The commercial stock is small enough to name. In 2015 the County found a single store in Grayson, a small convenience market with gas pumps and a laundromat, with the nearest full-service groceries about two miles away on Highway 33 in Westley. LAFCO describes the land inside the district as residential, commercial and industrial, and the County's own housing work calls the community almost entirely single-family. Commercial construction here is one building at a time, not a parade of suites.
The largest planned alteration in the community is a public one, and it shows what this work involves. The County's capital plan sets out an evaluation of the systems in the 3,165 square foot United Community Center building at Laird and Mary Streets, replacement of an HVAC system at the end of its useful life, and bringing the walkways and parking into code compliance. That last item is the path of travel itself, which CBC 11B-202.4 carries to any altered area, as the State Architect's access manual sets out.
How much of the route outside the door is done in one phase is capped by cost. Exception 8 limits path-of-travel compliance to 20 percent of the adjusted construction cost at or below the valuation threshold, republished at $209,208 for 2026, and sets the order the money goes in: the entrance, the accessible route to the altered area, then a restroom. Around 40 percent of housing units in Grayson have no sidewalk in front of them, so an accessible route is often new work.
Grayson is unincorporated and sits on the edge of a mapped floodplain, so two County reviews run together. Permits come from the Building Permits Division at 1010 10th Street in Modesto, and the community services district has no land use authority. The County borders the 100-year floodplain of the San Joaquin River here: a flood development permit is usually obtained with the building permit, the zone determination is typically made when the application is received, and repairs are reviewed as a substantial improvement once their cost exceeds half the value of the original structure.
The town's oldest buildings go back further than any presumption about asbestos. Grayson was started in 1849 and was one of the county's most active river ports for grain, wool and produce by the 1880s. Cal/OSHA section 1529 presumes thermal system insulation and surfacing material in a building constructed no later than 1980 to contain asbestos unless testing shows otherwise, and puts the determination of what is present, where and in what quantity on the building owner before work begins. Lead in older paint is covered by section 1532.1.
The community services district, formed in January 1969, provides street lighting and sewer to 240 residential customers and one commercial customer, from a plant designed for 100,000 gallons a day that the district says is at capacity. That is the whole non-residential connection count.
Fourteen road miles separate the Modesto base from Grayson, reached by West Grayson Road off Highway 33 or across the bridge from the east. The building is measured as found, and one file carries the job.
The request records the building, who occupies it and what the alteration is meant to achieve, and the contractor assigned to it walks the site. Site visit scheduled at a time that suits you. Start date set in the written estimate. Access matters here, since driveways in this part of the county are often long, narrow or unmarked.
The building is measured as it stands. The entrance, the route from the arrival point, the restroom serving the space and the signs are listed in the code's own order, and the survey status for asbestos and lead in an older structure is settled before anything is opened up.
The County's Building Permits Division in Modesto issues the permit, since the district holds no land use authority, and it determines the flood zone when the application arrives.
Discipline drawings, energy calculations and the access declaration are lodged, with a flood development permit alongside where the mapping calls for one.
The estimate is written line by line, with the path-of-travel items priced apart from the rest because Exception 8 keeps them out of the adjusted construction cost. Milestones follow the inspections the job must pass, and hidden conditions are flagged as subject to change on findings.
Demolition leaves for a permitted facility on the 65 percent diversion route, and nothing is covered before inspection.
The final inspection closes the permit, and the handover file gathers the permit card, the inspection record, the diversion tickets and photographs of the completed work.
Grayson covers about 100 acres, so its eight named places hold everything a build-out here is likely to involve.
A five-acre community centre and park at Laird and Mary Streets with a 3,165 square foot building, a bus stop alongside, and a County project to evaluate its systems, replace an HVAC unit and bring the walkways and parking into code compliance.
Well 274 at 8820 Charles was drilled in 1967 and is now inactive; Well 69 replaced it at the south-east corner of Charles and Mary, drilled to 360 feet. Any trenching or coring on these blocks is planned around live and abandoned service lines.
Well 295 at 8415 Yamamoto Way, drilled in 1989, carried the system's treatment and its only standby power in 2010. The nitrate removal plant serving the whole Grayson system was announced for replacement in 2024, with no completion recorded in any source read.
The half-acre Leroy F. Fitzsimmons Memorial Park with its basketball court, picnic shelter and playground sits on this edge, and the district boundary runs along Stakes and Charles with the San Joaquin River just beyond.
A two-lane road the General Plan classes as a four-lane expressway, linking the community to Highway 33 and Westley, with 3,100 to 3,800 vehicles a day at that junction. Deliveries and plant for any job here arrive along it.
The northern and western edges. The old Planned Development zoning north of the community has expired and use there is limited to agriculture; in 2010 the water system was about 75 percent built out, with the remaining ground mainly north and south.
Lagoons and leach fields bounded by farmland and the river, designed for 100,000 gallons a day and at capacity, listed by the County as at risk during high water. It is the proposed site of a plant that would take Westley's flow as well.
The road crosses the river and the slough here and became impassable in 2011 and 2017. Laird Regional Park, 97 acres at 8250 West Grayson Road, has ball fields, picnic shelters and unpaved parking.
Stanislaus County's Department of Planning and Community Development, through the Building Permits Division at 1010 10th Street, Suite 3400 in Modesto. LAFCO records that the community services district has no land use authority and that responsibility for land use decisions inside its boundaries is retained by the County. The licensed contractor the request is handed to pulls the permit, because the contract, the scheduling and the permit sit with that contractor.
A second County review. In a Special Flood Hazard Area a permit is required before any construction, flood development permits are usually obtained with the building permit, and the flood zone determination is typically made when the building permit application is received. Repairs to an existing structure are reviewed as a possible substantial improvement, which is triggered once their cost exceeds 50 percent of the value of the original structure.
The load is checked first. The community services district runs a plant designed for 100,000 gallons a day that it describes as at capacity, serving 240 residential customers and one commercial customer, and the County proposed no rezoning in Grayson because of the age and limited capacity of that sewer system. A new fixture schedule is set against those figures with the district before the drawings are finished.
It is worth designing around. The City of Modesto's 2021 report for the Grayson system gives hardness at 782 parts per million, sampled in 2020, and total dissolved solids at 1,250 against a 1,000 secondary standard. Water heaters, dishwashers, ice machines and boiler feeds specified for a new kitchen or break room are chosen with that in mind, and the fixture schedule is written accordingly.
Not the whole building, but not just the room either. Single-element alterations that together amount to the alteration of a room or space make that entire room or space accessible, and an accessible path of travel to the altered area comes with the work. Normal maintenance, reroofing, painting and changes to mechanical and electrical systems are not alterations unless they affect the usability of the building. Structural or seismic strengthening the building needs is a separate scope again, priced as structural and safety work.
It is diverted and documented. CALGreen asks that at least 65 percent of the non-hazardous construction and demolition debris from the project is recycled or salvaged, and the load tickets record it. Universal waste, which covers batteries, electronic waste, lamps, cathode ray tubes and aerosol cans, is verified as properly disposed of, and a list of prohibited universal waste materials goes into the construction documents where that applies.
