Arcadia Wood Flooring has spent more than 20 years on wood-flooring in East Pasadena and the surrounding valley, and most of what we do here starts with a floor that is older than the people who own it. We refinish, repair and install solid and engineered hardwood, reset parquet, and rebuild stairs, with the same crew doing the assessment and the work.

The floors that come through our schedule here are rarely simple. Oak strip that has been sanded three or four times, fir boards that were carpeted over for decades, and midcentury parquet that has started to lift all need a different first step, and we decide that step on site before anyone quotes a price.

This page explains what makes floor work in this community different: the age of the houses, the county agency that governs building work, the rules that apply to rental houses, and how floor projects fit alongside seismic work under older raised foundations.

Wood Floors in Houses Built Before 1950

Half the Housing Stock Is Prewar or Wartime

Census figures from the 2024 American Community Survey five-year estimates show how old this community’s houses really are. Of 2,330 housing units, 622 were built in 1939 or earlier, which is 26.7 percent, and another 541 went up in the 1940s. Taken together, 49.9 percent of the homes here predate 1950.

That changes the conversation before a sander ever arrives. A floor from that era may be tongue and groove oak strip nailed to a board subfloor, or it may be fir that was never meant to be seen. Either way, it has usually been refinished more than once, and how much wood remains above the tongue decides what we can promise.

What Eighty-Year-Old Oak and Fir Tend to Show

Old floors carry their history in plain sight. We see gray boards near doorways where water sat, black water stains where moisture sat under rugs or planters, pet urine stains that went through the finish long ago, and worn-through finish down the middle of hallways. Squeaks, nail pops and hollow spots are common where the subfloor has dried and shrunk over time.

We probe each problem area before deciding between sanding, board replacement or a weave-in repair. A stain that has reached deep into the fibers will not sand out, and cutting in matching strip is usually better than sanding a floor thin chasing it. Where a board is too far gone, we source red oak or white oak that matches the width and grain.

Confirming the Build Year Before Any Sanding

With 80.6 percent of local housing built before 1980, we check the build year on every job before sanding is booked. Finish and paint layers in pre-1978 housing fall under the EPA Renovation, Repair and Painting Rule, so the containment, dust control and cleanup plan is set at the quote stage rather than improvised on day one.

That same check shapes how we sand. We use dust containment and dustless sanding equipment, work through an abrasive grit sequence matched to the wood, and keep the drum sander and edger passes controlled to avoid chatter marks, edger swirl and sand-through on floors that have little wear left to give.

A Pasadena Address on County Land

Who Governs Building Work Here

Mail here carries a Pasadena address and the 91107 ZIP, but East Pasadena is an unincorporated community in Los Angeles County, not part of the City of Pasadena. Building work answers to Los Angeles County Public Works, Building and Safety Division, under the County of Los Angeles Building Code in Title 26 of the County Code.

Permits for unincorporated areas are handled online through EPIC-LA, the county’s electronic permitting portal. When a floor project grows into subfloor replacement, joist work or anything structural, we point owners to the county rather than to a city counter, because an application sent to the wrong agency only costs time.

What the City of Pasadena’s Programs Do Not Reach

Owners who moved here from inside Pasadena city limits sometimes expect the same rules to follow them. They do not. The City of Pasadena’s rent control and its landmark-district program stop at the city boundary, and this community sits outside it, bordered by Michillinda Avenue on the east and California Boulevard on the south.

For floor work, that means decisions about refinishing a prewar oak floor, changing a stain color or replacing old strip with wide plank are made by the owner under county rules, not by a city preservation review. We still recommend keeping original wood where it can be saved, because it usually outlasts anything that replaces it.

Rental Houses Under County Tenant Rules

About 27.6 percent of households here rent, and 302 renter households live in detached houses. The county’s Rent Stabilization and Tenant Protections Ordinance applies in unincorporated areas, administered by the Department of Consumer and Business Affairs, with rental units registered in the Los Angeles County Rent Registry. Whether a particular house is covered is a question for that department.

What we can help a landlord with is the floor itself. Between tenants, we document condition with photos so normal wear and tear can be separated from damage that might support a security deposit deduction. A screen and recoat often freshens a rental floor in a day or two without the cost and downtime of a full sand.

Chapman Woods and the Older Detached-House Stock

A Neighborhood of Owner-Occupied Houses

Chapman Woods, named after Alfred Chapman, is where many of the community’s older detached houses sit. Across East Pasadena, 83.6 percent of housing units are one-unit detached homes and 72.4 percent of households own. Among owner households, 96.0 percent live in a detached house.

Those numbers show up in the kind of projects we are asked to plan. Owners here tend to stay, so they want a floor that will hold up for another twenty years, not a quick cosmetic pass. That usually means repairing the subfloor and fastening before refinishing, and choosing a finish system for long wear rather than the fastest turnaround.

Parquet and Strip From the 1950s

Another 405 local houses were built in the 1950s, and many of them came with oak strip or parquet. Where the wood allows it, we restore these floors in place: loose parquet tiles are reset, missing pieces are matched from salvage or new stock, and only then does sanding begin.

Lifting parquet raises a second question we answer before tiles come up. The adhesive underneath may be black mastic or cutback adhesive, and we identify what it is before deciding how to handle it. Scraping an unknown adhesive on a guess is not how we work on floors this age.

Stairs, Thresholds and Room-by-Room Scheduling

Older two-story houses often have stairs that were carpeted over or worn down at the nosing. We price stair work by the tread, riser and stair nosing, including landing treads and any retrofit treads, instead of folding it into a square-foot figure that hides what the stairs actually cost.

Before work begins, each household gets a written room-by-room schedule showing when rugs, furniture and people can return to each space. Cure time and the recoat window of the finish drive that schedule, and knowing it in advance matters for anyone living in the house during the project, including older relatives and children.

Seismic Retrofit and Floor Work Under Older Houses

Earthquake Brace + Bolt and ZIP 91107

The 2025 Earthquake Brace + Bolt list for Southern California includes ZIP 91107, listed under Pasadena, and the program states that eligibility is based on ZIP code. The program funds up to $3,000 toward retrofitting wood-framed pre-1980 homes with a raised foundation. Whether a specific house qualifies is decided by the program, not by us.

For owners weighing that retrofit, the timing relative to floor work is worth thinking through. Foundation bolting and cripple wall bracing happen in the crawl space below, and the vibration and access involved can disturb fragile finishes or loose boards above. We generally suggest scheduling the retrofit first and refinishing afterward.

Checking What Sits Below the Floor

A sagging floor, a sloping floor or a bouncy floor in an older house usually points to something under it. Before we sand, we look for undersized or damaged floor joists, a soft spot in the subfloor, termite frass or kick-out holes from drywood termites, and signs of past water in the crawl space.

When structural repair such as a sister joist is needed, that is building work under county rules, and it comes before any refinishing. If a Wood Destroying Pests and Organisms Inspection Report has been done for a sale, we read it before quoting, because tent fumigation or pest repairs can change what the floor needs next.

Moisture, Humidity and Finish Choice

The National Weather Service places East Pasadena in forecast zone CAZ548, Los Angeles County San Gabriel Valley. Indoor relative humidity still shifts through the year, and wood follows it, so we take moisture meter readings, write them down, and compare them with the wood’s expected equilibrium moisture content before calling a gap a defect.

Seasonal gapping, cupping or crowning often settles once conditions even out, and replacing boards too early can create buckling later. For the finish, we choose from products legal to apply under South Coast AQMD Rule 1113, whose wood coatings VOC limit is 275 grams per liter, including waterborne polyurethane and hardwax oil in the sheen level each owner prefers.
