You’re considering a Chino Hills home, and a nearby site’s zoning raises questions about what could be built there. Housing Priority zoning sets housing density, height, design, and approval rules across four districts. It does not establish that a project is planned or approved.
This is general information, not legal or tax advice.
The first step is to identify the parcel’s actual district. Then you can read the applicable development standards and understand which approval process a project would follow.
What does Housing Priority zoning mean?
Housing Priority zoning implements the goals and policies of the City of Chino Hills General Plan Housing Element by facilitating housing development at specified densities.
Chapter 16.15 of the Chino Hills Municipal Code establishes four districts: Medium Density Housing (MDH), Urban High Density Housing (UHDH), Very High Density Housing (VHDH), and Mixed Use Housing (MUH). The chapter was adopted by Ordinance No. 418 on June 24, 2025.
Each district has its own development standards. The district name alone doesn’t tell you the full height limit, required setback, or approval process. Those details matter when you’re reading about a site near a home you’re considering.
What do MDH and UHDH allow?
MDH allows nine to twelve and one-half dwelling units per acre, while UHDH allows 30 to 93 dwelling units per acre.
MDH uses are the same as those in the RM-1 zone. Its maximum building height is 42 feet, and its front yard setback is 25 feet.
UHDH uses are the same as those in RM-2 and RM-3. Its minimum project area is four acres. The maximum height is 70 feet to the roofline and 80 feet to architectural features.
UHDH also lists five-foot setbacks for Boys Republic Drive and City Center Drive. Parking areas must sit behind the building when viewed from Shoppes Drive and Civic Center Drive. These street references describe development standards; they do not identify every parcel in the district.
What do VHDH and MUH allow?
VHDH allows 20 to 30 dwelling units per acre, while MUH lists a density of 30 to 47 dwelling units per acre with a minimum of 20.
VHDH has a minimum project area of 20,000 square feet. Its height limit depends on adjacent zoning: 42 feet next to residential zones, or 60 feet with a maximum of five stories next to nonresidential zones. Listed setbacks are 20 feet along Eucalyptus Avenue and 25 feet along both Peyton Drive and Country Club Drive.
MUH applies to Housing Element sites within commercial centers. It has a minimum project area of one acre and a maximum height of 80 feet. Listed setbacks are 10 feet along Shoppes Drive, five feet along Boys Republic Drive, and 20 feet along both State Route 71 and Chino Hills Parkway.
Which design standards apply?
All residential design in these districts follows CHMC Appendix F, Objective Design Standards.
Each district also makes minimum building separations in the Fire Hazard Overlay District subject to Chapter 16.22.030.B and approval by Chino Valley Fire District and the Director. That is a specific requirement to check when it applies to a site.
Keep these zoning questions separate from other property documents. If your purchase also involves association paperwork, the California HOA disclosure guide is a separate reference. A district’s design standards do not answer every question you have about the home itself.
Who reviews a project?
Chapter 16.15 provides two approval tracks: a discretionary Site Plan approval reviewed by the Planning Commission and a qualifying Housing Plan Approval decided by the City Manager.
Section 16.15.050(A) requires Site Plan approval for projects involving new buildings or the remodeling covered by that section. It identifies this as a Discretionary Permit subject to Planning Commission review and approval under Chapter 16.76.
The Housing Plan Approval route applies when at least two-thirds of the overall development’s square footage is designated for residential use and at least one fifth of residential units will be affordable to lower income households, subject to Government Code Section 65583.2. This is a Non-Discretionary Permit. Design and objective standards still apply.
When can you review materials and comment?
For Housing Plan Approval, application materials become available for public review once the application is complete, and the comment window follows notice of the Preliminary Decision.
The application must include a map of existing land uses on adjacent properties within a 600-foot radius of the site. Once complete, the Director must have all application materials posted on the city’s website and made available for public review.
The deadlines depend on project size:
- For 150 or fewer units, the Director issues a Preliminary Decision within 15 days of application completeness. Written public comments to the City Manager are allowed within 15 days after notice.
- For more than 150 units, those periods are each 30 days.
The City Manager issues a written Final Decision within 15 or 30 days after notice of the Preliminary Decision, using the same unit-count division. Notice follows Section 16.58.040.
What happens after Housing Plan Approval?
A Housing Plan Approval runs with the land and continues to be valid when ownership changes.
An unused approval expires within the time specified, or within three years of its effective date if no time is specified. The Director may extend it up to two years when a request is filed before expiration.
Section 16.15.060 also limits disapproval or required lower density to written findings of a specific adverse impact on public health or safety that cannot feasibly be mitigated. The code states that there is no administrative appeal of the decision and that an aggrieved party may seek judicial review.
How do you check a particular parcel?
Check the city’s zoning map and ask the Community Development Department which district the parcel is in.
Also check the current text in the city’s municipal code, especially Chapter 16.15 and its referenced sections. Street names in setback provisions are not a parcel list.
For the home purchase itself, keep the seller disclosure guide and the guide to unpermitted work disclosures alongside your zoning questions. They address separate parts of your document review.
J. loved the privacy at a house we were looking at. She kept going back to the yard and saying how nice it was to have that open space nearby. Her dad barely said anything during the showing. Then, as we were leaving, he asked, “Have you checked what they can build over there?” J. looked at me, and we both knew that needed an answer before she got any more attached. That’s where Housing Priority zoning becomes a very personal question.
The short version
Housing Priority zoning defines development rules across four Chino Hills districts, with different density, height, setback, and project review requirements.
Confirm the parcel’s district first. If a Housing Plan Approval application is under review, check the posted materials, unit count, and Preliminary Decision notice so you know the written comment deadline.

Common questions
What are the four Housing Priority zoning districts?
They are Medium Density Housing (MDH), Urban High Density Housing (UHDH), Very High Density Housing (VHDH), and Mixed Use Housing (MUH).
Does a street named in Chapter 16.15 identify a district's parcels?
No. The named streets are setback and parking references. Check the city's zoning map and ask the Community Development Department which district a parcel is in.
Who decides a Housing Plan Approval?
The City Manager decides this Non-Discretionary Permit. The route requires at least two-thirds residential square footage and at least one fifth of residential units affordable to lower income households, subject to Government Code Section 65583.2.
How long is the public comment window?
Written comments to the City Manager are allowed within 15 days after notice of the Preliminary Decision for projects with 150 or fewer units, or within 30 days for projects with more than 150 units.
