North Richland Hills Wood Flooring has been installing and refinishing wood flooring in Addison for more than twenty years, and the first question we ask on a job here is rarely about species or finish. It is about how the floor sits inside the rest of the scope. The town’s adopted code measures remodel and reconstruction cost against a figure a third party publishes, which makes a floor quoted on its own and a floor quoted as one line of a gut remodel two different conversations.
So we write the scope down before we write a price. The flooring work is itemized on its own, dated, and kept legible next to whatever else is happening in the building, so nobody has to guess later which part of a remodel budget belonged to the floor.
None of that changes how the wood goes down. It changes when the wood goes down, what order the trades run in, and how much of the job we are willing to put on a calendar before the whole scope has been assembled and looked at.
What the Dallas Central Appraisal District figure has to do with a floor
Dallas Central Appraisal District is the appraisal district for Dallas County, and it publishes an assessed value for the structure on a property. The town’s adopted code uses that published figure as the denominator in a cost test on remodel and reconstruction work. We are naming a mechanism here, not a number: we do not quote assessed values, and we do not tell an owner where a job lands against one.
What we can control is our own figure. Tear-out, subfloor preparation, material, sanding and finish are broken out separately on our estimate, so the flooring line stands by itself and can be handed to a designer or a general contractor without unpicking it first.
The ordinance behind the test
Addison adopted the International Residential Code, 2024 Edition, by Ordinance No. O24-013, passed April 23, 2024 and effective June 1, 2024. That ordinance repealed Ordinance No. 020-15 and replaced Chapter 18, Article IV of the Addison Code of Ordinances.
Adopted alongside it were Appendices BE (Radon Control Methods), CD (Piping Standards for Various Applications) and BF (Patio Covers). The edition matters to us because every local answer rides on top of it. The 2024 International Residential Code is the base text, and the town’s own amendment items are where the specifics live.
The town’s fifty percent cost test
The amendment at Section R309 and R313 requires an approved automatic fire sprinkler system in any existing building of any size, area or occupancy remodeled or reconstructed after the ordinance’s effective date where the costs of the residential or commercial remodel or reconstruction exceed 50 percent of the dollar value of the structure as most recently assessed by the Dallas Central Appraisal District. The same amendment reaches reconstruction resulting from structural damage that involves more than 50 percent of the structure’s square footage.
Whether a given project meets either test is for the owner, the designer and Town of Addison Development Services, Building Inspections to settle. We do not design sprinkler systems and we do not give fire protection advice.
Our job is narrower and earlier. Hand over a clean floor scope and a clean floor number while the rest of the project is still being assembled, and the people who do have to answer that question have something real to work from before demolition starts.

Where a floor sits inside a remodel budget
A floor replacement priced on its own is usually a modest line. The cost test reads the remodel or the reconstruction, not the flooring invoice, so the floor’s relationship to it depends entirely on what else is being done to the building at the same time.
That is the practical reason we price repair, refinish and replacement in that order, and name the cheaper option first whenever it is the right one. When a scope is being measured against a threshold, the smallest correct answer is worth the time it takes to find.
Repair and refinish before replacement
Board replacement, a weave-in, lacing and a dutchman patch will often fix damage that looked at first like a whole room. Matching the run direction and the board widths is most of the work, and a repair that laces into the existing field disappears in a way a new threshold at the doorway never does.
A screen-and-recoat renews a finish that is worn but not cut through, at a fraction of a full sand through the 36-50-80 grit sequence with a drum sander, edger and buffer. Where the wood has gone gray or the boards show overwood at the seams, the full sand is the honest answer and we say so.
On engineered flooring we measure the wear layer before quoting a refinish at all. Under about three millimeters there is not enough wood over the plywood core to sand safely, so a six millimeter wear layer and a two millimeter wear layer get opposite recommendations, and a sand-through to the core is not something anyone repairs afterward.
Reconstruction after damage
The square footage leg of that test is the one that turns up after water. We document water damage room by room for the claim file, with photographs, moisture meter readings and a line of sight map, so the extent of the affected area is recorded rather than argued about weeks later.
That same record tells us what the floor itself needs. Cupping, crowning, buckling and adhesive bond failure read differently once it is clear how far the water traveled, how long it sat, and whether the boards have come back toward their equilibrium moisture content on their own.
Additions for livable area
One carve-out in the town’s amendment set is worth knowing about. Existing unsprinklered single-family detached dwellings that are added to for the purpose of increasing livable area are not required to contain an automatic fire sprinkler system.
