a canyon-edge home covers them, and any project on such a lot should be raised with the city early.

What California changed for 2026

Faster permits. If a jurisdiction cannot meet a 30-business-day post-entitlement review estimate, applicants can use private plan checkers (AB 253), and final inspections must be completed within 10 business days after the builder notifies the city that construction is finished (AB 1308).
Two homes on one lot. Under SB 9 (2021), many single-family lots can hold a duplex or be divided into two lots through a ministerial process, with limits. AB 1061 widens it in 2026 to projects inside historic districts, as long as the structures are not individually designated.

How Rudy can help start the conversation

Before real estate sales, Rudy worked 12 years as a real estate developer for the telecommunications carriers, shepherding sites through local approvals from Los Angeles to San Diego and beyond. That is why he is comfortable at a planning counter and comfortable telling you what he sees there.

If you are thinking about a project in Rancho Del Rey and Chula Vista, he can help you frame the question, find the right people at the city, and start the dialogue. Then he can help fold what you learn into your decision to buy, sell or hold. He is not an attorney, architect, engineer or contractor, and he does not promise that any application will be approved.

Common questions

Do I need HOA approval as well as a city permit?

Often yes. They are separate approvals with separate rules.

What is an SPA plan?

A Sectional Planning Area plan is a detailed plan for part of a master-planned community, approved by the city, that sets land uses and design standards for that area.

Where do I start?

With the city’s planning staff for the zoning and the SPA plan, and with your association for its design rules.
