Big Sky is a newer master-planned community, which makes one diligence item stand out: the possibility of Mello-Roos on top of HOA dues. Here’s what to verify before you buy.

Direct AnswerBig Sky uses a modern community-association structure covering common areas, architectural review, and reserves, with rules in the CC&Rs that can vary by tract. Because it is newer construction, some homes may also carry Mello-Roos — a special tax on the property tax bill, separate from HOA dues. Verify both the HOA dues (in the disclosure package) and any Mello-Roos (on the tax bill) to understand your true monthly cost.

Big Sky’s HOA: newer construction, modern structure

Big Sky is a newer master-planned community, so its HOA reflects modern planned-development design: a community association that maintains common areas and slopes, enforces architectural and use standards through recorded CC&Rs, and funds reserves for future repairs. Homes were delivered across named sub-tracts, and the governing association and exact rules can vary by tract.

Because the community is comparatively new, its reserve study and budget tend to be more straightforward than those of older communities — but that’s no substitute for actually reading them.

The Mello-Roos question — check the tax bill, not just the HOA

The most important thing that distinguishes diligence on a newer community like Big Sky is the possibility of Mello-Roos. A Mello-Roos community facilities district is a special tax used to fund infrastructure (roads, schools, utilities) in newer developments, and it is completely separate from HOA dues.

  • Mello-Roos appears on the property tax bill, not in the HOA budget.
  • It typically has a defined term, after which it expires — confirm the remaining years.
  • The annual amount can be significant and affects your true monthly cost of ownership.
  • Two homes in the same community can differ if they fall in different districts.

Always verify whether a specific Big Sky home carries Mello-Roos, the annual amount, and the years remaining — review the property tax bill and the title/disclosure documents. Don’t assume from the HOA dues alone.

What the HOA typically covers and controls

  • Common-area and slope landscaping and any community open-space maintenance.
  • Architectural review for exterior changes, paint, solar, landscaping, and additions.
  • Use restrictions in the CC&Rs — parking, rentals, pets, and similar.
  • Reserve funding for future repairs of association components.

If you plan to remodel, add solar, or build an ADU, confirm the architectural process up front. California law limits an HOA’s ability to prohibit solar and, in many cases, ADUs, but associations can still set reasonable documented standards.

How to verify dues and Mello-Roos

  1. Identify the exact tract and confirm the governing association.
  2. Request the HOA disclosure package — current dues, CC&Rs, budget, reserve study.
  3. Pull the property tax bill and check for Mello-Roos: amount and remaining term.
  4. Confirm any pending assessments or rule changes with the management company.
  5. Factor HOA dues and Mello-Roos together into your true monthly cost.

How to read CC&Rs and reserves: The CC&Rs are the recorded rules that bind every owner; the budget shows where dues go; the reserve study shows whether the association is saving enough for future big-ticket repairs. A poorly funded reserve is the classic warning sign for a future special assessment. You receive these in the seller’s HOA disclosure package — read them during your contingency period before removing contingencies.

Frequently Asked Questions

Does Big Sky in Simi Valley have Mello-Roos?

Some Big Sky homes may fall within a Mello-Roos community facilities district, which adds a special tax to the property tax bill, separate from and in addition to HOA dues. Whether a specific home has it — and the amount and remaining term — must be verified on that home's tax bill and disclosure documents.

Is Mello-Roos the same as HOA dues?

No. HOA dues are paid to the homeowners association for common-area maintenance and reserves and appear in the HOA budget. Mello-Roos is a special tax that funds public infrastructure, appears on the property tax bill, and usually expires after a set term. A home can have one, both, or neither.

What does the Big Sky HOA cover?

Typically common-area and slope landscaping, architectural review, enforcement of the CC&Rs, and reserve funding for future repairs. Exact coverage and rules can vary by tract, so read the specific association's budget and CC&Rs.

How do I find Big Sky's current HOA fees?

Request the HOA disclosure package for the specific home — it contains current dues, the budget, the reserve study, and the CC&Rs. Pair that with the property tax bill to check for Mello-Roos so you understand the full monthly cost.
