Picture two Craftsman bungalows on the same block of Belmont Heights, both built before 1923, both inside the boundary lines the city drew in 2002. A buyer touring both assumes they come with the same rulebook. They don't. One qualifies for a property tax cut of 30 to 50 percent and needs city sign-off before repainting the porch railing. The other gets neither the tax break nor the paperwork, and its owner can swap in fiberglass or aluminum windows without anyone at City Hall blinking.
The difference has nothing to do with which side of Newport Avenue the house sits on. It comes down to a single word buried in a 2002 survey: contributing, or not.
The Boundary Everyone Talks About
The Belmont Heights Historic District was formally adopted by Long Beach City Council on May 7, 2002, and its edges are specific: 7th Street to the north, 4th Street to the south, Newport Avenue to the west, Roswell Avenue to the east, with a handful of properties fronting 4th and 7th also included. Most conversations about buying in this pocket of Belmont Heights stop there, as if crossing that line is the whole story. Step inside the boundary and you're in the historic district. Step outside it and you're just in Belmont Heights proper, free to renovate as you please.
That framing misses the part that actually matters once you're comparing two specific houses.
The Split Inside the Boundary
When the city surveyed the district to establish it, planners walked 304 properties and sorted them into two piles. Two hundred six were ranked "contributing," meaning they retain enough of their original 1905 to 1939 character to count toward the district's historic fabric. Of those, 125 were flagged as pristine and largely unaltered. The remaining 37 homes, about 13 percent of everything inside the boundary, were ranked "noncontributing." They're old enough and located in the right spot, but a prior remodel, a replaced facade, or new construction outside the 1905 to 1939 window disqualified them.
That 13 percent is easy to overlook until you realize what it changes. A contributing home and a non-contributing home can sit three doors apart, both wearing the same Craftsman silhouette from the street, and still answer to entirely different rules the moment an owner wants to touch the exterior.
Here's how that plays out in practice:
| Contributing structure | Non-contributing structure | |
|---|---|---|
| Exterior changes visible from the street | Requires a Certificate of Appropriateness before work begins, even without a building permit | Also requires city review, but substitute materials like fiberglass or aluminum windows and fiber cement siding are permitted on a case-by-case basis |
| Mills Act eligibility | Can apply for a property tax reduction, historically averaging 30 to 50 percent for new owners | Not eligible |
| Design standard | Must match period-appropriate materials, colors, and proportions per the district's design guidelines | Reviewed for compatibility, with more flexibility since the structure isn't defining the district's character |
What Contributing Status Actually Costs You, and Buys You
Own a contributing home and any exterior work, from a new roofline to a repainted trim board, needs a Certificate of Appropriateness from the city before you start. Small jobs, like additions under 250 square feet or a solar install, go through as a Minor COA. Anything bigger, like a second story or an addition over 250 square feet, goes to the Cultural Heritage Commission as a Major COA. City case filings for the district show what this looks like on the ground: a reroof on a rear structure on Loma Avenue and a 166 square foot rear addition on 6th Street both moved through the process as Minor COAs. Neither was a large project. Both needed a certificate first.
In exchange, a contributing owner can apply for a Mills Act contract, the state program Long Beach has run since 1993. The tax relief runs 30 to 50 percent for owners who recently purchased the property, structured as a 10 year term that renews annually so it's always rolling 10 years out. It transfers to a new owner if the home sells, which is exactly why a buyer should ask whether an existing contract is already in place before assuming they'd have to apply from scratch. The 2026 application window has closed, and the next one opens in January 2027, with two mandatory workshops before the city will consider an application.
A non-contributing owner inside the same boundary skips both the certificate headache on small jobs and the tax incentive entirely. Practically speaking, that owner has more room to modernize on their own timeline and less reason to fight for the Mills Act line item on their tax bill.
The contributing home is protected. The non-contributing home is unlocked.
The Cleaner Case Next Door: Eliot Lane
A one block detour helps show why this split gets murky in the main district but stays simple somewhere else. The Eliot Lane Historic District, designated in 2003, covers just 30 cottages on a single street, all built in 1923 by one builder, Boland & Smith. The push for designation came from resident Linda Becker Babiak, whose family had owned a Spanish eclectic home on the street since 1925.
Because every house on Eliot Lane went up in the same year from the same builder, there's little ambiguity about what counts as contributing. The main Belmont Heights district spans three decades of construction and dozens of owners' worth of remodels between 1905 and 2002, which is exactly the kind of variation that produces a 13 percent noncontributing rate. Uniform blocks don't generate this problem. Diverse ones do.
Why the Number You Saw Online Doesn't Match What You're Touring
If you've priced Belmont Heights by pulling up a portal's median, you've probably seen numbers that don't agree with each other. One tracker put the median home price at $1,175,000 as of July 2026. A month later, another showed a median list price of $799,000 for August 2026, a very different figure because it's measuring what's currently asked rather than what already closed.
Part of that gap is sold versus list price data measured a few weeks apart. But the bigger reason a single "Belmont Heights median" is a blunt instrument is the district itself. The polygon these trackers draw around the neighborhood blends contributing homes carrying design restrictions and potential Mills Act savings, non-contributing homes with more renovation freedom, and properties entirely outside either historic district with no restrictions at all. Those are three different cost structures wearing one zip code. A median that averages across all three tells you less than knowing which bucket your specific address falls into.
A Sequence Before You Write an Offer or List
- Confirm whether the address sits inside the Belmont Heights Historic District or the Eliot Lane Historic District boundary, not just the broader neighborhood.
- Ask the city's Historic Preservation Office whether the specific structure was surveyed as contributing or non-contributing.
- Request any existing Certificate of Appropriateness history for the property. Past filings show what kind of work has already cleared review, which tells you how the city has treated similar projects on that block.
- If buying a contributing home, ask whether it already carries a Mills Act contract. If it does, the tax benefit transfers to you at closing.
- If you're the one considering a Mills Act application after purchase, plan around the city's cycle. The 2026 window has closed and the next opens in January 2027, with mandatory workshops before submission.
- Before budgeting a remodel, check whether the project falls under Minor COA thresholds (under 250 square feet) or triggers a Major COA review by the Cultural Heritage Commission, since the timeline and cost differ.
The Community Layer Watching All This
None of this happens in a vacuum. The Belmont Heights Community Association runs an award winning quarterly newsletter distributed to more than 3,000 residents and actively recruits volunteers to support both historic districts. Recent coverage has followed a freshman at Wilson High, Nick Mulvehill, working through his Eagle Scout project to repair and protect the historic lampposts along Belmont Avenue, the kind of granular preservation work that keeps a district's character intact one fixture at a time. That level of attention is part of why a contributing designation carries real weight here beyond the paperwork. Neighbors notice.
FAQ
Can I find out if a specific house is contributing before I make an offer? Yes. Contact the city's Historic Preservation Office and ask about the property's status from the 2002 survey. This is worth doing before you write an offer, not after.
Does a Mills Act contract disappear if the house sells? No. The contract transfers to the new owner along with the property, which is one reason to ask about existing contracts on any contributing home you're considering.
If my home is non-contributing, can I still apply for historic designation later? Properties not currently classified as contributing would need to go through a separate landmark nomination process with the city, which is a different track from simply owning a home inside the district boundary.
