Board authority to adopt rules

Delegated, not automatic

A board does not have built in authority to regulate something just because it is the board. Its power exists only where a specific document or law hands it over. Restatement commentary on servitude law, discussed in a Nevada Supreme Court decision, puts it directly: an association can make rules about property it owns and controls in common, but has no built in power to regulate what an owner does on their own lot.

"[A]n association enjoys an implied power to make rules in furtherance of its power over the common property" but "has no inherent power to regulate use of the individually owned properties in the community."

Before adopting any rule, a board should be able to name the exact document, section, or statute that gives it authority over that subject. "We've always handled it this way" is not a source of authority.

Common property versus an owner's own lot

The default authority reaches common property: the clubhouse, the pool, shared roads, common landscaping. It does not automatically reach what an owner does on their own lot. Restricting what an owner builds, plants, or paints on individually owned property needs a specific grant, almost always language written into the declaration itself, and in some cases a state statute.

"Except to the extent provided by statute or authorized by the declaration, a common interest community may not impose restrictions on the structures or landscaping that may be placed on individually owned property, or on the design, materials, colors, or plants that may be used."

A board that wants to require a particular fence style, or ban a paint color, needs to find that authority in the declaration. If it isn't there, the board cannot create it by adopting a rule. See Covenant vs rule for how the two differ.

Where to look for the grant

Practitioners describe three layers of governing documents. The declaration (CC&Rs) creates restrictions that run with the land and bind every owner. The bylaws govern how the association itself operates, including whether and how the board can adopt rules. Rules and regulations are what the board adopts under whatever authority those documents, or a state statute, hand it, covering day to day matters the declaration and bylaws don't already address.

Rules sit near the bottom of that stack. They are easier to change than the declaration, and courts review them differently, see Reasonableness. That is the tradeoff: easier to adopt, weaker legal footing.

Why the source of authority matters later

This isn't just paperwork. If a rule is ever challenged, whether the board had authority to adopt it at all is often the first question, before anyone gets to whether the rule itself was reasonable. A rule adopted within clear authority still has to pass a reasonableness test that the declaration doesn't face. A rule adopted with no underlying authority can be struck down before reasonableness is even considered.

Which documents grant rulemaking power, and how explicit that grant must be, varies by state and by your own declaration and bylaws. See What makes a rule enforceable? for the full test.
