The neighborhood
Cimmaron Oaks: condos, townhomes and their HOAs
Cimmaron Oaks, also spelled Cimarron Oaks, is a community of condos and townhomes in north Diamond Bar, along streets like Sylvan Glen Road, Cleghorn Drive, High Knob Road and Monument Canyon Drive, and on Golden Springs Drive. Carlton J. Peterson Park, with the city's 10,000-square-foot skate park, is right on Sylvan Glen Road, and Diamond Point Elementary is nearby.
The units were built in phases from the late 1970s through the late 1980s, mostly two- and three-bedroom plans, many of them two-story townhomes and some with living space over the garages. Each phase has its own association, and what the dues cover varies: one association includes trash, water and roof coverage; another covers fire insurance and exterior maintenance.
In short
Ceiling repair in Cimmaron Oaks means working out which unit or common area the water came from, which of the several HOAs is involved and what it covers, then drying and rebuilding your ceiling once that's settled.
What's common
Common ceiling leaks in Cimmaron Oaks units
Roof leaks over a whole building
A single roof covers several units, so one failed flashing can show up in more than one ceiling. Where the HOA covers the roof, report it to them first.

Original supply lines
Units that haven't been re-piped have supply lines that are 35 to 45 years old. Pinholes and fittings inside shared walls and ceilings are hard to spot until they stain.

Living space above parking
Where living space sits over garages, a leak can show in the garage ceiling first. Garage ceilings attached to living space are also often fire-rated, so they're rebuilt with the right drywall.

Step by step
How a Cimmaron Oaks ceiling repair usually goes
- Stop and protect. Bucket down, breaker off for any wet light, and if the water is from above, knock on the neighbor's door.
- Notify the right HOA in writing, with photos and the time you noticed it.
- Find the source. It's traced with moisture readings and, where needed, a small inspection opening, and the findings documented.
- Settle responsibility. The HOA, the neighbor and the insurers work from the contractor's report and the CC&Rs. The condo leak guide explains the default California rules.
- Dry and rebuild. Wet materials out, the cavity dried to readings, new drywall and the texture matched.
Common questions
Cimmaron Oaks questions
HOAs, stacked units and shared roofs.
My Cimmaron Oaks HOA covers the roof. Does it pay for my ceiling too?
Not necessarily. Some Cimmaron Oaks associations include roof coverage in the dues, which usually means the association handles the roof itself. Whether it also pays for the drywall, paint and belongings inside your unit depends on your CC&Rs and the association's insurance. Ask the manager for the maintenance chart or the relevant CC&R section.
Why are there several Cimmaron Oaks HOAs?
The community was built in phases and tracts, so there are separate associations (for example Cimmaron Oaks I and Cimarron Oaks VII and VIII), each with its own documents, dues and rules. Make sure you're talking to the one that covers your building.
Water is dripping from my ceiling and my townhome is over the garages. Where's it coming from?
In stacked townhomes with living space over garages, a ceiling leak usually comes from the unit or roof above you, not below. Check whether your upstairs neighbor has a bathroom, laundry or water heater over the wet spot, and look for staining in the garage ceiling below too.
How old are the Cimmaron Oaks condos and townhomes?
Most units were built between the late 1970s and the late 1980s. Some owners have had units re-piped; others still have original plumbing, which is now 35 to 45 years old.
Is it Cimmaron or Cimarron Oaks?
You'll see both spellings on listings and HOA documents. They refer to the same community off Golden Springs Drive near Peterson Park.
Can the contractor coordinate with the HOA manager and my neighbor?
Yes. Ceiling contractors commonly share photos, moisture readings and a written scope so the association, your neighbor and any insurers are looking at the same facts.
