California HOA Common Area Laws: Who Maintains What Under Civil Code §4775

Who fixes what: the question that starts most HOA fights

A balcony rots. A pipe bursts inside a wall. A patio fence blows down. The first question in every one of these calls is the same: is this the association's problem or the owner's? California answers with a default framework in the Davis-Stirling Act — but every answer starts with "unless your declaration says otherwise," which is why the CC&Rs, not this article, are the first thing to check.

This guide walks the statutory defaults: what counts as common area, what counts as exclusive use common area, who maintains versus who repairs and replaces, and the utility-restoration duties added by SB 900. For the money side of maintenance — reserves and special assessments — see the reserve funding guide and the Davis-Stirling special assessment guide.

The three zones of an HOA property

California law slices a common interest development into three zones:

• Separate interest — the unit or lot the owner holds title to.
• Common area — everything in the development that isn't a separate interest (Civ. Code §4095(a)): pools, private streets, building exteriors, landscaping.
• Exclusive use common area (EUCA) — common area that the declaration designates for the exclusive use of fewer than all owners and that is appurtenant to a separate interest (Civ. Code §4145(a)). Unless the declaration says otherwise, the statute itself makes a default list: shutters, awnings, window boxes, doorsteps, stoops, porches, balconies, patios, exterior doors, doorframes and hardware, and screens and windows designed to serve a single unit but located outside its boundaries (§4145(b)).

EUCA is the zone that generates the disputes, because it looks like the owner's property but is legally common area — the balcony problem in its purest form.

The default maintenance matrix (Civil Code §4775)

Unless the declaration provides otherwise:

• Common area — Maintains: Association; Repairs & replaces: Association
• Separate interest — Maintains: Owner; Repairs & replaces: Owner
• Exclusive use common area — Maintains: Owner; Repairs & replaces: Association

The EUCA row is the one to memorize: the owner maintains the exclusive use common area appurtenant to their unit, but the association repairs and replaces it (Civ. Code §4775(a)(3)–(4)). Day-to-day upkeep of the balcony — sweeping, sealing, keeping drains clear — defaults to the owner; rebuilding the rotted deck structure defaults to the association. The line between "maintain" and "repair" is exactly where arguments live, and where a declaration that speaks clearly saves everyone a lawyer.

Two more defaults worth knowing:

• Relocation costs fall on the owner. If an owner must temporarily relocate while the association performs maintenance it's responsible for, those costs are borne by the owner of the affected separate interest (§4775(c)).
• The declaration always wins. Every allocation above is a default. CC&Rs routinely shift balcony repair to owners or landscaping in EUCA yards to the association — read yours before quoting the statute at a neighbor.

SB 900: interrupted utilities are now the association's clock

Effective January 1, 2025, SB 900 amended §4775 to deal with a specific failure: utility outages that start in the common area. Unless the declaration provides otherwise (or a utility provider is responsible), the association is responsible for repairs and replacements necessary to restore interrupted gas, heat, water, or electrical service that begins in the common area — even if the problem extends into a separate interest or EUCA (§4775(a)(2)).

The statute adds teeth:

• The board must commence the repair process within 14 days of the service interruption (§4775(b)(1)).
• If reserves can't cover it, the association may obtain financing and levy an emergency assessment to repay the loan without a member vote — after adopting a resolution with written findings on the expense and the reserve shortfall (§4775(b)(2)).
• If the board can't muster a quorum within 14 days, the next duly noticed meeting proceeds with a reduced quorum for that vote, and directors may vote electronically, including by email, with the records kept as association records (§4775(b)(3)–(4)).

These duties pause in declared disaster or emergency conditions that materially affect the association's ability to perform (§4775(e)). For the full picture, see the SB 900 utility maintenance explainer.

Access, inspections, and the limits of control

Two adjacent rules round out the common-area picture:

• Access is near-absolute. An association may not deny a member or occupant physical access to their separate interest, whether by restricting passage through the common area or access to the unit itself, except by court order or binding arbitration outcome (Civ. Code §4510). Common-area privileges can be suspended through proper discipline; the path to the front door cannot.
• Elevated structures carry inspection duties. Balconies, decks, and walkways supported by wood face the SB 326 inspection regime — see the balcony inspection requirements guide.

Because the association's repair-and-replace duties for common area and EUCA are funded through reserves, a board that doesn't know the condition of its decks, roofs, and pipes is carrying liabilities it hasn't priced. That's the reserve study's job — statutorily required and covered in the reserve study requirements guide.

Write the answer down before the next failure

The most useful thing a self-managed board can do with this framework costs nothing: build a maintenance responsibility chart for your specific development — every asset class (roofs, fences, garage doors, balconies, patio covers, utility runs, landscaping zones), its classification, who maintains, who repairs and replaces, and the CC&R section that says so. Adopt it at an open meeting, publish it to owners, and attach it to escrow disclosure packets. It won't change what the declaration requires, but it converts every future "whose problem is this?" call from a research project into a lookup — and it surfaces the ambiguities (the "maintain" vs "repair" seams) while they're still hypothetical, when amending or clarifying is cheap and nobody's insurance adjuster is on the phone.

A board's who-fixes-what playbook

1. Pull the declaration first. Every §4775 rule is a default the CC&Rs can change. Build a one-page maintenance matrix for your development and publish it to owners.
2. Classify the asset — separate interest, common area, or EUCA (§4095, §4145) — before debating whose checkbook opens.
3. Apply the default split — owner maintains EUCA, association repairs and replaces it — only where the declaration is silent (§4775(a)).
4. Calendar the SB 900 duties: 14 days to commence utility-restoration repairs, written-findings resolution before emergency financing (§4775(b)).
5. Never use access as leverage in a maintenance dispute (§4510).
6. Fund the matrix — reserve study, reserve funding plan, and honest line items. Try the free reserve calculator, and run the California HOA compliance check to spot gaps.

Stop relitigating the balcony

Most maintenance fights are really classification fights — nobody wrote down which zone the asset is in until it broke. Propty's California HOA platform keeps your maintenance matrix, work orders, vendor records, and reserve plan in one place, mapped to your actual CC&R allocations — so a self-managed board answers "who fixes this?" in seconds, not in executive session.
