Costa-Hawkins and Vacancy Decontrol Underwriting in LA

What Costa-Hawkins Actually Does

Costa-Hawkins is a 1995 California state law with two distinct effects that matter for LA apartment financing. First, it exempts single-family homes and condos, and buildings built after February 1995, from local rent control ordinances statewide (though newer buildings may still fall under AB 1482 once they age past 15 years). Second, and more consequentially for value-add investing, it establishes vacancy decontrol: when a tenant in a rent-controlled unit voluntarily vacates, the landlord can reset that unit's rent to market for the next tenant.

That second provision is the entire foundation of the classic LA value-add apartment trade: buy a regulated building with below-market in-place rents, and as units turn over naturally (or through a legally executed renovation and re-lease program), reset each one to market. The rent-cap formula that governs a stabilized, non-turning unit barely matters to this thesis; the turnover rate does.

Underwriting the Turnover Schedule

A credible turnover schedule starts with the actual rent roll: how far below market is each unit, how long has the current tenant been in place, and what is a realistic, conservative estimate of annual turnover for this specific building and submarket. Lenders are skeptical of turnover assumptions that look more like a business plan than a data-driven forecast.

Sponsors who overstate turnover speed to inflate projected proceeds are the most common reason a bridge loan gets re-traded mid-process. The stronger approach documents historical turnover at the specific property (or comparable buildings under the same sponsor's management) and builds a phased projection from that baseline rather than an aspirational one.

Ellis Act withdrawals are a separate, distinct mechanism, not a form of vacancy decontrol: an owner can remove an entire building from the rental market with proper notice and relocation payments, but that is a withdrawal-and-often-redevelop strategy, not a unit-by-unit turnover plan, and it carries its own deed-restriction consequences if the site is later redeveloped.

Matching the Lender to the Plan

Bridge lenders are built for exactly this kind of business plan: a value-add acquisition with a defined capital improvement and turnover program, underwritten to a projected stabilized rent roll at takeout. The best-fit bridge lenders for this trade want to see a realistic timeline (often 24-36 months), a specific renovation budget per unit, and evidence the sponsor has executed a similar plan before.

Once turnover and renovation are substantially complete, the takeout is typically agency or bank debt sized to the new, largely market-rate rent roll. Structuring the acquisition loan with the eventual takeout already in mind, rather than treating bridge and permanent financing as two unrelated transactions, produces the smoothest execution and the best combined proceeds.