Where a floor runs out of an existing room into new livable area, our attention goes to the joint. Subfloor heights get matched before any wood arrives, the expansion gap is sized at the perimeter rather than at the seam, and the material is acclimated inside the house, in the room it is going into, never in the garage or on the truck.
Not less compliant than before: what the town amended
The town amended Section R102.6.1 so that additions, alterations, repairs and relocations shall not cause an existing structure to become less compliant with the code than it was before the work. For flooring, that is mostly a question of height. Every bit of thickness a floor assembly gains has to be taken out of something else, and the something else is usually a stair or a door.
Stairs, thresholds and transitions
A build-up at the top of a stair run changes the top riser, and wrapping a tread with a new nosing changes it again. We measure riser heights, tread depth and door clearance before tear-out and again once the assembly is set, then hand those numbers over instead of discovering the change at the final walk.
Transitions get the same treatment. A reducer, a T-mold or a threshold should land at a height somebody chose on purpose, and transition track anchoring into a slab is a decision made before the first hole, not during.
What goes under the floor
Self-leveling underlayment, a vapor retarder, plywood sleepers and a floating plywood subfloor system each carry their own thickness. We pick the assembly around the finished height the doors, the stairs and the adjoining rooms will actually accept, rather than picking it first and negotiating with the stairs afterward.
Flatness gets settled in the same pass. An assembly bridging hollow spots will telegraph them into the finished floor, and on a glue-down engineered installation it is where bond line failure starts.
Older houses and lead-safe work
The town’s housing record counts 87.8% of units built 1980 or later. We still check the build year on every house, because the federal lead rule turns on pre-1978 housing and a town-wide count says nothing about the house we are standing in.
Where a house does predate 1978, we use lead-safe work practices: containment, dedicated cleanup and cleaning verification, following the EPA RRP lead-safe rule at 40 CFR 745 Subpart E. Sanding a floor is exactly the activity that rule was written around, and it is nowhere near the six square foot minor repair threshold.
Dustless containment goes up on every sanding job regardless of the year on the house. We set it up and walk you through it before the first machine runs, because the time to disagree about where the plastic goes is before the drum sander is loaded in.
Hard-surface floors in buildings that were never houses
The sprinkler amendment names any existing building of any size, area or occupancy, so a wood floor going into a tenant space is read against the same cost test as a floor inside a house. Addison’s daytime population was estimated at over 120,000 as of 2010 against a 2020 census residential population of 16,661, and the town holds close to 200 restaurants. Plenty of the hard-surface floor we are asked to look at here sits in a building nobody has ever lived in.
The slab decides the method
Before anything is fastened into a slab we establish whether it is a post-tension slab or a conventionally reinforced slab, because a tendon is not something to find with a nailer. That answer picks the method: nail-down with cleats or staples over sleepers, glue-down engineered, or a floating floor, chosen from what the slab actually is rather than from habit.
Moisture comes before the calendar. We test to a recorded number, using the in-situ relative humidity test described by ASTM F2170 or a calcium chloride test for moisture vapor emission rate, and the installation date is set after that number exists, not after the wood is already on site.
Burnished concrete, old adhesive and a slab that is flat in one direction and not the other all change the preparation line rather than the finish line. We would rather quote the preparation honestly than discover it on the morning of a tear-out.
Species and traffic
Traffic in a workplace is not house traffic, and species choice carries more of that load than finish choice does. Red oak, maple, white oak at 1360 Janka and hickory at 1820 Janka all behave differently under chair casters and carts, so the Janka hardness rating is the first number we put in front of a tenant.
How the wood is presented matters too. A wire-brushed or hand-scraped surface hides the traffic a smooth site-finished floor shows, and a herringbone or chevron layout in a public room costs more in labor and waste than a straight run of the same material.
Sequencing and the schedule you get
We sequence flooring after foundation repair and plumbing rather than ahead of them, so the floor is not paying for somebody else’s delay. One crew runs the job from tear-out to final coat and the sanding is never subcontracted out, which is how the sanding sealer and the finish coats stay on one standard.
Before the first coat goes down you get a written cure and occupancy schedule: cure time versus dry time for waterborne polyurethane, oil-modified polyurethane or hardwax oil, and when furniture and pets come back into the room. Fastener spacing schedule, crown width and expansion gap follow the NWFA installation guidelines, and the plan is shown to you rather than explained afterward.
On the code side we stay in our lane. We name Town of Addison Development Services, Building Inspections as the authority, we point at the amended Section R105.2 exemption list, which reads ‘Painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work’ and does not name wood flooring, and we let the town answer what the town answers.
